2020-05-01T00:56:57 < fenugrec> karlp, heh thanks
2020-05-01T00:58:12 < fenugrec> I thought I'd make do with a fixed-zoom , but I just know I would regret that
2020-05-01T01:08:10 < kakimir> any new scopes out there?
2020-05-01T01:08:21 < kakimir> that give a run for the money
2020-05-01T01:10:15 < englishman> fenugrec: I don't think I'm going to be using mine anytime soon .

2020-05-01T01:13:35 < englishman> no. qfn. there are microscopes at work tho. and even there I don't touch assembly that often
2020-05-01T01:27:23 < qyx> meh, figthing with freecad, qcad and kicad
2020-05-01T01:27:32 < qyx> it is like having only one arm and leg
2020-05-01T01:28:05 < qyx> doing an enclosure panel cutouts

2020-05-01T01:34:38 < englishman> ordered some crap from a scientific dropship company in usa. free ship!
2020-05-01T01:34:43 < englishman> they contact me, oh shipping is $100 usd.
2020-05-01T01:34:46 < englishman> no we cant refund.
2020-05-01T01:34:50 < englishman> um, sure
2020-05-01T01:34:54 < englishman> visa disagrees
2020-05-01T01:34:59 < englishman> but go ahead and say that anyway.

2020-05-01T06:29:13 < brdb> is there a way to get NSS on the STM32 to be hardware driven in master mode (single master, not fakakta multi master!)
2020-05-01T06:29:43 < brdb> it doesn't seem to drive the NSS pin (PA4 in my case) high or low. it just sits there, staying low, menacingly!
2020-05-01T06:30:12 < brdb> i've gotten success using GPIO as an slave select, but am not sure how to verify that the SPI message finished sending (there a flag?)
2020-05-01T06:38:23 < Cracki> SPI is multi-slave. the master wouldn't know which nss to drive
2020-05-01T06:38:39 < Cracki> the slave select is per-slave
2020-05-01T06:40:09 < Cracki> NSS does work as a hardware input, but that only makes sense when it's a slave
2020-05-01T06:41:05 < Cracki> (or in multimaster, which doesn't apply to you)
2020-05-01T06:41:29 < Cracki> the message is sent when you get an interrupt, if you enable the interrupt
2020-05-01T06:41:45 < Cracki> *message is sent, then interrupt happens
2020-05-01T06:42:29 < Cracki> brdb, what stm32 do you have
2020-05-01T06:43:27 < Cracki> my f3 says under NSS pin management that it _can_ use NSS as an output automatically

2020-05-01T06:56:42 < brdb> reference manual says the same on mine
2020-05-01T06:57:37 < brdb> Cracki: so when using GPIO as slave select, how do you determine when the send is done to pull the enable high (or low, whichever is active)
2020-05-01T06:57:48 < brdb> with stm32 as SPI master ^
2020-05-01T06:57:57 < brdb> interrupt flag?
2020-05-01T06:58:05 < Cracki> interrupts ye
2020-05-01T06:58:32 < Cracki> usual slave selects idle high, active low
2020-05-01T06:58:43 < Cracki> open drain semantics are popular
2020-05-01T06:59:27 < brdb> oh wait a minute, do i have to set the output to push-pull on the NSS for it to be hardware driven?
2020-05-01T07:00:22 < Cracki> I'd set it to pushpull but don't base that assertion on anything
2020-05-01T07:01:16 < Cracki> whatever choices cubemx gives and decisions it takes from you :>
2020-05-01T07:01:39 < brdb> now where's that pesky interrupt flag for spi
2020-05-01T07:01:47 < brdb> im just using the stm32f0 disco board with libopencm3
2020-05-01T07:02:07 < Cracki> my RM has a whole subsection called "spi interrupts" under spi
2020-05-01T07:10:42 < brdb> just the BSY flag in the status register for SPI
2020-05-01T07:12:26 < brdb> works great Cracki, thanks!
2020-05-01T07:12:55 < brdb> maybe i just need to use GPIOs to run CS/SS for SPI slave devices instead of trying to use NSS for that since i just can't get that to work

2020-05-01T07:15:18 < Cracki> looks like slave select works? or did you have to set it manually

2020-05-01T07:16:55 < brdb> interrupt, that is

2020-05-01T10:47:44 < boddax> yes
2020-05-01T10:48:07 < PaulFertser> boddax: in this case, add a pull-up (stronger than 2k) to any of the data pins and see what it gives.
2020-05-01T10:48:31 < PaulFertser> If pullup is added to D+, you'll see "new full speed device". If to D-, you'll see "new low speed device".

2020-05-01T18:07:34 < Mangy_Dog> quick question, when running serial between a stm32 and a atmega... should i put a little resistor on the atmegs TX line to the stm32? i mean i know stm32 is 5v compatable on most gpio but... jsut wanted to be sure
2020-05-01T18:08:20 < PaulFertser> 5V tolerant pins are all but those that can be muxed to ADC inputs IIRC.
2020-05-01T18:08:32 < PaulFertser> atmega can run on 3.3V too.
2020-05-01T18:08:56 < Mangy_Dog> at a reduced clock
2020-05-01T18:09:16 < PaulFertser> Yep
2020-05-01T18:09:27 < Mangy_Dog> and im having to pass 5v to that board anyway
2020-05-01T18:09:34 < mawk> a resistor for what
2020-05-01T18:09:38 < Mangy_Dog> id rather not have to put in another vreg
2020-05-01T18:09:58 < Mangy_Dog> to bring that 5v tx line down to 3
2020-05-01T18:11:09 < PaulFertser> You shouldn't need it just for that.
2020-05-01T18:11:15 < Mangy_Dog> fair enough
2020-05-01T18:11:22 < mawk> wouldn't you use a level shifter instead of a vreg ?
2020-05-01T18:11:38 < Mangy_Dog> sure
2020-05-01T18:11:54 < Mangy_Dog> but just adds parts to a already populated design
2020-05-01T18:12:01 < Mangy_Dog> trying to simplfy some things

2020-05-01T18:13:30 < mawk> can't you put the arduino serial in open collector mode Mangy_Dog ?
2020-05-01T18:13:33 < mawk> or bitbang it
2020-05-01T18:13:51 < mawk> well you don't need it anyway
2020-05-01T18:14:41 < PaulFertser> Why bother mawk, STM32 has FT pins exactly for this usecase.
2020-05-01T18:15:01 < mawk> yeah

2020-05-01T18:55:14 < Thorn> so I'd like to make Vcc = 1.8V for this system but what about the sd card. 2.7V min
2020-05-01T18:56:05 < Thorn> (because the ldo in the nrf will drop the voltage down to 1.2V anyway)
2020-05-01T19:02:45 < boddax> get 5v from usb
2020-05-01T19:03:21 < Thorn> it' powered from 3 aa batteries
2020-05-01T19:04:23 < Thorn> and if the nrf is powered from 1.8V I'd need a level shifter for the sd card in addition to a dedicated ldo or dc/dc, that's pretty disgusting
2020-05-01T19:04:28 < jpa-> so have LDO for 3.3V to SD card and buck for 1.8V
2020-05-01T19:05:26 < boddax> maybe i m wrong or mistake seen while ago logic circuit using 3 inverters in series to up the V level
2020-05-01T19:05:30 < jpa-> if the NRF io pins can tolerate higher voltages, you could operate with pull-ups to start with and then switch to low voltage mode (if using SDIO)
2020-05-01T19:05:49 < Thorn> it doesn't have sdio
2020-05-01T19:06:15 < jpa-> or if you only need SD card occassionally, switch the whole system Vdd to 3.3V when you need it
2020-05-01T19:07:48 < Thorn> what is the lowest usable voltage of an AA alkaline battery?
2020-05-01T19:08:02 < jpa-> 0.8V is pretty empty
2020-05-01T19:08:38 < Thorn> what about NiMH rechargeable AA
2020-05-01T19:08:58 < Thorn> (because my Magic Mouse can barely work with them, it thinks they're discharged)
2020-05-01T19:09:02 < Thorn> >Apple engineering
2020-05-01T19:09:41 < jpa-> one option would be to just put the three AA in parallel and then boost it up to either 1.8V or 3.3V depending on mode
2020-05-01T19:19:38 < Thorn> it needs the card basically all the time when it isn't sleeping
2020-05-01T19:27:20 < jpa-> can the NRF take 1.2V supply separately, so you could have io voltage at 3.3V while generating 1.2V more efficiently?
2020-05-01T19:28:01 < Thorn> I'll need to re-read the pdf version of the manual but it doesn't appear to be capable of that for whatever reason
2020-05-01T19:28:07 < Thorn> it does have a builtin dc/dc
2020-05-01T19:28:43 < Thorn> I would guess I'll put a buck-boost to 3V and enough passives to run the internal dc/dc, and then try it with & without it on the prototype
2020-05-01T19:29:45 < Thorn> nrf51 had an errata item where the dc/dc negatively affected its radio performance
2020-05-01T19:29:58 < Thorn> the builtin dc/dc
2020-05-01T19:32:29 < Thorn> if it had separate Vdd_core and Vdd_io like fpgas and socs do it would be easier to make the system more efficient
2020-05-01T19:33:10 < Thorn> (btw even the i2s amp has that, plus Vdd_amp)
2020-05-01T19:37:21 < jpa-> if it has external inductors for the buck, it seems like it would likely have a way to feed the 1.2V externally
2020-05-01T19:37:27 < jpa-> as it has the pin anyway

2020-05-01T21:50:55 < qyx> Thorn: I tried to solve the same issue, 1V8 stm32 + SD card
2020-05-01T21:51:10 < qyx> I was lazy to do any sort of level translation
2020-05-01T21:52:23 < qyx> also I think stepping-up from ~1V0 to 1V8 and 3V3 is less efficient than stepping-down from ~4V0 to 3V3 and then 1V8

2020-05-01T22:29:10 < zyp> I think it can, IIRC one of the points is to be able to do 3.3V USB when the rest of the chip is running at a lower voltage
2020-05-01T22:32:13 < Thorn> IIRC that's a separate thing called Vusb
2020-05-01T22:32:18 < Thorn> not Vddio
2020-05-01T22:32:56 < Thorn> or something to that effect
2020-05-01T22:33:32 < Thorn> yes, iirc Vusb is designed to feeds the USB core from Vbus

2020-05-01T22:50:53 < zyp> probably not
2020-05-01T22:51:27 < zyp> also, have you tried just running the sdcard at 1.8V?
2020-05-01T22:51:59 < zyp> IIRC the spec has them starting up at 3.3V and optionally changing to 1.8V, but I assume if they are capable of the latter they might support starting at 1.8V too

2020-05-02T00:23:58 < Cracki> what do you think this is
2020-05-02T00:24:14 < Cracki> he's a cat toying with a mouse
2020-05-02T00:24:18 < Laurenceb> almost like he is an attention seeker
2020-05-02T00:24:30 < Cracki> nah, just autistic as fuck
2020-05-02T00:24:48 < Cracki> he calls it as he sees it, and he called the stock price too high, without saying why he thinks that
2020-05-02T00:25:20 < Cracki> he's having a laugh at irrational meatbags.
2020-05-02T00:27:03 < Cracki> lol his profile picture he's embracing Clown Wworld
2020-05-02T00:27:53 < Cracki> he's a puppet master like trump. farts around and everyone loses their fucking heads
2020-05-02T00:28:23 < BrainDamage> you don't need to be a puppet master to do that
2020-05-02T00:28:42 < BrainDamage> once you're famous, whatever you say, careful or not has potential to make a shitstorm
2020-05-02T00:28:51 < Laurenceb> Donald "drink bleach" Trump
2020-05-02T00:29:06 < Cracki> eh, that's not even a shitstorm, that's just journos reporting the weather. they have nothing else to do
2020-05-02T00:29:22 < Cracki> what dumbass understood him as saying "drink bleach" anyway
2020-05-02T00:29:25 < Mangy_Dog> i genuingly dont know how i feel about him... is he just a lucky rich kid who has to much money and little sense? (remember he didnt make his wealth he was born with a fair bit to begin with) and sometimes hes smart makes some really good pushes in the right direction... spacex tesla..... And hes got a horrid ego one he hates to have tarnished, the whole situation with the cave divers... And 
2020-05-02T00:29:25 < Mangy_Dog> how the hell elon won that court case for defamation
2020-05-02T00:30:18 < Cracki> how much was he given and how much does he have
2020-05-02T00:30:31 < Cracki> orders of magnitude are enough. pls present numbers
2020-05-02T00:30:47 < BrainDamage> eh, about fame, people have as much power as you're willing to pay attention to them
2020-05-02T00:30:48 < Mangy_Dog> i have no idea dont get me wrong im sure he dontaes tons
2020-05-02T00:30:55 < Mangy_Dog> and yes hes now super mega rich
2020-05-02T00:31:01 < Mangy_Dog> but the thing about money is
2020-05-02T00:31:03 < Mangy_Dog> money makes money
2020-05-02T00:31:07 < Mangy_Dog> look at trump
2020-05-02T00:31:08 < Cracki> wait elon musk and ego? "rich kid"? you are missing his intelligence and education, his work...
2020-05-02T00:31:26 < BrainDamage> you'd need to compare growth to people that started with similar wealth in similar time bracket
2020-05-02T00:31:32 < BrainDamage> then you can have a fair comparison
2020-05-02T00:31:35 < Cracki> ye
2020-05-02T00:31:57 < Cracki> I disagree with "he didnt make his wealth"
2020-05-02T00:32:32 < Cracki> that's magical thinking and a license to blame others for one's own bad fortune
2020-05-02T00:33:26 < Mangy_Dog> nonono
2020-05-02T00:33:28 < strata> just keep worshipping elon
2020-05-02T00:33:32 < Mangy_Dog> hes MAde his big wealth sure
2020-05-02T00:33:47 < Mangy_Dog> but he started out with 10s of millions in his pocket
2020-05-02T00:33:51 < strata> what's real wealth?
2020-05-02T00:34:06 < Mangy_Dog> Anyway and dont get me wrong hes an intelligent person
2020-05-02T00:34:14 < Mangy_Dog> i have no idea what his education is though
2020-05-02T00:34:29 < Mangy_Dog> but as a person i still dont know how i feel about it
2020-05-02T00:34:30 < Mangy_Dog> him
2020-05-02T00:34:40 < Cracki> watch any of his appearances on some stage. he's babbling around, his head isn't in the present
2020-05-02T00:34:54 < Mangy_Dog> sorry i didnt mean to compare him to trump in personality or intelligence
2020-05-02T00:34:55 < strata> is it relative? if i have some skills to produce my own food and make shelter for myself and others, and can learn from others and teach what i know... is that more valuable than money?
2020-05-02T00:34:57 < Cracki> he can tell you all about the tech, he loves tech
2020-05-02T00:34:57 < Mangy_Dog> just money makes money
2020-05-02T00:34:57 < BrainDamage> you can separate the personal life with the skills and accomplishments
2020-05-02T00:35:25 < Mangy_Dog> in any case what was his education?
2020-05-02T00:35:29 < Mangy_Dog> is he a developer?
2020-05-02T00:35:35 < BrainDamage> eg a lot of people that contributed to keystone scientific works had truly awful personalities
2020-05-02T00:35:36 < Mangy_Dog> an engineer?
2020-05-02T00:35:39 < Mangy_Dog> programmer?
2020-05-02T00:35:48 < Mangy_Dog> or has he just hired people who are?
2020-05-02T00:36:19 < Mangy_Dog> i dont think hes dumb or anything
2020-05-02T00:36:34 < Mangy_Dog> but billions of people around around could have done what hes done if they started off rich
2020-05-02T00:37:06 < Mangy_Dog> ok maybe not billions
2020-05-02T00:37:10 < Mangy_Dog> but at least millions
2020-05-02T00:37:10 < Cracki> maybe thousands
2020-05-02T00:37:16 < Cracki> you need the mind for it
2020-05-02T00:37:24 < Cracki> just a mind isn't enough, sure
2020-05-02T00:37:28 < Cracki> but just money isn't enough either
2020-05-02T00:37:35 < strata> no
2020-05-02T00:37:44 < strata> you just need money and other people to tell you what to do with it.
2020-05-02T00:37:50 < strata> and get drunk on your own koolaid along the way
2020-05-02T00:38:18 < strata> don't let the baby face techboy charm fool you. elon is of the paypal mafia
2020-05-02T00:38:22 < Cracki> that's a recipe for losing all your money
2020-05-02T00:39:59 < strata> people latched to watching spacex launch starlink sats like it's a great leap for humanity
2020-05-02T00:40:23 < Cracki> I just looked up what trump actually said (video). at most you can blame him for talking nonsense on camera. you can't blame him for dumb people doing retarded things.
2020-05-02T00:40:55 < Cracki> yeah yeah they did it in 1969 already no big deal... except nobody did it again until now
2020-05-02T00:41:07 < strata> you don't give 3rd world shitholes free internet because you're a good hearted person. you do it because it's gonna make paypal more profit when you shackle those nations with cashless digital payment systems.
2020-05-02T00:41:21 < Cracki> starlink isn't about free internet to third worlders
2020-05-02T00:41:29 < Cracki> use your imagination
2020-05-02T00:41:41 < Cracki> it's a global backbone for neuralink
2020-05-02T00:42:07 < strata> whoa, Cracki. let's not get TOO crazy in here. i was already likely about to get told to fuck off for saying what i said.
2020-05-02T00:42:17 < strata> now you wanna increase the tinfoil level to 12,000
2020-05-02T00:42:33 < Cracki> as much tinfoil as his cybercar's body
2020-05-02T00:42:50 < strata> tinfoil doesn't melt covid-19? :)
2020-05-02T00:43:14 < strata> i guess not when oil is -$37 !
2020-05-02T00:43:32 < BrainDamage> his network isn't even covering third world nations - yet
2020-05-02T00:43:56 < BrainDamage> also, it's almost sure that he has commercial interests, why wouldn't you? it's how you make projects work
2020-05-02T00:44:17 < BrainDamage> as in, it's a good known recipe to have a project to succeed
2020-05-02T00:44:21 < Cracki> obviously commercial interests, I don't see anyone denying that
2020-05-02T00:44:38 < BrainDamage> the trick is chosing one that doesn't outright does more harm than good
2020-05-02T00:45:06 < Cracki> evil is very successful. ask google, microsoft, ORACLE, ...
2020-05-02T00:45:44 < Thorn> where do I pullups/pulldowns on sd card signals in spi mode? the internet is all over the place
2020-05-02T00:46:15 < Thorn> every possible combination can be found (and most circuits look like eagle)
2020-05-02T00:46:41 < Cracki> does the SD spec say?
2020-05-02T00:48:38 < zyp> qyx, I was wondering, is it feasible to have multiple depths of backplanes in the same chassis?
2020-05-02T00:49:59 < zyp> I assume if you mount two sets of rails for mounting backplanes, the longer cards will happily fit in between the first set of rails, but I guess the longer card holders would conflict
2020-05-02T00:50:57 < zyp> which means it'd probably work using shorter card holders for all cards and let them hang free between the two levels
2020-05-02T00:58:38 < zyp> by card holders I mean guide rails
2020-05-02T01:03:28 < Thorn> ok looks like pulldowns (+ series resistors) are for 5V MCUs
2020-05-02T01:03:39 < Thorn> and the spec seems to say pull up everything

2020-05-02T08:10:11 < Cracki> ColdKeyboard, what's the plan? STM32 with DAC, read a wav from sd card (I see a bunch of examples for card access)? or pick a fat stm32 and store shit in flash
2020-05-02T08:10:44 < Cracki> boddax, isn't it always JST?
2020-05-02T08:13:21 < Cracki> browse those (jst/moles/... tabs on the top), google showed me something that looks very much like yours https://www.sconect.com/wire-to-board-connector/

2020-05-02T08:50:52 < dongs> if its 1mm its SH if its 1.25 its picoblade
2020-05-02T08:52:07 < boddax> Cracki found , its 1.25 jst type also found local reseller has them and ordered thanks
2020-05-02T08:52:42 < Cracki> you wanna check the pitch maybe
2020-05-02T08:53:03 < Cracki> the general shape needn't imply pitch, unless molex make them in just the one
2020-05-02T08:53:36 < boddax> have try with 2.54 header 1 and 3 fits perfect mean exactly half 1.25
2020-05-02T08:55:11 < boddax> playng with this ip camera arm926 + linux make me crazy ..has usb unused lacking connector
2020-05-02T08:56:49 < Cracki> it could be 1.27 too :>
2020-05-02T08:57:47 < boddax> lol you right ..very inexpensive better i order all 3 pitch ..its just 3 oe 4 euro things

2020-05-02T11:19:45 < qyx> for DAQ I identified the main issue is not the circuit complexity itself but rather the lack of enough space for conenctors on the front panel
2020-05-02T11:20:38 < qyx> so my reasoning is it may be better to provide wider boards than deeper ones
2020-05-02T11:20:59 < qyx> the only downside is there are no suitable guide rails
2020-05-02T11:22:13 < qyx> for wider boards - I am considering (in a horizontal subrack) placing two vertical rails prividing a smaller vertical sub-sub-rack
2020-05-02T11:32:10 < zyp> that sounds like a consequence of going with 2U
2020-05-02T11:33:13 < zyp> because of mounting rails and stuff, 2U boards are just above half as high as 3U boards, and then you have mounting holes taking some of the front edge area as well
2020-05-02T11:33:22 < zyp> so a 3U board would have over twice as much room for connectors

2020-05-02T12:37:36 < Thorn> do I need a mosfet to switch microSD power on/off?
2020-05-02T12:37:46 < Thorn> even the standard seems to recommend it
2020-05-02T12:38:19 < qyx> depending on the manufacturer, uSD in idle state draws about 250uA-1mA
2020-05-02T12:38:36 < Thorn> oops that is a lot of µA
2020-05-02T12:38:54 < qyx> if you are using SPI, apparently there is no possiblity to check when you may power off the card
2020-05-02T12:39:09 < qyx> as it is doing operations on the background even when the write is confirmed
2020-05-02T12:39:22 < qyx> but citation needed, I read it on some forum
2020-05-02T12:40:04 < qyx> there was a general consensus you have to wait up to 1s before powering off the card

2020-05-02T13:44:57 < onio> Hi all, just thinking out aloud here. I recently have been doing STM32 development. I understand that ARM have "Cortex Microcontroller Software Interface Standard" (CMSIS)
2020-05-02T13:45:34 < onio> my question is this now owned by Keil, I can't seem to find much information without references to Keil. 
2020-05-02T13:46:28 < PaulFertser> onio: and what the question is?
2020-05-02T13:46:41 < onio> My preferred development OS is Ubuntu and don't want to use Keil, does this mean I can't use feature such as event recording?
2020-05-02T13:46:57 < onio> with STM32CubeIDE
2020-05-02T13:47:23 < PaulFertser> onio: what exactly is event recording? What is an event, how is it generated and what records it?
2020-05-02T13:48:15 < onio> This is an feature that some ARM processor have that allow them to allocate part of their memory for debugging purposes
2020-05-02T13:48:45 < PaulFertser> That's too vague of a description.
2020-05-02T13:49:48 < onio> PaulFertser, I am talking about this https://www.keil.com/pack/doc/compiler/EventRecorder/html/index.html
2020-05-02T13:50:42 < onio> or more precisely this https://www.keil.com/pack/doc/compiler/EventRecorder/html/er_use.html#printf_redirect
2020-05-02T13:53:37 < PaulFertser> onio: do you not have ITM available?
2020-05-02T13:54:45 < onio> I have to check I am using the STM32L073 
2020-05-02T13:56:21 < Steffanx> This sounds like its similar to RTT of segger and what they build on top of that
2020-05-02T13:57:03 < onio> No I don't think my microcontroller has it, just done a search in the datasheet
2020-05-02T13:57:47 < Steffanx> If you have an SWO pin you probably do have it.
2020-05-02T13:58:02 < onio> Steffanx, yes segger does have support for it via their J-Link debugger
2020-05-02T13:58:06 < Steffanx> Its a cortex-whatever thing, and those are usually not mentioned in a datasheet
2020-05-02T13:59:00 < Steffanx> If you really want such feature you can always reflash your stlink with jlink fw
2020-05-02T13:59:13 < Steffanx> (If you have an stlink ofcourse ;) )
2020-05-02T14:00:24 < PaulFertser> onio: OpenOCD supports Segger RTT with any adapter
2020-05-02T14:00:31 < PaulFertser> (with an out-of-tree patch)
2020-05-02T14:00:47 < PaulFertser> onio: you can also use arm semihosting if you really need to
2020-05-02T14:01:03 < Steffanx> Oh L0 is an M0(+) ofcourse, not sure if that one does ITM
2020-05-02T14:03:33 < onio> PaulFertser, Steffanx cool thanks
2020-05-02T14:04:19 < Steffanx> System View is a pretty nice tool imho. To visualize an RTOS running its tasks, but damn its buggy
2020-05-02T14:04:32 < Steffanx> Especially the newer versions.
2020-05-02T14:06:41 < onio> Steffanx, when you mean stlink are you referring to the actual debugger or it can be the ones they put at the end of the nucleo boards?
2020-05-02T14:08:09 < onio> Steffanx, is System View another IDE?
2020-05-02T14:10:48 < Steffanx> No, system view is a separate tool by SEGGER. Its mainly a visualisation tool for stuff they build on top of RTT
2020-05-02T14:11:12 < Steffanx> It works on the nucleo's stlink as well. 
2020-05-02T14:11:19 < onio> Steffanx, ah thanks
2020-05-02T14:11:29 < Steffanx> As long as its not the new stlink v3
2020-05-02T14:11:42 < PaulFertser> Steffanx: does it work on non-nucleo stlinks? I think it was meant only for OBD versions.
2020-05-02T14:11:45 < Steffanx> (Some huge stm32f7)
2020-05-02T14:11:58 < Steffanx> I'm not sure PaulFertser 
2020-05-02T14:12:03 < Steffanx> Never tried it
2020-05-02T14:14:55 < Steffanx> I guess its on-board only. Thats what segger says.

2020-05-02T18:04:51 < onio> PaulFertser, not sure if you are still around based on your recommendation eariler I went to look up semihosting on the STM32 and and found a video which I followed by I am getting errors as shown here
2020-05-02T18:05:01 < onio> https://paste.ubuntu.com/p/Z2nZKt2VwP/
2020-05-02T18:05:50 < onio> I am using the OpenOCD debug option in the STM32CubeIDE
2020-05-02T18:08:46 < PaulFertser> onio: looking
2020-05-02T18:10:39 < PaulFertser> onio: how do you run openocd, what commands does it receive?
2020-05-02T18:11:10 < PaulFertser> What and why is trying to add a breakpoint?
2020-05-02T18:11:46 < onio> I don't know I don't have any breakpoint set.
2020-05-02T18:11:53 < PaulFertser> onio: do you get any errors right after doing "load" in GDB?
2020-05-02T18:12:00 < PaulFertser> onio: what happens if you do "c" after load?
2020-05-02T18:12:22 < onio> I am currently running from the IDE 
2020-05-02T18:12:31 < PaulFertser> Well...
2020-05-02T18:12:38 < zyp> semihosting is using a breakpoint as a semihosting syscall
2020-05-02T18:13:26 < PaulFertser> zyp: but it's not like openocd is supposed to be inserting it :)
2020-05-02T18:14:00 < zyp> true
2020-05-02T18:14:37 < onio> PaulFertser, when you send do "c" after load? how do I do that?
2020-05-02T18:15:15 < PaulFertser> onio: I just run gdb and type commands
2020-05-02T18:15:25 < PaulFertser> gdb, "tar ext :3333", load, c
2020-05-02T18:18:01 < onio> thanks let me try. I assume I would have to use the STM32CubeIDE gdb with the elf file right?
2020-05-02T18:18:26 < PaulFertser> onio: to "load" (which means flashing the target with your code) yes
2020-05-02T18:18:43 < PaulFertser> onio: you can use multiarch gdb too, but probably you'll need to set the architecture manually with that.
2020-05-02T18:18:51 < PaulFertser> set gnutarget ...
2020-05-02T18:19:27 < onio> alright thanks

2020-05-02T20:11:43 < kakimir> I just thought the negative wire is equal to gnd pin
2020-05-02T20:11:45 < kakimir> or something
2020-05-02T20:11:59 < BrainDamage> no, they are read with a differential amplifier

2020-05-02T20:12:53 < kakimir> so I don't need isolation for let say throwing a bunch of thermocouples to engine exhaust manifold?
2020-05-02T20:13:20 < jpa-> at least not from each other, depending on your supply voltage and other connections you may still need isolation as a whole
2020-05-02T20:13:32 < kakimir> actually I need if I connect the ground but not for separate tc ics but for power supply maybe
2020-05-02T20:14:01 < BrainDamage> you might want to tie your circuit ground to the chassis
2020-05-02T20:14:15 < kakimir> that is okay?
2020-05-02T20:14:20 < BrainDamage> because cars can develop significant electrostatic charge
2020-05-02T20:14:46 < BrainDamage> you can tie it with a large resistor
2020-05-02T20:14:49 < BrainDamage> to limit current
2020-05-02T20:15:13 < kakimir> okay how about is there 4channel thermocouple meters ready made I could use?
2020-05-02T20:15:42 < kakimir> I know the answer
2020-05-02T20:16:00 < kakimir> I tried to ask if I should buy one

2020-05-02T20:18:47 < kakimir> that is pretty steep pricetag
2020-05-02T20:19:06 < kakimir> not if you really need it but
2020-05-02T20:20:27 < kakimir> I think I throw some tc ics and arduino in a box and connect the box to computer
2020-05-02T20:20:57 < BrainDamage> careful about the arduino-> pc connection, you'll need isolation there
2020-05-02T20:21:20 < kakimir> maybe
2020-05-02T20:21:26 < BrainDamage> again, several kV of electrostatic charge on the chassis
2020-05-02T20:21:40 < BrainDamage> and a big surface for large capacitance

2020-05-02T23:15:44 < emeb> or do you slave it to SAI2?
2020-05-02T23:17:22 < Steffanx> No, its just "standalone" being a I2S master used to read some stream from a bluetooth device.
2020-05-02T23:17:44 < emeb> ic
2020-05-02T23:18:24 < emeb> the R pkg only brings out the SAI1_A_SD line, so it has to be synced to SAI2 for I2S
2020-05-02T23:19:02 < Steffanx> ah, ok. 
2020-05-02T23:19:37 < Steffanx> i missed that part (i case you mentioned that before)
2020-05-02T23:19:53 < emeb> that was the test I did the other day - to see if that actually worked (it did) even though CubeMX says the only thing you can do with SAI1_A is SPDIF.
2020-05-02T23:20:03 < emeb> tl;dr - CubeMX lies.
2020-05-02T23:21:00 < Steffanx> nah, CubeMX is just to dumb to do that configuration
2020-05-02T23:21:36 < emeb> yep
2020-05-02T23:21:57 < emeb> there are many ways that CubeMX falls short.

2020-05-02T23:24:36 < emeb> but it wouldn't surprise me if everyone else here is too pro to stoop to using such a tool :D
2020-05-02T23:26:11 < Steffanx> Im not pro. So i used it. But i often do verify it using the info in the datasheet

2020-05-02T23:29:19 < zyp> I've tried it, probably saves time for simple projects, but I still prefer doing complex pinouts by hand

2020-05-03T00:39:31 < Cracki> why does it feel spoken to
2020-05-03T00:39:48 < zyp> the pid_* lines are from the PID decoder that drive the receiver state machine, they strobe once they recognize a pid
2020-05-03T00:40:07 < Cracki> so... it felt spoken to?
2020-05-03T00:40:19 < zyp> yes
2020-05-03T00:40:31 < Cracki> the packet before it has... a different or same pid?
2020-05-03T00:40:51 < zyp> same, they are all IN tokens
2020-05-03T00:40:53 < Cracki> eyeballing the signals, they look equal up to the blip
2020-05-03T00:41:08 < Cracki> so... it's treating the same data differently
2020-05-03T00:41:37 < zyp> https://bin.jvnv.net/file/zBIbV.png <- it's coming before the whole PID is received, so I'm guessing the deserializer is off by a bit

2020-05-03T01:27:36 < zyp> hmm
2020-05-03T01:27:43 < Steffanx> Mmh
2020-05-03T01:28:15 < zyp> the valid signal is just a combinatorial check on the two low bits of a counter, checking if they are 2
2020-05-03T01:28:58 < zyp> the counter is only ever incremented or reset, so no logic error should lead to it being valid twice in a row
2020-05-03T01:29:57 < Cracki> what do you do with the result of that combinatorial logic, act on its edges maybe?
2020-05-03T01:30:55 < Cracki> sounds like it's incrementing faster than anticipated

2020-05-03T01:38:50 < Cracki> can you observe that counter increment?
2020-05-03T01:38:58 < zyp> just did that: https://bin.jvnv.net/file/D2z3O.png
2020-05-03T01:39:08 < zyp> it is fucking up
2020-05-03T01:44:44 < zyp> I guess this must be a metastability issue, it's supposed to either increment or reset and it doesn't do either
2020-05-03T01:45:16 < zyp> I'm gonna try some stuff
2020-05-03T01:47:14 < invzim> is the rest clocked into the 48mhz clock?
2020-05-03T01:47:41 < invzim> (is it an async reset)
2020-05-03T01:47:52 < zyp> it's sync
2020-05-03T01:48:19 < zyp> https://paste.jvnv.net/view/ZE8HB
2020-05-03T01:48:28 < catphish> does anyone know the name of the C definition for the STM32 unique device ID?
2020-05-03T01:48:39 < invzim> hey, that's not vhdl - how dare you! :)
2020-05-03T01:49:07 < invzim> I don't speak much fpga, and then only vhdl
2020-05-03T01:49:11 < zyp> catphish, https://cgit.jvnv.net/arcin/tree/main.cpp#n227
2020-05-03T01:50:03 < catphish> i found UID_BASE that points to 0x1FFF7A10
2020-05-03T01:50:38 < zyp> yeah, varies from family to family
2020-05-03T01:50:38 < zyp> https://cgit.jvnv.net/cardio/tree/bootloader.cpp#n177
2020-05-03T01:51:01 < catphish> that's probably it then, thanks!
2020-05-03T01:51:07 < catphish> address look close
2020-05-03T01:51:44 < catphish> yep, from the RM, Base address: 0x1FFF 7A10
2020-05-03T01:51:48 < catphish> thanks!
2020-05-03T01:52:17 < catphish> i like to use the STM provided constants where i can :)
2020-05-03T01:53:28 < catphish> also, i just discovered that my build environment has a stdlib! life is so much more tolerable
2020-05-03T01:53:58 < invzim> catphish: UID_BASE
2020-05-03T01:54:54 < catphish> invzim: thanks, i just found that too :) looks like the address is all i need
2020-05-03T01:54:57 < zyp> okay, wtf, I added a pid error detection, now I'm finding other ways the clock recovery can fuck up too
2020-05-03T01:55:07 < catphish> i'll just be passing it to memcpy to do the necessary :)
2020-05-03T01:55:33 < invzim> catphish: be aware, the uid's are far from random
2020-05-03T01:55:48 < catphish> my understanding is that they're quite predictabl
2020-05-03T01:56:01 < catphish> ie they contain batch numbers and die coordinates
2020-05-03T01:56:27 < catphish> but that's fine, i just need it to be unique
2020-05-03T01:57:14 < catphish> i also need to use it to generate a MAC address
2020-05-03T01:57:17 < invzim> crypto/protection stuff?
2020-05-03T01:57:39 < Steffanx> Generate a mac address. Damn it catphish
2020-05-03T01:58:02  * invzim alerts the IEEE police
2020-05-03T01:58:33 < catphish> invzim: yes and no, i need an illegally generated MAC address, and a unique identifier so that my server can tell devices apart
2020-05-03T01:58:45 < zyp> https://bin.jvnv.net/file/EjqNp.png <- here the counter/valid signals are looking good, but the stuff that's supposed to sync up the differential edges is completely broken
2020-05-03T01:59:36 < catphish> come to think of it, since each one will need to be burned with a random crypto key too, i suppose i could just generate my own UID at the same time
2020-05-03T01:59:38 < zyp> catphish, bit late now, but you should just have slapped one of those mac addr eeproms on it
2020-05-03T01:59:56 < catphish> mac addr eeproms?
2020-05-03T02:00:09 < catphish> that sounds like a nonsense product
2020-05-03T02:00:23 < zyp> 2AA02E48 or similar
2020-05-03T02:00:30 < Steffanx> Why nonsense?
2020-05-03T02:00:37 < Steffanx> Gonna buy a block yourself?
2020-05-03T02:01:03 < zyp> 25AA02E48*
2020-05-03T02:01:16 < catphish> well, if you're going to sell MAC addresses, why not just email them?
2020-05-03T02:01:40 < Steffanx> Because now you just put the ic on your pcb
2020-05-03T02:01:47 < catphish> why bother to manufacture, distribute and solder a whole IC
2020-05-03T02:01:52 < Steffanx> And need no administration what so ever
2020-05-03T02:02:02 < zyp> that.
2020-05-03T02:02:10 < zyp> no need to provision a valid mac addr later
2020-05-03T02:02:13 < catphish> i guess i can see the benefit, but still seems like a waste
2020-05-03T02:02:27 < zyp> and you can use the eeprom for other stuff too
2020-05-03T02:02:38 < Thorn> 128 whole bytes of storage!
2020-05-03T02:02:43 < Steffanx> Yeah
2020-05-03T02:02:57 < catphish> anyway, honestly, i have little need for a globally unique MAC, i'll just have it generate a local one at first boot
2020-05-03T02:03:10 < zyp> i2c eeproms are dirt cheap, commonly used to store ID information
2020-05-03T02:03:15 < Steffanx> Managing all that info during production is just a PITA.
2020-05-03T02:03:15 < catphish> conflicts seem pretty implausible :)
2020-05-03T02:03:35 < zyp> but yeah
2020-05-03T02:03:57 < Steffanx> I'm gonna laugh when  it does break something :P
2020-05-03T02:04:00 < zyp> my workstuff is deriving local MACs from type/serial stored in OTP
2020-05-03T02:04:03 < catphish> lol
2020-05-03T02:04:36 < catphish> i still have to somehow get a known but random crypto key into each device
2020-05-03T02:04:46 < catphish> so they'll be uniquely programmed anyway
2020-05-03T02:05:13 < zyp> my workstuff is gonna run on a dedicated network with limited connection to other stuff, and the type/serial data is uniquely provisioned
2020-05-03T02:05:50 < catphish> it's annoying, because the hardware RNG could automatically provision everything, but it needs to be known
2020-05-03T02:05:56 < zyp> why known but random?
2020-05-03T02:06:14 < karlp> 24aa00 ftw if you need macs, just do it.
2020-05-03T02:06:28 < zyp> catphish, no PKI?
2020-05-03T02:06:33 < catphish> known because i'm doing symmetric crypto
2020-05-03T02:06:39 < zyp> why?
2020-05-03T02:06:41 < catphish> zyp: nein
2020-05-03T02:06:47 < catphish> because i have no idea how
2020-05-03T02:07:01 < zyp> use a lib? :p
2020-05-03T02:07:32 < catphish> never
2020-05-03T02:08:12 < Steffanx> What did you implement yourself?
2020-05-03T02:08:23 < catphish> but actually, if i can send the key to the server by public key encryption, that would be a cool bonus
2020-05-03T02:08:36 < catphish> Steffanx: everything :)
2020-05-03T02:08:50 < invzim> what could possibly go wrong :)
2020-05-03T02:08:54 < Steffanx> I mean what symmetric crypti
2020-05-03T02:08:57 < catphish> actually, no, i did just pull in libraries for SHA256 and AES
2020-05-03T02:09:12 < Steffanx> Or did you invent catcryption?
2020-05-03T02:09:34 < catphish> Steffanx: just AES256-CBC for encryption and SHA256-HMAC for signing
2020-05-03T02:09:58 < catphish> those i am using simple libraries for
2020-05-03T02:10:14 < Steffanx> Ooooh :p
2020-05-03T02:10:33 < catphish> but those both require a preshared key
2020-05-03T02:11:22 < invzim> https://github.com/kmackay/micro-ecc
2020-05-03T02:11:30 < invzim> ECDSA for signing
2020-05-03T02:11:40 < invzim> private key is yours
2020-05-03T02:12:06 < invzim> I use it to verify integrity of bootloader
2020-05-03T02:12:17 < catphish> cool
2020-05-03T02:12:18 < invzim> public key written to OTP
2020-05-03T02:12:53 < invzim> also include UID in the hash
2020-05-03T02:13:02 < zyp> integrity? sounds more like DRM
2020-05-03T02:13:12 < invzim> and enable ROP-level 2 :)
2020-05-03T02:15:32 < Mangy_Dog> on stmf103 does PC 13 14 and 15 have internal pulldowns?
2020-05-03T02:17:07 < catphish> i'm not totally sure how to use public key encrption here
2020-05-03T02:18:03 < catphish> there's no way for the board to prove its identity without presharing something
2020-05-03T02:18:07 < zyp> catphish, generate a keypair on the mcu, send public key to server, server encrypts shared symmetric key and sends it back
2020-05-03T02:19:04 < catphish> i guess you just trust the board the first time it connects
2020-05-03T02:19:17 < catphish> then after that you have established keys
2020-05-03T02:19:29 < zyp> server should have a provisioning mode where you have to accept the fingerprint of new devices
2020-05-03T02:21:27 < zyp> okay, it was 100% a metastability issue
2020-05-03T02:21:38 < zyp> I added flipflops to the input and the problem went away

2020-05-03T02:37:36 < Thorn> I want to do a board with a soc and ddr3 but I don't want to make yet another SBC, especially if it's little more than just a breakout
2020-05-03T02:37:44 < Thorn> one of my ultimate goals is to design an "IoT" gateway (SDR based) but I don't yet have a clear design in mind and am afraid I'm going to spend a lot of time on it and probably make serious mistakes, and respins will cost money
2020-05-03T02:37:47 < Thorn> what do
2020-05-03T02:39:58 < Ultrasauce> prototype on an existing sbc?

2020-05-03T02:42:08 < zyp> yeah, use an existing SBC or module for prototyping
2020-05-03T02:42:10 < Thorn> that won't teach me ddr3 layout or soc implementation lol
2020-05-03T02:42:21 < zyp> once you have it down, roll your own board
2020-05-03T02:42:30 < Thorn> but it will help shape the design
2020-05-03T02:42:51 < zyp> if you want do try parts of it, make them modular
2020-05-03T02:43:02 < zyp> but then you kinda do end up making your own breakout
2020-05-03T02:43:39 < Thorn> and I have a feeling that if i want an SDR I should look at zynq, not mp1 or similar
2020-05-03T02:49:29 < Thorn> and zynq is a whole another level compared to e.g. mp1

2020-05-03T07:01:23 < jadew> actually I fixed it two days ago, yesterday I spent most of the day calibrating it
2020-05-03T07:03:51 < jadew> what strikes me as odd, is that the amplitude is not particularly accurate even after calibration, so I'm not sure if I'm doing something wrong or if there's something wrong with it
2020-05-03T07:05:05 < jadew> up to about 12.5 GHz, it has an accuracy of +- 0.5 dB which is not great
2020-05-03T07:05:23 < jadew> and it gets a bit worse between that and 13.2 GHz
2020-05-03T07:06:18 < jadew> the good part is that it seems to be stable, so I guess I can apply amplitude correction, but I find it strange that after precise calibration, it still displays something wrong
2020-05-03T07:06:48 < jadew> for the most part the error is less than 0.2 dB, but still
2020-05-03T07:07:28 < Cracki> how precise is it supposed to be?
2020-05-03T07:07:37 < jadew> I haven't checked lol
2020-05-03T07:07:54 < jadew> I'm just thinking about what the calibration does really
2020-05-03T07:08:02 < jadew> I think it's not doing straight interpolation
2020-05-03T07:08:33 < jadew> it must do something else, otherwise I can't see why it would display anything other than the exact value, especially at the calibration points
2020-05-03T07:09:14 < Cracki> some summing over some range?
2020-05-03T07:11:17 < jadew> can't find accuracy specs
2020-05-03T07:17:12 < jadew> it's specified as uncertainty for various stuff in the signal path
2020-05-03T07:17:32 < jadew> still doesn't explain what I'm observing
2020-05-03T07:23:02 < Cracki> might this help to "manage your expectations" https://community.keysight.com/community/keysight-blogs/rf-test/blog/2016/10/14/calibration-data-how-to-use-what-you-know

2020-05-03T08:50:20 < Spirit532> I guess I'll try removing it...
2020-05-03T08:51:00 < boddax> check with multim

2020-05-03T09:08:37 < Spirit532> USB is the only peripheral not working
2020-05-03T09:09:08 < boddax> you said generating bad code
2020-05-03T09:09:23 < Spirit532> CubeMX generating bad code
2020-05-03T09:12:00 < Cracki> I can't remember, did you build an example from CubeG4 and run that on your device?
2020-05-03T09:12:35 < Spirit532> not an example, just the default cubemx project
2020-05-03T09:12:49 < Spirit532> clicked usb, clicked cdc middleware, enabled CRS, and let it autogen the clocks
2020-05-03T09:13:02 < Cracki> try an example
2020-05-03T09:13:10 < Spirit532> where are those?

2020-05-03T09:17:23 < Spirit532> let's see if that works
2020-05-03T09:20:14 < Spirit532> yeah the example project is identical
2020-05-03T09:20:26 < Spirit532> except for the larger chip, it's feeding 150Mhz into "To USB" on the clock diagram
2020-05-03T09:20:32 < Spirit532> which screams at me here
2020-05-03T09:20:50 < Cracki> heh
2020-05-03T09:21:07 < Cracki> how much identical is identical
2020-05-03T09:21:20 < Spirit532> no peripherals enabled, the rest is the same
2020-05-03T09:21:24 < Cracki> what does it do when you build and flash it
2020-05-03T09:21:33 < Spirit532> nothing because it's a different chip and different package
2020-05-03T09:21:43 < Cracki> (with clock adjusted as needed of course)
2020-05-03T09:21:51 < Cracki> eh that shouldn't stop it
2020-05-03T09:22:12 < Spirit532> it's cube, of course it stops it
2020-05-03T09:22:20 < Cracki> you have a ... G431CB
2020-05-03T09:22:24 < Cracki> what's the closest match
2020-05-03T09:22:40 < Spirit532> only one example project, for a G474QETX
2020-05-03T09:23:33 < Cracki> you could pick one from the nucleos
2020-05-03T09:23:40 < Spirit532> nope, only one example
2020-05-03T09:24:15 < Cracki> boo those have no usb application example
2020-05-03T09:24:42 < Cracki> oh well, adjust it to your device maybe?
2020-05-03T09:24:51 < Spirit532> don't think I can
2020-05-03T09:29:25 < Spirit532> I can send you this project if you want to look at it

2020-05-03T09:47:27 < Spirit532> having no experience implementing USB really helps here
2020-05-03T09:53:09 < Cracki> do you have a G4 disco/nucleo around to sanity-check?
2020-05-03T09:53:20 < Spirit532> no :(
2020-05-03T09:53:26 < Cracki> maybe it's _something_ with your custom board's design, or the soldering, or something is dead/broken
2020-05-03T09:54:17 < Cracki> I have no experience implementing usb which is why I'm so glad their code "just works"... except their apis for sending and receiving suck. no line buffering or any buffering really.
2020-05-03T09:54:31 < Cracki> you send a char, you waste a whole transfer.

2020-05-03T09:55:24 < Cracki> ok yes, the semantics should be, you send a char or however much at once, that's a transfer right away, but while that's underway, anything else you "send" goes in a buffer... and they don't give you that convenience.
2020-05-03T09:55:27 < Spirit532> and I removed D4 to test, no change

2020-05-03T10:00:41 < Cracki> sad noise, their appnote mentions no g4
2020-05-03T10:02:01 < boddax> To be compliant with the USB 2.0 full-speed electrical specification, the USB_DP (D+) pin must be pulled up to a voltage in the 3.0 to 3.6 V range with a 1.5 kΩ resistor.
2020-05-03T10:02:13 < Cracki> yes, some STM32 have those internally
2020-05-03T10:02:31 < Cracki> and that pullup must only be engaged once vbus is detected
2020-05-03T10:03:16 < boddax> enabled by soft..cubemx settings?
2020-05-03T10:03:19 < Cracki> no
2020-05-03T10:03:28 < Cracki> in bus powered, you can just tie it to your vcc
2020-05-03T10:03:35 < Cracki> in self powered,... you have to sense vbus
2020-05-03T10:03:52 < Spirit532> D+ is pulled up
2020-05-03T10:03:57 < Cracki> and engage it as needed... I think there are STM32 that also do this internally, but at least mine doesn't, it needs me to do this shit
2020-05-03T10:04:12 < Spirit532> I see no *mention* of vbus here
2020-05-03T10:04:21 < Cracki> g431 RM says USB connect / disconnect capability (controllable embedded pull-up resistor on USB_DP line)
2020-05-03T10:04:34 < Spirit532> yes, but controllable WHERE
2020-05-03T10:05:19 < boddax> you can try manually add it 
2020-05-03T10:05:29 < Cracki> don't add it
2020-05-03T10:05:37 < Cracki> their usb peripheral probably handles it already
2020-05-03T10:05:40 < Spirit532> I am NOT sensing vbus here

2020-05-03T10:05:45 < Spirit532> anywhere

2020-05-03T10:05:57 < Cracki> ok well

2020-05-03T10:58:19 < Cracki> you can sacrifice nucleos too
2020-05-03T11:00:26 < zyp> Spirit532, does the g4 have the device only core or the OTG core?

2020-05-03T11:02:12 < zyp> on linux, you'll get a report in dmesg when the D+ pullup is detected, which is the beginning of enumeration
2020-05-03T11:02:46 < Spirit532> I wonder if I can do that through WSL

2020-05-03T11:02:58 < Spirit532> :<
2020-05-03T11:03:31 < zyp> anyway, I think windows gives some error too when a device is detected but doesn't enumerate properly
2020-05-03T11:03:43 < Spirit532> yes, code 43 lol
2020-05-03T11:03:48 < zyp> and you're not even getting that, I assume?
2020-05-03T11:04:00 < Spirit532> it is detected but I'm getting "device descriptor request failed"
2020-05-03T11:04:36 < zyp> ah, then the pullup is okay, something else is the problem
2020-05-03T11:05:02 < Spirit532> so definitely a code fuckup?
2020-05-03T11:05:13 < zyp> not necessarily
2020-05-03T11:05:21 < Spirit532> what else could it be then?

2020-05-03T11:05:35 < zyp> you can have swapped DM/DP so it's trying to enumerate it as a low speed device

2020-05-03T11:06:04 < Spirit532> it looks correct to me

2020-05-03T11:06:45 < Spirit532> see this
2020-05-03T11:06:56 < Spirit532> 34 is DP in the datasheet
2020-05-03T11:08:20 < zyp> uh, wait
2020-05-03T11:08:28 < zyp> is pin 5 on the usb socket just floating?
2020-05-03T11:08:52 < zyp> oh, shelved polygon
2020-05-03T11:09:03 < zyp> I assume it's connected when poured
2020-05-03T11:09:31 < zyp> double check that
2020-05-03T11:31:49 < Spirit532> I fixed it.
2020-05-03T11:32:00 < Spirit532> The fucking connector was defective, and it LOOKED like it soldered on
2020-05-03T11:32:09 < Spirit532> but it only made contact after serious reflow and pressure
2020-05-03T11:32:13 < Spirit532> D- was gone, you were right.

2020-05-03T21:03:03 < Mangy_Dog> the scandinavian countries arent so sucky
2020-05-03T21:03:19 < Thorn> (1) pin-package delays for stm32mp1 aren't available anywhere on st.com, you need to contact them to receive the info
2020-05-03T21:03:20 < Steffanx> i bet it has sucky places as well
2020-05-03T21:03:38 < Thorn> (2) altium pin-package delay support is pretty useless
2020-05-03T21:04:40 < Mangy_Dog> soooo mp1 is more a soc with a mcu built in?
2020-05-03T21:04:53 < mawk> isn't it how it was sold anyway ?
2020-05-03T21:04:55 < Mangy_Dog> ive seen it being mentioned a couple of times recently
2020-05-03T21:04:59 < mawk> cortex a with cortex m in it
2020-05-03T21:05:32 < Mangy_Dog> cortex A is soc?
2020-05-03T21:05:45 < Mangy_Dog> ive not really kept up with the namkign schemes for arm chips properly  :/
2020-05-03T21:05:52 < mawk> well cortex a is the regular stuff
2020-05-03T21:05:55 < mawk> you have in your mobile phone
2020-05-03T21:06:00 < mawk> so you can call it soc sure
2020-05-03T21:06:04 < Mangy_Dog> ok
2020-05-03T21:06:11 < mawk> but I guess "soc" is when you have lot more on it like rf stuff and all
2020-05-03T21:06:17 < mawk> not sure
2020-05-03T21:06:18 < Mangy_Dog> ahh
2020-05-03T21:06:30 < Mangy_Dog> but in this case its more just a "desktop" cpu?
2020-05-03T21:06:36 < Mangy_Dog> ok not desktop
2020-05-03T21:06:37 < mawk> yes cortex A is the desktop cpu
2020-05-03T21:06:41 < mawk> if you want
2020-05-03T21:06:45 < Mangy_Dog> nods
2020-05-03T21:06:57 < mawk> the one on rpi for instance
2020-05-03T21:07:11 < Mangy_Dog> nods
2020-05-03T21:07:59 < Mangy_Dog> skim reading the stm page
2020-05-03T21:08:03 < Mangy_Dog> its interesting
2020-05-03T21:08:27 < Mangy_Dog> im currently picturing full control units with displays for 3d printers and other hardware :p
2020-05-03T21:09:16 < Mangy_Dog> though right nwo i havent got the foggiest how you would write code for it
2020-05-03T21:10:20 < mawk> there's probably a st linux support fo rit
2020-05-03T21:11:54 < Mangy_Dog> even then how do you run code ? how would you differentiate between mpu and cpu?
2020-05-03T21:12:19 < mawk> there's probably some shared memory between the two so the cpu can talk to the mcu
2020-05-03T21:12:23 < mawk> and shared registers
2020-05-03T21:12:34 < mawk> but you know which code runs where since you wrote that code and placed that code yourself
2020-05-03T21:12:37 < Mangy_Dog> or do you build for the mpu and flash that... and that just runs endlessly along side the cpu and the cpu can talk to teh data being pulled from the mpu?
2020-05-03T21:12:46 < mawk> yeah something like that yes
2020-05-03T21:13:29 < Mangy_Dog> ok so the cpu sits along side the mpu... not directly programming it on the fly (unless i guess you made some hacky software that does it)

2020-05-03T21:15:34 < Thorn> Mangy_Dog cheaper than many h7 actually
2020-05-03T21:15:58 < mawk> you can probably program on the fly Mangy_Dog 
2020-05-03T21:16:05 < mawk> all mcu can run from RAM you know
2020-05-03T21:16:11 < mawk> just change the ram and direct the mcu to run fro it

2020-05-03T21:16:24 < mawk> that's how you can run code using a debugger also
2020-05-03T21:16:33 < mawk> or, that's how you can flash the flash from the progarm itself
2020-05-03T21:16:49 < mawk> you direct execution to the sram then you can mess with the flash; ST's HAL does this in some flash functions
2020-05-03T21:20:09 < Mangy_Dog> hmm
2020-05-03T21:20:13 < Mangy_Dog> fair
2020-05-03T21:20:28 < Mangy_Dog> i would argue the H7 is a far far far far far more powerful chip
2020-05-03T21:20:33 < mawk> why
2020-05-03T21:20:37 < Mangy_Dog> if youre on about allwinner chips

2020-05-03T21:20:54 < Mangy_Dog> :)
2020-05-03T21:20:59 < mawk> it's M7
2020-05-03T21:21:03 < mawk> some are dual mcus also
2020-05-03T21:21:10 < mawk> M7 + M4
2020-05-03T21:21:20 < Mangy_Dog> all winner h7 is something like a quad core 2ghz full soc :p
2020-05-03T21:21:46 < mawk> I see
2020-05-03T21:21:50 < Mangy_Dog> oh wait no
2020-05-03T21:21:54 < Mangy_Dog> it only goes up to h6

2020-05-03T21:22:56 < mawk> "dual tri-sesquiuno-octo-nonadecilia-SPI"
2020-05-03T21:23:16 < Mangy_Dog> just to make it more confusing
2020-05-03T21:27:18 < mawk> they went from parallel protocols to serial protocols and now back to parallel protocols"

2020-05-03T21:28:09 < Mangy_Dog> the mp1 basically roughly 10 dollars per chip... doesnt sound bad... Minimum order 10k D:
2020-05-03T21:30:29 < Thorn> Mangy_Dog add ddr3 ram, flash (a microsd socket as a minimum), pmic, minimum 6 layer pcb and you'll have a (pretty useless) breakout

2020-05-03T21:35:56 < Mangy_Dog> ive not used that
2020-05-03T21:36:07 < Mangy_Dog> kicad here and theres not a built in router any more and the addon is ........ not great
2020-05-03T21:45:20 < Thorn> wtf why does hyperlynx want over 9GB of space
2020-05-03T21:58:02 < Steffanx> Isnt space cheap in russia?
2020-05-03T21:58:31 < qyx> americans say soyuz is not that cheap
2020-05-03T21:58:54 < Steffanx> You can trust americans.
2020-05-03T22:00:21 < specing> soyuz is very expensive
2020-05-03T22:01:00 < specing> 70 mil / passenger, 3 passengers
2020-05-03T22:01:30 < specing> spacex probably won't be more than 200 mil total, 7 passengers. So 30 mil/passenger

2020-05-03T23:20:51 < ds2> are the motorbikes 2cycle or 4 cycle engines?
2020-05-03T23:21:08 < tomeaton17> or maybe gypsies

2020-05-03T23:21:35 < PaulFertser> Well, some enduro too.
2020-05-03T23:21:59 < ds2> was just curious...125cc seems small for 4cyc

2020-05-03T23:25:04 < Mangy_Dog> upi mean 4 stroke 2 stroke
2020-05-03T23:25:08 < PaulFertser> ds2: small displacement are all single cylinder.
2020-05-03T23:25:14 < Mangy_Dog> and yeah 125 is a single cylinder 4 stroke for road bikes
2020-05-03T23:25:32 < Mangy_Dog> usually limited to aroudn 12 hp
2020-05-03T23:26:38 < tomeaton17> probably because people understand the meaning and don't care about the pedantries
2020-05-03T23:27:09 < PaulFertser> Aprilia RS125 is a different beast
2020-05-03T23:28:42 < Mangy_Dog> yeah teh rs125 is a nice bike and i think after being unlimited can so about 20 to 20hp with some mods
2020-05-03T23:28:44 < Mangy_Dog> the 4 stroke
2020-05-03T23:28:49 < Mangy_Dog> the 2 stroke can do a bit more

2020-05-04T00:00:16 < Cracki> boss wants me to put completely new firmware code for a completely different board (successor design) in a *branch* of the repo. I think it's bad practice but can't think of good reasons why. help?
2020-05-04T00:01:18 < qyx> why should it be good?
2020-05-04T00:01:29 < qyx> do you plan to maintain both codebases?
2020-05-04T00:01:34 < qyx> do they share anything?
2020-05-04T00:01:39 < qyx> does they share history?
2020-05-04T00:01:40 < Cracki> no, the old one is not gonna be touched anymore
2020-05-04T00:02:39 < qyx> I would either make a new repo
2020-05-04T00:02:42 < Cracki> they share no history beside the name and purpose. new board is gonna replace old board in some devices, so it does the same there, but it's more capable and will do more elsewhere
2020-05-04T00:02:54 < Cracki> I would do a new repo too but he is asking for "just do a branch"
2020-05-04T00:03:21 < Cracki> I'm asking for good reasons why the branch is bad practice
2020-05-04T00:03:22 < qyx> or depending on the flow make changes, properly comment & commit reasons and make a release with a bumped major
2020-05-04T00:03:26 < PaulFertser> Some projects maintain their website in a branch, probably github makes it standard or some such.
2020-05-04T00:03:35 < PaulFertser> So it's not too silly probably?
2020-05-04T00:03:35 < Cracki> found one discussion on stackoverflow and they all say "eh whatever"
2020-05-04T00:03:55 < zyp> it's possible to have branches without common ancestors
2020-05-04T00:04:02 < mawk> yes I was about to say that ^
2020-05-04T00:04:06 < mawk> you can make an orphan branch
2020-05-04T00:04:11 < zyp> yeah
2020-05-04T00:04:15 < Cracki> I realize that
2020-05-04T00:04:15 < mawk> if it's orphan then why not
2020-05-04T00:04:18 < mawk> but I wouldn't do it still
2020-05-04T00:04:24 < qyx> technically possible yes, but if good practice or logical at all
2020-05-04T00:04:28 < mawk> people don't expect branches to have no common ancestor
2020-05-04T00:04:28 < zyp> and having multiple orphan branches is essentially the same as having a separate repo
2020-05-04T00:04:32 < mawk> just don't do it
2020-05-04T00:04:36 < zyp> just in the same repo
2020-05-04T00:04:38 < mawk> make a new repo
2020-05-04T00:04:51 < zyp> I mean, you can clone the repo with only one of the brances, then you've got a separate repo

2020-05-04T00:04:56 < qyx> if you do gitflow, there are strictly defined branches
2020-05-04T00:04:57 < Cracki> it still feels very much like abuse of a mechanism that is used to organize code that is ultimately *merged*
2020-05-04T00:04:58 < zyp> so it's moot anyway
2020-05-04T00:05:26 < zyp> you can store both branches in one repo on the server, have separate clones in your working copy
2020-05-04T00:05:34 < zyp> but yeah
2020-05-04T00:05:39 < Cracki> you guys haven't given me reasons, you just confirm what I want to do, i.e. new repo
2020-05-04T00:05:42 < PaulFertser> Similar purpose for the new project might mean that firmware developer would be using old version for the reference so it might be even beneficial to have it both cloned by a single command.
2020-05-04T00:05:50 < zyp> the main problem is that it's messy
2020-05-04T00:06:12 < Cracki> the new code is already at feature parity with the old shit
2020-05-04T00:06:29 < Cracki> all the major ICs are different too
2020-05-04T00:06:32 < zyp> if you have two products that both have a current firmware, where do you find that? I'd expect it to be tip of master in each of two repos
2020-05-04T00:06:38 < mawk> the reason to favor new repo over orphan branch Cracki is purely aesthetic
2020-05-04T00:06:40 < zyp> you can't call both master if you put them in the same repo
2020-05-04T00:06:47 < mawk> the reason to favor new repo over *merged* branch is something else
2020-05-04T00:06:51 < mawk> the latter is just horrible
2020-05-04T00:06:55 < PaulFertser> The main reason would be that it's too unconventional and hence possibly confusing to do what he proposes.
2020-05-04T00:07:08 < zyp> and you get a ton of other potential tag/branchname conflicts as well
2020-05-04T00:07:25 < Cracki> thx, I'll take "unconventional and confusing". he's an engineer, I hope he'll understand that.
2020-05-04T00:07:48 < Cracki> I fucking hate repos where the real shit is hidden in some branch that isn't master
2020-05-04T00:08:00 < mawk> you can change the fetch_head so that the default branch is not master
2020-05-04T00:08:00 < Cracki> it's like a fucking egg hunt
2020-05-04T00:08:05 < mawk> but you can have only one such head

2020-05-04T00:08:43 < qyx> Cracki: whats the reason he asks, monthly fees for the new repo? :X
2020-05-04T00:08:43 < Cracki> recently I was a newbie in some project and they just gave me the fucking repo, and I wondered why master branch had nothing of note in it
2020-05-04T00:08:52 < Cracki> no, he just seems to be lazy
2020-05-04T00:09:30 < Cracki> he's using redmine and I think it doesn't automagically create a repo for a new project so he would have to engage someone to do it for him
2020-05-04T00:09:49 < Cracki> I'm just a programmr, I don't get to have "administrative" access to that stuff :P
2020-05-04T00:09:56 < mawk> it's using git ?
2020-05-04T00:09:59 < Cracki> git
2020-05-04T00:10:13 < mawk> tell him he's a dirty git
2020-05-04T00:10:32 < Cracki> >_>
2020-05-04T00:10:34 < qyx> kybel gitu
2020-05-04T00:10:37 < qyx> PaulFertser may understand
2020-05-04T00:10:51 < mawk> I had a fight with my boss
2020-05-04T00:10:53 < mawk> over distros
2020-05-04T00:10:55 < mawk> lol
2020-05-04T00:11:01 < mawk> I was trying to defend debian, and he was using stupid arguments
2020-05-04T00:11:11 < qyx> like
2020-05-04T00:11:14 < mawk> "it's shit because 10 years ago an 'apt upgrade' failed on my home server"
2020-05-04T00:11:55 < zyp> mawk, what's the point of even engaging? you can't get anything productive from that
2020-05-04T00:12:03 < mawk> it's in my personality
2020-05-04T00:12:05 < Cracki> I could tolerate just both code bases side by side in different directories... eh I'll suggest it
2020-05-04T00:12:05 < mawk> I have to win debates
2020-05-04T00:12:20 < Cracki> so what does he want to use?
2020-05-04T00:12:22 < zyp> Cracki, uh, that sounds worse
2020-05-04T00:12:43 < mawk> why would you do that Cracki ?
2020-05-04T00:12:46 < mawk> a branch is for one codebase
2020-05-04T00:12:46 < zyp> unless they are actually going to get maintained in parallel
2020-05-04T00:13:04 < Cracki> if you're gonna be messy, be real messy.
2020-05-04T00:13:12 < mawk> otherwise you don't know which commits are refering to which codebase, unless you use like prefixes in commit messages which are not even enforced without custom hooks 
2020-05-04T00:13:20 < mawk> and even then there's no builtn support to filter on such prefixes
2020-05-04T00:13:25 < mawk> it's just not made for it
2020-05-04T00:13:25 < zyp> I mean, I keep all my workstuff firmware in one repo
2020-05-04T00:13:42 < mawk> also a new repo is just free, unless he's getting ripped off by some enterprisey repo thing
2020-05-04T00:13:46 < zyp> but it's building on a common codebase
2020-05-04T00:13:48 < Cracki> his problem is he doesn't want to create a new project or a new repo. and my problem is branches for different code is yuck. so the solution is new code beside old code in same branch.
2020-05-04T00:13:57 < Cracki> (there is only one branch there anyway)
2020-05-04T00:14:36 < Cracki> he's getting ripped off by not knowing how to give a redmine project a repo
2020-05-04T00:14:49 < zyp> I've got two different boards, they have different roles and therefore different IO, but they use the same microcontroller and network circuitry, so the base platform is the same
2020-05-04T00:14:59 < Cracki> makes sense
2020-05-04T00:15:19 < Cracki> this is what he doesn't do himself: https://www.redmine.org/projects/redmine/wiki/RedmineRepositories
2020-05-04T00:15:40 < mawk> then I'd use a submodule for the common code zyp 
2020-05-04T00:15:48 < mawk> and that way you can check out differnet versions of the common code for the two projects
2020-05-04T00:15:53 < mawk> or have custom patches on top of it
2020-05-04T00:16:03 < mawk> that's what it's made for
2020-05-04T00:16:24 < zyp> I'm actually building six .elfs from the same codebase; application, bootloader and ssloader (which is a bootloader that loads like application to allow updating the actual bootloader)
2020-05-04T00:16:36 < mawk> ah
2020-05-04T00:16:41 < mawk> so with #ifdef in the code and all ?
2020-05-04T00:16:43 < zyp> it's split into modules where some builds for all targets and some builds for only some targets
2020-05-04T00:17:06 < zyp> some stuff is ifdeffed and some stuff is a matter of including/excluding a whole directory
2020-05-04T00:17:11 < mawk> I see
2020-05-04T00:17:18 < mawk> yeah it maybe makes sense in a single repo then
2020-05-04T00:18:31 < zyp> I generally like submodules and were planning that in the beginning, but when the time came to restructure the repo, I concluded it was tightly enough coupled that it made sense to keep it all together instead
2020-05-04T00:19:03 < zyp> might reconsider in the future as the project grows
2020-05-04T00:19:57 < zyp> I already have one submodule; I'm autogenerating a bunch of parameter handling code from a set of parameter definition files in a separate submodule
2020-05-04T00:20:17 < zyp> and I load the same submodule in the parameter gui util so it can navigate the parameters

2020-05-04T00:55:17 < qyx> hah, documentation states that a smbus command requires the word protocol to read it

2020-05-04T05:09:59 < aandrew> hm, nordic ble shit has changed (again) since I used it last
2020-05-04T05:10:10 < aandrew> now you're supposed to register SDH_OBSERVER shit so the BLE stack calls you
2020-05-04T05:35:10 < Spirit532> so I have another weird issue
2020-05-04T05:35:19 < Spirit532> I've configured my timer to generate PWM&PWMN
2020-05-04T05:35:31 < Spirit532> but I'm only getting output on the PWMN channels
2020-05-04T05:35:38 < Spirit532> it's correct output, but... ???
2020-05-04T05:36:21 < Spirit532> https://i.spirit.re/p2crM.png
2020-05-04T05:36:37 < Spirit532> BRK is disabled, pulse on compare too
2020-05-04T05:36:45 < Spirit532> all 3 channels are set identically
2020-05-04T05:38:55 < Cracki> did ya config the gpios too
2020-05-04T05:39:17 < Cracki> are you sure you want chx and chxN polarity to be the same

2020-05-04T05:40:01 < Spirit532> gpios are autoconfigured

2020-05-04T05:40:41 < Cracki> ok then what would cause the negated outputs to show something but not the positive ones?
2020-05-04T05:40:56 < Spirit532> that's my question
2020-05-04T05:41:08 < Cracki> show gpio settings tab for that timer

2020-05-04T05:42:57 < Spirit532> that's my question...
2020-05-04T05:43:20 < Cracki> did you config power and clock to those I/O ports?
2020-05-04T05:43:34 < Cracki> cubemx generates this code, but it may have forgotten for those pins
2020-05-04T05:43:38 < Spirit532> ... doesn't cube do that
2020-05-04T05:43:52 < Cracki> port A is the positive signals, port b has all the negative ones
2020-05-04T05:43:54 < Cracki> check that
2020-05-04T05:45:10 < Spirit532>   __HAL_RCC_GPIOA_CLK_ENABLE();
2020-05-04T05:45:10 < Spirit532>   __HAL_RCC_GPIOB_CLK_ENABLE();
2020-05-04T05:45:13 < Spirit532> this is there
2020-05-04T05:45:16 < Cracki> hm ok
2020-05-04T05:46:14 < Cracki> bad soldering?
2020-05-04T05:46:41 < Spirit532> checked at MCU
2020-05-04T05:46:43 < Cracki> just fuck with the settings of that timer randomly
2020-05-04T05:47:06 < Cracki> checked? meaning you can move those pins as gpio?
2020-05-04T05:47:27 < Spirit532> let me see
2020-05-04T05:49:12 < Spirit532> twiddling the pin works
2020-05-04T05:50:03 < Spirit532> but not with the fucking timer
2020-05-04T05:50:07 < Cracki> great, that's excluded
2020-05-04T05:50:18 < Cracki> ok now I'd try some other modes of that timer
2020-05-04T05:50:51 < Cracki> set up some fixed interval and compares you can measure with multimeter/scope

2020-05-04T05:51:24 < Cracki> not using that complementary fuckery yet. some basic mode has to work
2020-05-04T05:51:27 < Spirit532> PWM mode 1 is set on compare match
2020-05-04T05:51:31 < Spirit532> 2 is clear on compare match
2020-05-04T05:51:33 < Spirit532> so that won't help
2020-05-04T05:51:38 < Cracki> why
2020-05-04T05:51:47 < Cracki> that ought to give you simple pwm
2020-05-04T05:52:21 < Cracki> it'll reset the pin to the other state on reload
2020-05-04T05:52:29 < Spirit532> I mean it's just going to invert the signal
2020-05-04T05:52:40 < Cracki> if it does, you get a 50% dc but you get it wiggling
2020-05-04T05:53:07 < Cracki> the question I would pursue now is whether the timer can wiggle every one of those pins
2020-05-04T05:53:33 < Spirit532> well, it is a standard PWM/PWMN channel
2020-05-04T05:53:38 < Spirit532> so I don't know why it wouldn't
2020-05-04T05:54:20 < Spirit532> yeah, setting mode to 2 just flips which pins are broken
2020-05-04T05:54:25 < Spirit532> now PWMN is not working
2020-05-04T05:54:38 < Cracki> lol wat changed
2020-05-04T05:54:45 < Spirit532> nothing except that
2020-05-04T05:55:02 < Spirit532> I set pwm from mode 1 to mode 2 on each channel, PWM1-2-3 work, PWMN1-2-3 don't
2020-05-04T05:55:10 < Cracki> that's progress
2020-05-04T05:55:13 < Cracki> and a pattern
2020-05-04T05:55:23 < Cracki> now fuck with some more settings :D
2020-05-04T05:55:26 < Cracki> the technical term is fuzzing
2020-05-04T05:55:39 < Spirit532> fuzzing my own hardware lol
2020-05-04T05:55:50 < Cracki> maybe those things want their polarity different
2020-05-04T05:59:07 < Spirit532> fixed it
2020-05-04T05:59:09 < Spirit532> dunno how
2020-05-04T05:59:14 < Cracki> git commit, git diff :D

2020-05-04T05:59:26 < Cracki> if cubemx would stop reordering its ioc contents randomly

2020-05-04T12:54:27 < dongs> how about pin swapping?
2020-05-04T12:54:38 < dongs> i always jsut manually do it, i wonder how much easier it is to do audio
2020-05-04T12:54:40 < dongs> er auto
2020-05-04T12:57:19 < zyp> you need to configure which pins can be swapped, and then depending on the mode you choose it might mess up your schematic
2020-05-04T12:59:18 < zyp> «When the changes are merged into the schematics there are two ways that a pin swap can be handled, either by swapping the pins on the component symbol, or by swapping net labels on the wires attached to the pins.»

2020-05-04T13:01:57 < dongs> yeah i jsut did some setup on a stm32 , it looks too ahrd
2020-05-04T13:02:05 < dongs> i just manually do it while routing
2020-05-04T13:02:09 < zyp> same
2020-05-04T13:02:49 < zyp> I mean, the thing about microcontrollers is that you generally can swap pins, but not freely for stuff that's using AF
2020-05-04T13:03:10 < dongs> https://i.imgur.com/EqHNBzQ.png i marked all GPIO that isnt AF as swappable
2020-05-04T13:03:14 < zyp> you could swap one uart tx with another, but not some arbitrary shit
2020-05-04T13:03:15 < dongs> but its only showing like half of the stuff
2020-05-04T13:03:20 < dongs> seems to be only doing unrouted pins
2020-05-04T13:03:31 < dongs> or maybe depends on some other criteria
2020-05-04T13:04:06 < zyp> not worth spending too much time on when you can do it faster by hand

2020-05-04T14:09:08 < karlp> man, making a setup with a ntp server that is stepping time back and forth is much more hassle than I expected :)
2020-05-04T14:09:54 < karlp> and now, despite putting this damn thing a in container, my local pc has chosen this pseudo fake ntp server as valid and using it's time..
2020-05-04T14:11:46 < karlp> blah, looks like running "date -s" in the docker container has set my host's clock too.
2020-05-04T14:17:20 < BrainDamage> despite the common misconception, containers provide little isolation in terms of permissions
2020-05-04T14:17:27 < BrainDamage> or at least, docker does

2020-05-04T18:13:44 < jadew> so what are some good < $500/ever alternatives to fusion360?
2020-05-04T18:14:11 < jpa-> freecad! ;)
2020-05-04T18:14:37 < jadew> jpa-, I haven't used it in a while, but when I did, I didn't like it
2020-05-04T18:14:45 < karlp> guess you're paying then...
2020-05-04T18:14:45 < jpa-> you can spend the $500 on therapy to recover from the experience
2020-05-04T18:15:07 < jadew> karlp, you're using freecad?
2020-05-04T18:15:26 < jadew> I haven't used it in maybe 5 years, so... who knows, could be good now
2020-05-04T18:15:28 < karlp> I wouldn't say my usage of it is relevant.
2020-05-04T18:15:34 < karlp> I'm not a mech person _at all_
2020-05-04T18:15:42 < jpa-> i use it often, it is not good
2020-05-04T18:15:44 < karlp> and I have no experience with anything pro either.
2020-05-04T18:15:56 < jadew> well, you could use it for 3d prints
2020-05-04T18:16:02 < jadew> jpa-, good to know, thanks
2020-05-04T18:16:25 < jadew> someone recommended turbocad a year or so ago, I think I'll give that a try

2020-05-04T18:17:03 < jadew> the 2D/3D thing seems to be $200, so within the budget
2020-05-04T18:17:46 < jadew> the interface reminds me of early autocad
2020-05-04T18:18:52 < Cracki> if you don't like freecad or blender, your choice is effectively limited to commercial software. autodesk has fusion and inventor, there's solidworks, catia, creo, ...
2020-05-04T18:19:24 < jadew> Cracki, well, I don't mind commercial, I just don't want to pay a shitload of money yearly
2020-05-04T18:19:43 < zyp> depending on what you're planning to use it for, maybe openscad could work?
2020-05-04T18:19:59 < jadew> zyp, already been down that route, it's ok for very simple things
2020-05-04T18:20:23 < jadew> once your design gets a little more complex, you're just wasting your time
2020-05-04T18:20:48 < jpa-> for pro stuff, not getting STEP out of it hurts a lot also
2020-05-04T18:20:54 < Cracki> openscad takes a moment to "compile" things. that's like "compiling" your text document (latex), an idea from the 60s when everyone was stoned and didn't expect any better
2020-05-04T18:21:54 < Cracki> whatever data structures and algorithms underlie it, nobody seems to dare improve them
2020-05-04T18:22:32 < karlp> so markup is a stoner 60s idea that's dumb? wat?
2020-05-04T18:22:37 < Cracki> commercial software doesn't even blink at comparable object complexity

2020-05-04T18:23:13 < jadew> that's not what the big difference is
2020-05-04T18:23:41 < Cracki> yes, the diff is you can't manipulate things visually, you have to express your thought as math
2020-05-04T18:23:41 < jadew> it's the fact that there are no easy chamfers, fillets, threads
2020-05-04T18:23:58 < Cracki> and that :>
2020-05-04T18:24:23 < jadew> I don't mind a bit of math, but ffs, if you want to do a chamfer on a box, you have to model the freaking chamfer and take the difference
2020-05-04T18:24:48 < Cracki> hm well fusion can model threads, but for inventor I remember I had to use a plugin that was recommended in the support forum. maybe they've copied that feature into inventor by now
2020-05-04T18:25:11 < zyp> isn't fusion supposed to be inventor light?
2020-05-04T18:25:16 < jadew> well, tbf the modeling of threads is only useful for 3d printing, but still...
2020-05-04T18:25:19 < zyp> I'd expect inventor to be able to do anything fusion can
2020-05-04T18:25:36 < Cracki> yes but the code bases only overlap _some_

2020-05-04T18:27:45 < jpa-> yeah, need specifying tolerances and hope the CAM tool smooths out the polygons instead of making them worse

2020-05-04T18:57:49 < Cracki> I tried freecad before and after I got into autodesk inventor (openscad was first tho). before, freecad made no sense and their docs didn't help at all. after I learned the interaction basics from the original, i suddenly saw what they were trying to emulate, and I could kinda grasp how freecad needed to be touched.

2020-05-04T19:15:31 < logicp> I've been trying to receive data via USART interrupts on my STM32F031K6 (nucleo 32), and I'm making two observations for which I have no explanation
2020-05-04T19:15:48 < logicp> 1. Calling NVIC_EnableIRQ causes the interrupt handler to be called
2020-05-04T19:16:04 < logicp> 2. The interrupt handler is never called again
2020-05-04T19:16:24 < logicp> I'm calling NVIC_EnableIRQ before the while loop of my program: https://github.com/adventurist/STMF031K6_USART_Interrupt/blob/3de29cc2b270bc1a4a16e4155755f4bf1fbe335d/Core/Src/main.c#L94
2020-05-04T19:16:33 < logicp> Does anyone have any ideas as to what I might be doing wrong?
2020-05-04T19:16:42 < logicp> I've attempted to avoid using the HAL libraries as much as possible
2020-05-04T19:17:01 < zyp> it's not getting stuck in the interrupt handler, it's actually executing the rest of the code otherwise?
2020-05-04T19:18:33 < logicp> yes, I can verify that because 1. The interrupt handler turns on an LED and 2. My while loop checks if the LED is on, and then turns it off after a small delay

2020-05-04T19:22:47 < zyp> logicp, well, you're configuring BRR wrong, so it never triggering is probably because you're not configuring the baudrate correctly
2020-05-04T19:26:06 < zyp> as far as I can see, you're effectively configuring it to 5859 baud
2020-05-04T19:28:07 < zyp> what you probably want to do is BRR = 48000000 / 9600;

2020-05-04T19:47:09 < Steffanx> Thats why I usually try to send something first. To check if the baudrate is right and the (part of) the pin config
2020-05-04T19:47:50 < logicp> good idea
2020-05-04T19:47:56 < zyp> yeah, sending is generally a simpler test

2020-05-04T21:09:46 < Steffanx> I liked it, except for this (i think tiny mistake @ 2.54-2.55). One of the notes is off.
2020-05-04T21:10:40 < kakibull> yes
2020-05-04T21:15:55 < jadew> you know what the kicker is? while he's playing that for the audience, he's listening to better music in his headphones
2020-05-04T21:16:17 < jadew> I think it's disrespectful.

2020-05-04T21:23:20 < jadew> heh
2020-05-04T21:25:44 < Thorn> is 4 layers better for BLE than 2? the layout is simple and the bottom ground is almost continuous
2020-05-04T21:26:04 < kakibull> antenna?
2020-05-04T21:26:32 < kakibull> if your pcb has rf on it
2020-05-04T21:26:32 < jpa-> Thorn: using a chip + separate antenna, or using a module with integrated antenna?
2020-05-04T21:26:53 < Thorn> chip + pcb antenna
2020-05-04T21:26:54 < kakibull> if your pcb has RF on it you simply go with 4layer minimum
2020-05-04T21:27:02 < Thorn> copied from the DK
2020-05-04T21:27:15 < jpa-> is the DK two-layer design?
2020-05-04T21:27:21 < Thorn> nope, 4
2020-05-04T21:27:24 < jpa-> the antenna parameters will change a lot depending on the pcb layer count
2020-05-04T21:27:41 < kakibull> and if you are not quite sure why they use 4layer - you use 4layer
2020-05-04T21:27:43 < jpa-> (it will also change by the stackup of the 4-layer board)
2020-05-04T21:28:31 < jadew> why do they use 4 layers?
2020-05-04T21:28:33 < kakibull> there is rf basic video in tubes
2020-05-04T21:28:43 < jpa-> but on the other hand, just throwing a copied pcb antenna design on a board will end up with a mistuned antenna anyway, so it might work just as well on 2-layer board as it would on 4-layer board, that is, crappily
2020-05-04T21:28:59 < kakibull> first rule is you use 4layer board if you don't know exactly what you are doing
2020-05-04T21:29:20 < jadew> so they don't know what they're doing? :)
2020-05-04T21:29:33 < jadew> :P
2020-05-04T21:29:42 < jpa-> what kaki is saying has some truth to it - controlled impedances on two layer boards is a bit of a hit-or-miss because the dielectric is so thick and you need such wide traces
2020-05-04T21:29:49 < kakibull> or it's just easier to get desing done in 4layer anyway
2020-05-04T21:30:07 < kakibull> like 3mm wide
2020-05-04T21:30:10 < jadew> in fact, it's much easier to get controlled impedance on thick dielectrics
2020-05-04T21:30:12 < Thorn> jadew: the routing is complicated, they have several switch ICs that switch between onboard peripherals and ardweeno connectors when a "shield" is detected
2020-05-04T21:30:29 < jadew> because the variation in trace width has a lower effect on impedance
2020-05-04T21:30:43 < jadew> also the Dk of the dielectric
2020-05-04T21:30:43 < jpa-> jadew: but the variation of the dielectric has a higher effect
2020-05-04T21:31:12 < jpa-> (or rather, the variation of the whole stack matters, instead of just the one between the top two layers)
2020-05-04T21:31:15 < jadew> yeah, but it gets worse on thinner substrates
2020-05-04T21:31:25 < Thorn> the antenna is Г shaped and it sits in a wide gnd cutout on all layers
2020-05-04T21:31:53 < Thorn> will it really change impedance so much when inner layers are removed?
2020-05-04T21:32:14 < Thorn> anyway I'll look for app notes and guidelines
2020-05-04T21:32:36 < jadew> if the antenna is just a piece of wire, then the 4-layer thing is not about the antenna
2020-05-04T21:32:40 < jadew> it must be about the layout
2020-05-04T21:33:11 < jpa-> might be simple & robust enough antenna design that it is not that sensitive to parameters
2020-05-04T21:33:50 < jadew> yeah
2020-05-04T21:34:42 < Thorn> the antenna is a trace
2020-05-04T21:35:22 < Thorn> https://infocenter.nordicsemi.com/topic/ug_nrf52832_dk/UG/nrf52_DK/images/nrf52_dk_kit_content.png
2020-05-04T21:35:36 < Thorn> it's under the silkscreen crap on the right
2020-05-04T21:36:08 < jadew> yeah, so basically a piece of wire
2020-05-04T21:36:15 < Thorn> let me take a screenshot from altium
2020-05-04T21:36:16 < jpa-> the ground planes are close enough that they probably affect the antenna, but hard to tell how much
2020-05-04T21:36:46 < jpa-> after all 2.4GHz wavelength is ~120mm and that is like 5mm away
2020-05-04T21:37:11 < jadew> I don't know much about antennas, but it's possible that it is that shape because that's the minimum distance it needs from the ground plane to function properly
2020-05-04T21:38:03 < jpa-> yeah, those microstrip L-antennas need to be specific distance from the ground plane - but i'm not sure if the number of layers in the ground plane matters
2020-05-04T21:38:14 < jpa-> you definitely should have a ground plane at least on the same side as the antenna
2020-05-04T21:38:50 < Thorn> https://i.imgur.com/uYStTxO.png
2020-05-04T21:39:22 < Thorn> I will have that
2020-05-04T21:39:35 < jadew> how long is it in total?
2020-05-04T21:40:56 < Thorn> horizontal distance between the edge of gnd planes and the trace is 5mm. total length is 22.7mm
2020-05-04T21:41:18 < jadew> that's long
2020-05-04T21:41:46 < jadew> 1/4 of the wavelength would be 31mm
2020-05-04T21:42:07 < zyp> I don't think number of layers matter
2020-05-04T21:42:14 < jadew> they don't
2020-05-04T21:42:17 < zyp> (in a significant manner)
2020-05-04T21:42:28 < jadew> and the thickness of the board doesn't matter much either
2020-05-04T21:42:28 < zyp> ground plane size/shape does though
2020-05-04T21:42:39 < qyx> such antena, I did a similar one
2020-05-04T21:42:43 < qyx> never tested it
2020-05-04T21:42:46 < jadew> it's obviously taken into account, but it won't affect it too much

2020-05-04T21:55:55 < kakibull> answer is maybe
2020-05-04T21:56:06 < kakibull> see if anyone has done it

2020-05-04T21:57:22 < Thorn> how do you  use a VNA to match an antenna anyway? the output impedance of the radio chip is unknown (unless I'm missing something)
2020-05-04T21:57:38 < jadew> you can measure that too

2020-05-04T21:58:09 < Thorn> or do you use the chip to generate a carrier?
2020-05-04T21:58:14 < Thorn> what is the procedure
2020-05-04T21:58:49 < Thorn> "instead of the chip" == with the chip not mounted
2020-05-04T21:58:49 < jadew> you test the S11 while its operating
2020-05-04T21:59:17 < jadew> ideally you would want it to be quiet but working
2020-05-04T21:59:21 < jadew> as in... powered on
2020-05-04T21:59:57 < jadew> and you connect the VNA on its output
2020-05-04T22:02:00 < jadew> you wouldn't do it on that board tho, you have to make a test board specifically for this
2020-05-04T22:02:34 < Thorn> and sweep the TX frequency?
2020-05-04T22:02:39 < jadew> yeah
2020-05-04T22:02:58 < jadew> that connector there tho - that might actually spare you another board
2020-05-04T22:03:05 < jadew> you can just cut off the antenna with a cutter
2020-05-04T22:03:15 < jadew> and use that to test both the chip and the antenna

2020-05-04T22:04:31 < Thorn> so both the chip and the VNA are transmitting?

2020-05-04T22:05:31 < jadew> I don't really know how that is done in cases like this, but I think you just have to make sure the test power is higher than the output power from the device
2020-05-04T22:06:01 < jadew> and you probably get to calculate the uncertainty in the measurement based on that, or you can just take multiple measurements and average them

2020-05-04T22:09:15 < jadew> yeah, that really looks like an elegant solution
2020-05-04T22:09:32 < BrainDamage> you can use it two way, cut the antenna side or cut the chip side
2020-05-04T22:09:38 < BrainDamage> so you can measure both
2020-05-04T22:09:39 < jadew> yup
2020-05-04T22:09:55 < Thorn> and in order to measure the output impedance of the chip you cut the antenna and measure S22?

2020-05-04T22:13:14 < BrainDamage> if it's for the chip, after, if it's for the antenna, before
2020-05-04T22:13:37 < BrainDamage> after the matching network I mean
2020-05-04T22:13:39 < Thorn> it's to match one to the other lol
2020-05-04T22:13:47 < BrainDamage> oh, then add two
2020-05-04T22:14:13 < BrainDamage> ideally you want to measure separately matching network, antenna, and chip

2020-05-05T00:09:15 < zyp> Thorn, here's how I hooked up VNA to my NFC antenna: https://bin.jvnv.net/file/uNgNm.JPG
2020-05-05T00:09:42 < zyp> just cut the traces between the chip and the inductors and hooked up the VNA
2020-05-05T00:11:02 < Thorn> ok and what then? measure S11, try to make it... what? is the output Z of the chip known?
2020-05-05T00:11:15 < zyp> idk why jadew wants the chip in parallel with the VNA, as far as I remember from uni we learned to hook up the VNA at the point that's defined to be 50ohm impedance
2020-05-05T00:11:58 < Thorn> so you assume the Zout of that chip is 50 + j0 Ω?
2020-05-05T00:12:04 -!- bitmask [~bitmask@c-73-215-237-27.hsd1.nj.comcast.net] has joined ##stm32
2020-05-05T00:12:07 < zyp> IME either the chip has a 50ohm antenna terminal, or specs some passives that'll give you a 50 ohm reference point
2020-05-05T00:12:40 < Thorn> ok let me reread the noridc runes
2020-05-05T00:12:46 < zyp> and then antenna matching goes between that point and the antenna, so you'll want to measure S11 from that point towards the antenna
2020-05-05T00:13:04 < strata> lol @ the nordic runes
2020-05-05T00:14:21 < zyp> https://bin.jvnv.net/file/cN8Zp.jpg <- IIRC on this thing the 50ohm point was either between L3 and C23 or between C23 and antenna
2020-05-05T00:14:31 < Thorn> there's 2 kinds of radio chips btw, some have separate in & out while others have a common RF pin
2020-05-05T00:14:45 < zyp> we tuned that one by simply extending the length of the antenna a bit
2020-05-05T00:14:45 < Thorn> si4463 is the former, nrf is the latter
2020-05-05T00:14:57 < zyp> yes
2020-05-05T00:15:07 < zyp> the nfc chip in my other photo is also the former
2020-05-05T00:15:17 < zyp> I think I left the inputs connected, cut the outputs
2020-05-05T00:15:22 < zyp> idk if that's the right thing to do
2020-05-05T00:16:40 < zyp> but either way, everything gets a lot easier if you can split the circuit into a 50-ohm-matched antenna and a 50-ohm-matched radio
2020-05-05T00:17:29 < Thorn> btw I've just read that if the gnd plane is < 1/4 wavelength then the coax becomes ground and alters measurements
2020-05-05T00:18:01 < Thorn> who came up with this electromagnetism crap
2020-05-05T00:18:09 < zyp> coax? aren't you doing radio and antenna on the same board?
2020-05-05T00:18:23 < Thorn> the one you use to hook up the vna
2020-05-05T00:19:01 < zyp> ah, right
2020-05-05T00:19:28 < zyp> I think in uni we clippd some ferrites around the coax
2020-05-05T00:19:55 < zyp> don't remember if it was to counteract that or something else

2020-05-05T00:21:46 < zyp> for frequency tuning, I feel return loss is the most intuitive plot to look at
2020-05-05T00:21:49 < zyp> https://bin.jvnv.net/file/wobo6.jpg
2020-05-05T00:22:00 < zyp> that's some random wlan antenna hooked to the VNA
2020-05-05T00:23:15 < zyp> return loss tells you how much of the energy is reflected back from the antenna
2020-05-05T00:23:43 < zyp> radiated energy is «lost»
2020-05-05T00:24:46 < zyp> so assuming it's not getting absorbed anywhere and dissipated as heat, it's a measure of radiated energy over frequency
2020-05-05T00:25:40 < Thorn> when do you need a return loss bridge btw?
2020-05-05T00:25:56 < zyp> what's a return loss bridge?
2020-05-05T00:28:58 < Thorn> I assume you don't need one when using a VNA?
2020-05-05T00:29:17 < Thorn> >A return loss bridge is often used together with a spectrum analyser with tracking generator.
2020-05-05T00:33:13 < zyp> ah, no, when doing S11 measurements the VNA itself is both outputting and measuring on the same port
2020-05-05T00:35:56 < Thorn> so it's got a builtin directional coupler basically?
2020-05-05T00:36:20 < zyp> I guess so
2020-05-05T00:37:18 < zyp> I'm not really an expert on this stuff, I've just done it a couple of times with satisfactory results, so I assume I'm doing something right :p

2020-05-05T00:50:37 < BrainDamage> Thorn: if your VNA can measure S11 it means it has builtin directional coupler / circolator, so you don't need that
2020-05-05T00:51:11 < BrainDamage> you need that device to redirect the reflected wave if your source cannot do measurements
2020-05-05T00:51:19 < Thorn> >your VNA
2020-05-05T00:52:11 < Thorn> okic thanks

2020-05-05T01:42:36 < Laurenceb> nvm I worked it out
2020-05-05T01:42:49 < Laurenceb> we was getting confused by shock wave equations
2020-05-05T01:43:38 < Laurenceb> I managed to get a conflicting result by imagining a bubble of air passing through the shock - it would only heat due to the pressure increase and adiabatic compression
2020-05-05T01:43:45 < Steffanx> Lol. You expected him to read your mind first?
2020-05-05T01:43:57 < Laurenceb> but I forgot that it would still be moving - the ke going into more heat

2020-05-05T10:51:46 < con3> anyone here know of any good resources on control theory and implementation using mcu's?
2020-05-05T11:01:04 < Cracki> numerics for a PID controller, or the real tough shit they teach to EE students?
2020-05-05T11:02:20 < Cracki> I'm sure DSP (FIR, IIR, decimation, ... ) would be useful too but it's not quite laplace space and "moving poles and zeros"
2020-05-05T11:05:07 < Cracki> someone linked "fundamentals of control theory" by brian douglas
2020-05-05T11:05:15 < Cracki> so that's probably useful
2020-05-05T11:05:33 < Cracki> videos on yt, a pdf exists too

2020-05-05T12:18:35 < jadew> it's so different from fusion...
2020-05-05T12:18:55 < jadew> lots of unneeded complexity
2020-05-05T12:22:00 < ds2> jadew: I was just wondering why you are using a dev license... slightly older stuff are included in magazine give aways, etc
2020-05-05T12:22:46 < jadew> ds2, I have to say, I find it a lot more difficult to use so far
2020-05-05T12:23:19 < jadew> for example, it seems to me like I have to create drawings that are continuous lines in order to extrude them
2020-05-05T12:23:41 < jadew> you can have have a circle inscribed in a square and just select one profile that
2020-05-05T12:23:45 < jadew> that's generated by that
2020-05-05T12:23:51 < jadew> instead you have to cut the circle
2020-05-05T12:23:55 < jadew> and the square
2020-05-05T12:23:58 < ds2> thought you wanted to use it for 2d stuff
2020-05-05T12:24:03 < ds2> 3D sucks in TCad
2020-05-05T12:24:09 < jadew> and then join the lines together 
2020-05-05T12:24:18 < jadew> ah, maybe that's what I wanted back then, yeah
2020-05-05T12:24:20 < jadew> it's possible
2020-05-05T12:24:31 < ds2> alibre is the most reasonably priced 3D package 
2020-05-05T12:24:44 < jadew> I'll check it out, thanks
2020-05-05T12:25:05 < ds2> works like the big packages - I have played with Solidworks and MasterCAM
2020-05-05T12:25:58 < jadew> they don't sell to my location
2020-05-05T12:26:00 < jadew> wtf...
2020-05-05T12:26:22 < Cracki> maybe they don't know romania is a market yet
2020-05-05T12:26:22 < ds2> doh
2020-05-05T12:26:26 < jadew> I have to go through a romanian distributor
2020-05-05T12:26:33 < jadew> haha Cracki 
2020-05-05T12:26:41 < Cracki> what is the point of distributors for software anyway
2020-05-05T12:27:00 < Cracki> weapons import/export restrictions because crypto library somewhere?
2020-05-05T12:27:04 < ds2> probally legal compliance
2020-05-05T12:27:16 < Cracki> fucking stupid
2020-05-05T12:27:30 < jadew> yeah, it's silly
2020-05-05T12:27:48 < Cracki> alibre has one reseller in romania. at least.
2020-05-05T12:27:50 < jadew> looks like it costs between 900 and 1600 EUR
2020-05-05T12:28:03 < jadew> which is above my 500 EUR budget
2020-05-05T12:28:19 < ds2> wow
2020-05-05T12:28:20 < Cracki> they market themselves to "hobbyists" but that's a reduced feature set ofc
2020-05-05T12:28:36 < ds2> even the smallest version?
2020-05-05T12:28:37 < jadew> ds2, how much did you pay for it?
2020-05-05T12:28:49 < jadew> ds2, that's what the romanian site says
2020-05-05T12:28:55 < jadew> between 915 and 1600 EUR
2020-05-05T12:28:57 < ds2> IIRC - about $900USD
2020-05-05T12:29:27 < ds2> that's for the middle version at that time
2020-05-05T12:29:38 < Cracki> atom 3d is 1xx euros for me
2020-05-05T12:29:40 < jadew> I see
2020-05-05T12:29:56 < ds2> i wanted the sheetmetal stuff which I never used
2020-05-05T12:30:04 < ds2> also wanted the exports
2020-05-05T12:30:04 < Cracki> https://alibre.info/alibre-preisliste.html not sure what they mean by "mit/ohne SW"
2020-05-05T12:30:25 < ds2> it was $99USD at one point
2020-05-05T12:30:29 < Cracki> ah, software maintenance = SW
2020-05-05T12:31:30 < jadew> I guess I'll have to give FreeCAD a serious try
2020-05-05T12:31:36 < jadew> maybe I can make it work
2020-05-05T12:33:10 < Cracki> what are you up to?
2020-05-05T12:33:35 < jadew> general stuff
2020-05-05T12:33:43 < jadew> enclosures, front panels, crap like that
2020-05-05T12:33:47 < Cracki> ic
2020-05-05T12:34:09 < Cracki> that may benefit from sheet metal functionality
2020-05-05T12:34:42 < jadew> it might, but not now, the enclosures I'm making are CNCed

2020-05-05T12:39:58 < jadew> the professional one
2020-05-05T12:41:23 < Cracki> do they make you pay for fusion360?
2020-05-05T12:41:38 < jadew> they do now
2020-05-05T12:41:41 < Cracki> heh
2020-05-05T12:42:14 < jadew> you can only not pay if you're a hobbyist, and are making videos I think
2020-05-05T12:42:44 < jadew> or a startup with less than 10k/year business
2020-05-05T12:43:05 < jadew> and even if you qualify there, you have to agree to tell be on camera with them
2020-05-05T12:43:20 < jadew> and they give those licenses on a case-by-case basis
2020-05-05T12:43:29 < Cracki> do a startup for enclosure design. that might fly below 10k/y
2020-05-05T12:43:40 < jadew> heh
2020-05-05T12:43:52 < Cracki> meh I hate applications of any kind
2020-05-05T12:43:57 < strata> or just do a startup in the USA (not SFBA)
2020-05-05T12:44:02 < Cracki> it's practically begging, even if it's a job application
2020-05-05T12:44:16 < jadew> yeah

2020-05-05T12:45:56 < jadew> zyp, a couple of months ago

2020-05-05T12:47:14 < jadew> yeah
2020-05-05T12:47:18 < jadew> and for startup?
2020-05-05T12:47:48 < Cracki> this doesn't mention startups, perhaps elsewhere https://www.autodesk.com/campaigns/fusion-360-for-hobbyists
2020-05-05T12:48:26 < zyp> https://www.autodesk.com/campaigns/fusion-360/startups
2020-05-05T12:48:45 < jadew> ah, it's 100k
2020-05-05T12:48:54 < jadew> I could swear it was 10k when I first checked the changes
2020-05-05T12:49:09 < Cracki> but " less than 3 years old"
2020-05-05T12:49:18 < jadew> yeah, that too
2020-05-05T12:49:28 < jadew> Businesses must design or manufacture their own physical products and be willing to share their story with the Fusion 360 community.
2020-05-05T12:49:38 < zyp> you're not really a startup if your business is older than three years
2020-05-05T12:50:02 < Cracki> yt video should cover that clause, except if they want some kind of blog post on their site too
2020-05-05T12:50:09 < jadew> well, I kept my company alive but didn't do anything with it for several years
2020-05-05T12:51:02 < Cracki> I don't like that they want all those files in their cloud. you can export shit but meh
2020-05-05T12:51:02 < jadew> anyway, the point is that I don't qualify for neither a startup license nor a hobby license
2020-05-05T12:51:16 < jadew> yeah, I don't like that either
2020-05-05T12:51:20 < Cracki> pay the iron price for inventor maybe
2020-05-05T12:51:33 < Cracki> or freecad :>
2020-05-05T12:52:14 < jadew> the biggest issue with autocad tools is that it's a yearly license
2020-05-05T12:52:38 < jadew> I want something I can only pay once
2020-05-05T12:52:45 < Cracki> did freecad do chamfers and fillets as easily as autodesk?
2020-05-05T12:53:07 < Cracki> apart from inventor being costly (or free for students), it is a perpetual license afaik
2020-05-05T12:53:08 < jadew> I don't know, I didn't manage to extrude anything yet
2020-05-05T12:53:34 < jadew> Cracki, on their site it says 2k/year
2020-05-05T12:53:45 < jadew> 5.6k / 3 years
2020-05-05T12:53:50 < Cracki> according to this, fillets look like what you do in autodesk, except clunkier https://wiki.freecadweb.org/PartDesign_Fillet
2020-05-05T12:53:53 < jadew> not even a big discount... jeez
2020-05-05T12:53:56 < Cracki> oh ok then
2020-05-05T12:55:50 < Cracki> buttons for add/remove... in autodesk you just click those things and maybe a ctrl/alt/shift to deselect
2020-05-05T12:58:23 < Cracki> wait, they have two articles on this? there's a diff between "part" and "partdesign"? open sores man https://wiki.freecadweb.org/Part_Fillet
2020-05-05T12:59:32 < Cracki> heh, naming things is hard https://forum.freecadweb.org/viewtopic.php?t=27436
2020-05-05T13:06:12 < jadew> ok, I don't think freecad is that bad
2020-05-05T13:07:23 < jadew> https://imgur.com/a/zhVA9P5
2020-05-05T13:07:25 < jadew> made that
2020-05-05T13:09:38 < Cracki> https://knowyourmeme.com/memes/i-made-this
2020-05-05T13:09:56 < Cracki> so it can do holes and chamfers on circles
2020-05-05T13:10:13 < Cracki> does it happen to have a "tapped hole" option?
2020-05-05T13:10:55 < jadew> you mean tapered?
2020-05-05T13:11:06 < Cracki> ooh https://wiki.freecadweb.org/PartDesign_Hole
2020-05-05T13:11:10 < Cracki> no tapped, threaded
2020-05-05T13:11:24 < jadew> ah, yeah, it has thread support too
2020-05-05T13:11:26 < jadew> I like it
2020-05-05T13:11:39 < jadew> it's a step back from Fusion, but it's free
2020-05-05T13:11:50 < jadew> the price is right
2020-05-05T13:12:13 < Cracki> har
2020-05-05T13:12:59 < jadew> this whole pricing thing is very interesting
2020-05-05T13:13:52 < jadew> the conclusion here is that autodesk makes more money if they don't take my 500 that I'm willing to pay for fusion
2020-05-05T13:16:20 < strata> where have i seen that before... companies that make more money by not charging lots of money...
2020-05-05T13:16:24 < strata> oh right... EVERYWHERE!
2020-05-05T13:17:13 < jadew> strata, it's probably about how they want to do business too
2020-05-05T13:17:57 < jadew> if someone charges 1000 for a pen and he only sells two, then you'll get great customer support, because he has spare time to talk to you and understand your concerns about the pen
2020-05-05T13:18:29 < jadew> if you pay him 2c over the manufacturing cost, then he'll have to make millions
2020-05-05T13:18:45 < jadew> so he won't be able to talk to you
2020-05-05T13:18:58 < jadew> I guess that's a choice the company makes for themselves
2020-05-05T13:19:45 < jadew> also, if you're going to make a pen for 1000, you'll probably put at least $20 worth of BOM into it
2020-05-05T13:19:58 < jadew> and a lot of R&D and contemplating the beauty of things
2020-05-05T13:21:09 < jadew> jeez, there are some things in Fusion...
2020-05-05T13:21:25 < jadew> for example, for Visibility: you don't have checkbox that you can just click
2020-05-05T13:21:31 < jadew> you have a dropdown
2020-05-05T13:21:44 < jadew> you fist click the dropdown, and then you click true/false
2020-05-05T13:22:22 < jadew> someone couldn't be arsed to implement checkboxes in those lists controls
2020-05-05T13:25:03 < jadew> can't believe how much stupid shit is there
2020-05-05T13:25:16 < jadew> like... at every step
2020-05-05T13:25:41 < jadew> for example, to set the radius of a circle, you can't use the same shortcut for dimension, because it's a circle, so you need the one for radius
2020-05-05T13:25:59 < jadew> like wtf... you already know it's a fucking circle and I asked to set a dimension, give me the damn radius crap
2020-05-05T13:26:15 < Steffanx> Warez some proper tool and be done with it
2020-05-05T13:26:32 < jadew> too much hassle
2020-05-05T13:26:53 < Thorn> how's the lunix situation on Sitara compared to mp1? which one is easier to develop for / better supported?

2020-05-05T13:49:12 < karlp> heh, looking for a serbian dns registrar off this list: https://www.rnids.rs/en/registrars/list-accredited-registrars
2020-05-05T13:49:31 < karlp> the first one I've found so far with english just has "under construction" for the entire site
2020-05-05T13:52:57 < qyx> Thorn: I'll tell you, I have some work to be done with buldroot on some octavo thing (sitara based)
2020-05-05T13:53:42 < Thorn> does buildroot come with their sdk?
2020-05-05T13:55:08 < mawk> sdk ?
2020-05-05T13:55:17 < Thorn> btw mp1 actually looks better peripheral wise than most am335x except the senior ones, and there's no dual core 335x
2020-05-05T13:55:37 < Thorn> mawk see link above
2020-05-05T13:55:44 < mawk> am335x "mcu" is not really a mcu right
2020-05-05T13:55:50 < mawk> or it is, but it's not arm
2020-05-05T13:55:56 < mawk> it's like a custom core thing

2020-05-05T14:06:00 < Thorn> fucke dot rs
2020-05-05T14:06:06 < Ad0> I want to use std::array but my flash size is a bit small (64k). but I get flash overflow
2020-05-05T14:07:02 < Ad0> I guess this might because it drags in all the STL debug stuff?
2020-05-05T14:07:20 < Thorn> Ad0 etl::array
2020-05-05T14:07:33 < Thorn> https://www.etlcpp.com/
2020-05-05T14:07:38 < Ad0> cool! 
2020-05-05T14:07:57 < qyx> Thorn: idk yet
2020-05-05T14:08:00 < Thorn> etl::vector is also very usable, etc.
2020-05-05T14:08:00 < qyx> probably no
2020-05-05T14:08:35 < Ad0> thanks a lot.
2020-05-05T14:08:47 < Ad0> it's more pretty than uint8_t *data, size_t length
2020-05-05T14:08:50 < qyx> I suppose drivers are ijn the kernel, I will have to modify devicetree and thats all
2020-05-05T14:09:00 < mawk> std::array is just a regular array
2020-05-05T14:09:10 < Ad0> yeah and that's good
2020-05-05T14:09:15 < mawk> it shouln't have overhead
2020-05-05T14:09:28 < Ad0> for example a mac address always is 6 bytes so I can just typedef it with the array
2020-05-05T14:10:43 < mawk> what is it overflowing with ?
2020-05-05T14:17:17 < Ad0> region `FLASH' overflowed by 113776 bytes
2020-05-05T14:17:33 < Ad0> kinda brutal when the flash itself is 64k lol.
2020-05-05T14:18:08 < Ad0> I use stm32cubexIDE, what's the appropiate location for etl ? Core/Inc/etl ? 
2020-05-05T14:28:00 < Ad0> warning: inline variables are only available with -std=c++1z or -std=gnu++1z
2020-05-05T14:29:55 < Ad0> I guess C++17 is not enabled by default
2020-05-05T14:31:14 < zyp> well, considering your compiler calls it C++1z, it's probably fairly old
2020-05-05T14:31:31 < Ad0> yeah
2020-05-05T14:40:45 < Ad0> it's the GCC that comes with the stm32cubeide
2020-05-05T14:43:06 < Ad0> maybe I should switch to vs code and just use stmcubeide as a code generator for the package
2020-05-05T14:51:54 < dongs> that etl thing looks great, if only it wasn't C++
2020-05-05T14:53:37 < Thorn> dongs it would not exist then

2020-05-05T15:04:19 < Steffanx> ...
2020-05-05T15:12:17 < dongs> at least altium is better than kikecad
2020-05-05T15:12:20 < Thorn> zyp yes that one
2020-05-05T15:12:43 < zyp> looks interesting
2020-05-05T15:12:58 < jpa-> has altium fallen that low that the best dongs can figure is "at least better than kicad"
2020-05-05T15:13:10 < jpa-> soon it will be "well, it still beats fritzing"
2020-05-05T15:13:15 < Steffanx> :D

2020-05-05T17:51:09 < Laurenceb> oh wait
2020-05-05T17:52:11 < jadew> local CNC place I was using quoted me 50% more for a part they already made for me in the past
2020-05-05T17:52:13 < englishman> my lorawan should be active as of today
2020-05-05T17:52:17 < englishman> if digikey delivers
2020-05-05T17:52:35 < jadew> and the price in high qty, they quoted me what they made it for in qty last year...
2020-05-05T17:52:35 < englishman> lorawan sure is awesome
2020-05-05T17:52:44 < jadew> I guess I'll have to find another place
2020-05-05T17:53:31 < Steffanx> They have more then enough work i guess or their last quote was just too low and they figured that out?
2020-05-05T17:54:10 < jadew> Steffanx, don't know... the name of the company changed also, but they're the same people
2020-05-05T17:54:23 < jadew> anyway, 50% more is a deal breaker
2020-05-05T17:55:38 < jadew> I should just get a CNC...
2020-05-05T17:56:06 < jadew> at least for prototypes

2020-05-05T19:04:43 < zyp> nice, found a «bug» in sigrok's usb decoder
2020-05-05T19:05:11 < zyp> I mean, I'm feeding it invalid data, but it's still interpreting it wrong
2020-05-05T19:06:46 < Laurenceb> cyber-threat!!

2020-05-05T19:07:30 < zyp> https://bin.jvnv.net/file/ZKlmW.png <- I'm sending an empty data packet without the crc field, because I haven't made the crc generator yet, sigrok ignores the end of packet and thinks the next packet is part of the data payload

2020-05-05T19:45:47 < zyp> since packets are already delimited by an end of packet symbol, you have packet boundaries
2020-05-05T19:45:58 < zyp> adding a size field wouldn't add any new information, just overhead

2020-05-05T19:57:44 < Cracki> or maybe switch to some other project that decodes protocols. I've heard of https://github.com/GlasgowEmbedded/glasgow
2020-05-05T19:58:02 < zyp> well, my main plan is to add the CRC so that the packet is actually correct
2020-05-05T19:58:35 < zyp> it's not like the decoder not working properly is blocking my progress in any way, it's more of a curiosity
2020-05-05T19:58:42 < Cracki> good point
2020-05-05T20:03:16 < jpa-> many sigrok decoders have things to improve with regards to handling invalid data

2020-05-05T20:27:34 < Cracki> I wonder if they have a masterplan yet to make stacking more modular. there aren't any standalone NRZ or manchester decoders yet (says their wiki), but those are inside several other PDs
2020-05-05T20:28:26 < Cracki> guess that'll need some individual to make sense of it all and lay a strong hand on the code

2020-05-05T20:50:20 < jpa-> no, that's manchester or one of the related codes
2020-05-05T20:50:28 < Cracki> or maybe that was nrzi, or rz, or whatever types there are
2020-05-05T20:50:59 < Cracki> manchester could be useful for SWO encoded like that (instead of plain uart)

2020-05-05T21:08:17 < zyp> but I'm guessing what's happening is that it's raising an exception here: https://github.com/sigrokproject/libsigrokdecode/blob/master/decoders/usb_packet/pd.py#L346 (or perhaps somewhere nearby), which gets handled and ignored above decode(), and then decode() is called again, skipping lines 394/395 that resets the current packet, so the bits for the next packet gets appended onto the one from the previous 
2020-05-05T21:08:23 < zyp> before decoding
2020-05-05T21:08:25 < Cracki> when i needed envelope/demod I just exported the recording to raw bytes and munched on it with numpy
2020-05-05T21:08:56 < zyp> but I'm not sure I want to figure out how to modify and build this so I can test a fix
2020-05-05T21:09:20 < Cracki> PDs are tricky to debug aye. if you do it in PV, you have to get the PV debug build that actually uses terminal output, then you need another switch to raise log level, then you can do printlining in the PD source
2020-05-05T21:10:08 < Cracki> for PDs you don't need to build anything, you just need to figure out where it looks for these scripts and make sure you're editing the right file (it's not "shadowed" by some other location)

2020-05-05T21:12:05 < Cracki> I think I had that when I worked on some PDs... but PV liked to crash from what I did, and opening settings all the time was too much for me. I just worked from terminal output
2020-05-05T21:12:20 < Cracki> I didn't even consider using pdb. I just printlined it all until it worked.

2020-05-06T00:11:32 < englishman> there will be power there for heaters eventually
2020-05-06T00:11:35 < qyx> innovating much
2020-05-06T00:11:50 < ds2> trying to thinking of a cheap way to monitor water levels in a self watering planter
2020-05-06T00:11:55 < englishman> battery life should be super long tho.
2020-05-06T00:12:08 < qyx> ds2: capsense
2020-05-06T00:12:16 < englishman> like, selfdischarge >> lorawan
2020-05-06T00:12:17 < kakimir> I drove pass a reindeer store Steffanx
2020-05-06T00:12:23 < kakimir> not in the video though
2020-05-06T00:12:36 < kakimir> too tired to stop there for the goods
2020-05-06T00:12:41 < ds2> qyx: that fails the cheap test once radios and such are added... got to do this at 10-20 places
2020-05-06T00:12:56 < kakimir> maybe I order some cans from internets and send them
2020-05-06T00:13:08 < qyx> ds2: is a 0.80e radio expensive?
2020-05-06T00:13:25 < kakimir> you can get a radio for 0.8?
2020-05-06T00:13:26 < qyx> also I said I will try to do it with IR LEDs

2020-05-06T00:14:48 < qyx> there are cheaper ones, analog only
2020-05-06T00:14:52 < qyx> this one has i2c
2020-05-06T00:17:31 < Steffanx> Oh lol you had to give permission for real?
2020-05-06T00:17:33 < ds2> qyx: what kind of radio is 0.80e?
2020-05-06T00:17:52 < qyx> ds2: see the link
2020-05-06T00:18:00 < qyx> Si4012 for example
2020-05-06T00:18:24 < qyx> it is a sub-1GHz FSK transmitter only
2020-05-06T00:19:11 < Steffanx> Mr kakimir. Not sure what I'm looking at, but..

2020-05-06T02:56:08 < mawk> I'm ashamed to live here
2020-05-06T02:56:20 < Laurenceb> just stick glorified mine carts in a sewer pipe
2020-05-06T02:56:40 < mawk> even if you break apart the hyperloop, take every piece at a time
2020-05-06T02:56:42 < mawk> it's still ridiculous
2020-05-06T02:56:51 < mawk> and ridiculousness is a transitive property

2020-05-06T02:59:06 < mawk> the paris subway is hvdc through the rails
2020-05-06T02:59:09 < mawk> see, they stole your idea
2020-05-06T03:00:04 < mawk> show me the pic Steffanx 
2020-05-06T03:00:51 < Laurenceb> lol neat
2020-05-06T03:02:01 < Laurenceb> surely you mean shielded third rail?
2020-05-06T03:02:26 < mawk> it's not shielded
2020-05-06T03:02:28 < mawk> but it's a third rail yes
2020-05-06T03:02:39 < Laurenceb> ah thats different - needs an annoying shoe
2020-05-06T03:02:47 < mawk> yeah
2020-05-06T03:02:51 < Laurenceb> in uk they have that, the trains are really shit
2020-05-06T03:02:56 < mawk> well people keep pissing and falling on the tracks
2020-05-06T03:03:02 < mawk> you can't use the regular rails
2020-05-06T03:03:02 < Laurenceb> like 65mph and the air con kills the speed
2020-05-06T03:03:12 < mawk> you need a third rail between the two pairs of tracks
2020-05-06T03:03:35 < mawk> some stations have special doors to prevent falling, but even if all stations had that people still find creative ways to fall on the tracks
2020-05-06T03:03:47 < Laurenceb> I was thinking like +2kv down one rail and -2kv on the other
2020-05-06T03:03:57 < Laurenceb> then GRP axels
2020-05-06T03:05:18 < mawk> the shoe slows it that down ?
2020-05-06T03:05:29 < mawk> it's just sliding on it
2020-05-06T03:05:52 < Laurenceb> nah it starts arcing at about 80mph due to air getting into the gap
2020-05-06T03:06:07 < Laurenceb> they have to reduce the current at higher speed so its a tricky balance
2020-05-06T03:06:22 < Laurenceb> just turning on the air con at 70mph slows the train
2020-05-06T03:07:25 < mawk> then remove the air
2020-05-06T03:07:37 < Laurenceb> nah that just makes it worse aiui
2020-05-06T03:07:51 < Laurenceb> all sorts of nasty plasma stuff starts happening
2020-05-06T03:07:55 < mawk> a
2020-05-06T03:07:58 < mawk> I meant with oil
2020-05-06T03:08:02 < Laurenceb> then conductive dust gets thrown all round the tunnel
2020-05-06T03:08:06 < mawk> I guess that happens as well
2020-05-06T03:08:49 < Laurenceb> aiui chinese high speed rail has to operate at reduced speed due to similar issues with the pantograph
2020-05-06T03:09:00 < mawk> that sucks
2020-05-06T03:09:01 < Laurenceb> but its much faster than third rail of course
2020-05-06T03:09:02 < mawk> but
2020-05-06T03:09:06 < mawk> why wouldn't it happen with rails as well

2020-05-06T03:09:35 < mawk> the london underground was exceptionnally dirty, I found

2020-05-06T03:10:14 < Laurenceb> mawk: lots of load from the weight of the train on the wheels
2020-05-06T03:10:30 < Laurenceb> london underground main issue is the air circulation
2020-05-06T03:10:34 < Laurenceb> or rather lack of
2020-05-06T03:10:45 < zyp> yeah, shit's hot as fuck too
2020-05-06T03:10:48 < mawk> well why can't you load the shoe like that then ?
2020-05-06T03:10:51 < Laurenceb> >relies on the trains as air circulators
2020-05-06T03:10:59 < mawk> I guess it would ruin it too fast
2020-05-06T03:11:09 < Laurenceb> mawk: shoes slide so they wear really fast under load
2020-05-06T03:11:11 < Laurenceb> yeah
2020-05-06T03:11:15 < zyp> and the trains in the deep rail lines are kinda cramped

2020-05-06T06:25:20 < dongs> haha
2020-05-06T06:25:26 < dongs> imagine, joining some internet of shit startup
2020-05-06T06:25:30 < dongs> who are too cheap to use proper tools
2020-05-06T06:25:34 < dongs> and all their shit is in kikecad
2020-05-06T06:25:36 < dongs> and it doesnt wrok
2020-05-06T06:25:41 < dongs> and you spend like a week redrawing all tehri shit
2020-05-06T06:25:43 < Spirit532> all of my designs work

2020-05-06T06:26:18 < dongs> incorrect
2020-05-06T06:27:49 < dongs> haha, apparently if you import a kikecad board once it breaks all your colorscheme
2020-05-06T06:28:06 < dongs> > - import of a PCB will change your PCB colors to the KiCAD scheme of rust red for top and green for bottom. This will affect all subsequent PCB's even previous PCB designs. So make sure to back up your color scheme...

2020-05-06T06:42:02 < dongs> In Tools -> Preferences -> PCB -> Defaults -> Via the option "Tented" is checked, but it is only for vias which are placed manualy.

2020-05-06T08:15:31 < jadew> turns out they have another edge on all cylinders or circular objects, and they wouldn't fix it, because "it's how the underlying engine works and it's not a bug", even tho it creates additional faces and no other CAD program works like that
2020-05-06T08:15:48 < jadew> and it seems it has been reported as an issue for years
2020-05-06T08:16:00 < jadew> open source rocks!
2020-05-06T08:32:59 < Cracki> odd.
2020-05-06T08:33:12 < Cracki> on the right edge it's doing ok
2020-05-06T08:33:17 < Cracki> those weirdos
2020-05-06T08:33:26 < Cracki> none of them probably know how to fix the engine
2020-05-06T08:33:35 < jpa-> yeah, it's just that the cylinders have the funny seam and in jadew's drawing it happens to be right at the fillet edge
2020-05-06T08:33:58 < Cracki> some long bearded wizard wrote it in a drug fueled haze about a thousand moons ago
2020-05-06T08:34:58 < Cracki> cylinder with a visible seam, that's just silly
2020-05-06T08:35:36 < jpa-> "visible"
2020-05-06T08:36:26 < jpa-> but yeah, i can imagine that updating the engine to fully support faces with holes would be significant effort
2020-05-06T08:36:49 < jpa-> can't expect them to have much resources without money

2020-05-06T09:04:31 < jadew> it's possible other cad programs work the same, but they deal with it in the background

2020-05-06T09:36:21 < jpa-> IIRC at least the common file formats like STEP do support faces with holes, so probably more advanced packages don't need the extra edge
2020-05-06T09:36:36 < jpa-> would be interesting to see what freecad does if you make a cylinder in fusion360, export STEP and import to freecad
2020-05-06T09:37:34 < jadew> jpa-, I can try that, give me a sec
2020-05-06T09:41:25 < jadew> has a seam
2020-05-06T09:43:54 < jpa-> can you upload the step, i want to see if it is already in the file or if freecad adds it in import
2020-05-06T09:44:20 < Cracki> it's ok to model it as a wrapped rectangle but then you have to make sure that seam isn't "special" in any way, i.e. normal, curvature, ... matches, and all operations can handle it like it isn't even there
2020-05-06T09:45:20 < Cracki> makes me wonder if they model it as two circles and a bent rectangle, or as an extruded circle. extrusion should leave no seam.
2020-05-06T09:45:55 < Cracki> if you model a circle as having a beginning and an end... but eh
2020-05-06T09:48:12 < jpa-> for cylinders doing it seamless is probably not that big of a deal if one already handles faces with holes, which are quite useful for other things also - but i wonder how more advanced cad packages handle spheres
2020-05-06T09:49:00 < Cracki> surface of revolution I'd guess
2020-05-06T09:49:19 < Cracki> possible singularity at the poles
2020-05-06T09:49:35 < Cracki> or maybe some implicit formulaic expression
2020-05-06T09:50:29 < Cracki> I don't think it's all that common to model solids as a bunch of surfaces either
2020-05-06T09:50:38 < jpa-> how else?
2020-05-06T09:50:39 < Cracki> it can be CSG too
2020-05-06T09:51:38 < Cracki> with primitive volumes and swept/lofted/... profiles
2020-05-06T09:53:28 < Cracki> I can't imagine how they handle binary operations like union or subtraction. that leaves edges and faces I can select, so it probably has implied edge and face objects that are recalculated if the parent changes, and you can work off those secondary objects... who knows

2020-05-06T09:54:12 < jadew> jpa-, sure, give me a sec, I was answering on the freecad forums
2020-05-06T09:54:28 < jadew> https://forum.freecadweb.org/viewtopic.php?f=3&t=46081
2020-05-06T09:54:56 < jpa-> it's actually quite weird how freecad seems to handle circular faces with holes just fine, it is just the vertical face that gets the seam  https://jpa.kapsi.fi/stuff/pix/cylinder.png
2020-05-06T09:55:23 < jpa-> somehow it seems to me that those are topologically quite similar, unless there is some underlying limitation that only flat faces can have holes
2020-05-06T09:55:26 < jadew> yeah

2020-05-06T09:56:45 < jpa-> *chrisb
2020-05-06T09:56:56 < jadew> yeah...
2020-05-06T09:57:06 < jadew> http://5.12.190.252/stuff/cylinder.step
2020-05-06T10:05:53 < jpa-> hmm, it's actually quite funny - it has the surface as seamless #38=CYLINDRICAL_SURFACE('',#56,34.1613566255639);  but it also has the seam in FACE_OUTER_BOUND definition
2020-05-06T10:06:58 < jadew> I think in the post they plucked my reply out of, the other guys were saying that if you import the output from FreeCAD into a pro tool, the seam is gone
2020-05-06T10:07:30 < jpa-> i think Cracki is correct and the advanced tools just hide the seam & special case it
2020-05-06T10:07:37 < jadew> which would suggest that it's just an implementation detail, and that FreeCAD is handling it wrong.
2020-05-06T10:07:40 < jadew> yeah
2020-05-06T10:07:56 < jpa-> i guess it is quite easy to detect as it is just the same seam at both ends of the surface
2020-05-06T10:08:57 < jadew> they could probably flag it, and ignore it in all operations that are looking for seams and other faces
2020-05-06T10:08:57 < Cracki> "special case" it may be the case that treating it as it is causes no such artefacts... if they do it well
2020-05-06T10:09:11 < jadew> Cracki, right
2020-05-06T10:09:14 < jadew> I considered that as well
2020-05-06T10:09:15 < Cracki> if there's a cylindrical surface, why is there a seam too?
2020-05-06T10:09:21 < Cracki> is that additional info or vital info?
2020-05-06T10:10:27 < jadew> so their suggestion is to rotate my sketch
2020-05-06T10:10:40 < jadew> great, now I have to keep track of offsets

2020-05-06T10:28:51 < jpa-> fusion360 also puts the seam at 4.1835596046028E-15 instead of 0, so maybe that's one way of handling it as freecad is also fine as long as it doesn't exactly hit one of the other edges
2020-05-06T10:29:44 < jadew> ah ha
2020-05-06T10:30:12 < jadew> I actually thought of that solution, but didn't know if it would work well in practice because of snapping
2020-05-06T10:30:17 < jadew> I guess it does
2020-05-06T10:30:51 < Cracki> heh I think that's just them not bothering to round floats to a humanly pretty string
2020-05-06T10:31:25 < Cracki> if 4e-15 makes something "not zero", the programmers need to be shot
2020-05-06T10:31:50 < Cracki> comparing floats, especially in this kinda stuff, needs a tolerance, and 4e-15 should be considered zero enough
2020-05-06T10:32:45 < jadew> yeah, that was my thought process too, and why I didn't consider it a real solution, but maybe it actually works
2020-05-06T10:33:03 < jadew> if two points are coincidental, then any error is too much
2020-05-06T10:34:30 < jpa-> yeah, 4e-15 is at the limit of double accuracy so it could just as well be caused by inaccuracies
2020-05-06T10:35:16 < Cracki> relative to 1.0 but yes
2020-05-06T10:35:54 < Cracki> they might have calculated that as the sin/cos of some angle
2020-05-06T10:36:41 < jpa-> interestingly if i modify the .step so that the edge is not there and the cylinder is modeled as a face between two circles, freecad happily imports it and adds the edge between the points that define the end face circles
2020-05-06T10:37:57 < jpa-> it seems like STEP format defines circles using a point on the perimeter and two axes
2020-05-06T10:42:10 < jpa-> i can even slant the edge by moving the circle points, but i slant it by more than ~10e-15, freecad forces the edge to be parallel to the cylinder axis
2020-05-06T10:42:36 < jpa-> looks like freecad's importing is surprisingly robust

2020-05-06T11:21:03 < jpa-> in a way, the existence of freecad and similar free solutions probably contributes to the gap - it's a very significant amount of effort to make something better than freecad, and then it is hard to sell it at hobbyist prices
2020-05-06T11:21:18 < Cracki> I feel the same with PCB design programs. either it's noncommercial, or you pay through the nose for something usable
2020-05-06T11:21:29 < jadew> jpa-, yeah, that's quite common
2020-05-06T11:21:36 < jadew> OSS does that
2020-05-06T11:21:54 < Cracki> open source is like made in china
2020-05-06T11:22:02 < jpa-> fusion360 etc. pay for themselves by luring people into particular vendor's products, but that causes stuff like mandatory subscription, restrictive license terms and intentionally making things worse

2020-05-06T11:24:28 < jadew> I'm tempted to start writing one, but I don't think I have the time to dedicate to such a project
2020-05-06T11:25:07 < jadew> would probably take 1 year of intensive work to get it to usable state
2020-05-06T11:25:33 < jadew> and then it would need polishing for even longer
2020-05-06T11:26:16 < jadew> but then you can forget about the stupid market gap and sell at $1500/seat :P
2020-05-06T11:30:03 < jadew> jpa-, can you make threads in FreeCAD?
2020-05-06T11:30:11 < jadew> not necessarily model them, just mark them as threads
2020-05-06T11:30:19 < jadew> so they show up in the technical drawing
2020-05-06T11:31:23 < jadew> fusion has this option where it does exactly that, it doesn't model them, but sets the correct diameter of the surface (so you can actually thread them afterwards), based on the screw type you select
2020-05-06T11:31:36 < jadew> and then you can show the feature in the drawing
2020-05-06T11:31:39 < jadew> works great

2020-05-06T12:00:48 < azonenberg> Hi guys... I'm looking to build an embedded USB host with a stm32 using a type-C connector
2020-05-06T12:01:02 < azonenberg> It only needs to support talking to one specific peripheral
2020-05-06T12:01:17 < azonenberg> Can I use one of the stm32f4's with a usb otg controller and just disable the OTG logic, forcing it into host mode?
2020-05-06T12:01:36 < azonenberg> i don't see any stm32s with an actual host controller, i only see device and otg
2020-05-06T12:03:36 < PaulFertser> azonenberg: otg means it can act as both, of course you can use it as a host only.
2020-05-06T12:04:02 < azonenberg> PaulFertser: my question was specifically about using it on a type-c cable without the OTG pin etc
2020-05-06T12:05:09 < azonenberg> backing up a bit, my actual goal is to use a readily available connector to communicate with and power a custom peripheral that needs +/- 7VDC which is not a standard PD voltage. I want to avoid needing a DC-DC module on the device
2020-05-06T12:05:59 < azonenberg> So my tentative plan is to implement a nonstandard usb "alternate mode" by running usb 2.0 and normal Vbus, negotiate via some vendor specific endpoints to confirm i'm talking to one of my peripherals
2020-05-06T12:06:10 < azonenberg> then apply +7V to two of the SS data pairs and -7V to the other two 
2020-05-06T12:06:20 < azonenberg> the +5 Vbus will only be used to power the MCU on the peripheral
2020-05-06T12:06:46 < azonenberg> In this mode the USB 2.0 data channel would remain operational and be used for control
2020-05-06T12:08:19 < azonenberg> Unless you can think of a better idea? The actual device will have two connections, a SMA coaxial cable for RF signal from device to host and the USB-C cable for power and control

2020-05-06T12:10:41 < PaulFertser> azonenberg: since you're layout the board yourself you can tie idpin of the MCU to whatever needed.
2020-05-06T12:10:43 < azonenberg> usb-c seemed a logical choice
2020-05-06T12:10:53 < azonenberg> Although i am open to other suggestions as well
2020-05-06T12:11:24 < Steffanx> zyp is our genie in a usbottle
2020-05-06T12:13:05 < azonenberg> and hmm, yeah i guess i could just tie off ID at the host
2020-05-06T12:13:27 < azonenberg> then i'll have to figure out cable orientation i think but that should be easy to do with a pullup resistor on the CC pin and a GPIO
2020-05-06T12:13:38 < PaulFertser> The plan sounds cool. It's a bit strange you want to use an MCU as usb host as fancy scopes are using fully-featured boards and boot full OS.
2020-05-06T12:13:48 < azonenberg> PaulFertser: I'm doing something different
2020-05-06T12:13:53 < azonenberg> This is a headless scope that won't run an OS
2020-05-06T12:14:03 < azonenberg> it's basically an ADC bolted onto a TCP offload engine with a stick of DDR3 in between as a FIFO
2020-05-06T12:14:31 < azonenberg> you connect via an ordinary PC over two sockets, one has a SCPI command interface for setting gain/offset, sample rate, etc
2020-05-06T12:14:36 < azonenberg> and the other is waveform data via a pub/sub interface
2020-05-06T12:14:51 < azonenberg> you say "I want to see channel 2" and then any time the scope triggers channel 2 pushes you a waveform, no polling of status registers or anything
2020-05-06T12:14:51 < Thorn> azonenberg can't you negotiate a non-standard voltage over standard PD if you have control over both ends of the interface?
2020-05-06T12:15:07 < azonenberg> Thorn: PD protocol looked vastly more complex. also it doesn't support bipolar rails
2020-05-06T12:15:11 < azonenberg> PD is always ground and one voltage
2020-05-06T12:15:25 < azonenberg> I need a negative rail for the analog logic on the probe
2020-05-06T12:15:35 < azonenberg> and would like to keep noisy SMPSes away from the sensitive frontend on the probe
2020-05-06T12:15:44 < azonenberg> so my plan was to have a DC-DC on the scope then just LDOs on the probe
2020-05-06T12:16:35 < azonenberg> if i wanted to be fully standard i'd want to implement a vendor specific usb alternate mode that defined power instead of e.g. displayport on the SS data pairs
2020-05-06T12:16:47 < azonenberg> But it looks like doing AFs is a nightmare too
2020-05-06T12:17:00 < PaulFertser> Hm, so a usb c cable is a smart shit. Will it just pass your data through?
2020-05-06T12:17:25 < Thorn> a cable may easily have transceiver chips on SS pairs
2020-05-06T12:17:26 < jpa-> C-to-C cable is nothing but wires AFAIK
2020-05-06T12:17:27 < PaulFertser> And voltages
2020-05-06T12:17:39 < azonenberg> Thorn: i thought only expensive active cables did that
2020-05-06T12:17:40 < jpa-> unless it is extra long or something
2020-05-06T12:17:51 < azonenberg> or C-to-other-stuff adapters
2020-05-06T12:19:16 < jpa-> SBU1 and SBU2 could be one possibility for power transfer also
2020-05-06T12:19:45 < Thorn> azonenberg so you may actually need to talk to the *cable* first (over PD) to determine if it can pass power through the way you want it to (assuming you can even do that within the capabilities of PD, I'm not sure)
2020-05-06T12:20:00 < azonenberg> Thorn: my thought was to simply say, no active cables allowed
2020-05-06T12:20:44 < Thorn> well if the penalty is a fried cable you should make an effort to check if it's safe
2020-05-06T12:20:55 < azonenberg> yes but i'm not sure how to do that without a PD controller on the host
2020-05-06T12:21:00 < azonenberg> which again will make things vastly more complex
2020-05-06T12:22:29 < jpa-> azonenberg: how much current do you need on the +-7V?
2020-05-06T12:23:31 < azonenberg> jpa-: few tens of mA. the LMH5401 is a potential buffer for an active probe and needs 55 mA
2020-05-06T12:23:39 < azonenberg> no more than 100 for sure

2020-05-06T12:25:26 < ds2> why not fit it into PD?
2020-05-06T12:25:39 < azonenberg> ds2: how can i get two separate voltages out of PD?
2020-05-06T12:25:49 < azonenberg> i need +7 and -7, otherwise i will need to put a dc-dc on the probe
2020-05-06T12:25:54 < ds2> why do you need 2 seperate voltages?
2020-05-06T12:26:15 < azonenberg> because the device is an oscilloscope probe that can handle inputs below ground

2020-05-06T12:26:49 < azonenberg> so I need +/- 5V or so to power the amplifier and i need some headroom for the LDOs to get ultra low noise output
2020-05-06T12:27:31 < ds2> is it AC or DC coupled?

2020-05-06T12:27:45 < azonenberg> the waveform output is DC coupled and goes over a separate SMA coaxial cable
2020-05-06T12:28:08 < azonenberg> the USB channel is for adjusting gain/offset and supplying power
2020-05-06T12:28:33 < ds2> one voltage vs 2 is a matter of prospective. where is the GND's
2020-05-06T12:28:47 < azonenberg> Ground is in the middle
2020-05-06T12:28:52 < jpa-> one way might be to have negotiation between your custom devices that goes like: 1. host queries device "do you want voltage?"  2. host enables power with tiny current limit to avoid damaging anything, device makes sure it is not drawing power   3. device verifies it sees +-7V ok   4. host enables higher current
2020-05-06T12:28:54 < azonenberg> I need 7V above and 7V below the usb rail
2020-05-06T12:29:10 < azonenberg> the usb ground*
2020-05-06T12:29:16 < azonenberg> because that is also going to be the analog ground 
2020-05-06T12:29:18 < azonenberg> on the coax shield
2020-05-06T12:30:55 < azonenberg> jpa-: honestly i think it will be fine because usb SS is ac coupled
2020-05-06T12:31:06 < azonenberg> and so i would expect active cables to have coupling caps. Which should easily handle 7V across them
2020-05-06T12:31:26 < azonenberg> so an active cable will act as an open circuit to a DC supply, and not work, but shouldn't die either
2020-05-06T12:31:31 < jpa-> yeah, i also expect it would be fine in almost all cases
2020-05-06T12:32:11 < azonenberg> So i think i'll just have current limiting and negotiate the power via a normal usb 2.0 control endpoint
2020-05-06T12:32:36 < azonenberg> and then if power is applied and the device doesn't see power after 100ms or so, it will complain to the host and say your cable is wrong
2020-05-06T12:33:43 < azonenberg> So basically the only nonstandard bit is that i'm negotiating the alternate mode via the usb2.0 channel and not the PD channel
2020-05-06T12:34:01 < azonenberg> Because there don't seem to be any good cheap micros like stm32 that have PD host capability
2020-05-06T12:34:52 < jpa-> looks like USB standard requires AC coupling only on the TX side of the superspeed pairs, so if you feed 7V into a receiver it could damage it
2020-05-06T12:35:13 < azonenberg> So maybe i'll do a staged rampup
2020-05-06T12:35:20 < azonenberg> turn power on the TX pins first
2020-05-06T12:35:28 < azonenberg> if i don't see 7V come out the other side, don't enable the other rail
2020-05-06T12:37:02 < ds2> PD still seems to be the better way of negotiating it
2020-05-06T12:37:11 < ds2> use the vendor specific commands
2020-05-06T12:37:15 < azonenberg> so what would you suggest for doing a proper usb alt mode?
2020-05-06T12:37:18 < azonenberg> any chipsets to suggest?
2020-05-06T12:37:19 < jpa-> ds2: how is it better?
2020-05-06T12:37:31 < ds2> jpa-: that's how everything else is negotiated
2020-05-06T12:37:33 < azonenberg> i mean it's the more usb compliant option for sure
2020-05-06T12:37:47 < ds2> more specifically, the CC lines
2020-05-06T12:37:49 < jpa-> ds2: sure, but when doing custom stuff, who cares, nothing is going to interoperate with it anyway
2020-05-06T12:37:54 < ds2> it is a 1 wire serial bus
2020-05-06T12:38:16 < azonenberg> ds2: exactly
2020-05-06T12:38:18 < ds2> until it gets dropped on someone else 
2020-05-06T12:38:24 < azonenberg> idk if you missed the context but this is an oscilloscope-to-probe connection
2020-05-06T12:38:36 < azonenberg> there is no conceivable reason why anyone would want to plug an active scope probe into a laptop or phone
2020-05-06T12:38:48 < azonenberg> all i need to do is make sure if you mix up the cables you won't kill anything
2020-05-06T12:38:52 < azonenberg> functionality is not required
2020-05-06T12:39:02 < ds2> USB-C is so symmetrical, who knows what gets plugged to what
2020-05-06T12:39:12 < azonenberg> ds2: My proposed alt pinout is mirror capable
2020-05-06T12:39:25 < azonenberg> use both of the SSTX pairs for +7VDC and both of the SSRX for -7VDC
2020-05-06T12:39:33 < ds2> using the CC lines means you have should be safe... altmode is negotiated there normally
2020-05-06T12:39:49 < azonenberg> yes, but last time i looked into the usb pd protocol i didn't see any good host chipsets
2020-05-06T12:39:55 < azonenberg> everyone assumed you had a fancy cortex-a apps processor or something
2020-05-06T12:40:05 < ds2> hmm? 
2020-05-06T12:40:07 < azonenberg> you can get trivial PD peripheral chipsets that negotiate power and/or an alt mode for pennies
2020-05-06T12:40:14 < jpa-> ds2: do active cables block CC line altmode negotiation or how does it work?
2020-05-06T12:40:17 < ds2> the CC line can be done with a STM32
2020-05-06T12:40:24 < azonenberg> ds2: you're suggesting i bitbang the PD protocol?
2020-05-06T12:41:09 < ds2> jpa-: no... IIRC - active cables contain a prom on there so it can be interogated for more details but otherwise CC continues as normal
2020-05-06T12:41:25 < ds2> azonenberg: sure... someone else on this channel is doing something along those lines
2020-05-06T12:41:41 < azonenberg> Hmmm
2020-05-06T12:42:03 < ds2> the CC lines allow you to advertise abilities
2020-05-06T12:42:13 < ds2> and it has provisions for vendor commands
2020-05-06T12:42:38 < azonenberg> yeah i just recall the protocol stack being incredibly complex
2020-05-06T12:42:38 < Thorn> azonenberg stm32g have phy level support of PD, + they have X-CUBE-USB-PD which implements the logical level
2020-05-06T12:42:55 < azonenberg> Thorn: is the PD protocol symmetric host/device?
2020-05-06T12:42:59 < Thorn> the latter works with On Semi PD chips if you don't use g
2020-05-06T12:43:01 < azonenberg> i.e. a stm32g could be a PD host or device?
2020-05-06T12:43:15 < azonenberg> at the phy layer at least
2020-05-06T12:43:19 < Thorn> azonenberg ufp, dfp, drd, all of ot afaik
2020-05-06T12:43:35 < azonenberg> Hmm interesting 
2020-05-06T12:44:07 < azonenberg> (the other thing i'm trying to avoid is needing to jump through the hoops of joining USB-IF and getting certification, since interop with third party devices was never a goal)
2020-05-06T12:46:08 < ds2> thought the USB-IF is only for the logo
2020-05-06T12:46:22 < Thorn> I don't believe usb certification is mandatory to sell stuff legally
2020-05-06T12:46:23 < azonenberg> ds2: well i still have to get hold of the PD spec... :p
2020-05-06T12:46:28 < azonenberg> is that public?
2020-05-06T12:46:31 < Thorn> it's available
2020-05-06T12:46:34 < jpa-> usb specs are public
2020-05-06T12:46:35 < ds2> yes it is
2020-05-06T12:46:36 < azonenberg> And how about vid/pid's etc?
2020-05-06T12:46:39 < ds2> USB is a nice org
2020-05-06T12:46:44 < ds2> the bastards are MIPI
2020-05-06T12:46:47 < Thorn> the license says "for evaluation only"though lol
2020-05-06T12:46:48 < azonenberg> Lol
2020-05-06T12:47:24 < Thorn> azonenberg make sure to read the type c spec first, then pd
2020-05-06T12:47:36 < jpa-> IIRC you can get VID/PID for STM32 stuff from ST, or you for open source hw you can get from openmoko
2020-05-06T12:49:46 < azonenberg> Right now i'm just trying to figure out hardware requirements. My plan was to build a dev platform with two MCUs, two usb-c ports, some power fets and dc-dc modules, etc
2020-05-06T12:49:56 < azonenberg> and then start doing actual testing on that

2020-05-06T12:50:34 < jpa-> usb-c for probe connectors is actually a quite nice idea
2020-05-06T12:51:07 < azonenberg> The overall form factor of the planned scope is a 1U headless appliance with a small touch LCD for IP address configuration
2020-05-06T12:51:39 < azonenberg> a stm32f7 and FPGA on the mainboard, the f7 will run the LCD and SCPI interface and control all of the dacs and attenuators in the frontends
2020-05-06T12:52:01 < azonenberg> while the FPGA is a pure data-plane element that handles the DDR3 and 1/10G Ethernet interface, pulls waveforms off the ADCs, shoves them into RAM, then out the waveform socket
2020-05-06T12:52:09 < azonenberg> it also is in charge of managing triggers etc
2020-05-06T12:52:09 < Thorn> s/f7/g4/
2020-05-06T12:52:26 < azonenberg> no, there will be a g4 or so per port on the front panel for running the PD stuff
2020-05-06T12:52:35 < azonenberg> one per usb-c host interface, 8 channels so 8 g4's
2020-05-06T12:52:53 < Thorn> iirc it has 2 PD controllers
2020-05-06T12:53:12 < azonenberg> Thorn: does it have two usb controllers too though?
2020-05-06T12:53:26 < azonenberg> otherwise i'd need to have a hub chipset which adds more complexity and noise in close proximity to sensitive analog etc
2020-05-06T12:53:35 < azonenberg> i want to have as little digital stuff near the frontend as i can
2020-05-06T12:54:05 < azonenberg> there will probably be emi cans and all sorts of stuff

2020-05-06T12:57:42 < azonenberg> they are PD *only*, no actual USB
2020-05-06T12:57:58 < azonenberg> but i guess i could use PD to negotiate an alt mode and then run I2C or something over the sideband interface?
2020-05-06T12:58:18 < Thorn> g4 seems to only have 1 pd controller, not sure where I got that from

2020-05-06T13:08:33 < azonenberg> Nice
2020-05-06T13:08:57 < azonenberg> yeah i'm gonna have to play around a bit but i think this might be the way to go
2020-05-06T13:09:48 < zyp> I'm not sure exactly what of that is necessary/useful in an actual project, so I did this as a cheap design to try it out
2020-05-06T13:10:21 < zyp> while also allowing me to easily add usb ports to a fpga
2020-05-06T13:11:59 < azonenberg> makes sense
2020-05-06T13:13:04 < zyp> there's also a bunch of other PD port controllers, they apparently talk a standardized i2c interface and often includes a varying number of power switches
2020-05-06T13:13:24 < azonenberg> yeah but my use case (multiple power rails in alt mode) is a bit unique
2020-05-06T13:13:29 < azonenberg> i wasnt expecting to find an asic that did it
2020-05-06T13:13:33 < azonenberg> i figured code would be needed
2020-05-06T13:13:34 < zyp> e.g. TUSB422 includes the vconn switches
2020-05-06T13:13:54 < zyp> multiple power rails?
2020-05-06T13:14:15 < zyp> as in several choices of vbus voltage?
2020-05-06T13:14:21 < azonenberg> no as in two simultaneous voltages
2020-05-06T13:14:29 < zyp> oh, on data lines?
2020-05-06T13:14:37 < azonenberg> I'm trying to make an alt mode with +7VDC on SSTX and -7VDC on SSRX to power an active scope probe
2020-05-06T13:14:48 < azonenberg> while using either PD, SBU, or USB2 data lines for gain/offset controls
2020-05-06T13:14:49 < zyp> ah
2020-05-06T13:15:55 < zyp> well, if I understand those port controllers right, they just act as a mac/phy for the PD messages, they don't interpret them
2020-05-06T13:16:15 < zyp> I mean, assuming you don't look at standalone port controllers, they also exist
2020-05-06T13:18:58 < zyp> I figure the g071 and those external switches I've got for vconn should be fairly equivalent in capability to an arbitrary mcu paired with a tusb422
2020-05-06T13:19:53 < zyp> and either way you'll negotiate a vendor proprietary mode before you switch on the extra power rails

2020-05-06T14:06:51 < azonenberg> jadew: meanwhile i've got a board in shenzhen that hasn't moved from the fedex warehouse since the 29th
2020-05-06T14:07:37 < jadew> azonenberg, I assume that's about when my boards were shipped too, because they're marked as shipped but I didn't get any info on tracking number and DHL hasn't called me yet to ask me for money
2020-05-06T14:07:45 < azonenberg> this is fedex
2020-05-06T14:07:45 < jadew> so I assume they're still there
2020-05-06T14:07:52 < azonenberg> This fab has always shipped via DHL until the virus hit
2020-05-06T14:07:58 < azonenberg> they did my last one via ups, this one via fedex
2020-05-06T14:08:07 < azonenberg> sounds like they're trying to find a carrier that's hit less bad and not having much luck
2020-05-06T14:08:29 < jadew> hmm
2020-05-06T14:08:46 < jadew> I got something else from china via DHL, right after the lockdown was lifted there
2020-05-06T14:08:52 < jadew> got here quite fast
2020-05-06T14:09:01 < jadew> I still haven't opened it

2020-05-06T14:53:25 < Steffanx> Gooday Thorn

2020-05-06T14:53:51 < dongs> arent theyt all installed by default
2020-05-06T14:53:54 < dongs> why do you need to add more

2020-05-06T16:04:51 < BrainDamage> one of human's favourite activities is telling others how to live their life
2020-05-06T16:11:55 < PaulFertser> But it's not about just their lifes, it's about the child too, who can't decide or defend itself on its own.
2020-05-06T16:13:17 < mawk> don't you think society should maximize total society happiness in a particular way BrainDamage ?
2020-05-06T16:15:46 < PaulFertser> You realise where that's going though? Italian and Russian people have quite some experience in "maximizing total happiness"...
2020-05-06T16:16:30 < PaulFertser> Where to draw the line? And how to secure it there?
2020-05-06T16:16:32 < BrainDamage> I don't think that child will have a decent childhood, but the name is just a symptom
2020-05-06T16:17:17 < mawk> yeah that's why I said particular PaulFertser 
2020-05-06T16:17:25 < mawk> but what other goal could you set
2020-05-06T16:17:31 < mawk> you can't say maximizing total despair
2020-05-06T16:17:48 < mawk> you could say maximize the number of happy individuals
2020-05-06T16:17:52 < mawk> then it's alright
2020-05-06T16:18:32 < BrainDamage> I do believe that the state should make its citizens happiness, but it should do it in the most unobtrusive way possible
2020-05-06T16:18:34 < PaulFertser> How about maximizing mean level of individual freedom?
2020-05-06T16:19:14 < BrainDamage> and drawing the line is exactly the hard part
2020-05-06T16:19:46 < BrainDamage> even though it can be blatant to point at once you've crossed it, making a formal general rule isn't easy
2020-05-06T16:19:54 < PaulFertser> Assuming that "criminals" are decreasing the freedom levels of the others so the society needs to somehow regulate that kind of activities.
2020-05-06T16:21:36 < zyp> PaulFertser, how would that tie into dealing with climate change?
2020-05-06T16:25:36 < PaulFertser> zyp: free people will realise the dangers and exercises their freedoms to make a colloborative effort :)
2020-05-06T16:26:04 < zyp> yeah, right
2020-05-06T16:26:23 < qyx> except they won't
2020-05-06T16:27:28 < mawk> if you did a referendum about taking action against climate change, the outcome could be positive
2020-05-06T16:28:11 < mawk> and if you say you must maximize happiness not only for the current time, but for society as a whole even in the future, then it's obvious

2020-05-06T21:35:48 < logicp> Does anyone know if the X-Nucleo motor expansion boards are compatible with STM32 Nucleo 144 boards?
2020-05-06T21:36:56 < logicp> the X-Nucleo products claim to be compatible with the Arduino R3 connector, but I'm finding that, though the Nucleo 144 boards claim to have this connector, the pins critical to utilize the X-Nucleo's functionality are not aligned between the X-Nucleo and Nucleo 144
2020-05-06T21:39:40 < catphish> i thought the arduino pins never changed
2020-05-06T21:41:08 < logicp> that would make sense.. I'm a bit of a n00b.. but when I look at the X-Nucleo's datasheet, it claims to use D9 as a "Standby/Reset", and D9, on the 144, maps to a pin which doesn't make contact with the X Nucleo board
2020-05-06T21:41:25 < logicp> the X Nucleo, however, does fit perfectly (physically speaking) onto the 144 board
2020-05-06T21:41:46 < logicp> so I'm thinking that maybe I just need to examine what D5 is on the X-Nucleo, and find the corresponding pin on the 144
2020-05-06T21:42:10 < logicp> I was just hesitant because I assumed that the mapping wouldn't, as you stated, change

2020-05-06T21:43:36 < logicp> hmm on further inspection it seems that I'm being thrown off by the Nucleo144 User Manual
2020-05-06T21:43:53 < logicp> it claims that D9, fo rexample, maps to a pin which isn't making contact between the boards
2020-05-06T21:44:07 < logicp> but when I look at the top of the 144 board, I do see "D9", and it is connecting with the XNucleo
2020-05-06T21:44:34 < logicp> it just doesn't map to the STM32 pin claimed in the User Manual
2020-05-06T21:44:39 < logicp> I guess I don't understand the mapping in the Manual, then
2020-05-06T21:44:49 < Steffanx> I used a motor expansion board once, but i dont recall what nucleo i used.
2020-05-06T21:44:57 < catphish> it's good to double check!
2020-05-06T21:45:06 < catphish> the datasheet knows better than i do
2020-05-06T21:45:19 < Steffanx> did you look into the schematics?
2020-05-06T21:45:51 < catphish> it won't always be the same PORT/PIN on the STM32 that goes to the same arduino pin
2020-05-06T21:45:53 < Thorn> so, according to my research, c++20 coroutines are not the only ones unavailable on cortex-m (yet, waiting for gcc 10). boost asio coroutines aren't available either because boost.context has not been ported to cortex-m
2020-05-06T21:46:16 < catphish> it will just be *a* pin that is able to provide the necessary arduino function
2020-05-06T21:47:01 < logicp> schematics no.. my n00bularity sometimes confuses me about which diagrams/reference to prioritize
2020-05-06T21:47:11 < logicp> it does seem that there is a connection, however.. so I think this should be safe to test
2020-05-06T21:47:29 < Steffanx> and if it doesnt you can blog about it for the world.
2020-05-06T21:47:31 < logicp> unfortunately it seems one of my expansion boards doesn't fit though.. maybe i can just wire the thing LOL
2020-05-06T21:47:33 < logicp> haha yes indeed
2020-05-06T21:47:49 < logicp> maybe I can make a video where it catches on fire

2020-05-07T03:56:18 < nn7> corrupted
2020-05-07T03:56:52 < nn7> If I delay for half the time it takes to send the transmission, only half of the transmission gets corrupted.
2020-05-07T04:00:00 < Cracki> what do these peripherals share
2020-05-07T04:00:29 < nn7> HAL?
2020-05-07T04:00:45 < Cracki> do they share interrupts
2020-05-07T04:00:51 < Cracki> does the hal share buffer space between them
2020-05-07T04:00:54 < nn7> The SPI is done in blocking mode
2020-05-07T04:01:05 < nn7> I don't know how to tell if they share buffer space.
2020-05-07T04:01:25 < nn7> You mean in my code or in the HAL?

2020-05-07T08:30:08 < Cracki> sigrok gained a project that acts like a scope view https://knarfs.github.io/doc/smuview/0.0.4/manual.html
2020-05-07T08:31:29 < srk> cool
2020-05-07T08:31:41 < srk> qt, not bad
2020-05-07T08:33:58 < Cracki> and then there's this beast https://sigrok.org/wiki/CoLA
2020-05-07T08:34:09 < Cracki> (I'm browsing the picture uploads of the wiki)
2020-05-07T08:41:53 < srk> w00t
2020-05-07T08:41:56 < srk> solid LA
2020-05-07T08:42:15 < Cracki> and now I find this madness which seems to be decades old magic https://sigrok.org/wiki/Protocol_decoder:Signature
2020-05-07T08:42:49 < srk> lol
2020-05-07T08:43:00 < srk> just finished fixing hp z420 mobo :D
2020-05-07T08:43:18 < srk> bet there's some of that on it
2020-05-07T08:43:23 < Cracki> PD source says it's a kind of checksum that's calculated on the data
2020-05-07T08:44:28 < srk> PD?
2020-05-07T08:44:36 < Cracki> protocol decoder
2020-05-07T08:44:39 < srk> ah
2020-05-07T08:44:40 < Cracki> sigrok lingo
2020-05-07T08:44:49 < srk> yeah, I've been using them for a while 
2020-05-07T08:44:54 < srk> early mornin' :)
2020-05-07T08:45:01 < srk> pure data came to my mind first :D
2020-05-07T08:45:53 < Cracki> this could use a little more commenting. https://sigrok.org/gitweb/?p=libsigrokdecode.git;a=blob;f=decoders/signature/pd.py;h=946b2da7574e7fb4b01e0caeb0d584fa1dee1ff5;hb=HEAD
2020-05-07T08:46:12 < srk> Intel/Altera 5CEBA5F23C8N
2020-05-07T08:46:16 < Cracki> the checksum is tapping the register, xoring those bits and the input, and shifting
2020-05-07T08:46:31 < Cracki> "linear feedback shift register" it seems to be called
2020-05-07T08:46:32 < srk> but there's even verilog for it, can you buy CoLA already?
2020-05-07T08:46:45 < Cracki> no clue, I'm just browsing the wiki :>
2020-05-07T08:46:48 < srk> :D
2020-05-07T08:46:59 < srk> like it's been a while since I needed LA but still
2020-05-07T08:47:31 < srk> something like that with open toolchain fpga gonna be killer board
2020-05-07T08:48:02 < Cracki> that "open logic sniffer" thing seems abandoned
2020-05-07T08:48:47 < srk> ols wasn't bad at all but not ideal
2020-05-07T08:49:15 < srk> there were some alt firmwares for it, to even do continous capture I think, not sure
2020-05-07T08:49:22 < srk> or JTAG..
2020-05-07T08:49:33 < srk> but reflashing it for different purposes with .bin files is not ideal
2020-05-07T08:50:21 < Cracki> fx2lafw does a similar thing, except not to flash but ram, I think
2020-05-07T08:51:24 < srk> wanted to buy that one
2020-05-07T08:51:53 < Cracki> fx2? those are 5 bucks I have a few
2020-05-07T08:52:14 < Cracki> ah you must mean OLS
2020-05-07T08:52:18 < srk> no no
2020-05-07T08:52:22 < srk> fx2
2020-05-07T08:52:27 < srk> we've bought ols years ago
2020-05-07T08:52:41 < srk> it's a bit dated now :)
2020-05-07T08:52:41 < Cracki> boss has an ols too, seems fried/shorted
2020-05-07T08:52:49 < srk> :D
2020-05-07T08:53:03 < Cracki> fx2 is so dirt cheap I'd pass them out like candy
2020-05-07T08:53:32 < Cracki> great loot if you're having a booth at a trade fair
2020-05-07T08:54:11 < srk> can you recommend one?
2020-05-07T08:54:42 < srk> like I could use spartan 6 for that but the toolchain..
2020-05-07T08:55:01 < Cracki> aliex has either a breakout board, which you can use for 16 ch 12 MHz, or they have those in the little cases that I find very convenient
2020-05-07T08:55:11 < Cracki> https://www.aliexpress.com/wholesale?catId=0&initiative_id=SB_20200506215505&SearchText=8ch+24m
2020-05-07T08:55:31 < Cracki> by 'fx2" i mean those things, not the fx2lp chip itself
2020-05-07T08:56:37 < srk> yeah, figured
2020-05-07T08:56:43 < Cracki> something made me buy a 34ch 125 mhz LA some chinaman on aliexpress made. I think it uses a spartan 6. he calls himself "sysclk" and sigrok actually supports/suported it
2020-05-07T08:56:45 < srk> this has a nice list too https://sigrok.org/wiki/Fx2lafw
2020-05-07T08:56:59 < srk> oO nice
2020-05-07T08:57:25 < srk> when I grow up I'll build https://www.bunniestudios.com/blog/?p=3957
2020-05-07T08:57:27 < Cracki> that thing https://sigrok.org/wiki/Sysclk_LWLA1034
2020-05-07T08:57:38 < Cracki> heh
2020-05-07T08:57:55 < srk> and LA on top of that :D

2020-05-07T12:31:02 < Cracki> catphish, iirc you handled miller encoding for the floppy drive project, is that right? I'm wondering if the first symbol is a 0 or 1. in both cases (phase shift), a valid signal decodes according to the rules
2020-05-07T12:31:58 < Cracki> I couldn't find anywhere that says this, and it needs to be specified because both ways to decode a signal aren't just bit flips of each other
2020-05-07T12:32:02 < catphish> Cracki: i did, yes, but i don't underdtand your question
2020-05-07T12:32:18 < Cracki> gaze upon this signal https://sigrok.org/wimg/7/75/PD_miller.png
2020-05-07T12:32:25 < Cracki> (it's modified miller, edges turn into pulses)
2020-05-07T12:32:43 < Cracki> now, if the first symbol is defined to be a 1, this would still decode
2020-05-07T12:33:25 < Cracki> because edges/pulses come every 1.0, 1.5, 2.0 periods
2020-05-07T12:34:38 < catphish> is your concern about where the signal begins?
2020-05-07T12:35:03 < Cracki> yes
2020-05-07T12:35:06 < catphish> if so, that's a problem that has to be solved separately from the encoding itself
2020-05-07T12:35:10 < Cracki> ic
2020-05-07T12:35:37 < Cracki> so... a decoder would need to be told whether first symbol is 0 or 1?
2020-05-07T12:35:51 < Cracki> I guess I have to make a pull request then
2020-05-07T12:36:26 < Cracki> how does floppy do it?
2020-05-07T12:36:48 < catphish> usually you would have a lead-in (101010101010) for an arbitrary amount of time to sync clocks between the transmitter and receiver, followed by a known fixed value (sync byte)
2020-05-07T12:37:05 < catphish> have a look at http://lclevy.free.fr/adflib/adf_info.html#p23
2020-05-07T12:37:20 < Cracki> thx I remembered that page but hadn't bookmarked it
2020-05-07T12:37:35 < catphish> amiga uses 0xAAAAAAAA followed by 0x44894489
2020-05-07T12:38:10 < catphish> AAAAAAAA is magic because it's just a square wave, and 0x44894489 is magic because it's not actually valid MFM and hence will never appear in the data
2020-05-07T12:38:34 < catphish> but together, they can be used to lock so the start of the signal
2020-05-07T12:38:35 < Cracki> 4489 = 0b100010010001001
2020-05-07T12:40:00 < catphish> i went through it once, and iirc 4489 is slightly different from how any real data would be encoded
2020-05-07T12:40:09 < Cracki> I think that's valid, it has 2.0, 1.5, and 1.0 intervals between edges
2020-05-07T12:40:20 < catphish> yes, it's valid in that way
2020-05-07T12:40:36 < catphish> but no data would be encoded that way, most likely it has a clock inverted somewhere
2020-05-07T12:40:38 < Cracki> ok
2020-05-07T12:41:13 < Cracki> page says 0x4489 encodes 0xA1
2020-05-07T12:41:34 < Cracki> does it call for escaping or bit stuffing anywhere?
2020-05-07T12:41:37 < catphish> yeah, it does, but if you actually encode A1 i believe you get something subtly different
2020-05-07T12:41:49 < Cracki> or does it require quiet time before the sync pattern
2020-05-07T12:43:15 < catphish> the disks i was working with just require 44894489 and some period of square wave immediately before for clock locking
2020-05-07T12:45:07 < Cracki> I'm asking because miller/modified miller is used with nfc too, and I haven't found anything specific at all so far, no mention of sync patterns or anything
2020-05-07T12:45:11 < Cracki> I guess I'll keep digging
2020-05-07T12:46:01 < catphish> so, 0xA1 normally encodes to 01000100 10101001 but 0x4489 is actually 01000100 10001001
2020-05-07T12:46:24 < Cracki> both aaaa (00) and 4489 (a1) start with a 0-bit so that's comforting
2020-05-07T12:46:37 < Cracki> hm wait, a1 doesn't start with a 0 bit, what am I seeing
2020-05-07T12:46:37 < catphish> it maintains the required intervals but... there's a single bit inverted, which mean its not real data and hence a useful start byte
2020-05-07T12:46:52 < Cracki> eh, didn't see the leading 0 of 4489, oh well
2020-05-07T12:47:23 < Cracki> huh curious
2020-05-07T12:49:43 < Cracki> NOW i see where 4489 is invalid
2020-05-07T12:49:46 < catphish> anyway since my code has no need for clock syncronization, i just listen until i hear 44894489 then assume the data immediately follows
2020-05-07T12:50:02 < Cracki> bit 0 is 00 in there, when it should be 10 because it follows another 0
2020-05-07T12:50:06 < catphish> correct :)
2020-05-07T12:50:36 < catphish> this is amiga proprietary, but other systems have similar methods
2020-05-07T12:51:36 < catphish> remember that this system is designed to be distinguishable from noise, not from silence
2020-05-07T12:51:55 < catphish> so you can't just assume that the first bit you receive is the start of the data
2020-05-07T12:52:14 < Cracki> ah finally, the pictures imply that the start bit is a 0 (10) http://blog.rona.fr/post/2017/10/15/Sniffing-and-decoding-NFC-with-a-DVB-T-stick-rtl-sdr-and-GNURadio
2020-05-07T12:52:30 < Cracki> true true
2020-05-07T12:52:35 < catphish> it's not like RS232 where the line is quiet between valid data, it's designed for a floppy disk, where new data is written over old data
2020-05-07T12:52:43 < Cracki> auto gain yes
2020-05-07T12:52:44 < catphish> so immediately before the data will be junk old data
2020-05-07T12:52:50 < Cracki> and that
2020-05-07T12:53:39 < catphish> but yes, for radio this would be useful because AGC, this is also why the maximum length between pulses is 2.0
2020-05-07T12:53:46 < catphish> because it keeps the gain and clock in sync

2020-05-07T16:32:45 < zyp> (hubs are required for standard enumeration, to ensure there's only one connected device with address 0 at a time, so when enumerating the whole tree, only one port is turned on at a time)

2020-05-07T16:53:47 < PaulFertser> I was fooled by reading "shared media" while they meant single pair for full duplex.
2020-05-07T16:58:25 < zyp> it'd be perfect otherwise
2020-05-07T16:59:18 < zyp> as it is, it's still kinda interesting, but when I looked at it, all the switches seems to be under NDA
2020-05-07T16:59:52 < PaulFertser> I wouldn't be surprised if it would still work with appropriate termination or some such.

2020-05-07T17:11:36 < dongs> have you started? or still doing sch
2020-05-07T17:11:50 < dongs> it takes all teh fucking wrong decisions for trace position EVERY. FUCKING. TIME.
2020-05-07T17:11:59 < dongs> i have to fight with the fucking thing routing every trace
2020-05-07T17:14:36 < zyp> apparently 10BASE-T1S is a thing too

2020-05-07T17:25:26 < zyp> yes
2020-05-07T17:26:23 < Cracki> is that bus supposed to be multi master and realtime?

2020-05-07T18:41:48 < nn7> Well, I'm confused. It seems that many things can corrupt the UART_Transmit_IT data.
2020-05-07T18:41:57 < dongs> no, your shit is broken
2020-05-07T18:42:19 < nn7> Yes. Yes it is.
2020-05-07T18:43:52 < nn7> Could it be that I'm not using a global variable as my buffer and the data is being discarded before it's used?
2020-05-07T18:44:11 < dongs> uh, where is the buffer?
2020-05-07T18:44:14 < dongs> on thread stack? lol
2020-05-07T18:46:03 < nn7> https://pastebin.com/ZVmjWWFc
2020-05-07T18:46:23 < dongs> .
2020-05-07T18:46:26 < dongs> r u for real
2020-05-07T18:46:33 < dongs> yeah, that is the problem
2020-05-07T18:46:33 < nn7> please explain
2020-05-07T18:46:40 < nn7> really?! 
2020-05-07T18:46:42 < dongs> the buffer is on stack
2020-05-07T18:46:48 < dongs> its gone as soon as you exit out of transmit_IT
2020-05-07T18:47:00 < dongs> but you don't actually get callback long after function is exited and gone
2020-05-07T18:47:14 < zyp> as soon as you return from Send_Command_To_Net() actually, but yeah
2020-05-07T18:47:23 < zyp> that happens at the same time
2020-05-07T18:47:23 < dongs> well thats waht i meant
2020-05-07T18:47:40 < nn7> It gets corrupted if one of my other routines fires, but works fine if the processor is mostly idle
2020-05-07T18:47:45 < zyp> dongs, good guess
2020-05-07T18:47:50 < nn7> I'm really excited that I figured that out.
2020-05-07T18:48:07 < dongs> you mean pro EEs on IRC figured it out for ya
2020-05-07T18:48:16 < nn7> so... just declare a global and store it in there?
2020-05-07T18:48:37 < dongs> you could make it static inside the function
2020-05-07T18:48:45 < dongs> if you wanna keep it neat
2020-05-07T18:48:53 < dongs> but idk how that goes with the rest of your code.
2020-05-07T18:49:07 < dongs> i dont know how the HAL_IT callback looks like either
2020-05-07T18:49:09 < nn7> I'm sorry, you're absolutely correct, dongs. Thank you very much for figuring that out for me.
2020-05-07T18:49:13 < dongs> do they give you back a pointer to the buffer you provided?
2020-05-07T18:49:54 < nn7> no
2020-05-07T18:50:43 < nn7> Can you tell me about this making it static?
2020-05-07T18:50:50 < zyp> dongs, I'm wondering about pcb pricing, I remember you quoted those LL 4L pcbs once some years ago, how does the price scale if I wanna do multiple layouts at once?
2020-05-07T18:50:56 < nn7> I don't understand any of this "static" stuff
2020-05-07T18:51:24 < zyp> nn7, maybe you should find some tutorials or articles on C about it?
2020-05-07T18:51:46 < PaulFertser> nn7: then read the book https://en.wikipedia.org/wiki/The_C_Programming_Language and learn about variable lifetime and visibility proper. It's kinda trivial in C.
2020-05-07T18:52:27 < dongs> zyp, up to 3 models
2020-05-07T18:52:34 < dongs> after that becomes dumb
2020-05-07T18:52:40 < zyp> nn7, the quick description is that a static function variable is equivalent to a global variable, just namespaced to a specific function
2020-05-07T18:52:41 < nn7> If it's static, and that code gets called repeatedly, does it keep consuming memory?
2020-05-07T18:52:48 < dongs> no
2020-05-07T18:52:55 < dongs> static is same as having it outside the function
2020-05-07T18:52:57 < dongs> as global
2020-05-07T18:53:05 < dongs> i mean, it goes into same memory region as globals
2020-05-07T18:53:24 < nn7> so when that function is called again, that variable space is just reused?
2020-05-07T18:54:56 < zyp> https://paste.jvnv.net/view/VPCT0 <- these two functions are equivalent, the only difference is that on the second one, foo is not visible outside the function
2020-05-07T18:55:13 < dongs> this isnt C zyp

2020-05-07T18:55:32 < dongs> (void) = C
2020-05-07T18:55:34 < zyp> because of the comment or because no (void)?
2020-05-07T18:55:38 < dongs> the latter yes

2020-05-07T18:57:30 < nn7> Woot! Dongs saved my program. Thanks again, dongs!
2020-05-07T18:59:07 < zyp> dongs, I'm aware of the difference, but why does it matter? what do you gain from explicitly stating that the function takes no arguments?
2020-05-07T18:59:17 < dongs> zyp, it doesnt look dumb
2020-05-07T18:59:20 < dongs> () just looks wrong
2020-05-07T18:59:53 < zyp> except it's right in every other language
2020-05-07T19:00:06 < dongs> if only every other language mattered

2020-05-07T19:03:15 < PaulFertser> zyp: if your function prototype has () and you try calling it with an argument the compiler won't raise an error.
2020-05-07T19:03:42 < PaulFertser> In C
2020-05-07T19:04:05 < emeb> yes - (void) gives the compiler more clues about what you want and generates helpful warnings.

2020-05-07T19:10:23 < zyp> warnings, sure, but I don't see how the actual generated code would differ
2020-05-07T19:11:09 < PaulFertser> Other languages were developed later and so can really treat () to mean a nullary function rather than something of arbitrary arity like C does for backwards compatibility.
2020-05-07T19:12:20 < PaulFertser> zyp: good thing about (void) is that the code in the case you try to call it wrong won't be generated at all. So one can say the generated code would differ in a way.

2020-05-07T20:27:23 < nn7> Cracki, I moved from ATMega as well.
2020-05-07T20:29:52 < nn7> I've identified the name of a register that I want to check. Where do I figure out what it takes to access that register?
2020-05-07T20:31:13 < nn7> I don't know where I would start to look to determine this information on my own.
2020-05-07T20:39:03 < PaulFertser> Where would you be looking for such information with an atmega?
2020-05-07T20:39:18 < nn7> The datasheet.
2020-05-07T20:39:32 < PaulFertser> nn7: usually one is using a library and it has all the memory-mapped registers defined for easy access.
2020-05-07T20:39:46 < nn7> I think it's part of CMSIS
2020-05-07T20:39:49 < PaulFertser> So if you know the register name you probably can just use it.
2020-05-07T20:39:56 < PaulFertser> I think CMSIS is ARM generic.
2020-05-07T20:40:09 < PaulFertser> Are you looking for something stm32 specific?
2020-05-07T20:40:12 < nn7> I tried just using DHCSR but it was undefined.
2020-05-07T20:40:29 < nn7> It's in the ARM manuals so I think it's generic.
2020-05-07T20:40:47 < PaulFertser> Yeah. Why do you need it btw?
2020-05-07T20:41:16 < PaulFertser> You have its address from http://infocenter.arm.com/help/topic/com.arm.doc.ddi0337e/CEGCJAHJ.html or other ARM docs.
2020-05-07T20:41:42 < PaulFertser> So you can probably access it like *(uint32_t*)0xE000EDF0
2020-05-07T20:42:10 < nn7> My code doesn't run if the debugger isn't connected. I think it's due to my _write function calling ITM_SendChar so I'm trying to determine if the debugger is connected before attempting to write data to the ITM
2020-05-07T20:42:11 < PaulFertser> And I'd also grep through all the library you're using, probably it's already defined but has some other name.
2020-05-07T20:42:24 < PaulFertser> Makes sense
2020-05-07T20:42:54 < nn7> But I decided to go back to just commenting out the ITM_SendChar command and the code still doesn't run, so maybe my problem is elsewhere.
2020-05-07T20:43:11 < PaulFertser> nn7: might be called SCB_DHCSR
2020-05-07T20:44:06 < nn7> There's an scb_base but no scb_dhcsr. Bummer
2020-05-07T20:44:33 < PaulFertser> nn7: but it's not doing https://github.com/ARM-software/CMSIS/blob/6891719834ac6ca2a79e8ded00620faffae10ae8/CMSIS/Include/core_cm3.h#L1698 anything when ITM is disabled. So if you enable it only from the debugger side it should be OK.
2020-05-07T20:45:09 < PaulFertser> You're supposed to let the debugger enable ITM and the channels/ports the user wants.  
2020-05-07T20:45:38 < nn7> Hmm.. ok
2020-05-07T20:45:58 < nn7> So it looks like my code is locking up elsewhere.

2020-05-07T20:47:14 < nn7> Actually even with the debugger plugged in it doesn't run. Only when I flash new code.
2020-05-07T20:47:27 < nn7> The boot jumper isn't in.
2020-05-07T20:48:31 < nn7> PC is at 0x8008108
2020-05-07T20:49:24 < PaulFertser> So with debugger attached to "reset halt" and then step by instruction and see what it does.
2020-05-07T20:49:33 < PaulFertser> Check PC and SP and what instructions are running.
2020-05-07T20:50:52 < nn7> I have PSP and MSP but not just SP.
2020-05-07T20:51:29 < nn7> I seem to be in some loop in 0x8005Exx
2020-05-07T20:51:41 < PaulFertser> Probably BSS cleanup
2020-05-07T20:52:01 < PaulFertser> Can you load elf and see source code?
2020-05-07T20:52:21 < nn7> uhhh....
2020-05-07T20:52:31 < nn7> I don't know. I'm using the STM32 ST-LINK Utility right now
2020-05-07T20:53:20 < nn7> When I pull power and plug it back in, chip goes to 0x8008108 
2020-05-07T20:53:46 < PaulFertser> Well you have ability to do full debug with breakpoints watchpoints and whatever, stepping through C code and yet you're using the shitty utility...
2020-05-07T20:53:47 < nn7> which isn't in the list of device memory
2020-05-07T20:54:09 < nn7> If I run the program in the debugger it runs with no problems. 
2020-05-07T20:54:16 < PaulFertser> nn7: is your code linked to run from 0x08000000 ? It's the usual place flash is mapped to on stm32.
2020-05-07T20:54:50 < nn7> My code was compiled and flashed by STM32CubeIDE so my assumption is that it knows what it's doing.
2020-05-07T20:56:54 < nn7> What I would like is a way to connect the debugger with STM32CubeIDE but the only way I know to do that is to run the debug process which flashes the code, and then the code runs fine.

2020-05-07T21:07:39 < nn7> is this just the default breakpoint at the beginning?
2020-05-07T21:07:48 < nn7> does that get written in when flashed?
2020-05-07T21:09:13 < nn7> So I click the "run" button in STM32CUBEIDE, the code gets flashed and starts running in the stm32.
2020-05-07T21:09:25 < nn7> I power-cycle the board and the code doesn't run
2020-05-07T21:10:52 < nn7> Is it at the reset_handler because the code crashed or because it never started?
2020-05-07T21:10:55 < nn7> How would I know?
2020-05-07T21:11:49 < PaulFertser> nn7: I am using only OpenOCD, so can't tell how te debug using your tools, sorry.
2020-05-07T21:12:39 < nn7> well if I click "run" in the st-link utility, it seems to move on to other stuff, but doesn't outwardly show any sign of doing what it's supposed to do.
2020-05-07T21:12:59 < PaulFertser> Who and why usually uses "on the fritz" idiom? Is it not gay enough so I do not remember seeing it on this channel ever?
2020-05-07T21:14:54 < boddax_> i have fritz box router dsl
2020-05-07T21:15:18 < nn7> Hmm... looks like if I run the code and then start stepping, it's in a microsecond delay runction that checks DWT -> CYCCNT
2020-05-07T21:15:42 < PaulFertser> boddax_: is it constantly on the fritz though? I thought they're usually pretty reliable.
2020-05-07T21:16:50 < boddax_> dont know if the owner of fritz brand us a litle bit frau frau
2020-05-07T21:17:05 < nn7> Ah! that's it. It's Do {} while ((DWT->>CYCCNT - start) < cycles);
2020-05-07T21:25:58 < nn7> PaulFertser, I found the magic to accessing DHCSR is "CoreDebug->DHCSR"
2020-05-07T21:27:02 < PaulFertser> nn7: grepping through cmsis-dap should have revealed that.
2020-05-07T21:28:17 < nn7> And in order for the cycle counter to run, the TRCENA bit has to be set. Apparently the debugger does that for me, which is why the code only worked when the debugger was running.
2020-05-07T21:28:21 < nn7> YAY! Success!
2020-05-07T21:28:26 < nn7> Thanks PaulFertser!
2020-05-07T21:29:45 < PaulFertser> :)
2020-05-07T21:33:32 < nn7> Jeez that was an expensive find.

2020-05-07T22:40:20 < zyp> i3c is interesting since it provides an upgrade path from i2c
2020-05-07T22:41:02 < mawk> yeah
2020-05-07T22:41:46 < zyp> i.e. I can start with i2c now, and switch to i3c later for devices that needs more throughput

2020-05-07T22:50:37 < Thorn> which pin and which stm32 is it?

2020-05-07T22:54:30 < nn7> oh, just the reset jumper.
2020-05-07T22:55:43 < nn7> ok yeah, that's just system memory
2020-05-07T22:57:09 < zyp> qyx, i3c fast mode can coexist with i2c by using 40ns wide clock pulses that i2c devices with a 50ns spike filter will ignore
2020-05-07T22:57:46 < zyp> the latter seems to already be integrated in the newer stm32s, it's apparently mandated by one of the newer i2c specs
2020-05-07T22:59:16 < zyp> of course, coexisting is just the lowest form of compatibility, what I'm curious about is whether the i3c dynamic address assignment is designed in such a way that I can make i2c devices use it

2020-05-08T00:13:45 < nn7> name isn't a uint8_t. I guess you could argue that "*name" is a uint8_t but that may not be true.
2020-05-08T00:14:06 < qyx> yes and there are people writing function( param ) because they think it is more readable

2020-05-08T02:25:29 < strata> i have a bunch of starters already to go
2020-05-08T02:25:44 < kakinull> are these part of intentional plan?
2020-05-08T02:25:45 < strata> and last weekend i expanded gardens to almost 1/2 of the back yard
2020-05-08T02:25:54 < kakinull> *an intertional
2020-05-08T02:25:59 < kakinull> *international
2020-05-08T02:26:01 < strata> today i finished automating seed starting for my peppers
2020-05-08T02:26:38 < strata> i am thinking this will help for other plants too. peppers like to germinate in 75-80 degree soil temp
2020-05-08T02:27:20 < kakinull> why backrupt small business and then lift restrictions?
2020-05-08T02:28:25 < strata> if you don't know the answer already, you must wait.

2020-05-08T09:24:37 < PaulFertser> dongs: what would you do if you had an old equipment and needed to have it printing?
2020-05-08T09:27:58 < dongs> sure as fuck not use rageberrypi
2020-05-08T09:28:55 < PaulFertser> dongs: they say you can use any SBC
2020-05-08T09:30:04 < Cracki> uint8_t *foo, bar, *baz; // where is your god now
2020-05-08T09:32:03 < PaulFertser> dongs: seriously, what's wrong with that project other than saying that a raspberrypi can be used to interface that board?
2020-05-08T09:32:50 < dongs> PaulFertser: its 55gbp for a pcb with like 2 DIP parts on it. it uses a fucking sbc to do the conversion. its retarded, huge, and useless
2020-05-08T09:34:33 < PaulFertser> dongs: make your own cheaper, apparently there's a market for such converters. Plenty of old equipment out there, "such as data analysers, opthalmic equipment, test equipment and injection moulding machines"

2020-05-08T09:47:03 < upgrdman> can't even do 16 MSAA :(
2020-05-08T09:47:59 < Cracki> can't even play crysis in this thing, right?
2020-05-08T09:48:45 < upgrdman> actually just trying to get my TelemetryViewer working with it
2020-05-08T09:49:03 < upgrdman> so i can do some cross-platform JNI testing without needing a bunch of PCs
2020-05-08T09:49:04 < PaulFertser> dongs: for someone who runs opthalmic equipment and spends hundreds of dollars every year to keep the old dot-matrix printer functional sparing just 55 bucks once would be great deal.
2020-05-08T09:50:13 < Cracki> if it can't do MSAA the graphics just look less expensive? does it prevent operation?
2020-05-08T09:50:59 < upgrdman> Cracki, it can so MSAA but not very nicely. it'll work, but it's make my code more... robust ;) now i have to check for things that i took for granted
2020-05-08T09:51:06 < Cracki> PaulFertser, dongs, YES it's overpriced for the cost of design and making, NO it's not overpriced for the kinds of customers who need it
2020-05-08T09:51:25 < Cracki> ah the things we take for granted, such as correct floating point results :>

2020-05-08T12:09:23 < catphish> passive hub? how does that work?
2020-05-08T12:12:41 < jpa-> catphish: just passive coupling between ports so that all data coming in goes out of every port
2020-05-08T12:13:00 < jpa-> conceptually similar to just hooking all wires together, except avoiding the impedance mismatch etc.
2020-05-08T12:17:26 < catphish> but specifically how would you do that?
2020-05-08T12:17:51 < catphish> i've never seen such a thing
2020-05-08T12:18:21 < catphish> diodes maybe?
2020-05-08T12:18:25 < mawk> I think you used the wrong unit there strata: 01:26 <strata> i am thinking this will help for other plants too. peppers like to germinate in 75-80 degree soil temp
2020-05-08T12:18:51 < catphish> 75-80 degrees wow
2020-05-08T12:20:02 < Cracki> catphish, you might be right https://www.eeweb.com/circuit-projects/building-a-passive-ethernet-hub
2020-05-08T12:20:13 < catphish> i just found https://cdn.eeweb.com/articles/articles/the-setting-of-a-passive-ethernet-hub-1326382960.gif
2020-05-08T12:20:49 < catphish> ah same thing :)
2020-05-08T12:20:56 < Cracki> not sure what those diodes are good for except some fixed voltage drop
2020-05-08T12:22:28 < catphish> i don't understand this design at all
2020-05-08T12:24:19 < catphish> Cracki: actually i do understand it
2020-05-08T12:24:35 < catphish> it's a ring of TX-RX-TX-RX-TX-TX
2020-05-08T12:24:40 < Cracki> probably not far away from ethernet over coax
2020-05-08T12:24:42 < Cracki> ic
2020-05-08T12:24:56 < catphish> the tx voltage is high enough to pass through one diode only
2020-05-08T12:25:00 < Cracki> I'm not sure it can be a ring. it needs to be one medium
2020-05-08T12:25:13 < catphish> so no current flows from one TX line to another
2020-05-08T12:25:22 < catphish> only from TX to its 2 adjacent RX lines
2020-05-08T12:26:23 < catphish> so imagine if you have TX (1v) [DIODE] RX [DIODE] TX (0v)
2020-05-08T12:26:34 < catphish> no current flows from the first TX to the second
2020-05-08T12:26:50 < catphish> but some current can flow from the 1v TX to the RX
2020-05-08T12:27:12 < Cracki> eh just tie it all together
2020-05-08T12:27:53 < catphish> so each RX line sees a logical OR of its 2 neighbours (at significantly reduced power)
2020-05-08T12:28:10 < catphish> only works for maximum 3 hosts
2020-05-08T12:29:22 < Cracki> if it works like that, how is it supposed to carry information to non-neighbors
2020-05-08T12:29:24 < Cracki> this isn't token ring
2020-05-08T12:31:43 < catphish> non-neighbours?
2020-05-08T12:31:56 < catphish> it doesn't, it's a star of maximum 3 hosts
2020-05-08T12:32:10 < Cracki> right, abc
2020-05-08T12:32:30 < catphish> like, sitting round a table, everyone sits next to only 2 people
2020-05-08T12:35:48 < PaulFertser> But you can have logical OR with arbitrary number of diodes (if you have enough power)
2020-05-08T12:36:14 < PaulFertser> So each device's Rx can be connected to each device's Tx.
2020-05-08T12:36:35 < PaulFertser> No?
2020-05-08T12:36:36 < catphish> PaulFertser: actually you're right,
2020-05-08T12:36:48 < catphish> i don't know why they didn't draw it that way
2020-05-08T12:37:01 < catphish> oh, no
2020-05-08T12:37:46 < catphish> i think it won't work because it's AC
2020-05-08T12:38:12 < catphish> the TX line has to sink current too

2020-05-08T12:40:03 < PaulFertser> There certainly were some active ethernet hubs which were not switches.
2020-05-08T12:40:17 < catphish> of course
2020-05-08T12:41:30 < catphish> early ethernet used either a shared coax (one line for tx and rx) or cat5 with an active hub
2020-05-08T12:43:06 < PaulFertser> We were discussing modern high-speed shared medium options.
2020-05-08T12:43:33 < PaulFertser> btw, faster CAN is in the works, but it's still not that fas.t

2020-05-08T14:23:16 < strata> what is this datasheet.lcsc.com the one true authoritative source for datasheets?
2020-05-08T14:23:28 < dongs> nope, but its a source of chink datasheets
2020-05-08T14:27:33 < mrec> recently I tried to get a datasheet of an image sensor vendor... takes like 2 weeks... you ask a few chinese vendors you get it within 1 day and they don't care about NDAs I think they understand it as DAs (cutting the N in it)
2020-05-08T14:33:20 < mawk> dongs: TAMER is YOURMOM in french
2020-05-08T14:34:07 < mawk> which implicitely means "fuck your mom"

2020-05-08T14:49:36 < Ad0> lol the bootloader bug yesterday on my stm32g03 was hardware revision that halted everything if RX on UART2 was low...
2020-05-08T14:49:51 < Ad0> newer revision of the chip and the issue was solved
2020-05-08T14:50:36 < Ad0> I look in the source code for stm32flash and the dev table is like this: {0x460, "STM32G07xxx/08xxx"               , 0x20003000, 0x20009000, 0x08000000, 0x08020000,  1, p_2k  , 0x1FFF7800, 0x1FFF787F, 0x1FFF0000, 0x1FFF7000, 0},
2020-05-08T14:51:51 < Ad0> fields are ID, "name", SRAM-address-range, FLASH-address-range, PPS, PSize, Option-byte-addr-range,System-mem-addr-range,Flags
2020-05-08T14:52:41 < Ad0> how the heck do they find these numbers?
2020-05-08T14:53:02 < Ad0> I knopw some of it is in AN2606 but not everything
2020-05-08T15:03:15 < PaulFertser> Ad0: what numbers are you missing?
2020-05-08T15:03:34 < PaulFertser> The device datasheet should have them.
2020-05-08T15:03:55 < Ad0> I have stm32g03 right so I assume those addresses are added +1 to get 0x20009000 etc

2020-05-08T15:05:05 < Ad0> the address range I mean
2020-05-08T15:05:59 < Ad0> https://www.st.com/resource/en/datasheet/stm32g030c8.pdf - no 0x08000000 for instance
2020-05-08T15:06:35 < Ad0> but I can connect the stlink and read the pages and addresses and see where they end
2020-05-08T15:06:54 < PaulFertser> Ad0: family reference manual should also be handy, I think you'll find memory map there, and it'll be showing flash mapped to that address.
2020-05-08T15:07:05 < Ad0> right! thanks

2020-05-08T18:26:00 < englishman> it gives you a raw adc output without applying calibration. so instead of reading two registers for a 16 bit output you have to read 8 and do linear interpolation
2020-05-08T18:26:47 < englishman> it's also less precise and 1.5x price of silabs

2020-05-08T18:32:54 < englishman> because that interpolation turns into extrapolation outside of the calibrated range, i doubt the readings outside of the calibrated range

2020-05-08T22:03:44 < jadew> neat
2020-05-08T22:03:52 < jadew> what did you cut with it so far?
2020-05-08T22:03:54 < jadew> got pictures?
2020-05-08T22:03:58 < Steffanx> Nah, no lasering boddax

2020-05-08T22:04:21 < jadew> for lasers you need e good enclosure I guess
2020-05-08T22:04:29 < Steffanx> Just some basic things. Until something failed totally a few weeks ago and i decided to redo the electronics
2020-05-08T22:04:42 < boddax> eheh preparing the struffels with that
2020-05-08T22:04:43 < jadew> so you don't breathe in whatever gets released from the process

2020-05-08T22:57:33 < nn7> if I have a decoupling cap next to the STM and it's across the power and ground pins, one of them needs a via. Do I put the via on the chip side, on the capacitor side, or inbetween?
2020-05-08T22:57:48 < strata> i always assumed that if you're not already extremely well funded and are able to get a government to give you access to free energy by way of land purchase, then you're wasting your money.

2020-05-08T23:00:03 < zyp> it's a xc7a200t, you'd pay more to buy just the fpga than what those boards are selling for
2020-05-08T23:02:48 < zyp> qyx, so I've got kinda crazy ideas about stuff, I wanna make a backplane with a crosspoint switch, like 40x40, which will give me 40 lane-pairs to distribute across a number of slots
2020-05-08T23:03:09 < qyx> what for, to play with?
2020-05-08T23:03:12 < zyp> yes
2020-05-08T23:03:37 < zyp> basically I wanna be able to just plug stuff together and set up connections for whatever
2020-05-08T23:04:19 < zyp> e.g. I could have a x16 slot, stick a pcie switch card in that, giving me 16 lanes of pcie to distribute across the other slots
2020-05-08T23:04:34 < PaulFertser> zyp: have you checked that powerlink "canopen over ethernet" link? They even offer some VHDL code it seems.
2020-05-08T23:05:06 < zyp> while other lanes are running shit like usb3, sgmii, sata or whatever
2020-05-08T23:07:05 < zyp> so in practice you could also stick a nvme ssd in the m.2 carrier and run pcie to it
2020-05-08T23:08:06 < qyx> multimodularzyp
2020-05-08T23:08:16 < qyx> its gonna be power hungry
2020-05-08T23:08:29 < zyp> yes, I've been wondering what to do about power
2020-05-08T23:09:18 < qyx> I did insert a linux-wireless-lte-gprs-whatever thing into my sub-sub-rack
2020-05-08T23:09:33 < qyx> together with a battery managment board & charger
2020-05-08T23:09:40 < qyx> it dissipated about 1W
2020-05-08T23:09:47 < zyp> having a card feed into the 12V rail in the pcie socket doesn't seem reasonable anymore :)
2020-05-08T23:10:13 < qyx> and the thing was heating more than I liked
2020-05-08T23:11:04 < zyp> I think an easy solution would be stuffing an ATX PSU into the chassis
2020-05-08T23:11:30 < zyp> but I'd like to keep that modular too, USB PD would still be plenty for lower power combinations

2020-05-08T23:12:33 < zyp> so I'm thinking maybe I should make a dedicated power slot that's using a higher power connector instead of or in addition to a pcie socket
2020-05-08T23:18:35 < qyx> how much do you require? a single PCIe pin can supply 1.1A
2020-05-08T23:18:55 < qyx> 8A at 12V is enough what USB PD can supply
2020-05-08T23:19:04 < qyx> and 8 pins + some grounds is not that much
2020-05-08T23:19:15 < qyx> I am using 4 pins for power (5V 4A max)

2020-05-09T00:22:25 < PaulFertser> Another wild guess would be incorrect flash wait states for the configured frequency, but I would assume clock configuration is performed later than __libc_init_array
2020-05-09T00:25:10 < PaulFertser> Hm, no, it's after.
2020-05-09T00:26:33 < PaulFertser> But SystemInit is empty
2020-05-09T00:27:29 < PaulFertser> I see, HAL does clock config from main()
2020-05-09T00:30:04 < ColdKeyboard> So with the debug I get to the point "080038A4   PUSH           {R4-R6, LR}" and then next step lands in HardFault
2020-05-09T00:30:23 < PaulFertser> ColdKeyboard: before doing push check SP
2020-05-09T00:30:27 < karlp> what's the fault?
2020-05-09T00:31:16 < ColdKeyboard> R13(SP) is showing 2000 1800
2020-05-09T00:31:57 < PaulFertser> That's the correct and expected value...
2020-05-09T00:33:47 -!- bvernoux [~Ben@88.120.152.126] has quit [Quit: Leaving]
2020-05-09T00:34:15 < zyp> ColdKeyboard, that's with single instruction stepping?
2020-05-09T00:34:19 -!- smvoss_ is now known as smvoss
2020-05-09T00:34:43 < zyp> are you certain your chip is a stm32f070f6?
2020-05-09T00:35:14 < PaulFertser> bl SystemInit worked though
2020-05-09T00:35:23 < PaulFertser> Ah, it's link, not stack
2020-05-09T00:35:29 < PaulFertser> So nothing was using stack before that
2020-05-09T00:35:40 < zyp> yes, that's how ARM ABI works
2020-05-09T00:35:57 < PaulFertser> So there's an STM32 part which has less than 6 kiB RAM?
2020-05-09T00:36:17 < karlp> hrm, wb nucleo turne dup today, stuffed in my mailbox, yay no fees!  also contianed a note inside apologising for the delivery delay :)
2020-05-09T00:36:25 < zyp> stm32f030f4 has 4k :)
2020-05-09T00:36:32 < karlp> PaulFertser:there's some tiny ones, I had to reduce shit on the miniblink repo
2020-05-09T00:36:35 < karlp> yeah, that's it
2020-05-09T00:37:07 < karlp> the miniblink targets 8k flash, 2k ram so it runs on "all" stm32s 
2020-05-09T00:37:43 < zyp> errata sheet for f070 has nothing indicating using top of 6k shouldn't work
2020-05-09T00:38:29 < zyp> karlp, but to blink you need gpio and for gpio you need rcc and both of those differ in address from family to family
2020-05-09T00:40:41 < karlp> well, yeah, it's "libopencm3-miniblink" not "this blink file runs on everything"
2020-05-09T00:40:47 < karlp> but I have a single ld script for all stm32s
2020-05-09T00:41:03 < karlp> and that f030f4 required me to turn it down a bit.
2020-05-09T00:42:49 < ColdKeyboard> Is there an example project that is known to work for this MCU that I can compile and see if it works_
2020-05-09T00:43:02 < ColdKeyboard> I'm not sure why this build is failing
2020-05-09T00:43:23 < karlp> sure, try this mini blink: https://github.com/libopencm3/libopencm3-miniblink/
2020-05-09T00:44:07 < PaulFertser> ColdKeyboard: so what your part is exactly, can you read markings on the chip?
2020-05-09T00:44:14 < zyp> ColdKeyboard, are you using a gui debugger or gdb?
2020-05-09T00:44:15 < karlp> that repo's purpose is "is my toolchain environment functional"
2020-05-09T00:44:47 < zyp> karlp, the .elf looks correct though
2020-05-09T00:44:51  * karlp shrugs
2020-05-09T00:46:02 < zyp> ColdKeyboard, if you've got a gdb command line available, can you do a «x/wx 0x40015800»?
2020-05-09T00:47:40 < zyp> that is IDCODE, it's supposed to read 0x10006445 in your case
2020-05-09T00:52:04 < ColdKeyboard> zyp I'm using GUI debugger
2020-05-09T00:52:23 < ColdKeyboard> It's the only STM32F070 in SOP20 package :)
2020-05-09T00:52:29 < ColdKeyboard> Let me try running that command over gdb
2020-05-09T00:53:07 < zyp> x/wx is shorthand for examine word hex, i.e. read out a 32-bit value and display it as hexadecimal
2020-05-09T00:53:29 < zyp> you've probably got a gui box to do the same somewhere
2020-05-09T00:55:48 < ColdKeyboard> This is address in memory?
2020-05-09T00:56:05 < zyp> it's a memory mapped register
2020-05-09T00:56:44 < ColdKeyboard> https://i.imgur.com/4GyOijb.png
2020-05-09T00:57:09 < ColdKeyboard> Do I have the wrong thing?
2020-05-09T00:57:15 < zyp> everything is mapped into the same memory space, flash at 0x08000000, ram at 0x20000000, various memory mapped registers starting at 0x40000000
2020-05-09T00:57:34 < zyp> 0x10006444
2020-05-09T00:58:03 < zyp> according to the datasheet you don't have a stm32f070, you've got a stm32f030 :)
2020-05-09T00:58:10 < ColdKeyboard> Reading it backwards I would see 10006444
2020-05-09T00:58:15 < ColdKeyboard> :(((
2020-05-09T00:58:22 < ColdKeyboard> God dammit
2020-05-09T00:58:30  * ColdKeyboard sigh
2020-05-09T00:58:42 < zyp> well, it explains the problem, you're trying to push a value at end of 6k, but you've only got 4k of ram
2020-05-09T00:59:13 < ColdKeyboard> Mislabeled the entire bin...
2020-05-09T00:59:20 < ColdKeyboard> Well being a moron is always fun :)
2020-05-09T00:59:29 < ColdKeyboard> Thank a lot for all the help zyp!
2020-05-09T00:59:50 < zyp> did you buy «upgraded» chips from china or something?
2020-05-09T00:59:53 < zyp> how did this happen?
2020-05-09T01:01:22 < ColdKeyboard> I'm looking for a really cheap MCU with USB and PWM so I remembered that I have STM32F070 in SOP20 package that I sodlered to one of those breakout boards. Now I did this yeeears ago and for some reason I labels the board wrong so I was convinced it's 070 and not 030...
2020-05-09T01:01:34 < ColdKeyboard> Didn't even know I have 030 xD
2020-05-09T01:01:49 < zyp> ah, so you didn't look at the chip itself?
2020-05-09T01:02:39 < ColdKeyboard> It's totally ilegible from all the soldering, flux, scratches etc
2020-05-09T01:02:50 < zyp> haha, fair point
2020-05-09T01:03:00 < ColdKeyboard> Lesson learned :)

2020-05-09T01:03:42 < ColdKeyboard> Irony is that I have nucleo board for STM32072 but I wanted to do it directly on STM32F070 so I don't have to modify FW too much when I get the boards
2020-05-09T01:03:46 < zyp> so you need a cheap MCU with USB? how many do you need?

2020-05-09T01:04:44 < ColdKeyboard> I made a project for myself and now people are asking if I can build board and send it to them...
2020-05-09T01:05:26 < ColdKeyboard> When I made mine, I didn't care that I'm using $6 MCU + $3 DAC etc. but now if people are going to be building it, I want to dial the BoM down as much as possible
2020-05-09T01:05:52 < zyp> I managed to buy 100 pieces of stm32l052 in the wrong package a while ago (bought 64pin, was supposed to be 48pin), so if you'd be interested, I want to get rid of them
2020-05-09T01:06:58 < Thorn> can you please buy a tray of stm32mp1 in the wrong package too? lol
2020-05-09T01:07:08 < zyp> haha
2020-05-09T01:07:13 < ColdKeyboard> That's a nice offer. I'll think about it. Once really nice thing about 070 is that it's in SOP20 package so most people can solder it super easy
2020-05-09T01:08:10 < ColdKeyboard> I love when people give PCB design and open-source open-hardware everything but most of the components are BGA or CSP... like I appreciate that you are sharing but realisticly who is going to build this :)
2020-05-09T01:08:28 < zyp> I don't think qfp64 would be any harder than sop20 really
2020-05-09T01:09:09 < zyp> 0.5 vs 0.65mm pitch, but still, those are both dense enough that you'd do flood and suck or drag soldering if assembling by hand
2020-05-09T01:09:32 < zyp> it'd be a different matter if it were qfn :)

2020-05-09T01:10:31 < ColdKeyboard> Can you even solder it with just the soldering iron?
2020-05-09T01:10:40 < ColdKeyboard> I usually use hot air gun for those
2020-05-09T01:11:22 < Thorn> the only fun package is bga. GB and GHz come only in bga
2020-05-09T01:12:22 < zyp> qfp too
2020-05-09T01:13:59 < zyp> ColdKeyboard, anyway, if you want the l052, you can have them for $1/ea plus shipping
2020-05-09T01:15:34 < zyp> hmm
2020-05-09T01:16:12 < zyp> I see f070 is still cheaper, like $0.68 @100 at lcsc

2020-05-09T02:11:06 < Thorn> how much slower a 1-chip 16-bit ddr3 memory would be compared to 2-chip 16+16-bit? same clock freq / timings
2020-05-09T02:12:46 < zyp> 32-bit wide, or two ranks of 16-bit?
2020-05-09T02:14:02 < zyp> width wise, I'd expect throughput to scale proportionally with number of bits
2020-05-09T02:14:32 < zyp> since you'd be controlling both chips in parallel, just doubling number of bits per actual transfer
2020-05-09T02:15:12 < zyp> i.e. equal time spent on management and latency and stuff, just twice as much data
2020-05-09T02:16:10 < zyp> with two ranks instead, you've got the data lanes in parallel, just separate chip selects
2020-05-09T02:18:00 < zyp> in which case I don't think speed would increase much, but if my understanding is correct you could have twice the number of banks open at a time, which might give slight latency improvements

2020-05-09T03:28:50 < zyp> and the main reason it took so long was that I didn't want the ISP that was already established in the area but the ISP that was about to extend into the area
2020-05-09T03:29:39 < zyp> karlp, by the way, what countertops did you end up with?
2020-05-09T03:30:26 < karlp> some HPL ones,
2020-05-09T03:30:39 < zyp> ah
2020-05-09T03:30:54 < karlp> "made" locally by a company here, not sure which euro vendor they used in the end
2020-05-09T03:31:05 < karlp> that's tbeen the most hassle actually
2020-05-09T03:31:34 < karlp> our builder wasn't used to it, and it's much harder than what he's used to working with, and he managed to scratch it up with a jigsaw and blah
2020-05-09T03:31:52 < zyp> heh
2020-05-09T03:31:53 < karlp> sooo we're getting another one, and this time, the _shop_ is routing out the sink and cooktop instead of the builder
2020-05-09T03:32:07 < karlp> so, oven and bbq and takeaway for the first week...
2020-05-09T03:32:16 < zyp> ah
2020-05-09T03:32:34 < karlp> the whole renos had been going really super smoothly though, so can't be too upset :)
2020-05-09T03:33:48 < zyp> I got mine with the sink already mounted, flush with the surface, but they didn't wanna route the cooktop for me because the hole would be too close to the corner
2020-05-09T03:34:01 < zyp> something about risk of transport damage
2020-05-09T03:38:30 < karlp> yeah, it'll be mor efragile once they've routed it, and it was a absolute pain getting it up and in to the new place, because it's 3.9m long
2020-05-09T03:39:08 < karlp> we wallpapered one wall,
2020-05-09T03:39:19 < karlp> looks really nice, paid 25k for the dude to do it.
2020-05-09T03:39:38 < karlp> took ~2-3 hours.  called another guy, got quoted 150k and 2 days
2020-05-09T03:39:50 < zyp> ah, mine's L-shaped, IIRC the parts are 3m-ish and 2m-ish
2020-05-09T03:40:50 < karlp> yeah, ours too, but the long one is 3.9
2020-05-09T03:41:03 < karlp> the short one is .. I don'ty remember, but shorter is shorter
2020-05-09T03:41:59 < karlp> in https://nc.beeroclock.net/s/nKemfX4Rz9DJ7n3#//32cd6a928da934c0b7dd84fcf84aa8f7-large.jpg
2020-05-09T03:42:05 < zyp> not really a problem getting anything up and in here though, the outdoor stairs to the balcony behind the house are straight, and then just around the house and in
2020-05-09T03:42:21 < karlp> we ripped out the right hand side, rebuilt it at the heigh matching the rest
2020-05-09T03:42:37 < karlp> and lengthend it for just a "normal" fridge width, instead of the fat on there.
2020-05-09T03:43:00 < karlp> suspect a dwarf lived there in the past.
2020-05-09T03:43:03 < zyp> ah, nice
2020-05-09T03:43:07 < zyp> yeah, was about to ask
2020-05-09T03:43:10 < karlp> cooktop was super low, and toilet was low too.
2020-05-09T03:43:18 < zyp> weird combination of counters
2020-05-09T03:43:18 < karlp> both now raised up to more normal heights
2020-05-09T03:43:46 < zyp> you didn't consider doing side by side fridge and freezer?
2020-05-09T03:45:04 < karlp> https://nc.beeroclock.net/s/GtisBZMjsqq2dc4 here's the doorway into that kitchen now, from the loungroom, featuring my wife
2020-05-09T03:45:23 < karlp> zyp: we did briefly, but decied we were quite happy with the separate freezer
2020-05-09T03:45:42 < karlp> we have a full height fridge now, and a half  heigh freezer in another room
2020-05-09T03:45:46 < karlp> expect to keep that setup
2020-05-09T03:45:48 < zyp> ah
2020-05-09T03:46:13 < zyp> I mean, I have a full height separate freezer, I just have it next to the fridge :)
2020-05-09T03:47:00 < karlp> kitchen looks more like this now https://nc.beeroclock.net/s/nKemfX4Rz9DJ7n3#//32cd6a928da934c0b7dd84fcf84aa8f7-large.jpg
2020-05-09T03:47:15 < karlp> well, you have a full height freezer, but not as wide right?
2020-05-09T03:47:25 < karlp> the existing space there was a 1.5 wide style
2020-05-09T03:47:32 < karlp> and really, fuck that style, I don't get it.
2020-05-09T03:47:47 < zyp> both freezer and fridge are full 60 by 180

2020-05-09T03:47:58 < karlp> oh, you have full on double double
2020-05-09T03:48:06 < karlp> yeah, the space there was only ~90 wide
2020-05-09T03:48:09 < zyp> https://bin.jvnv.net/file/AYNj3.jpg <- before installation
2020-05-09T03:48:22 < karlp> yeah, that would be ok,

2020-05-09T03:48:59 < karlp> huh, I don't remember that one, did you really do double ovens?

2020-05-09T03:52:35 < karlp> hrm, quite a bit more htan I'd like to spend right now, but a combination I wasn't aware of. looks nice
2020-05-09T03:52:51 < karlp> better than the double wide ovens at least
2020-05-09T03:53:34 < zyp> having two ovens wasn't really the point, but I wanted to have both an integrated microwave and an integrated oven
2020-05-09T03:54:58 < zyp> I think I've used the microwave as an oven once so far, and that was more to try it out rather than a real need
2020-05-09T03:56:16 < zyp> and regarding the price, they were on the «I'd like to get those at some point in the future»-list for me, because I had a perfectly good standalone combo microwave before I moved
2020-05-09T03:57:31 < zyp> and then suddenly ikea announced 20% off on all kitchen appliances
2020-05-09T03:58:16 < zyp> was planning to make do with the old free standing fridge for a while as well
2020-05-09T03:58:18 < karlp> I looked a lot at a combo mcirowave recently, our old one packed it in, but I just couldn't really think of it, and just got a plain old microwave *shrugs*
2020-05-09T03:58:47 < karlp> anyway, late. packing saturday, kids go for a sleep over, then move
2020-05-09T03:58:56 < zyp> enjoy :)

2020-05-09T10:03:51 < catphish> can someone tell me how / why "extern uint8_t variable[]" and "extern uint8_t * variable" differ?
2020-05-09T10:04:59 < catphish> oh, actually, i just realised exactly how they differ, never mind
2020-05-09T10:06:58 < catphish> i keep confusing the two, but i just realised why they behave totally differently :)
2020-05-09T10:08:11 < PaulFertser> catphish: hm, my first thought would be that they do not differ until you try to change "variable" somehow.
2020-05-09T10:09:18 < catphish> the former says "this memory location contains the data of an array" the latter says "this memory location contains the address of one or more items", they are in fact totally differnt things
2020-05-09T10:09:56 < PaulFertser> catphish: isn't an array the same as "one or more items"?
2020-05-09T10:12:59 < PaulFertser> So the first says data starts right there, substitute data address where I use variable. And the second says substitute the pointer to data where I say variable.
2020-05-09T10:13:13 < PaulFertser> Hm, so it matters for external linkage, OK, I see.
2020-05-09T10:13:26 < catphish> in both cases, "variable" points to the raw data, the problem is that "uint8_t * variable" should NOT point to data, is should point to an address
2020-05-09T10:14:08 < catphish> right, what you said
2020-05-09T10:15:06 < Cracki> diff is result of sizeof()
2020-05-09T10:15:18 < catphish> when you try to use it, the second attempts to get an address and follow it, where the first does the correct thing and goes straight to the data
2020-05-09T10:15:24 < Cracki> wat
2020-05-09T10:15:48 < Cracki> both are externs so their identifiers used blank behave like pointers
2020-05-09T10:16:33 < catphish> they behave totally differently
2020-05-09T10:16:34 < Cracki> sizeof(ptr) is size of pointer, sizeof(array) is length of array in bytes... but I guess with a [] it can't tell
2020-05-09T10:16:44 < Cracki> in what situation do they behave differently
2020-05-09T10:16:44 < PaulFertser> That's what I thought but apparently not for externs. https://stackoverflow.com/questions/43610076/extern-pointer-to-variable-vs-array use example from here to see for yourself Cracki 
2020-05-09T10:17:32 < Cracki> eh, people breaking their brain with indirection
2020-05-09T10:17:42 < Cracki> it's not that weird
2020-05-09T10:17:55 < catphish> i don't know why i was being so dumb, the second one the second one obviously expects the external data to be a pointer
2020-05-09T10:18:06 < catphish> where the first one expects the external data to be data
2020-05-09T10:18:22 < PaulFertser> It's jsut that we're so used to the idea "pointer and array is the same thing essentially" that tricks us
2020-05-09T10:18:48 < catphish> yeah, i think that's why i was confused, i'm used to using them the same way
2020-05-09T10:19:02 < Cracki> &array == array. it's a weird special case of C
2020-05-09T10:19:06 < Cracki> &ptr != ptr in general
2020-05-09T10:19:34 < Cracki> but still, *array is like *ptr
2020-05-09T10:19:44 < Cracki> *array == array[0], *ptr == ptr[0]
2020-05-09T10:19:48 < PaulFertser> Thing is, you can use "array" as an argument to a function that expects pointer.
2020-05-09T10:19:52 < Cracki> sure
2020-05-09T10:20:14 < Cracki> why are we talking about this again?
2020-05-09T10:20:26 < PaulFertser> Because in the case you do the same with extern it stops working :)
2020-05-09T10:20:32 < Cracki> orly
2020-05-09T10:20:34 < Cracki> how
2020-05-09T10:20:47 < Cracki> I don't quite follow, you're too vague for my attention span
2020-05-09T10:21:09 < Cracki> I'm not disagreeing, I don't understand what you mean in the first place
2020-05-09T10:21:32 < PaulFertser> Translation unit that has extern * declaration treats the address as a variable holding a pointer. While in fact the variable is array data itself.
2020-05-09T10:21:47 < Cracki> wat
2020-05-09T10:22:21 < Cracki> more precise please. why are you talking about arrays when you say "extern *"
2020-05-09T10:23:12 < PaulFertser> I thought that I can declare a global visibility array and then link to it with extern *.
2020-05-09T10:23:22 < PaulFertser> (by using the same name)
2020-05-09T10:23:36 < PaulFertser> Because "array and pointer are equivalent".
2020-05-09T10:23:39 < catphish> that's what i just tried to do :)
2020-05-09T10:23:42 < Cracki> obviously a pointer actually has some space in memory where the contents of it exist (the address it stores). an array doesn't have that.
2020-05-09T10:23:51 < Cracki> wat you want to mix things?
2020-05-09T10:24:00 < catphish> Cracki: right, *that* was my confusion
2020-05-09T10:24:41 < Cracki> int number; int *ptr; int array[10];
2020-05-09T10:24:51 < Cracki> number has 4 or 8 bytes in ram that hold its value
2020-05-09T10:25:02 < Cracki> ptr has 4 or 8 bytes in memory that hold its value, which is an address to something
2020-05-09T10:25:04 < PaulFertser> But in the same translation unit you can use array whenever pointer is required and it just works.
2020-05-09T10:25:09 < PaulFertser> That's why it's confusing.
2020-05-09T10:25:13 < Cracki> you can ask for &number and &ptr and get the addresses to those locations
2020-05-09T10:25:18 < catphish> to clarify, i tried to do this in one file: int data[10] and this in another file: extern int * data;
2020-05-09T10:25:35 < catphish> and thought the pointer would somehow be populated with the address of the array
2020-05-09T10:25:42 < catphish> but that's nonsense
2020-05-09T10:25:48 < Cracki> array is ten ints somewhere in memory. "array" is an address/ptr to the first element, but &array is the same
2020-05-09T10:26:08 < Cracki> I would hope that the linker or compiler already complains
2020-05-09T10:26:34 < catphish> my compiler didn't give one solitary fuck, and just tried to dereference the data in my array :)
2020-05-09T10:26:37 < Cracki> correct. for an array there is nowhere in memory that holds the address to those elements
2020-05-09T10:26:50 < Cracki> do you include the header in the source file?
2020-05-09T10:27:01 < catphish> what header?
2020-05-09T10:27:04 < Cracki> then you'd have, after preprocessing, an extern int* line above an int [] line
2020-05-09T10:27:19 < Cracki> header is the thing where extern something is put into
2020-05-09T10:27:44 < Cracki> it is customary to call header foo.h and source file foo.c, and to #include "foo.h" in foo.c
2020-05-09T10:28:03 < PaulFertser> catphish: you compiler didn't complain because you're supposed to include a header file with "extern" in all translation units using the variable, including the one declaring it.
2020-05-09T10:28:12 < Cracki> names are sound and smoke but you get the idea
2020-05-09T10:28:14 < PaulFertser> Yeah
2020-05-09T10:28:34 < catphish> PaulFertser: yeah i just realised thats's what Cracki meant, i will start doing so
2020-05-09T10:28:34 < Cracki> you can of course proclaim "extern somthing" anywhere
2020-05-09T10:28:54 < catphish> i end to only include header files when something is missing
2020-05-09T10:29:00 < Cracki> but the proper thing is to put that in _one_ header, and include that header anywhere you need it, which is also the source file where that variable is actually declared
2020-05-09T10:29:03 < catphish> *i tend
2020-05-09T10:29:35 < Cracki> that way the compiler has a chance to check what's in the header against what's in the source file
2020-05-09T10:29:41 < catphish> actually i could put the extern only in the header of the c file that declares it right?
2020-05-09T10:30:01 < catphish> no need to litter externs elsewhere
2020-05-09T10:30:17 < Cracki> also it acts as forward declarations, i.e. you define functions foo() and bar() and foo can call bar() already even though it comes after, because the header has the signature and the header was included first in the source file
2020-05-09T10:30:25 < Cracki> correct
2020-05-09T10:30:41 < PaulFertser> C is sick.
2020-05-09T10:30:44 < catphish> yeah, i do this for all my functions as you describe
2020-05-09T10:30:44 < Cracki> some variable goes in foo.c, its extern declaration goes in foo.h, and everything includes foo.h
2020-05-09T10:30:54 < catphish> never occurred to me to do it for global vatiables
2020-05-09T10:31:45 < catphish> thanks
2020-05-09T10:31:52 < Cracki> functions don't need to be declared extern, that's implicit
2020-05-09T10:32:10 < Cracki> (I never thought about it, just stuck to the pattern I learned)
2020-05-09T10:33:19 < catphish> i usually write a c file, then copy all the function definitions into an identically named .h file
2020-05-09T10:33:29 < Cracki> ye
2020-05-09T10:33:34 < catphish> just never occurred to me to do the same for any global variables
2020-05-09T10:33:43 < catphish> i will start doing so, though i use them very rarely
2020-05-09T10:37:41 < jpa-> i usually write .h file and copy them to .c file
2020-05-09T10:39:30 < Cracki> this truestudio/cubeide bullshit doesn't seem to help with prototype/function signatures, or does it?
2020-05-09T10:39:55 < Cracki> I used to work with eclipse CDT on a C code base and I don't remember that it was as painful as truestudio/cubeide
2020-05-09T10:40:26 < Cracki> don't see anything to "create function" from prototype, or to "create prototype" from function
2020-05-09T10:40:47 < Cracki> nor does it help move shit along when I move functions between modules
2020-05-09T10:41:34 < PaulFertser> The "funniest" related bug I had is when some global variable for whatever odd reason wasn't declared static and then in another unrelated file I accidentally named another variable the same and have forgotten static too. And the linker merged them silently.
2020-05-09T10:42:00 < jpa-> i've done that too
2020-05-09T10:42:30 < Cracki> hell I hope that never happens to me. I never thought about that.
2020-05-09T10:42:49 < Cracki> only bugs related to variables I had so far were when it wasn't volatile but should have been
2020-05-09T10:43:06 < PaulFertser> C is very fragile by default. Static and const should have been always implied...
2020-05-09T10:43:29 < jpa-> if you use -fno-common, ld should warn about that though
2020-05-09T10:46:05 < PaulFertser> -Wl,--warn-common
2020-05-09T10:46:46 < PaulFertser> And --fatal-warnings
2020-05-09T10:48:32 < jpa-> test.c:34: Warning: duplicate symbol 'foo'. This warning is fatal. You will die now.
2020-05-09T10:51:16 < PaulFertser> By default?
2020-05-09T10:52:07 < PaulFertser> It used to be not.

2020-05-09T11:07:54 < zyp> no, I don't think you'd die by default from making a duplicate symbol
2020-05-09T11:15:56 < PaulFertser> zyp: regarding that powerlink, I thought it was related to our discussion of fast-speed protocols. And I've seen them offering some hubs with fixed propogation delay.
2020-05-09T11:29:34 -!- Streaker is now known as offtopic
2020-05-09T11:46:28 < zyp> well, powerlink is just plain 100base-t half duplex, it's based around a poll/response pattern where a master is polling each node when it's their turn to speak
2020-05-09T11:47:29 < zyp> which means that throughput is latency limited, and therefore simple hubs/repeaters are used to keep latency down
2020-05-09T11:49:37 < zyp> the advantage of powerlink is that you don't need special MACs
2020-05-09T11:49:55 < zyp> otherwise, ethercat is apparently also canopen over ethernet
2020-05-09T11:51:06 < PaulFertser> Hm, they say it's essentially CANOpen over Ethernet. And in CANOpen each node can send a PDO at any moment.
2020-05-09T11:51:55 < PaulFertser> So if it's CANOpen without PDO (just SDO) then it's not so cool.
2020-05-09T11:52:36 < zyp> is that not the other way around? I haven't used canopen itself
2020-05-09T11:53:33 < zyp> in powerlink, PDO is sent at a fixed interval, SDO is sent during async phase
2020-05-09T11:54:12 < PaulFertser> When a node is just turned on it's waiting for master command to switch states. But once in "operational" it's sending unsolicited PDOs and watchdog (I do not remember how they call it) messages
2020-05-09T11:54:31 < zyp> https://www.ethernet-powerlink.org/fileadmin/_processed_/7/1/csm_002_1b_e_081128_cycle_RGB_acd2f91a74.jpg <- a powerlink cycle looks like this
2020-05-09T11:54:48 < zyp> PDOs are sent in PReq and PRes packets
2020-05-09T11:54:55 < PaulFertser> In normal canopen PDOs can be both periodic and aperiodic.
2020-05-09T11:55:00 < PaulFertser> iirc
2020-05-09T11:55:19 < PaulFertser> Hm, master sends SYNC and all slaves send their PDOs.
2020-05-09T11:56:40 < PaulFertser> But I am almost sure SDOs are all solicited and essentially unicast. In regular canopen.
2020-05-09T11:57:11 < PaulFertser> I guess powerlink is different enough then.

2020-05-09T12:18:12 < Thorn> I found pin package length spreadsheets for stm32mp1. according to them, address trace lengths inside the package (LFBGA324) vary from 2.73mm to 5.95mm. does this look realistic?
2020-05-09T12:20:06 < jpa-> how big is the package?
2020-05-09T12:21:34 < Thorn> 16x16mm
2020-05-09T12:25:24 < Thorn> actually that was for a 12x12mm 0.5mm bga. for 16x16 0.8mm, the range is 4.06...7.8mm
2020-05-09T12:31:54 < jpa-> sounds longish but possible
2020-05-09T12:34:18 < Thorn> ddr3 chips apparenlty have everything equalized in the package
2020-05-09T12:41:42 < Thorn> maximum length variation within a single data lane seems to be slightly over 1.5mm
2020-05-09T12:48:19 < zyp> doesn't sound all that unreasonable, I guess it might be routed around on the interposer a bit
2020-05-09T12:48:37 < zyp> hmm, probably not
2020-05-09T12:49:27 < zyp> but still, if the die is in the center and the signals are available on the outer balls, the distance doesn't sound unreasonable
2020-05-09T12:50:16 < Thorn> they're all on one side of the package
2020-05-09T12:50:55 < Thorn> for once ST has made an effort to make a convenient pinout
2020-05-09T12:51:15 < zyp> hmm, pin package length in altium came in AD16, my license is for AD15
2020-05-09T12:51:16 < zyp> aww
2020-05-09T12:52:17 < Thorn> altium is another story. afaik it was measured in mm/mils before 20 and in 20 it's now in ps
2020-05-09T12:53:01 < zyp> heh
2020-05-09T12:53:06 < Thorn> how am I supposed to convert it to ps, I don't know the epsilon of their interposer and stuff
2020-05-09T12:53:29 < zyp> well, neither does altium
2020-05-09T12:53:37 < Thorn> oh and I haven't found IBIS models for mp1
2020-05-09T12:53:44 < Thorn> how do I hyperlynx it
2020-05-09T12:56:01 < Thorn> oh found them finally 
2020-05-09T13:12:17 < Cracki> german lessons, today: "macht Platz da" https://pr0gramm.com/top/zeckenk%C3%A4rcher/2024253
2020-05-09T13:16:50 < zyp> what are good options for blind mate connectors that can also be used for wire to board?
2020-05-09T13:18:48 < zyp> molex mini-fit bmi looks like the cable plugs would also fit the bmi headers, but they don't have a 90 degree angle option of the bmi plugs
2020-05-09T13:21:18 < zyp> micro-fit on the other hand has the right angle pcb plug, but the bmi header has a shroud that would conflict with the retention clip on the cable plug
2020-05-09T13:22:59 < boddax> finally take a bath

2020-05-09T15:30:36 < zyp> ah
2020-05-09T15:30:46 < zyp> no, I actually don't
2020-05-09T15:31:10 < kakimir> what
2020-05-09T15:31:50 < zyp> between a reflow oven and a normal soldering iron, I haven't found much need for hot air
2020-05-09T15:32:23 < zyp> and I have a normal heat gun that could do in a pinch
2020-05-09T15:32:30 < kakimir> what
2020-05-09T15:32:39 < zyp> what what?
2020-05-09T15:32:43  * antto haz a $5 iron that plugz in teh wall
2020-05-09T15:32:46 < kakimir> what!
2020-05-09T15:33:16 < antto> thurrdy wattz
2020-05-09T15:33:19 < zyp> I mean, I'd rather invest in a better solder iron before anything else
2020-05-09T15:33:20 < antto> wat
2020-05-09T15:33:35 < BrainDamage> hot coal iron
2020-05-09T15:34:20 < zyp> https://www.jbctools.com/nase-nano-rework-product-929.html <- these things are great, this would be on the top of the list for me if I were putting money into soldering gear
2020-05-09T15:34:52 < antto> o_O
2020-05-09T15:35:19 < kakimir> zyp yes
2020-05-09T15:35:28 < kakimir> 1keur?
2020-05-09T15:35:39 < PaulFertser> It's pure magic. Pumping all that energy through tiny tip.
2020-05-09T15:36:05 < kakimir> if I had 1keur laying around
2020-05-09T15:36:08 < kakimir> I would get one
2020-05-09T15:36:14 < kakimir> without second guess
2020-05-09T15:36:15  * antto crushes two atomz together
2020-05-09T15:36:25 < PaulFertser> And super-handy changing of the tips too.
2020-05-09T15:37:52 < zyp> have you used one?
2020-05-09T15:38:26 < kakimir> I have seen one being used
2020-05-09T15:38:29 < zyp> your assessment is spot on, pure fucking magic
2020-05-09T15:38:37 < kakimir> 0 effort use
2020-05-09T15:39:07 < zyp> tools are only 14W, but it feels more powerful than my 80W weller because it gets all the power going where it's supposed to
2020-05-09T15:39:13 < PaulFertser> I was given an opportunity to play with one for 5 minutes. To heat a GND plane with it, to watch the power graphs.
2020-05-09T15:40:28 < zyp> I'm a bit tempted to get the handpiece and see if I can hack up a supply for it, like people have done for the other JBCs

2020-05-09T15:42:50 < strata> to me, a professional is someone who has spent at least 1000 hours doing something.
2020-05-09T15:43:17 < antto> my colegue is a professional sh*tter
2020-05-09T15:44:19 < zyp> to me, a professional is somebody doing something for a living
2020-05-09T15:44:28 < zyp> i.e. as a profession
2020-05-09T15:44:59 < PaulFertser> zyp: of course that's unscientific but when I see a professional at work it reminds me of a dancer, athlet or probably a skilled juggler, when all the moves are smooth, precise and connected.
2020-05-09T15:45:04 < antto> i'm a comput0r click0r and butten press0r
2020-05-09T15:45:35 < strata> pilots are one example of a profession where they clock time in different airplanes. hours of flight time. anyone with 1000 hours i consider professional and won't kill me.
2020-05-09T15:45:56 < strata> i like to apply that principle to all other fields. if you spent 1000 hours soldering, you're a professional.
2020-05-09T15:46:00 < antto> wut if he drunk
2020-05-09T15:46:14 < antto> how about 999 hours?
2020-05-09T15:46:18 < strata> if he drunk, i don't think he would make it to 1000 hours
2020-05-09T15:46:26 < zyp> strata, the problem with that is that I don't log soldering hours
2020-05-09T15:46:44 < antto> i have been soldering "wrong" for a long time btw
2020-05-09T15:46:56 < antto> then i watched some videos about flux..
2020-05-09T15:46:59 < Thorn> should i log datashit reading hours
2020-05-09T15:47:04 < kakimir> whatever works
2020-05-09T15:47:13 < strata> there is no "wrong" soldering if your joints are not defective
2020-05-09T15:47:18 < kakimir> if it works it ain't dumb
2020-05-09T15:47:32 < PaulFertser> It's dumb if you spare much more effort than necessary.
2020-05-09T15:47:40 < PaulFertser> (to get the same result)
2020-05-09T15:47:46 < antto> strata there is "wrong" when it clearly wastes more time and consumatives
2020-05-09T15:48:29 < antto> you can probably also get a nice looking joint using a torch
2020-05-09T15:48:37 < antto> or if you burn the whole house in a specific way
2020-05-09T15:48:42 < zyp> I feel I get far just with plain rosin core solder
2020-05-09T15:48:44 < antto> but that's wrong ;P~
2020-05-09T15:48:48 < Thorn> even cheaper 256Mx16 ddr3 https://lcsc.com/product-detail/SDRAM_Nanya-Tech-NT5CC256M16ER-EK_C428584.html
2020-05-09T15:48:53 < zyp> I've got a flux pen too, but I rarely find a need for that
2020-05-09T15:48:58 < PaulFertser> zyp: I do not think I was ever paid for soldering anything, at least can't remember any event like that atm. I'm a software developer.
2020-05-09T15:49:12 < antto> zyp yeah, rosin-core plus additional rosin-based flux that i brewed at home
2020-05-09T15:49:21 < strata> i like 1000 hours because at 1000 hours, most people are going to have learned to do things "right"
2020-05-09T15:49:22 < antto> thicc flux
2020-05-09T15:49:37 < strata> only crazy people would still be doing shit "wrong" at 1000 hours and beyond
2020-05-09T15:50:14 < antto> strata i don't agree ;P~
2020-05-09T15:50:21 < zyp> Thorn, nice
2020-05-09T15:50:31 < zyp> are you going for one or two?
2020-05-09T15:50:42 < PaulFertser> I think one of my students gave me a new portable HDD as a gift for helping fixing some hardware, but I can't remember the details, likely it involved some minor soldering job.
2020-05-09T15:50:43 < strata> i do not count getting paid to do a thing as "professional"
2020-05-09T15:51:10 < antto> i'm not saying that i agree with that either
2020-05-09T15:51:27 < antto> i don't know wut "pro" means, it's silly
2020-05-09T15:51:28 < strata> at least not at first
2020-05-09T15:51:38 < Thorn> zyp I'm looking at their sample layout, 354 bga 0.8mm + one ddr3 chip (96 balls 0.8mm), 4 layers(!)
2020-05-09T15:51:44 < strata> if they're doing it for a job - 1 year and then they're pro.
2020-05-09T15:51:46 < antto> when i see products with "PRO" in their name - i skip usually ;P~
2020-05-09T15:51:51 < Thorn> maybe I should adapt that and make a breakout first lol
2020-05-09T15:52:07 < zyp> PaulFertser, I'm also primarily a software developer, but I do embedded software
2020-05-09T15:52:09 < strata> if they're software developers, 10 years and then they're pro.
2020-05-09T15:52:13 < Thorn> strata what about all the string theorists
2020-05-09T15:52:34 < strata> especially if front end devs. then maybe 15-20 years until i consider them pro
2020-05-09T15:53:15 < strata> embedded devs? 6 months since i think most embedded devs already surpassed 1000 hours before ever getting a job
2020-05-09T15:53:44 < Cracki> ^
2020-05-09T15:53:48 < strata> unless they're in china
2020-05-09T15:54:10 < Cracki> 1kh is half a year of full time work
2020-05-09T15:54:11  * antto doesn't even know how many work days 1000 hours is
2020-05-09T15:54:21 < PaulFertser> I remember I once went to another student's place and I was teaching him soldering for few hours, in the end he assembled an ad-hoc AVR ISP programmer on a PCB breadboard.
2020-05-09T15:54:40 < Cracki> 25 weeks of 40 hours, adjust to taste
2020-05-09T15:54:55 < antto> i been teeching the new employees at my job how to solder ;P~
2020-05-09T15:54:55 < strata> Cracki: correct. for embedded devs, they can become "pro" at 6 months.
2020-05-09T15:55:03 < zyp> Thorn, well, yeah, 4L sounds feasible enough
2020-05-09T15:55:27 < Cracki> good tools are invaluable. you can't learn with shit tools. it's the same with soldering irons and flux (people never learn that you need lots of flux for rework), for IDEs/editors, ...
2020-05-09T15:55:41 < zyp> Thorn, the footprint is not super dense, so you don't need more than two signal layers to break it out
2020-05-09T15:55:54 < antto> Cracki wut'cha say bout my iron?
2020-05-09T15:56:02 < Cracki> thanks for the advice strata, according to that I'm a multi-pro by now
2020-05-09T15:56:02 < strata> Cracki: web devs take longer because the majority of them are hired and paid because of family connections or other non-technical reasons.
2020-05-09T15:56:06 < antto> Cracki, http://elimex.bg/userfiles/productlargeimages/product_89451.jpg
2020-05-09T15:56:16 < Thorn> zyp just don't look at layer 3, it's an absolute mess of power polygons lol (+ Vtt is on layer 4)
2020-05-09T15:56:18 < Cracki> 4pm honey, time for yo iron flattening
2020-05-09T15:56:40 < zyp> Cracki, I like just adding fresh rosin core solder for rework
2020-05-09T15:56:53 < zyp> rather than just flux
2020-05-09T15:57:09 < antto> yeah, i also just add more solder when i need flux
2020-05-09T15:57:21 < antto> or to fix a fuggly joint
2020-05-09T15:57:40 < zyp> fresh solder both adds flux and helps conduct the heat
2020-05-09T15:57:43 < Cracki> from watching The Rossmann I learned that you need good flux, IPA, qtips, good fine wick, a non-shit iron, maybe even a hotplate to keep the board and ground planes cozy
2020-05-09T15:57:47 < strata> Cracki: you are multi-pro-level based on the technical acumen you present in the chan. your responses to questions indicate a wide spectrum of knowledge backed with experience you could only have gained by spending more than 1000 hours in the craft.
2020-05-09T15:57:58 < Cracki> and that's not even touching into pcb surgery which I will never attempt
2020-05-09T15:58:00 < boddax> Jerry Walker still this channel ?
2020-05-09T15:58:18 < Thorn> zyp except I'm not sure what core thickness they have, normally you have 100µm between signal & reference, but in a standard 4 layer pcbs it's 250µm iirc. and their diff pairs don't look any wider than on a 6-layer pcb
2020-05-09T15:58:32 < Cracki> well I'm certainly more than 10kh into programming in general. it's "native speaker level"
2020-05-09T15:58:40 < Thorn> so I'm not even sure 4 layers would save cost because it might need to be non-standard

2020-05-09T15:58:44 < Laurenceb> seems legit
2020-05-09T15:58:52 < Cracki> "webshit trannies" as you so eloquently put it, probably need a dictionary wherever they go
2020-05-09T15:59:16 < Cracki> oh hey Laurenceb, got a download link for that thing? I only have the ~26 minute version ("part 1")
2020-05-09T15:59:21 < zyp> Thorn, there is no standard 4L, you'll have to look at the actual stackup your fab offers, unless you're a moneyed westerner who gets to tell the fab what stackup to use
2020-05-09T15:59:26 < strata> Laurenceb is a plandemic. It's why they cal him Laurencovid-19b
2020-05-09T15:59:47 < Laurenceb> Cracki: I hope you only want to watch ironically
2020-05-09T15:59:52 < Thorn> well e.g. jlcpcb only had 1 stackup last time I looked
2020-05-09T15:59:58 < Cracki> I don't even plan to watch it, just download it
2020-05-09T16:00:05 < zyp> Thorn, they have two for 4L and one for 6L

2020-05-09T16:01:36 < zyp> Thorn, tl;dr: 4L is offered with 0.1mm and 0.2mm, 6L only with 0.1mm
2020-05-09T16:01:51 < zyp> I'm planning to design for 0.1mm
2020-05-09T16:01:54 < antto> loirens accumulates data but sends it periodically in Burst mode

2020-05-09T16:02:53 < Cracki> TMI is his russian grrl in the vent ducts sharing the photos she took of him doing his thing in front of the computer if you know what I mean
2020-05-09T16:03:06 < Laurenceb> keeek
2020-05-09T16:03:25 < Thorn> why do they offer a choice of the middle core? so that you can have 0.8, 1, 1.2, 1.6, 2mm overall thickness. when does it matter?
2020-05-09T16:03:41 < Laurenceb> Cracki: I realised she had Stephen Covey books
2020-05-09T16:03:43 < Thorn> smaller distance between planes -> better decoupling?
2020-05-09T16:03:48 < Cracki> if you want something other than 1.6mm total thickness
2020-05-09T16:03:58 < Laurenceb> never paid attention to the shit on her desk at the time
2020-05-09T16:03:59 < Cracki> some want thinner boards because crammed case or sth
2020-05-09T16:03:59 < antto> thicc-ness
2020-05-09T16:04:19 < zyp> Thorn, board thickness matters if you wanna stick the card edge in a connector
2020-05-09T16:04:29 < zyp> e.g. pcie cards are 1.6mm, m.2 cards are 0.8mm
2020-05-09T16:04:35 < Thorn> all I want is something mechanically strong and with no negative influence on my SI
2020-05-09T16:04:40 < zyp> also matters for mechanical rigidity
2020-05-09T16:04:54 < Thorn> and PI
2020-05-09T16:05:13 < zyp> I'd go for 1.6 for anything where there's not a reason to choose anything else
2020-05-09T16:05:26 < Thorn> yeah 1.5/1.6 seems to be the standard
2020-05-09T16:05:57 < Thorn> oh btw gcc 10.1 with coroutines released 2 days ago (not for arm-none-eabi yet though)
2020-05-09T16:06:26 < antto> will senpai be eggscited?
2020-05-09T16:06:34 < Cracki> none eabi with left arm
2020-05-09T16:06:37 < Thorn> ok so 4 layers with 0.1mm does exist, ticked that box
2020-05-09T16:09:06 < Thorn> btw mp1 uses over 35 caps for Vcore and Vdd decoupling, all of them 1µF
2020-05-09T16:09:10 < Thorn> why 1µF
2020-05-09T16:10:44 < Thorn> a reel of 0402 1µF starts from $24 even in lcsc
2020-05-09T16:15:53 < zyp> Thorn, nice
2020-05-09T16:16:42 < antto> twenny fo', fo real?
2020-05-09T16:17:13 < antto> Thorn no 100nF ones?
2020-05-09T16:21:40 < Thorn> antto ddr chip and other stuff need 100nF but not the mp1 itself. a reel of 100nF is $8 and up
2020-05-09T16:22:13 < Thorn> 0402 because they need to feet between 0.8mm spaced vias
2020-05-09T16:22:16 < Thorn> *fit
2020-05-09T16:28:12 < zyp> hmm
2020-05-09T16:28:54 < zyp> https://www.te.com/usa-en/product-1888946-2.html <- when this thing says «contact current rating: 22A», what do they count as a contact? :p
2020-05-09T16:29:26 < zyp> it has three positions with 2x3 contacts each
2020-05-09T16:39:29 < zyp> looks like it's 22A per each set of three

2020-05-09T18:41:59 < aandrew> she also says things like "oh sugar!"

2020-05-09T18:44:40 < aandrew> "ze kahr iz on ze Fritz!" ?
2020-05-09T18:45:03 < PaulFertser> I guess that one, yes. No idea about the background of that video, it just looked odd.
2020-05-09T18:45:56 < PaulFertser> Weird he was saying "the Fritz" because in German they wouldn't say "der Fritz" either.

2020-05-09T23:46:48 < invzim> Great for 'electronics' stuff
2020-05-09T23:46:55 < zyp> I feel there isn't really a lot of room between a manual screwdriver and a normal size battery drill for another power tool

2020-05-10T01:56:08 < catphish> i love FPGA
2020-05-10T01:56:18 < catphish> i've never found a real use for mine, but it's cool
2020-05-10T01:57:17 < zyp> which one do you got?
2020-05-10T01:57:26 < catphish> and yes, i was pleasantly surprised by the lack of trial and error needed for moderately complex tasks
2020-05-10T01:57:39 < zyp> well
2020-05-10T01:58:21 < zyp> for me I've been thinking about getting into fpgas multiple times before
2020-05-10T01:58:57 < catphish> i have a spartan 7 and a zynq
2020-05-10T01:58:57 < zyp> I bought my first fpga devboard almost 13 years ago :)
2020-05-10T01:59:10 < catphish> (arty s7 and zybo boards)
2020-05-10T01:59:22 < zyp> picked up some basic verilog, tried some demos, but I didn't really get anywhere with it
2020-05-10T01:59:48 < zyp> that was a spartan 3e starter kit
2020-05-10T02:00:05 < catphish> what are you using now?
2020-05-10T02:01:15 < zyp> then I apparently both picked up the icestick in 2014 and made a spartan3a board of my own
2020-05-10T02:02:08 < zyp> I don't remember ever doing something with the icestick until recently though, did some basic stuff on the spartan3a before I got tired of the tools
2020-05-10T02:03:26 < zyp> oh, and I got the parallella from the kickstarter in 2013 or so, that one has a zynq
2020-05-10T02:03:32 < zyp> don't think I ever powered that up
2020-05-10T02:03:45 < zyp> but yeah
2020-05-10T02:05:08 < zyp> I started hacking with this usb stuff on the icestick before I went on vacation, picked up a tinyfpga-bx while on vacation, and when I came home I also had one of those cheap ecp5-based led matrix driver boards waiting for me in the mail
2020-05-10T02:05:14 < zyp> playing around with the latter now
2020-05-10T02:05:24 < zyp> (colorlight 5a-75b)
2020-05-10T02:06:03 < zyp> not having to deal with vendor toolchains makes it a lot more hassle-free
2020-05-10T02:06:44 < zyp> and actually having a goal helps too
2020-05-10T02:07:12 < catphish> all lattice?
2020-05-10T02:07:41 < zyp> the icestick, tinyfpga and colorlight are lattice
2020-05-10T02:07:46 < catphish> what are you using that doesn't need a vendor toolchain?!
2020-05-10T02:08:08 < zyp> both ice40 and ecp5 are well supported by opensource toolchains now
2020-05-10T02:08:16 < catphish> not that i particularly dislike xilinx's, but it's pretty slow and bulky
2020-05-10T02:08:24 < zyp> yes
2020-05-10T02:08:53 < catphish> what board would you recommend for that?
2020-05-10T02:09:01 < catphish> i might have a play
2020-05-10T02:09:04 < zyp> although, I'm going to have to give Vivado a try, I bought an artix-7 based board the other day :p
2020-05-10T02:09:12 < zyp> the colorlight
2020-05-10T02:09:24 < catphish> i've only used vivado, it's a beast, but it's also very good

2020-05-10T02:11:24 < strata> lulzcopter
2020-05-10T02:11:27 < strata> how much is the FPGA?
2020-05-10T02:11:31 < catphish> that's kinda cool
2020-05-10T02:12:28 < zyp> https://bin.jvnv.net/file/hjvtr.jpg <- I modified mine to give me 24 IO lines at 3.3V, plenty for what I do so far

2020-05-10T02:47:08 < Mangy_Dog> so much so im starting to considder making the caps and resistors smaller :/
2020-05-10T02:47:13 < kakimir> use smaller alternatives
2020-05-10T02:47:35 < kakimir> maybe flash you can keep as so8
2020-05-10T02:47:47 < Mangy_Dog> i dont think there are any smaller alternatives

2020-05-10T02:49:42 < Mangy_Dog> true

2020-05-10T02:49:57 < Mangy_Dog> and what do you mean mcu it?
2020-05-10T02:50:04 < kakimir> decode in mcu
2020-05-10T02:50:18 < Mangy_Dog> im uing the f103
2020-05-10T02:50:24 < Mangy_Dog> dont think its powerufl enough for that
2020-05-10T02:50:29 < Mangy_Dog> and while being non blocking
2020-05-10T02:51:46 < kakimir> beef up mcu
2020-05-10T02:52:10 < kakimir> but this is not like big commercial design so maybe design choices are whatever works
2020-05-10T02:52:15 < Mangy_Dog> cant because library im using for display chip isnt written for higher end mcus

2020-05-10T12:51:39 < PaulFertser> This PSL design is pure linear.

2020-05-10T13:39:47 < sync> PaulFertser: the analol supply looks neat but I don't get why he used such a strange output circuit
2020-05-10T13:42:11 < PaulFertser> sync: I'm not an EE so can't tell. What's for sure is that the circuit is not random or silly, he was modelling it a lot, and also comparing (and taking inspirations from) solutions used in professional lab equipment.
2020-05-10T13:54:14 < jadew> which one?
2020-05-10T13:54:21 < jadew> the one from the eevblog link?
2020-05-10T13:55:37 < jadew> about that one from crowdsupply... I've seen it a lot, but has anyone reviewed it?
2020-05-10T13:55:47 < jadew> the first variant had an arduino in it...
2020-05-10T13:56:15 < jadew> which makes you question the ability of the engineers from the get go
2020-05-10T13:57:05 < zyp> idk
2020-05-10T13:57:49 < jadew> it could be just a pretty layout and UI, and still amount to a pile of shit as a PSU
2020-05-10T13:58:52 < zyp> doesn't seem unreasonable to me if somebody with their skills focussed on analog design chooses an arduino for the digital part
2020-05-10T13:59:40 < jadew> sure, but it's also not unthinkable that it's one of those "best project for a beginner" followed by "I should make this into a product"
2020-05-10T13:59:50 < zyp> true
2020-05-10T14:00:12 < PaulFertser> jadew: the one from eevblog
2020-05-10T14:00:35 < jadew> food time, ttyl
2020-05-10T14:00:42 < zyp> the thing that I don't like so much about the BB3 is that it's a custom enclosure, would be neater if it fit in a standard subrack system or something
2020-05-10T14:34:17 < jpa-> jadew: i think using an arduino may have been chosen so that it signals to people "look, this is just an arduino, if you need to modify the code you'll totally be able to do it".. except that in practice, a lot of arduino code turns out to be such garbage that i wouldn't want to touch it
2020-05-10T14:38:11 < jpa-> sync: what part of the PSL-3604 output circuit seems strange to you? it looks like a quite neat way to switch automatically and without glitches between the various transformer taps
2020-05-10T14:39:56 < jpa-> if i understand it correctly, VT7 provides gate voltage to four fets VT11-VT14, each of which acts as a source follower from its own voltage rail; each voltage rail has diodes (three paralleled, probably for load sharing) to prevent the higher voltages flowing back into it
2020-05-10T14:41:19 < jpa-> when target output voltage exceeds e.g. V1 rail, VT14 is in full conduction and VT13 works as a source follower to control the output voltage
2020-05-10T14:42:30 < jpa-> and if it is carefully designed like PaulFertser suggests, it could switch very fast from e.g. highest voltage to very low voltage when current limit is exceeded - many other power supplies have significant delay in that
2020-05-10T14:53:20 < sync> yeah jpa-, that seems strange to me
2020-05-10T14:53:25 < sync> but it is quite need, yes
2020-05-10T14:53:32 < sync> neat even
2020-05-10T14:54:14 < jpa-> yeah, i have to say i haven't seen such stacked set of voltage followers before
2020-05-10T15:19:09 < Mangy_Dog> Time to bring on the pain......... Nearly all resistors are now 0402 with most caps now being 0603 and only a very few 0805  https://cdn.discordapp.com/attachments/462363010116223006/709015819798970419/unknown.png

2020-05-10T16:23:43 < mawk> cuz it's lp
2020-05-10T16:24:44 < Thorn> plz elaborate
2020-05-10T16:30:52 < mawk> it's just a suggestion, I don't actually know
2020-05-10T16:30:58 < mawk> but if it's low power it makes sense there are restrictions

2020-05-10T16:44:51 < Cracki> pls dunk on beaglebone I am interested in hearing some moaning
2020-05-10T16:44:54 < Laurenceb> Steffanx: never

2020-05-10T16:46:10 < englishman> speaking of opensores laptops, has anyone seen the pinephone
2020-05-10T16:46:10 < Laurenceb> how do I control loop
2020-05-10T16:46:24 < Cracki> ¿que?
2020-05-10T16:46:25 < specing> englishman: yes. 4GB ram meh
2020-05-10T16:46:40 < Cracki> wat do control loops have to do with a beaglebone
2020-05-10T16:46:53 < Laurenceb> talking about ventilators and iot
2020-05-10T16:46:56 < Cracki> ah
2020-05-10T16:47:13 < englishman> $150 and the same specs as the new iphone SE tho
2020-05-10T16:47:23 < englishman> surely lunix doesnt need more than 512 bytes ram??
2020-05-10T16:47:28 < Cracki> wait they get funding for doing a NSA-powered thermostat?
2020-05-10T16:47:40 < Cracki> that's almost as bad as the 1000 bucks juice press
2020-05-10T16:47:43 < Laurenceb> Cracki: stock beaglebone cannot: run from battery, charge battery, run RTC, wake or shutdown
2020-05-10T16:47:55 < Cracki> y u no run rtc
2020-05-10T16:48:21 < Laurenceb> I still havent been able to fix rtc, gave up at that point
2020-05-10T16:48:23 < Cracki> unless they gave it a battery charging ic, I wouldn't expect it to run from a battery
2020-05-10T16:48:29 < Laurenceb> it needed a kernel recompile to fix that one
2020-05-10T16:48:31 < Cracki> or, well, chage one anyway
2020-05-10T16:48:34 < Laurenceb> but they did
2020-05-10T16:48:50 < Laurenceb> it has pmic and all the peripherals to do all of that
2020-05-10T16:48:54 < Cracki> how many board revisions exist of that thing
2020-05-10T16:49:06 < Laurenceb> dunno, maybe they fixed it more recently
2020-05-10T16:49:11 < Cracki> (are we talking about the bb black or some other bb)
2020-05-10T16:49:22 < Cracki> ok so early adopters got burned
2020-05-10T16:49:23 < Laurenceb> I drilled out some vias and added jumpers
2020-05-10T16:49:26 < Laurenceb> bb black
2020-05-10T16:49:27 < Cracki> sounds like dickstarter
2020-05-10T16:49:32 < Cracki> they got blacked
2020-05-10T16:49:53 < Laurenceb> heh
2020-05-10T16:50:05 < Laurenceb> mine is now almost ok, just no rtc
2020-05-10T16:50:24 < Laurenceb> it can run in a sealed box with just a usb charge socket and power on/off button
2020-05-10T16:50:34 < Laurenceb> something rpi will never achieve
2020-05-10T16:51:47 < Cracki> ti cortex a8, ic ic

2020-05-10T16:56:44 < Ultrasauce> who needs peripherals when you can bitbang literally everything with 10% efficiency and 10x the bugs
2020-05-10T16:57:38 < Cracki> that source example for propeller on wikipedia smells almost like vhdl
2020-05-10T16:58:13 < Cracki> pascalish syntax, and wtf toll your own counter, I guess they thought fuck peripherals, let's move towards fpga
2020-05-10T16:58:30 < Cracki> *roll
2020-05-10T16:59:40 < Cracki> heh, fuck interrupts, we'll just send one "cog" to wait for an edge
2020-05-10T17:01:33 < Cracki> that actually moves back in the hw direction again on the hw-sw axis of abstractions. "normally" the concurrency is done with context switching (interrupts, tasks)

2020-05-10T17:02:18 < Cracki> "low energy standards" meaning brick and mortar?

2020-05-10T17:03:51 < Ultrasauce> its not magical thinking at all
2020-05-10T17:03:52 < Ultrasauce> it's marketing
2020-05-10T17:04:31 < Ultrasauce> the vendors don't need to believe it will do all these things to make the sale, and they don't

2020-05-10T17:10:03 < Steffanx> Cant*
2020-05-10T17:10:59 < Ultrasauce> you are well aware of how many dimensions 'better' has
2020-05-10T17:11:21 < Thorn> what is PRU in sitara? what cpu architecture is it?
2020-05-10T17:12:43 < Steffanx> In this case there can only be one, Mr Sauce

2020-05-10T17:30:13 < zyp> Cracki, fun fact, some of the other TI SoCs have cortex-m cores instead of the PRUs
2020-05-10T17:31:16 < Cracki> oh, prus aren't cortex m? at least it's some type of 32 bit risc

2020-05-10T17:41:28 < sync> yes specing, that is why there are companies that spray the underside of UK wood flooring with PU foam
2020-05-10T18:14:25 < Laurenceb> sounds like a bad idea tbh
2020-05-10T18:14:55 < Laurenceb> you are supposed to do full moisture assessment etc for building regs
2020-05-10T18:15:24 < Laurenceb> but thats the only part of building regs that refers to closed sores ISO standards
2020-05-10T18:15:29 < Laurenceb> rage inducing
2020-05-10T18:16:16 < Cracki> is that even allowed, *law* referring to something that's not free of charge?
2020-05-10T18:16:31 < Laurenceb> I thought not in uk, but apparently not
2020-05-10T18:16:49 < Cracki> maybe the ones responsible just dgaf
2020-05-10T18:16:50 < Laurenceb> you have to follow ISO standards for moisture control
2020-05-10T18:16:54 < Laurenceb> yeah
2020-05-10T18:17:17 < Cracki> I see that all the time at uni, people write absolute shit for "rules" and shrug when you want it changed
2020-05-10T18:17:38 < specing> Laurenceb: isn't that like having to follow the law, without being able to see the law?
2020-05-10T18:18:46 < Laurenceb> they seem to be careful elsewhere in building regs to keep it open sores
2020-05-10T18:19:03 < Laurenceb> specing: yeah, but look at CE, EU loves that sort of stuff
2020-05-10T18:19:13 < Laurenceb> aha found my notes on this
2020-05-10T18:19:51 < Laurenceb> uk gov bypassed the "pay to read the law" problem by publishing a perman00b .xls reimplementation of the iso standards for moisture
2020-05-10T18:21:10 < Laurenceb> also my local building inspector is a pretty cool guy, most of the time he was like "yeah thats good, you know what ur doing"
2020-05-10T18:21:30 < Laurenceb> inb4 grenfell tower
2020-05-10T18:22:05 < specing> has anyone been convicted yet for that tower?
2020-05-10T18:26:16 < specing> "In March 2019, it was revealed that no criminal charges are due to be brought before late 2021.

2020-05-10T23:39:07 < catphish> kakimir: electric?
2020-05-10T23:40:54 < catphish> we have a sort of lockdown
2020-05-10T23:41:48 < catphish> "lockdown light"
2020-05-10T23:42:26 < Steffanx> Cant even drive your bike around PaulFertser?
2020-05-10T23:42:34 < Steffanx> Here they never forbid that luckily.
2020-05-10T23:42:42 < Steffanx> We never had a full lockdown
2020-05-10T23:42:46 < PaulFertser> Steffanx: twice a week
2020-05-10T23:42:55 < PaulFertser> Steffanx: even a pushbike
2020-05-10T23:43:18 < PaulFertser> But I do not need to ride anywhere really since everything's closed.
2020-05-10T23:49:09 < catphish> interestingly joyriding *is* banned here
2020-05-10T23:50:14 < zyp> I love how these virtual logic analyzers allows me to instance as many channels as I want
2020-05-10T23:50:14 < englishman> i got a take-out local beer and cheese platter from a microbrewery for mother's day
2020-05-10T23:50:16 < catphish> they figured it was a needless strain on emergency services

2020-05-10T23:50:43 < englishman> for fpga? neato
2020-05-10T23:50:53 < zyp> englishman, yes, litescope
2020-05-10T23:50:56 < catphish> zyp: is that from your open source toolchain? emulated or real?
2020-05-10T23:51:48 < zyp> catphish, litescope, running on an actual fpga, probing real signals from my running usb core
2020-05-10T23:51:51 < englishman> looks similar to a logic analyzer ip block. so real
2020-05-10T23:52:05 < catphish> vivado has all that built in, but yours sounds near
2020-05-10T23:52:07 < catphish> *neat
2020-05-10T23:52:32 < catphish> how does it feed the signals back to the pc?
2020-05-10T23:52:43 < catphish> is that something that goes nicely via the programming interface?
2020-05-10T23:53:43 < zyp> catphish, any sort of wishbone bridge; AFAIK uart, ethernet, pcie and usb exists
2020-05-10T23:53:46 < zyp> https://github.com/enjoy-digital/litescope
2020-05-10T23:54:58 < zyp> ecp5 doesn't seem to have an internal jtag primitive like xilinx does, so I don't think you can communicate with the active fabric via jtag
2020-05-10T23:56:21  * PaulFertser almost never enjoys joyriding a motor bike :( Probably it's just too shitty of a bike.
2020-05-10T23:56:33 < PaulFertser> But I'm not really sure.
2020-05-10T23:58:14 < zyp> I actually haven't even tried simulating this usb core
2020-05-10T23:58:41 < zyp> I know I should, but it's more fun to test live :)
2020-05-10T23:59:50 < Steffanx> What kind of joyriding are you talking about catphish? Since here it involves driving someone's vehicle without permission
--- Day changed Mon May 11 2020
2020-05-11T00:00:18 < Steffanx> I dont see how that should not be banned
2020-05-11T00:00:26 < zyp> haha
2020-05-11T00:01:18 < zyp> I assume catphish meant to ride just for the purpose of riding, not to get anywhere
2020-05-11T00:03:26 < Steffanx> Yeah, thats why I assumed, but.. 
2020-05-11T00:04:04 < Steffanx> I'm disappointed in PaulFertser for not being clear either :P
2020-05-11T00:04:56 < PaulFertser> Steffanx: I assumed catphish knows better than me how to properly use English.
2020-05-11T00:07:09 < PaulFertser> I've read "On the road" so I know the word but I assumed it might be used for wider contexts since catphish did that.
2020-05-11T00:07:27 < mawk> isn't joyriding stealing cars catphish ? not using your own
2020-05-11T00:07:31 < mawk> so of course it's banned
2020-05-11T00:07:35 < mawk> unless you can steal cars in england
2020-05-11T00:08:51 < catphish> lol sorry, i refer to driving my own vehicles just for fun as joyriding, i usually drive them like i stole them
2020-05-11T00:09:22 < PaulFertser> :D
2020-05-11T00:12:55 < catphish> i recall when i bought my first brand new car, when i picked it up the salesperson asked if i had any questions, i asked if there was a recommended procedure for running in the engine
2020-05-11T00:13:26 < catphish> the salesperson got a senior mechanic, who told me "make sure it's warmed up fully, then drive it like you stole it"
2020-05-11T00:14:02 < catphish> turns out with modern manufacturing tolerances, many people consider this to be the correct way to treat a new engine
2020-05-11T00:15:23 < PaulFertser> The engine, probably, but what about the other parts?
2020-05-11T00:16:27 < catphish> well all the parts are going to be worn faster by high torque use
2020-05-11T00:16:45 < catphish> but then, they put tougher parts in high performance cars, so i guess it's all good
2020-05-11T00:17:34 < PaulFertser> Many car manufacturers have videos from production plants where they test each car on dyno full power.
2020-05-11T00:18:02 < catphish> i'd know by now if my car had any parts that couldn't cope at full torque :)
2020-05-11T00:18:22 < catphish> given that i will reach that several times a day during normal driving
2020-05-11T00:19:00 < PaulFertser> Most car drivers seem to prefer keeping low revs. Not sure if that's good for the engine but seems to help with the fuel consumption.
2020-05-11T00:20:44 < catphish> yes, this is probably the most efficient way to drive, and minimizes wear on most parts
2020-05-11T00:20:50 < catphish> it's also the least fun
2020-05-11T00:21:47 < kakimir> PaulFertser: get 1000cc
2020-05-11T00:22:20 < catphish> 3500rpm is more fun because it gives full boost at a moment's notice :)

2020-05-11T00:24:03 < Steffanx> How many almost dead experience did oyu have catphish?
2020-05-11T00:24:16 < catphish> only one so far :)
2020-05-11T00:24:53 < zyp> haha
2020-05-11T00:25:40 < zyp> when I picked up the egolf, my salesperson were like «since it's an electric motor, there's no running in period, so feel free to go wild»
2020-05-11T00:25:45 < PaulFertser> catphish: I'd expect the engine to wear faster at low RPM because you'd be almost always near the max torque for that RPM.

2020-05-11T00:26:33 < catphish> Steffanx: something like this when i was 18 https://imgur.com/a/2JkcPUb
2020-05-11T00:26:34 < PaulFertser> catphish: and because of that it's also less safe because you have less control over the vehicle as the engine won't be allowing neither acceleration nor deceleration in that state.
2020-05-11T00:27:20 < catphish> PaulFertser: i know high torque low rpm is better for fuel efficiency, don't know about torque though, maybe it would cause more wear
2020-05-11T00:27:25 < catphish> you may well be correct
2020-05-11T00:28:00 < PaulFertser> I almost had my car stolen one time. The door was unlocked and the wires were disconnected from the ignition lock, but no other damage. Apparently they saw mechanical lock on the clutch+brake pedals.
2020-05-11T00:28:09 < catphish> zyp: i've still not tried an elecric car :(
2020-05-11T00:28:31 < catphish> PaulFertser: that must have been quite the old car!
2020-05-11T00:28:35 < PaulFertser> So I was driving for month or so connecting those wires because I was too lazy to find out the lock pinout and to disassemble the plastic to connect it back properly.
2020-05-11T00:28:42 < PaulFertser> catphish: 1983 make
2020-05-11T00:28:43 < catphish> i've never owned a car without an RFID locked ECU
2020-05-11T00:29:02 < PaulFertser> Obviously no ECU
2020-05-11T00:29:14 < catphish> my oldest car was 1995
2020-05-11T00:30:19 < PaulFertser> And I've recently read that many cars made in russia in the 90s have RFID immobiliser integrated but most often disabled because they were too buggy :)
2020-05-11T00:32:09 < PaulFertser> The weird event was a year ago with my motor bike. It looked like someone was trying to steal just the ignition coil! It was disconnected and bent sideways.
2020-05-11T00:32:48 < PaulFertser> And no other damage too
2020-05-11T00:32:58 < catphish> how irritating
2020-05-11T00:33:15 < catphish> my motorbike is cursed
2020-05-11T00:34:49 < catphish> i bought it last autumn, rode it once, and the next day rain came, and didnt stop for long enough to ride again before winter, then, this spring, i got it out of the garage, rode it once, and the next day covid19 lockdown
2020-05-11T00:41:15 < PaulFertser> I can hardly imagine a heavy rain lasting that long.
2020-05-11T00:41:36 < PaulFertser> kakimir: so see I do not want to risk a 1000cc bike in environment like that.
2020-05-11T00:44:17 < PaulFertser> What other Kerouac's book do you recommend to read?
2020-05-11T00:45:37 < catphish> PaulFertser: it's not very heavy rain here, it's just very frequent and i really only ride in the dry
2020-05-11T00:46:11 < catphish> i've not tried a 1000cc bike, not sure why not, i like my 600 and never felt the need to upgrade
2020-05-11T00:46:42 < PaulFertser> catphish: when it's above 0C I ride in any weather if I have somewhere to go...
2020-05-11T00:46:48 < PaulFertser> Can't say I enjoy it much.
2020-05-11T00:47:18 < qyx> interesting, our 1.9tdci accelerates better at 2000rpm than at 3000+
2020-05-11T00:47:30 < catphish> PaulFertser: that's why i have a car :)
2020-05-11T00:47:44 < qyx> I mean, I would say it is quite common for diesel cars to be better at low rpm, high torque
2020-05-11T00:47:52 < PaulFertser> I do not like cars :/
2020-05-11T00:48:06 < catphish> qyx: yeah i find tdi has its peak torque at lower rpm, but i don't like it
2020-05-11T00:48:58 < catphish> diesel feels like it gives up at higher rpm where petrol just keeps on giving
2020-05-11T00:49:44 < catphish> the only downside is i occasionally forget to change gear and bounce of the rev limiter, which is ridiculously smooth in new ECUs
2020-05-11T00:49:58 < qyx> but you can go with <5L/100km consumtion, which actually gives you less CO2 emissions
2020-05-11T00:50:14 < qyx> *consumption
2020-05-11T00:50:28 < qyx> idk how are petrol engines today
2020-05-11T00:50:52 < catphish> i want to buy an evora soon, all L/100km bets are off then :)
2020-05-11T00:51:01 < PaulFertser> qyx: https://www.evodynamics.com/blogs/news/114447365-calculating-shift-points shows how to properly calculate your shifts
2020-05-11T00:51:39 < PaulFertser> qyx: so you can find graphs from your engine on dyno and see for yourself if higher torque is worth it.
2020-05-11T00:51:59 < catphish> wow, it always just seems obvious to me if i shift too early or too late, but i guess one can optimize it more precisely
2020-05-11T00:52:48 < Steffanx> lol, i just shift when i feel like it. 
2020-05-11T00:53:05 < qyx> Steffanx: same here
2020-05-11T00:53:08 < qyx> usually at 2100rpm
2020-05-11T00:53:11 < PaulFertser> Steffanx: but you're not participating in the imaginary drag racing!
2020-05-11T00:53:23 < catphish> stock golf gti has impressively flat torque http://www.goapr.co.uk/includes/img/products/dyno/20_tsi_ea888_gen3_mqb_r/20_tsi_gen3_mqb_r_s0_vs_s2_high_93_cc.png
2020-05-11T00:53:40 < catphish> but its clear from that chart one wants to shift at about 5500
2020-05-11T00:54:15 < PaulFertser> qyx: 4-5k is when I engage the clutch to start moving :)
2020-05-11T00:54:17 < Steffanx> PaulFertser, im usually much faster away from the traffic lights than the one behind me ;)
2020-05-11T00:55:25 < qyx> PaulFertser: on a petrol one?
2020-05-11T00:55:43 < PaulFertser> qyx: on a petrol 125cc 10 hp one , yes
2020-05-11T00:55:47 < qyx> hah
2020-05-11T00:55:52 < catphish> i actually struggle with pulling away, my light FWD car just cant get the grip it needs at full torque
2020-05-11T00:56:09 < zyp> catphish, stop by some time you're in Norway then :)
2020-05-11T00:56:16 < PaulFertser> catphish: I'd expect most cars to have similar to https://cdn.shopify.com/s/files/1/0707/0667/files/RCTvS_large.jpg?8618627934079941497 , so up to rev limiter it is for the fastest acceleration.
2020-05-11T00:56:33 < catphish> zyp: next time i'm up your way i'll pop in
2020-05-11T00:57:37 < catphish> yeah i don't lose much if i go right to the limiter
2020-05-11T01:00:18 < PaulFertser> Steffanx: I think most people are just saving fuel and improving safety by not pushing it hard. So you win but they do not actually play your game ;)
2020-05-11T01:01:36 < Steffanx> Haha true.

2020-05-11T01:29:42 < zyp> I've yet to own an iphone, but my impression is that apple are providing software updates for longer than most android phone vendors
2020-05-11T01:30:00 < kakimir> when apple launches a new thing your thing is automatically inferior
2020-05-11T01:30:05 < antto> kakimir don't worry, it was random
2020-05-11T01:30:26 < catphish> it's more like a buying cult, a culture of having the latest version
2020-05-11T01:30:39 < catphish> amazing marketing for what is really a great product too
2020-05-11T01:30:49 < kakimir> it
2020-05-11T01:30:57 < kakimir> it's not as bad as it used to be
2020-05-11T01:31:13 < kakimir> ie. iphones from 1-5
2020-05-11T01:32:14 < zyp> I know people who buy new android phones every year or so too, and people with old iphones, so I don't really think it's a brand thing
2020-05-11T01:32:45 < catphish> perhaps not
2020-05-11T01:33:04 < zyp> I also guess that people who have money to throw at a new phone every year would naturally throw them at a premium phone too
2020-05-11T01:33:05 < kakimir> when average person doesn't just buy 1100eur phone every year the cult has decayed
2020-05-11T01:33:26 < catphish> i always put it down to apple's marketing making a big fuss about their release cycle
2020-05-11T01:34:02 < catphish> but... i guess a big part is also telcos pushing people to lease phones with their sim contracts
2020-05-11T01:34:26 < catphish> which isn't apple specific at all
2020-05-11T01:35:11 < kakimir> in finland you cannot get phone + sim contract
2020-05-11T01:35:18 < catphish> but in my limited experience of people who buy their phones outright on a whim, the apple users are more likely to be excited by a new product launch and buy it unnecessarily
2020-05-11T01:35:24 < kakimir> banned like 10-15years ago
2020-05-11T01:36:21 < catphish> kakimir: wow, interesting, i the uk, telcos still claim the phones are "free" and sending people new ones every 2 years and just bundling the lease into their sim contract
2020-05-11T01:36:36 < kakimir> ofc not
2020-05-11T01:36:38 < catphish> it's mad how much people agree to pay monthly
2020-05-11T01:36:56 < kakimir> I pay 23eur a month for my unlimited sim
2020-05-11T01:37:09 < zyp> I think subsidized phones on a contract still exists here, but I have the impression those are not very popular anymore
2020-05-11T01:37:10 < catphish> yeah mine's about 22 GBP
2020-05-11T01:37:10 < kakimir> unlimited everything
2020-05-11T01:37:16 < BrainDamage> I pay 7 euro/month
2020-05-11T01:37:27 < BrainDamage> but I have a data cap of 30GB
2020-05-11T01:37:37 < zyp> but we've got the leasing plans here too
2020-05-11T01:37:47 < kakimir> I think mine is 50M throttled
2020-05-11T01:37:56 < BrainDamage> I never buy the phones with the leases
2020-05-11T01:37:57 < kakimir> unlimited data
2020-05-11T01:37:58 < catphish> zyp: the difference is they're no longer subsidized, rather the opposite, it's more expensive because they don't expect you to continue to use the old phone and keep paying, they pressure you to get a new one
2020-05-11T01:38:14 < zyp> yeah
2020-05-11T01:38:26 < kakimir> I bought a phone from different operator than what I used
2020-05-11T01:38:27 < Steffanx> Here a phone with a contract gives you a loan registration. Many people don't want such registration
2020-05-11T01:38:48 < zyp> my provider is awesome, they don't do leases, but they do no-interest financing
2020-05-11T01:38:49 < kakimir> 3year 0% intrest monthy pay
2020-05-11T01:39:13 < kakimir> for a phone that was already 50% off
2020-05-11T01:39:16 < zyp> kakimir, yeah, that's how I bought my phone
2020-05-11T01:39:25 < kakimir> I think I pay 9eurs a month
2020-05-11T01:39:28 < catphish> i think some people want laws here to force telcos to separate the phone lease from the sim contract, even if they're sold together
2020-05-11T01:39:39 < catphish> but i don't think it's happened
2020-05-11T01:39:55 < zyp> I pay like 171 NOK/mo or so
2020-05-11T01:40:10 < kakimir> greedy hands are already too deep in your pockets catphish
2020-05-11T01:40:12 < Steffanx> Such 0% interest deal is still considered a leas/loan/whatever the proper word is
2020-05-11T01:40:18 < Steffanx> Lease*
2020-05-11T01:40:28 < zyp> Steffanx, yes, I assume it's listed in the credit registry
2020-05-11T01:40:36 < catphish> Steffanx: i suppose the big issue is what happens at the end
2020-05-11T01:40:54 < catphish> 1) hey obviously make money, even at 0%, they make the normal retail markup on the device
2020-05-11T01:41:13 < catphish> 2) do they try to get you to upgrade when it comes to an end
2020-05-11T01:41:22 < catphish> *1) they
2020-05-11T01:42:08 < Steffanx> Yeah, that obviously have to make money on it, one way or another
2020-05-11T01:42:36 < catphish> they don't have to, it could just be a convenience to sell their sim services
2020-05-11T01:42:37 < zyp> I'm not worried about the credit registry, I'm not planning to apply for any new house or car loans any time soon, so having a bunch of small lines of credit listed shouldn't lead to any problems of any sort
2020-05-11T01:42:41 < catphish> but sure, it's a good business
2020-05-11T01:43:26 < zyp> Steffanx, they make money by keeping me from changing to a competitor with better terms
2020-05-11T01:43:31 < kakimir> are you about to wreck your credit rating zyp?
2020-05-11T01:43:45 < kakimir> BBB class zyp
2020-05-11T01:44:03 < zyp> no, I don't think there's anything wrong with my credit rating
2020-05-11T01:44:46 < catphish> i've never cared about credit ratings, i pay my loans, if the ratings don't show that i'm a good risk, that's their mistake
2020-05-11T01:44:48 < zyp> hmm, actually I'm gonna check what the registry have listed on me
2020-05-11T01:46:47 < zyp> I've got seven entries of unsecured credit
2020-05-11T01:47:54 < kakimir> more the better?
2020-05-11T01:47:59 < Laurenceb> god I hate this country
2020-05-11T01:48:01 < Laurenceb> https://ukinnovationscienceseedfund.co.uk/investment-focus/criteria/
2020-05-11T01:48:11 < Laurenceb>  "lots of money for our friends down the corridor"
2020-05-11T01:48:57 < zyp> kakimir, four credit cards, the phone, and the laptop that I also got at 0% interest
2020-05-11T01:49:00 < Laurenceb> ARPA it is not
2020-05-11T01:49:06 < catphish> insurance companies do an odd thing, if you pay monthly for insurance, they pay the underwriter for a year upfront and record that they've given you a 12 month unsecured loan
2020-05-11T01:49:15 < kakimir> four.. 4? credit cards?
2020-05-11T01:49:28 < catphish> but they conveniently forget that they owe you the exact same that you owe them
2020-05-11T01:49:39 < kakimir> like real bank cards or are some of them sort of different?
2020-05-11T01:49:56 < zyp> kakimir, well, three really, the fourth is ikea card
2020-05-11T01:50:03 < catphish> like, surely if you give each other credit for the same amount for the same period, it's hardly a loan
2020-05-11T01:50:05 < kakimir> does it have credit?
2020-05-11T01:50:26 < kakimir> some businesses have their own credit cards
2020-05-11T01:50:33 < zyp> the ikea card is like a normal credit card except it can only be spent at ikea
2020-05-11T01:50:42 < kakimir> like gas station chain card
2020-05-11T01:50:52 < zyp> yeah
2020-05-11T01:50:54 < catphish> can you not just use those store cards at other places too?
2020-05-11T01:51:01 < zyp> depends
2020-05-11T01:51:09 < catphish> i always assumed they were just regular visa or whatever
2020-05-11T01:51:16 < catphish> never had one
2020-05-11T01:51:17 < zyp> the ikea card is not
2020-05-11T01:51:29 < zyp> but others often are
2020-05-11T01:51:37 < catphish> makes sense
2020-05-11T01:52:04 < kakimir> gas is cheap
2020-05-11T01:52:12 < kakimir> I filled my mopped
2020-05-11T01:52:15 < catphish> not here
2020-05-11T01:52:17 < kakimir> under 20eur
2020-05-11T01:52:22 < kakimir> full tank
2020-05-11T01:52:31 < catphish> retailers here forgot that oil is basically free right now
2020-05-11T01:52:42 < zyp> anyway, I don't think it's weird to have a bunch of credit cards, they often have no annual fee and got various benefits
2020-05-11T01:52:46 < kakimir> they conveniently do 
2020-05-11T01:53:15 < kakimir> zyp: if compared to how many credit cards americans have
2020-05-11T01:53:36 < kakimir> I think it's not uncommon to have over 10 credit cards
2020-05-11T01:53:59 < kakimir> I don't know what percentage is bank cards of those
2020-05-11T01:54:04 < catphish> at risk of being moneyed westerner, i have never looked at credit card benefits, whatever 1% cashback or whatever just isn't worth my time to apply and care
2020-05-11T01:55:24 < kakimir> it's more of a lifestyle
2020-05-11T01:55:26 < catphish> i have one credit card that i use for basically all my purchases, it has no benefits whatsoever apart from legally mandated stuff (lenders have to take on product warranty risk if a retailer fails)
2020-05-11T01:55:35 < kakimir> where you also need to be rather rich
2020-05-11T01:55:49 < kakimir> to accumulate real benefits
2020-05-11T01:55:59 < kakimir> rich = spend a lot
2020-05-11T01:56:00 < zyp> catphish, I usually don't bother either, my main credit card is the same
2020-05-11T01:56:30 < catphish> i know some people are into air miles, never really understood that but it does sound like it might be cool if you spend a lot
2020-05-11T01:56:46 < zyp> but the other one got some interesting discounts, like «this weekend you get 20% off at store X if you pay with this card»
2020-05-11T01:57:09 < catphish> well that's cool
2020-05-11T01:57:22 < zyp> and the third one gives me miles, so I usually only use that to pay for travel
2020-05-11T01:57:47 < zyp> it's also an amex with no limit, so that's an extra benefit
2020-05-11T01:58:32 < zyp> certainly came in handy when I had to buy new plane tickets to get home from japan, because they cost more than the whole limit on my main credit card :)

2020-05-11T02:00:01 < zyp> well, it's not a credit card, you have to pay the whole amount you get invoiced
2020-05-11T02:00:29 < catphish> ah
2020-05-11T02:00:43 < zyp> but you can certainly fuck yourself over still :p
2020-05-11T02:00:57 < catphish> apparetly you can get a no limit amex credit card, but it has a $2,500 annual fee
2020-05-11T02:01:07 < zyp> mine has no annual fee IIRC
2020-05-11T02:02:05 < zyp> in 2013, I went to korea for two weeks for work, both flight and hotel was booked by some department in sweden
2020-05-11T02:02:07 < catphish> oh, a charge card rather then credit card?
2020-05-11T02:02:11 < catphish> i never understood those
2020-05-11T02:02:55 < zyp> nobody told me otherwise so I assumed everything was prepaid until I went to check out from the hotel and they wanted me to pay for the stay
2020-05-11T02:03:41 < catphish> lol
2020-05-11T02:03:55 < zyp> and I had just used half the limit on my normal credit card to order parts for a new computer, and no other cards with a high enough limit :p
2020-05-11T02:04:48 < zyp> so I had to get them to split the cost between two cards, which luckily went ok

2020-05-11T05:25:07 < jadew> hey, what are my solutions for packaging a device with an enclosure?
2020-05-11T05:25:21 < jadew> for bare PCB you can just put it in an ESD bag and then in a box, and done
2020-05-11T05:25:43 < jadew> but for something with an enclosure you have to make sure it doesn't wiggle
2020-05-11T05:26:36 < jadew> I'm thinking ESD foam, custom cut - but I don't know where to buy that from (other than china, which I want to avoid), also don't know what price to expect
2020-05-11T05:26:58 < jadew> or custom cardboard internals, which again, I'm not sure what to expect price-wise/volume-wise
2020-05-11T05:29:33 < Ultrasauce> varies pretty dramatically. if it's rigid enough and you can get exactly the right size of cardboard box you can probably get away with just a layer of bubble wrap
2020-05-11T05:29:45 < Ultrasauce> if it's more fragile and international shipping, yeah maybe cut foam is the answer
2020-05-11T05:30:31 < jadew> it's a tiny device, padding would look bad
2020-05-11T05:30:38 < Ultrasauce> another big question is whether this is just packaging for distribution, or a case for continued use
2020-05-11T05:30:53 < jadew> that is indeed a question
2020-05-11T05:31:03 < jadew> the answer is I don't know...
2020-05-11T05:31:10 < Ultrasauce> what's the product?
2020-05-11T05:31:11 < jadew> ideally I would have wanted it inside a wood box
2020-05-11T05:31:22 < jadew> it's an external prescaler, let me take a photo
2020-05-11T05:35:18 < jadew> http://5.12.190.252/stuff/prescaler.jpg
2020-05-11T05:35:46 < jadew> (final variant will have matching nuts and a label) :)
2020-05-11T05:36:58 < Ultrasauce> so more a piece of lab equipment or something that will end up in an installation, than something you'd throw in a toolbox
2020-05-11T05:37:37 < Ultrasauce> whats the price point?
2020-05-11T05:37:38 < jadew> could be both really
2020-05-11T05:38:08 < jadew> not exactly sure yet - haven't computed the BOM and production cost, but more than $200
2020-05-11T05:38:21 < Ultrasauce> so potentially worth a $20 case
2020-05-11T05:38:27 < jadew> yeah
2020-05-11T05:38:47 < Ultrasauce> https://www.plasticase.com/shop/kitcase/643-micro-kitcase/
2020-05-11T05:39:21 < Ultrasauce> this company does our shit and it's been great. custom foam inserts etc
2020-05-11T05:39:39 < jadew> that looks nice
2020-05-11T05:39:48 < Ultrasauce> a case like that with any cables/accessories would be slick as shit
2020-05-11T05:40:04 < Ultrasauce> then shipping is just a cardboard box to keep it from getting scratched in transit
2020-05-11T05:40:55 < jadew> looks very nice
2020-05-11T05:41:19 < jadew> would work better with the DC adapter, than what I had in mind
2020-05-11T05:41:44 < jadew> the wooden box didn't really seem like a good match for that
2020-05-11T05:43:59 < jadew> thanks for the recommendation
2020-05-11T05:46:17 < Ultrasauce> all the stuff in that vein i've bought from chinese vendors has just had a couple cubes of white foam supporting the corners against a cardboard box
2020-05-11T05:46:29 < Ultrasauce> boots on the smas if you're lucky
2020-05-11T05:47:17 < jadew> yeah, but I assume that stuff was a lot cheaper, right?
2020-05-11T05:48:09 < Ultrasauce> the cheesy vna was $150
2020-05-11T05:48:57 < jadew> is that the name of the product?
2020-05-11T05:49:06 < Ultrasauce> no lol N1201SA
2020-05-11T05:51:41 < jadew> I'm not even sure if I'm pricing this right
2020-05-11T05:52:14 < jadew> I think that if I were to buy it off of mouser or something like that, it would cost $1000+
2020-05-11T05:53:33 < jadew> I want to make sure the fact that it's built with high quality components and to high standards comes across
2020-05-11T05:53:44 < Ultrasauce> well the difference between it being $100 on ebay and $1000 on mouser isnt what's on the pcb i think
2020-05-11T05:54:11 < jadew> what then? because I'd like to sell it for $1000 :D
2020-05-11T05:56:03 < Ultrasauce> idk. support, documentation, building a brand...
2020-05-11T05:56:11 < jadew> the specifications are great, good connectors (actually custom made for this particular project), warranty, etc

2020-05-11T05:59:50 < jadew> that's part of the problem with the enclosure, I'm afraid that it would make it too expensive, and that's only a problem because I don't know how to sell it at a higher price
2020-05-11T06:00:14 < jadew> currently, I barely cover the production cost on most of my crap
2020-05-11T06:00:18 < Ultrasauce> well it would be part of it looking like a real tool made by a real company
2020-05-11T06:02:30 < jadew> how's that? http://5.12.190.252/stuff/prescaler2.jpg :P
2020-05-11T06:03:31 < jadew> yeah, I guess I suck at making that happen
2020-05-11T06:06:05 < jadew> still, the BOM is >$100 and I put a lot of work into it (testing and all that jazz)
2020-05-11T06:09:11 < jadew> not to mention the R&D...
2020-05-11T06:09:37 < jadew> I guess my problem with the box is that I'm not sure I'm currently selling to the right segment of the market
2020-05-11T06:10:53 < jadew> but then again, I'm only aware of those particular users, so I'm kinda stuck
2020-05-11T06:11:03 < jadew> hmm...
2020-05-11T06:12:01 < jadew> oh well, in the end I want to make it look good regardless of profit - I wouldn't want it look like shit, especially when it isn't

2020-05-11T07:09:45 < Streaker> missed a chance to call it cojonetech
2020-05-11T07:13:49 < jadew> it's pretty close tho :P
2020-05-11T07:35:21 < Cracki> for exposure maybe get listed at mouser, digikey, ... or whatever places exist that list lab equipment
2020-05-11T07:38:33 < Cracki> as for pricing, I'd consider the buyer's alternatives. how much does a ghz-counter cost vs mhz counter they already have (or scope) + prescaler
2020-05-11T07:43:00 < Cracki> keysight has 350 mhz counters, with an "optional" 6/15 ghz channel that goes individually for >1000 bucks
2020-05-11T07:44:30 < Cracki> wew 3k bucks for their 15 ghz channel kit
2020-05-11T07:45:04 < Cracki> it *does* install inside with a front panel connector
2020-05-11T07:49:52 < ds2> don't buy production stuff off D/K or mouser!
2020-05-11T07:55:58 < Cracki> for frequency counting, I just saw this "reciprocal method" for best of both worlds https://www.instructables.com/id/High-Resolution-Frequency-Counter/

2020-05-11T11:33:22 < jadew> Cracki, yeah, getting listed at a major distributor like that would be great, but I don't know how that is done
2020-05-11T11:35:36 < Cracki> if it's anything like those chinese fulfillment centers, it's a contract, they stock your stuff in their warehouse. I guess some can also treat you as the shipping center, mail you the packing slip/invoice with their letter head, and you pack it up and ship it
2020-05-11T11:36:09 < jadew> the 1k point was just an example, that's not what I'd be happy with, I'd be happy with 400-500, but I don't think I can ask that with out better exposure
2020-05-11T11:36:49 < Steffanx> Im not sure if its that great. They want the lowest price and still sell it for way more than you would
2020-05-11T11:38:02 < jadew> yeah, I've heard about that, but if they can pay me something I'm happy with, then they can sell it for whatever
2020-05-11T11:38:05 < Cracki> snazzy looks. sticker on the device in glossy, maybe one color besides black
2020-05-11T11:38:23 < jadew> the sticker is going to be matte
2020-05-11T11:38:31 < jadew> that's just a piece of paper I cut to size
2020-05-11T11:39:16 < Cracki> will that resist greasy fingers?
2020-05-11T11:39:27 < jadew> for sure
2020-05-11T11:40:16 < Cracki> I guess you'll put the serial number on the back and maybe some curves/plots or sth :>
2020-05-11T11:40:40 < Cracki> oh the SN is just three characters
2020-05-11T11:41:02 < Cracki> play it up, three chars doesn't look nearly important enough :>
2020-05-11T11:41:03 < jadew> heh, yeah, I'm just playing with the label now, and was wondering where I could put some graphs
2020-05-11T11:41:09 < jadew> on the back wouldn't be that bad
2020-05-11T11:41:15 < Cracki> thing does have a backside eh
2020-05-11T11:41:38 < Cracki> sad, no blinkenlights
2020-05-11T11:41:53 < Steffanx> Are you sure you want such specific url on your label jadew?
2020-05-11T11:42:01 < Steffanx> Urls tend to change
2020-05-11T11:42:14 < jadew> Steffanx, not my URLs :)
2020-05-11T11:42:22 < jadew> that's not as specific as you might think
2020-05-11T11:42:34 < jadew> it gets redirected to the SEO friendly URL :P
2020-05-11T11:43:00 < jadew> it's not there now, but that's how all my product URLs are set up
2020-05-11T11:43:33 < Cracki> url rewriting and even soft url matching are known technologies. I wouldn't worry so long as the url has some information content
2020-05-11T11:44:06 < Cracki> btw your error page feels a bit bare. maybe hook that up to "did you mean" type of search based on the url
2020-05-11T11:44:10 -!- Ultrasauce_ is now known as Ultrasauce
2020-05-11T11:44:39 < jadew> Cracki, good idea, I'll add it on the todo lisst
2020-05-11T11:44:41 < jadew> *list
2020-05-11T11:44:48 < jadew> there are lots of items I haven't attended to
2020-05-11T11:45:23 < Cracki> the articles section has title and published date. maybe a short preview too? first pic of the article, first sentence/paragraph or "before the break" marker, ...
2020-05-11T11:46:13 < jadew> oh, well spotted, the Articles section was an afterthought
2020-05-11T11:46:31 < jadew> the pages were there already, so I figured I'd list them somewhere so google can find them
2020-05-11T11:48:17 < Cracki> some random public domain pics to spice it up. if you can't show images of the actual HP counters you're talking about, maybe a Count Number muppet instead
2020-05-11T11:48:32 < Cracki> just my opinion, I'm weird
2020-05-11T11:48:45 < jadew> no, I can, I just didn't have the time to take the pictures I have in mind
2020-05-11T11:48:49 < Cracki> hell, random animals and nature pics would work just fine
2020-05-11T11:48:53 < Cracki> :D
2020-05-11T11:49:29 < jadew> the channel 3 FAQ needs two pictures of a 3 GHz model's front panel, and another one for the 5/12 GHz models
2020-05-11T11:49:39 < Cracki> it's like music for a film. it doesn't "say" anything but it sets the mood
2020-05-11T11:49:53 < Cracki> ye illustrations are awesome
2020-05-11T11:50:18 < jadew> It's been on the back of my mind for a while
2020-05-11T11:50:40 < jadew> since you also noticed it, I guess I have to make it top priority
2020-05-11T11:50:44 < jadew> will probably add them tomorrow
2020-05-11T11:53:25 < Cracki> when I saw the error page I looked around for a search box, didn't see one, and then scanned the menu
2020-05-11T11:53:49 < Cracki> btw, in the one article is the word "weather", probably typo of "whether"
2020-05-11T11:54:02 < jadew> yes, thank you
2020-05-11T11:54:26 < jadew> fixed
2020-05-11T11:55:27 < jadew> still spelled it wrong :P
2020-05-11T11:55:49 < jadew> has to have a foreign feeling to it haha
2020-05-11T12:02:05 < Steffanx> We'll talk again in... 10 years from now jadew?
2020-05-11T12:02:35 < Steffanx> When I'm the only one that bought the item and you decided to remove the product because "no one" bought it :P
2020-05-11T12:03:05 < Steffanx> Product page*
2020-05-11T12:03:43 < Steffanx> I wouldnt type in the url anyway. I would google the company + product name
2020-05-11T12:03:53 < jadew> heh, I actually have a thing about URL consistency
2020-05-11T12:04:12 < Steffanx> Or maybe scan the QR code if its there
2020-05-11T12:04:29 < jadew> it's very important, because you want all the backlinks to still work
2020-05-11T12:05:16 < jadew> people might link to it, and that's the kind of traffic you really don't want to lose just because of a URL change
2020-05-11T12:06:42 < jadew> you think I should remove the link from the label?
2020-05-11T12:06:46 < jadew> does it look weird?
2020-05-11T12:06:58 < Steffanx> I dont see the advantage to have it therr
2020-05-11T12:07:01 < Steffanx> There
2020-05-11T12:07:27 < jadew> well, if someone posts a picture somewhere...
2020-05-11T12:08:01 < jadew> for example, if I post it on eBay, I'm not allowed to link to datasheets, but the user will know where to get it from
2020-05-11T12:08:08 < Steffanx> Then I'd still type in "cojotech whateverproduct" :D
2020-05-11T12:08:18 < Steffanx> In whatever search engine
2020-05-11T12:08:21 < jadew> yeah, me too
2020-05-11T12:08:36 < Cracki> a link suggests that the information is definitely out there, and he can google or type the link. no link means the user has to hope that googling gives a useful result.
2020-05-11T12:08:52 < jadew> right, that too
2020-05-11T12:10:05 < Cracki> that's just me but I'd move all the non-functional information to the back side. front for logo/model and input/output/1:1000 arrow etc
2020-05-11T12:10:30 < Steffanx> If Google can't find the product page the page no longer exists.
2020-05-11T12:11:01 < PaulFertser> I know one guy who made a tatoo on his hand with a QR code that contained some short link URL that should have been leading to his website. Too bad the short link service stopped working in less than a year after that :) I do not remember but probably it was one of google's services.
2020-05-11T12:11:12 < Steffanx> Or "SSSSEEEOOO" failure much
2020-05-11T12:11:16 < Cracki> so far the label isn't crowded at all. if you go for a qr code, it might get a little crowded
2020-05-11T12:11:31 < jadew> lol PaulFertser 
2020-05-11T12:12:27 < Steffanx> Haha PaulFertser 
2020-05-11T12:12:39 < PaulFertser> If I had a device like your prescaler2 I would definitely type the URL from the label directly, it's simple and clear. But I'd be annoyed seeing http:// protocol !
2020-05-11T12:13:09 < jadew> PaulFertser, so www. instead?
2020-05-11T12:13:16 < Cracki> that's not too many bits tho https://api.qrserver.com/v1/create-qr-code/?data=https%3A%2F%2Fcojotech.com%2Fetp-100&size=220x220&margin=0
2020-05-11T12:13:19 < PaulFertser> jadew: no, https:// and without www, just like have it.
2020-05-11T12:13:29 < jadew> ah, got it
2020-05-11T12:13:34 < PaulFertser> jadew: https:// would give me a clue that it's a URL of a responsible person :)
2020-05-11T12:13:49 < jadew> it actually is redirecting to https :P
2020-05-11T12:13:56 < jadew> I just save the s when typing the URL out
2020-05-11T12:14:05 < Cracki> just "cojotech.com/etp-100"? people recognize .com
2020-05-11T12:14:30 < Steffanx> Yeah that
2020-05-11T12:15:07 < Steffanx> PaulFertser: 15 years from now https will be deprecated 
2020-05-11T12:15:18 < PaulFertser> Old school web users would say there also should be some underscore (probably barely visible dotted one) but I guess modern design is against that idea.
2020-05-11T12:15:27 < Cracki> say that power jack, is that the usual barrel jacks, 5.5x2.1mm or something? if so, I'd specify polarity for tip and sleeve
2020-05-11T12:15:59 < PaulFertser> URL is a URL. There's RFC for all the parts etc. I do not thing https:// clutters the space but it clearly makes it a URL instead of some random string of characters.
2020-05-11T12:16:09 < Cracki> eh, people won't use after market power supplies :P
2020-05-11T12:16:11 < jadew> Cracki, it is
2020-05-11T12:16:59 < Steffanx> Why no cojo.tech jadew? More hipster
2020-05-11T12:17:01 < jadew> there wasn't enough room for polarity and really... if there's no polarity specified then the normal one :P
2020-05-11T12:17:23 < Cracki> tip positive seems a quasi standard
2020-05-11T12:17:26 < PaulFertser> jadew: how about the input range? I assume you have a DCDC there?
2020-05-11T12:17:30 < jadew> Steffanx, that wasn't available when I bought the website I think and I like .com better
2020-05-11T12:17:36 < jadew> it's more... established

2020-05-11T12:18:05 < Cracki> ye .com looks more official than those fancy domains that all those dickstarters have
2020-05-11T12:18:07 < jadew> you could increase the input voltage, but not by much
2020-05-11T12:18:17 < jadew> because it would get too hot
2020-05-11T12:18:32 < PaulFertser> Cracki: well, imagine you have a piece of expensive measurement equipment like that one. Would you dare just assuming the default polarity?
2020-05-11T12:18:41 < Cracki> I would not
2020-05-11T12:18:45 < Cracki> I'd look in the data sheet
2020-05-11T12:18:53 < jadew> no, you have a point
2020-05-11T12:18:55 < Cracki> and maybe the ds would tell me 9v supply are good too
2020-05-11T12:19:03 < PaulFertser> jadew: how about decreasing to 9 V? There were plenty of 9 V adapters back then.
2020-05-11T12:19:07 < jadew> I have to put it there but I don't know where so it looks good
2020-05-11T12:19:25 < jadew> PaulFertser, wouldn't work, needs 10 V internally
2020-05-11T12:19:30 < PaulFertser> Cracki: well, and if you have polarity clearly labled that'd probably spare you some effort looking for the datasheet.
2020-05-11T12:19:40 < Cracki> true

2020-05-11T12:20:54 < PaulFertser> jadew: probably input triangle can be mirrored
2020-05-11T12:21:19 < jadew> I could have a DC voltage rating in there too, like for the input, but again... space
2020-05-11T12:21:22 < Cracki> free-money-guarantee eh?
2020-05-11T12:21:23 < jadew> PaulFertser, what triangle?
2020-05-11T12:21:48 < PaulFertser> jadew: the one on the left of the INPUT word
2020-05-11T12:22:04 < jadew> ah, so it shows that it's an input? :)
2020-05-11T12:22:09 < Cracki> those arrows point to the port, OR the arrows suggest flow
2020-05-11T12:22:17 < jadew> yeah, they point to the port :)
2020-05-11T12:22:22 < Cracki> style choices
2020-05-11T12:23:03 < Cracki> if you want to be obsessing over it, I'd copy whatever the devices use that are typically used with a prescaler
2020-05-11T12:23:04 < PaulFertser> Yeah
2020-05-11T12:24:07 < Cracki> audio tech has a quasi standard pictogram language. "sticky" buttons have their position pictogrammed with a function word beside, same for blinkenlights
2020-05-11T12:24:40 < jadew> I don't think there's something similar here
2020-05-11T12:24:45 < jadew> you just get a connector :)
2020-05-11T12:25:32 < Steffanx> You wont mawk. Or did they fire you?
2020-05-11T12:28:39 < mawk> not yet Steffanx 
2020-05-11T12:28:49 < mawk> I hope they don't find out I spend my days sleeping
2020-05-11T12:28:54 < mawk> remote work doesn't really work for me
2020-05-11T12:28:56 < mawk> lol
2020-05-11T12:30:46 < Steffanx> It works for me kinda, but I dont like it. I spend my entire day "working". Instead of the usual 9-5 its more like 10-23 
2020-05-11T12:31:09 < mawk> ah you're lucky you can get up later
2020-05-11T12:31:14 < mawk> I have a video call at 9 every single day
2020-05-11T12:31:21 < PaulFertser> Please excuse my ignorance but is the device really consumes much power from the input and 27 dBm is the minimum you need to provide it?
2020-05-11T12:31:22 < Steffanx> But I've been in the office mainly for the last few weeks.
2020-05-11T12:31:25 < mawk> I usually cut my cam and smoke and wait for it to finish
2020-05-11T12:31:33 < mawk> omg I'm turning you up to RIVM
2020-05-11T12:31:55 < Steffanx> Afaik no one forbids me to be alone in the office
2020-05-11T12:32:16 < mawk> you're not alone you have your swarm of indians to do the dirty work
2020-05-11T12:33:06 < Steffanx> And this is Groningen. SARS-CoV-2 doesn't know where that is.
2020-05-11T12:33:19 < mawk> lol
2020-05-11T12:33:35 < jadew> PaulFertser, it consumes 2.5 to 3W
2020-05-11T12:33:44 < jadew> that is the maximum input level
2020-05-11T12:33:47 < mawk> covie is afraid of frysk
2020-05-11T12:33:52 < jadew> I was going to change that to say max.
2020-05-11T12:34:07 < jadew> it's the damage level
2020-05-11T12:34:18 < PaulFertser> jadew: I mean signal from the INPUT connector. You specify dBm there and I assume dBm means power, and since it's an input it's like you're consuming it from the input?
2020-05-11T12:34:39 < jadew> you are, yeah
2020-05-11T12:34:43 < jadew> I mean I am
2020-05-11T12:34:57 < jadew> but that's the absolute maximum input level
2020-05-11T12:35:18 < PaulFertser> I can understand how overvoltage can damage. But how overpowering might?
2020-05-11T12:35:30 < Cracki> is input impedance an important thing to know?
2020-05-11T12:35:36 < jadew> well, overvoltage can make it hotter than it needs to be
2020-05-11T12:35:39 < PaulFertser> (not to nitpick, asking as a software developer here)
2020-05-11T12:35:45 < Cracki> ^same
2020-05-11T12:35:54 < jadew> but over power can damage the input stage
2020-05-11T12:36:59 < zyp> PaulFertser, at a given impedance, voltage and power scales with each other
2020-05-11T12:37:07 < Steffanx> have a look at the map mawk: https://eenvandaag.avrotros.nl/coronacrisis/coronacrisis-in-cijfers/kaart-besmettingen-per-gemeente/
2020-05-11T12:37:27 < zyp> besmetting
2020-05-11T12:37:36 < Cracki> scales quadratically?
2020-05-11T12:38:00 < jadew> Cracki, yeah, impedance is important, but it's going to be specified into the datasheet, and it's the usual 50 Ohm anyway
2020-05-11T12:38:07 < Cracki> current ~ voltage or does this rf stuff behave differently
2020-05-11T12:38:15 < zyp> Steffanx, 18 hospitalized in groningen?
2020-05-11T12:38:17 < Cracki> ah, the usual :D
2020-05-11T12:38:22 < Steffanx> Yeah something like that zyp
2020-05-11T12:38:32 < Steffanx> mawk, fun "fact". Relgion is to blame for all the dark blue spot
2020-05-11T12:38:53 < mawk> yeah it's time we should criminalize that
2020-05-11T12:38:58 < jadew> PaulFertser, http://wera.cen.uni-hamburg.de/DBM.shtml
2020-05-11T12:39:38 < zyp> hmm, norway is down to 60 hospitalized in the whole country
2020-05-11T12:39:52 < PaulFertser> zyp: so if you know that your device can give more than 27 dBm and you can assume both your device's output and this device's input are 50 Ohms (which would be a sane assumption) then you'd understand that you need to make sure it's limited, I see.
2020-05-11T12:40:45 < Steffanx> mawk: The bottom one started right after carnival (catholics) ended. And the upper one is a pretty christian(catholics and whatever falls in that category) region.
2020-05-11T12:41:07 < mawk> but you have more confirmed infections than 18 Steffanx 
2020-05-11T12:41:13 < mawk> or is it cumulative ?
2020-05-11T12:41:14 < Steffanx> Yeah sure.
2020-05-11T12:41:43 < jadew> PaulFertser, yeah, +27 dBm is not that common in the lab tho
2020-05-11T12:41:58 < jadew> most signal generators that go that high barely reach +20 dBm
2020-05-11T12:42:09 < Cracki> (500 mW)
2020-05-11T12:42:12 < jadew> yeah
2020-05-11T12:42:22 < mawk> we should put the christians in some kind of camp, do you agree with my proposal Steffanx ?
2020-05-11T12:42:41 < jadew> highest signal power you usually find in a lab is ~17 dBm, from LOs of various test equipment
2020-05-11T12:42:41 < Cracki> camp jerusalem
2020-05-11T12:42:45 < mawk> then corona is solved; 100% what ethics would say we should do
2020-05-11T12:42:53 < jadew> and that prescaler is perfectly capable of handling that
2020-05-11T12:42:56 < PaulFertser> jadew: do I understand it right that your target audience clearly sees that the number is specifying the upper limit? What about the lower?
2020-05-11T12:43:06 < jadew> PaulFertser, yeah
2020-05-11T12:43:12 < jadew> the lower is more like a graph

2020-05-11T12:44:11 < jadew> it's based on the same architecture as this one: https://cojotech.com/media/datasheets/HPO-100%20-%20Datasheet.pdf
2020-05-11T12:44:18 < jadew> see page 2
2020-05-11T12:45:01 < jadew> and yeah, the target audience would know that that is max input power
2020-05-11T12:45:12 < jadew> but it wouldn't hurt if I specified it
2020-05-11T12:45:24 < PaulFertser> Nice layout
2020-05-11T12:45:35 < Cracki> what does it do above +10 dBm, start glitching?
2020-05-11T12:45:36 < jadew> on the datasheet?
2020-05-11T12:45:45 < jadew> Cracki, no, it works
2020-05-11T12:45:49 < jadew> but I can't test it above that
2020-05-11T12:45:51 < Cracki> heh

2020-05-11T12:45:59 < jadew> yeah...
2020-05-11T12:46:14 < jadew> I'm testing them all across the entire specified range
2020-05-11T12:46:20 < jadew> and if I can't test it, I can't specify it
2020-05-11T12:47:07 < zyp> hmm, where does distrelec ship from?
2020-05-11T12:47:27 < mawk> from the nearest warehouse probably
2020-05-11T12:47:37 < zyp> how many do they have?

2020-05-11T12:48:56 < mawk> they have a finnish site apparently, but it looks like a cobranding
2020-05-11T12:49:29 < zyp> didn't get an order update, but the order status says shipped, but doesn't give me a valid tracking number
2020-05-11T12:49:36 < zyp> and yeah, I'm just being impatient :p
2020-05-11T12:49:52 < zyp> the norwegian one is also cobranded as elfa distrelec
2020-05-11T12:52:59 < zyp> elfa used to be a nordic distributor, was acquired by distrelec or something around ten years ago
2020-05-11T12:53:57 < zyp> before that, they actually used to have a physical warehouse in norway where you could go pick up stuff in person
2020-05-11T12:59:31 < Thorn> seeed order still isn't moving, ordered on May 5th
2020-05-11T13:07:14 < jadew> my PCBs aren't moving either

2020-05-11T13:08:26 < jadew> "max." made it worse

2020-05-11T13:09:47 < jadew> you think they're held on purpose?
2020-05-11T13:09:52 < jadew> or they're just backed up?
2020-05-11T13:10:08 < jpa-> lack of air traffic
2020-05-11T13:10:21 < qyx> I would say there are not enough jets for them
2020-05-11T13:10:25 < jpa-> and the finnish postal service doesn't want to pay to have it delivered through china or somewhere
2020-05-11T13:10:45 < qyx> my neighbour is working here at bts airport, he said theres hardly any traffic
2020-05-11T13:11:10 < jadew> well, that's not great then...
2020-05-11T13:11:29 < zyp> my distrelec order is actually seeed stuff

2020-05-11T13:12:23 < jadew> oh, that's why you were asking about where they ship them from?
2020-05-11T13:12:29 < zyp> no
2020-05-11T13:12:35 < zyp> that was just curiosity
2020-05-11T13:12:42 < jpa-> "Integrated Arduino Coprocessor"  :D
2020-05-11T13:12:45 < zyp> digikey and mouser also have this
2020-05-11T13:12:52 < zyp> but distrelec was a bit cheaper
2020-05-11T13:13:25 < qyx> hm, 12 weeks to get a sim7000e
2020-05-11T13:15:39 < PaulFertser> Probably max can be moved under the limits block and centered, not sure if that would look better
2020-05-11T13:18:04 < zyp> are we bikeshedding jadew's label today?
2020-05-11T13:18:46 < jadew> PaulFertser, I tried that, it woudln't
2020-05-11T13:19:30 < PaulFertser> zyp: he needs pro look so can't go without IRC pro advices :)
2020-05-11T13:19:55 < jadew> exactly :)
2020-05-11T13:22:14 < qyx> ok I am out of ideas where to get those simcoms
2020-05-11T13:22:20 < Thorn> in my case the order is not even shipped, status is still "confirmed" and 4 boards in stock just like when I ordered
2020-05-11T13:22:45 < jadew> for me DHL contacted me to get the required stuff for customs
2020-05-11T13:23:52 < kakiball> morgon
2020-05-11T13:25:31 < zyp> I realized yesterday that since you can mmap pcie memory space directly in a userspace process, I can do stuff like putting my usb core on a pcie-connected fpga, and run the software stack in a userspace process
2020-05-11T13:25:43 < zyp> I just wonder how the latency is
2020-05-11T13:26:25 < zyp> not just usb even, can instance all the peripherals on a fpga and run a whole firmware in userspace
2020-05-11T13:26:43 < zyp> so naturally that's something I'll have to play around with :p

2020-05-11T19:46:00 < zyp> and that's a big cutout in the middle of the board?
2020-05-11T19:46:01 < Mangy_Dog> shouldnt be too hard
2020-05-11T19:46:06 < Mangy_Dog> yes
2020-05-11T19:46:12 < Mangy_Dog> for a lcd fpc to come through to the connector
2020-05-11T19:48:21 < jpa-> it looks like it's not gonna work out in 2 layers
2020-05-11T19:51:15 < Cracki> maybe design the cutout to have round corners
2020-05-11T19:51:53 < Cracki> they will not bother making the corners cornerish anyway but it'd make the design truer to the result
2020-05-11T19:52:26 < Mangy_Dog> the corners shouldnt be an issue
2020-05-11T19:52:35 < Mangy_Dog> i dont think there would be any traces getting THAT close

2020-05-11T19:53:27 < jadew> Cracki, you search for what you need on alibaba and get in touch with them
2020-05-11T19:53:35 < Cracki> hmmm
2020-05-11T19:53:44 < jadew> but you have to buy in qty usually
2020-05-11T19:53:46 < Cracki> what do they ask for?
2020-05-11T19:53:52 < Cracki> (money for random design)
2020-05-11T19:54:07 < jadew> depends on how many you buy and how complex it is
2020-05-11T19:54:26 < Cracki> you got an engineering sample or did they send you ??? pieces of bad quality?
2020-05-11T19:54:27 < jadew> don't expect them to be much better than what you can get locally
2020-05-11T19:54:57 < jadew> for the order that they botched?
2020-05-11T19:55:01 < Cracki> ye
2020-05-11T19:55:08 < jadew> they sent me my order and it's garbage
2020-05-11T19:55:12 < Cracki> bleh
2020-05-11T19:55:35 < Cracki> wat do, go at every piece with hand tools?
2020-05-11T19:56:05 < jadew> there's nothing I can do, I think I'll have to find another shop
2020-05-11T19:56:13 < zyp> Mangy_Dog, got a screenshot of the 2d view with the rats?
2020-05-11T19:56:35 < Cracki> word of mouth... has the shop you picked existed for a while even? they can just pop up any time, or start one, let it sit for two years idle, then use it
2020-05-11T19:56:40 < Mangy_Dog> and why is it i dont feel like i should trace width calcualtors... so my pulse peak is maybe 800ma, i round off to 1 amp... the calculators say .5mm internal .17 (2mm) external traces... yet i still feel i should use .8mm on my main power rails at least at battery end... and start to thin down after conversions...

2020-05-11T19:57:08 < jadew> Cracki, yeah, it wasn't new, good reviews, etc
2020-05-11T19:57:12 < jadew> previews order was fine
2020-05-11T19:57:16 < jadew> this one was shit
2020-05-11T19:57:32 < Cracki> ye send them pictures at least
2020-05-11T19:57:35 < jadew> in fact, on the previous order they even sent me pictures with the measurements, to show that it was in spec
2020-05-11T19:57:39 < Cracki> maybe that gets someone fired over there
2020-05-11T19:57:43 < jadew> on this one they didn't
2020-05-11T19:57:54 < jadew> I assume they made the measurements and figured they should send them anyway
2020-05-11T19:58:02 < jadew> and didn't inform me that they're shit
2020-05-11T19:58:35 < jadew> anyway, since I was going through my unopened packages from china, I found a line laser pointer
2020-05-11T19:58:44 < jadew> I think that shit is very dangerous
2020-05-11T19:59:00 < jadew> it says so on the label tbf, but jeez... that line is bright
2020-05-11T19:59:03 < jadew> and long
2020-05-11T19:59:37 < Cracki> it won't pop anyone's eyeballs like a balloon
2020-05-11T19:59:53 < jadew> sure, but it can permanently damage your eyesight for sure
2020-05-11T20:00:19 < Cracki> but only twice unless you have eyes to spare
2020-05-11T20:00:20 < jadew> I was going to use it as a guide for my paper sheer, but I guess I'll just get a different sheer
2020-05-11T20:00:28 < Cracki> you can underclock it
2020-05-11T20:00:36 < Cracki> insert weak batteries
2020-05-11T20:00:41 < jadew> heh
2020-05-11T20:00:47 < jadew> it's just the diode head
2020-05-11T20:00:51 < Cracki> or a piece of graphite-filled paper
2020-05-11T20:00:56 < Cracki> ah ic
2020-05-11T20:00:58 < jadew> at 12 mA it seems to be weak enough
2020-05-11T20:01:07 < jadew> at 11 is not visible
2020-05-11T20:01:12 < jadew> at 13 mA is too bright
2020-05-11T20:01:18 < BrainDamage> what's the total power?
2020-05-11T20:01:23 < jadew> BrainDamage, who knows?
2020-05-11T20:01:49 < BrainDamage> you know the supply power
2020-05-11T20:01:49 < Cracki> isn't light output proportional to input current? or is that input power?
2020-05-11T20:01:51 < Ultrasauce> you do with a multimeter lol
2020-05-11T20:01:58 < jadew> but imagine a continuous line, one and a half meter long, that's as bright as a bright laser pointer
2020-05-11T20:02:10 < jadew> ah, you mean the consumed power
2020-05-11T20:02:19 < jadew> let me do the math
2020-05-11T20:02:44 < jadew> 42 mW
2020-05-11T20:02:45 < Cracki> I'm surprised it would show nothing at 11 mA and 1000 suns at two more milliamps
2020-05-11T20:02:54 < jadew> but I didn't reach full power
2020-05-11T20:03:03 < Ultrasauce> its almost certainly low enough for the blink reflex to save you from permanent damage at any decent distance
2020-05-11T20:03:13 < Ultrasauce> that is a pretty weak statement though
2020-05-11T20:03:54 < jadew> it's possible that it has a DCDC converter inside
2020-05-11T20:04:10 < Ultrasauce> and a free energy generator?
2020-05-11T20:04:20 < jadew> it's 35 mm long with a 10 mm diameter
2020-05-11T20:04:48 < jadew> Ultrasauce, no, I mean that's why it might not work at 11 mA, but be super bright at 13 mA
2020-05-11T20:04:52 < BrainDamage> assuming the width is 3mm and efficiency 100%, that's a power density of of 10W/m^2
2020-05-11T20:05:02 < BrainDamage> which is megasafe
2020-05-11T20:05:24 < jadew> oh, that's good to know
2020-05-11T20:05:37 < jadew> when does it stop being safe?
2020-05-11T20:05:56 < Ultrasauce> more than an order of magnitude higher
2020-05-11T20:06:09 < jadew> 100 W/m^?
2020-05-11T20:06:17 < BrainDamage> the sun itself is 1kW/m^2
2020-05-11T20:06:28 < jadew> ah ha
2020-05-11T20:06:31 < jadew> that's good
2020-05-11T20:06:36 < Cracki> well when you look at the ground, you see ~1kW/m2 but when you look at the sun your eye boils
2020-05-11T20:06:41 < jadew> ok, then I guess it's pretty safe
2020-05-11T20:06:41 < Cracki> so those are different things

2020-05-11T20:08:07 < Ultrasauce> i do have a 100mW dpss that scares the shit out of me
2020-05-11T20:09:45 < jpa-> jadew: it probably has internal feedback photodiode and a resistor divider somewhere; you can adjust the resistor divider to adjust power
2020-05-11T20:10:20 < jpa-> but yeah, in general line lasers are somewhat safe because the beam is collimated in only one direction
2020-05-11T20:10:42 < Cracki> you'd wanna calculate the power hitting your eye. worst case say say pupil diameter 8mm, 50 sq mm, at 10W/m2 is 0.5 milliwatts... so that's safe
2020-05-11T20:10:59 < jpa-> http://essentialscrap.com/tips/laser_collimation/   you can also do this to make the beam narrower while decreasing energy
2020-05-11T20:11:06 < Cracki> if you look into it at the distance where the line is 1.5 meters long

2020-05-11T21:13:54  * srk went to buy smokes and the starobrno pub was full of people drinkin' beer :D looks like the panic is over here
2020-05-11T21:14:04 < PaulFertser> srk: for using any vehicle, yes. It's either because you have an official permit to work or you need to go to a doctor or you're a volunteer helping the elderly or you can get a permit "for other purposes" twice a week.

2020-05-11T21:15:02 < PaulFertser> sync: not really a fan of kwas. I rarely drink it. I like beer, probably too much but so far my consumption is pretty moderate.
2020-05-11T21:17:57 < PaulFertser> srk: one is legally allowed to walk a dog but within 100 m of the place of residence. And allowed to walk to the nearest shop to buy food or legal drugs. That goes without permit. But using any vehicle officially requires a permit. You go to a website and fill a form and get 16 latin letters + digits code.
2020-05-11T21:18:32 < PaulFertser> The fine is supposed to be about 50 EURs

2020-05-11T21:19:51 < PaulFertser> srk: some people get fines, that's for sure (Internet knows everything). But it's hard to tell how widespread it is, and whether you're likely to get fined if you're walking alone and not with your drunk friends.

2020-05-11T21:22:29 < PaulFertser> The app sends plenty of some data to the servers and every now and then people get push messages telling them to take a photo of themselves.
2020-05-11T21:23:32 < PaulFertser> iphone users started to receive the message even before it was added to the "app store" and after a few days when it appeared there they installed and were greeted with a fine for installing it too late.

2020-05-11T22:07:02 < Steffanx> No, but I can't say I'm a big fan of beer
2020-05-11T22:08:05 < Ultrasauce> maybe hefeweizen, nitrogenated cream ale, some variation of stout
2020-05-11T22:08:29 < Steffanx> People say you have to "learn to" drink beer. I never got to learn it :P
2020-05-11T22:08:48 < Ultrasauce> theres a local brewery that does a wheat ipa that is quite dangerous in my experience....7% and goes down like a soft drink
2020-05-11T22:09:41 < PaulFertser> Ultrasauce: wheat IPA? That's a weird combination.
2020-05-11T22:10:07 < Ultrasauce> it's really citrusey and quite cloudy
2020-05-11T22:10:12 < PaulFertser> I've never tried a wheat bear I liked.
2020-05-11T22:10:32 < BrainDamage> wheat icebock, tripel and brett sour
2020-05-11T22:11:42 < PaulFertser> How's life BrainDamage? Is there any way to drink that kind of not so common bear these days?
2020-05-11T22:12:12 < BrainDamage> I'll be able again at the end of this month
2020-05-11T22:12:28 < BrainDamage> you're allowed to walk outside now, so things are a bit less stressing
2020-05-11T22:12:32 < ds2> beer deliveries not allowed?
2020-05-11T22:12:57 < BrainDamage> allowed, but the good beer places are pub & shop
2020-05-11T22:13:08 < BrainDamage> and they cannot open one without the other
2020-05-11T22:13:40 < ds2> oh
2020-05-11T22:13:41 < PaulFertser> btw, I think lockdown in Italy was way more strictly enforced than what we have in moscow. I saw plenty of people while riding to a shop today.
2020-05-11T22:13:48 < ds2> maybe the pubs need a different business model
2020-05-11T22:14:55 < BrainDamage> brewery only is rare, nearly often it's pub + brewery
2020-05-11T22:15:46 < PaulFertser> My life hasn't changed much due to the lockdown. I was mostly sitting at home through all the winter anyway because I do not ride a motor bike when it's below 0C.

2020-05-11T22:17:28 < PaulFertser> Poor doctors, I guess their lifes has changed a lot. It must be a very tough pressure and insane schedule these days. And of course the highest risk to suffer from COVID-19.

2020-05-11T23:26:10 < Thorn> it's not commercial. not sure if I'm going to publish it but I can share
2020-05-11T23:27:55 < Thorn> right now the big problem is finding a pcb manufacturer who can make boards with required tolerances and stackup and not charge $1500 (even $150 is less than ideal lol)

2020-05-11T23:30:27 < Thorn> they aren't publishing prices but I've seen the 120 euro figure on the net
2020-05-11T23:30:47 < Thorn> wtf is going on, 0.8mm bgas have been around for over 10 years
2020-05-11T23:31:35 < qyx> 2L would be pure punk?

2020-05-11T23:44:17 < Thorn> zyp only if they still honour their 3.5/3.5 mil offer
2020-05-11T23:44:48 < Thorn> because 0.127/0.127mm isn't enough afaict
2020-05-11T23:45:47 < qyx> for 0.8 pitch?

2020-05-11T23:47:40 < Thorn> need to be able to run a trace between them spaced 0.8mm apart (between centers)
2020-05-11T23:48:36 < zyp> they offer 0.4mm vias
2020-05-11T23:48:52 < zyp> for like $15 extra AFAICT
2020-05-11T23:49:28 < zyp> ah, $30
2020-05-11T23:49:45 < zyp> 0.4mm vias implies 4-wire test which is another $15
2020-05-11T23:49:52 < Thorn> actually that's still pretty affordable compared to others
2020-05-11T23:51:06 < zyp> 100x100mm 6L with 0.4mm vias and ENIG is $135 for 5
2020-05-11T23:51:17 < zyp> that's not a bad price
2020-05-11T23:51:29 < zyp> 4L same specs is $76

2020-05-11T23:53:38 < zyp> the SOM-RK3399V2 looks fun
2020-05-11T23:54:20 < qyx> I swapped polarity on the RX pair, idk if that's the reason it doesn't work
2020-05-11T23:54:24 < Thorn> 55Ω impedance is achieved with a 0.12mm trace with their stackup, that's < 0.127mm so hopefully they still accept 3.5/3.5
2020-05-11T23:54:38 < zyp> qyx, I wouldn't think so
2020-05-11T23:55:01 < qyx> also the pcie host controller on the ralink/mediatek seems to be flawed in some ways

2020-05-12T00:11:25 < qyx> that was fast, thanks
2020-05-12T00:13:52 < zyp> since we're on the topic, where do you find mechanical dimensions for mounting holes and stuff?
2020-05-12T00:13:58 < zyp> e.g. backplane height
2020-05-12T00:14:12 < zyp> and mounting holes on pcbs
2020-05-12T00:14:31 < zyp> assuming standard mounting holes on the front panel
2020-05-12T00:15:19 < qyx> most of the things are in the schroff catalog
2020-05-12T00:16:32 < qyx> but there are drawings available on the net
2020-05-12T00:16:38 < qyx> checking if I have something in my notes
2020-05-12T00:17:04 < zyp> I've went through https://schroff.nvent.com/wcsstore/ExtendedSitesCatalogAssetStore/Attachment/SchroffAttachments/Documents/6_1_europacPRO_e_.pdf, and while it has a bunch of dimensions regarding the depth, I'm not finding so much about height
2020-05-12T00:19:00 < zyp> e.g. I see that both front panel and backplane is mounted 12.75 mm from the mounting hole for the horizontal rail, and the mounting holes are spaced 15mm apart, so front panel to backplane distance will be 2*12.75 + n*15
2020-05-12T00:22:22 < zyp> and the guide rails are using mounting holes 10mm shorter than the rail itself, so for 70mm rails, n=4, backplane to front panel is 85.5 mm
2020-05-12T00:25:56 < qyx> IEC 60917 is apparetnyl what we are looking for
2020-05-12T00:30:17 < qyx> I remember it took me some time to find all pieces of the puzzle

2020-05-12T00:43:14 < zyp> which rail mounting holes?
2020-05-12T00:43:23 < zyp> for mounting the backplane?
2020-05-12T00:43:49 < qyx> I lied, 121.95mm from the side panels for M4 screws
2020-05-12T00:44:07 < qyx> 122.50mm are M2.5 holes for backplane mounting
2020-05-12T00:44:17 < zyp> right
2020-05-12T00:44:50 < zyp> if backplane is 130mm, that doesn't leave much room for top/bottom cover

2020-05-12T01:26:00 < Laurenceb> nobody cared who I was until I put on the mask
2020-05-12T01:26:34 < specing> Dr. Laurenceb, Ph.D
2020-05-12T01:27:38 < Laurenceb> bro just use quantum chromodynamics to understand the interaction of the covid-19 virus with the HEPA filter
2020-05-12T01:30:13 < Steffanx> Yeah will do. Have a book about quantum chromodynamics for me
2020-05-12T01:30:29 < Steffanx> Or can you do a youtube course. Dont forget your balloon tie
2020-05-12T01:30:55 < Steffanx> And add some ? in those sentences
2020-05-12T01:34:07 < jadew> Steffanx, do you think I can get good results milling aluminium with one of those chinese CNCs?
2020-05-12T01:34:22 < Steffanx> Im not sure. Whats good?
2020-05-12T01:34:27 < jadew> also, how safe are those high power spindles? can they blow up?
2020-05-12T01:34:45 < kakimir> maker level
2020-05-12T01:34:49 < jadew> good is resonably fast milling and decent finish (no rattling and things like that)
2020-05-12T01:34:55 < Steffanx> jpa- has a chinese one. So did the englishguy i believe
2020-05-12T01:34:57 < jadew> yeah... maker level
2020-05-12T01:35:00 < kakimir> not machine shop level - not even close
2020-05-12T01:35:52 < Steffanx> I've seen videos with pretty acceptable results kakimir..
2020-05-12T01:35:54 < jadew> I don't think getting a real mill is a good idea atm, a CNC might prove to be more valuable
2020-05-12T01:36:00 < jadew> me too
2020-05-12T01:36:04 < kakimir> it depends steff
2020-05-12T01:36:14 < kakimir> tolerances
2020-05-12T01:36:15 < jadew> particularly on that 6040 thing, but I don't understand why
2020-05-12T01:36:20 < kakimir> surface finish
2020-05-12T01:36:23 < jadew> a smaller machine should give better results
2020-05-12T01:36:23 < kakimir> what is acceptable
2020-05-12T01:36:44 < Steffanx> What is high power jadew?
2020-05-12T01:36:55 < jadew> Steffanx, 1.5 and 2.2 kW
2020-05-12T01:37:18 < jadew> I was looking at those 2.2 kW spindles
2020-05-12T01:37:25 < Steffanx> Oh, i think we were talking about the +3.6kW ones :P
2020-05-12T01:37:42 < Steffanx> People seem fairly happy with em
2020-05-12T01:37:42 < jadew> oh, didn't know they had those
2020-05-12T01:38:02 < Steffanx> Its mainly the vfd i see complaints about
2020-05-12T01:38:25 < jadew> what's vfd?
2020-05-12T01:39:00 < Steffanx> Variable frequency drive.. the driver for those spindles
2020-05-12T01:39:10 < jadew> I was also considering getting a 6040 frame + one of these spindles: https://www.spindel-shop.de/en/High-Frequency-Spindle-standard-Series/High-Frequency-Spindle-HFS-series/
2020-05-12T01:39:17 < jadew> got it
2020-05-12T01:39:51 < Steffanx> I will try one of those somewhere in the future, but first i have to get my current setup up and running again
2020-05-12T01:40:31 < Steffanx> I will also try aluminium soon, ill probably fail terribly, but well see :D
2020-05-12T01:41:04 < Steffanx> You are acceptable kakimir :P
2020-05-12T01:41:39 < jadew> Steffanx, try one of those spindles?
2020-05-12T01:41:54 < jadew> from the link? or are you referring to something else?
2020-05-12T01:41:55 < Steffanx> Yeah
2020-05-12T01:42:05 < Steffanx> Nah just some random aliexpress one proba ly
2020-05-12T01:42:20 < Steffanx> Shipped from a eu wharehouse
2020-05-12T01:42:56 < Steffanx> Watercooled ofcourse
2020-05-12T01:44:00 < Steffanx> My air cooled router blows the shit all over the place.

2020-05-12T08:50:49 < jpa-> jadew: there is no reason why a smaller machine should give better results in this price class; the smaller ones have increasingly more plastic parts
2020-05-12T08:51:28 < jpa-> jadew: i hear CNC6040 is pretty good; my CNC3020 can get quite ok results in aluminum if one goes slow, has good CAM software and chooses the endmill carefully
2020-05-12T09:05:41 < srk> 6040 is better due to supported rails, 3020 wobbles bit too much on X

2020-05-12T10:18:15 < jadew> I saw a video on youtube with someone upgrading the bed with a steel plate
2020-05-12T10:18:44 < jadew> I'm all up for that, but I was hoping I could get away with a smaller CNC
2020-05-12T10:22:23 < jpa-> jadew: no, that's not what i meant - supported rails is great, but at least for CNC3020 the spindle is the bigger limit
2020-05-12T10:23:12 < jadew> I see
2020-05-12T10:23:31 < jadew> what spindle size do you recommend for aluminium? the bigger the better?
2020-05-12T10:23:33 < jpa-> i've been thinking about upgrading mine, but it is hard to find a good spindle in that size
2020-05-12T10:24:48 < srk> 2.2kw china watercooled ones
2020-05-12T10:24:53 < jpa-> well, size is not so important as its rigidity, torque and runout; for good torque and speed control, go for brushless; for rigidity, looks for one that has the axis and the chuck as one piece instead of held on by flimsy setscrews and glue; for runout, you can only hope for the best
2020-05-12T10:25:01 < srk> exactly
2020-05-12T10:25:05 < srk> especially for metals
2020-05-12T10:25:06 < jpa-> srk: yeah, i hear those are good, they just won't fit easily on CNC3020

2020-05-12T10:33:57 < jpa-> srk: i usually load files to it with usb cable (just normal usb mass storage), then use the encoder wheel to jog to zero x/y, then use z probe to zero z, then select the file to run
2020-05-12T10:34:16 < srk> yes I've been using it like that as well
2020-05-12T10:34:21 < srk> because USB.. :D
2020-05-12T10:34:36 < srk> but pausing and resuming when you need to adjust something
2020-05-12T10:34:37 < srk> tool changes
2020-05-12T10:34:40 < srk> all that sucks hard
2020-05-12T10:34:41 < jpa-> i don't have it close to my PC anyway, so smoothie being able to operate stand-alone is great
2020-05-12T10:34:56 < jpa-> i have different tools as separate g-code files
2020-05-12T10:35:02 < jpa-> how does pausing suck?
2020-05-12T10:35:08 < srk> yeah, I have bunch of preprocessors for that :D
2020-05-12T10:35:24 < srk> how long does it take to pause?
2020-05-12T10:35:35 < srk> till the machine stops moving
2020-05-12T10:35:36 < jpa-> umm, no time at all when i press the button
2020-05-12T10:35:46 < srk> and you can resume?
2020-05-12T10:35:50 < jpa-> or well, probably the acceleration limit so something like 0.1 sec 
2020-05-12T10:35:53 < jpa-> sure
2020-05-12T10:36:01 < jpa-> press button to pause, press again to resume
2020-05-12T10:36:15 < srk> cool, been a while since I've had that running
2020-05-12T10:36:28 < jpa-> aborting is a bit annoying in that if i'm paused and select abort from menu, it moves a tiny bit before it really aborts
2020-05-12T10:36:47 < srk> at the time I was using it, it was problematic as it had to empty the planner queue
2020-05-12T10:36:47 < jpa-> i'm also running 6 years old firmware i think

2020-05-12T10:37:48 < srk> I've contributed some patches to it as well but ^^ that guy is hard to work with 
2020-05-12T10:38:13 < jpa-> i'm running a custom fork actually, but i think all the important stuff is already fixed in mainline also anyway
2020-05-12T10:38:15 < srk> and the firmware is not that stellar and hitting the limits of the board quite hard
2020-05-12T10:38:26 < srk> especially flash wise, so no new features :D
2020-05-12T10:38:30 < srk> how's smoothie2?

2020-05-12T10:38:40 < jpa-> i haven't tried smoothie2 myself
2020-05-12T10:38:47 < srk> no it's not, for 5 steppers it's nice
2020-05-12T10:38:56 < srk> but not for all the things you want to add :D
2020-05-12T10:39:42 < srk> all in one solution won't scale as there's a limit of how much you can do on single cpu

2020-05-12T10:44:14 < srk> interesting, thanks
2020-05-12T10:44:48 < srk> what's even worse is when you want to do closed loop control for bldcs .. :D
2020-05-12T10:45:08 < srk> which is actually easier compared to stepper control 
2020-05-12T10:45:26 < srk> up to two motors per mcu :D
2020-05-12T10:45:37 < srk> maybe more on some bigger ones?
2020-05-12T10:46:03 < jpa-> IMO at that point it makes sense to use one MCU per motor - a cheap $3 STM32F334 can drive one motor very well and even has HRTIM
2020-05-12T10:46:12 < PaulFertser> srk: (failing kernel build) if you show full log I might get a clue
2020-05-12T10:46:14 < srk> yeah, exactly :)
2020-05-12T10:47:04 < srk> PaulFertser: 5.6.1 for armv6, had to run it again as I can't see the error in the scrollback :P
2020-05-12T10:47:16 < PaulFertser> srk: with -j1?
2020-05-12T10:47:17 < jpa-> and for good torque, it makes sense to put the motor driver right next to the motor - so you can have +48V at 1A or so coming in and 1V at 48A going to the motor
2020-05-12T10:47:35 < srk> jpa-: I went for stm32f765 to have some headroom for canopen 
2020-05-12T10:47:52 < srk> still porting.. :D
2020-05-12T10:48:14 < srk> but only ADC, ATIM/GTIM are remaining and I can resume servoing
2020-05-12T10:49:09 < jpa-> i just had some BLDC control project where i used STM32F334.. i thought i wouldn't need voltage sense resistors on the outputs, but turns out the power electronics weren't very linear - ended up implementing a weird DTC-SVM-combo
2020-05-12T10:49:36 < jpa-> it runs at 250kHz interrupt rate on the 64MHz CPU, takes up half of the cycles.. but doesn't matter, it has nothing else to do
2020-05-12T10:50:15 < srk> fun, I'm still newb when it comes to electronics so I was running odrives and have boostxl-drv8323 with f7 stacked as the next step
2020-05-12T10:50:58 < srk> I was curious if I could port odrivefirmwares foc to ivory/tower and it got out of hand a bit
2020-05-12T10:51:05 < jpa-> biggest thing i learned is that if motor has small inductance, putting bigger inductors on PCB reduces heating a lot
2020-05-12T10:51:32 < jpa-> originally i had 100mA idle running current for the motor, but +-500mA ripple heating it up because the inductance was too low
2020-05-12T10:53:07 < srk> hehe, I'm gonna switch to https://www.quadcopters.co.uk/mobula-7-spare-motor-se802-16000kv
2020-05-12T10:53:15 < srk> have one with broken axle, gonna be fun

2020-05-12T15:51:29 < zyp> ah, there's a character device thing too, didn't know

2020-05-12T15:52:07 < zyp> PaulFertser, what performance can be expected from those?
2020-05-12T15:52:07 < PaulFertser> zyp: libgpiod not yet merged http://openocd.zylin.com/#/c/5559/
2020-05-12T15:52:46 < PaulFertser> IIRC, quite slow, probably about 500 kHz.
2020-05-12T15:53:03 < zyp> right, that's what I figured
2020-05-12T15:53:25 < PaulFertser> Probably libgpiod should be 2x faster.
2020-05-12T15:53:48 < PaulFertser> And for specific SoCs there're few implementations working over /dev/kmem directly
2020-05-12T15:54:32 < zyp> https://www.seeedstudio.com/ODYSSEY-X86J4105864-p-4447.html <- I got this thing today and I'm gonna stick a fpga board in the m.2 slot once that arrives, and it'd be neat to do the jtag directly since there's a ton of gpio on it anyway
2020-05-12T15:55:12 < PaulFertser> libgpiod should be changing tms, tck, tdi in one syscall while sysfsgpio would require 3 syscalls.
2020-05-12T15:55:13 < zyp> and I was guessing the linux gpio would be pretty slow, so then I'm thinking to do some custom usb jtag on the ATSAMD21
2020-05-12T15:55:26 < strata> . America will have effectively a massive pool of something very much like easily, algorithmically exploited technofeudal neoserfs — people who’ve reverted to servitude to make a living, only their overseer is an app. Those “low income service jobs” are economists’ jargon for “people becoming servants again.” To whom? To a kakistocracy, if you like — a class that’s the opposite of aristocrats...
2020-05-12T15:55:26 < strata> kakistocracy!
2020-05-12T15:55:26 < strata> who do we know that is a kakistocrat?
2020-05-12T15:55:32 < zyp> it's hooked up to the x86 via usb
2020-05-12T15:55:39 < zyp> kinda neat like that
2020-05-12T15:56:30 < zyp> so, are there any convenient usb protocols I can clone to make something that'll just work with openocd, or do I have to make my own interface driver as well?
2020-05-12T15:56:34 < PaulFertser> Depends on how often you need to do those JTAG operations of course. I usually spend more time thinking and reading than waiting for compilation/flashing/whatever
2020-05-12T15:57:26 < zyp> true
2020-05-12T15:57:29 < PaulFertser> New cmsis-dap/daplink protocol probably.
2020-05-12T15:58:18 < PaulFertser> It supports raw jtag
2020-05-12T15:58:43 < PaulFertser> No support in OpenOCD yet though http://openocd.zylin.com/#/c/4831/
2020-05-12T15:59:34 < zyp> hmm, I guess quickest solution might be just writing my own svf player
2020-05-12T16:01:07 < qyx> zyp: sysfsgpio on a f1c100s gives about 1.6KB/s flashing speed
2020-05-12T16:01:36 < PaulFertser> Well, I've fixed few bugs in OpenOCD's player over they years; not sure if your implementation is going to be perfect right away. OTOH you'll be needing only a limited set of functionality (just SVF files generated for your target FPGA with specific software).
2020-05-12T16:01:47 < qyx> bcmxxxx implementation on a RPi was considerably faster
2020-05-12T16:02:27 < zyp> yeah
2020-05-12T16:02:35 < PaulFertser> zyp: another protocol worth considering is jlink, it's well-documented and you need just the raw jtag parts from it.
2020-05-12T16:02:52 < zyp> hmm, since it's a xilinx fpga, I guess xsvf is also an option
2020-05-12T16:03:02 < zyp> and I already wrote a xsvf player years ago
2020-05-12T16:03:04 < PaulFertser> Old cmsis-dap protocol is ok but goes over HID. Supports raw jtag too.
2020-05-12T16:03:44 < PaulFertser> Why make your own on an MCU if you can add ft232h ?
2020-05-12T16:04:28 < zyp> because there's already an onboard MCU, saves hooking up an extra device
2020-05-12T16:05:47 < specing> also ftdi is frickin expensive
2020-05-12T16:06:42 < PaulFertser> specing: compared to a custom m.2 board with FPGA, not really.
2020-05-12T16:07:28 < zyp> PaulFertser, also, for other projects the mcu could do other stuff as well
2020-05-12T16:07:32 < zyp> e.g. power management
2020-05-12T16:08:21 < PaulFertser> I have a feeling implementing the minimum of jlink protocol and using openocd player should be faster than doing it all on your own. I might be very wrong of course, but I'd take a look at their protocol datasheet, that won't take much time.
2020-05-12T16:11:54 < zyp> could be
2020-05-12T16:12:15 < zyp> but I don't think I'm gonna spend time on that today
2020-05-12T16:13:08 < zyp> before anything I'd have to add support for the atsam usb core in my usb stack, and I should probably get a standalone atsam board before I do that, so I can plug it in the usb analyzer

2020-05-12T19:41:49 < Cracki> unless it's doing critical calculations that must not go wrong, i'd go for faster rather than ecc
2020-05-12T19:42:25 < Cracki> we put together a video editing computer some months ago. ryzen 3900x, 32 gb of 3600 mhz non-ddr
2020-05-12T19:42:41 < mawk> or if you live in australia
2020-05-12T19:42:52 < mawk> with all those bad cosmic rays
2020-05-12T19:42:52 < Cracki> some noob wanted us to get an nvidia 1660. we went for the 2070 super
2020-05-12T19:43:11 < jpa-> well, it's a workstation; if it crashes, it could easily set me back by half an hour - if ECC saves one crash over the system lifetime (a couple of years), it will have paid for itself
2020-05-12T19:43:43 < Cracki> he was one of those open sores nutjobs and had some feeling of disgust over the tensor cores and the raytracing, so he wanted us to have inferior hardware where open sores could "compete" with commercial software because commercial software would wipe the floor with it given decent hw
2020-05-12T19:44:15 < Cracki> fair enough
2020-05-12T19:44:26 < zyp> jpa-, then consider all the time you're losing by having to wait for the additional memory latency
2020-05-12T19:44:32 < Cracki> cl16 vs cl19 is 15% lower latency for first access
2020-05-12T19:44:52 < jpa-> zyp: yeah, that's what makes the decision difficult :)
2020-05-12T19:45:17 < jpa-> Cracki: 15% of the CL latency, but isn't the total latency a lot higher anyway
2020-05-12T19:45:27 < Cracki> so consider if you're doing much scatter/gather ram access or not. scientific workloads consider that. miscellaneous desktop applications aren't pushing it
2020-05-12T19:45:32 < zyp> is ecc vs non-ecc same pinout for normal dimms?
2020-05-12T19:45:41 < zyp> for sodimm it's apparently completely different
2020-05-12T19:45:47 < jpa-> zyp: at least the motherboard claims to support both
2020-05-12T19:46:09 < Cracki> CL19 for 2666 mhz, iirc, means 22.8 ns
2020-05-12T19:46:18 < Cracki> (1/2666e6 * 19 * 2)
2020-05-12T19:46:30 < Cracki> cl16 is 19.2 ns
2020-05-12T19:46:54 < Cracki> that's like "seek time"
2020-05-12T19:47:08 < jpa-> yeah, but isn't there already a bunch of latency internal to the CPU and also to actually transfer the data - both of which will be equal irrespective of CL timing
2020-05-12T19:47:21 < jpa-> so i wonder if it is really 122.8 ns vs. 119.2 ns
2020-05-12T19:47:25 < Cracki> benchmarks like "stream triad" are bus frequency bound
2020-05-12T19:47:35 < Cracki> no, the order of magnitude is 10-20 ns
2020-05-12T19:47:58 < Cracki> unless something is done ten times
2020-05-12T19:48:41 < jpa-> https://www.anandtech.com/show/12625/amd-second-generation-ryzen-7-2700x-2700-ryzen-5-2600x-2600/3  says 66ns total latency
2020-05-12T19:49:02 < Cracki> ah you're adding 100ns. I doubt there's 100ns of waiting anywhere in the path to ram
2020-05-12T19:49:56 < jpa-> yeah 100ns was a guess before googling; with the ~66ns the difference would be just 6%
2020-05-12T19:50:41 < Cracki> i'm scanning the article for the source of their 66ns claim, and what all it includes
2020-05-12T19:51:01 < jpa-> the source is apparently AMD's slides
2020-05-12T19:51:21 < Cracki> the typical file format for leaked infos

2020-05-12T19:54:23 < zyp> more like not anywhere
2020-05-12T19:54:41 < zyp> your ground pour looks useless, it's not stitched
2020-05-12T19:54:54 < Mangy_Dog> stitched?
2020-05-12T19:55:34 < zyp> connected in a way that would actually make it work like a ground plane
2020-05-12T19:56:02 < Mangy_Dog> its connected between layers where i can
2020-05-12T19:56:12 < jpa-> though it looks like you would have space to put some ground wires along your buses, that would help
2020-05-12T19:56:13 < Mangy_Dog> i might be able to improove more
2020-05-12T19:56:24 < Mangy_Dog> right now im just celibrating the fact i managed to route the entire rats nest
2020-05-12T19:56:34 < Cracki> jpa-, I forgot that I saw this before. made me choose >=3200 and not even consider 3866+ https://www.reddit.com/r/Amd/comments/bz5b7x/ryzen_3000_ddr_memory_latency_comparison/
2020-05-12T19:56:39 < jpa-> yeah, the routing looks neater than what i expected
2020-05-12T19:56:52 < Mangy_Dog> jpa dont look too closely :p
2020-05-12T19:57:00 < Mangy_Dog> theres a few not so neat bits
2020-05-12T19:57:19 < karlp> last time I looked at Cas latency it seemd that it was "irrelevant" tehse days and just for pixel peepers/gaymer types to wank over
2020-05-12T19:57:25 < Mangy_Dog> if money was no object i would have just done a 4 layer board
2020-05-12T19:57:26 < Mangy_Dog> but im poor
2020-05-12T19:57:55 < karlp> if you'd bought genuine parts the first time, you'd have money left over still for 4 layer ;)
2020-05-12T19:58:09 < Mangy_Dog> pft:p
2020-05-12T19:58:34 < Mangy_Dog> ummm
2020-05-12T19:58:37 < Mangy_Dog> damn
2020-05-12T19:58:41 < Mangy_Dog> did i make that order from lscs
2020-05-12T19:58:53 < Mangy_Dog> i actually cant remember :/
2020-05-12T19:59:05 < Mangy_Dog> gah lcsc
2020-05-12T19:59:26 < jpa-> but yeah, disable the ground pour so that you can see and route GND wires along the buses, and it should be pretty ok
2020-05-12T19:59:37 < Mangy_Dog> yeah i did that too
2020-05-12T19:59:52 < Mangy_Dog> but ill see if i can fill in any other areas just cus...
2020-05-12T20:03:19 < jpa-> also, what weird stuff connects to the pin headers along the board side, why is there no GND connections there?

2020-05-12T20:53:48 < mawk> velo is velocypede, the real name of bicyle
2020-05-12T20:54:02 < mawk> or velocipede maybe
2020-05-12T20:54:08 < antto> that's how it's called in .bg too
2020-05-12T20:54:09 < PaulFertser> Russian word sounds very similar
2020-05-12T20:54:13 < mawk> it means "walking fast" in latin
2020-05-12T20:54:28 < Steffanx> Russian never sounds similar :P
2020-05-12T20:54:37 < antto> latin is wrong, ur not really walking with that thang
2020-05-12T20:54:58 < Cracki> the first bicycles didn't have pedals
2020-05-12T20:55:00 < boddax> velocipede -> piede veloce -> fast feet
2020-05-12T20:55:08 < Cracki> you pushed forward with your feet

2020-05-12T20:55:45 < boddax> laughmachine
2020-05-12T20:55:59 < PaulFertser> So is English "push bike", that's wrong also because clip-in pedals allow you to do plenty of pulling too.
2020-05-12T20:56:00 < Steffanx> I do know the "benenwagen" mawk
2020-05-12T20:56:05 < mawk> the son of Napoleon III was nicknamed Vélocipède IV because he liked the bike so much
2020-05-12T20:56:18 < boddax> bifolk wagen
2020-05-12T20:56:25 < antto> the whole day i thought it's wednesday
2020-05-12T20:56:38 < Steffanx> Gooday thorn 
2020-05-12T20:56:53 < mawk> you just gained one day antto be happy
2020-05-12T20:56:54 < Thorn> evening Steffanx 
2020-05-12T20:57:05 < antto> "gain" >:(
2020-05-12T20:57:28 < antto> i don't think you understand the scale of this
2020-05-12T20:57:34 < mawk> y
2020-05-12T20:58:04 < Steffanx> So you wont be free on Ascension day mawk? Cant even take advantage of the Christiam background of zhe dutch?
2020-05-12T20:58:11 < Steffanx> *n
2020-05-12T20:58:26 < mawk> I'll do it at 22h before ascension, and if it goes wrong then I'll have the whole day to fix it
2020-05-12T20:58:30 < mawk> but I won't do it myself probably
2020-05-12T20:58:40 < mawk> yes I like taking advantage of them dirty christians
2020-05-12T20:58:40 < Steffanx> Yeah, no gain. 1 day more away from the weekend. So not a positive gain
2020-05-12T20:58:42 < boddax> like achilles from virgilius writer you know
2020-05-12T20:59:04 < mawk> with he undipped heel

2020-05-12T22:23:31 < zyp> power problem: let's say I have a 3.3V input rail and a 5V input rail, either or both may be present, if present I'd like to draw all power from the 3.3V input, I need to generate several output rails, including 3.3V
2020-05-12T22:23:47 < zyp> what's the most sensible way to do this?

2020-05-12T22:24:50 < Thorn> are other output rails < 3.3V?

2020-05-12T22:25:58 < jpa-> if 3.3V input is present, is it fine to just fet connect the input 3.3V to output 3.3V?
2020-05-12T22:26:05 < zyp> yes
2020-05-12T22:26:13 < qyx> oh wait
2020-05-12T22:26:42 < Thorn> there're boosts with passthrough mode but I'm not really sure about bucks
2020-05-12T22:26:46 < jpa-> sounds like a P-mosfet with source to the input 5V rail, and buck from the 5V rail to 3.3V rail could work

2020-05-12T23:44:03 < zyp> what would the opposite of clock recovery be called?
2020-05-12T23:45:46 < qyx> clock embedding?
2020-05-12T23:45:55 < qyx> self clocking magic
2020-05-12T23:46:48 < zyp> my usb receiver has a clock recovery module that takes the incoming signals, recovers the clock and outputs a bit stream
2020-05-12T23:47:19 < zyp> the usb transmitter has a corresponding module that takes a bit stream and outputs it at 12 Mb/s
2020-05-12T23:48:24 < zyp> everything else doesn't care about the data rate and is just timed by flow control on the streams
2020-05-12T23:49:32 < zyp> and I can't figure out what to call the module, so when I refactored the transmitter the other day it ended up just being called «output» since it's last in the pipeline, but I don't feel that is very descriptive
2020-05-12T23:53:52 < zyp> ClockEmbedder could work, but I feel that's not entirely correct
2020-05-12T23:54:35 < zyp> the input to the block is already bitstuffed and NRZI encoded, so it's not really embedding a clock like e.g. a manchester encoder would be, it's just clocking out the bits at the proper rate

2020-05-13T00:43:51 < Laurenceb> the onto-logic of amniotics does not suggest that all bodies of water are the same in terms of their being, but rather that bodies of water share a way of being because they are bodies of water.The amnion materializes a mode of relation being that is certainly transcorpeal - transitioning across and between bodies - but a kind of transit that also nurtures and facilitates other bodies.

2020-05-13T09:23:22 < jadew> and the answer was that they didn't receive it yet from elecrow...
2020-05-13T09:24:17 < jadew> the AWB was created on the 7th, after I asked about the status of the order

2020-05-13T15:51:27 < Steffanx> Nope
2020-05-13T15:51:54 < mawk> we can't get them here anyway
2020-05-13T15:51:58 < mawk> everytime I ask at the pharmacy, they say no
2020-05-13T15:52:04 < mawk> can't even find disinfectant
2020-05-13T15:52:25 < mawk> in france they have them in grocery stores now, you can buy boxes of 50 or 100, I asked my mother to send me some
2020-05-13T15:52:27 < Steffanx> My dad got quite a bit of it, so i steal it from him
2020-05-13T15:52:34 < mawk> since it will be mandatory to wear them in the train

2020-05-13T15:52:37 < mawk> a
2020-05-13T15:52:41 < Steffanx> I go by car :)
2020-05-13T15:52:45 < mawk> lol
2020-05-13T15:52:47 < mawk> I have no license
2020-05-13T15:52:52 < mawk> I bought isopropyl alcohol on amazon, 5L
2020-05-13T15:53:09 < mawk> but I also found a chinese shop with hidden bottles in a shelve in the back of the store, so I bought some there too
2020-05-13T15:53:17 < mawk> 1.5L bottles of IPA
2020-05-13T15:53:36 < mawk> but it's all a rip off
2020-05-13T15:53:59 < mawk> 15€/L, it's not precious ink, it's almost an industrial byproduct
2020-05-13T16:00:52 < kakimir> normal price is 3€/L for small quantities
2020-05-13T16:13:49 < mawk> yeah
2020-05-13T16:13:58 < mawk> I do 31% distilled water, put in a spray bottle
2020-05-13T16:14:08 < mawk> but it dries up too fast I think, but i can't add more water or it's less effective
2020-05-13T16:14:13 < mawk> maybe I need a gelifiant of some sort
2020-05-13T16:14:28 < mawk> but the industrial gelifiant is TMSO and it's very dangerous to handle, so I won't use that
2020-05-13T16:16:43 < Cracki> since the TP shortage is now over, you can make your own wetwipes with IPA and TP
2020-05-13T16:17:20 < Cracki> keeps the alcohol in contact with skin as long as you like
2020-05-13T16:17:48 < mawk> tp is too easy to tear, you need stronger paper
2020-05-13T16:17:52 < mawk> but yeah good idea
2020-05-13T16:17:56 < Cracki> from watching Drain Addict on yt I learned that wetwipes don't disintegrate like tp does so it is messy to handle
2020-05-13T16:18:19 < Cracki> kitchen roll or tissues for nose blowing maybe
2020-05-13T16:18:30 < mawk> yeah I have industrial kitchen roll
2020-05-13T16:18:45 < mawk> it doesn't tear easily
2020-05-13T16:19:27 < Cracki> I hope the TP and kitchen roll factories understand that average demand is constant and they get to run at half speed for the foreseeable future, while everyone wipes away their mountains of tp at home
2020-05-13T16:19:58 < Cracki> grocery store doesn't know where to put the stuff, they're overstocked now

2020-05-13T16:36:54 < catphish> how accurate are stm32 internal oscillators?
2020-05-13T16:37:25 < mawk> sometimes good enough for USB catphish 
2020-05-13T16:37:31 < mawk> on some chips
2020-05-13T16:37:34 < catphish> i just set up a timer with a 10s interval, it's running at 9.8s, i can't believe they're *that* bad
2020-05-13T16:38:13 < catphish> but i wanted to ask if a 2% error was possible before i debug my code
2020-05-13T16:38:48 < mawk> how do you measure ?
2020-05-13T16:40:08 < PaulFertser> catphish: if you're using LSI assuming it's 32.768 kHz then it would be very wrong of course, as it's about 38 kHz.
2020-05-13T16:40:13 < englishman> mawk, the ones that support crystalless usb have a clock recovery thingy and are especially made for that
2020-05-13T16:40:33 < mawk> yes
2020-05-13T16:40:38 < mawk> or use the usb frame start as clock
2020-05-13T16:40:42 < mawk> well, to recover the clock
2020-05-13T16:40:47 < catphish> it sends a packet, then sets a 10s timer to send another one, wireshark is showing the packets arriving at precise intervals of 9.82s intervals
2020-05-13T16:41:38 < englishman> catphish: for a reference, Xilinx internal oscillators have a tolerance of 50%

2020-05-13T16:42:07 < mawk> heat the board catphish , see if the duration changes
2020-05-13T16:45:56 < PaulFertser> catphish: is it a normal timer using HSI?
2020-05-13T16:46:41 < catphish> that's either MSI or HSI (i forget which) running the PLL on the F4 generating 180MHz
2020-05-13T16:47:10 < Cracki> put a finger on the chip. that should heat/cool already :>
2020-05-13T16:47:27 < Cracki> you can calibrate those things
2020-05-13T16:47:34 < catphish> it's already moderately warm, at that speed :)
2020-05-13T16:47:56 < Cracki> grep rm/ds for calibration value?
2020-05-13T16:48:27 < catphish> the datasheet claims 1% accuracy
2020-05-13T16:48:37 < Cracki> close enough :>
2020-05-13T16:49:30 < Cracki> it says to molest HSITRIM
2020-05-13T16:50:44 < Cracki> hsitrim step is 0.04 mhz (hsi 8 mhz says here)
2020-05-13T16:50:56 < catphish> it really should be more accurate than 2% at the temperature it's running at, but i suspect it's the oscillator and not my code at least

2020-05-13T17:04:48 < Laurenceb> internal is only good enough for usb with the trim thingy
2020-05-13T17:05:09 < Laurenceb> annoyingly it is a FLL not PLL, so it still drifts relative to the usb clock
2020-05-13T17:05:53 < Laurenceb> RTC with trim is crazy accurate, even with a crappy xtal, especially if you use the internal temp sensor to correct it
2020-05-13T17:06:14 < catphish> afaik internal is only good enough for USB on the specific chips that lock an internal lock to the incoming USB signal
2020-05-13T17:06:18 < Laurenceb> I was getting a few seconds every 3 months error
2020-05-13T17:06:24 < catphish> *lock an internal clock
2020-05-13T17:06:51 < Laurenceb> yeah but they dont *lock* they "align" as its an FLL
2020-05-13T17:07:00 < Cracki> what kinda correction do you need to do with temp sensor? is it linear or do you need some table?
2020-05-13T17:07:02 < Laurenceb> so there is still some annoying drift
2020-05-13T17:07:08 < Laurenceb> it was just linear
2020-05-13T17:07:16 < catphish> well it does a good enough job of it that it works
2020-05-13T17:07:34 < Laurenceb> good enough for +-1s/month in an office with +-15ppm xtal
2020-05-13T17:07:52 < Cracki> ah you had LSE
2020-05-13T17:07:57 < Laurenceb> yeah
2020-05-13T17:08:11 < Laurenceb> you can get grain of rice size 32khz xtals
2020-05-13T17:08:21 < Laurenceb> close ot 0603
2020-05-13T17:08:27 < Cracki> 15 ppm itself is 38s a month
2020-05-13T17:08:49 < Laurenceb> yeah I was surprised how well basic calibration worked
2020-05-13T17:08:50 < Cracki> so correction adds an order of magnitude. good to know
2020-05-13T17:09:02 < catphish> the usb auto-calibration is pretty cool
2020-05-13T17:09:19 < Laurenceb> its pretty cool for usb, useless for must things as its not pll
2020-05-13T17:09:22  * Laurenceb reee
2020-05-13T17:09:32 < Cracki> the temp sensor in my f3 only gives ~1K accuracy and it seems rather noisy too
2020-05-13T17:09:37 < Laurenceb> maybe it could be haxored with an interrupt and dither routine
2020-05-13T17:10:00 < Laurenceb> to make a pseudo fractional N PLL
2020-05-13T17:10:43 < Laurenceb> for babbyshake I used resampling to align
2020-05-13T17:11:08 < Laurenceb> as almost all mems sensors use crappy internal RC oscillator that would probably still be needed

2020-05-13T21:13:42 < Cracki> are there nozzles that have inside "knives" that cut into the filament, give larger surface for heat transfer?
2020-05-13T21:13:49 < bitmask> I think anet uses marlin with very few features enabled, but I have flashed it a number of times

2020-05-13T21:14:57 < PaulFertser> bitmask: I'm almost sure anet was based on repetier but what's very odd is that they have disabled thermal runaway protection thus leading to fires.
2020-05-13T21:15:21 < bitmask> oh ok, well yea I installed marlin on it right when I got it
2020-05-13T21:15:40 < bitmask> then about a year later I switched to klipper + octoprint
2020-05-13T21:15:58 < Cracki> the only 3d printer I have handson experience with, ultimaker 2, reaches its limits pretty fast. temp sensor is too far away from where the filament meets the nozzle, so you have to manually overcompensate for flow rate
2020-05-13T21:16:10 < Cracki> and some flow rates are just not possible

2020-05-13T21:17:28 < bitmask> PaulFertser the corexy I want (railcore II) won't fit in my lack table enclosure and is about twice as much.  I would love to have a non bed flinger but I dont have the space for it right now
2020-05-13T21:17:43 < englishman> oh, model 3 as well, but the qfp is smaller
2020-05-13T21:17:56 < PaulFertser> bitmask: but when you're building your own you can make it any size, right?
2020-05-13T21:18:12 < PaulFertser> And with same bed size corexy would be even more compact.

2020-05-13T23:17:58 < englishman> what backend would that be?
2020-05-13T23:18:01 < superbia> don't even bring the bsd keyword in the chat
2020-05-13T23:18:02 < englishman> the app store thingy?
2020-05-13T23:18:04 < superbia> i will leave the channel
2020-05-13T23:18:06 < ds2> englishman: what app are you using?
2020-05-13T23:18:06 < ds2> backend as in appstore
2020-05-13T23:18:13 < englishman> pebble app
2020-05-13T23:18:21 < englishman> i think it goes to the rebble catalogue
2020-05-13T23:18:26 < englishman> not that i use any apps tho
2020-05-13T23:18:32 < ds2> heh
2020-05-13T23:18:36 < Steffanx> got bsd'd superbia?
2020-05-13T23:18:45 < superbia> please 
2020-05-13T23:18:51 < englishman> superbia i am thinking of getting an omega speedmaster professional moonwatch, once this pebble dies
2020-05-13T23:18:53 < ds2> compromised with the Amazfit... no apps but otherwise has most of the pebble features
2020-05-13T23:19:15 < superbia> englishman: I also wanted it, but don't get it
2020-05-13T23:19:20 < englishman> i played the digging game but don't have any interest in any watch apps
2020-05-13T23:19:45 < englishman> why is that superb
2020-05-13T23:19:47 < Steffanx> Which one englishman? The $5k one?
2020-05-13T23:19:51 < Steffanx> isnt that a bit on the cheap side?
2020-05-13T23:19:58 < superbia> it's 3k new
2020-05-13T23:20:02 < englishman> it's just a swatch anyway
2020-05-13T23:20:18 < superbia> just the box it comes with costs 500 eur
2020-05-13T23:20:30 < Steffanx> Why do you need a box for a watch?
2020-05-13T23:21:41 < superbia> basically if you buy a speedmaster, you buy the plastic glass version (which is soft like chocolate), and it retains it's value, it's manual wind (you have to wind it every day), but that is not the issue with the speedmaster... The issue is that it basically has no water resistance, just like the fucking breitling navitimer.
2020-05-13T23:22:26 < englishman> it says 5 bar
2020-05-13T23:22:30 < superbia> it's bullshit
2020-05-13T23:23:01 < Steffanx> i wouldnt ever get a 3k watch. ill damage it on day one for sure.
2020-05-13T23:23:09 < superbia> let me try to explain
2020-05-13T23:23:18 < Steffanx> unless there suddenly would grow a money tree in the backyard, then i would probably.
2020-05-13T23:23:23 < englishman> i think ill just get a $50 swatch
2020-05-13T23:23:30 < englishman> with a metal band
2020-05-13T23:23:37 < superbia> you go shower yourself, or you are cooking, the steam from your skin penetrates like nothing
2020-05-13T23:23:41 < superbia> let me show you
2020-05-13T23:23:46 < superbia> https://omegaforums.net/data/attachments/61/61611-2a976ab4d2687891cd95bc13f949137b.jpg

2020-05-13T23:24:15 < Steffanx> Even my 30 euro casio watch didnt do that.
2020-05-13T23:24:37 < englishman> yeah what junk
2020-05-13T23:24:40 < englishman> no water on the moon i guess
2020-05-13T23:24:47 < superbia> this happens when you are on sun, or have warm skin
2020-05-13T23:24:51 < superbia> the moisture wants to go out
2020-05-13T23:25:16 < superbia> and as soon as you see fog inside, the first thing that will hapen is the lume-markers will go from white->amber
2020-05-13T23:25:31 < superbia> if you buy used watch, if you see non-snow-white lume, don't buy it
2020-05-13T23:25:42 < superbia> https://omegaforums.net/data/attachments/90/90139-6a9f9555237468eea17454abeecd5f5d.jpg
2020-05-13T23:25:45 < englishman> buy a used watch?
2020-05-13T23:25:54 < superbia> yea
2020-05-13T23:26:00 < superbia> people say shit like "patina"
2020-05-13T23:26:05 < superbia> niceley aged dial
2020-05-13T23:26:11 < superbia> (it's all water damage)
2020-05-13T23:26:22 < superbia> and you didn't even see the mechanism under the dial
2020-05-13T23:26:26 < englishman> when selling a used watch do you have to put the number of times you have jerked off with it?
2020-05-13T23:26:39 < superbia> do you want to know what to buy or not?
2020-05-13T23:26:49 < superbia> because I am not going to blabber about watches if you are not interested
2020-05-13T23:27:13 < englishman> the moonwatch interested me
2020-05-13T23:27:26 < superbia> and plexi (crystal) is like chocolate
2020-05-13T23:27:30 < englishman> i would like one with a chrony
2020-05-13T23:27:42 < englishman> maybe the feature i use most on the pebble
2020-05-13T23:27:49 < superbia> chronograph ?
2020-05-13T23:27:52 < englishman> yes
2020-05-13T23:27:52 < superbia> what do you time ?
2020-05-13T23:27:58 < englishman> everything
2020-05-13T23:28:05 < superbia> do you time stuff longer than 1 hour ?
2020-05-13T23:28:14 < englishman> not often
2020-05-13T23:28:27 < superbia> then you can do everything with a dive-bezel
2020-05-13T23:28:35 < superbia> do you know how to operate it ?
2020-05-13T23:28:48 < englishman> sure, but i don't want to
2020-05-13T23:29:01 < englishman> i did that enough while flying
2020-05-13T23:29:21 < superbia> so you want a propper chronograph ?
2020-05-13T23:29:27 < englishman> yes
2020-05-13T23:29:47 < superbia> size, weight, material, complications, price ?
2020-05-13T23:30:23 < englishman> like i said, the moonwatch is interesting, steel bracelet, good size not too thick
2020-05-13T23:30:56 < englishman> https://shop.swatch.com/en_ca/watches/irony/chrono/night-flight-yvs444g.html
2020-05-13T23:31:09 < Steffanx> Too cheap.
2020-05-13T23:31:44 < superbia> does it have to be manual?
2020-05-13T23:31:57 < englishman> that swatch is battery quartz
2020-05-13T23:31:58 < englishman> so no
2020-05-13T23:32:10 < superbia> do you care about resell value ?
2020-05-13T23:32:25 < englishman> i didn't even know that there were people out there that bought used watches
2020-05-13T23:32:28 < englishman> sounds gross tbh
2020-05-13T23:32:41 < superbia> it's a big deal
2020-05-13T23:32:51 < superbia> do you know how africa gas station operates ?
2020-05-13T23:33:15 < superbia> people buy all gas (truck comes once a month) and they resell gas near the gas station in little plastic bottles for more $$
2020-05-13T23:33:21 < Steffanx> Whats wrong with a digital watch with a proper timer/stopwatch? :D
2020-05-13T23:33:38 < englishman> does casio still make a calculator watch?
2020-05-13T23:33:49 < superbia> Steffanx: rolex daytona MSRP is 13k, on second hand as new it costs 26k
2020-05-13T23:33:52 < Steffanx> i think so englishman
2020-05-13T23:34:01 < superbia> and you can't buy daytona for MSRP because it's sold out and waitlisted
2020-05-13T23:34:28 < Steffanx> Thanks will consider it.
2020-05-13T23:34:37 < superbia> the "gray dealers" make about 10k reselling new watches as new on the second hand market
2020-05-13T23:35:09 < superbia> basically if you buy the right watch, it won't loose it's value
2020-05-13T23:35:18 < superbia> it's like traveling with X amount of money on your wrist
2020-05-13T23:35:30 < superbia> you can pawn it anytime, anywhere for cash

2020-05-13T23:37:30 < superbia> planet ocean is a "diver" which means very high water resistance... aka very thick
2020-05-13T23:37:34 < superbia> thick boy
2020-05-13T23:39:38 < englishman> i had an automatic seiko
2020-05-13T23:39:41 < englishman> it died after a few years
2020-05-13T23:39:48 < englishman> was more expensive to fix than to get a new one
2020-05-13T23:40:21 < bitmask> my grandfather gave me a seiko but I dont wear watches, I'm sure its not a very expensive one
2020-05-13T23:40:46 < bitmask> he bought it for himself but decided it was too fancy hah

2020-05-13T23:41:54 < superbia> bitmask: seiko was once uber brand
2020-05-13T23:42:09 < superbia> better than omega and rolex
2020-05-13T23:42:23 < superbia> you never see vintage seiko with amber lume, but all swiss watches have amber lume (water damage)
2020-05-13T23:42:26 < bitmask> I knew it was high up, didnt know that high though
2020-05-13T23:42:30 < superbia> japanese knew how to seal their watches abainst water
2020-05-13T23:42:45 < bitmask> I think i have a pic of mine on imgur one sec

2020-05-13T23:43:33 < englishman> that works
2020-05-13T23:43:40 < englishman> maybe ill get a quartz seiko
2020-05-13T23:43:46 < englishman> or that swatch
2020-05-13T23:44:00 < englishman> nice
2020-05-13T23:44:10 < englishman> yeah omega got expensive only recently right
2020-05-13T23:44:15 < superbia> bitmask: 3.6 rotgens, not good, not bad
2020-05-13T23:44:32 < superbia> englishman: if you can, go up to 8k and buy a submariner no-date
2020-05-13T23:44:47 < superbia> brand new, in store, you wont loose a cent on it
2020-05-13T23:46:29 < englishman> the little crown protectors are a nice touch
2020-05-13T23:46:41 < superbia> where ?
2020-05-13T23:46:46 < englishman> on the submariner
2020-05-13T23:46:59 < englishman> so you dont bend it off when you smash it against stuff
2020-05-13T23:47:01 < superbia> it's the original james bond watch
2020-05-13T23:47:30 < englishman> that looks good
2020-05-13T23:47:43 < superbia> but it could be waitlisted, depending where you are in the world
2020-05-13T23:48:00 < superbia> if you come to me in switzerland, I know some people that work in retail, you could get one asap
2020-05-13T23:48:15 < englishman> the pebble works fine for now
2020-05-13T23:48:16 < superbia> just don't buy on second hand or gray market
2020-05-13T23:48:23 < superbia> think of it as investment
2020-05-13T23:48:27 < englishman> but the last one didn't hold a charge anymore after 3 years
2020-05-13T23:48:36 < superbia> you worked too hard to wear a shitty watch
2020-05-13T23:48:43 < englishman> i dont work very hard
2020-05-13T23:48:55 < superbia> well you are english
2020-05-13T23:49:00 < superbia> but I assume you did
2020-05-13T23:49:01 < englishman> i am not
2020-05-13T23:49:25 < superbia> did you check the zenith el primero?
2020-05-13T23:49:28 < superbia> or the sinn chronographs ?
2020-05-13T23:49:46 < superbia> sinn makes instrument chronographs for the german police and army
2020-05-13T23:50:03 < sync> why would you wear a watch when you have one in your pocket anyway
2020-05-13T23:50:47 < englishman> phone is more accurate than any mechanical watch as well
2020-05-13T23:51:00 < superbia> do you really need sub-second precision
2020-05-13T23:51:03 < englishman> i guess that is also a good feature of the pebble
2020-05-13T23:51:26 < superbia> yea, if you want something more special, and live near central europe you can check this vendor http://www.habring2.com/index.php/en/collection/chrono-felix
2020-05-13T23:51:41 < superbia> there's a few "independant" vendors all around the world, depending on your location
2020-05-13T23:52:49 < superbia> if you are really serious about some watch you can dm me and we can talk
2020-05-13T23:53:02 < englishman> not sure i want to be serious about a watch
2020-05-13T23:53:14 < superbia> there's no point in blabbering here when retards like sync wonder why you wouldn't want to touch your phone to check the time with corona on your fingertips
2020-05-13T23:54:31 < sync> well, then I have cortana on my watch
2020-05-13T23:54:48 < superbia> maybe on your jacket sleeve
2020-05-13T23:54:53 < sync> but the only watch I wear is my altimeter
2020-05-13T23:55:11 < superbia> if you touch your watch to read the time you are doing it wrong
2020-05-13T23:56:10 < superbia> if your lunix date widget goes to dong, you can just glance your wristwatch
2020-05-13T23:56:29 < superbia> also when signing stuff... no need to fiddle with lunix date widgets and check phone
2020-05-13T23:56:54 < sync> only to find out that the watch has stopped working a few days ago
2020-05-13T23:57:04 < superbia> it's automatic, it self winds
2020-05-13T23:57:12 < superbia> power reserve is like 72hours on modern watches

2020-05-14T00:14:20 < qyx> zyp: did you do usb host on stm32?
2020-05-14T00:16:38 < zyp> I've looked a bit into how to do it, but I haven't done it
2020-05-14T00:17:22 < qyx> https://community.st.com/s/question/0D50X0000BZHqAo/writing-a-usb-host-for-a-composite-usb-device-quectel-bg96-modem
2020-05-14T00:17:30 < qyx> this is exactly what I will be facing
2020-05-14T00:18:00 < qyx> the only difference is the modem (ec21)
2020-05-14T00:18:53 < zyp> with the ST provided stack?
2020-05-14T00:19:16 < qyx> no, I haven't decided yet
2020-05-14T00:19:35 -!- Jak_o_Shadows [~Jak@unaffiliated/jak-o-shadows/x-0479135] has joined ##stm32
2020-05-14T00:21:43 < zyp> I think data pipes would act more or less the same from the host and device perspectives, the difference is normally that the host needs to deal with enumeration and shit
2020-05-14T00:22:35 < zyp> i.e. the device provides descriptors that tells what it is and which endpoints it's using for what, the host then has to find an appropriate driver and bind it to those endpoints
2020-05-14T00:22:47 < zyp> once that's done the rest should be more or less the same
2020-05-14T00:23:04 < qyx> hm, probably I could omit all this
2020-05-14T00:23:13 < qyx> because the modem will be hardwired
2020-05-14T00:23:14 < zyp> and if you're only gonna support one device, you could even skip the entire descriptor parsing and just hardcode it
2020-05-14T00:23:24 < qyx> and I will know the exact model (or i can easily check)
2020-05-14T00:23:30 < qyx> yeah
2020-05-14T00:24:04 < zyp> so if you got a bit of usb experience, it shouldn't be too hard to get going from scratch
2020-05-14T00:24:15 < qyx> I have about zero usb experience
2020-05-14T00:24:51 < qyx> for now I have that Omega2 board with miniPCIe, I am using mikrotik LTE cards with it
2020-05-14T00:25:21 < qyx> in the future I will want to do a stm32 version of such LTE card
2020-05-14T00:25:24 < zyp> my guess is that I would be able to get basic usb host comms going in an afternoon, but since I haven't actually done it, that's just a guess
2020-05-14T00:25:26 < qyx> I'll ask then :P
2020-05-14T00:25:46 < zyp> :p
2020-05-14T00:26:41 < superbia> night pros
2020-05-14T00:28:30 < zyp> hmm, I should probably do some usb host experiments on stm32
2020-05-14T00:28:52 < qyx> it supports 921600 baud on the main uart
2020-05-14T00:28:55 < qyx> probably enough
2020-05-14T00:29:02 < qyx> meh

2020-05-14T00:29:33 < zyp> eventually I'd like to add host support to the usb core I'm writing now, and before I do that it's probably a good idea to already have some experience with the software side of it
2020-05-14T00:30:35 < qyx> see, the important part is to motivate someone with the right knowledge
2020-05-14T00:30:57 < zyp> ;)
2020-05-14T00:31:26 < qyx> so
2020-05-14T00:31:32 < qyx> blogging PCIe obsession:
2020-05-14T00:32:15 < qyx> today I found out the SIM7000E module for one of the daughter cards is unobtainable, at least in the EU
2020-05-14T00:32:44 < qyx> made some calls with salesmen, I'll probably go with quacktel instead
2020-05-14T00:32:55 < zyp> looked over the OTG_FS/HS chapters in RM0090 now, shit's not too different from device mode
2020-05-14T00:32:57 < qyx> BC95 looks ok, MC66 too
2020-05-14T00:33:09 < qyx> *BC66
2020-05-14T00:33:10 < specing> qyx: doesen't quactel run embedded Linux that you cannot change?
2020-05-14T00:33:32 < qyx> I am not into changing anything running on the module itself
2020-05-14T00:34:13 < zyp> since you're host, you're controlling reset instead of monitoring for it and you're monitoring attach (DP pullup) instead of controlling it, and once through that the hardware negotiates speed for you, just like in device mode
2020-05-14T00:34:31 < qyx> so I have to redo the card to accomodate the new module :S
2020-05-14T00:34:46 < qyx> zyp: sounds ~easy
2020-05-14T00:35:09 < zyp> and once that's done you can start sending and receiving packets, at which point the difference is that you don't have endpoint buffers, you have host channel buffers
2020-05-14T00:46:00 < Thorn> you will need to implement enumeration, class driver dispatch, hub control (with hubs plugged into hubs), interrupt EP polling, ...
2020-05-14T00:47:43 < zyp> not if you're only ever gonna support one known device
2020-05-14T00:48:03 < zyp> but yeah

2020-05-14T00:58:49 < Steffanx> @ mawk
2020-05-14T00:59:31 < Steffanx> But that should be in the papers you signed ofcourse
2020-05-14T01:00:45 < Steffanx> Its usually like 8%/month
2020-05-14T01:00:50 < Steffanx> And its mandatory

2020-05-14T05:41:22 < Laurenceb> anyone here any good with lunix?
2020-05-14T05:41:30 < Laurenceb> suspend is failing intermittently
2020-05-14T05:41:38 < Laurenceb> it used to fail about 1/1000 times
2020-05-14T05:41:49 < Laurenceb> now it fails about 1/3 so its basically unusable
2020-05-14T05:41:56 < Laurenceb> any ideas how to debug this?
2020-05-14T05:42:35 < Laurenceb> symptoms are: pc looks like its going into suspend, then in final stages it stalls with fan at 100% for about 5 minutes then turns off completely
2020-05-14T05:42:50 < Laurenceb> cant find the logs :( 
2020-05-14T05:42:59 < Laurenceb> any idea where the error log might be hiding?
2020-05-14T05:45:01 < Thorn> looks too verbose and detailed for yet another Laurenceb copypasta. could it be an actual question?
2020-05-14T05:45:17 < Laurenceb> lol
2020-05-14T05:45:44 < Laurenceb> tl;dr where are the lunix error logs?
2020-05-14T05:47:05 < Thorn> usually /var/log
2020-05-14T05:48:14 < Thorn> but if it crashes you may want to try https://ubuntu.com/server/docs/kernel-crash-dump
2020-05-14T05:48:22 < Laurenceb> aha there is a pm-suspend log
2020-05-14T05:48:38 < Laurenceb> hmm maybe its running out of memory due to chrome getting extra stupid
2020-05-14T05:49:12 < Laurenceb> wtf

2020-05-14T05:49:28 < Laurenceb> no sign of failure in the log
2020-05-14T05:50:57 < Laurenceb> aha it failed between >performing suspend and >Finished

2020-05-14T12:43:45 < mawk> stop being so materialistic PaulFertser 
2020-05-14T12:43:49 < mawk> you don't need anything
2020-05-14T12:44:13 < mawk> you need to delest yourself from your material possessions, let nothing affect your inner zen
2020-05-14T12:44:22 < mawk> and only then you can reach nirvana
2020-05-14T12:44:46 < mawk> I'll give you my address for the delesting part
2020-05-14T12:44:52 < PaulFertser> mawk: I do not but my brother needs a thunderbolt3 addon card for their knew sound recording studio workstation.
2020-05-14T12:46:38 < PaulFertser> (and I have no idea what delesting means)
2020-05-14T12:48:18 < mawk> throwing away
2020-05-14T12:48:28 < mawk> usually I take the french word, englishify it and it works
2020-05-14T12:48:59 < mawk> the lest is the heavy sand sacks you have in hot air balloons to make it heavier, and you can throw them over board ("delest") to make it lighter in case something goes wrong
2020-05-14T12:49:22 < karlp> ballast is the english word for the sacks and similar in boats/ships
2020-05-14T12:49:27 < mawk> ah I see
2020-05-14T12:49:35 < mawk> "deballast yourself" doesn't sound as nice
2020-05-14T12:49:38 < karlp> but you don't use deballast for that
2020-05-14T12:50:07 < karlp> there's a few phrases for the "kill your things" style
2020-05-14T12:50:44 < karlp> I can't think of any off the top of my head that are a clean antonym though
2020-05-14T12:52:36 < PaulFertser> "dump your ballast" probably?

2020-05-14T12:53:31 < karlp> that's the phrase for ballooning, or getting a boat off a reef, yes
2020-05-14T12:53:42 < karlp> but I'v never really heard of it used in the contex of possesions
2020-05-14T12:53:59 < PaulFertser> Probably you're not talking to hippies often enough ;)
2020-05-14T12:54:01 < karlp> ballast on humans is (IME) normally referring to bad partners or jobs
2020-05-14T12:54:28 < karlp> PaulFertser: possibly, but I just don't think ballast is used
2020-05-14T12:54:43 < PaulFertser> Or to anarchists like those saying https://en.wikipedia.org/wiki/Property_is_theft!
2020-05-14T12:54:44 < karlp> minimize, downsize your posessions, declutter, blah
2020-05-14T12:55:25 < PaulFertser> declutter sounds like something hipsters would be coaching each other during "retreats"
2020-05-14T12:56:57 < karlp> well, in mawk's original sentence, "you need to delest yourself from your material possessions, let nothing affect your inner zen" you should/could just do s/delest/free/
2020-05-14T12:59:01 < PaulFertser> karlp: have you seen anybody adding gd32v103 to libopencm3?
2020-05-14T12:59:38 < karlp> I said it would have to be done very very well, given that it'
2020-05-14T12:59:40 < karlp> s another toolchain
2020-05-14T12:59:58 < karlp> and I _generally_ wass't super interested in it,
2020-05-14T13:00:06 < karlp> even though I know the periphs are the "same"
2020-05-14T13:00:34 < karlp> it's not like there's some single awesome api anyway
2020-05-14T13:00:54 < karlp> but, prove me wrong? :)
2020-05-14T13:01:08 < PaulFertser> I do not have a board else I'd try doing that I guess.
2020-05-14T13:01:16 < PaulFertser> Just for the kicks.
2020-05-14T13:01:26 < karlp> make a libactuallyopenmicro and make it bsd2/apache2/mit/isc and find a niche?
2020-05-14T13:01:54  * karlp shrugs
2020-05-14T13:02:40 < PaulFertser> I just thought it would make sense given the peripherals are supposedly the same and hence the API should be the same.
2020-05-14T13:02:53 < PaulFertser> And most of the peripherals code can be reused.
2020-05-14T13:03:08 < karlp> I do understand that :)
2020-05-14T13:03:32 < karlp> it's already clunky with gd32f103 being ~same but not, and trying to share across families.
2020-05-14T13:03:55 < karlp> the different toolchain is a much harder problem to make neat.
2020-05-14T13:04:19 < PaulFertser> Indeed
2020-05-14T13:04:31 < karlp> I'm only gardening in locm3, I'm not doing any landscape architecture, fuck that on lgpl,
2020-05-14T13:04:55 < PaulFertser> Is LGPL harmful?
2020-05-14T13:05:09 < zyp> I'm planning to add gd32v to laks, just to have a more stable riscv reference in addition to the fpga stuff
2020-05-14T13:05:22 < karlp> PaulFertser: yes?
2020-05-14T13:05:40 < karlp> I mean, it's just ok enogh that I'll use it, but never again.
2020-05-14T13:05:53 < PaulFertser> karlp: what would you prefer, BSD?
2020-05-14T13:06:55 < karlp> "make it bsd2/apache2/mit/isc"
2020-05-14T13:07:04 < karlp> something actually free
2020-05-14T13:07:20 < PaulFertser> I thought LGPL is the best for the libraries since it allows to not disclose "the meat" but still makes it nice to the community by sharing the modifications to the library itself.
2020-05-14T13:07:37 < karlp> PaulFertser: sure, for libraries on dynlinked systems
2020-05-14T13:07:49 < karlp> but the "provide a makefile and some .o's" is fucking tedious bullshit
2020-05-14T13:08:12 < karlp> it's a library, except not really.
2020-05-14T13:08:16 < PaulFertser> karlp: why? Other than the fact that libraries also include inline functions, macros etc...
2020-05-14T13:08:47 < Thorn> zyp I've got a coroutine example running with co_await https://paste.jvnv.net/view/CWIRE
2020-05-14T13:09:04 < karlp> if you can't see how the providing relinking support for lgpl compliance is more work than bsd/mit/isc, then I can't help you :)
2020-05-14T13:09:54 < specing> you could also do GPL + commercial dual licensing
2020-05-14T13:10:00 < karlp> specing: hahahaha
2020-05-14T13:10:02 < PaulFertser> karlp: I'd be happy to always distribute full sources.
2020-05-14T13:10:21 < karlp> PaulFertser: then just make the project gpl, you'll restrit yourself to people who are ok with that.
2020-05-14T13:10:33 < specing> karlp: why hahahaha?
2020-05-14T13:10:45 < PaulFertser> Same logic applies to lgpl, it's restricted to people who are ok with that.
2020-05-14T13:10:46 < karlp> specing:need to have control of all copyright holders to try that sort of thing, ie fine for a corporate developed thing
2020-05-14T13:10:58 < karlp> PaulFertser: yeah, except it's like a shitty halfway.
2020-05-14T13:10:59 < specing> karlp: indeed
2020-05-14T13:11:11 < specing> karlp: that kind of projects have CLAs
2020-05-14T13:11:12 < PaulFertser> karlp: all-or-nothing ftw :)
2020-05-14T13:11:25 < karlp> PaulFertser: sure, and I want _free_ not obligations

2020-05-14T13:16:38 < PaulFertser> Please clarify
2020-05-14T13:22:17 < zyp> Thorn, interesting
2020-05-14T13:23:53 < karlp> PaulFertser: "buy cheap unspecced junk from china, complain about specs" :)

2020-05-14T13:26:03 < zyp> karlp, supporting other toolchains in laks was almost surprisingly easy, I just added a select_riscv() next to the select_arm() function in the build rules: https://paste.jvnv.net/view/A9Uld
2020-05-14T13:26:50 < karlp> zyp: yes, your scons build is quite a different setup though
2020-05-14T13:27:06 < mawk> so you played with riscv zyp 
2020-05-14T13:27:13 < zyp> karlp, yes, that's the point, it's better :)
2020-05-14T13:27:37 < karlp> and like I said, I'm not sayign no, but _I'm_ not doing the landscape architecture to overhaul it all for this
2020-05-14T13:27:41 < zyp> mawk, yes?
2020-05-14T13:28:26 < Thorn> zyp https://paste.jvnv.net/view/YRj5A
2020-05-14T13:29:29 < zyp> Thorn, looks neat
2020-05-14T13:30:41 < Thorn> a shit ton of boilerplate even for such a minimal example
2020-05-14T13:31:08 < Thorn> https://github.com/lewissbaker/cppcoro is actually scary to read
2020-05-14T13:39:05 < zyp> the important thing isn't the amount of boilerplate behind the scenes, the important thing is how neat the resuling code ends up being
2020-05-14T13:41:57 < karlp> well, thorn's example so far didn't look neat at all to me :)
2020-05-14T13:42:13 < Thorn> user code should look better than a freertos task but without a task
2020-05-14T13:53:07 < zyp> karlp, by resulting code, I mean lines 119-141
2020-05-14T13:53:22 < zyp> the stuff before is boilerplate the user shouldn't need to see
2020-05-14T13:55:58 < karlp> ok, that's better.
2020-05-14T13:56:27 < karlp> but thorn still had to,
2020-05-14T13:56:50 < karlp> so it's "coroutines might be nice, one day, but they're still piles of everything everyone laughs at c++ for" until then?
2020-05-14T13:58:47 < zyp> to me it looks more like «now the pieces are in place so you can start making coroutine-based frameworks» and Thorn started on his own
2020-05-14T13:59:06 < zyp> and that cppcoro thing looks like another
2020-05-14T13:59:11 < Thorn> pretty much this

2020-05-14T16:33:23 < Laurenceb> probably not fixed :(
2020-05-14T16:33:50 < Laurenceb> it alternates between taking 5s to suspend and ~35s
2020-05-14T16:33:58 < Laurenceb> thats probably not a good sign
2020-05-14T16:34:36 < dongs> you could also just install win10

2020-05-14T16:37:53 < Laurenceb> the time to suspend should not alternate like this

2020-05-14T16:41:09 < dongs> cuz he installed lunix on it
2020-05-14T16:41:14 < dongs> i wouldnt support anything that shit touches either
2020-05-14T16:41:29 < dongs> i remember in like 1995 or something there were some toshiba laptops that would burn out the lcd because of lunix
2020-05-14T16:41:46 < dongs> the opensores video driver would crash (X) and LCD would become super white
2020-05-14T16:42:04 < specing> you mean they were badly made?

2020-05-14T16:44:28 < Laurenceb> so useful /s
2020-05-14T16:44:47 < mawk> so Laurenceb 
2020-05-14T16:44:50 < mawk> just enable verbose mode
2020-05-14T16:44:58 < mawk> and up the log level
2020-05-14T16:45:13 < Laurenceb> does that require a kernel flag?
2020-05-14T16:45:25 < mawk> just set it when you boot
2020-05-14T16:45:34 < mawk> in grub before the 5s delay you can hit E to edit the boot command line
2020-05-14T16:45:47 < mawk> remove quiet, add verbose, and add a good loglevel
2020-05-14T16:45:58 < mawk> then ctrl-x to boot that
2020-05-14T16:46:30 < Laurenceb> loglevel is a number after verbose?
2020-05-14T16:46:55 < mawk> no
2020-05-14T16:47:14 < mawk> verbose loglevel=8
2020-05-14T16:47:16 < mawk> like this
2020-05-14T16:47:21 < mawk> but it spits out a lot of stuff
2020-05-14T16:47:33 < mawk> maybe just loglevel 7 to have info messages
2020-05-14T16:47:58 < Laurenceb> ok

2020-05-14T16:55:49 < karlp> got some ideas....
2020-05-14T16:55:49 < mawk> there are still things to try
2020-05-14T16:56:00 < mawk> for instance if you tell the bios you're running linux, special code can run
2020-05-14T16:56:12 < karlp> "can" doesn't mean it will :)
2020-05-14T16:56:18 < mawk> acpi_osi=! acpi_osi=Linux
2020-05-14T16:56:19 < karlp> but yeah, sure, if you want to try
2020-05-14T16:56:23 < mawk> it does on my computer
2020-05-14T16:56:27 < mawk> it fixes the RGB keyboard
2020-05-14T16:56:35 < Laurenceb> >RGB keyboard
2020-05-14T16:56:35 < mawk> and a suspend issue in which the keyboard doesn't respond when coming out of suspedn

2020-05-14T16:56:38 < mawk> lol
2020-05-14T16:56:43 < mawk> it was just 20€ more or something
2020-05-14T16:56:54 < Laurenceb> hmm my logs arnt that much more useful
2020-05-14T16:57:01 < mawk> yeah lots of crap
2020-05-14T16:57:12 < Laurenceb> just tried a few suspend resume cycles, same weird timing glitches
2020-05-14T16:57:17 < mawk> ask linus
2020-05-14T16:57:24 < Laurenceb> lol
2020-05-14T16:57:31 < mawk> the perfect way to do it is to send a botched patch vaguely related to suspend
2020-05-14T16:57:36 < mawk> describe your issue in the patch message
2020-05-14T16:57:40 < mawk> then he will fix it for you
2020-05-14T16:57:42 < Laurenceb> heh
2020-05-14T16:58:11 < Laurenceb> which logfile should I take a look at?

2020-05-14T16:58:22 < mawk> it's the kernel log
2020-05-14T16:59:02 < Steffanx> Such materialism mawk.. rgb kb for $20
2020-05-14T16:59:14 < mawk> lol
2020-05-14T16:59:17 < Laurenceb> hmm ok I see some more suspend related stuff now
2020-05-14T16:59:18 < mawk> I can code in the dark now
2020-05-14T17:01:22 < Steffanx> Did you know a corona fine can get you a criminal record mawk?
2020-05-14T17:01:31 < Laurenceb> ok wut

2020-05-14T17:01:37 < mawk> oh nice Steffanx 
2020-05-14T17:01:50 < mawk> but I'm a good mawk I wear a mask and I go shopping alone
2020-05-14T17:01:57 < Laurenceb> ^10 second delay right there
2020-05-14T17:01:58 < Steffanx> Good good
2020-05-14T17:02:12 < Steffanx> You dont send your gf to go shopping? :o
2020-05-14T17:02:21 < mawk> yes too Steffanx 
2020-05-14T17:02:57 < mawk> so that narrows down the issue I guess Laurenceb 
2020-05-14T17:03:26 < Laurenceb> I'll paste it all
2020-05-14T17:04:14 < Steffanx> Here?

2020-05-14T17:06:00 < mawk> this timeouts, then tries again
2020-05-14T17:06:02 < mawk> then succeeds
2020-05-14T17:06:32 < Laurenceb> ah
2020-05-14T17:06:45 < mawk> I guess
2020-05-14T17:06:46 < Laurenceb> presumably multiple timeouts lead to the failures
2020-05-14T17:06:48 < mawk> because it shows up twice
2020-05-14T17:06:50 < mawk> yeah
2020-05-14T17:07:04 < mawk> how's the system load ? is it a realtime kernel ?
2020-05-14T17:07:17 < Laurenceb> nah its not realtime kernel
2020-05-14T17:07:34 < Laurenceb> it has low ram, could that be trying to run from swap?
2020-05-14T17:07:57 < Laurenceb> hmm hdd is already down by that point
2020-05-14T17:08:03 < mawk> I'm not aware that anything is put in swap during suspend, or is it hibernation we're discussing ?
2020-05-14T17:08:14 < Laurenceb> no its suspend
2020-05-14T17:08:27 < Laurenceb> >  223.468247] sd 0:0:0:0: [sda] Stopping disk
2020-05-14T17:08:32 < mawk> maybe stuff are flushed from ram to disk during that time, because the disk is stopped
2020-05-14T17:08:33 < Laurenceb> so HDD is already down
2020-05-14T17:08:34 < mawk> yeah
2020-05-14T17:09:07 < Laurenceb> I'll google it, at least it narrows down the issue

2020-05-14T17:27:25 < Laurenceb> damn
2020-05-14T17:28:08 < Laurenceb> maybe power management is screwed up
2020-05-14T17:29:15 < mawk> hack your bios Laurenceb 
2020-05-14T17:29:19 < mawk> then you can select things like this
2020-05-14T17:29:20 < Laurenceb> and cpu gets screwed up
2020-05-14T17:29:33 < Laurenceb> there is a newer bios available but its a pain to install
2020-05-14T17:29:49 < mawk> you should try it I guess
2020-05-14T17:30:05 < Laurenceb> I'll try your acpi_osi=! acpi_osi=Linux thing first as its easier
2020-05-14T17:30:10 < mawk> lol
2020-05-14T17:30:19 < mawk> that's if the motherboard is linux-friendly
2020-05-14T17:30:27 < Laurenceb> hmm
2020-05-14T17:30:33 < mawk> mine is H2O Bios, some chinesium thing, it supports linux
2020-05-14T17:30:35 < Laurenceb> I smell burning from the motherboard
2020-05-14T17:30:38 < mawk> lol
2020-05-14T17:30:40 < mawk> not good
2020-05-14T17:31:04 < Laurenceb> maybe there is a literal capacitor failure
2020-05-14T17:31:22 < strata> it's a 10 year old computer, Laurenceb.
2020-05-14T17:31:39 < Laurenceb> ikr
2020-05-14T17:31:53 < Laurenceb> >lunix invented "halt and catch fire"
2020-05-14T17:32:08 < mawk> yeah
2020-05-14T17:32:12 < mawk> well unix too, right
2020-05-14T17:32:22 < mawk> instead of trying to recover a borked system, you panic
2020-05-14T17:32:28 < mawk> that simplifies a whole lot the kernel code
2020-05-14T17:33:12 < Laurenceb> I think I should rip this thing down and look for hardware failures
2020-05-14T17:33:24 < mawk> maybe
2020-05-14T17:33:28 < mawk> don't damage cables
2020-05-14T17:33:40 < Laurenceb> maybe some busted caps are causing power supply issues
2020-05-14T17:34:26 < Laurenceb> anyway I'll also try that acpi thingy
2020-05-14T17:34:44 < Laurenceb> acpi_osi=Linux   ??
2020-05-14T17:34:50 < Laurenceb> or  =!     ??
2020-05-14T17:34:53 < mawk> both
2020-05-14T17:35:02 < Laurenceb> ok now I'm confused
2020-05-14T17:35:02 < mawk> acpi_osi=! acpi_osi=Linux
2020-05-14T17:35:08 < mawk> acpi_osi=! clears the list 
2020-05-14T17:35:13 < mawk> then acpi_osi=Linux adds Linux to it
2020-05-14T17:35:15 < Laurenceb> ok now I get it

2020-05-14T18:53:40 < Laurenceb> the demiurge!!
2020-05-14T19:07:58 < karlp> man, this little blade server here I wanted to upgrade and repurpose, had 2x300gig and 2x600gig drives
2020-05-14T19:08:04 < karlp> thought it might be nicely redundant or something.
2020-05-14T19:08:11 < karlp> nope. small boot partition on one disk,
2020-05-14T19:08:23 < karlp> all the rest is just dumped into a single big LVM blob called "root"
2020-05-14T19:10:19 < fenugrec> high performance JBOD
2020-05-14T19:14:20 < karlp> not entirely sure how happy I am with that, these are kinda old 
2020-05-14T19:15:29 < oz4ga> you could build a nice raid-z2 zfs w. 4 disks if you upgrade the disks 4T's anren't that expensive
2020-05-14T19:19:54 < qyx> karlp: 2.5"?
2020-05-14T19:21:05 < karlp> yeah
2020-05-14T19:21:45 < karlp> oz4ga: sure, I guess, was more thinking of just updating what is has now
2020-05-14T19:22:06 < karlp> it was running a shit old centos as a kvm server, but it was massively outdated, so I was going to rebuild it.

2020-05-14T19:25:11 < karlp> now that I know they're all independent though, I'm more inclined to put this 256gb ssd in it from my old laptop and let that be one of the storage options
2020-05-14T19:26:14 < karlp> not going to be able to set up zfs in the installer am I?
2020-05-14T19:28:02 < oz4ga> I have no idea of what various Linux distros offer when i comes to zfs. I'm with FreeBSD. I thought / hoped Linux had in integrated in the installers by now

2020-05-14T20:27:24 < Laurenceb> its ten years old and only down ~25% in capacity
2020-05-14T20:27:37 < Laurenceb> not bad, but it was stored at ~60% charge in a fridge
2020-05-14T20:27:57 < Laurenceb> gained a few percent since I last used it 5 years ago
2020-05-14T20:28:06 < BrainDamage> battery tech did switch to chemistries that are less energy dense but way more durable wrt shelf life
2020-05-14T20:28:38 < BrainDamage> my laptop's battery lost 10% capacity, and I've always left it in
2020-05-14T20:28:49 < Laurenceb> interesting
2020-05-14T20:28:52 < BrainDamage> so it went through a lot of thermal sttress

2020-05-15T00:52:12 < Laurenceb> >a standalone tool just to "fix" the bug
2020-05-15T00:52:21 < qyx> is it poettering's fault?
2020-05-15T00:52:35 < Ultrasauce> that goes without saying
2020-05-15T00:53:25 < Laurenceb> looks like the system going down is related to ram use at suspend point, all the times it failed I had <100meg free
2020-05-15T01:20:42 < qyx> karlp: have you used CP2102 in RS485 mode?
2020-05-15T01:21:47 < Laurenceb> oh yeaaaahhh

2020-05-15T01:24:19 < Laurenceb> nah I havent tried that one

2020-05-15T11:34:56 < PaulFertser> thnx
2020-05-15T11:36:28 < Cracki> I think the mp3 bitstream contains some possibility to sync, so you can seek at an approximate byte address and try decoding. some files may contain an index too, like is usual with video
2020-05-15T11:37:33 < Cracki> if it shows a spectrum it has to decode the whole file anyway.
2020-05-15T11:37:48 < dongs> it does, but it does it way faster than any other tools ive used
2020-05-15T11:37:58 < dongs> ibve been using soundforge 10 because its hte only one that doesnt choke on 1gb files
2020-05-15T11:38:03 < dongs> installed sf13 a while back and its trash
2020-05-15T11:38:10 < dongs> just gonna use this from now on, the thing is great
2020-05-15T11:38:22 < dongs> it takes like a minute to parse 1gb mp3
2020-05-15T11:38:26 < Cracki> lol
2020-05-15T11:38:31 < PaulFertser> I wonder what you're doing with mp3 files that huge
2020-05-15T11:38:46 < dongs> shitforge takes longer and seeks are super slow
2020-05-15T11:38:52 < dongs> the furtther you get into the file
2020-05-15T11:38:54 < dongs> in SF10 anyway
2020-05-15T11:38:58 < Cracki> adobe audition takes a minute to parse any file because it's building the waveform peak view (once)
2020-05-15T11:38:58 < dongs> in SF13 its completely unusable
2020-05-15T11:39:08 < Cracki> a minute per hour of content or so
2020-05-15T11:39:12 < Cracki> perhaps 10 secs
2020-05-15T11:39:34 < Cracki> lol takes longer the further you go in? awful
2020-05-15T11:39:42 < dongs> yeah
2020-05-15T11:39:58 < Cracki> so they don't build any kind of index. shoddy.
2020-05-15T11:40:24 < dongs> they do, but they fail at using it
2020-05-15T11:40:48 < dongs> they make .sfk files which are about 14megs per 1gb of mp3
2020-05-15T11:41:03 < dongs> and i've read them out before its just samples taken at intervals
2020-05-15T11:41:03 < Cracki> that's probably just the peak file
2020-05-15T11:41:05 < dongs> to do peaks
2020-05-15T11:41:06 < dongs> yes
2020-05-15T11:42:10 < Cracki> I have some mp3s that change their duration when I seek in them. they don't come with an index. most do however.
2020-05-15T11:47:31 < dongs> thats just VBR mp3
2020-05-15T11:47:33 < dongs> thats normal
2020-05-15T11:47:49 < dongs> VBR you need to go frame by frame and determine actual length
2020-05-15T11:48:03 < dongs> CBR you just take one frame size and divide by filesize + metadata/wahtever

2020-05-15T15:16:06 < Cracki> Ad0, freertos + newlib? did you set that up right? or did you generate it with cubemx?
2020-05-15T15:16:49 < Cracki> there's some "reent" structure that needs to exist per task
2020-05-15T15:17:39 < Cracki> cubemx has "a bug" there, ST didn't pay any attention
2020-05-15T15:17:54 < Ad0> newlib? I use stm32cubeprogrammer
2020-05-15T15:20:37 < Cracki> that has nothing to do with how you compile it

2020-05-15T15:26:57 < Ad0> hehe
2020-05-15T15:29:15 < Ad0> I have a C++ project in stm32cubemx. on an stm32g030c8. I use ETL and freeRTOS where I have DMA buffer with 64 bytes on UART 1 and 2. that is handled with LL API and setting up interrupts on DMA buffer full / idle detection. it's a C?+ class handling that too. so that class does ospoolcreate and sends a message object with the data on each intererupt to a queue where it's handled in main and routed to the given UART
2020-05-15T15:29:36 < Ad0> sort of like an UART router
2020-05-15T15:29:59 < Ad0> UART -> DMA buffer -> interrupt -> queue -> dispatch to other UART
2020-05-15T15:30:12 < Ad0> so there's a few things going on
2020-05-15T15:30:32 < Cracki> great, cubemx + freertos is fucked
2020-05-15T15:30:53 < Ad0> I am too deep into the rabbit hole to hear that now LOL
2020-05-15T15:30:57 < Cracki> if the compiler is gcc, it's probably using newlib as a c stdlib

2020-05-15T15:33:21 < Ad0> now I have my own ToHexString function
2020-05-15T15:33:22 < Cracki> you'll learn about newlib's malloc and freertos's malloc and you'll learn about that "reent" structure, and that it's fucking huge, and there's... some flag that makes it smaller and stuff is only allocated as needed (needs malloc of course)
2020-05-15T15:33:43 < Cracki> if you use sprintf... don't bother doing your own
2020-05-15T15:34:58 < Ad0> haha 
2020-05-15T15:35:14 < Cracki> this nadler dude's article could use some structure imho
2020-05-15T15:35:18 < Ad0> I just wanted to convert 6 bytes to hex string, that's all 
2020-05-15T15:35:29 < Ad0> so my first approach was sprintf of course
2020-05-15T15:35:37 < Cracki> sure that's very little code. some looping and some math
2020-05-15T15:35:48 < Ad0> yeah I made my own
2020-05-15T15:36:32 < Cracki> I wanted floats so I had to accept newlib. it's ok.

2020-05-15T15:42:23 < Cracki> maybe. I'm tempted. I wonder how those things support you in setting up freertos with newlib.
2020-05-15T15:42:59 < Cracki> I don't think either of them generate code for you like cubemx does

2020-05-15T15:47:15 < Ad0> I am just staying away from stdlib 
2020-05-15T15:47:54 < Ad0> "Typical user symptom: sprintf with floating point doesn't work or crashes.
2020-05-15T15:47:54 < Ad0> "
2020-05-15T15:47:59 < Ad0> that's pretty basic LOL
2020-05-15T15:48:05 < Cracki> ¯\_(ツ)_/¯
2020-05-15T15:48:14 < Cracki> "don't do that then"
2020-05-15T15:48:21 < Cracki> doesn't solve the problem but oh well
2020-05-15T15:48:22 < mawk> that's because of the terribleness of printf
2020-05-15T15:48:23 < Ad0> that's their response?
2020-05-15T15:48:29 < mawk> which does a malloc
2020-05-15T15:48:30 < Cracki> that's everyone's response sadly
2020-05-15T15:48:33 < mawk> the solution is to use a different printf
2020-05-15T15:48:36 < Cracki> yes newlib was done by redhat
2020-05-15T15:48:37 < mawk> or fix newlib to have malloc
2020-05-15T15:48:47 < mawk> you need to provide the relevant syscalls for malloc to work
2020-05-15T15:48:51 < Ad0> I bet ETL has some

2020-05-15T15:58:06 < Ad0> how is it with using newer C++ like C++17? (newer GCC)
2020-05-15T15:59:48 < mawk> well there's no libc++ right
2020-05-15T15:59:50 < mawk> so you're a bit limited
2020-05-15T15:59:55 < mawk> also no exceptions, no RTTI
2020-05-15T15:59:59 < mawk> but you've got virtual functions
2020-05-15T16:00:01 < mawk> and templates
2020-05-15T16:01:33 < dongs> lol jewlib
2020-05-15T16:01:36 < Ad0> that's f ine
2020-05-15T16:02:00 < Ad0> I am using C++ mainly for encapsulation and templates :)
2020-05-15T16:16:23 < Ad0> is it recommended to just stick with the default shipped with stm32cube
2020-05-15T16:17:55 < Cracki> default what?
2020-05-15T16:18:43 < Ad0> build tools
2020-05-15T16:19:27 < Ad0> you have GNU tools for stm32 which is the default. and then there's a choice for GNU arm embedded
2020-05-15T16:19:45 < Cracki> "gnu tools for stm32"?
2020-05-15T16:20:08 < Ad0> yes that's the menu choice in project settings
2020-05-15T16:20:14 < Ad0> more specifically "com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.7-2018-q2-update.win32_1.0.0.201904181610"
2020-05-15T16:20:14 < Cracki> there's gcc for arm with the rest of the toolchain. I think arm actually maintains it.
2020-05-15T16:20:51 < Cracki> ah that, ST of course has to bring that along so they bundle it themselves
2020-05-15T16:20:55 < Ad0> yeahthey have that in there too but it failed to build
2020-05-15T16:21:23 < Ad0> <bits/c++config.h> not found or something
2020-05-15T16:22:07 < Ad0> I would just assume that a newer and more modern toolchain would generate better code but I could be wrong of course lol
2020-05-15T16:22:33 < Cracki> a newer version of gcc, sure
2020-05-15T16:22:39 < Cracki> but that won't solve all the other problems

2020-05-15T16:23:25 < Cracki> a newer compiler won't solve the freertos+newlib interaction config. that always needs to be handled.
2020-05-15T16:23:56 < Cracki> for avr I used to get someone's builds of gcc that were 2-3 major versions ahead (i.e. up to date vs atmel)
2020-05-15T16:24:12 < Cracki> up to date vs gcc development, atmel is very much behind
2020-05-15T16:26:08 < Ad0> Cracki, yeah I meant primarely for code generation and not the newlib issue

2020-05-15T17:07:37 < PaulFertser> Laurenceb: and I'd assume they're different for Li* and Ni*, right?
2020-05-15T17:08:07 < Laurenceb> PaulFertser: aiui for lithium ion you should store in a fridge at about 60% charge
2020-05-15T17:08:19 < PaulFertser> Laurenceb: are you doing that?
2020-05-15T17:08:22 < Laurenceb> yes
2020-05-15T17:08:40 < Laurenceb> I have a sealed container for chemicals and batteries and stuff :P
2020-05-15T17:09:41 < Laurenceb> high charge is bad but overdischarge is also very bad
2020-05-15T17:09:48 < PaulFertser> Laurenceb: and what about your old NiCd?
2020-05-15T17:10:06 < Laurenceb> at ~60% charge there is little degradation and lots of room for self discharge
2020-05-15T17:10:18 < Laurenceb> I regularly use the drill and its stored in a cold basement
2020-05-15T17:10:24 < PaulFertser> Yeah, it's about 3.7 V for Li chemistry, right?
2020-05-15T17:10:35 < Laurenceb> I dont bother to keep charge in a specific range for nicd
2020-05-15T17:10:39 < Laurenceb> yeah about 3.7
2020-05-15T17:11:03 < PaulFertser> BTW, do you know after being fully charged NiCd loses about 20 % in 24 hours?
2020-05-15T17:11:29 < Laurenceb> yeah sounds about right
2020-05-15T17:13:22 < Laurenceb> I was doing some experiments with a "new" battery chemistry last year
2020-05-15T17:13:36 < Laurenceb> but I have too many crazy ideas and need to concentrate on one thing...
2020-05-15T17:14:12 < Laurenceb> basically a rechargeable alkaline cell, but with the pH changed to slightly acidic

2020-05-15T17:16:18 < PaulFertser> Laurenceb: I also have an idea that if a laptop is used mostly on AC power then one should be storing the battery away from it to avoid keeping charged and heated.
2020-05-15T17:16:37 < PaulFertser> Many laptops have stupid proprietary ECs that do not allow to set the charge limit to 80 %.
2020-05-15T17:16:49 < PaulFertser> thinkpads and some dells I guess have that
2020-05-15T17:17:32 < Laurenceb> yeah on babbyshake laptops (thinkpads) I set the limit to 80% without issue

2020-05-15T18:08:39 < PaulFertser> Decompiled your bank app?
2020-05-15T18:09:10 < bitmask> heh something that important is probably more difficult, but no, instacart

2020-05-15T18:10:00 < bitmask> apparently there have been 'services' you can pay for that allow sniping all the good orders, just wanted to see how difficult it is
2020-05-15T18:22:54 < Cracki> so, a java class decompiler eh? are there multiple choices for that?
2020-05-15T18:23:01 < Cracki> what's the recommended one?
2020-05-15T18:27:30 < bitmask> ummm i forget what its called, one sec
2020-05-15T18:28:53 < bitmask> ok so you extract the apk which is just a zip, if its javascript based then no need to go any further as the code is right there. if its java based then you use dex2jar to get the jar file, then you use cfr to decompile the jar into .java files
2020-05-15T18:29:10 < bitmask> there are alternatives for cfr but the guide I was reading said cfr was most reliable
2020-05-15T18:29:33 < Cracki> nice
2020-05-15T18:29:56 < Cracki> I guess the reverse/forward for an apk of the changed code is just as trivial
2020-05-15T18:30:59 < PaulFertser> No :)
2020-05-15T18:31:10 < PaulFertser> You need some special tools to create manifest and sign it.
2020-05-15T18:31:15 < bitmask> well for what I want (figuring out the login procedure/authentication and getting the API keys) is just about reading the code and then you make your own program with what you need.  I'm not sure it completely decomplies everything exactly so I doubt you can just recompile it
2020-05-15T18:31:18 < PaulFertser> It's not just packing it back with zip.
2020-05-15T18:32:03 < Laurenceb> onio: sounds like muh i2c driver for F1

2020-05-15T20:37:56 < Mangy_Dog> it might be listed in the event viewer
2020-05-15T20:38:03 < Mangy_Dog> but i doubt it tbh

2020-05-15T22:34:44 < Cracki> so it's got comparable range with fp32
2020-05-15T22:34:57 < Cracki> they can do standard fp16 and this "brain fart 16" format

2020-05-15T22:36:03 < Cracki> maybe not graphcis
2020-05-15T22:36:17 < Cracki> 8 bit mantissa means ~2 decimal digits
2020-05-15T22:36:43 < Cracki> I think if you express HDR imagery like that you'll start to see banding
2020-05-15T22:37:45 < Cracki> you can tell 6 bit per channel rgb, 8 bit not anymore... unless the screen is shit
2020-05-15T22:38:15 < Cracki> and for geometry that's totally useless. only purpose is inference
2020-05-15T22:38:59 < tomeaton17> its gonna be ages until the benefits reach the consumer anyway
2020-05-15T22:39:05 < Cracki> even then I'm not sure how valuable it is to represent 8 bits of range. they can squeeze networks into int8/int4 already
2020-05-15T22:39:53 < Cracki> the consumer will see raytracing, ai-enhanced imagery, better DSP (somewhere they demoed an audio filter that removes ALL background noise from your microphone)

2020-05-15T22:43:08 < tomeaton17> hm
2020-05-15T22:43:12 < Cracki> joking aside, they use the tensor core stuff to render 3d in "low" res and then blow it up, or resharpen it, or add lighting effects
2020-05-15T22:43:31 < Cracki> and since it's trained on actual content, it can hallucinate that content into the picture you see

2020-05-16T00:21:24 < jadew> obvious spam traps are the best email addresses to have
2020-05-16T00:21:42 < Cracki> the only really spammy emails there come from the official university's job "department" that takes random bartending and office jobs and sends them to our highly qualified STEM students
2020-05-16T00:22:40 < Cracki> totally unfocused. most of these PDFs say "vocational training, bachelor, master, or something"
2020-05-16T00:23:07 < Cracki> +phd. it's all the same to them half the time
2020-05-16T00:23:32 < jadew> it's probably in a list called "Students"
2020-05-16T00:23:39 < Cracki> they all require top grades of course, for the most mind numbing bullshit busywork
2020-05-16T00:24:39 < Cracki> they have pin boards and a searchable table on a web page. there shit is categorized by math/physics, ee, mech eng, taxi driver study

2020-05-16T00:26:41 < Cracki> just now they sent in a phd position, "fully funded", subject contains "AI" and "itsec", but really it's about GDPR for healthcare databases
2020-05-16T00:27:08 < jadew> maybe they want an AI to keep an eye on things
2020-05-16T00:27:21 < jadew> that could be like... 10 maybe 20 years of research

2020-05-16T00:32:57 < Cracki> TIL: german Nuss (nut, like walnut) is hunter's jargon for the female gash, but "(dumme) Nuss" (numb/dumb nut) is also a common insult. now it seems it also means "cunt"
2020-05-16T00:36:10 < jadew> tschuss nuss!
2020-05-16T00:36:36 < jadew> is that a thing?
2020-05-16T00:36:37 < Cracki> wenn schon denn schon, tschüsschen nüsschen
2020-05-16T00:36:57 < Cracki> you need umlaut dots on the tschüss or else it's incomprehensible
2020-05-16T00:37:12 < jadew> heh
2020-05-16T00:37:39 < Cracki> and then you need an ü on the nuss too, which can only be satisfied by -chen

2020-05-16T01:30:06 < zyp> I started out with a bunch of hacked up code that got just enough functionality to receive and reply to the first command the host sends, and the past week I've just been refactoring it into something cleaner

2020-05-16T01:40:54 < catphish> but still not really found a use
2020-05-16T01:43:17 < zyp> usb on the other hand should have a ton of use
2020-05-16T01:44:35 < catphish> it's more that i always consider the commercial value of what i do, and fpga just doesn't compete with stm32 for anything i've wanted to do
2020-05-16T01:44:51 < catphish> because of the £££
2020-05-16T01:47:48 < zyp> well, let's see
2020-05-16T01:48:25 < zyp> isn't this the mcu you went with for your doorlock thing? https://www.digikey.com/product-detail/en/stmicroelectronics/STM32F407VET6/497-12075-ND/2793093
2020-05-16T01:48:42 < zyp> this is the fpga on the board I'm currently playing with: https://www.digikey.com/product-detail/en/lattice-semiconductor-corporation/LFE5U-25F-6BG256C/220-2205-ND/9553918
2020-05-16T01:51:24 < catphish> zyp: https://www.digikey.com/product-detail/en/stmicroelectronics/STM32F407VGT6/497-11605-ND/2747117 but yes
2020-05-16T01:51:48 < catphish> zyp: well lattice has my attention
2020-05-16T01:52:00 < catphish> is that about as cheap as FPGAs get?
2020-05-16T01:52:29 < catphish> zyp: but.... i assume one needs some flash too?
2020-05-16T01:52:43 < zyp> ice40 is smaller and cheaper than ecp5
2020-05-16T01:52:53 < zyp> either are interesting because of the open toolchain support
2020-05-16T01:53:15 < qyx> icq40 \o/
2020-05-16T01:53:18 < catphish> yeah i'd100% consider an fpga that cheap with a free toolchain
2020-05-16T01:53:31 < catphish> but what about supporting components?
2020-05-16T01:53:46 < zyp> and yes, flash is required, also core power regulator
2020-05-16T01:54:02 < catphish> also, i only bought that absurdly expsneive stm32 for ethernet
2020-05-16T01:54:03 < qyx> anyone willing to write me a sgmii switch for ice40?
2020-05-16T01:54:13 < qyx> (idk if possible at all)
2020-05-16T01:54:27 < zyp> haha, ice40 doesn't have serdes
2020-05-16T01:54:34 < zyp> but ecp5 do
2020-05-16T01:54:47 < catphish> my usual choice is https://www.digikey.com/product-detail/en/stmicroelectronics/STM32L433CBT6/497-17961-ND/6621825
2020-05-16T01:54:50 < qyx> :(
2020-05-16T01:54:54 < qyx> no ice40 then
2020-05-16T01:55:33 < catphish> i'll definitely play with ecp5 though
2020-05-16T01:55:56 < catphish> how complex is the supporting circuitrty, flash, power, etc?
2020-05-16T01:56:42 < catphish> and programming / debugging connectivity?
2020-05-16T01:57:11 < catphish> also, at that price, where are the cheap hobby dev boards?
2020-05-16T01:57:37 < zyp> haven't done a board with it myself yet, so I'm not 100% sure but I believe the minimum is core and io voltages and a plain serial flash
2020-05-16T01:57:53 < zyp> catphish, https://www.aliexpress.com/item/32331955683.html
2020-05-16T01:57:59 < zyp> that's the one I've got
2020-05-16T01:58:07 < catphish> yeah i looked at that
2020-05-16T01:58:20 < catphish> but it's not really a dev board
2020-05-16T01:58:42 < catphish> i'd rather pay twice that much and get something that's less of a hack
2020-05-16T01:59:11 < zyp> most other stuff seems to be using larger/more expensive parts
2020-05-16T01:59:52 < zyp> https://www.crowdsupply.com/radiona/ulx3s <- I ordered one of the 85F ones here
2020-05-16T01:59:55 < catphish> what about memory? just make do with programming in some SRAM?
2020-05-16T02:00:21 < zyp> that depends what you need it for
2020-05-16T02:01:14 < catphish> well, ideally i want a purpose built dev board with a crazy cheap part on it
2020-05-16T02:01:20 < catphish> someone should throw one together
2020-05-16T02:01:48 < zyp> the block ram blocks in ecp5 is 2kB each, this 25F got 56 of them and I'm currently using 34
2020-05-16T02:01:49 < catphish> if the part is $11 i'm kinda surprised they haven't
2020-05-16T02:02:27 < catphish> need to get flea on the case
2020-05-16T02:02:37 < zyp> don't remember exactly what they are all used for, I've got one as packet memory for the usb core
2020-05-16T02:02:44 < catphish> are you familiar with https://fleasystems.com/fleaFPGA_Ohm.html
2020-05-16T02:03:03 < zyp> and then I've got a virtual LA that probably uses a couple, and a vexriscv cpu hooked up to more
2020-05-16T02:03:34 < zyp> yeah, I've seen that
2020-05-16T02:03:48 < zyp> looked unobtainable when I looked and also not super interesting
2020-05-16T02:04:01 < catphish> actually that is ecp5, i may be exactly what i want
2020-05-16T02:04:58 < catphish> that flea has 25f in fact :)
2020-05-16T02:05:12 < zyp> https://www.crowdsupply.com/tinyfpga/tinyfpga-ex <- I think this looks interesting, but there doesn't seem to have been any activity for a year
2020-05-16T02:07:28 < catphish> i'm gonna ask mr flea if he still has any
2020-05-16T02:07:42 < catphish> i think he offered me some before but i was into xilinx at the time
2020-05-16T02:07:56 -!- MrMobius [~MrMobius@208.58.206.154] has joined ##stm32
2020-05-16T02:08:17 < zyp> I've got a xilinx fpga on the way in the mail somewhere, but I'm not super enthusiastic about having to install vivado :p
2020-05-16T02:09:54 < catphish> it's certainly bulky, not really my cup of tea, but it works great
2020-05-16T02:10:07 < catphish> you like waiting for things to compile right?
2020-05-16T02:10:33 < zyp> pcie seems fun though
2020-05-16T02:10:34 < catphish> which reminds me, how fast is the open course toolchain? because i'm used to waiting minutes per build :)
2020-05-16T02:11:13 < zyp> well, hard to compare without building the same design on both
2020-05-16T02:11:37 < catphish> but the built in simulation, timing checks, scope probes, etc on vivado are lovely
2020-05-16T02:11:38 < zyp> but hang on, let me time it
2020-05-16T02:12:19 < catphish> even a simple hello world test that passes through some inputs to some outputs is a worthwhile test
2020-05-16T02:12:46 < zyp> my current design is using 35% of the available slices
2020-05-16T02:12:55 < zyp> it's routing now
2020-05-16T02:12:57 < catphish> because in vivado that will take "some time"
2020-05-16T02:13:20 < catphish> it in the order of 1 minute?
2020-05-16T02:13:31 < catphish> if so, i guess it's comparable
2020-05-16T02:13:35 < zyp> real	1m35.712s
2020-05-16T02:13:53 < catphish> okay, then vivado won't be a huge shock :)
2020-05-16T02:14:12 < zyp> well, this is with a whole cpu instance
2020-05-16T02:14:46 < zyp> along with a scope instance, the whole memory infrastructure, a couple of uarts, my usb stuff and some other shit
2020-05-16T02:14:49 < catphish> it was taking a couple of minutes (2,3,5?) for me with a 68k core
2020-05-16T02:14:59 < catphish> so not crazy different
2020-05-16T02:15:18 < zyp> let me try without the cpu
2020-05-16T02:15:37 < catphish> would be nice if it started fast with a simple program
2020-05-16T02:16:29 < zyp> 14% slice utilization without the cpu
2020-05-16T02:16:33 < zyp> real	0m28.623s
2020-05-16T02:16:52 < catphish> that's pretty good
2020-05-16T02:17:18 < catphish> i suspect faster than vivado on my huge chips, but not dramatically so
2020-05-16T02:17:34 < zyp> rumors says it's fast
2020-05-16T02:18:16 < catphish> i enjoy vivado because while it's bulky, it still allows you to start with a totally clean / empty environment
2020-05-16T02:18:35 < zyp> as opposed to what?
2020-05-16T02:19:01 < catphish> ie it doesn't insist on generating you a ton of code you don't want like stmcube
2020-05-16T02:19:29 < zyp> I don't care much for IDE stuff either way
2020-05-16T02:19:52 < catphish> i've never been a fan of bulky IDEs, but vivado somehow doesn't offend me much
2020-05-16T02:20:05 < catphish> and its features are useful
2020-05-16T02:20:36 < catphish> enjoy its several gigabyte installation though
2020-05-16T02:20:39 < zyp> my main issue with vivado at the moment is where the fuck do I install it?
2020-05-16T02:20:53 < catphish> i think it keeps itself tidy in /opt

2020-05-16T02:22:47 < qyx> nah mint
2020-05-16T02:22:57 < catphish> i like my mint
2020-05-16T02:23:14 < zyp> anyway, I figure the simplest solution is to install it on the computer I bought in particular to play with pcie on fpga
2020-05-16T02:23:16 < qyx> hm where do I get an used weller?
2020-05-16T02:23:20 < zyp> did I mention that?
2020-05-16T02:23:33 < qyx> the thing from seeed?
2020-05-16T02:23:44 < zyp> qyx, buy me a jbc nase and I'll give you my weller
2020-05-16T02:23:47 < zyp> yeah
2020-05-16T02:23:50 < qyx> haha
2020-05-16T02:24:10 < zyp> only got 64G emmc, so I'm a bit worried whether vivado will fit :)
2020-05-16T02:24:35 < qyx> it has a m.2, doesn't it?
2020-05-16T02:25:04 < zyp> two, actually, M-key and B-key
2020-05-16T02:25:19 < catphish> i got rid of my flying toys today https://i.imgur.com/0PmGi8p.png
2020-05-16T02:25:24 < zyp> I'll be using the M-key slot for the fpga board, that was the whole point of getting it in the first place
2020-05-16T02:25:33 < catphish> seems i no longer play with them :(
2020-05-16T02:25:35 < zyp> but I think it'll work to stick a sata ssd in the B-key slot
2020-05-16T02:25:39 < qyx> b-key is sata?
2020-05-16T02:26:12 < zyp> I think both can be either, but M-key is four lanes, B-keys is two IIRC
2020-05-16T02:26:24 < catphish> i need to learn about pcie, seems the cool kids are using it for all sorts, and its very fast and very tolerant
2020-05-16T02:26:42 < zyp> so I get the impression pcie ssds are M-key and sata ssds are dual B+M-key
2020-05-16T02:27:04 < catphish> can one dual master pcie at all?
2020-05-16T02:27:06 < qyx> I am using PCIe xonmmectors only
2020-05-16T02:28:11 < zyp> catphish, my understanding is that there's always one root, but other nodes can also master the bus, which is mainly used to DMA to host memory, but can also be used for other stuff
2020-05-16T02:28:40 < catphish> zyp: i'm thinking along the lines of connecting 2 PCs to one SSD
2020-05-16T02:29:41 < zyp> one thing I find interesting is that I can apparently export some memory space from a fpga over pcie and then mmap() that directly into a userland process
2020-05-16T02:29:55 < catphish> nice
2020-05-16T02:30:34 < catphish> yeah i'd definitely like to play with that
2020-05-16T02:31:26 < zyp> which means that I should be able to instance a bunch of memory mapped peripherals on the FPGA, take some mcu firmware that would talk to the peripherals and build them as a normal userland process, mmap the peripherals into the process and run it on the host
2020-05-16T02:31:33 < zyp> I just wonder how latency will be
2020-05-16T02:31:48 < zyp> I guess it'll work for anything that's not too timing critical
2020-05-16T02:32:00 < zyp> which could be a cool way to test and debug firmware
2020-05-16T02:32:28 < catphish> i imagine 1) pcie is fast 2) most things are not timing critical if implemented well
2020-05-16T02:32:44 < zyp> develop on host but with real hardware, then pack it up and stick it onto a riscv in the fpga
2020-05-16T02:33:15 < catphish> sounds cool
2020-05-16T02:33:25 < zyp> pcie is fast, but throughput != latency
2020-05-16T02:33:52 < zyp> and there's also scheduling latency to consider when you're a userland process rather than running on bare metal
2020-05-16T02:34:22 < zyp> anyway, I'm totally gonna experiment with that once the fpga board shows up
2020-05-16T02:35:10 < zyp> if it works well, I'd consider making an ecp5-based board in the m.2 form factor, but apparently there's no opensource pcie for ecp5 yet
2020-05-16T02:35:37 < zyp> which I guess is another rabbit hole I could fall into at some point :p

2020-05-16T14:55:55 < strata> payday monsanto said billy boy is launching the seattle space needle into space to vaccinate the world.
2020-05-16T14:59:09 < Steffanx> Can you speak less cryptic strata?
2020-05-16T14:59:25 < Steffanx> It became even worse after you went incognito 
2020-05-16T14:59:49 < Steffanx> Or is Tor obfuscating it?
2020-05-16T15:01:18 < strata> Steffanx, "payday monsanto" is an american rapper who made a skit video of himself doing a crude deep-fake of bill gates claiming responsibility for sars-cov-2 and describing his plans to launch the seattle space needle into space to do a mass vaccination.
2020-05-16T15:01:32 < strata> it was a parody
2020-05-16T15:02:51 < Steffanx> -_-
2020-05-16T15:06:21 < Cracki> is it my imagination or does ULA copy spacex's webcast format? they use the same phrases, same camera angles, try for similar quality

2020-05-16T15:21:39 < benishor> heh
2020-05-16T15:23:30 < Steffanx> Benishor if youre using HAL stuff.. there are i2s examples in the cube.
2020-05-16T15:24:23 < Steffanx> And when youre lazy you clickerly click it together in the cubeMX
2020-05-16T15:24:59 < benishor> I have something that works with 16bit in mbed (I know) and I want to switch to 24/32bit since I need more dynamic range and the codec supports 24 bit
2020-05-16T15:25:19 < benishor> so I just need a sample in order to patch stuff
2020-05-16T15:25:40 < benishor> need to see how to set up i2s, sai and dma
2020-05-16T15:25:53 < benishor> for that particular context
2020-05-16T15:26:36 < Cracki> cubemx for the basics, then scan RM for which registers to put what magic numbers into

2020-05-16T15:31:46 < Cracki> ahem, what you're used to finding in normal data sheets is split into the "data sheet" (ratings, timings, etc), the "reference manual" (functional description, register maps, ...), and then some more, among which is one that explains the ARM core which you don't usually need

2020-05-16T19:28:45 < Cracki> search for suicide, google pretends your life has value. bing otoh is actually being helpful and tells you the most effective methods
2020-05-16T19:29:22 < Cracki> if google valued life on earth, it wouldn't suspiciously omit any and all holidays that are commonly celebrated in europe
2020-05-16T19:30:07 < kakimir> holidays?
2020-05-16T19:30:50 < emeb> wait - europeans can actually agree on holidays?
2020-05-16T19:31:07 < Cracki> we could if you would let the germans dictate them
2020-05-16T19:31:41 < Steffanx> The christians did a pretty good jb
2020-05-16T19:31:50 < Cracki> joking aside, google is being very inclusive about all other holidays, but not even selective but _exclusive_ about holidays you can find in europe
2020-05-16T19:32:55 < Cracki> it's not just showing you localized content. it's literally showing nothing at all if the day is an european holiday

2020-05-16T19:43:52 < Laurenceb> maps was good when it first appeared

2020-05-16T19:45:24 < Laurenceb> but lots of huge adverts cuz thats what its really for
2020-05-16T19:47:11 < emeb> Someone recently pointed out that the downfall of Google began when they bought Doubleclick.net and got eaten from the inside out by it.
2020-05-16T19:48:27 < Laurenceb> lol that explains their cancerous advertising
2020-05-16T19:48:50 < Laurenceb> >still no contours on google maps

2020-05-16T19:57:34 < emeb> You have to learn a lot of dumb quirks though.
2020-05-16T19:58:19 < Thorn> what about linux though? for example ST boasts the fact that their linux is mainline and you're not locked into a specific kernel etc.
2020-05-16T19:58:54 < emeb> I've got no experience w/ linux on ST stuff
2020-05-16T20:00:21 < emeb> And doing linux on Zynq is so tied up with various flavors of OpenEmbedded

2020-05-16T21:02:52 < Thorn> ok can someone explain this
2020-05-16T21:02:53 < Cracki> at least the doodle for ramavan was just fanfiction
2020-05-16T21:02:55 < mawk> Macron told all muslims to have a good aïd on national tv

2020-05-16T21:03:12 < mawk> yeah
2020-05-16T21:03:55 < Thorn> the mounting holes on this display module are connected together by a wide trace, but it's not gnd. actually there's a solder bridge (not soldered) between it and the gnd pin 
2020-05-16T21:04:15 < Cracki> does it touch anything
2020-05-16T21:04:26 < Cracki> maybe this is an optional way for easy ground, and they leave you the choice
2020-05-16T21:05:35 < Thorn> it also connect to the metal housing around the actual lcd
2020-05-16T21:05:41 < Thorn> nothing else afaict
2020-05-16T21:06:07 < Cracki> grounding to case seems to be a contentious topic
2020-05-16T21:06:19 < Thorn> annular rings around mounting holes, the housing and the solder bridge to gnd it (which is not shorted from the factory)
2020-05-16T21:07:10 < Thorn> the module is pretty large, almost 300mm long

2020-05-16T23:48:54 < mawk> yes
2020-05-16T23:49:11 < mawk> the law is there so that we're not allowed to tell a fat black woman she's fat or that she's black
2020-05-16T23:50:44 < mawk> her last name is Avia, that means bird in latin
2020-05-16T23:50:48 < mawk> prefectly suited to her

2020-05-16T23:52:13 < mawk> bestest culture if you ask a frenchman

2020-05-17T00:11:35 < Cracki> careful with "nobody to oppose it". that's "consensus" and a very commie idea. it blocks all action if just one feels like throwing a temper tantrum
2020-05-17T00:12:34 < Cracki> this can only work with high trust groups and it still needs sanctions for dissent, which nobody is forward thinking enough to ask for in practice https://en.wikipedia.org/wiki/Consensus_decision-making
2020-05-17T00:13:32 < Cracki> the system of incentives is broken. they have no reason to improve, and every reason to keep their swamp wet.

2020-05-17T01:12:34 < jadew> the guy said it got like that in a few seconds
2020-05-17T01:12:46 < jadew> I wonder if Metcal can do that?
2020-05-17T01:19:18 < PaulFertser> Metcal (the old one with fixed tip temperature) can't do that by the very nature of their heating process
2020-05-17T01:21:15 < jadew> so KSGER > Metcal.
2020-05-17T01:21:21 < PaulFertser> TS100 can glow too if heating is never stopped. And few seconds reported might be 10 or 20, who knows.
2020-05-17T01:21:35 < jadew> yeah :)
2020-05-17T01:22:03 < PaulFertser> Metcal tip can't be (considerably) overheated anyhow, no matter how much power you pump to it.
2020-05-17T01:23:36 < zyp> that's because it stops taking power

2020-05-17T02:37:04 < Thorn> the coin cell is there to keep the sram alive
2020-05-17T02:37:41 < Thorn> package is called sTSOP
2020-05-17T02:37:57 < zyp> what's the sim socket for? secure element?
2020-05-17T02:38:38 < Thorn> the version that I have has an unpopulated gsm modem instead of the huge ldo and caps
2020-05-17T02:38:55 < Thorn> but since this one also has a sim socket it's an interesting question
2020-05-17T02:39:35 < Thorn> I might dig through their docs to find out
2020-05-17T02:40:32 < zyp> doesn't make sense for the socket to be populated if the only modem it could be used with was unpopulated
2020-05-17T02:41:10 < zyp> so unless gsm modem plugs into that header row or something, I assume it's something else, like a secure element for authenticating with the server or something

2020-05-17T03:09:25 < Laurenceb> I guess a captive sphere with caser wheels around it might work

2020-05-17T15:57:09 < dongs> never mind im blind
2020-05-17T15:57:13 < boddax_> yes tiles
2020-05-17T15:57:13 < Steffanx> luckily its already 14:57
2020-05-17T15:57:31 < boddax_> Steffanx on board?
2020-05-17T15:57:32 < Cracki> clip show, replays
2020-05-17T15:58:05 < Steffanx> lol no boddax_, its what you get when you omit the time zone :P
2020-05-17T15:58:32 < Cracki> fucking muricans should know better. their country spans a handful of time zones
2020-05-17T15:58:48 < Steffanx> it actually says " 9:14 a.m. EDT" 
2020-05-17T15:58:58 < Cracki> muricans best ppl
2020-05-17T15:59:04 < boddax_> yes
2020-05-17T15:59:19 < boddax_> USA the best
2020-05-17T15:59:35 < Steffanx> dutchland is 2nd best.
2020-05-17T16:00:45 < Steffanx> We even have a promotion video for it https://www.youtube.com/watch?v=ELD2AwFN9Nc
2020-05-17T16:01:44 < jadew> man.. elecrow is full of bullshit
2020-05-17T16:01:54 < dongs> you get what you pay for
2020-05-17T16:02:20 < jadew> they're telling me the package is waiting for flights in HK, and another package from HK, sent weeks after theirs (last week more precisely), is already in the EU
2020-05-17T16:03:02 < Cracki> great wall
2020-05-17T16:03:23 < jadew> it got to HK yesterday, today is in Germany
2020-05-17T16:03:45 < boddax_> USA first ..2nd Italy because we teach them how to be first
2020-05-17T16:03:52 < Cracki> germans call it "Schneckenrennen" and I think it's beautiful
2020-05-17T16:04:13 < dongs> jadew: the last weeks package was already on HK and in a plane.
2020-05-17T16:04:23 < Steffanx> DHL track and trace is bullshit
2020-05-17T16:04:25 < dongs> how do youi expect somethign sent a week LATER to take same amount of time?
2020-05-17T16:04:44 < Steffanx> You can use 3 different website of DHL to get 3 different statusses
2020-05-17T16:05:43 < Cracki> so this tax evasion thing they mention in the video, is that real and how much trouble is it to use
2020-05-17T16:05:59 < boddax_> i ve been in HK airport ..theyr internal train to transfer between the gates when it start if you dont hold very well from the first wagon you fly in the last
2020-05-17T16:06:00 < Steffanx> Order something in germany, use dhl.de. They hand it over at the border and stop tracking. So ill have to use dhl-parcel to continue tracking.. its great. its awesome.
2020-05-17T16:06:19 < jadew> dongs, you got something delivered from HK last week?
2020-05-17T16:06:50 < jadew> Steffanx, dhl.de is different from the DHL in your country
2020-05-17T16:07:05 < jadew> DHL Express is a fast courier, dhl.de is snail mail
2020-05-17T16:07:27 < jadew> they own DHL Express, but it's a different company
2020-05-17T16:07:46 < Steffanx> even with express it see it happen. where different websites gives you different status info
2020-05-17T16:07:48 < boddax_> i got pack from banggood last week tracking says still in HK even now
2020-05-17T16:09:19 < boddax_>  EU Priority Line
2020-05-17T16:09:27 < Steffanx> Cracki the letterbox company business in dutchland is pretty large. Although i believe it changed a bit recently due to a change in tax regulation/rules.
2020-05-17T16:10:46 < Steffanx> oh the countdown continued.

2020-05-17T16:57:45 < englishman> Laurenceb: what's more efficient, heating an outdoor greenhouse in -20C ambient and using natural light, or using a fully insulated grow room with HID lights?
2020-05-17T17:04:25 < Laurenceb> hmm
2020-05-17T17:04:41 < Laurenceb> double glased greenhouse ftw
2020-05-17T17:06:23 < Laurenceb> yeah probably more efficient to heat the greenhouse, especially if you have a cheap stove and even more if its double glased
2020-05-17T17:06:54 < BrainDamage> englishman: do you have the outdoors greenhouse already?
2020-05-17T17:07:14 < BrainDamage> if yes, get an IR thermometer, it'll work like a 1 pixel thermal camera
2020-05-17T17:07:27 < BrainDamage> you can find your thermal leaks easily this way
2020-05-17T17:07:50 < englishman> Laurenceb: electric heat. even with the poor winter light and short daylight hours?
2020-05-17T17:07:59 < Laurenceb> sheeet wtf canada
2020-05-17T17:08:15 < Laurenceb> in uk I'd just get a wood stove from ebay

2020-05-17T17:09:13 < Laurenceb> hmm yeah indoor growroom is prob a bit better then
2020-05-17T17:09:28 < karlp> BrainDamage: shush, it's a perfect excuse to justify a thermal camera ;)
2020-05-17T17:10:34 < englishman> BrainDamage: just a temporary greenhouse, starting to design a large one, pondering the efficacy of actually using the thing year round
2020-05-17T17:10:52 < Laurenceb> hmm from that site I get about breakeven at 7 hours of daylight
2020-05-17T17:11:04 < Laurenceb> and heating from -20 to +15C
2020-05-17T17:11:25 < BrainDamage> englishman: still a good testbed
2020-05-17T17:11:54 < Laurenceb> not much in it
2020-05-17T17:12:34 < BrainDamage> for one, you can estimate the thermal leak
2020-05-17T17:12:45 < englishman> how about I just use the thermal camera? anyway, the problem at the moment is ventilation, the weather is too nice
2020-05-17T17:12:56 < BrainDamage> once you know the thermal resistance, you'll know how much it'll leak in the winter
2020-05-17T17:13:29 < BrainDamage> currently it's empty, right?
2020-05-17T17:13:31 < englishman> yes I can get the r rating of the panels and doors. it will probably be r8
2020-05-17T17:13:57 < englishman> no about 1/4 of the plants are in it
2020-05-17T17:14:41 < BrainDamage> mmm, umidity and biological processes might make the temp fluctuate not in response to the sun
2020-05-17T17:15:05 < BrainDamage> I was thinking, just look at insolation measurement for the day, compare to the temperature and then you'll know your leak

2020-05-17T17:18:24 < englishman> oh the greenhouse right now isn't representative of a permanent one. it's just some plastic (pe?) sheet on a frame
2020-05-17T17:22:47 < Laurenceb> should be similar to single glased glass
2020-05-17T17:23:12 < Laurenceb> maybe a double PE greenhouse would work, but it would lose quite a lot of light
2020-05-17T17:23:50 < Ecco> Hi everyone :)
2020-05-17T17:24:11 < Laurenceb> I have about 150 1.5x1.5m double glased planels for free
2020-05-17T17:24:20 < Laurenceb> but shipping to canada would be expensive
2020-05-17T17:25:03 < Ecco> I was wondering: is it possible to completely prevent writing to the Flash memory of an STM32? Virtually turning it into a ROM?

2020-05-17T20:18:15 < Cracki> I definitely see the appeal of putting an os and the toolchain on this. then you can just dump it in a project box and pull it out whenever

2020-05-17T21:51:40 < jadew> I'm trying to buy a CNC, but I can't find the usual information you find for other stuff
2020-05-17T21:52:15 < jadew> very few videos, very few blog posts helping you sort things out
2020-05-17T21:52:43 < jadew> and there doesn't seem to be a go-to CNC you can get on a budget, that just works and is good enough, like in the case of 3D printers
2020-05-17T21:52:52 < jadew> on a budget meaning < 2k
2020-05-17T21:53:29 < Ultrasauce> anything at that price point is a toy
2020-05-17T21:53:43 < jadew> Ultrasauce, really?
2020-05-17T21:53:46 < jadew> why tho?
2020-05-17T21:54:22 < jadew> a decent spindle seems to cost ~800 EUR from a european company
2020-05-17T21:54:33 < jadew> the frame and the motors can't cost that much, can they?
2020-05-17T21:55:09 < jadew> the pricing really makes no sense, especially since the chinese crap doesn't come with proper software licenses
2020-05-17T21:55:14 < Cracki> frame needs to be properly rigid
2020-05-17T21:55:19 < jadew> they expect you to find some opensource thing
2020-05-17T21:55:39 < jadew> Cracki, sure, but I would think you could make a good frame in that money
2020-05-17T21:55:47 < Cracki> random CNCs you'll find may mill wood and plastics, maybe aluminium
2020-05-17T21:55:56 < jadew> you can get a freaking mill that's solid steel for less
2020-05-17T21:55:59 < Cracki> for that money, they make GOOD PROFITS
2020-05-17T21:56:10 < Cracki> not much competition in that segment yet
2020-05-17T21:56:33 < jadew> yeah, that's my feeling as well
2020-05-17T21:56:56 < Cracki> motors and power electronics cost a good bit
2020-05-17T21:57:08 < jadew> I wonder if I should get a mill and equip it with a 24k RPM spindle
2020-05-17T21:57:12 < Ultrasauce> you can get a decent desktop manual mill for about that money
2020-05-17T21:57:22 < jadew> Ultrasauce, exactly
2020-05-17T21:57:42 < jadew> for 2k you can get a really good mini mill
2020-05-17T21:57:58 < Cracki> what material are you looking to mill
2020-05-17T21:58:16 < jadew> for 2k in the CNC world, you seem to only get to choose between aluminium frames and china spindle
2020-05-17T21:58:30 < jadew> Cracki, aluminium and brass
2020-05-17T21:59:14 < Cracki> 140 bucks: https://www.youtube.com/watch?v=bUkX3iwr2iE
2020-05-17T21:59:20 < Cracki> (shit)
2020-05-17T21:59:54 < jadew> yeah, I want it to mill better than that
2020-05-17T21:59:56 < Cracki> I guess if you want to build your own frame, you could upgrade that well enough
2020-05-17T22:00:15 < jadew> well, if I'm gonna make my own frame, I'll do it all from scratch
2020-05-17T22:00:34 < jadew> but yeah, I've considered that too
2020-05-17T22:01:08 < Cracki> I guess you've found this already https://all3dp.com/1/best-diy-cnc-router-kit/
2020-05-17T22:01:37 < jadew> I haven't
2020-05-17T22:01:40 < Cracki> most of those are not much sturdier than a random 3d printer
2020-05-17T22:01:43 < jadew> thanks, I'll check it out
2020-05-17T22:01:50 < jadew> yeah, that bothers me
2020-05-17T22:01:51 < Cracki> and not for metal
2020-05-17T22:02:02 < jadew> I'm really tempted to make my own frame from steel
2020-05-17T22:02:27 < Cracki> the frame is rigid enough quickly. enough aluminium does the job.
2020-05-17T22:02:35 < Cracki> the problem is all the bearings, or lack of them
2020-05-17T22:02:37 < jadew> my shop is located between the biggest metal working factories in the countries
2020-05-17T22:02:46 < jadew> if I come up with a design, I'm sure they can make it for me
2020-05-17T22:03:00 < jadew> *country
2020-05-17T22:03:19 < Cracki> I'm sure they would even design it for you, or they have designs already
2020-05-17T22:03:33 < jadew> I would just prefer a ready-made variant that I can just put together
2020-05-17T22:03:41 < jadew> don't want a project
2020-05-17T22:04:20 < Cracki> my boss once told me a few german companies that sell that kinda mill
2020-05-17T22:05:00 < Cracki> one was "bzt", i think, and another was even a customer of his, and they called themselves "stepcraft"
2020-05-17T22:05:30 < Cracki> the stepcraft stuff is very make:r grade tho
2020-05-17T22:06:25 < jadew> stepcraft seems to have a romanian website too
2020-05-17T22:06:36 < Cracki> those portal style ones can't compete with the big ones. at least one digit difference in price
2020-05-17T22:07:22 < zyp> if I want something cheap that can do holes and engraving in aluminum front panels, what do I get?
2020-05-17T22:07:52 < jadew> zyp, 3040 or 6040 cnc from china
2020-05-17T22:08:00 < jadew> 400-500W +
2020-05-17T22:08:12 < jadew> not sure about the holes
2020-05-17T22:08:28 < zyp> I don't need a lot of work area
2020-05-17T22:08:31 < jadew> it will mill holes, but drilling will be trickier
2020-05-17T22:08:59 < Cracki> heh stepcraft says they can go 16mm/s through aluminium "knead alloy"
2020-05-17T22:09:03 < Cracki> https://www.stepcraft-systems.com/cnc-maschinen/cnc-systemuebersicht
2020-05-17T22:09:14 < Cracki> drilling sounds easier, just go down
2020-05-17T22:09:38 < jadew> it isn't
2020-05-17T22:09:49 < jadew> you need a lot of force for drilling
2020-05-17T22:09:58 < jadew> they would have to mill the hole
2020-05-17T22:10:03 < jadew> I'm not sure what the operation is called
2020-05-17T22:10:17 < jadew> for drilling you also need lower speed, which those CNCs can't do
2020-05-17T22:10:20 < Cracki> that dude with the 140 bucks thing had trouble engraving his pcb because he clamped it wrong, and it warped, and when you engrave a pcb you need to keep precise distance
2020-05-17T22:10:24 < jadew> you could do drilling on a proper milling machine tho
2020-05-17T22:10:33 < Cracki> ic
2020-05-17T22:11:08 < zyp> a mill is probably more suited than a router for what I'd like to do
2020-05-17T22:11:31  * Cracki googles diff between mill and router
2020-05-17T22:12:10 < jadew> zyp, that's what I think too, but I'm not 100% sure
2020-05-17T22:12:24 < jadew> commercial CNC shops that are making my stuff are still using high spindle speeds
2020-05-17T22:12:38 < jadew> so there's probably some advantage to it, I just don't know what that is
2020-05-17T22:12:54 < jadew> maybe they do high speed because they have high torque too?
2020-05-17T22:13:01 < jadew> and they advance much faster
2020-05-17T22:13:14 < jadew> on a small CNC you do high speed because you don't have the torque
2020-05-17T22:13:17 < jadew> hmm
2020-05-17T22:13:28 < Cracki> ah, router is for soft stuff and does RPMs, not torque
2020-05-17T22:13:35 < jadew> yeah
2020-05-17T22:13:41 < Cracki> high speed milling because they can do it, and it's faster
2020-05-17T22:13:53 < jadew> on the other hand, a I think a router would handle front panels just fine
2020-05-17T22:14:00 < jadew> without needing a lot of rigidity
2020-05-17T22:14:15 < Steffanx> how fast do you want it to be anyway?
2020-05-17T22:14:15 < jadew> while a mill, would have to be really good to make straight holes in sheet metal
2020-05-17T22:14:24 < jadew> Steffanx, I don't really care about speed
2020-05-17T22:14:51 < jadew> (sheet metal is tricky to drill, even on a drill press)

2020-05-17T22:15:13 < Cracki> ah! stepcraft et al are "routers", not mills
2020-05-17T22:16:06 < Cracki> makes sense, going by what google shows me for "router tool"
2020-05-17T22:16:21 < Steffanx> I want a lathe although i might not have a real use for it. And it's a damn scary machine.
2020-05-17T22:16:35 < Steffanx> I just did something on my CNC/router that would have been so much easier on a lathe.
2020-05-17T22:16:37 < jadew> Steffanx, yeah, I want one too
2020-05-17T22:16:42 < jadew> and yes, it's also very scary
2020-05-17T22:16:54 < jadew> don't wear long sleeves when working it

2020-05-17T22:24:48 < Cracki> offer them to supervise a workshop class? or hold computer class in exchange for machine time? :>
2020-05-17T22:33:50 < PaulFertser> I haven't visited my school for like 18 years. And I live ~25 km away from it now.
2020-05-17T22:34:13 < PaulFertser> I am not sure schools still feature lathes, it might be considered too dangerous these days.
2020-05-17T22:34:38 < Steffanx> nah
2020-05-17T22:34:39 < Cracki> yeah kids these days are _all_ long haired
2020-05-17T22:34:43 < Steffanx> if its a tech chool why?
2020-05-17T22:35:02 < Steffanx> kids still have to learn it
2020-05-17T22:35:14 < PaulFertser> I was long haired back then too, guess I was using something to make it safe. 
2020-05-17T22:35:27 < Cracki> my school had no workshop to speak of but the mother of someone I knew was a teacher at a tech school. they had lathes and mills and routers and all of that again with CNC
2020-05-17T22:35:28 < PaulFertser> It's not a tech school, it was a regular post-soviet school.
2020-05-17T22:36:11 < Cracki> soviet, then I'd definitely expect that
2020-05-17T22:36:41 < PaulFertser> We didn't really study machining anyhow, iirc we were too young for that. Many would have difficulties even using calipers :)
2020-05-17T22:36:50 < Cracki> *g*
2020-05-17T22:37:30 < Cracki> around here you can enter vocational school at 15/16, it's usually for about 3 years (then you're 19) and if you're apprenticing for metal work you will learn this for sure.
2020-05-17T22:37:53 < Cracki> I think upper classes even of brainy high schools could handle this stuff... maybe as an elective course
2020-05-17T22:37:54 < PaulFertser> Indeed. But we were few years younger than that.
2020-05-17T22:38:10 < jadew> we did basic metal work in gymnasium (5th to 8th grade)
2020-05-17T22:38:26 < jadew> in one class we made nuts
2020-05-17T22:38:37 < jadew> cut the steel, drilled it, tapped it
2020-05-17T22:38:40 < jadew> that was fun
2020-05-17T22:38:40 < Cracki> same. we were maybe 10/11 when we had shop class, and that was all over the place. some wood, some sewing, some metal, some plastic bending, ...
2020-05-17T22:38:49 < Cracki> :D
2020-05-17T22:39:26 < jadew> I'm still friends with that teacher and I visit him whenever I'm in town
2020-05-17T22:42:18 < PaulFertser> I remember we were making knives from bow saw blades. And if you did it good enough the teacher was sharpening it and you carried it home :)
2020-05-17T22:49:08 < jadew> we made dustpans from sheet metal at one point
2020-05-17T22:49:52 < jadew> and an attachment for a mincing machine, that was used for making sausages
2020-05-17T22:49:58 < jadew> and we soldered it with leaded solder :D
2020-05-17T22:50:02 < PaulFertser> :D

2020-05-17T22:51:03 < PaulFertser> I think we assembled some shelves (almost ikea-style easy job), probably commercially sold after that by the school :)
2020-05-17T22:52:00 < jadew> Cracki, I like how the belly ring is part of the discussion about throwing a net
2020-05-17T22:52:05 < Cracki> :P
2020-05-17T22:52:55 < jadew> oh, we did some engraving too
2020-05-17T22:53:18 < jadew> I drew donald duck on a piece of wood, with an engraving machine
2020-05-17T22:53:32 < Cracki> all we did is take a soldering iron to some wood for "engraving"
2020-05-17T22:53:51 < jadew> well, it looked like a soldering iron, but it was specifically made for engraving
2020-05-17T22:53:59 < PaulFertser> Guess what dongs were drawing when they were at school.
2020-05-17T22:54:20 < Cracki> clam
2020-05-17T22:54:36 < PaulFertser> Yes, I have special wood engraving device too. For some reason it was popular in the ussr.
2020-05-17T22:55:26 < jadew> when we were doing this stuff, the girls in our class were learning to sew :P
2020-05-17T22:55:35 < englishman> qyx: is there a way to use the rak pilot gateway directly with influxdb? or maybe with those mikrodik units? don't the packets need to be decoded/processed somewhere? as in, the app layer
2020-05-17T22:55:50 < PaulFertser> Our girls were learning to cook too.
2020-05-17T22:56:13 < jadew> neat, we didn't have the facilities for that
2020-05-17T22:56:17 < qyx> englishman: I'll tell you in few months
2020-05-17T22:56:19 < PaulFertser> Probably it would be more useful if everybody was learning to cook.
2020-05-17T22:56:30 < qyx> englishman: so far no lorawan here
2020-05-17T22:56:38 < jadew> PaulFertser, then you wouldn't have an incentive to get married
2020-05-17T22:56:57 < jadew> 90% of men are married because they can't cook
2020-05-17T22:57:13 < PaulFertser> jadew: guess I'm among the 10 % then.
2020-05-17T22:57:26 < jadew> I'm pulling that out of my ass, but I can't cook
2020-05-17T22:57:37 < jadew> I tried a couple of times when I was single and it was a complete disaster
2020-05-17T22:57:39 < Cracki> no cooking for us. best they could do was "how to wash scraps of cloth in a beaker"
2020-05-17T22:57:58 < Cracki> you learn
2020-05-17T22:58:18 < PaulFertser> Simple cooking is trivial though, you can either eat it raw or if it's unsuitable, boil it till ready.
2020-05-17T22:58:20 < Cracki> start with cooking water. next time add salt. next time a lot more. next time throw in some noodles.
2020-05-17T22:58:37 < jadew> I'm sure, but I only tried it when I was broke, once I got a job I just ordered whatever I wanted
2020-05-17T22:59:18 < englishman> qyx: getting mikrodik stuff? I don't see anything on their website
2020-05-17T22:59:20 < jadew> I tried to make chicken soup, didn't know you have to unfreeze the chicken for like... half a day
2020-05-17T22:59:27 < Cracki> one day I said, I'ma make scrambled eggs, and I got some eggs and whacked them (and nothing else) into the teflon pan and went at them with the spatula until it looked ok
2020-05-17T22:59:39 < Cracki> tasted bland but ok
2020-05-17T22:59:43 < jadew> I tried to do it in the microwave oven, and it boiled on the surface, but it was still frozen on the inside
2020-05-17T22:59:59 < Cracki> microwave should have heated it everywhere?
2020-05-17T23:00:10 < PaulFertser> No, 2.4 GHz is not penetrating deep.
2020-05-17T23:00:12 < Cracki> microwaves have thaw mode
2020-05-17T23:00:19 < jadew> yeah, it's not penetrating...
2020-05-17T23:00:20 < Cracki> takes a while but only heats it a little
2020-05-17T23:00:23 < Cracki> til
2020-05-17T23:00:49 < qyx> englishman: I want to try their minipci-e lorawan card in my device, it should communicate ins ome standard json format and theres a lib for it on github
2020-05-17T23:00:55 < jadew> scrambled eggs are easy tho
2020-05-17T23:00:59 < Cracki> makes sense tho. radiation is absorbed, so it should decay the further it penetrates
2020-05-17T23:01:06 < jadew> soup - super difficult
2020-05-17T23:01:25 < Cracki> how to make soup: open the can, pour into bowl, microwave it
2020-05-17T23:01:39 < PaulFertser> btw, I had tracheitis treated with 2.4 GHz waves, worked wonders.

2020-05-17T23:02:44 < Cracki> when I did my civil service, some grown woman wondered why I'd say the cafeteria's pudding is "just" powdered instant stuff. she had no idea people made pudding from actual real ingredients, at home
2020-05-17T23:02:53 < PaulFertser> Well, I had it for few months and then it started to improve. And you really feel the warmth where you put the radiating antenna.
2020-05-17T23:03:19 < Cracki> how do they treat tracheitis with radio waves?
2020-05-17T23:03:42 < jadew> if google is right and it's bacterial in nature, then it might kill bacteria
2020-05-17T23:03:54 < PaulFertser> You hold the directed antenna  as close to trachea as possible, it radiates.
2020-05-17T23:04:11 < Cracki> I would hope it'smore than 2.4 ghz or else it penetrates quite a bit deeper than just a surface layer of bacteria
2020-05-17T23:04:15 < jadew> wait, this happened from the outside?
2020-05-17T23:04:20 < PaulFertser> Yes
2020-05-17T23:04:24 < jadew> you didn't have that shoved down your throat?
2020-05-17T23:04:25 < jadew> hmm
2020-05-17T23:04:29 < Cracki> wat
2020-05-17T23:04:50 < jadew> and you're sure it penetrated that deep?
2020-05-17T23:04:52 < Cracki> that ought to heat up your skin more than anything else
2020-05-17T23:05:01 < Steffanx> <PaulFertser> Our girls were learning to cook too. <= here the boys had to do that too. Me included.
2020-05-17T23:05:13 < PaulFertser> I guess 1-2 cm are reasonable to expect, so not just the skin.
2020-05-17T23:05:27 < Cracki> hm
2020-05-17T23:05:41 < Cracki> russian medicine is entirely unknown to the western world
2020-05-17T23:05:43 < PaulFertser> Steffanx: I guess it's fun. Instead of doing boring math you cook and eat in a good company.
2020-05-17T23:05:47 < Cracki> phage therapy and all that
2020-05-17T23:06:08 < Cracki> same with russian history, westerners could learn so much, and see the parallels
2020-05-17T23:08:53 < Steffanx> PaulFertser:  it was more than that. It was all the "house holding" stuff (sewing, cooking etc.) 1.5 hours/week. It wasn too bad, but no fun at that age either.
2020-05-17T23:09:22 < Steffanx> Even sex education was part of that class :D
2020-05-17T23:09:30 < PaulFertser> Steffanx: hm, I think girls here did sewing too.
2020-05-17T23:11:25 < Steffanx> :)
2020-05-17T23:11:51 < Steffanx> its not bad for a 12-14 year old boy to learn the very basics of it al.
2020-05-17T23:11:52 < PaulFertser> https://mmt.zp.ua/img/shop/goods/2277.jpg 2375+47,5 MHz , output power 2.5 -- 20 W
2020-05-17T23:12:21 < PaulFertser> Or this one https://mmt.zp.ua/img/shop/goods/1328.jpg
2020-05-17T23:12:51 < Steffanx> So did you ever fix your NAS/external disk/storage issue PaulFertser?
2020-05-17T23:13:04 < Steffanx> Replaced the psu and done?
2020-05-17T23:13:07 < PaulFertser> And here's how radiating antennas look like: https://mmt.zp.ua/img/shop/goods/3502.jpg
2020-05-17T23:13:15 < Steffanx> oh you're still in lock down ofcourse.
2020-05-17T23:13:47 < PaulFertser> Steffanx: yep, it was just that, my father attached ATX PSU instead of the china 12+5 V crap I had (that worked for more than a year)
2020-05-17T23:17:19 < PaulFertser> One of those antennas is supposed to go up an arse, 21 mm diameter according to https://mmt.zp.ua/shop/med-uchrezhdeniyam/fisio/el_polya/smv/good_3502.html
2020-05-17T23:18:07 < Cracki> lol
2020-05-17T23:18:40 < Cracki> the anal probes they had in the OR "torture chamber" (where all the fixtures are) were frightening
2020-05-17T23:18:58 < Cracki> oh, vaginal too
2020-05-17T23:23:38 < PaulFertser> https://samarpanphysioclinic.com/2019/11/13/short-wave-diathermy-swd-details/ and there's SWD research available from "pubmed".
2020-05-17T23:24:42 < PaulFertser> E.g. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6856911/ . So nothing really soviet-specific.
2020-05-17T23:28:03 < qyx> PaulFertser: the device.. is it from 1970?
2020-05-17T23:28:14 < qyx> or some more recent stuff
2020-05-17T23:28:37 < PaulFertser> qyx: unfortunately, I didn't have a chance to disassemble it, was just reading the user manual during the exposition.
2020-05-17T23:29:24 < PaulFertser> qyx: I guess they're currently in production. Not sure how modern the internals are.
2020-05-17T23:30:55 < PaulFertser> Cracki: re history, I guess Machiavelli's "The Prince" is still relevant and adding russian history knowledge wouldn't add much to it.
2020-05-17T23:32:15 < Cracki> hmmm thx for the recommendation
2020-05-17T23:33:04 < Cracki> anything a westerner could read that's written by a russian/soviet about stalin's time? I hear the same shit is now going on today in the west, but nobody sees the parallels
2020-05-17T23:33:17 < PaulFertser> "Joseph Stalin read The Prince and annotated his own copy." heh
2020-05-17T23:33:23 < Cracki> (I don't trust westerners to write honestly about communism)
2020-05-17T23:33:27 < Cracki> lol
2020-05-17T23:33:36 < Cracki> ok that's enough of an endorsement
2020-05-17T23:35:19 < Thorn> there's a shit ton of modern laser and magnetic treatment devices being made here, most or all being bullshit and snake oil of course
2020-05-17T23:35:22 < PaulFertser> Cracki: https://en.wikipedia.org/wiki/The_First_Circle is even relevant to the channel.
2020-05-17T23:35:59 < Cracki> ah, that name sounds familiar
2020-05-17T23:37:02 < PaulFertser> https://en.wikipedia.org/wiki/The_Gulag_Archipelago would be too boring I guess, but I haven't read this so can't tell for sure
2020-05-17T23:37:54 < Cracki> excellent

2020-05-17T23:41:58 < PaulFertser> Cracki: If you're into literature you might consider https://en.wikipedia.org/wiki/We_(novel) (was an inspiration for 1984 and probably brave new world) and https://en.wikipedia.org/wiki/The_Foundation_Pit
2020-05-17T23:42:55 < Cracki> not "into literature" but I loved to read some types of novel and right now I'm most interested in knowing what's to come and how to save my hide

2020-05-17T23:44:21 < PaulFertser> BTW, movie recommendation: https://en.wikipedia.org/wiki/Kin-dza-dza! . Late-late-soviet, very unorthodox, smart, funny moving.
2020-05-17T23:44:49 < PaulFertser> Thorn++
2020-05-17T23:46:23 < PaulFertser> I wonder if hitler was literally jailing the scientists and engineers in similar "research prisons" too.
2020-05-17T23:47:09 < Cracki> if hogan's heroes is to be believed, they certainly got their "shadows" but rarely imprisonment
2020-05-17T23:47:51 < Cracki> research prisons sound like a recipe for disaster
2020-05-17T23:48:06 < Cracki> either they stall, or they deliver faulty results, or they die
2020-05-17T23:48:31 < PaulFertser> The First Circle is literally about forced labour for engineers. And it was supposedly quite efficient.
2020-05-17T23:49:03 < PaulFertser> Because many were preferring that to going to Kolyma.
2020-05-17T23:49:23 < Cracki> i can see the appeal
2020-05-17T23:49:50 < Cracki> the principle is to threaten people with even worse consequences so they'll swallow the lesser evil

--- Day changed Mon May 18 2020
2020-05-18T00:00:29 < karlp> we used a metal lathe and a wood lathe in my shop classes, aged 14-15 none of it was cnc though. hell, I still did manual drafting in that course
2020-05-18T00:01:25 < karlp> jadew: we did dustpans from sheet metal too. that was a 13yo task, 14-15 yo we made toolboxes.
2020-05-18T00:02:00 < jadew> nice
2020-05-18T00:02:05 < karlp> get all teh bits, cutting, magnabending, wire rolled edges, beaten edges, manual flame lead soldering, spot welding and riveting.
2020-05-18T00:02:25 < PaulFertser> "Thirty years after its original release, Little White Lies magazine described Kin-dza-dza! as "Mad Max meets Monty Python by way of Tarkovsky" "
2020-05-18T00:02:30 < jadew> oh, right, those classes are when I did technical drawing for the first time
2020-05-18T00:03:10 < jadew> do kids these days still do this tho?
2020-05-18T00:07:21 < karlp> at least at my high shool, I thikn technical drafting finished ~2 years after me.
2020-05-18T00:07:47 < karlp> that was also when cooking and sewing were added, 
2020-05-18T00:08:13 < karlp> still kinda shocked that you can't cook jade, you're a grown up!
2020-05-18T00:08:34 < karlp> but I probably shouldn't be Iguess, met enough men who can't.
2020-05-18T00:08:47 < jadew> heh, yeah, it sucks
2020-05-18T00:09:33 < karlp> I cooked probably 80% of the time before the kids were born, but working hours has meant my wife cooks probably 80% now, I sure as shit didn't marry her to get a cook :)
2020-05-18T00:09:49 < zyp> «can't» sounds more like «unwilling to try» to me
2020-05-18T00:10:00 < jadew> before I got married, I was only eating out or ordering food, lived like that for almost 10 years
2020-05-18T00:10:20 < jadew> I tried to cook several times, but didn't like the result... didn't compare with anything I had before
2020-05-18T00:11:45 < jadew> when I moved out of one of my last apartments, where I was living alone, I had to get someone to clean the kitchen, because I didn't step in there for several years and it was all dusty and horrific
2020-05-18T00:12:34 < karlp> zyp: re cant, yeah :)
2020-05-18T00:12:36 < jadew> this is also one of the reasons I can't sleep at night, I got used to eat at 3 am
2020-05-18T00:12:59 < karlp> a guy I knew in the states couldn't cook, had just earnt enough since they finished uni to just eat out all the time.
2020-05-18T00:13:04 < jadew> because I was finishing work at midnight and would then leave to eat at a restaurant
2020-05-18T00:13:09 < zyp> in norway, both eating out and takeout is pretty expensive, not really an option to do that for every meal
2020-05-18T00:13:33 < karlp> I tought him to cook, was like one ingredient at at ime, was kinda funny watching him be so excited at "man, I can cook a steak too!"
2020-05-18T00:13:37 < karlp> and onions!
2020-05-18T00:13:42 < karlp> and man, paprika is pretty good!
2020-05-18T00:13:48 < englishman> karlp: https://i.imgur.com/XTSA7OP.jpg
2020-05-18T00:13:53 < karlp> over a few years he actyualyl built up to actually cooking meals :)
2020-05-18T00:14:11 < karlp> englishman: lovely, even if the cat's in the way
2020-05-18T00:15:40 < Steffanx> what jadew.. you never got into the kitchen? Even when i dont cook i get there VERY often.
2020-05-18T00:15:59 < jadew> Steffanx, the fridge stopped working at some point and I didn't bother to fix it
2020-05-18T00:16:09 < jadew> after that, I didn't have much of a reason to go there
2020-05-18T00:16:29 < Steffanx> cleaning it is a good reason.
2020-05-18T00:16:35 < jadew> in the summer I would buy ice and keep my drinks cool in one of those thermally isolated boxes
2020-05-18T00:16:46 < karlp> in other news, mikrotik hw seems nice, works, but can't say I'm real thrilled with the web ui for config
2020-05-18T00:16:57 < zyp> karlp, I fucking told you :)
2020-05-18T00:17:02 < karlp> you did :)
2020-05-18T00:17:13 < Steffanx> muhahaha
2020-05-18T00:17:34 < karlp> I've got it all working, but.... really?! this is how they expect people to work? in 2020?
2020-05-18T00:17:54 < karlp> no helpers for anything, just "here's a form exposing raw iptables, every single fucking option"
2020-05-18T00:18:31 < karlp> wanted to have dhcp names registered in dns, got this madness: https://wiki.mikrotik.com/wiki/Setting_static_DNS_record_for_each_DHCP_lease ... fuck. no.
2020-05-18T00:19:00 < zyp> hahaha
2020-05-18T00:19:33 < karlp> so, tempting to just put openwrt on it :) at least the main router one.
2020-05-18T00:21:00 < PaulFertser> karlp: how about mikrotik coloured fancy prompt?
2020-05-18T00:21:27 < karlp> I'm not at all interested in using a cli to configure what I consider to be very basic router options
2020-05-18T00:22:25 < PaulFertser> Why did you even try though instead of installing OpenWrt right away? Just for the curiousity's sake?
2020-05-18T00:22:39 < karlp> wnated to see what the vendor wifi performance was
2020-05-18T00:22:59 < karlp> feel a little burnt by putting openwrt on a mt7621 that ended up with pretty shitty wifi perf
2020-05-18T00:23:20 < karlp> and this was for the new house, just wanted wifi to work and require less thought and apologies to the family
2020-05-18T00:26:16 < PaulFertser> karlp: isn't it "if you do not want OpenWrt then here's your 1G Ethernet, install whatever you want for yourself"?
2020-05-18T00:26:59 < karlp> sorry?
2020-05-18T00:29:05 < PaulFertser> karlp: why can't you tell your family that if they're unhappy with you taking time to configure OpenWrt properly they can have their own gear and configure it however they want?
2020-05-18T00:29:07 < zyp> karlp, what do you consider «pretty shitty wifi perf»?
2020-05-18T00:30:38 < karlp> old house, 77m2, virtualyl 0 reception in the bedroom.
2020-05-18T00:30:54 < karlp> 2.4gig on ramips wifi is a known shithole apparently
2020-05-18T00:31:55 < zyp> huh, apparently I've forgotten about getting a speed upgrade
2020-05-18T00:32:08 < zyp> https://www.speedtest.net/result/a/6081854626.png <- this is what my phone pulls over wifi here
2020-05-18T00:32:28 < zyp> thought I only had 150/150
2020-05-18T00:34:15 < karlp> what wifi is that? ubnt?
2020-05-18T00:34:51 < zyp> yeah, uap-ac-lite

2020-05-18T00:42:15 < zyp> although to be fair, bgn would be plenty for upstairs wifi too
2020-05-18T00:43:02 < zyp> hadn't it been for the metallized layer in the floor blocking wifi signals, I would probably still have been using only the old uap
2020-05-18T00:44:25 < zyp> when I eventually replace the old uap, it's more likely it'll happen because I want to switch to something that'll run on standard poe rather than passive poe than actually needing a speed improvement :p
2020-05-18T00:56:03 < Steffanx> Your uap-ac-lite does right?
2020-05-18T00:56:25 < Steffanx> I recall the earlier version of that one also had passive POE
2020-05-18T00:56:59 < zyp> it does both, I'm currently running it from standard poe

2020-05-18T00:57:59 < catphish> i just wrote some code to write 1kB of data to flash, it takes 2 seconds, did i do somehting dumb? surely it's no supposed to be that slow https://paste.ubuntu.com/p/n7KQSRY7sQ/
2020-05-18T00:58:08 < zyp> https://bin.jvnv.net/file/GtfZh.jpg <- downstairs AP is port 14, upstairs AP is port 15
2020-05-18T01:05:48 < catphish> just checked the datasheet, erasing a 128kB flash block takes 2s :(
2020-05-18T01:07:41 < catphish> really it only needs to be erased once every 128 writes, but then i have to maintain a bitmap of used 1k blocks, and do i really care? :)
2020-05-18T01:08:37 < catphish> also, why would the erase parallelism be configurable, why not always erase 32 bits at a time i wonder
2020-05-18T01:09:04 < catphish> certainly seems worth updating my code to erase and write 32 bit blocks, should double the speed
2020-05-18T01:16:35 < aandrew> zyp: nice, I just picked up an ER-X

2020-05-18T01:19:41 < aandrew> I don't plan on doing a lot *on* the router, just basically taking care of DHCP and QoS. I'm playing with the traffic classification but it doesn't seem all that useful
2020-05-18T01:20:09 < aandrew> being able to quickly identify a greedy IP is nice though

2020-05-18T02:15:31 < Laurenceb> use a cheap chinesium solar water heater combined with large plastic drums to store the water for 24hour heating
2020-05-18T02:15:57 < LoneElf> Cracki, you speaking to me?
2020-05-18T02:16:14 < Cracki> you decide
2020-05-18T02:16:16 < englishman> good idea Laurenceb
2020-05-18T02:16:24 < englishman> big underground tanks
2020-05-18T02:16:43 < englishman> with a daylight-trigger for the solar pumps
2020-05-18T02:16:59 < Laurenceb> or just in the corner of the greenhouse with insulation boards around
2020-05-18T02:17:52 < LoneElf> Cracki, if you're speaking to me, I've given about as much information as I can. For some reason the "Makefile" option is grayed out in the dropdown many of STM32CubeMX.
2020-05-18T02:19:15 < englishman> Laurenceb, how much water?
2020-05-18T02:19:21 < Cracki> curious. I never used it to generate a makefile but I don't see why it would do that. see any config options around there that sound like it needs to find a compiler or something?
2020-05-18T02:19:37 < Cracki> perhaps it's checking to find gcc for arm none eabi
2020-05-18T02:20:13 < Laurenceb> englishman: perhaps 75l/m^2
2020-05-18T02:20:15 < Cracki> https://hackaday.com/2017/07/15/stm32cubemx-makes-makefiles/
2020-05-18T02:20:19 < Cracki> BINPATH they say
2020-05-18T02:20:31 < LoneElf> Cracki, oddly enough for a STM32F4 board selection I am able to select Makefile.... I mean, I guess it's not a thing that I actually _need_. But it would be useful. I actually plan on using gn/ninja.
2020-05-18T02:20:32 < englishman> that's not much, cool
2020-05-18T02:20:41 < Cracki> look through cubemx system menu for help option, scan their documentation
2020-05-18T02:21:05 < Laurenceb> https://www.ebay.co.uk/i/133343624138?chn=ps&norover=1&mkevt=1&mkrid=710-134428-41853-0&mkcid=2&itemid=133343624138&targetid=879043638628&device=c&mktype=pla&googleloc=9046557&poi=&campaignid=9455575137&mkgroupid=94880575894&rlsatarget=pla-879043638628&abcId=1139576&merchantid=6995734&gclid=EAIaIQobChMI0s6B34S86QIVme3tCh38gwSaEAkYAiABEgKxOfD_BwE
2020-05-18T02:21:11 < Laurenceb> argg url hell
2020-05-18T02:21:18 < Cracki> so they _don't_ support a specific stm32 series...
2020-05-18T02:21:33 < Cracki> I'd send them a bug report. maybe ask first in the support forum.
2020-05-18T02:21:52 < LoneElf> Cracki, that appears it may be the case. I can't seem to find any information about it online, but it seems it _could_ be the case.
2020-05-18T02:21:57 < LoneElf> Cracki, thanks.
2020-05-18T02:22:17 < englishman> Laurenceb: how much surface area for the solar heater
2020-05-18T02:22:24 < Laurenceb> https://www.deltacontainers.com/reconditioned-keg-220ltr.html
2020-05-18T02:22:27 < englishman> probably more than the greenhouse space
2020-05-18T02:22:29 < Laurenceb> not too expensive
2020-05-18T02:22:47 < Cracki> wonder why they'd deny you makefiles for H7. any other option would use gcc too.
2020-05-18T02:23:10 < LoneElf> Cracki, indeed.
2020-05-18T02:23:43 < englishman> well I'd probably find a single large tank or make one from cheap steel
2020-05-18T02:23:58 < Cracki> hm, I might convert to makefiles myself... truestudio/cubeide feels slow as fuck, and either it's just mine or it is really that dumb, but the refactoring options feel severely lacking

2020-05-18T02:27:22 < Laurenceb> not bad price at all

2020-05-18T02:28:39 < Laurenceb> yeah you are gunna need a similar area of solar collector
2020-05-18T02:28:43 < Laurenceb> maybe a little less
2020-05-18T02:28:56 < englishman> those tubes don't transport well
2020-05-18T02:29:07 < englishman> there's a big tube company just down the road from me
2020-05-18T02:29:13 < englishman> they probably already have a product line
2020-05-18T02:29:25 < englishman> and as my uncle owns it he should cut me a deal
2020-05-18T02:29:53 < Laurenceb> oh cool
2020-05-18T02:30:14 < Laurenceb> so maybe as little as $40/m^2 for whole heating system at china prices
2020-05-18T02:30:56 < englishman> easy to expand if more energy is needed, too
2020-05-18T02:31:40 < Laurenceb> hah at uk electricity prices it would pay for itself in less than 6 months
2020-05-18T02:31:54 < englishman> nice
2020-05-18T02:32:04 < englishman> time to install solar water on your house?
2020-05-18T02:32:35 < Laurenceb> yeah I will at some point...
2020-05-18T02:32:53 < Laurenceb> pain to integrate with a combination condenser boiler tho, thats the problem
2020-05-18T02:33:06 < Laurenceb> weed farm amirite?
2020-05-18T02:33:29 < englishman> haha have you seen the state of weed stocks.
2020-05-18T02:33:41 < englishman> Aurora is down like 92% yoy
2020-05-18T02:34:02 < englishman> food is expensive enough that it makes sense to grow.
2020-05-18T02:34:28 < Laurenceb> yeah I've been planting some in my garden
2020-05-18T02:36:01 < englishman> this one install I saw used large flat plastic tanks
2020-05-18T02:36:15 < englishman> tube seems unnecessary, and it has to be round
2020-05-18T02:36:29 < Laurenceb> https://imagebin.ca/v/5MslNdog0eT0
2020-05-18T02:36:35 < Laurenceb> diggin it up
2020-05-18T02:37:24 < englishman> hmm the vacuum tubes tho.
2020-05-18T02:40:27 < Laurenceb> vacuum tubes are nice as they give you >40C even in cloudy weather
2020-05-18T02:40:53 < sync> englishman: I did the calcs and here it's not worth growing your own stuff
2020-05-18T02:41:08 < englishman> weed or veggies
2020-05-18T02:41:38 < sync> yes
2020-05-18T02:42:56 < Laurenceb> hmm actually that was the price for raw tubes, with thermosyphon it gets more expensive
2020-05-18T02:43:19 < Laurenceb> but you could just pump water/glycol through tubes with an o-ring at either end
2020-05-18T02:45:00 < Laurenceb> it just wouldnt have a failsafe mode, so could spew steam everywhere in summer
2020-05-18T02:45:09 < Laurenceb> if the pumps broke
2020-05-18T02:51:23 < sync> it only needs to be quite pressure resistant
2020-05-18T02:51:31 < sync> then it'll just get blazing hot

2020-05-18T02:54:33 < Laurenceb> quite a bit more expensive with the heat pipe fitted
2020-05-18T02:55:37 < englishman> https://hydrosolar.ca/collections/vacuum-tube-solar-collectors/products/xianke-xkph58-srcc-certified-evacuated-tube-solar-collector?variant=7021173932093
2020-05-18T02:55:41 < Laurenceb> about $60/m^2 with the tank and pipes maybe
2020-05-18T02:57:04 < englishman> yeah those china prices are crazy low
2020-05-18T02:57:23 < englishman> and boat shipping is crazy cheap
2020-05-18T02:59:43 < Laurenceb> yeah that hydrosolar panel is about twice china price

2020-05-18T03:15:40 < Laurenceb> annoyingly I think you need the heat pipes unless you want to try a half baked (and half priceed) design
2020-05-18T03:16:12 -!- upgrdman [~upgrdman@blender/artist/upgrdman] has joined ##stm32
2020-05-18T03:16:37 < Laurenceb> for half baked I might try a water/calcium chloride loop to the panels, with copper coil heat exchanger to the storage water, and a header tank
2020-05-18T03:16:59 < Laurenceb> if it overheats it will boil off through the header tank, but you wont lose the antifreeze
2020-05-18T03:17:19 < Laurenceb> a ballcock valve could be used to keep it topped up
2020-05-18T03:18:34 < Laurenceb> like an oldschool uk heating system
2020-05-18T03:18:54 < Laurenceb> >leave the boiler on too long and steam starts venting out of the cupboard

2020-05-18T03:21:49 < Laurenceb> >sauna mode
2020-05-18T03:22:11 < kakimir> sauna
2020-05-18T03:22:19 < kakimir> you need to sauna
2020-05-18T03:22:21 < Laurenceb> have a greenhouse/sauna selector button
2020-05-18T03:22:38 < kakimir> build real sauna
2020-05-18T03:24:06 < Laurenceb> I think a solar heated arctic greenhouse is more useful than a solar sauna
2020-05-18T03:24:43 < kakimir> no
2020-05-18T03:24:58 < kakimir> sauna you heat with burning wood or nuclear energy
2020-05-18T03:25:14 < Laurenceb> >or nuclear energy

2020-05-18T03:25:47 < Laurenceb> maybe my uncle could help
2020-05-18T03:25:55 < kakimir> plutonium stove would be nice
2020-05-18T03:26:12 < kakimir> red hot pellets there between the stones
2020-05-18T03:27:37 < kakimir> https://upload.wikimedia.org/wikipedia/commons/7/71/Plutonium_pellet.jpg
2020-05-18T03:37:47 < aandrew> bleh I can't seem to get more than about 160Mbps with the ER-X when a single smartqueue is enabled. Mind you with NO QoS enabled it's not any better. hwnat is enabled too
2020-05-18T03:39:40 < kakimir> yes
2020-05-18T03:39:51 < englishman> yes Laurenceb i agree the vacuum tubes are the way to go
2020-05-18T03:46:36 < englishman> looks like about $0.50 or less per watt
2020-05-18T04:10:47 < Laurenceb> kakimir: that photo is kind of fake
2020-05-18T04:11:08 < Laurenceb> they covered it with insulation before taking the photo, the pellets dont heat that quickly

2020-05-18T10:38:10 < PaulFertser> btw, OpenWrt has a much more advanced QoS called SQM. People say it works wonders.
2020-05-18T10:49:40 < zyp> catphish, er-lite is more beefy hardware than er-x
2020-05-18T10:50:30 < zyp> er-x is pretty much switch hardware forced to do routing
2020-05-18T10:50:48 < catphish> that's true
2020-05-18T10:51:11 < catphish> for basic functionality they both do fine, but er-x may be lacking in some areas
2020-05-18T10:51:56 < catphish> maybe just upgrade to an MX204, we use those too :)
2020-05-18T10:52:05 < zyp> I've got an er-x at work to connect various subnets, which it does nicely because I don't really need a lot of performance
2020-05-18T10:52:18 < catphish> it can route at a gigabit though
2020-05-18T10:52:27 < zyp> can it?
2020-05-18T10:52:30 < catphish> the problem only comes when you start enabling features
2020-05-18T10:52:43  * catphish checks
2020-05-18T10:53:21 < catphish> yex, ER-X can do 1Gbps
2020-05-18T10:53:31 < zyp> routing, not just switching?
2020-05-18T10:53:43 < catphish> yes, routing
2020-05-18T10:55:06 < catphish> https://www.ui.com/edgemax/comparison/
2020-05-18T10:56:03 < catphish> but... it's not as beefy as the er-lite, it can't do simultaneous gigabit on every port, and (much like any edgerouter) enabling some features will dramatically reduce that number
2020-05-18T10:56:17 < zyp> ah, 1 Gb/s combined, right
2020-05-18T10:56:28 < catphish> but yes, for basic routing, it *can* do 1Gbps
2020-05-18T10:56:29 < zyp> because internal cpu port is also 1 Gb/s
2020-05-18T10:56:59 < zyp> so it's essentially a 6-port switch
2020-05-18T10:57:03 < catphish> it's not clear to me if it uses its more powerful cpu for all routing
2020-05-18T10:57:13 < catphish> i suspect not, but not certain
2020-05-18T10:57:53 < zyp> look at the numbers
2020-05-18T10:58:20 < zyp> ER-4 can do 4 Gb/s routing, because it has four ports, so you can't feed it more than 4x1Gb/s
2020-05-18T10:58:33 < zyp> but ER-X has five ports and is still limited to 1 Gb/s
2020-05-18T10:58:43 < catphish> that certainly implies it's cpu-routing
2020-05-18T10:59:30 < zyp> not necessarily cpu, but it's limited by the 1 Gb/s interface towards the router
2020-05-18T10:59:51 < catphish> however... i know with some certainty that the traffic doesn't go through the full linux network stack
2020-05-18T11:00:03 < zyp> the ERPoe-5 (that I have) is limited to 3 Gb/s despite having five ports
2020-05-18T11:00:14 < zyp> it has a three port switch on one port, and two dedicated routing ports
2020-05-18T11:00:21 < catphish> so my guess is that they have a router-cpu-asic, but only on one port of the switch
2020-05-18T11:00:23 < effractur> Na ER-X is full software
2020-05-18T11:00:49 < effractur> 260 kpps for 64-byte packets
2020-05-18T11:00:51 < catphish> effractur: yes and no, it definitely has some hardware functionality, that may be inside the cpu, but it exists
2020-05-18T11:01:18 < effractur> i mean there is some l2 switch thingy in there
2020-05-18T11:01:21 < catphish> effractur: the comparson i just linked to says it can do 1.4Mpps
2020-05-18T11:01:35 < catphish> it's "fast-path" whatever that is
2020-05-18T11:02:06 < effractur> strange the 260 number is from the datasheet
2020-05-18T11:02:17 < catphish> i'm looking at https://www.ui.com/edgemax/comparison/
2020-05-18T11:02:36 < catphish> bear in mind that they added more hardware offload to the er-x after launch
2020-05-18T11:02:40 < catphish> so maybe it's not documented everywhere
2020-05-18T11:03:21 < catphish> i heard at the time that fast-path wasn't ready at launch so they just shipped anyway with software routing
2020-05-18T11:03:43 < effractur> that explains it then
2020-05-18T11:04:09 < effractur> the SoC is MT7621
2020-05-18T11:04:17 < catphish> but i've personally observed the hardware offload in action, the first few packets of a flow through the router show up in tcpdump, then they just vanish
2020-05-18T11:04:32 < effractur> and that does NAT offloading it seems
2020-05-18T11:04:39 < effractur> so cpu can program the flows into the soc
2020-05-18T11:05:05 < catphish> right, that's the idea, so it's offloaded per-flow
2020-05-18T11:05:46 < catphish> this also has the benefit that it can offload traffic the asic supports (basic routing, nat) but not offload stuff that it doesn't know how to handle
2020-05-18T11:06:53 < catphish> unfortunately, i had to disable it on mine because the wireguard package i use doesn't understand this concept and it offloads traffic that needs to be decryted by the kernel throwing it into a black hole
2020-05-18T11:11:11 < zyp> haha
2020-05-18T11:11:44 < zyp> have they added official support for wireguard yet?
2020-05-18T11:15:40 < catphish> not that i know of, i really hope it comes now wg is in the upstream kernsl
2020-05-18T11:15:43 < catphish> *kernel
2020-05-18T11:15:53 < catphish> but the unofficial package works great for me
2020-05-18T11:16:45 < catphish> i'm wondering when it becomes appropriate to take antibiotics for an infection
2020-05-18T11:17:12 < Cracki> bacterial infection?
2020-05-18T11:17:19 < catphish> obviously
2020-05-18T11:17:32 < Cracki> when and for as long as the doctor prescribes them? :P
2020-05-18T11:17:52 < catphish> i get really irritated by insect bites, i scratch them, they get infected, sometimes it gets bad
2020-05-18T11:18:11 < catphish> but it's never clear how bad such a thing should be before you ask for treatmnt
2020-05-18T11:18:11 < Cracki> I don't think you have to give your immune system a chance, you can hit it right away
2020-05-18T11:18:32 < Cracki> if it's just on the skin, there are other remedies
2020-05-18T11:19:26 < catphish> i suppose a doctor is best placed to decide, but being british, one doesn't want to waste their time, and it's only on the surface for now
2020-05-18T11:19:34 < Cracki> I guess lots of things fall under "antibiotics" but the penicillin-like stuff you take is precious
2020-05-18T11:19:51 < Cracki> pour in some scotch maybe
2020-05-18T11:20:19 < catphish> lol i use this stuff a lot https://en.wikipedia.org/wiki/TCP_(antiseptic)
2020-05-18T11:20:29 < Cracki> looks good
2020-05-18T11:21:38 < Cracki> >harmful to cats
2020-05-18T11:21:46 < Cracki> hope you're more phish than cat
2020-05-18T11:32:54 < Cracki> wow that's a sensitive sensor http://www.camera-module.com/product/2mpcameramodule/hdr-starlight-ull-camera-module-omnivision-os02c10.html

2020-05-18T15:00:23 < Steffanx> Hi usb pros. Question: if I have a his joystick. And one does not touch the joystick. Do I send a report with xyz at the same value or do I keep quiet? Is there any "rule" for this?
2020-05-18T15:00:41 < Steffanx> Not his joystick, but a HID. Lol
2020-05-18T15:02:38 < jpa-> for a moment i was worried you had fallen for Tectu's joystick again - despite the corona restrictions
2020-05-18T15:02:58 < Steffanx> Sorry. You're still the one, jpa- 
2020-05-18T15:04:19 < jpa-> http://www.usbmadesimple.co.uk/ums_5.htm  "You may notice that there was a nearly 3 second gap before the mouse was first moved. In the meantime there were still regular interrupt IN transactions, which were NAKed by the device, as it had nothing to report."   makes it sound like you don't report if nothing changes
2020-05-18T15:07:10 < Steffanx> windows does not really care btw, but the nvidia in-game overlay messes with it.
2020-05-18T15:07:40 < Steffanx> As soon as you enable that it will reset windows idle timeout each time a report is received.
2020-05-18T15:08:06 < Steffanx> *geforce experience in game overlay.

2020-05-18T15:22:46 < Steffanx> Seems to be a common issue with joysticks/gamepads and whatever in combination with this overlay.

2020-05-18T16:19:47 < Steffanx> I tried the naking. the nvidia overlay seems much happier with that.
2020-05-18T16:35:48 < Thorn> does the joystick report relative or absolute coordinates btw?
2020-05-18T16:36:05 < zyp> you can do either for that as well
2020-05-18T16:36:29 < Thorn> >usb, where you send info even if you don't send info
2020-05-18T16:37:14 < zyp> for each value in a hid report descriptor, you also declare whether it's an absolute or relative value
2020-05-18T16:39:58 < Thorn> what's the deal with pcb mount cr2032 batteries like https://www.tme.eu/html/EN/lithium-battery-cr2032-for-pcb-mounting/ramka_9790_EN_pelny.html ? do you use them when you anticipate no need to replace them during the lifetime of your device?

2020-05-18T17:17:38 < Laurenceb> I ran into similar issues
2020-05-18T17:17:43 < Laurenceb> also its a cpu killer
2020-05-18T17:17:50 < mawk> restore from backup every hour
2020-05-18T17:17:52 < mawk> problem solved
2020-05-18T17:18:04 < Laurenceb> well... if you have been asked to input data from 2khz sensors in real time
2020-05-18T17:18:10 < Laurenceb> which is stupid to start with
2020-05-18T17:18:34 < Laurenceb> I used rf64 with bittorrent to the server, then xeon server to load it into the database
2020-05-18T17:19:05 < Laurenceb> rf64 can handle >4GB and has all the riff tags that wav has
2020-05-18T17:20:22 < Laurenceb> flac is probably the more pro way
2020-05-18T17:20:55 < Laurenceb> even the xeon couldnt load wambulance data in real time
2020-05-18T17:20:58 < Cracki> corrupted index or what is that
2020-05-18T17:21:07 < englishman> storing sequentially named PNG files in a NTFS share is probably more reliable
2020-05-18T17:21:11 < Cracki> people say backup+restore fixes the gaps. how the fuck can they fuck that up
2020-05-18T17:21:33 < Cracki> flac, eh, that just saves half the storage
2020-05-18T17:21:44 < Laurenceb> good enough
2020-05-18T17:22:00 < Laurenceb> dunno how good its support for weird tags is
2020-05-18T17:22:18 < Laurenceb> I abused them for config and metadata
2020-05-18T17:22:32 < Thorn> xc7z020-1clg400c on aliexpress ranges from $32 to ~$80, are the cheap ones legit

2020-05-18T18:46:35 < zyp> dongs, zfs includes a raid layer
2020-05-18T18:46:35 < dongs> that will eat shit and die
2020-05-18T18:46:55 < Cracki> didn't zfs come out of sun microsystems or something
2020-05-18T18:46:55 < karlp> this is intended as a vm server, and some of the vms are kinda important.
2020-05-18T18:47:09 < zyp> karlp, are those ssds?
2020-05-18T18:47:09 < dongs> karlp: why not just run esxi with its own filesystem that works
2020-05-18T18:47:21 < dongs> on top of proper hardware raid
2020-05-18T18:47:27 < zyp> karlp, or really old drives?
2020-05-18T18:47:36 < karlp> zyp: oh no, very very old spinning rust, hence the desire to have some sort of fail protection, instead of just throwing it all into an lvm pool
2020-05-18T18:48:04 < zyp> heh, well, zfs should do
2020-05-18T18:48:15 < karlp> dongs: just goign to use kvm like I have been using, just looking at imrpoving the underlyinh storage
2020-05-18T18:48:23 < dongs> ah good luck
2020-05-18T18:48:26 < dongs> i thought you said important
2020-05-18T18:48:28 < karlp> is 2x600 raidz1 still safe fora s ingle disk failure?
2020-05-18T18:48:30 < dongs> then you turn around and run lunix
2020-05-18T18:48:31 < dongs> but yea ok
2020-05-18T18:48:37 < karlp> well, pseudo important, sure
2020-05-18T18:48:46 < Laurenceb> >muh spinning rust
2020-05-18T18:48:51 < Laurenceb> redditor spotted
2020-05-18T18:48:59 < zyp> karlp, how about just putting the two 600G drives in a mirror set?
2020-05-18T18:49:25 < karlp> I guess, 600gig is probably plenty still :)
2020-05-18T18:50:11 < zyp> 2x600G mirrored and 3x300G raidz1 both gives you 600G net and protects against one drive failure
2020-05-18T18:50:47 < karlp> so yeah, 2 disks in raidz1 doesn't actualyl give you disk fail protection?
2020-05-18T18:50:54 < bitmask> think a silver base (really just grey with a little bit of sparkle) will look good with copper letters on top?
2020-05-18T18:50:54 < zyp> but the mirror set is probably faster, and one failure in two drives is less likely than one failure in three drives
2020-05-18T18:51:21 < zyp> why would you want parity raid over two drives instead of a mirror set?
2020-05-18T18:51:27 < bitmask> I'm very limited to base color and I want letters to be copper
2020-05-18T18:51:35 < bitmask> I only really have black white blue and silver
2020-05-18T18:51:46 < karlp> because I wanted to have to think less, and "just always use this setup" :)
2020-05-18T18:52:03 < zyp> zfs can do both
2020-05-18T18:55:25 < Laurenceb> I was developing a car project that has since been cancelled that boasted 2,500mi range with a suitcase sized battery that only took 120 seconds to charge using a hand cranked generator and was made of 100% recyclable and compostable food-grade materials.

2020-05-19T00:33:13 < zyp> qyx, more numbers sanity check; so backplane to front panel is 85.5mm, pcie socket is 3.4mm from pcb to slot bottom, and card is 8.4mm from bottom to notch
2020-05-19T00:33:51 < zyp> giving me a max depth of 82.1 and overall depth of 73.7
2020-05-19T00:34:13 < zyp> minus any margin between card and front panel, do I need that?
2020-05-19T00:34:31 < qyx> yes, 2.54mm afaik
2020-05-19T00:34:40 < zyp> why?
2020-05-19T00:35:00 < qyx> otherwise the conenctor would not be fully inserted
2020-05-19T00:35:08 < zyp> how so?
2020-05-19T00:35:32 < qyx> the card would be "pulled" by the front panel
2020-05-19T00:35:49 < qyx> the front panel couldn't be pushed more because of front horizontal rails
2020-05-19T00:37:28 < qyx> re: backplane to front panel is 85.5mm, yes

2020-05-19T00:37:49 < qyx> pcie socket is 3.4mm from pcb to slot bottom, yes
2020-05-19T00:37:54 < qyx> (I used 4.0mm)
2020-05-19T00:38:18 < qyx> and card is 8.4mm from bottom to notch, yes
2020-05-19T00:38:49 < qyx> max depth of 82.1, yes
2020-05-19T00:40:05 < qyx> overall depth of 73.7, no, it should be 71.16
2020-05-19T00:40:59 < zyp> that depends how much clearance you want between card and backplane and to me it seems pointless to have more clearance than the 8.4mm notch
2020-05-19T00:41:52 < qyx> oh wait, the other way around, yeah
2020-05-19T00:42:18 < qyx> if you use the numbers according to the standard and doesn't use the clearance in reality, the card cannod be pushed enough
2020-05-19T00:42:29 < qyx> but yes, if you decide there is no clearance, you can do it that way
2020-05-19T00:42:32 < qyx> me dumb
2020-05-19T00:42:46 < qyx> except the L shaped mounting things would not fit
2020-05-19T00:43:10 < zyp> oh, they go between the pcb and front panel?
2020-05-19T00:43:21 < zyp> could always make cutouts for them
2020-05-19T00:44:03 < zyp> hmm
2020-05-19T00:44:14 < qyx> you would need to move the holes too
2020-05-19T00:44:31 < zyp> pcie socket datasheet says 3.4±0.15

2020-05-19T00:45:03 < qyx> yes, I will correct my boards probably in the future
2020-05-19T00:45:20 < qyx> idk why I decided 4.0mm is the right number
2020-05-19T00:46:12 < zyp> I don't understand what you mean by «cannot be pushed enough»
2020-05-19T00:47:34 < qyx> I made my cards with the size accounting for 2.54mm gap
2020-05-19T00:47:46 < qyx> on the first card, I mounted the front panel without any gap
2020-05-19T00:47:57 < qyx> which cause the card to be slightly shorter than required
2020-05-19T00:48:00 < zyp> the front panel is 2mm thick, was that so?
2020-05-19T00:48:18 < qyx> no, 2.54mm between the front panel and the pcb, I mounted it to be 0mm
2020-05-19T00:48:32 < zyp> I mean metal thickness
2020-05-19T00:48:38 < qyx> so the 3.4mm gap between the pcb and the backplane was actually 3.4mm + 2.54mm
2020-05-19T00:49:04 < qyx> hm, actually idk if 2mm or 3mm
2020-05-19T00:49:06 < qyx> I am using 2mm
2020-05-19T00:49:41 < zyp> if the front panel is 2mm thick and I have a clearance of 2.54mm between the panel and the pcb, that's 4.54 mm from pcb edge to front
2020-05-19T00:50:04 < zyp> which seems like a lot for e.g. usb connectors
2020-05-19T00:50:38 < zyp> so I think I'd like to push the pcb all the way up to the panel
2020-05-19T00:50:43 < qyx> it is ok for the molex USB-A connector I am using

2020-05-19T00:53:48 < zyp> and then host gives up and switches to FS which works
2020-05-19T00:55:02 < zyp> yeah, quite likely
2020-05-19T00:55:13 < zyp> datasheet says «USB1.1»
2020-05-19T00:55:40 < qyx> I must have been drunk or what
2020-05-19T00:56:04 < zyp> chirps are probably more robust than the signalling it self so it gets through, but the signal gets too degraded
2020-05-19T00:56:42 < zyp> easy to check; just remove it

2020-05-19T01:00:05 < PaulFertser> qyx: OpenWrt has a kernel patch that makes it automatically used mtd partition named "rootfs" for that but you need to have that kernel option enabled.
2020-05-19T01:00:33 < qyx> the first step would be to define such partition
2020-05-19T01:00:34 < PaulFertser> qyx: CONFIG_MTD_ROOTFS_ROOT_DEV=y
2020-05-19T01:00:42 < qyx> https://downloads.openwrt.org/releases/19.07.3/targets/at91/sama5/
2020-05-19T01:00:52 < qyx> I am using at91-sama5d27_som1_ek-squashfs-zImage
2020-05-19T01:00:52 < zyp> hmm
2020-05-19T01:01:03 < qyx> there is no static config in the device tree
2020-05-19T01:01:11 < PaulFertser> qyx: well, on many mtd targets you define just "firmware" partition and copy both kernel and rootfs there back-to-back, and it's auto-split on boot.
2020-05-19T01:01:14 < zyp> https://bin.jvnv.net/file/NqGx3.png <- maybe barely fits
2020-05-19T01:01:25 < zyp> but…
2020-05-19T01:01:39 < qyx> too close
2020-05-19T01:01:48 < qyx> PaulFertser: you mean catting them together?
2020-05-19T01:02:25 < qyx> uboot uses this bootcmd=sf probe 0; sf read 0x21000000 0xc0000 0x20000; sf read 0x22000000 0xe0000 0x400000; bootz 0x22000000 - 0x21000000
2020-05-19T01:02:26 < PaulFertser> qyx: that's how many targets work by default, yes, to save the space and have dynamically sized kernel partition.
2020-05-19T01:02:41 < qyx> so I assumed 0x400000 is the kernel size
2020-05-19T01:02:55 < qyx> and I flashed the rootfs at 0x4c0000
2020-05-19T01:03:01 < qyx> *0x4e0000
2020-05-19T01:03:18 < qyx> because meh, I cannot find any suitable docs for this target
2020-05-19T01:03:20 < zyp> more realisticly it'll be something like this: https://bin.jvnv.net/file/4zlyT.png
2020-05-19T01:03:21 < PaulFertser> You can read more than the actual size, no harm in doing that.
2020-05-19T01:03:41 < zyp> to leave the front panel open for more stuff
2020-05-19T01:03:57 < zyp> though, I probably only need three usb-c connectors
2020-05-19T01:04:33 < qyx> PaulFertser: so the u-boot only reads ~4meg to get the kernel and then the kernel reads the rest?
2020-05-19T01:04:57 < qyx> ok, I'll try to cat them together and flash again
2020-05-19T01:05:16 < PaulFertser> qyx: no, the kernel is supposed to be at most that size. When it's less, no problem.
2020-05-19T01:05:36 < qyx> yes, you said the same I was thinking :)
2020-05-19T01:06:02 < qyx> theres also this root=/dev/mmcblk0p2
2020-05-19T01:06:14 < qyx> k, just try
2020-05-19T01:07:42 < PaulFertser> qyx: hm, I'm not familiar with your board. If your root= would imply it expects root on the second partition of an SD card (or eMMC).
2020-05-19T01:08:00 < qyx> oh wait what
2020-05-19T01:08:00 < qyx> yes
2020-05-19T01:08:15 < PaulFertser> qyx: so? :)
2020-05-19T01:08:31 < qyx> there are two u-boots
2020-05-19T01:08:38 < qyx> one for mmc, the other one for spiflash
2020-05-19T01:08:52 < qyx> I am curious which one is flashed
2020-05-19T01:09:26 < PaulFertser> qyx: if you're booting from spi nor flash then what I say should apply. Please show serial kernel log, I'll tell what's missing.
2020-05-19T01:09:35 < qyx> hm, the right one, it reads the spi flash to get the thing but passes mmcblk as the root device
2020-05-19T01:09:57 < PaulFertser> qyx: you can change the bootargs env var

2020-05-19T01:12:32 < PaulFertser> qyx: but normal OpenWrt booting from SPI doesn't need any rootfs at all when that config symbol is enabled.

2020-05-19T01:13:20 < qyx> the first problem is probably wrong address of the rootfs
2020-05-19T01:13:31 < qyx> it will take a moment to flash over 115200 baud serial
2020-05-19T01:14:21 < PaulFertser> qyx: without recompiling the kernel you won't get that fancy splitting and rootfs functions. Apparently whoever added support meant it to be used only from SD card.
2020-05-19T01:15:10 < qyx> i am using kernel from the download section fornow
2020-05-19T01:15:16 < PaulFertser> qyx: I recommend booting full OpenWrt from SD. Then you can experiment with fast flashing to SPI as much as you need.
2020-05-19T01:15:40 < qyx> 23:57 < qyx> the only tools i have now are scissors, spoon and a screwdriver
2020-05-19T01:15:46 < qyx> no microSD card in the list :(
2020-05-19T01:16:47 < PaulFertser> qyx: serial log from kernel bootup attempt would give more clues.
2020-05-19T01:17:16 < karlp> yah, some of the targets aren't realyl setup (yet) for spi noor out of the box, sunxi either, as almost none of the common sunxi boards have spi nor
2020-05-19T01:17:24 < qyx> https://paste.jvnv.net/view/iTg2j
2020-05-19T01:17:25 < karlp> so it's all setup for sdcard or emmc only
2020-05-19T01:17:59 < qyx> it is a custom board similar to sama5d27-som1-ek
2020-05-19T01:18:14 < qyx> at least heartbeat is working
2020-05-19T01:18:26 < PaulFertser> qyx: the kernel has no m25p80 driver even
2020-05-19T01:18:40 < PaulFertser> qyx: or the DTS file doesn't specify the device
2020-05-19T01:19:01 < PaulFertser> The driver should be there according to kernel config in upstream.
2020-05-19T01:20:19 < PaulFertser> But you need to tell the kernel that the SPI controller has flash attached and that you use certain partitions there. Since splitters and everything is disabled, make it all fixed size, and use root=/dev/mtd3 (explicit specification) in bootargs.

2020-05-19T05:21:09 < lomas> I am having an issue that the array address is not 16-bit aligned while using SPI module to write data to EEPROM in STM32F0 using HAL. Some says it is a bug in HAL (discussed in here https://community.st.com/s/question/0D50X00009Xkdsn/bug-stm32f0xx-hal-spi-transmit). Any workaround for it ?
2020-05-19T05:29:06 < upgrdman> lomas, i dont use the HAL, but it sounds like the easiest workaround is to ensure your array is 16bit aligned
2020-05-19T05:30:18 < upgrdman> i think gcc has an align keyword
2020-05-19T05:30:35 < upgrdman> oh, "aligned" >> https://gcc.gnu.org/onlinedocs/gcc-3.3/gcc/Type-Attributes.html
2020-05-19T05:32:02 < lomas> Thank you upgrdman. Will go through it and try making modifications. Thanks.

2020-05-19T11:16:43 < catphish> what does usb 3 add that's useful?
2020-05-19T11:17:23 < Thorn> SuperSpeed(tm)
2020-05-19T11:17:29 < dongs> just put a FX3 in front of STM32
2020-05-19T11:18:00 < catphish> superspeed does seem to be the main improvement indeed
2020-05-19T11:18:03 < dongs> and you could prolly push some data to it with FSMC but its not gonna be anywhere nearly fast enough to worth the trouble
2020-05-19T11:18:26 < dongs> can you even saturate USB2 with a F7 or wahtever?
2020-05-19T11:18:33 < dongs> USB2HS that is
2020-05-19T11:18:43 < catphish> high speed is already enough of a hassle, and a ton of bandwidth!
2020-05-19T11:18:43 < zyp> why not?
2020-05-19T11:20:18 < zyp> dongs, on a 32-bit wide data bus, the raw HS bitrate is only 15 MHz
2020-05-19T11:21:40 < zyp> so assuming you've got a source or sink that's fast enough, a half-decent cortex-m should easily be able to push enough data to saturate HS
2020-05-19T11:22:00 < zyp> and that's before you consider that you can do DMA

2020-05-19T12:06:12 < zyp> qyx, slot size comparison: https://bin.jvnv.net/file/eVD8d.png
2020-05-19T12:09:30 < zyp> I'm wondering if I should align it so the 16x gets centered like that, or try to move it further down
2020-05-19T12:10:51 < karlp> qyx: you still stuck with the infinite combinations of getting kernel+rootfs+uboot to all play together?
2020-05-19T12:14:04 < zyp> moving the edge connector as far down as possible would both give me more room to stick shit like that sodimm socket in the upper corner as well as giving me more routing area above the connectors on the backplane
2020-05-19T12:15:30 < qyx> karlp: at91boostrap+uboot+kernel is ok, but this rootfs autodiscovery is meh
2020-05-19T12:15:54 < qyx> also I enabled the factory image
2020-05-19T12:16:12 < qyx> now i get decompression error in uboot
2020-05-19T12:16:37 < qyx> trying to find out how to trigger the damned uboot menuconfig in openwrt
2020-05-19T12:16:55 < qyx> either I am dumb or it is not googleable on the first page
2020-05-19T12:17:07 < karlp> well, it's not magic, it's just if you have this "firmware" partition, and you write it a kernel+squashfs over the end, you get it split into layers
2020-05-19T12:17:10 < karlp> there is no uboot menuconfig
2020-05-19T12:17:20 < karlp> and yes, that's lame
2020-05-19T12:17:40 < karlp> are you trying to use the openwrt built uboot on an sdcard or something?
2020-05-19T12:18:08 < qyx> it builds two, one for sd, the other for spi flash
2020-05-19T12:18:11 < karlp> the openwrt packaging of uboot is "just enough to make sdcards work" and sometimes a few hacks to get out of vendor firmware
2020-05-19T12:18:25 < qyx> I just need to enable lzma in uboot and recompile it
2020-05-19T12:18:31 < qyx> apparetnyl too much hassle
2020-05-19T12:19:16 < karlp> it uses package/boot/uboot-xxxx/ shit for it
2020-05-19T12:19:49 < karlp> and then just calls the xxxx_defconfig for them, I've not seen any way of customizing it.
2020-05-19T12:20:31 < qyx> I though buildroot is a mess
2020-05-19T12:20:35 < karlp> for my spi nor work, I just butil my own uboot, and only had openwrt building kernel+squashfs 
2020-05-19T12:20:39 < qyx> but openwrt looks the same
2020-05-19T12:20:42 < karlp> openwrt is buildroot+yetmore magic
2020-05-19T12:20:55 < karlp> and it's "fine" if you're staying on the reservation
2020-05-19T12:21:13 < karlp> but some of it is, "we only implemented this part, all the rest is completely missing, and undocumented"
2020-05-19T12:21:54 < karlp> why do you need uboot changes?
2020-05-19T12:22:51 < qyx> probably I don't
2020-05-19T12:23:00 < qyx> I mean
2020-05-19T12:23:23 < qyx> it defines uImage for the factory image concatenated with the rootfs stuff
2020-05-19T12:23:32 < qyx> but somehow uboot doesn't recognze its compression format
2020-05-19T12:23:37 < qyx> with zImage it boots
2020-05-19T12:24:09 < qyx> probably the guy never tried it because the default image is ~9MB and the som1-ek1 has only 8MB SPI NOR
2020-05-19T12:25:34 < qyx> it generates this https://paste.jvnv.net/view/hsw0V
2020-05-19T12:28:30 < karlp> very likely.
2020-05-19T12:28:46 < karlp> do you really mean for ubi on spi-nor?
2020-05-19T12:29:18 < karlp> that kinda does sound like someone just copied a few things thinking they were going to support the spi-nor method 
2020-05-19T12:29:42 < karlp> I don't think I've seen ubi on spi-nor, only on nand
2020-05-19T12:30:16 < qyx> me neither
2020-05-19T12:30:25 < qyx> it takes time to discover all that magic
2020-05-19T12:30:38 < qyx> and what you have to change in order to get anything usable

2020-05-19T12:41:47 < karlp> appended dtb is because lots of uboots and other bootloaders _didn't_ have dtbs
2020-05-19T12:42:12 < karlp> but yeah, if you're passing dtb correctly from uboot, no need for appended

2020-05-19T15:48:39 < Laurenceb> englishman: I think I worked out your greenhouse heating system - how to do it for ~<$2/tube
2020-05-19T15:49:04 < Laurenceb> use a "direct, active drain-back" system
2020-05-19T15:49:58 < Laurenceb> only issue is the tanks will have to be buried
2020-05-19T15:50:32 < Laurenceb> then tanks -> solar powered pump -> panels -> header tank -> overflow back into storage tanks
2020-05-19T15:50:49 < Laurenceb> so when the pump is off the panels are empty, so no frozen water issues
2020-05-19T15:51:30 < Laurenceb> also you could add dual or triple redundant overheat cut off switches for the pump
2020-05-19T15:51:39 < Laurenceb> so no risk of overheating in summer
2020-05-19T15:58:05 < Laurenceb> solar panel area to power the pump will be something like 2% of the solar heater area

2020-05-19T16:01:43 < Laurenceb> https://www.viridiansolar.co.uk/assets/images/all-about-solar/Drainback-solar-thermal.jpg
2020-05-19T16:01:47 < Laurenceb> ingenious
2020-05-19T16:02:50 < Laurenceb> only the "header" tank could be buried and it can be lower than the panels, also you could use a motor controller with some supercaps for the water pump, to run it in bursts when its "stalled" with no water in the panels
2020-05-19T16:03:51 < Laurenceb> then you could use a puny pump and solar panel, as there is virtually no head to pump the water through
2020-05-19T16:05:43 < Cracki> do brits even know what sun is? do you know what "clouds" are? don't you guys have dark gray sky year round?
2020-05-19T16:06:24 < Laurenceb> lol this is why we have tube collectors
2020-05-19T16:06:33 < Laurenceb> they work even in cloudy weather
2020-05-19T16:07:50 < Cracki> what do they collect, the angry red rays of the eye of mordor?
2020-05-19T16:08:20 < englishman> Laurenceb: what is the risk of overheating in summer really? can't i just empty the tanks? or will the copper literally melt
2020-05-19T16:09:04 < Laurenceb> well according to the datasheets, peak temp is >300C inside the tubes
2020-05-19T16:09:18 < Laurenceb> if they are facing direct sun with no cooling at 25C ambient
2020-05-19T16:09:47 < Laurenceb> but they will survive that without issue as its pyrex tube
2020-05-19T16:10:23 < Laurenceb> most of the tube systems use heat pipes with refrigerant inside
2020-05-19T16:10:57 < Laurenceb> that goes to a heat exchanger at the top of the tube that heats the passing water
2020-05-19T16:11:47 < Laurenceb> so when the water is at >~70C, the refridgerant wont condense and the whole system "locks up" with gas phase refridgerant
2020-05-19T16:12:11 < Laurenceb> also it cant freeze in winter, as the top heat exchanger is insulated
2020-05-19T16:12:24 < Laurenceb> but that system more than doubles the cost
2020-05-19T16:13:38 < Laurenceb> I'm guessing these direct tube systems use o-rings at either end of the tube, presumably high temp o-rings mounted to a cooler part, maybe the outside of the tube even

2020-05-19T16:35:37 < englishman> i wonder if that heat can be used for anything useful in summer
2020-05-19T16:35:39 < Laurenceb> damp thats about $10/m^2, crazy low porices
2020-05-19T16:35:41 < englishman> how much is a steam turbine?
2020-05-19T16:35:44 < Laurenceb> lol
2020-05-19T16:36:05 < Cracki> pneumatically powered fridge
2020-05-19T16:36:36 < Laurenceb> efficiency would suck, but then again it would probably be >50% efficient at solar->heat 
2020-05-19T16:36:49 < Laurenceb> so it might be close to matching solar cells
2020-05-19T16:36:53 < englishman> it would be 100% efficient as the energy would be otherwise wasted
2020-05-19T16:36:59 < Laurenceb> yeah
2020-05-19T16:38:44 < englishman> why is the heat exchanger always at the top in those example setups?
2020-05-19T16:38:50 < englishman> why not at the bottom

2020-05-19T16:52:02 < karlp> pineapples are not a summer crop, that's 18months or so, depending on variety, and not all plants like growing in ground pineapples grew in if you're rotating.
2020-05-19T16:52:19 < karlp> pineapples ina  greenhouse sounds insane too, not a lot of fruit density 
2020-05-19T16:52:22 < Laurenceb> tbh
2020-05-19T16:52:32 < Laurenceb> who cares how it works at that price
2020-05-19T16:52:50 < Laurenceb> looks like <$10/m^2 of heated greenhouse
2020-05-19T16:53:21 < englishman> just for the tubes. and assuming your crazy price of $2/tube
2020-05-19T16:54:14 < Laurenceb> check the table
2020-05-19T16:54:25 < Laurenceb>  $138 for a whole system
2020-05-19T16:54:28 < englishman> which link
2020-05-19T16:54:33 < Laurenceb> the last one
2020-05-19T16:54:46 < Laurenceb> thats $2.3/tube, but includes a basic frame and manifold
2020-05-19T16:55:02 < englishman> lolwut.
2020-05-19T16:55:04 < Laurenceb> ikr
2020-05-19T16:55:24 < Laurenceb> makes sense if the tubes at $1.85 in bulk, which some of them sell for
2020-05-19T16:55:55 < Laurenceb> and assuming it passes the water directly through the tubes, it says "open both ends"
2020-05-19T16:56:30 < englishman> supplier: contacted
2020-05-19T16:56:41 < englishman> wut. so it's not vacuum?
2020-05-19T16:56:52 < englishman> more likely, both ends of the tubes are immersed
2020-05-19T16:57:23 < englishman> tho in the pics, it looks like there is a central manifold with tubes on both sides
2020-05-19T16:59:40 < karlp> how does the drainback prevent overheating in stagnation? is it only an overheating problem if there's fluid int eh pipes and it's idle?
2020-05-19T16:59:51 < karlp> so empty is ok, the tubes just get hot themselves?
2020-05-19T17:00:11 < englishman> that's the idea
2020-05-19T17:00:19 < englishman> there is no coolant in the manifold to boil over
2020-05-19T17:00:30 < englishman> and the tubes can survive the heat on their own
2020-05-19T17:00:36 < englishman> would need some high temp seals i suppose

2020-05-19T18:10:36 < englishman> also the coldest days are typically clear and sunny
2020-05-19T18:10:51 < englishman> it's the week of heavy overcast at -10C that would suck
2020-05-19T18:16:08 < englishman> apparently the tubes shatter in summer if water gets on it
2020-05-19T18:16:22 < Mangy_Dog> https://cdn.discordapp.com/attachments/362670523181957120/712322243488645180/IMG_20200519_161119.jpg oops, not as bad as it looks luckily... its just scorcing and wood/paint residue... the plastic is safe, but gonna have to clean it up D: i was using the wood as a guide tracing :/ ... lets not do that again
2020-05-19T18:20:31 < Laurenceb> https://gosun.co/blogs/news/why-tubes-break
2020-05-19T18:20:37 < Laurenceb> hmm that could be kind of bad
2020-05-19T18:20:58 < Laurenceb> but shouldnt happen if the drain back system only operates at night
2020-05-19T18:21:17 < Laurenceb> maybe some sort of safety interlock could be made
2020-05-19T18:21:49 < Laurenceb> like a thermal cutout that stops the pump running if internal tube temp is >150C
2020-05-19T18:22:15 < Laurenceb> that site says >200C thermal shock cracks the tubes
2020-05-19T18:22:36 < Laurenceb> ok cooking tiem, bbl
2020-05-19T18:25:24 < englishman> so they will have to be covered or cooled in summer
2020-05-19T18:25:27 < englishman> in case it rains
2020-05-19T18:31:12 < karlp> is that only if they're dry?
2020-05-19T18:31:28 < karlp> if you keep them circulating they're ok, but now you have constant energy fromt he pump and shit 
2020-05-19T18:33:46 < englishman> right so would need to be cooled, to prevent them overheating
2020-05-19T18:34:14 < englishman> or rather, to prevent the thermal shock due to rain
2020-05-19T18:34:54 < englishman> though i can see simply covering them up during the months they aren't needed
2020-05-19T18:35:13 < karlp> starting to really see the appeal of docker for build slaves after setting up this build server again
2020-05-19T18:39:45 < zyp> karlp, containers are perfect when you want a replicatable build environment
2020-05-19T18:40:07 < karlp> I had an old jenkins on a very old ubuntu and it was all setup loooonnnng ago
2020-05-19T18:40:08 < zyp> less useful for dev work, but for CI, containers all the way
2020-05-19T18:40:35 < karlp> still think I'm going to jsut hack it up right now, instead of porting it all to containers
2020-05-19T18:45:48 < zyp> was this posted already? https://blog.st.com/qsmp-stm32mp1/
2020-05-19T18:45:54 < zyp> octavo competitor, looks like

2020-05-20T00:32:49 < Cracki> ok so how many bits per second of colorful things to show

2020-05-20T00:36:14 < Cracki> so there's this FSMC thing. maybe you can address multiple displays on the same bus (different address ranges?), or maybe each gets an enable signal beside FSMC
2020-05-20T00:37:39 < zyp> yeah, if it's memory mapped displays, you could just throw them on FSMC with an address decoder

2020-05-20T00:37:51 < Thorn> I need clocks (bit, vsync, hsync) for each display
2020-05-20T00:38:06 < zyp> now you're making it harder :)
2020-05-20T00:38:29 < Cracki> parallel data bits eh
2020-05-20T00:38:47 < zyp> sounds like either fpga or multiple mcus to me
2020-05-20T00:38:51 < Cracki> they could share the same clocks, and each gets a 16 bit port to dma onto?
2020-05-20T00:39:23 < Thorn> and the interface needs to run at the proper speed required by the display
2020-05-20T00:39:32 < Cracki> are there chips that listen to FSMC and send bits+sync out?
2020-05-20T00:39:40 < Thorn> well the displays are identical so clocks can be shared
2020-05-20T00:39:46 < zyp> or you could run them as one display with reduced number of bits
2020-05-20T00:40:01 < zyp> e.g mcu outputs 24 bits, each display gets 6 bits :)
2020-05-20T00:40:09 < qyx> or 2 bits, such colours
2020-05-20T00:40:15 < zyp> but now you're gonna say you need more than 6-bit colors
2020-05-20T00:40:20 < Cracki> what data rate, bits per second for whole screen area?
2020-05-20T00:41:52 < zyp> if mcu output supports 4x the pixel rate, you could interleave pixels and demux them between mcu and displays
2020-05-20T00:42:13 < zyp> which would probably require a small fpga or something
2020-05-20T00:43:06 < Cracki> (I'd love to have an stm32 with a little bit of programmable logic, as a complement to those ZYNQ things)
2020-05-20T00:43:40 < Thorn> 6 bit colors are enough for me
2020-05-20T00:44:48 < zyp> cool, then you can just treat them as a 24-bit display
2020-05-20T00:46:44 < Thorn> ... or not (what about antialiased lines and stuff)
2020-05-20T00:48:46 < Laurenceb> englishman: ok I think I understand it now
2020-05-20T00:48:49 < Laurenceb> https://www.alibaba.com/product-detail/vacuum-solar-collector-China-for-pool_2022879741.html?spm=a2700.galleryofferlist.0.0.4cc4348ceJYgU2&fullFirstScreen=true
2020-05-20T00:49:00 < zyp> you could do some antialiasing with 6bpp
2020-05-20T00:49:06 < Laurenceb> these guys spill the beans, water is passed directly through the tubes
2020-05-20T00:49:11 < zyp> but eh
2020-05-20T00:49:17 < Cracki> 6 bit total means 2 bits per channel, or 64 entry palette, if the display supports that
2020-05-20T00:49:28 < englishman> Laurenceb: btw what is the heat loss in winter with that 30C differential? so I can compare cost to installing electric
2020-05-20T00:49:50 < zyp> Cracki, unlikely it supports palette when it doesn't got a framebuffer
2020-05-20T00:49:56 < Cracki> rgb 565 would mean 16 bits per panel, that's close enough to TrveColor
2020-05-20T00:49:57 < Laurenceb> it says in the spec sheet, about 0.6W/m^2/C for the solar panels
2020-05-20T00:50:22 < Thorn> I doubt if anything with an RGB interface can support a palette
2020-05-20T00:50:27 < Cracki> just speculating
2020-05-20T00:50:45 < zyp> Thorn, exactly
2020-05-20T00:50:57 < Cracki> if it can decode 565, that means it knows how to turn 5 and 6 bits into a full value range at least, and palette wouldn't be much more trouble
2020-05-20T00:50:58 < Thorn> if it had an internal framebuffer then that implies a sufficiently smart controller
2020-05-20T00:51:07 < Cracki> assuming it can decode 565
2020-05-20T00:51:11 < Laurenceb> englishman: oh for the greenhouse? I was getting about 1.5kwhr/day/m^2 input thermal energy
2020-05-20T00:51:44 < Steffanx> In methlab?
2020-05-20T00:52:02 < Cracki> palette means (small) fast memory. I agree, sounds unlikely
2020-05-20T00:52:17 < Laurenceb> yes of course
2020-05-20T00:52:19 < Cracki> anyway, aren't those displays a known quantity? I mean, datashiet or gtfo
2020-05-20T00:52:28 < englishman> kWh per day?
2020-05-20T00:52:41 < Laurenceb> lol payback time is 3 months at $15/m^2 and 0.15CAD/kwhr
2020-05-20T00:52:43 < Laurenceb> yeah
2020-05-20T00:52:45 < englishman> thats only 3.8 kW for 60 m^2? that isnt enough
2020-05-20T00:52:46 < Steffanx> Do you ever try all the theories in practice Laurenceb ?
2020-05-20T00:52:46 < Cracki> kW/24
2020-05-20T00:53:13 < Steffanx> Or will it be like your rockoon rocket? ;)
2020-05-20T00:53:14 < Laurenceb> englishman: for the input power, not accounting for the solar gain
2020-05-20T00:53:20 < Laurenceb> from the sun
2020-05-20T00:53:35 < englishman> sure the greenhouse is selfheated during the daytime
2020-05-20T00:53:52 < zyp> Thorn, where's the display content coming from?
2020-05-20T00:54:15 < zyp> how fast do you need to change it?
2020-05-20T00:54:19 < englishman> hmm i guess that's a lot, thats $8 per day of electricity
2020-05-20T00:54:33 < Thorn> rendered by firmware which receives data/commands over an interface. similar to HMI, roughly speaking
2020-05-20T00:54:41 < Laurenceb> ideally you need some weather data lol
2020-05-20T00:54:47 < Laurenceb> simulate it properly
2020-05-20T00:54:49 < Cracki> in terms of fps?
2020-05-20T00:54:52 < Thorn> a few times per second probably, like 5
2020-05-20T00:55:02 < Cracki> relaxing
2020-05-20T00:55:08 < englishman> Laurenceb: that could be a translation problem, they could be talking about the fluid in the heatpipe
2020-05-20T00:55:14 < englishman> Laurenceb: i have lots of weather data
2020-05-20T00:55:18 < Cracki> display timings give you what constraints on slowest possible data date?
2020-05-20T00:55:19 < Cracki> *rate
2020-05-20T00:55:32 < Laurenceb> englishman: I dont think so as the cost is so low
2020-05-20T00:55:42 < zyp> Thorn, you could e.g. throw an ice40up5k in front of each display, they've got 1MB of internal ram that you could use for a framebuffer, and then just feed that with FSMC or SPI or whatever
2020-05-20T00:56:10 < Laurenceb> it all makes sense if you assume the water goes through the pipes, otherwise they couldnt make a profit even at china wholesale prices for their parts
2020-05-20T00:56:51 < Laurenceb> just means the drainback system design is needed https://www.viridiansolar.co.uk/resources-3-6-solar-thermal-plumbing.html
2020-05-20T00:56:59 < zyp> but if you're not dead set on the specific displays you've picked, it might be cheaper to just switch to a display that already does that internally and gives you a parallel or spi interface
2020-05-20T00:58:47 < zyp> (disclaimer: I haven't checked if ice40up is actually fast enough, I hear they are relatively slow)
2020-05-20T01:01:57 < zyp> nah, that must be just latency wise, io buffers are rated up to 250 MHz
2020-05-20T01:02:02 < kakimir> I think I need to build a pelton turbine
2020-05-20T01:02:29 < kakimir> there is 330meters tall hill next to place where I live
2020-05-20T01:02:36 < zyp> 480x800x60fps is only like 23MHz pixel rate plus any blanking interval overhead
2020-05-20T01:03:41 < aandrew> kakimir: damn that's a tall hill
2020-05-20T01:03:56 < kakimir> but it's nowhere near being a mountain
2020-05-20T01:05:04 < zyp> how do you distinguish?
2020-05-20T01:05:18 < qyx> englishman: so far 4x panels with propylene glycol, heat exchanger, 3 cubic metres of water in accumulation tanks (I am using it for floor heating, planning post-recuperation heater and hot potable water using another exchanger)
2020-05-20T01:06:25 < aandrew> qyx: solar heating using those vacuum tubes is something I've been eyeing for a while
2020-05-20T01:06:39 < qyx> aandrew: not vacuum tubes, hewalex flat panels
2020-05-20T01:07:23 < qyx> Laurenceb: in practice you have nearly zero heat gain during the second half of November, December and the first half of January, at least in .sk
2020-05-20T01:08:03 < qyx> this year there were like ~20 continuous overcast days with exactly 0 heat gain
2020-05-20T01:08:11 < Laurenceb> damn
2020-05-20T01:08:24 < Laurenceb> this is using vacuum tubes?
2020-05-20T01:08:32 < Laurenceb> oh i see

2020-05-20T01:10:36 < qyx> 2100
2020-05-20T01:11:03 < qyx> tlp2100ac or what exactly
2020-05-20T01:14:16 < Laurenceb> heat loss coefficient is 3.25W/m^2/K
2020-05-20T01:14:26 < Laurenceb> so 5 times worse than tubes
2020-05-20T01:14:42 < Laurenceb> that cant be helping
2020-05-20T01:16:38 < Laurenceb> I saw a demo of tube versus flat plate at a museum, under uk cloudy sky, flat plate was barely warm but vacuum tube was at 65C

2020-05-20T01:22:05 < Laurenceb> but yeah, probably needs simulation with actual weather data
2020-05-20T01:27:04 < englishman> Laurenceb: but the insulating effects of the vacuum are lost. there's no way that's effective in -20C
2020-05-20T01:27:26 < englishman> qyx: I thought you lived in an apartment?
2020-05-20T01:27:48 < Laurenceb> 30*0.6=18W/m^2 at 30C delta t
2020-05-20T01:27:54 < Laurenceb> so tiny energy loss
2020-05-20T01:28:13 < englishman> ?
2020-05-20T01:28:17 < Laurenceb> even at 40C tank temp its only 36W/m^2
2020-05-20T01:28:18 < englishman> what is that calculation
2020-05-20T01:28:34 < qyx> englishman: yeah but building new semi-passive offgrid
2020-05-20T01:28:37 < Laurenceb> the spec for vacuum collectors is 0.6W/m^2/C
2020-05-20T01:28:54 < Laurenceb> >5 times lower than flat plate
2020-05-20T01:29:11 < englishman> yeah, that vacuum really makes a difference
2020-05-20T01:29:17 < englishman> also > times less
2020-05-20T01:29:22 < englishman> don't do that
2020-05-20T01:29:43 < Laurenceb> but the insulating effects of the vacuum are lost
2020-05-20T01:29:49 < Laurenceb> ^ what are you trying to say?
2020-05-20T01:30:11 < kakimir> you know they made a material that radiates heat away
2020-05-20T01:30:11 < Laurenceb> inb4 emdrive kills the vacuum with help from Qanon
2020-05-20T01:30:17 < englishman> if you just pump water through black pipes, the water isn't insulated from the outside
2020-05-20T01:30:28 < englishman> with the vacuum system, the water is always insulated
2020-05-20T01:30:35 < Laurenceb> yeah
2020-05-20T01:30:37 < kakimir> it actually frozes from radiating it's heat
2020-05-20T01:30:45 < englishman> and the copper is insulated from the cold too, from the vacuum
2020-05-20T01:31:01 < Laurenceb> kakimir: thats why that drain back design is used
2020-05-20T01:31:25 < englishman> might as well just put black PVC pipe in the sun at that rate
2020-05-20T01:31:39 < englishman> instead of buying glass tubes
2020-05-20T01:31:44 < kakimir> https://physicstoday.scitation.org/do/10.1063/PT.5.028465/full/
2020-05-20T01:32:04  * Laurenceb confused
2020-05-20T01:32:23 < Laurenceb> black pvc will be useless apart from in summer
2020-05-20T01:32:45 < englishman> if there's actually water cycling through those chinese pipes, what is the difference?
2020-05-20T01:32:56 < qyx> wat
2020-05-20T01:33:06 < Laurenceb> they have 55mm insulation over all piping
2020-05-20T01:33:07 < englishman> and yes, that's the point, and why qyx doesn't gain any heat in winter
2020-05-20T01:33:11 < Laurenceb> and pipes drain over night
2020-05-20T01:33:37 < Laurenceb> no its because he has flat plate
2020-05-20T01:33:51 < qyx> I don't have such insulation
2020-05-20T01:34:05 < englishman> what's the difference between flat plate and a bunch of tubes next to each other
2020-05-20T01:34:05 < qyx> there is few cm of rockwool from the back
2020-05-20T01:34:17 < Thorn> soviet labview lol https://www.youtube.com/watch?v=EhEewUXHwNY
2020-05-20T01:34:25 < qyx> and about ~2cm of air gap + glass from the front
2020-05-20T01:35:16 < Laurenceb> yeah that makes a huge difference
2020-05-20T01:36:18 < englishman> so it's air insulated
2020-05-20T01:36:57 < englishman> Laurenceb: i think that page is a translation issue they look like normal vac tubes
2020-05-20T01:37:20 < englishman> and the manifold is correct for a normal vac tube
2020-05-20T01:39:21 < Laurenceb> nah I think they normally mount sideways
2020-05-20T01:39:38 < Laurenceb> but yeah they use normal tubes, open at only one end
2020-05-20T01:39:50 < englishman> ive only seen vertical, and sideways if the manifold has tubes on both sides
2020-05-20T01:39:52 < Laurenceb> then convection currents circulate the water within each tube
2020-05-20T01:39:59 < Laurenceb> yeah
2020-05-20T01:40:09 < englishman> ?? the ones ive seen dont have any water at all in them
2020-05-20T01:40:12 < Laurenceb> but refridgerant systems wont work mounted sideways
2020-05-20T01:40:16 < englishman> just a copper heatpipe, and vacuum
2020-05-20T01:40:37 < Laurenceb> I think they fill up with water in use
2020-05-20T01:40:48 < Laurenceb> the cheap ones, not the heat pipe ones of course
2020-05-20T01:41:17 < englishman> with the vacuum at $5 why bother with cheap
2020-05-20T01:41:53 < englishman> https://youtu.be/XAVaOQ1o67w?t=72
2020-05-20T01:42:01 < Laurenceb> because $1.7
2020-05-20T01:42:43 < qyx> how many do you need to get 1m^1?
2020-05-20T01:42:48 < qyx> 1m^2

2020-05-20T01:56:00 < englishman> so chinese call it "non-pressurized"
2020-05-20T01:56:09 < englishman> and the vaccum ones are "pressurized"
2020-05-20T01:56:19 < englishman> thats true i think their word for vacuum is the same as pressure
2020-05-20T01:56:19 < Laurenceb> ikr
2020-05-20T01:56:39 < Laurenceb> nah pressurised refers to refridgerant fill

2020-05-20T03:09:33 < Laurenceb> they have fully stainless pumps for solar applications with no corrosion supressing additives
2020-05-20T03:15:59 < englishman> also it freezes
2020-05-20T03:18:00 < Laurenceb> thats why you use the draining design
2020-05-20T03:19:23 < englishman> another benefit of the vacuum tubes: when one tube breaks, it doesnt pump all your fluid out

2020-05-20T11:01:30 < PaulFertser> What's the rationale compared to squashfs?
2020-05-20T11:14:29 < zyp> qyx, pcie sockets are 14.5mm from the notch to the end, looks like the sides of the groove in the rail are the tallest part and if the groove is like 2mm deep then putting the notch 17mm away from the card edge should be safe
2020-05-20T11:14:54 < zyp> and that's exactly where I happen to have it now

2020-05-20T11:36:20 < qyx> PaulFertser: because someone in at91/openwrt decided it is a good idea to use it for this devel board

2020-05-20T13:28:25 < zyp> the latter got some coding stuff for compactpci/vme and takes up 4TE, the former looks like it'll fit in 2TE

2020-05-20T14:01:49 < Mangy_Dog> not 10cm

2020-05-20T14:04:42 < Mangy_Dog> just the front page said <5cmx5cm
2020-05-20T14:04:47 < zyp> fuck, the board I'm designing now will need 6L though :)
2020-05-20T14:04:52 < Mangy_Dog> ouch
2020-05-20T14:08:59 < zyp> anyway, 4L becoming even more affordable than 2L used to be is great
2020-05-20T14:09:09 < Mangy_Dog> nods
2020-05-20T14:09:12 < zyp> limited time offer for now, but it's trending in the right direction
2020-05-20T14:09:21 < Mangy_Dog> its certainly something to considder in future project now
2020-05-20T14:09:27 < Mangy_Dog> ive managed to get away with 2 layer boards for ages
2020-05-20T14:09:30 < Mangy_Dog> even this tricorder
2020-05-20T14:10:12 < zyp> I've done a bunch of 4L boards already
2020-05-20T14:10:31 < zyp> hard to go back to 2L afterwards
2020-05-20T14:10:36 < Mangy_Dog> nods
2020-05-20T14:10:54 < Mangy_Dog> the abilioty to pretty much dedicate 2 layers to pure ground and power is so much freedom
2020-05-20T14:11:02 < Mangy_Dog> plus built in shielding for high speed stuff
2020-05-20T14:11:13 < Mangy_Dog> much less headachey
2020-05-20T14:11:56 < zyp> shielding doesn't matter that much to me, but impedance does

2020-05-20T14:12:21 < Mangy_Dog> board impeadance is something i still dont really know much about
2020-05-20T14:13:40 < zyp> Thorn, well, they claim 3.5/3.5 at no extra cost
2020-05-20T14:14:06 < zyp> Mangy_Dog, not board impedance, trace impedance

2020-05-20T14:19:29 < zyp> Mangy_Dog, the short story is that conductors close to each other forms a capacitor, a conductor loop forms an inductor, and when you have traces on a pcb you get both of those effects with the values affected by the geometry
2020-05-20T14:20:49 < zyp> inductors and capacitors are both impedances, and to keep your signal from degrading, you want your transmission line to have the same characteristic impedance as the transmitter and receiver impedance

2020-05-20T14:22:41 < Mangy_Dog> ahh
2020-05-20T14:22:49 < zyp> for a microstrip (signal trace running over a ground plane) with a given impedance, there's a proportional relationship between the width of the trace and the distance between the trace and the ground plane
2020-05-20T14:23:12 < Mangy_Dog> then my tricorder pcb might be all over the place :D
2020-05-20T14:23:19 < Mangy_Dog> luckily im not doing any high speed stuff
2020-05-20T14:24:17 < zyp> and the difference between 2L boards and 4L boards is that on a 2L board, you have like 1.5mm between the trace and the ground plane on the opposite side, while on a 4L board, you've got like 0.1-0.2mm between an outer trace and an inner ground plane
2020-05-20T14:24:59 < Thorn> and there's quite a bit of difference between 0.1 and 0.2mm impedance wise lol
2020-05-20T14:25:33 < zyp> sure, but there's a bigger difference between 0.2mm and 1.5mm :)
2020-05-20T14:26:20 < Thorn> apparently there's a popular prepreg 0.64mm thick and many pcb houses use 2 layers of it
2020-05-20T14:26:31 < zyp> in other words, to get proper impedance on a 2L board, transmission line traces have to be on the order of 10x as wide as they have to on a 4L board
2020-05-20T14:26:57 < Thorn> *0.064mm
2020-05-20T14:27:13 < Thorn> which gives around 0.125mm between layer pairs
2020-05-20T14:27:42 < zyp> which results in crazy layouts like e.g. this: https://i.stack.imgur.com/6cgrt.png (random google image search result)
2020-05-20T14:28:30 < Thorn> lol
2020-05-20T14:28:50 < Mangy_Dog> :D thats some hefty trace length matching going on there
2020-05-20T14:28:55 < Cracki> oh right I wanted to check their 4l stackup
2020-05-20T14:29:08 < zyp> jlcpcb? they offer both 0.1 and 0.2
2020-05-20T14:29:12 < Thorn> what about those tiny vias in those fat traces
2020-05-20T14:29:16 < Mangy_Dog> or is that impeadence matching rather than trace matching?
2020-05-20T14:29:21 < Thorn> that's a discontinuity isn't it
2020-05-20T14:29:44 < zyp> dunno, I figure vias are discontinuities no matter what
2020-05-20T14:29:48 < Thorn> that kind of length matching is not needed with 100 MBit RMII
2020-05-20T14:29:53 < Cracki> ah good, it's 1|2_3|4, not something funky like 1_2|3_4
2020-05-20T14:30:21 < zyp> that looks like too many traces for RMII, guessing it might be MII
2020-05-20T14:30:22 < Mangy_Dog> well those vias internal surface might be fairly close match to the external flat trace
2020-05-20T14:30:25 < zyp> which is even slower
2020-05-20T14:30:26 < Mangy_Dog> surface size
2020-05-20T14:30:45 < Mangy_Dog> but yeah even i think they look small
2020-05-20T14:30:58 < zyp> Mangy_Dog, yes
2020-05-20T14:31:10 < zyp> vias have a lot more surface area than people realize
2020-05-20T14:31:15 < Mangy_Dog> nods
2020-05-20T14:31:36 < Mangy_Dog> surface area was the word i was grabbing for but brain said no
2020-05-20T14:32:37 < zyp> and four small vias in a 2x2 pattern has twice as much surface area as a larger via twice the diameter, despite having the same hole area
2020-05-20T14:33:29 < zyp> so for power stuff, to increase current capacity it's more reasonable to increase the number of minimum size vias than to increase the size
2020-05-20T14:33:45 < zyp> also for thermal conduction
2020-05-20T14:34:26 < sync> yeah this looks like a lot of autism for just 100mbit ethernet
2020-05-20T14:36:11 < Mangy_Dog> https://cdn.discordapp.com/attachments/337706779708489728/712629268554973214/IMG_20200520_123332.jpg second half of my stargate parts mould poored, one of teh air vents fell off :( so gonna have to drill the silicone to amek a new one... not great
2020-05-20T14:36:39 < zyp> Thorn, which 0.8mm bga are you planning to do?
2020-05-20T14:36:56 < Cracki> so... you talking about via surface area implies their cross sectional area is irrelevant?
2020-05-20T14:37:05 < Thorn> either mp1 or zynq + ddr3
2020-05-20T14:37:27 < zyp> Thorn, how many rings of signals do you need to fan out?
2020-05-20T14:37:45 < Thorn> probably 4
2020-05-20T14:38:34 < zyp> should be fairly doable
2020-05-20T14:39:41 < zyp> ecp5 has five rings of IO
2020-05-20T14:40:26 < zyp> https://bin.jvnv.net/file/rCCA8.png
2020-05-20T14:41:45 < zyp> and I'll be using pretty much all of banks 2, 3, 6 and 7 to hook up the ddr3 sodimm, so I'm currently wondering how the fuck I'm going to manage fanning out the inner pads in those banks
2020-05-20T14:43:31 < zyp> I'm planning on 6L, but I want to keep all the highspeed stuff on the outer layers so I ony 0
2020-05-20T14:43:52 < Cracki> how would one use the jlc 6-layer stackup? | 0.1 | 0.565 | 0.127 | 0.565 | 0.1 | would make me think 3x (power/gnd+signal). what about using the two inner ones for signals? they're close together, I guess that could limit performance on those?
2020-05-20T14:44:05 < zyp> so I only have one set of impedance numbers to care about
2020-05-20T14:45:01 < zyp> yeah
2020-05-20T14:45:11 < Thorn> Cracki 1+6=high speed signals, 2+5 = gnd, 3+4 = power and low speed signals I guess
2020-05-20T14:45:20 < Mangy_Dog> D: that 20x20 bga
2020-05-20T14:45:23 < Cracki> ic
2020-05-20T14:45:26 < zyp> yes, that's exactly what I had in mind
2020-05-20T14:45:27 < Mangy_Dog> what sadist invented that !
2020-05-20T14:45:47 < zyp> Mangy_Dog, what about it?
2020-05-20T14:45:57 < Mangy_Dog> just not a fan of bgas
2020-05-20T14:45:58 < Mangy_Dog> :p
2020-05-20T14:46:04 < Cracki> 2+5 one ground one power, how much would that hurt? :D
2020-05-20T14:46:18 < Mangy_Dog> i mean i really hope i never have to solder one (i know i will one day, but ilol get therepy afterwards)
2020-05-20T14:47:09 < Cracki> if a chinese sweatshop can do it over a wood fire, you can do it
2020-05-20T14:47:19 < Mangy_Dog> lol
2020-05-20T14:47:35 < Mangy_Dog> and im debating spending 30 quid on a toaster oven to do reflow in
2020-05-20T14:47:37 < Cracki> gutter "oil" for flux
2020-05-20T14:47:45 < Cracki> sounds like a good investment
2020-05-20T14:47:53 < zyp> Mangy_Dog, the bga381 is the smallest reasonable option for my design, there's also a bga554 and a bga756
2020-05-20T14:47:55 < Cracki> *expense
2020-05-20T14:48:11 < Mangy_Dog> well its not terrible
2020-05-20T14:48:17 < Mangy_Dog> but im spending way to much money right now :/
2020-05-20T14:48:23 < Mangy_Dog> this stargate project is costing me far too much
2020-05-20T14:48:35 < Mangy_Dog> im eating away my emergency savings a lot right now
2020-05-20T14:48:40 < Mangy_Dog> :/
2020-05-20T14:48:55 < Mangy_Dog> im unemployed on benifits sooooo no real income
2020-05-20T14:49:07 < Thorn> the zynq I'm looking at has 400 balls. there's a 225 ball version but it's probably not enough
2020-05-20T14:49:30 < Cracki> hot plate reflow then
2020-05-20T14:49:47 < zyp> Mangy_Dog, by the way, bga is easy to solder
2020-05-20T14:49:50 < Mangy_Dog> been considering that too
2020-05-20T14:49:53 < Cracki> best use leaded solder, melts at frying pan temperatures :>
2020-05-20T14:50:01 < Mangy_Dog> heh
2020-05-20T14:50:08 < zyp> I've done it a couple of times before, just put the part on the board and throw it in the oven
2020-05-20T14:50:14 < Mangy_Dog> the other issue of getting a oven to do reflow in......
2020-05-20T14:50:19 < Mangy_Dog> id have to develop a controller :/
2020-05-20T14:50:24 < Mangy_Dog> and i kinda dont want to put in the time for that
2020-05-20T14:50:24 < zyp> IME 1mm bga is way easier than 0.5mm qfn
2020-05-20T14:50:34 < Cracki> nah, you just need a temp probe and your hands on the knob
2020-05-20T14:50:36 < zyp> I don't expect 0.8mm to be significantly harder
2020-05-20T14:50:50 < Mangy_Dog> i find qfn fine
2020-05-20T14:51:00 < Mangy_Dog> flood with flux and solder and wick away
2020-05-20T14:51:13 < Mangy_Dog> louis rossmen way
2020-05-20T14:51:15 < Mangy_Dog> :D
2020-05-20T14:51:16 < zyp> qfn is very footprint sensitive
2020-05-20T14:52:31 < Thorn> with bga there's not much room for different techniques or fixing afterwards. just put it down and heat it up (and pray)
2020-05-20T14:53:29 < Mangy_Dog> also at least with qfn you can see if the pads are lined up correctly
2020-05-20T14:53:37 < Mangy_Dog> bga is kinda a shot in the dark
2020-05-20T14:53:39 < zyp> Thorn, yes, but less room for fucking up in the first place
2020-05-20T14:53:45 < zyp> Mangy_Dog, meh
2020-05-20T14:53:58 < Mangy_Dog> unless you have a good accurate pick and place machine doing it :p

2020-05-20T14:55:08 < Cracki> you can probably rig something up with a webcam. you'd want one shot of the blank board, and alpha blend that on top of the live picture, so you see the pcb pads and the chip at the same time
2020-05-20T14:55:10 < Mangy_Dog> looking at this one
2020-05-20T14:55:19 < Mangy_Dog> gonna see if i can get awway with making an offer or 15 quid
2020-05-20T14:55:20 < Mangy_Dog> :D
2020-05-20T14:55:32 < Mangy_Dog> horrible looking oven though
2020-05-20T14:55:36 < Cracki> how much for shipping
2020-05-20T14:55:41 < zyp> https://bin.jvnv.net/file/1r2uh.JPG <- you can just look from the side, bga sits fairly high over the board compared to a qfn
2020-05-20T14:55:47 < Cracki> you can probably get a cheap one at local yard sales?

2020-05-20T14:56:07 < Mangy_Dog> i prefer the looks of this one
2020-05-20T14:56:11 < Mangy_Dog> but its underpowered
2020-05-20T14:56:44 < zyp> also, it's pretty hard to fuck up bga alignment
2020-05-20T14:57:14 < Mangy_Dog> even on a 0.5 pich bga?
2020-05-20T14:57:16 < Mangy_Dog> pitch
2020-05-20T14:57:24 < zyp> just place it so you can still see silk outline on all four sides, the rest will be taken care of by surface tension
2020-05-20T14:57:39 < Mangy_Dog> thats another thing ive been struggling with lately
2020-05-20T14:57:41 < Cracki> solder surface tension
2020-05-20T14:57:51 < Mangy_Dog> ive been using this bismith lead free paste
2020-05-20T14:58:02 < Cracki> if it's rotated, you see it. if it's off by n, you see it from silk screen
2020-05-20T14:58:07 < Mangy_Dog> it balls up like a bugger and really doesnt do surface tension
2020-05-20T14:58:33 < Cracki> bismuth? sounds special purpose
2020-05-20T14:58:43 < Mangy_Dog> its meant to be a lower temp lead free
2020-05-20T14:58:51 < Mangy_Dog> and the spelling might be wrong :D
2020-05-20T14:58:59 < Mangy_Dog> closer to leaded solder
2020-05-20T14:59:02 < Mangy_Dog> temp wise
2020-05-20T14:59:28 < Mangy_Dog> but i end up with tons and tons of little ball bearings over my pcb they dont flow into the pads that well
2020-05-20T14:59:39 < Mangy_Dog> and they dont really create tension for the parts to align
2020-05-20T14:59:44 < zyp> sounds like desoldering paste
2020-05-20T14:59:48 < Cracki> ^
2020-05-20T14:59:52 < zyp> like that chipquik thing or whatever it was called
2020-05-20T15:00:00 < Cracki> that's probably what it is
2020-05-20T15:00:13 < Cracki> you're using desoldering stuff for soldering :D
2020-05-20T15:00:26 < Cracki> only time I heard of bismuth stuff was for desoldering
2020-05-20T15:00:33 < Mangy_Dog> hmm?
2020-05-20T15:01:01 < Cracki> maybe whatever flux it has is weird

2020-05-20T15:29:58 < englishman> Laurenceb: definitely not touching those water-filled tubes, there are so many downsides
2020-05-20T15:30:10 < englishman> can you imagine taking apart and cleaning 600 tubes every 2 years
2020-05-20T15:30:11 < englishman> fuck that
2020-05-20T15:30:16 < Laurenceb> wut
2020-05-20T15:30:19 < englishman> and if one cracks, all your fluid is gone
2020-05-20T15:30:22 < Laurenceb> why would you need to clean it
2020-05-20T15:30:26 < englishman> because of buildup?
2020-05-20T15:30:30 < Laurenceb> its a closed system
2020-05-20T15:30:33 < englishman> closed with water
2020-05-20T15:30:38 < Laurenceb> buildup only happens in open systems
2020-05-20T15:30:46 < englishman> only if you use distilled water
2020-05-20T15:30:50 < Laurenceb> where fresh water is always going through
2020-05-20T15:30:53 < Laurenceb> nah
2020-05-20T15:31:03 < Laurenceb> there will be tiny buildup in a closed system
2020-05-20T15:31:04 < englishman> there are so many downsides dude
2020-05-20T15:31:09 < englishman> and the cost is the same
2020-05-20T15:31:23 < Laurenceb> not if you buy from china
2020-05-20T15:31:32 < Laurenceb> its less than half the price of heat pipe stuff
2020-05-20T15:31:50 < Laurenceb> >all your fluid is gone
2020-05-20T15:31:54 < englishman> as a system cost the difference is less than 2k right
2020-05-20T15:31:56 < Laurenceb> its just water
2020-05-20T15:31:59 < Laurenceb> yeah
2020-05-20T15:32:13 < englishman> yeah not putting pure water in an outdoor system at -20C ambient
2020-05-20T15:32:14 < englishman> not happening
2020-05-20T15:32:22 < englishman> that might seem OK in a whiteroom academic setting
2020-05-20T15:32:27 < englishman> in the real world, water freezes
2020-05-20T15:32:37 < Laurenceb> nah its how its done in many commercial systems
2020-05-20T15:32:38 < englishman> especially when you don't want it to
2020-05-20T15:32:46 < Laurenceb> with redundant safety systems its safe
2020-05-20T15:32:53 < Laurenceb> you get to make a cool controller unit

2020-05-20T15:35:37 < zyp> and the bulb is where?

2020-05-20T15:35:57 < englishman> yes
2020-05-20T15:36:14 < zyp> then how is there a difference to frost risk?
2020-05-20T15:36:24 < englishman> it is still a risk
2020-05-20T15:36:25 < Laurenceb> its not alcohol its R143z
2020-05-20T15:36:33 < Laurenceb> *s/z/a
2020-05-20T15:36:44 < englishman> the advantages of the heatpipes are: if they break your coolant doesnt leak, and they dont need to be cleaned (just the bulb part in the manifold)
2020-05-20T15:36:59 < Steffanx> True, mawk
2020-05-20T15:37:04 < Laurenceb> arggg ur like someone who would be scammed by a used car dealer englishman

2020-05-20T15:38:16 < englishman> looks like the heatpipe ones are more efficient as well
2020-05-20T15:38:21 < zyp> but yeah, the drainback figure that Laurenceb linked to looks frost safe to me
2020-05-20T15:38:28 < zyp> are they?
2020-05-20T15:38:40 < Laurenceb> they are used widely in uk
2020-05-20T15:38:54 < englishman> at least according to the mfg website
2020-05-20T15:39:05 < zyp> I don't know, but intuitively I'd expect heatpipes to be less efficient, since they add another layer between the sun and the water
2020-05-20T15:40:10 < englishman> maybe because there is less coolant exposed to ambient?
2020-05-20T15:40:43 < zyp> could be
2020-05-20T15:40:52 < englishman> the volume of fluid in the heatpipe is much less than the volume of the tube, and there is an additional insulating layer of air around it
2020-05-20T15:44:19 < Laurenceb> system cost for this is something like $25/m^2 total https://imagebin.ca/v/5NAXpLu3XI3j
2020-05-20T15:44:49 < zyp> beats PV pretty well
2020-05-20T15:45:16 < zyp> both cost/area and power/area
2020-05-20T15:45:41 < Laurenceb> not when you add in carnot 
2020-05-20T15:45:42 < englishman> yes it may not be as elegant but they are quite efficient and cheap
2020-05-20T15:46:15 < Laurenceb> they are next to useless if you want electricity
2020-05-20T15:46:16 < zyp> Laurenceb, how so?
2020-05-20T15:46:23 < zyp> yes
2020-05-20T15:46:33 < Laurenceb> because the temperature is like 200C, so efficiency with steam turbine sucks
2020-05-20T15:46:35 < englishman> the vast majority of my electric bill is heat
2020-05-20T15:46:38 < englishman> so to me it's the same
2020-05-20T15:46:49 < dongs> time to buy some AMD boxes englishman 
2020-05-20T15:46:54 < dongs> I heard they're good space heaters
2020-05-20T15:46:54 < zyp> people don't use solar catchers for electricity
2020-05-20T15:47:02 < englishman> can they mine buttcoins
2020-05-20T15:47:39 < zyp> I mean, I will be getting PV, not solar catchers
2020-05-20T15:47:46 < Laurenceb> should pay for itself in about 1 year i think
2020-05-20T15:49:07 < zyp> I don't have water-borne heating, so I've got nowhere to put kilowatts of heat like that
2020-05-20T15:49:35 < englishman> same, for the house we'd have to refit, maybe in the next house
2020-05-20T15:49:45 < englishman> but by then, solar might be cheaper
2020-05-20T15:49:49 < englishman> PV solar
2020-05-20T15:50:08 < zyp> I don't think PV will ever beat vacuum tubes
2020-05-20T15:50:18 < zyp> in watts per cost

2020-05-20T15:50:42 < englishman> tubes are only about 1/3 of the cost though
2020-05-20T15:51:24 < zyp> how does that math work out?
2020-05-20T15:51:43 < englishman> tanks, radiators, plumbing, controls, labour
2020-05-20T15:51:48 < englishman> and glycol
2020-05-20T15:52:11 < zyp> I mean, assuming you already have water-borne heating, the additional plumbing shouldn't amount to that much
2020-05-20T15:52:20 < englishman> yes, but for me it's a new install
2020-05-20T15:52:59 < englishman> i could see tubes being around 1/2 the cost or a little more
2020-05-20T15:53:14 < englishman> the tanks, insulated plumbing, glycol still add up
2020-05-20T15:53:27 < zyp> I havent't looked at tube prices, but I've done the math on PV
2020-05-20T15:54:51 < zyp> IIRC my conclusion was that I could earn back the cost of a PV system in 4-5 years
2020-05-20T15:55:18 < englishman> pretty good
2020-05-20T15:55:19 < zyp> assuming I install it myself
2020-05-20T15:55:27 < zyp> and count that as free
2020-05-20T15:55:37 < englishman> with grid-tie?
2020-05-20T15:55:41 < zyp> yes
2020-05-20T15:55:44 < englishman> so no storage
2020-05-20T15:55:54 < englishman> that saves a lot of cost
2020-05-20T15:56:26 < zyp> storage doesn't make economical sense if grid-tie is an option

2020-05-20T15:59:17 < Laurenceb> GNU tool kit
2020-05-20T15:59:35 < zyp> I mean, consider it, you either need enough storage to store summer energy for winter, or a large enough system that you can get enough energy to cover average demand on an average winter day
2020-05-20T15:59:53 < mawk> how wouldn't that not leak out in the interval
2020-05-20T15:59:53 < Laurenceb> yeah seasonal thermal storage isnt happening easily
2020-05-20T15:59:57 < englishman> which is big $
2020-05-20T15:59:59 < zyp> the former is completely unfeasible and the latter is unlikely too
2020-05-20T16:00:03 < Laurenceb> unless you have a drilling rig...
2020-05-20T16:00:14 < Laurenceb> thats another option...
2020-05-20T16:00:40 < englishman> here it's 100% hydroelectric, so by using grid-tie i am effectively storing my energy in a reservoir
2020-05-20T16:00:41 < zyp> so grid-tie is the best bet, takes the storage need out of the equation since you can treat the grid as a battery
2020-05-20T16:00:59 < zyp> same
2020-05-20T16:01:09 < Steffanx> Im proud of you mawk. When will you rotare your flag 90 degrees?

2020-05-20T16:01:21 < mawk> :(
2020-05-20T16:02:56 < zyp> and then there's grid-tie storage like the tesla powerwall, but that doesn't make sense here now either, the prices doesn't vary enough to outweigh the cost of the battery

2020-05-20T16:24:34 < zyp> the house is new and well insulated, so I don't think it needs all that much heating, currently I've only got electric underfloor heating in the bathrooms and hallway and a small (like 1kW) post-heater after the heat exchanger in the ventilation system, and that was enough to get through last winter
2020-05-20T16:25:35 < zyp> plus heat from a couple of computers that are always on, and other stuff, of course
2020-05-20T16:26:59 < sync> ah you have a ventilation system
2020-05-20T16:33:31 < zyp> yeah, a balanced ventilation system with heat exchanger is almost mandated by the building rules since 2010
2020-05-20T16:34:10 < sync> ah, I usually help people rip them out again after the building is finished
2020-05-20T16:34:46 < zyp> it's not directly mandated, but there's requirements for fresh air and requirements for energy efficiency that'd be hard to meet without one
2020-05-20T16:35:06 < zyp> so in practice every house built since 2010 will have a ventilation system
2020-05-20T16:35:35 < zyp> and that's a good thing, IMO

2020-05-20T17:14:59 < zyp> but at this point I want it more for cooling down the house in the summer
2020-05-20T17:15:13 < zyp> Cracki, haha, so true

2020-05-20T18:30:02 < spacebyte> Hi all. Is ~6 seconds "normal" for chibios+lwip to detect that I have an ethernet cable connected and set the interface up? I need it to be a bit faster, but can't seem to understand if there's timeout I can configure
2020-05-20T18:32:06 < Cracki> start by getting information
2020-05-20T18:32:46 < Cracki> capture packets. log when chibios+lwip does something.
2020-05-20T18:33:09 < Cracki> you need to figure out what causes this and what doesn't
2020-05-20T18:34:11 < spacebyte> good point. I'll try with wireshark then
2020-05-20T18:35:13 < Cracki> you'll need to intercept the packets, or set a switch to mirror packets if you have that
2020-05-20T18:35:33 < Cracki> intercept i.e. put yourself in the middle, or be _on_ the host that does dhcp
2020-05-20T18:35:35 < zyp> not sure wireshark will be lowlevel enough
2020-05-20T18:35:45 < zyp> if the problem is autonegotiation and stuff
2020-05-20T18:36:01 < spacebyte> just another aspect: I'm setting a static Ip, and after the first link up, if I disconnect and connect the cable it detects pretty fast
2020-05-20T18:36:12 < spacebyte> I'm also setting "auto-negotiation" on
2020-05-20T18:36:49 < zyp> spacebyte, what happens with the lights on the port? how long does it take from plugging in the cable until they light up?
2020-05-20T18:36:53 < Thorn> spacebyte cable connection is first reported by the PHY over MDIO, plus it asserts an interrupt signal (if configured and connected)
2020-05-20T18:37:17 < Thorn> (well it's reported over MDIO when the MCU polls it)
2020-05-20T18:37:20 < zyp> yeah, might be slow PHY polling
2020-05-20T18:37:44 < Thorn> if your firmware isn't using the interrupt and polls the phy every 5 seconds then it's quite possible
2020-05-20T18:37:51 < Cracki> find a way to record those timings, look for a pattern
2020-05-20T18:38:13 < Cracki> get lwip to give you debug output, or wiggle I/O on certain events
2020-05-20T18:38:17 < Cracki> same with chibios
2020-05-20T18:38:27 < Cracki> find out where that time goes
2020-05-20T18:38:48 < spacebyte> zyp: the lights (both activity and speed/mode) come up way before lwip reports link up
2020-05-20T18:38:53 < Cracki> it could be sunk into all kinds of things. we can speculate but that doesn't help narrow it down.
2020-05-20T18:40:03 < spacebyte> Thorn: I'm using lwip, and set a callback for interface changes.
2020-05-20T18:41:48 < zyp> I bet it's slow phy polling :)
2020-05-20T18:43:07 < spacebyte> zyp: I think so yes. I've found LWIP_LINK_POLL_INTERVAL set at 5 seconds
2020-05-20T18:43:16 < Thorn> ror
2020-05-20T18:44:11 < spacebyte> It still takes a while but got down to 3/4 seconds
2020-05-20T18:44:48 < zyp> well, there's probably a bunch of small things that takes time
2020-05-20T18:45:44 < spacebyte> yes I'll keep looking. Sorry, the configuration was right in front of me and missed it. Thanks anyway. I'll report if I find anything else
2020-05-20T18:45:51 < zyp> autonegotiation needs to complete, then lwip needs to detect that, and then even with a static ip, you might have an arp cache to flush or whatever
2020-05-20T18:46:19 < Thorn> spacebyte does your setup time include dhcp negotiation?
2020-05-20T18:46:44 < spacebyte> Thorn: hope not because I'm using static IP, and configured lwip as such

2020-05-20T22:11:58 < zyp> https://bin.jvnv.net/file/jBtuh.png <- I feel like I'm halfway figuring this out and halfway painting myself into a corner by blocking the way for pads that aren't assigned to any nets yet but that I'll probably need later
2020-05-20T22:14:18 < Cracki> does this program have auto breakout?
2020-05-20T22:14:43 < Cracki> looks like it does, you broke out bundles at a time
2020-05-20T22:14:50 < zyp> altium? I presume it does, but I want this fanned out in a reasonable order as well
2020-05-20T22:14:54 < zyp> no, I did this by hand
2020-05-20T22:14:59 < Cracki> oh, very neat
2020-05-20T22:15:07 < zyp> the bundles are byte lanes

2020-05-20T22:17:21 < zyp> each byte lane consists of 8 data lines, a byte enable line and a differential strobe line (DQS), i.e. 11 signals in total
2020-05-20T22:19:04 < zyp> on the fpga, there are a bunch of DQS groups, i.e. a group of 16 pins where two of them can run the differential DQS lines and the remaining 9 signals can arbitrarily be mapped to the remaining 14 pins
2020-05-20T22:19:38 < zyp> there's some timing functionalities that requires keeping all the signals for each lane in a group each
2020-05-20T22:20:25 < zyp> I need 8 byte lanes and this fpga also got 8 groups so I don't have a lot of leeway in how I set that up
2020-05-20T22:21:24 < zyp> and then once those are in place, I also need the address and command lines which will be another 33 signals or so
2020-05-20T22:21:37 < jpa-> zyp: maybe you should rotate the chip 180 deg, for some extra challenge
2020-05-20T22:22:05 < zyp> jpa-, why?
2020-05-20T22:22:16 < jpa-> too easy otherwise ;)
2020-05-20T22:22:22 < qyx> such bga
2020-05-20T22:22:45 < qyx> zyp: will you do mp1+ddr3 for me?
2020-05-20T22:22:59 < qyx> or should I kicad it
2020-05-20T22:23:15 < zyp> jpa-, rotating the chip 180 degrees wouldn't affect routing the memory much, I'd just reverse the order of the byte lanes to match
2020-05-20T22:23:58 < jpa-> hmph
2020-05-20T22:24:34 < zyp> the difference is just in whether I want the other generic IO towards the ram or the SERDES towards the ram
2020-05-20T22:26:05 < zyp> I've opted for the latter, I'm planning to do most of the DDR routing and length matching on the bottom layer, leaving the top layer free to route the serdes signals away from the fpga

2020-05-20T22:27:21 < zyp> bottom side is what's currently facing the ram
2020-05-20T22:28:56 < zyp> not entirely sure what I'll hook up at the top yet, I figure at least one ULPI transceiver, maybe two, maybe RGMII, maybe a PMOD or two
2020-05-20T22:29:35 < zyp> maybe microsd, that'd probably be useful
2020-05-20T22:34:42 < zyp> qyx, why are you doing your own instead of going with the seeed SOM?
2020-05-20T22:41:29 < qyx> I am not doing anything yet
2020-05-20T22:41:37 < qyx> yeah I have seen that one
2020-05-20T22:42:29 < zyp> I haven't looked too hard at it, so I don't know what disadvantages it got
2020-05-20T22:42:35 < zyp> hence the question
2020-05-20T22:43:56 < qyx> I just saw it, didn't investigate it further
2020-05-20T22:44:43 < zyp> hmm, maybe that thing would be suitable for the EV charger project I were working on
2020-05-20T22:46:15 < zyp> could probably replace the entire F407 on the mainboard of the EV charger, run the logic on the M4 core and the UI/networking on the A7
2020-05-20T22:48:27 < zyp> I should grab the evalboard some time
2020-05-20T22:49:04 < qyx> 34579-230 is that guide rail you want to use?
2020-05-20T22:51:59 < qyx> the accessory type would fit even if the connector is kept as is
2020-05-20T22:52:06 < qyx> but accessory guide rails are 100mm+
2020-05-20T22:52:44 < qyx> standard type is 70mm+

2020-05-21T02:03:28 < Mangy_Dog> npoe just 2
2020-05-21T02:03:57 < zyp> modifying a 2L design for 4L should be easy, just start by dropping a ground plane and maybe a power plane in the inner layers, all the current ground and power vias should then automatically connect
2020-05-21T02:04:32 < zyp> and then you already have a more robust design
2020-05-21T02:05:09 < Mangy_Dog> im not that bothered tbh its all done
2020-05-21T02:05:16 < zyp> :p
2020-05-21T02:07:00 < zyp> that's a fairly crazy amount of small boards in that layout btw
2020-05-21T02:07:09 < zyp> doesn't jlcpcb charge extra for that?
2020-05-21T02:07:30 < Mangy_Dog> normally
2020-05-21T02:07:38 < Mangy_Dog> but i have a few borus traces running between them
2020-05-21T02:07:43 < Mangy_Dog> if you run traces they dont charge
2020-05-21T02:07:54 < zyp> haha
2020-05-21T02:09:38 < zyp> looks crazy anyway, will you be stacking them together in some 3d puzzle shape, or do they connect with cables?
2020-05-21T02:10:10 < Mangy_Dog> cables mostly
2020-05-21T02:10:14 < Thorn> what's the point of designing boards if you're going to have lots of chinawires running between them as if it were a breadboard prototype?
2020-05-21T02:10:18 < Mangy_Dog> one fpc

2020-05-21T03:07:03 < lux> around 10m2 which is 8-10kw will set you back 3-4k from what i see for warm water
2020-05-21T03:07:21 < lux> and solar is less than 50c per watt
2020-05-21T03:07:24 < lux> so not much difference
2020-05-21T03:08:21 < lux> if you count in the inverter it's a factor 2 i guess
2020-05-21T03:12:24 < zyp> less than 50c/W for the panel itself, sure

2020-05-21T03:49:46 < zyp> depends a lot
2020-05-21T03:50:07 < zyp> my estimates said 4-5 years breakeven
2020-05-21T03:50:18 < zyp> although I don't know how realistic they are :)
2020-05-21T03:50:41 < englishman> just in my little village, there are 14 installations

2020-05-21T03:52:18 < zyp> two of them being houses in my row with identical exteriors, so their production numbers should translate well to what I'm going to install

2020-05-21T03:53:38 < zyp> that it hasn't doesn't necessarily mean it's not going to

2020-05-21T03:54:05 < zyp> my 4-5 year figure assumed unchanged prices

2020-05-21T03:54:17 < englishman> they estimate on a 20 year lifecycle that they will generate at a cost of 15c/kWh but we only pay 7-9c
2020-05-21T03:54:24 < zyp> lately they've been going down
2020-05-21T03:54:31 < englishman> there are some that are profitable at <7c
2020-05-21T03:55:11 < zyp> part of the thing here is that it's possible to sell at a subsidized rate that's actually higher than what you buy for

2020-05-21T03:56:08 < zyp> still possible, apparently

2020-05-21T03:59:57 < zyp> I thought electricity would be like 0.6-0.7 NOK with all fees included
2020-05-21T04:00:27 < zyp> last month I paid .376 NOK/kWh

2020-05-21T04:03:00 < zyp> I think maybe there's some COVID related price cuts in there too
2020-05-21T04:04:08 < zyp> hmm, no
2020-05-21T04:04:24 < zyp> fees have been the same all year
2020-05-21T04:05:32 < zyp> March was .41 NOK/kWh, Feb was .45 NOK/kWh, Jan was .55 NOK/kWh
2020-05-21T04:08:05 < zyp> right, they changed it at newyears, reducing fees per kWh, increasing fixed monthly fees instead
2020-05-21T04:08:22 < zyp> that's why it's so much less per kWh than it used to be

2020-05-21T10:30:31 < qyx> yeah, you can get panels for 120e and even less

2020-05-21T12:00:36 < zyp> qyx, we're talking about grid tie, not battery
2020-05-21T12:02:32 < zyp> qyx, IIRC in my estimate the inverters costs a bit less than the panel
2020-05-21T12:04:46 < zyp> for simplicity I'm planning to do quad-input microinverters mounted along with the panels themselves, so there won't be a need for an electrical cabinet or anything, just run a cable directly to the normal breaker box for the house
2020-05-21T12:08:41 < zyp> it also reduces the requirement for a licensed electrician, since each panel will have its own inverter channel, there won't be any high voltage DC anywhere, and the inverters plug into a premade AC bus cable, so all you need an electrician for is to connect the AC supply to the end of the bus cable

2020-05-21T13:00:58 < catphish> how do you plug into the grid? do you just get a special meter installed with 3 ports?
2020-05-21T13:01:22 < catphish> then your inverters sync to the grid and push current?
2020-05-21T13:01:55 < qyx> zyp: are you able to get 1kVA microinverter for 400e?
2020-05-21T13:17:58 < qyx> naming can0 as can1 in devicetree can waste some time and create surprises
2020-05-21T13:23:09 < zyp> qyx, yes
2020-05-21T13:23:53 < zyp> looking at it, I was quoted €220 for a quad inverter
2020-05-21T13:24:14 < zyp> just the inverter itself
2020-05-21T13:24:47 < qyx> mhm, not bad
2020-05-21T13:25:12 < qyx> it would be great for offgrid too if there were inverters with dc output
2020-05-21T13:25:31 < qyx> ie. basically cheap configurable cc-cv power supplies
2020-05-21T13:25:55 < zyp> or if you have a bidirectional AC/DC converter for the battery
2020-05-21T13:26:23 < zyp> e.g. you could have the battery with AC/DC act as the grid and run standard grid tie inverters on it
2020-05-21T13:26:25 < qyx> such thing cannpot work on its own
2020-05-21T13:26:41 < qyx> yes, but you cannot charge the batteries
2020-05-21T13:26:48 < zyp> how so?
2020-05-21T13:27:06 < qyx> or you can?
2020-05-21T13:27:28 < qyx> dc-ac is making your 230V, microinverters are feeding more power
2020-05-21T13:27:33 < qyx> and ac-dc charger fires
2020-05-21T13:27:38 < qyx> hm, yeah, it could work probably
2020-05-21T13:27:45 < zyp> I figure as long as it maintains frequency lock regardless of whether it's charging or inverting, it'll work
2020-05-21T13:27:57 < qyx> but meh because dc->ac->dc
2020-05-21T13:29:27 < zyp> if you just wanna do dc, a microinverter doesn't really have to be any more than a buck or a boost depending on panel topology and bus voltage
2020-05-21T13:34:35 < qyx> yes
2020-05-21T13:34:40 < qyx> but no such thing readily available
2020-05-21T13:34:49 < qyx> I want to design something
2020-05-21T13:34:57 < qyx> there is SPV1020 for exactly that purpose
2020-05-21T13:36:08 < zyp> the fet gate driver we're using to drive the solenoid fets in workstuff is originally designed for solar stuff as well
2020-05-21T13:39:42 < zyp> https://www.ti.com/lit/ds/symlink/sm72295.pdf <- this thing
2020-05-21T13:42:14 < zyp> we're using them to drive two intependent half bridges instead of one full bridge though
2020-05-21T13:46:20 < zyp> SPV1020 looks like it's designed for those «optimizers»
2020-05-21T13:46:41 < zyp> i.e. to be used together with a traditional string topology
2020-05-21T13:47:25 < qyx> better would be probably to step it up with full-bridge+transformer to some standard voltage, eg. 400Vdc
2020-05-21T13:47:33 < qyx> and connect in parallen
2020-05-21T13:47:45 < zyp> instead of putting all the panels directly in series in a string, you put an optimizer on each panel to get individual MPPT and then put the optimizers in series in a string and feed it to a traditional string inverter

2020-05-21T16:09:54 < englishman> the canadian government makes one called RETscreen

2020-05-21T16:11:58 < englishman> https://www.suncalc.org/ is also pretty neat

2020-05-21T16:19:14 < Laurenceb> yeah but you want weather and stuff at the same time

2020-05-21T16:43:03 < Thorn> I take it you can't route traces on split plane layers in Altium Disaster?
2020-05-21T16:43:13 < dongs> thankfully no
2020-05-21T16:43:20 < dongs> makes you not lazy
2020-05-21T16:43:55 < Thorn> what do you mean thankfully, what if I want to connect a power polygon to my dc/dc which is not sitting on top of that polygon
2020-05-21T16:44:42 < zyp> I don't bother with plane layers, easier to just throw a couple of polygons on a normal inner layer
2020-05-21T16:44:42 < dongs> ?
2020-05-21T16:45:00 < dongs> Thorn: picture please, i dont understand
2020-05-21T16:45:02 < Thorn> i.e. if you use a pmic then all your voltages originate in the same place
2020-05-21T16:45:03 < dongs> zyp, plane layers are great
2020-05-21T16:45:18 < dongs> thorn, you know you can use lines to split the planes right
2020-05-21T16:45:21 < dongs> pl or whatever
2020-05-21T16:45:28 < dongs> and then assign them to different nets
2020-05-21T16:45:38 < zyp> he said split plane layer
2020-05-21T16:45:50 < Thorn> yes and I can draw a thin long appendage that looks like a trace but without the convenience of a trace
2020-05-21T16:45:54 < zyp> but yeah, the solution is obviously to reshape the polygon to get it under the PMIC
2020-05-21T16:47:00 < zyp> dongs, what'cha think about my ddr3? https://bin.jvnv.net/file/xnHGI.png
2020-05-21T16:47:44 < dongs> saw
2020-05-21T16:47:46 < dongs> this mroning
2020-05-21T16:47:51 < Thorn> why do you need a whole dimm
2020-05-21T16:48:17 < zyp> because half-dimms are more expensive?
2020-05-21T16:48:31 < Thorn> is it easier to route than a couple onboard ICs?
2020-05-21T16:48:57 < zyp> that presumably depends on how many «a couple» is
2020-05-21T16:50:14 < Thorn> anyway the most interesting question is what your design rules are and where you're going to order that pcb from
2020-05-21T16:50:24 < Thorn> and how much it's going to cost lol
2020-05-21T16:50:38 < dongs> you cazn't afford it Thorn
2020-05-21T16:50:47 < dongs> well, or you can but you';ll wait 3 months for it

2020-05-21T16:51:41 < zyp> I'm designing within jlcpcb capabilities
2020-05-21T16:52:37 < Thorn> 0.127mm like on their capabilities page or 3.5/3.5mil?
2020-05-21T16:53:34 < zyp> dunno yet, so far I'm working with 5/5
2020-05-21T16:53:47 < zyp> easier to make them thinner later than to make them thicker
2020-05-21T16:53:50 < Thorn> the bga is 1mm?
2020-05-21T16:53:53 < zyp> 0.8
2020-05-21T16:54:00 < zyp> vias are 0.2/0.4
2020-05-21T16:56:08 < zyp> hmm, digikey got some 2GB DDR3 chips: https://www.digikey.com/product-detail/en/issi-integrated-silicon-solution-inc/IS43TR16K01S2AL-125KBL/706-IS43TR16K01S2AL-125KBL-ND/11568750
2020-05-21T16:56:11 < lux> qyx: no need on calling bullshit ;) also you don't need a battery which of course is the most expensive part
2020-05-21T16:56:50 < zyp> costs as much as an 8GB DDR3 SODIMM though
2020-05-21T16:56:52 < lux> and storing thermal energy is pretty cheap, if you are going for that. all you need is water
2020-05-21T16:56:59 < zyp> and I'd need four of those to match
2020-05-21T16:58:05 < zyp> the reason I'm doing a SODIMM socket is partly price, partly complexity
2020-05-21T16:58:50 < englishman> lux: the tanks and glycol add up surprisingly fast. certainly not as fast as batteries but it isn't insignificant
2020-05-21T17:00:04 < lux> yeah i guess if you add it up it costs quite a bit, especially if professionally made
2020-05-21T17:00:25 < jpa-> zyp, Thorn: 4/4 works fine with jlcpcb, but if you layout the whole board with 3.5/3.5 they refuse it
2020-05-21T17:00:29 < lux> but i was more on the side of comparing thermal solar to pv, where the storage aspect is pretty much the same
2020-05-21T17:00:45 < lux> so you end up with that cost either way
2020-05-21T17:00:52 < zyp> jpa-, good to know
2020-05-21T17:01:56 < zyp> 5/5 is already narrower than I usually do
2020-05-21T17:05:52 < zyp> hmm, jlcpcb calc gives me 53.62 ohm for a single ended 5 mil trace
2020-05-21T17:06:10 < zyp> so I'm not even sure I would want to go narrower
2020-05-21T17:07:56 < zyp> 5/5 is also 91.27 ohm differential, so I think it'll work reasonably well for the differential stuff too

2020-05-21T17:28:58 < dongs> and no fuckign way to undo it other than close them all
2020-05-21T17:29:11 < Mangy_Dog> ohhh
2020-05-21T17:29:35 < Mangy_Dog> its because alitums a professional program and youre clearly doing it wrong?!?
2020-05-21T17:29:39 < Mangy_Dog> :p

2020-05-21T17:39:13 < Mangy_Dog> :D
2020-05-21T17:40:05 < Mangy_Dog> but then the Ai develops a wicked sense of humor and then make a super complicated pcb design with thousands of analogue componants.... simple to replicate blink
2020-05-21T17:40:57 < Thorn> then you picture your salary and the AI collects and spends it however it wants

2020-05-21T17:44:07 < Cracki> lots of UI in a GUI can just fuck off until it's actually needed. context sensitive UI seems to be a hard problem that only moneyed companies can solve
2020-05-21T17:44:15 < Cracki> altium must be poor
2020-05-21T17:45:45 < Thorn> overlapping windows was a disastrous idea
2020-05-21T17:45:51 < Thorn> tiling only
2020-05-21T17:45:59 < Thorn> is the way

--- Day changed Fri May 22 2020
2020-05-22T00:00:02 < jadew> well, I wouldn't say it like that hehe
2020-05-22T00:00:18 < aandrew> just say "other products"
2020-05-22T00:05:30 < jadew> yeah, I'll find a way to beat around the bush
2020-05-22T00:05:45 < jadew> it's a product you own :P (that should narrow it down)
2020-05-22T00:08:42 < Ultrasauce> hate it when my dildo makes my radio stuff not work
2020-05-22T00:09:19 < jadew> similar issue here, but with an intermediary, which is this product
2020-05-22T00:10:37 < jadew> it's a signal generator - and I won't mention which :P (see what I did?)
2020-05-22T00:11:31 < jadew> which picks up random signals better than a radio, amplifies them and puts them out of the output port
2020-05-22T00:12:50 < jadew> that, in tandem with horrific harmonics - which is what this customer thought was happening (he though my device was having problems dealing with the harmonics of his sig gen)
2020-05-22T00:13:26 < jadew> but in fact, the sig gen was outputting not only that horrendous signal, but also the amplified wifi signal from his home
2020-05-22T00:15:36 < jadew> anyway, I think I'll just give up on the subject, seems silly to explain this crap
2020-05-22T00:16:28 < BrainDamage> the procedure to debug the problem remotely might be interesting on its own
2020-05-22T00:16:41 < jadew> it took days
2020-05-22T00:17:02 < jadew> good thing the guy was willing to do it and had the tools for it

2020-05-22T00:20:38 < jadew> I guess it could have been faster, but these things to tend span across several days because the communication is done over e-mail

2020-05-22T00:22:05 < jadew> eh, I guess he had other stuff to do too

2020-05-22T00:53:59 < karlp> anyone remember what the Pxx means in pogopins? P50 vs P75 vs P100?  the next letters are the tip shape.
2020-05-22T00:54:21 < englishman> pitch?
2020-05-22T00:54:32 < jadew> it's the size of the tip
2020-05-22T00:54:55 < jadew> actually it's the general size
2020-05-22T00:55:05 < jadew> because the following letters might have different sizes I think
2020-05-22T00:56:30 < qyx> P75 is 75 furlongs wide
2020-05-22T00:56:47 < jadew> P50 = 0.48 dia for the needle tip, 0.9 dia for all the other ones
2020-05-22T00:57:21 < jadew> P75 = 0.66 dia for the needle tip (basically the neck dia), 1.3 for the other ones
2020-05-22T00:57:38 < jadew> P100 = 1 / 1.5
2020-05-22T00:57:52 < jadew> but then you have variations...
2020-05-22T00:58:14 < jadew> based on the tip
2020-05-22T00:58:45 < jadew> ok, nvm about the "other tips"
2020-05-22T00:59:24 < jadew> aha, found more notes
2020-05-22T01:00:39 < jadew> let me make sense of them
2020-05-22T01:02:06 < jadew> ok, so you have 3 sizes for each type
2020-05-22T01:02:29 < jadew> P50 = 0.68 dia, with 0.48 for the neck
2020-05-22T01:02:56 < jadew> P75 = 1.02 dia with 0.74 for the neck
2020-05-22T01:03:27 < jadew> P100 = 1.36 dia with 1 for the neck
2020-05-22T01:04:03 < jadew> the first kind of tip, is the one that is the needle tip, which will have the diameter of the neck (obviously)
2020-05-22T01:04:07 < jadew> and then you have two more sizes
2020-05-22T01:05:41 < jadew> P75-A2, means P75, tip of type A, size 2
2020-05-22T01:07:48 < zyp> Thorn, because that's what you have your rules set up to do

2020-05-22T02:18:04 < karlp> so... dongs, arbiter of professionalism, recommends P75 pogos, which are... fat? I mean, solid, but 1mm shank/body diameter means pretty serious mounting holes too
2020-05-22T02:18:09 < karlp> I think p50 is the way.

2020-05-22T02:22:15 < jadew> karlp, P50 are flimsy
2020-05-22T02:22:28 < jadew> but if you don't have enough room, sure
2020-05-22T02:23:07 < karlp> sure, I guess it depends whether you have extra guides or whether the pins are it.
2020-05-22T02:23:50 < jadew> yeah, it's also the fact that the bigger ones will allow for some error (for example if they're slightly bent)
2020-05-22T02:24:05 < karlp> well, that'ðs also the tip choice. but yeah
2020-05-22T02:24:16 < jadew> P50 will need very tiny holes, otherwise they'll go through (unless you'll have surface pads)
2020-05-22T02:24:33 < karlp> I'm targetting existing board, not really designed for manufacturing, at least, not manufacturing_test_
2020-05-22T02:24:35 < jadew> and if they're slightly bent, it will be difficult to mate with them
2020-05-22T02:24:39 < karlp> what doyou mean very small holes?
2020-05-22T02:24:50 < jadew> are you going to use test points or holes?
2020-05-22T02:25:01 < karlp>  I think Bx tips are dumb, I'm only looking at LM or similar
2020-05-22T02:25:19 < karlp> LM/T/E series look most viable for good mounting
2020-05-22T02:25:28 < karlp> I have holes to target, not pads.
2020-05-22T02:25:38 < karlp> three holes at 2.54mm spacing
2020-05-22T02:25:49 < jadew> right, I'm using LM2 I think, on my programming thing

2020-05-22T02:26:15 < karlp> so I guess, P75 for strenght, with D, E, T or LM tips would be suitable

2020-05-22T02:26:43 < jadew> what I meant about the P50 ones is that the tips will be tiny too
2020-05-22T02:27:14 < jadew> so the holes will also be adequate and they might miss the hole
2020-05-22T02:27:30 < jadew> the bigger ones will allow for more tolerance
2020-05-22T02:27:46 < jadew> but if the board is already designed it doesn't matter I guess
2020-05-22T02:27:46 < karlp> well, P50/E3 is 1.2mm, so not tiny...
2020-05-22T02:27:50 < jadew> just go with whatever fits
2020-05-22T02:27:56 < karlp> target board is already done, yeah
2020-05-22T02:28:31 < jadew> the E tip is the rounded conical one?

2020-05-22T02:35:42 < jadew> no, it's not, it's a good idea
2020-05-22T02:35:48 < jadew> I got a bunch of them for the same reason
2020-05-22T02:36:10 < jadew> I like the LM head
2020-05-22T02:36:18 < jadew> best contact I think
2020-05-22T02:36:46 < jadew> P75-LM2 is the best option IMO
2020-05-22T02:37:33 < karlp> that's exactly what dongs says :)(
2020-05-22T02:37:41 < jadew> heh
2020-05-22T02:37:47 < karlp> lm2 I guess works well for multipoint contact,
2020-05-22T02:37:59 < karlp> E series will get like one poitn if misaligned
2020-05-22T02:38:06 < jadew> yeah
2020-05-22T02:38:08 < karlp> 05:00 < dongs> the ones you want are called P75-LM2
2020-05-22T02:39:16 < jadew> I'd look at the ones with the spiked head too
2020-05-22T02:39:23 < jadew> they're probably good for test points
2020-05-22T02:39:31 < jadew> (if you have those)
2020-05-22T02:39:47 < karlp> H and Q? yeah, for test points those look good
2020-05-22T02:40:04 < karlp> and F I guess
2020-05-22T02:40:35 < karlp> A looks like you're really trying to get some serious current over the pins
2020-05-22T02:40:44 < Laurenceb> englishman: I simulated ur greenhouse in TNSYS
2020-05-22T02:40:47 < bitmask> ohhhhhhhh shit
2020-05-22T02:41:01 < Laurenceb> its kind of cool, like a freewarez simulink for building stuff
2020-05-22T02:41:10 < jadew> karlp, yeah, not sure what's the deal with A, it could be just for board support
2020-05-22T02:41:10 < bitmask> ive been using an old version of altium 18, I finally found 20
2020-05-22T02:41:13 < Laurenceb> *construction and chemical engineering design
2020-05-22T02:41:31 < jadew> karlp, you can actually get some really beefy ones with the same head type (I did)
2020-05-22T02:41:43 < Laurenceb> I dont have any raw data for Canada in the built in libraries :(
2020-05-22T02:41:59 < karlp> hrm, that makese sense too I guess, mount a few around just to hold it, but really? why use a different type?
2020-05-22T02:42:11 < karlp> if you're hoping for less scratches?
2020-05-22T02:42:16 < karlp> seems niche+
2020-05-22T02:42:34 < jadew> they have a bigger area of contact
2020-05-22T02:42:43 < karlp> oir that's me being naiive and drastically underestimating lifetime oif test fixtures
2020-05-22T02:42:52 < karlp> bigger contact if well aligned, yeah
2020-05-22T02:42:53 < Laurenceb> englishman: looks like maintaining +30C with solar is really hard, at least in north central Romania, which I used as a substitute for Canada
2020-05-22T02:43:05 < karlp> so, good for bord support.
2020-05-22T02:43:06 < jadew> also, you can get some for screw holes
2020-05-22T02:43:19 < karlp> jadew: thanks for listening :)
2020-05-22T02:43:23 < jadew> so they fit in the screw holes, for the same reason
2020-05-22T02:43:27 < jadew> heh, np :)
2020-05-22T02:43:53 < karlp> now, what _lengths_ do they come in?
2020-05-22T02:43:59  * karlp pulls out the board in question
2020-05-22T02:44:02 < Laurenceb> englishman: but if you shut down for 4 weeks/year, in December and beginning of Jan, its not so bad at all
2020-05-22T02:44:12 < karlp> and wonders why the fuck he's measuring a work board at midnight on a holiday
2020-05-22T02:44:34 < jadew> you can offset them if they're different lengths
2020-05-22T02:44:54 < karlp> just thinking abotu the mounting of it all
2020-05-22T02:45:13 < jadew> there are some sockets you can put them in
2020-05-22T02:45:24 < jadew> and the sockets come with stops at different offsets :P
2020-05-22T02:46:15  * karlp needs 27.5mm from base board to target point

2020-05-22T03:05:21 < mawk> just the wonderful awesome super TV would've been ok englishman 
2020-05-22T03:05:28 < karlp> I wonder if the tv remebers or if it's had too much peppa pig since then
2020-05-22T03:05:40 < mawk> but then the health insurance took 800€ at once while they told me they would take it over several months
2020-05-22T03:09:03 < Laurenceb> keeekk now the muricans have no food
2020-05-22T03:09:06 < Laurenceb> epic lulz
2020-05-22T03:09:10 < Cracki> eh
2020-05-22T03:09:25 < Laurenceb> massive queues and nothing to eat apparently
2020-05-22T03:09:30 < Cracki> yay
2020-05-22T03:09:34 < Cracki> engineered famine
2020-05-22T03:09:44 < Cracki> we had that ~88 years ago
2020-05-22T03:09:51 < Cracki> (not we we, general we)
2020-05-22T03:10:27 < jadew> Laurenceb, got a link for that?
2020-05-22T03:10:31 < jadew> it seems troubling
2020-05-22T03:10:43 < Cracki> this is the first link I clicked: https://foreignpolicy.com/2020/05/06/coronavirus-usa-meat-food-supply-chain/
2020-05-22T03:10:47 < Laurenceb> just watching bbc news

2020-05-22T03:11:25 < Cracki> in europe you don't have megafarms and it seems they aren't all owned by megacorps
2020-05-22T03:11:54 < jadew> ah, so it's just about beef
2020-05-22T03:11:56 < Cracki> >crisis in processing, not supply
2020-05-22T03:12:22 < Cracki> yes, you can buy whole cows and butcher them yourself but the slaughter houses seem to be closing because someone sneezed

2020-05-22T03:14:23 < mawk> Mangy_Dog: what did he invent ?
2020-05-22T03:14:39 < Cracki> nvm, it's some tv show producer or something
2020-05-22T03:14:51 < Cracki> and "wipes" seem to be a vlog format of his
2020-05-22T03:14:55 < jadew> yeah
2020-05-22T03:15:01 < jadew> that's what the comments are implying
2020-05-22T03:15:06 < Cracki> ¯\_(ツ)_/¯ brit culture doesn't leave the island
2020-05-22T03:15:34 < jadew> too bad it's not something important, because I just got a sore
2020-05-22T03:15:37 < jadew> sore throat
2020-05-22T03:15:39 < Cracki> heh
2020-05-22T03:15:50 < jadew> it developed like 3 hours ago
2020-05-22T03:15:59 < jadew> maybe 4
2020-05-22T03:16:06 < jadew> I hope it's just a cold
2020-05-22T03:16:10 < Cracki> president orange commanded everyone to chug bleach for the inner cleansing effect
2020-05-22T03:16:11 < mawk> then it's been 2 days you're contaminating everyone
2020-05-22T03:16:37 < Cracki> even if it's the plague, you'll survive with 99.8% probability
2020-05-22T03:16:53 < Cracki> maybe do drink some alcohol
2020-05-22T03:16:54 < jadew> yeah, but I visited my grandmother yesterday, I had to do a supply run
2020-05-22T03:17:02 < Cracki> rip grandma
2020-05-22T03:17:06 < jadew> I wore two masks tho
2020-05-22T03:17:13 < Cracki> that's like wearing two condoms
2020-05-22T03:17:19 < jadew> FFP2 + surgical
2020-05-22T03:17:24 < mawk> why
2020-05-22T03:17:26 < Cracki> did she tho
2020-05-22T03:17:29 < mawk> just wear the first
2020-05-22T03:17:39 < jadew> mawk, the FFP2 I have has a valve
2020-05-22T03:17:40 < mawk> with two condoms is slips against each other and comes off
2020-05-22T03:17:43 < mawk> ah
2020-05-22T03:17:46 < mawk> mine too
2020-05-22T03:17:53 < mawk> but fuck the others right, let's just use it like that
2020-05-22T03:18:03 < mawk> just joking, don't turn me in
2020-05-22T03:18:13 < jadew> thing is, I was super careful
2020-05-22T03:18:17 < jadew> and whatever this is, I got it
2020-05-22T03:18:21 < jadew> and I don't understand how
2020-05-22T03:18:33 < jadew> I must have changed 5 pairs of gloves while I was there
2020-05-22T03:18:41 < jadew> and several more on the way there
2020-05-22T03:18:41 < Cracki> if he breathes he's a superspreader
2020-05-22T03:18:42 < mawk> you're too paranoid
2020-05-22T03:18:55 < mawk> don't take that many precautions
2020-05-22T03:19:04 < mawk> just what it takes
2020-05-22T03:19:04 < jadew> well, that's the thing
2020-05-22T03:19:21 < jadew> I took so many precautions and I still have a runny nose and a sore throat
2020-05-22T03:19:25 < Cracki> it's like trees in a forest. if this storm doesn't blow them over, the next one will.
2020-05-22T03:19:26 < mawk> you brought it in your home on your pĥone, your clothes
2020-05-22T03:19:35 < Cracki> ^
2020-05-22T03:19:45 < mawk> or your grocery bags
2020-05-22T03:19:45 < jadew> I have a strict protocol with clothes
2020-05-22T03:19:52 < jadew> and I don't answer the phone while out
2020-05-22T03:19:53 < Cracki> nothing short of an airtight hazmat suit will do
2020-05-22T03:20:00 < mawk> or it got into your eyes when you were outside
2020-05-22T03:20:08 < jadew> grocery bags go straight on the balcony where they sit for a while
2020-05-22T03:20:16 < jadew> then everything gets disinfected with alcohol
2020-05-22T03:20:23 < mawk> ah
2020-05-22T03:20:27 < mawk> you don't have to do both
2020-05-22T03:20:34 < mawk> do alcohol for fresh thing, let sit for 2 days for non-fresh
2020-05-22T03:20:39 < Cracki> these face masks are a fig leaf. they prevent nasty pigs from coughing their sputum at you, but that's it
2020-05-22T03:20:48 < jadew> the eyes route might be what did it, I forgot my glasses two days ago when I went into a fucking hardware store
2020-05-22T03:20:51 < jadew> which was packed
2020-05-22T03:20:52 < mawk> the surgical masks don't even Cracki 
2020-05-22T03:20:58 < mawk> it's mainly for you to not contaminate other
2020-05-22T03:21:03 < jadew> I didn't stay in line, I just put my shit back on the shelves and left
2020-05-22T03:21:04 < mawk> or is it what you meant ?
2020-05-22T03:21:24 < Cracki> right, I assumed that these rules would reach nasty pigs and get them to wear masks
2020-05-22T03:21:46 < jadew> yeah, that's the idea behind the surgical masks
2020-05-22T03:21:50 < Cracki> I once had to watch a grown fucking adult dig in his nose and... do what toddlers do
2020-05-22T03:21:58 < Cracki> (was years ago)
2020-05-22T03:21:59 < mawk> lol
2020-05-22T03:22:17 < Cracki> and he got mad when someone told him to stop that
2020-05-22T03:22:38 < Cracki> he managed to get a bachelor's in computer science
2020-05-22T03:22:41 < jadew> his buggers
2020-05-22T03:22:44 < Laurenceb>  "Mr Trump, why don't you wear the mask" 
2020-05-22T03:22:50 < Laurenceb> this is getting quite memetic
2020-05-22T03:22:53 < Cracki> boogers*
2020-05-22T03:22:58 < jadew> maybe he already had corona
2020-05-22T03:23:07 < jadew> or already got the vaccine
2020-05-22T03:23:08 < Cracki> bugger ~ fucker. buggery is sodomy.
2020-05-22T03:23:25 < Laurenceb> spmething Cracki knows all about
2020-05-22T03:23:43 < Cracki> your shoe laces are untied
2020-05-22T03:24:47 < Cracki> our alleged politicians don't wear masks either... one minute for the photo op, then they rip them off
2020-05-22T03:25:37 < Laurenceb> I think my laptop is dying
2020-05-22T03:25:37 < Cracki> back to pogo pins
2020-05-22T03:25:44 < Cracki> I got P50 and P75
2020-05-22T03:25:47 < Laurenceb> >[62931.988092] Machine check events logged
2020-05-22T03:26:05 < Cracki> P50 because 0.6x mm would kinda fit inside pin strip headers
2020-05-22T03:26:16 < Cracki> P75 because it fits pretty much exactly into TH pads
2020-05-22T03:26:55 < Cracki> 0.65mm squares are ~0.92 mm diagonally
2020-05-22T03:27:03 < mawk> wew I fixed the production server just in time
2020-05-22T03:27:19 < Cracki> so the typical TH pads I see on random boards around me are slightly larger than 0.92mm diameter
2020-05-22T03:27:31 < Cracki> you said 3 hours ago that you'd have 2.5 hours
2020-05-22T03:27:40 < mawk> yeah
2020-05-22T03:27:48 < Cracki> trash ppl had extended breadfast?
2020-05-22T03:27:51 < mawk> I pushed the critical parts 1. hours ago
2020-05-22T03:27:52 < Cracki> *breakfast
2020-05-22T03:27:56 < mawk> 1.5 hours ago*
2020-05-22T03:27:57 < Cracki> what went wrong?
2020-05-22T03:28:01 < mawk> for the trash algorithm thing
2020-05-22T03:28:08 < mawk> then fixed the rest after that
2020-05-22T03:28:14 < Cracki> ic
2020-05-22T03:28:16 < mawk> yesterday we moved from transip to digitalocean
2020-05-22T03:28:28 < mawk> and apparently the mysql version was slightly different
2020-05-22T03:28:43 < Cracki> :<
2020-05-22T03:29:20 < mawk> and
2020-05-22T03:29:37 < Cracki> oh well, yall are not gonna move again any time soon eh
2020-05-22T03:30:03 < mawk> we have the construct: SELECT id, max(c3) FROM t1 WHERE c2 = 'W' GROUP BY id
2020-05-22T03:30:12 < mawk> that seems like an innocuous piece of SQL right
2020-05-22T03:30:18 < Cracki> right
2020-05-22T03:30:25 < Cracki> nothing I wouldn't have written a dozen times
2020-05-22T03:30:35 < mawk> but if you have an index (id, c2, c3) then a loose index scan is performed, per the optimizer rules
2020-05-22T03:30:54 < mawk> and apparently there is a bug or something (mysql 8.0.18) in which not all the rows are considered
2020-05-22T03:30:58 < mawk> and the result is just wrong
2020-05-22T03:31:01 < Cracki> lol
2020-05-22T03:31:03 < mawk> we're filling a bug report tomorrow
2020-05-22T03:31:18 < Cracki> is that a bleeding edge version?
2020-05-22T03:31:24 < mawk> not even
2020-05-22T03:31:32 < jadew> so write the query differently
2020-05-22T03:31:49 < mawk> we had 170 queries with tht construct
2020-05-22T03:31:49 < jadew> or create another index
2020-05-22T03:31:51 < Cracki> it's valid sql, I'd downgrade to a more stable version instead
2020-05-22T03:31:55 < mawk> I changed every single one of them
2020-05-22T03:31:59 < Cracki> wat
2020-05-22T03:32:01 < mawk> we cannot change the version it's a managed sql server
2020-05-22T03:32:12 < mawk> so yeah I just over all of them
2020-05-22T03:32:17 < Cracki> bummer. what did you have to change, just the queries not indices?
2020-05-22T03:32:51 < mawk> yeah I changed as GROUP BY id, c2
2020-05-22T03:33:04 < mawk> and then it's alright
2020-05-22T03:33:15 < jadew> wait, group by id?
2020-05-22T03:33:19 < jadew> wtf stupid query is that?
2020-05-22T03:33:24 < mawk> id is just a column name
2020-05-22T03:33:27 < mawk> it's not the primary key
2020-05-22T03:33:30 < Cracki> group by id I see, but group by c2? that should collapse *everything*
2020-05-22T03:33:31 < jadew> ah
2020-05-22T03:34:00 < mawk> it doesn't change anything Cracki since there's only one value for c2
2020-05-22T03:34:03 < mawk> which is 'W'
2020-05-22T03:34:04 < Cracki> ic
2020-05-22T03:34:09 < Cracki> hm yes sure
2020-05-22T03:34:11 < mawk> it just forces the optimizer to do the right thing
2020-05-22T03:34:20 < Cracki> but are there multiple rows with c2='W' and different ids
2020-05-22T03:34:27 < mawk> yeah
2020-05-22T03:34:46 < mawk> well it groups by the id and also the c2
2020-05-22T03:35:00 < mawk> and the c2 has only one value, so it gives one row per value of id
2020-05-22T03:35:01 < Cracki> oh right, group by id,c2, I thought i'd collapse both, but it collapses to tuples of that
2020-05-22T03:35:08 < jadew> mysql sucks at optimizing the query
2020-05-22T03:35:11 < Cracki> or does it
2020-05-22T03:35:40 < mawk> GROUP BY a, b, c gives card(a)*card(b)*card(c) rows
2020-05-22T03:35:54 < Cracki> phew
2020-05-22T03:35:56 < mawk> I guess
2020-05-22T03:36:01 < mawk> at least for a, b that's what it does
2020-05-22T03:36:07 < Cracki> it must, it seems to work
2020-05-22T03:36:11 < mawk> it groups by values of (a, b)
2020-05-22T03:36:13 < mawk> of the tuple
2020-05-22T03:36:20 < mawk> yeah jadew 
2020-05-22T03:36:37 < mawk> and if I change the WHERE to be a bit more complex then it's the right value
2020-05-22T03:36:55 < mawk> like if it's WHERE c2 = 42 and I change by WHERE c2 > 41 AND c2 < 43, the bug is not triggered
2020-05-22T03:36:59 < jadew> I had to fix a similar issue a couple of weeks ago on a server
2020-05-22T03:37:02 < mawk> so you see it's an optimizer bug
2020-05-22T03:37:07 < mawk> about the index
2020-05-22T03:37:12 < jadew> where a big query was extremely slow
2020-05-22T03:37:29 < mawk> yeah I don't know why we're not use postgresql, presumably too many mysqlisms
2020-05-22T03:37:33 < jadew> everything was properly index, but mysql was deciding for no apparent reason, that it should do a full row scan
2020-05-22T03:37:40 < jadew> on an 8 million rows table...
2020-05-22T03:37:42 < mawk> nice
2020-05-22T03:38:12 < jadew> no matter how I broke that query up to check it separately, it just worked
2020-05-22T03:38:15 < jadew> I couldn't repeat the fault
2020-05-22T03:38:30 < jadew> so I just rewrote it a little and it stopped causing issues
2020-05-22T03:38:44 < jadew> (I broke it into two queries)
2020-05-22T03:39:12 < jadew> I'm not complaining tho
2020-05-22T03:39:12 < mawk> for my problem I tried breaking into two queries just to be sure
2020-05-22T03:39:20 < jadew> I get paid when shit isn't working
2020-05-22T03:39:45 < mawk> SELECT id, MAX(c3) FROM (SELECT id, c2, c3 FROM t1 WHERE c2 = 'W') GROUP BY id;
2020-05-22T03:39:53 < mawk> but the optimizer merges the two queries and the bug is here again
2020-05-22T03:40:01 < jadew> heh
2020-05-22T03:40:09 < jadew> that's actually what fixed my problem
2020-05-22T03:40:26 < mawk> yeah mysql sucks at optimizing apparently
2020-05-22T03:40:30 < mawk> or rather, it's quite non-deterministic
2020-05-22T03:41:05 < jadew> it's the gcc of the compiler world
2020-05-22T03:41:14 < mawk> lol
2020-05-22T03:41:26 < jadew> *of the database world
2020-05-22T03:43:12 < Cracki> how do yall do your beds of nails? I was considering taking the board file of the DUT, write a script to pick out vias and pads and whatnot of relevant signals, and place pogo pin holes in a new board file... then i'd have those pads in the right places and would only need to hook them up to some useful connector and run traces
2020-05-22T03:43:36 < Cracki> I hear most just pick the positions manually
2020-05-22T03:43:55 < englishman> Laurenceb: +30c isnt a requirement
2020-05-22T03:43:58 < Cracki> I think that's more economical given that I'm not doing this all day, no automation needed
2020-05-22T03:44:13 < englishman> as long as it doesn't fall below +5c many plants can thrive

2020-05-22T03:46:04 < Laurenceb> but trying to get all the year at that temp means >120% of floor area required
2020-05-22T03:46:32 < jadew> Cracki, I haven't started making the test jig I have in mind, but I decided to use small boards and 3D print a support for them
2020-05-22T03:46:44 < jadew> for example, I would have one for the general purpose programming header
2020-05-22T03:46:53 < jadew> so I can move that from board to board if I want to
2020-05-22T03:46:55 < Laurenceb> if you can live with a few weeks per year at ~0C and then a few days dropping to 5C or so around then, then 60% of floor area seems ok
2020-05-22T03:47:04 < Cracki> ic, separate boards tied together with a 3d printed frame...
2020-05-22T03:47:07 < jadew> yep
2020-05-22T03:47:21 < jadew> I want to do one for SMA connectors too
2020-05-22T03:47:39 < Cracki> for my purpose a single pcb holding the pogos would be good enough, but I'd STILL need some support around it for alignment maybe, and maybe latching so the user does't have to press down
2020-05-22T03:47:46 < jadew> but I didn't get around to testing its frequency response yet
2020-05-22T03:48:01 < Cracki> :D
2020-05-22T03:48:10 < jadew> I think it will work :)

2020-05-22T03:50:49 < Laurenceb> looks like optimal angle is 65 degrees to horizontal
2020-05-22T03:52:42 < Cracki> is that some complicated calculation or just latitude +- 23.5 deg?
2020-05-22T03:54:03 < Laurenceb> well this sim code has a complex optimiser, but its not hugely sensitive
2020-05-22T03:54:17 < Laurenceb> so yeah, just latitude +23 is close enough
2020-05-22T03:54:42 < Laurenceb> this is kind of cool as a simulink replacement, pity its not opensores
2020-05-22T03:54:46 < Laurenceb>  - TNSYS
2020-05-22T03:54:49 < Cracki> it's probably not high noon in summer because that's losing you in other times, and not high noon in winter because that's worse for summer time
2020-05-22T03:55:47 < Cracki> great now I kinda wanna do this quickly in python
2020-05-22T03:55:50 < englishman> seems low as the sun dips to a lowest low angle of 20deg
2020-05-22T03:56:01 < englishman> but i guess that is when the panels are most needed, too
2020-05-22T03:56:31 < Laurenceb> I set it to optimise for reliability at 60% of floor area and setpoint of 10C

2020-05-22T03:57:10 < Laurenceb> 50% reliability in December, ouch
2020-05-22T03:57:28 < Laurenceb> but 100% from mid Feb to mid Nov
2020-05-22T03:58:09 < Cracki> hmm https://i.ytimg.com/vi/0esRftZ3qdw/maxresdefault.jpg
2020-05-22T03:58:11 < Laurenceb> only seems to go subzero for a few weeks at end of Dec, first week of Jan
2020-05-22T03:59:46 < englishman> what's the reliability at 30C?
2020-05-22T04:00:05 < englishman> we seed in late jan / early feb, but those seeds need to be at 20C+
2020-05-22T04:00:34 < englishman> stuff that could overwinter at those temps are thinks like kale, carrots that can take the frost
2020-05-22T04:00:55 < englishman> but putting seedlings outside asap. would save money and have a larger yield
2020-05-22T04:01:15 < Laurenceb> yeah thats going to need like 80% or 85% of floor area as panels
2020-05-22T04:01:31 < englishman> but at 60%, when does 25C reliability start?
2020-05-22T04:02:17 < Laurenceb> end of first week of March it seems
2020-05-22T04:02:28 < englishman> cool
2020-05-22T04:02:29 < karlp> mawk: if you had to change your sql to get results, hten something's massively fucked

2020-05-22T04:03:53 < karlp> this isn't c with undefined behaviour
2020-05-22T04:04:13 < englishman> you mean a plc
2020-05-22T04:04:35 < strata> all this talk about building greenhouses and stuff has me really excited
2020-05-22T04:05:15 < jadew> karlp, he said there's a bug in that version of mysql
2020-05-22T04:05:54 < Laurenceb> maybe a plc...
2020-05-22T04:05:58 < jadew> from what I understood, it's actually respecting the index, just that it's not ending up with the correct results
2020-05-22T04:06:03 < Laurenceb> https://imagebin.ca/v/5NLGuc7p7o30
2020-05-22T04:06:17 < Laurenceb> needs to follow the logic there.. and turn off when greenhouse is too hot
2020-05-22T04:08:08 < karlp> jadew: missed that, I just saw they were going to file a bug tomorrow?
2020-05-22T04:08:32 < karlp> strata: does it have you warm and humid? or just excited?
2020-05-22T04:08:58 < strata> karlp, all of the above.

2020-05-22T04:09:38 < strata> some greenhouses are using these hanging clear plastic tubes of water because they are closer to the plants
2020-05-22T04:09:46 < strata> and they refract more light around as well as store the heat
2020-05-22T04:10:36 < strata> it makes me wonder how hot does that water get in winter? is it too hot for fish?
2020-05-22T04:10:59 < strata> the water reserviors could double as fish tanks to have aquaponics greenhouse

2020-05-22T14:21:33 < dongs> intel bought killer networks
2020-05-22T14:21:40 < dongs> now even intel nics arent safe from that aids
2020-05-22T14:23:57 < zyp> heh
2020-05-22T14:27:11 < englishman> wtf
2020-05-22T14:27:26 < dongs> does AMD make any NICs that arent shit
2020-05-22T14:27:30 < dongs> or is realtek all thats left
2020-05-22T14:27:39 < englishman> does amd make any nics
2020-05-22T14:27:42 < dongs> i wonder what teh fuck made intel buy that snakeoil garbage
2020-05-22T14:27:55 < dongs> unless they bought it to bury it
2020-05-22T14:28:18 < englishman> are there any engineers left at intel
2020-05-22T14:28:20 < englishman> or just suits

2020-05-22T14:28:50 < englishman> do the world a favor and destroy the drivers, IP, and brand.
2020-05-22T14:29:11 < englishman> lunix, in your wifi card
2020-05-22T14:30:19 < dongs> haha
2020-05-22T14:32:08 < dongs> nah the lunix thing was back when they were called bigfoot networks
2020-05-22T14:32:18 < dongs> after rivet shit all they're doing is applying QoS bits on packets
2020-05-22T14:32:21 < dongs> a lot of good that does
2020-05-22T14:33:49 < zyp> heh
2020-05-22T14:34:27 < englishman> maybe they have proprietary packet sniffing tech that intel wants to add to their data sniffing """""security engine"""""""""
2020-05-22T14:40:04 < dongs> when you add that QoS shit and your typical ISP router gives zero fucks about it
2020-05-22T14:40:13 < dongs> not that it matters cuz nothing on internet cares about your QoS bits either
2020-05-22T14:40:58 < englishman> not true
2020-05-22T14:41:07 < englishman> my cell network deprioritizes voip packets
2020-05-22T14:41:14 < englishman> so they can sell their own voip shit

2020-05-22T14:47:25 < zyp> so far I've managed to fan out all data lanes, all 16 address lines and the two clock lines, but now I'm unsure where I can squeeze in the remaining 13 signals
2020-05-22T14:48:51 < zyp> i.e. 108 signals done, 13 to go
2020-05-22T14:50:54 < zyp> RESET# probably doesn't have very strict requirements apart from the voltage level, so I guess that doesn't count

2020-05-22T15:28:14 < Laurenceb> ideally diffuse and direct sun is needed
2020-05-22T15:46:09 < Laurenceb> looks like this is the reason the sunlight data was missing from TNSYS
2020-05-22T15:46:40 < Laurenceb> no light sensors on Canadian gov weather stations
2020-05-22T15:48:43 < englishman> thats probably in natural resources canada

2020-05-22T15:51:56 < englishman> fun fact: natural resources canada also oversees explosive material
2020-05-22T15:52:07 < englishman> so when you import surplus russian ammo, it has to go through them

2020-05-22T18:44:37 < jadew> while looking at the octave window
2020-05-22T18:44:45 < Cracki> make it dump checkpoints, so you can resume?
2020-05-22T18:44:55 < jadew> well, I didn't think I'd be that dumb
2020-05-22T18:45:12 < jadew> oh well, starting over
2020-05-22T18:45:24 < Cracki> how much time did this not-take off?
2020-05-22T18:45:26 < jadew> was going to calculate how much more till its done, so I can go eat
2020-05-22T18:45:35 < Cracki> now you can go eat, it'll take 100%
2020-05-22T18:45:39 < jadew> haha
2020-05-22T18:45:42 < jadew> yeah
2020-05-22T18:46:17 < Cracki> first day of the year with 25C outside, and it's muggy af. I think I'll skip a meal today
2020-05-22T18:46:42 < jadew> ok... 45 minutes
2020-05-22T18:46:44 < jadew> ttyl
2020-05-22T18:47:41 < PaulFertser> Cracki: but microstepping drivers monitor current, something that sound card can't do unfortunately.
2020-05-22T18:48:40 < bitmask> what kinda glue is E6000
2020-05-22T18:48:40 < Cracki> monitor only to steer it towards the set point
2020-05-22T18:48:45 < PaulFertser> But the idea is worth considering, probably for other usecases. Cheap USB soundcard without DC blocking capacitors + class D; potentially useful.
2020-05-22T18:48:58 < Cracki> aye
2020-05-22T18:49:30 < Cracki> otherwise you'd have to live with 12 bits of DAC on some stm32 and that's just unbearable right :>
2020-05-22T18:50:01 < Cracki> I could see using python to generate the waveforms tho. that's nice and easy.
2020-05-22T18:51:43 < bitmask> if you wire the pot like this, wont you be reading high when the pot is all the way to the left?
2020-05-22T18:52:42 < Cracki> like what?
2020-05-22T18:52:53 < Cracki> anyway yes that's usually how they work
2020-05-22T18:52:54 < bitmask> ohhaha
2020-05-22T18:52:55 < bitmask> https://learn.adafruit.com/assets/27586
2020-05-22T18:53:07 < bitmask> dont you want gnd on the left?
2020-05-22T18:53:14 < Cracki> yes precisely, you get a voltage between gnd and 3.3v on the center leg
2020-05-22T18:53:20 < Cracki> eh, either way
2020-05-22T18:53:34 < bitmask> well if its all the way to the left (turned down) dont you want a low reading?
2020-05-22T18:53:50 < Cracki> I guess if you want it going clockwise, you want the outer legs switched yes
2020-05-22T18:53:58 < bitmask> ok
2020-05-22T18:54:06 < Cracki> it's aidsfruit, I don't expect them to give attention to such details
2020-05-22T18:54:32 < bitmask> i mean it obviously depends on use case but for what I described I'll put gnd on the left
2020-05-22T19:04:13 < bitmask> alright, one more component and this stupid schematic is done
2020-05-22T19:05:08 < bitmask> then I gotta see if I can cleanly do this on 1 layer

2020-05-22T22:04:04 < Thorn> how do you connect the output of a dc/dc on top layer with a plane layer? make a small region or pour on top layer and put a bunch of vias into it?
2020-05-22T22:05:35 -!- catphish [~user@unaffiliated/catphish] has joined ##stm32
2020-05-22T22:06:40 < Cracki> according to that fedevel video, buncha vias
2020-05-22T22:06:41 < qyx> a ~large island of Vout connecting the inductor and the caps together + via with trace to feedback divider
2020-05-22T22:06:52 < qyx> and then do whatever you want with it
2020-05-22T22:07:23 < qyx> large = slightly larger than the pad sizes together
2020-05-22T22:10:00 < Thorn> https://i.imgur.com/kAyrAiT.png lol
2020-05-22T22:12:45 < aandrew> not a fan of that via smack under the inductor but if you're tenting it should be fine
2020-05-22T22:13:07 < Thorn> I'll remove it
2020-05-22T22:13:24 < aandrew> why *is* that via there, you're already connecting the pad right under the pad
2020-05-22T22:13:40 < aandrew> and I assume one of the entire inner layers is ground, so what's that guy doing there
2020-05-22T22:13:48 < aandrew> same with the one way off to the left
2020-05-22T22:14:47 < Thorn> dunno, someone here has taught me to place gnd vias on both sides of gnd pins lol
2020-05-22T22:15:09 < Thorn> layer 2 is a solid gnd plane
2020-05-22T22:18:48 < aandrew> if you don't have a via right on the pad, I'd agree
2020-05-22T22:22:37 < Ultrasauce> isnt via-in-pad a good idea to use pervasively if the process supports it
2020-05-22T22:22:41 < Ultrasauce> to minimize inductance
2020-05-22T22:26:25 < Thorn> is there any way other than vias in center pad for qfns and similar with center pad?

2020-05-23T12:02:25 < Steffanx> Hm
2020-05-23T12:08:17 < qyx> anyone familiar with uboot environment stored in SPI flash?
2020-05-23T12:08:20 < qyx> how does the thing work
2020-05-23T12:23:31 < jpa-> i've messed with a device that did that, seemed to work fine :P
2020-05-23T12:23:41 < jpa-> (it was stored in emmc)
2020-05-23T12:27:03 < qyx> I though it may somewhat corrupt my flash when misconfigured, which is apparently true
2020-05-23T12:27:27 < qyx> but not in this case, I check with no env and it didn't boot
2020-05-23T12:29:54 < qyx> the thing works when using 8M flash with 4k erase block size
2020-05-23T12:30:07 < qyx> and doesn't with 32M flash with 64k erase size
2020-05-23T12:31:16 < qyx> everything works until uboot runs the kernel, then it hangs

2020-05-23T13:19:01 < PaulFertser> qyx: the kernel just hangs? Doing what? Probably it's not really related to uboot env. 
2020-05-23T13:19:24 < PaulFertser> qyx: and if you do not use "save_env" then flash is never written by uboot and so erase block size doesn't matter.

2020-05-23T13:23:03 < qyx> it hangs doing nothing, there is "jumping to kernel code" and thats all
2020-05-23T13:23:18 < PaulFertser> qyx: so it's probably not the kernel hanging
2020-05-23T13:23:26 < qyx> I am using exactly the same images, the same flashing script
2020-05-23T13:23:46 < PaulFertser> How are you flashing, running what?
2020-05-23T13:23:56 < qyx> the only thing changed is one resistor (Selecting internal 8M flash or the external one, 32M)

2020-05-23T13:25:04 < qyx> because at91bootstrap and u-boot both boot
2020-05-23T13:25:07 < qyx> from the same flash

2020-05-23T17:10:59 < Cracki> typical frequencies in weather are 3 orders of magnitude smaller than vibrations
2020-05-23T17:11:01 < Laurenceb> anyway its WYEC2 with merged satellite data for clouds
2020-05-23T17:11:23 < Cracki> so the canadians must have less than 3 orders of magnitude more stations than your one babby shaker

2020-05-23T17:14:05 < Laurenceb> makes me wonder if just some water barrels would help
2020-05-23T17:14:16 < Cracki> plausible
2020-05-23T17:14:36 < englishman> a large thermal mass like a concrete north wall goes a long way
2020-05-23T17:14:36 < Laurenceb> there are hardly any days when it doesnt go above freezing at some point
2020-05-23T17:14:59 < Laurenceb> its just sometimes horribly cold during the night
2020-05-23T17:16:26 < Cracki> haha that space academy's "synthesis" question is an iq test.
2020-05-23T17:18:59 < Laurenceb> wow
2020-05-23T17:19:10 < Cracki> the goldilocks question so far looks like you're supposed to "pareto" it
2020-05-23T17:19:10 < Laurenceb> just adding a fan or two to the ground helps massively
2020-05-23T17:19:17 < Cracki> fan to the ground does what
2020-05-23T17:19:21 < Laurenceb> like no nights below -28C
2020-05-23T17:19:39 < Laurenceb> circulates the air
2020-05-23T17:19:44 < Cracki> that's all?
2020-05-23T17:19:49 < Laurenceb> I think just some barrels will help a lot
2020-05-23T17:19:51 < Laurenceb> yeah
2020-05-23T17:19:52 < Cracki> what does that do
2020-05-23T17:20:00 < Laurenceb> stops a cold layer acculumating
2020-05-23T17:20:14 < Cracki> where do you measure, and where is it warmer that circulation brings that around?
2020-05-23T17:20:15 < BrainDamage> it's also a smol source of heat
2020-05-23T17:20:31 < Laurenceb> bet you can keep it above -10C with barrels 
2020-05-23T17:20:42 < Laurenceb> they will drive convection and store heat
2020-05-23T17:23:15 < Laurenceb> yeah a 220L water barrel per 3m^2 keeps it above -20C
2020-05-23T17:24:07 < Laurenceb> above 0C all the time by March

2020-05-23T18:28:13 < Cracki> apa102 _maybe_, the datashit gives no minimum supply voltage
2020-05-23T18:30:16 < Cracki> not sure why it's got a regulator output and what it's for. regulator wants 4.5v minimum
2020-05-23T18:30:56 < Cracki> nvm, scratch the "4.5v minimum" for reg, that's characteristic for vdd=5v, but nothing says vdd minimum
2020-05-23T18:32:31 < Cracki> random people say single ws2812 (not strings that actually draw something) may "work" with 3.3v supply
2020-05-23T18:33:09 < zyp> maybe I'll use something like a LP5569 instead
2020-05-23T18:34:10 < Cracki> ws2812 give absolute maximums, but the characteristics don't say for supply, only give *test conditions* of 4.5-5.5v supply
2020-05-23T18:35:46 < Cracki> driver, you wanna give it discrete leds then?
2020-05-23T18:36:29 < Cracki> oh you wanted small 2x2mm and I suggest 5x5mm stuff, my bad
2020-05-23T18:36:31 < zyp> I wanna have a few rgb indicators (like 3-4) and I don't wanna spend a ton of IO to run those
2020-05-23T18:36:57 < Cracki> do you need grayscale per channel, or is on/off good enough?
2020-05-23T18:37:24 < zyp> and I haven't decided yet on the power topology, so I'm not sure I'll have a 5V rail
2020-05-23T18:37:49 < zyp> dunno
2020-05-23T18:38:09 < zyp> fade patterns might be useful
2020-05-23T18:38:34 < zyp> otherwise I could go with one of those shift register style sink drivers
2020-05-23T18:40:24 < Cracki> much choice. fast shift registering is pwm too
2020-05-23T18:40:45 < zyp> hmm, the LP5569 looks a bit cute, can run patterns by itself

2020-05-23T19:25:53 < bitmask> actually it will help getting the 3.3v to the bottom

2020-05-23T20:34:48 < emeb> but yeah - the copy/paste issue in kicad was one of the main annoyances
2020-05-23T20:35:10 < emeb> since it used to work long ago, then they "improved" it so it didn't.
2020-05-23T20:35:11 < antto> wut do you mean?

2020-05-23T20:36:13 < emeb> only within the current project
2020-05-23T20:36:41 < antto> emeb okay, so you use a cheat then
2020-05-23T20:36:42 < zyp> really looking forward to length match this
2020-05-23T20:36:45 < emeb> so if you wanted to grab parts of another schematic to put in you'd have to add the pages of that schematic to the current project 
2020-05-23T20:37:19 < emeb> which is stupid and annoying.
2020-05-23T20:37:32 < antto> or just make your potentially reusable sh*t into hierarchical sheets to begin with
2020-05-23T20:37:40 < antto> then u just.. instantiate them
2020-05-23T20:38:07 < emeb> Or..... they could just make the software work correctly. Which it seems they have now done.
2020-05-23T20:38:12 < zyp> I'm using hierarchical sheets in this desing, it's kinda silly
2020-05-23T20:38:41 < antto> zyp wut eda is this?
2020-05-23T20:38:47 < zyp> altium
2020-05-23T20:39:11 < antto> it looks like kicad before openGL

2020-05-23T20:40:14 < zyp> eagle was less saturated :)
2020-05-23T20:40:57 < zyp> heh, pdf export from a hierarchical design ends up with a semi-random page order

2020-05-23T20:42:39 < zyp> am I doing hierarchical layout right?
2020-05-23T20:42:54 < zyp> top sheet ended up last
2020-05-23T20:42:55 < antto> aww
2020-05-23T20:43:33 < antto> zyp most craptium schematic PDFs i've seen so far never have electronics on the first page, only other subsheetz
2020-05-23T20:44:54 < antto> otherwise it looks typical
2020-05-23T20:44:55 < zyp> I don't usually bother, but it makes dealing with harnesses easier
2020-05-23T20:45:01 < antto> i have no idea wtf's going on
2020-05-23T20:45:06 < antto> are those thing "buses" ?
2020-05-23T20:45:28 < zyp> no, harnesses
2020-05-23T20:45:33 < antto> dafuq is that
2020-05-23T20:45:55 < zyp> a bus is an array of identical signals, a harness is a collection of different signals
2020-05-23T20:45:56 < antto> i've seen schematics.. i don't understand wtf's going on with these craptium ones

2020-05-23T22:00:44 < zyp> well, it's not done either
2020-05-23T22:01:46 < zyp> but yeah, I'm still not a super fan of the hierarchical style, I'm just trying it out
2020-05-23T22:02:36 < Thorn> I simply set net labels to global
2020-05-23T22:03:57 < englishman> zyp: you assign page numbers in some window, under annotate iirc
2020-05-23T22:06:09 < jpa-> hierarchical style works for some schematics, but has anyone yet found a use for more than 2 hierarchy levels?
2020-05-23T22:08:27 < jadew> they're great for more complex stuff
2020-05-23T22:08:35 < jadew> personally I prefer to have everything in view
2020-05-23T22:08:46 < jadew> old school A1 schematics
2020-05-23T22:18:57 < Cracki> it's all digital anyway, why organize it in fixed size sheets
2020-05-23T22:19:00 < zyp> jpa-, two as in top and other shit?
2020-05-23T22:19:09 < zyp> if so, I've got three levels in this
2020-05-23T22:19:24 < jadew> Cracki, it's a figure of speech
2020-05-23T22:19:35 < jadew> because A1 is a huge ass sheet of paper
2020-05-23T22:19:49 < Cracki> same with files of source code. there's no reason to organize it in files when you already have logical order like "class" and "module", where a class can span files, or a file can contain multiple classes, or a module spans multiple files
2020-05-23T22:20:01 < zyp> actually, I have four levels in this
2020-05-23T22:20:24 < zyp> top has overall layout like fpga/ram/etc…
2020-05-23T22:20:37 < zyp> fpga has power, memory, serdes, etc
2020-05-23T22:20:59 < zyp> and all the memory IO doesn't fit into one sheet comfortably either, so that one got two subsheets
2020-05-23T22:21:11 < Cracki> hierarchy makes sense, but maybe some kind of mindmap would represent things better _sometimes_
2020-05-23T22:21:50 < Cracki> you're not just arranging the implementation (schematic) but also presenting the architecture abstractly
2020-05-23T22:32:32 < zyp> englishman, ah, found it
2020-05-23T22:32:36 < zyp> never touched that feature before

2020-05-23T22:35:00 < zyp> a lot easier to navigate right away
2020-05-23T22:35:16 < zyp> (and yes, top sheet has some parts that haven't gotten their own sheet yet)

2020-05-24T00:23:30 < bitmask> not great but I got it all on one layer: https://i.imgur.com/FEiQioj.png
2020-05-24T00:24:23 < zyp> haha, nice
2020-05-24T00:26:36 < zyp> reminds me a of a layout I did in highschool; same concern as yours, I were gonna etch it myself and didn't wanna deal with vias
2020-05-24T00:27:07 < bitmask> :)
2020-05-24T00:27:13 < bitmask> and I only have 6 necessary holes
2020-05-24T00:27:20 < bitmask> that arent size critical
2020-05-24T00:27:25 < bitmask> for the trim pots
2020-05-24T00:27:35 < zyp> but I did it as a two layer design, got a pth opamp, pth connector and smt parts on both sides
2020-05-24T00:27:43 < bitmask> the st-link header doesnt NEED holes
2020-05-24T00:28:04 < zyp> the two sides of the board were only connected through the opamp
2020-05-24T00:28:23 < zyp> the connector had a shroud so I could only solder it from the bottom
2020-05-24T00:28:44 < zyp> I might still have the design, hang on
2020-05-24T00:28:59 < bitmask> yea I considered making the bottom of the board a ground plane which woulda cleaned things up a bit, then just connected it through some pth parts but decided to just do it this way
2020-05-24T00:29:33 < zyp> IIRC my board had pth trim pots
2020-05-24T00:29:44 < bitmask> its really only the gnd trace going from the regulator down to the bottom left and zig zagging that really bothers me
2020-05-24T00:30:29 < zyp> s/pth/smt/
2020-05-24T00:31:08 < bitmask> i wanted small pots that didnt require a screwdriver, these were the only ones I found: https://www.amazon.com/MCIGICM-Breadboard-Trim-Potentiometer-Arduino/dp/B07S69443J/
2020-05-24T00:37:03 < zyp> hmm, don't know where I've got those, if I still got them anywhere
2020-05-24T00:39:39 < zyp> time to figure out other stuff
2020-05-24T00:40:26 < zyp> I need to figure out a sane way to name serdes lanes wrt. direction
2020-05-24T00:42:44 < qyx> btw whats your current pcie pinout?
2020-05-24T00:44:18 < zyp> plain pcie but probably repurposing A5-8 for a USB pair and a CAN pair
2020-05-24T00:45:12 < zyp> I mean, I'm designing stuff that might be capable of talking actual pcie, so it makes sense to be able to plug it into a conventional slot as well
2020-05-24T00:45:31 < Thorn> I found a way to get cheap zynq: search for "xilinx processor for antminer control board" in Russian lol
2020-05-24T00:45:42 < zyp> haha, nice
2020-05-24T00:46:02 < zyp> did I mention the Artix-7 board I've got on the way?
2020-05-24T00:46:47 < zyp> I ordered one of the same ones that's mentioned in this tweet: https://twitter.com/enjoy_digital/status/1257985111469015040
2020-05-24T00:46:55 < Thorn> local Louis Rossmanns don't know what they're dealing with but do seem to have a source (most likely from China)
2020-05-24T00:47:24 < zyp> how much are the boards you've finding?
2020-05-24T00:47:32 < zyp> and what IO do they have?
2020-05-24T00:47:52 < Thorn> these ones seem to be obsolete https://mskminer.com/mskminer/shop_4/2/1/5/item_215/item_215.jpg
2020-05-24T00:48:04 < Thorn> so they must be real cheap
2020-05-24T00:48:23 < Thorn> talking to someone who seems to know the market rn
2020-05-24T00:49:45 < zyp> so anyway, how do I name serdes nets?
2020-05-24T00:50:06 < zyp> I'll have 12 tx/rx pairs on the board in total, in three sets of four
2020-05-24T00:50:31 < Thorn> not sure if the sources might dry up in a month or not when new EAR regulations come into effect
2020-05-24T00:50:41 < zyp> four from fpga to crosspoint switch, four from crosspoint switch to two usb-c sockets and four from crosspoint switch to backplane
2020-05-24T00:51:43 < zyp> if I only had the fpga and connectors on the board, the obvious answer would be naming everything after the direction they've got on the fpga
2020-05-24T00:52:04 < zyp> but when I got the switch in between, that gets kinda annoying
2020-05-24T00:55:14 < zyp> it's the same old problem that uarts also have
2020-05-24T00:57:26 < zyp> since the switch connects to everything, I could name everything by the direction on the switch end
2020-05-24T00:57:42 < Thorn> zyp I follow the path laid by USB-IF and use host-centric names, so RX sends data to the host, TX from the host
2020-05-24T00:58:31 < zyp> USB3 doesn't do that, AFAIK
2020-05-24T00:58:58 < zyp> AFAIK, TX on each socket is TX, cables cross TX to RX
2020-05-24T00:59:32 < zyp> but yeah
2020-05-24T01:00:25 < zyp> I figure I've got two choices; name everything after the switch for consistency or name everything after the opposite end and then put in a note in the switch schematic explaining why some lanes connects TX to TX and some connects TX to RX
2020-05-24T01:00:54 < zyp> and I'm leaning towards the latter
2020-05-24T01:01:22 < zyp> the thing is, I don't strictly have a host and a device, this stuff might be all symmetric

2020-05-24T01:19:02 < Cracki> for graphs of nodes 1,2,3... , I label the edges with their nodes, smaller number first ¯\_(ツ)_/¯
2020-05-24T01:19:34 < Cracki> which side takes tx-to-rx? the switch side?
2020-05-24T01:20:49 < zyp> well, one of them :)
2020-05-24T01:21:12 < Cracki> spi-like maybe, switch-X and X-switch
2020-05-24T01:21:25 < zyp> meh
2020-05-24T01:21:43 < Cracki> abbreviate to taste
2020-05-24T01:23:04 < zyp> I made a harness with RX/TX_P/N, and another harness for a quad of those, so I figure direction can be named on the outer harness or something if necessary
2020-05-24T01:23:40 < zyp> https://bin.jvnv.net/file/D5CMs.png <- next fun part is the fact that the serdes balls are on the side facing the sodimm
2020-05-24T01:24:05 < Cracki> fc/cs for Fpga-Cwitch, cs/sc for Crosspoint-Sockets, cb/bc for Crosspoint-Backplane?
2020-05-24T01:24:15 < Cracki> *Crosspoint
2020-05-24T01:24:41 < Cracki> uhhh rotate your owl
2020-05-24T01:24:56 < zyp> nah
2020-05-24T01:25:09 < zyp> I'm gonna use the other side IO as well
2020-05-24T01:25:30 < Cracki> right, there's no right way out of this
2020-05-24T01:26:00 < zyp> I figure it's easier to route around the serdes lanes than all the other signals I'd want to stuff in somewhere
2020-05-24T01:27:13 < zyp> and either way I want to have the same via count in each memory lane, and the leftmost one is the only one I can manage routing all in one layer
2020-05-24T01:27:37 < zyp> so I'm just gonna drop all the stuff on the right side to the bottom layer

2020-05-24T15:39:05 < zyp> boddax, 0x08000004 contains a pointer to the entry point
2020-05-24T15:39:45 < zyp> flash starts at 0x08000000, vector table is at start of flash and reset vector is the second entry in the table

2020-05-24T15:44:21 < azonenberg> way back when i was an undergraduate me and my roommate wrote a kernel for it

2020-05-24T15:44:28 < zyp> with the fun branch delay slots and all
2020-05-24T15:45:06 < azonenberg> the cpu i designed for my thesis was mips based because riscv either didnt exist or wasnt big yet. Do you know how much of a pain delay slots are on a hyperthreaded superscalar architecture?
2020-05-24T15:45:27 < azonenberg> i actually compiled all of my code with -fno-delayed-branch and then the cpu just assumed that the delay slot was a nop
2020-05-24T15:45:31 < azonenberg> found a gcc bug in the process :p

2020-05-24T19:21:21 < Thorn> how would you design a GATT service to manage files on a device (upload, list, rename, delete)?
2020-05-24T19:26:37 < jpa-> Thorn: how large files? is it reasonable to transfer them in one go (i.e. a few kilobytes at most)?
2020-05-24T19:26:54 < Thorn> nope,e could be multiple MBs
2020-05-24T19:31:28 < jpa-> for commands (move/delete) i'd probably just have a write-only characteristic that you write the name or pair of names to
2020-05-24T19:31:39 < catphish> how does an sflow collector work?
2020-05-24T19:32:04 < catphish> does it maintain its own flows internally?
2020-05-24T19:32:11 < jpa-> for upload, with such large files, i'd probably have a characteristic for a filename, block index and block data; and then a separate characteristic to request checksum of the whole file contents
2020-05-24T19:32:45 < catphish> i've been using netflow where every report is just stored, but that doesn't necessarily make sense for sflow
2020-05-24T19:36:23 < Thorn> jpa- there's also a big difference in speed between normal write and write without response, so I'm thinking about something zmodem like with a sliding window for file transfers
2020-05-24T19:37:48 < jpa-> i'd go write without response and check cheksum later; but might be useful to have a blockwise checksum also, would make it faster to resume failed uploads
2020-05-24T19:39:31 < qyx> Steffanx: D1 has wrong footprint

2020-05-24T23:56:31 < Steffanx> Ah you didnt mess with that
2020-05-24T23:57:05 < catphish> i'm just replacing the controller board
2020-05-24T23:57:32 < catphish> my biggest worry is that is crashed with the door locked!
2020-05-24T23:57:39 < catphish> *crashes
2020-05-24T23:58:05 < catphish> might look at adding a watchdog / OOB way to unlock
2020-05-24T23:58:32 < Steffanx> Hehe.
2020-05-24T23:59:09 < catphish> if that happens, the only way to get in is kill the power and wait 24 hours until the battery runs out :)
2020-05-24T23:59:22 < qyx> brea the glass
2020-05-24T23:59:36 < catphish> the glass is inside, that's fine if you're inside
--- Day changed Mon May 25 2020
2020-05-25T00:00:00 < catphish> but if you're outside you have more of a problem
2020-05-25T00:03:21 < Steffanx> You did not activate the stm32s watchdog yet?

2020-05-25T01:00:32 < zyp> I'm gonna clean it up and length match shit, but first I'm planning to synthesize a design for it as a sanity check of the pinout

2020-05-25T01:35:51 < zyp> sure, but why is Q3 freezing?

2020-05-25T12:34:53 < PaulFertser> What common do patents, design patents, trademarks and artwork have? Just that they're all not physical objects. Everything else is different. The laws concerning those are all distinct too (and that's no wonder). And none of the mentioned is regulated the same way as physical objects belonging to somebody.
2020-05-25T12:36:36 < PaulFertser> Ah, and I've forgotten to mention "trade secrets" which are yet another different thing.
2020-05-25T12:37:45 < PaulFertser> Using an umbrella term for all of those means either one of the two things: 1. You're totally confused; 2. You're trying to confuse the others.

2020-05-25T13:48:25 < mawk> you can use them sure
2020-05-25T13:48:39 < mawk> if you don't use I²C on them
2020-05-25T13:48:44 < mawk> or can
2020-05-25T13:48:54 < Mangy_Dog> not on those pins no
2020-05-25T13:49:22 < Mangy_Dog> i2c on 6 and 7 though
2020-05-25T13:52:06 < mawk> move i2c to pb10/pb11 then maybe

2020-05-25T13:52:18 < qyx> wat

2020-05-25T14:07:36 < dongs> i recommend jlink
2020-05-25T14:07:52 < Mangy_Dog> sure its prolly the clone stlink
2020-05-25T14:07:55 < dongs> F103 is M3, so you can actualyl use ITM_sendChar
2020-05-25T14:08:05 < dongs> and printf to the shit effortlessly
2020-05-25T14:08:37 < Mangy_Dog> i dont think printf works in rogers core
2020-05-25T14:08:41 < Mangy_Dog> which is what im using on this projkect
2020-05-25T14:10:20 < Mangy_Dog> its ok ive just freed up serial 1 pins

2020-05-25T15:53:55 < Mangy_Dog> gah
2020-05-25T15:54:00 < Mangy_Dog> whats going on with jlc
2020-05-25T15:54:09 < Mangy_Dog> im getting the engineering fee added
2020-05-25T15:54:16 < Mangy_Dog> and a 5 quid board charge
2020-05-25T15:54:23 < Mangy_Dog> even though im bellow the 10x10cm :/
2020-05-25T15:54:37 < dongs> is this kikecad?
2020-05-25T15:54:44 < dongs> they've been busy stealing from altium
2020-05-25T15:54:46 < zyp> maybe they have wisened to your trick
2020-05-25T15:54:59 < Mangy_Dog> not on an automated system
2020-05-25T15:55:12 < Mangy_Dog> this isnt post inspection
2020-05-25T15:55:15 < Mangy_Dog> its the uploader
2020-05-25T15:55:27 < dongs> why the fuck do you have such tiny silkscreen
2020-05-25T15:55:31 < dongs> chinkpcb isnt gonna rendedr it
2020-05-25T15:55:36 < dongs> its gonna be a fucking unreadable mess
2020-05-25T15:55:42 < Mangy_Dog> because i cant go larger
2020-05-25T15:55:49 < dongs> and who teh fuck pots part names and capacitor values on silkscreen
2020-05-25T15:55:52 < Mangy_Dog> and the silks rendered fine before at this size
2020-05-25T15:55:54 < dongs> get rid of that shit completely
2020-05-25T15:56:05 < dongs> im talking about on PCBN
2020-05-25T15:56:07 < dongs> PCB
2020-05-25T15:56:11 < dongs> not on fuckingf csreen
2020-05-25T15:56:13 < Mangy_Dog> because its easyer for me toi pick and place it ratehr than refering to a reference

2020-05-25T15:56:53 < Mangy_Dog> yes but its easier for me to just... SEE where im putting it
2020-05-25T15:56:58 < Mangy_Dog> rather than looking at a bom list
2020-05-25T15:57:00 < Mangy_Dog> over and over
2020-05-25T15:57:05 < Mangy_Dog> and over and over and over and over 
2020-05-25T15:57:09 < Mangy_Dog> and double checking i read it right
2020-05-25T15:57:14 < dongs> you aint gonna see shit with that size
2020-05-25T15:57:16 < dongs> i just told you
2020-05-25T15:57:21 < Mangy_Dog> well i am
2020-05-25T15:57:23 < dongs> chinkpcb is gonna turn that silk into unreadable mess
2020-05-25T15:57:25 < Mangy_Dog> as ive done it at this size before

2020-05-25T15:59:33 < jadew> lol, you have values printed on the PCB
2020-05-25T15:59:35 < jadew> way to get cloned
2020-05-25T15:59:36 < Mangy_Dog> who cares its an image link
2020-05-25T15:59:42 < Mangy_Dog> who cares
2020-05-25T15:59:50 < zyp> dongs, speaking of pcbs, how much can you do 6L protos for?
2020-05-25T15:59:56 < Mangy_Dog> no ones going to bother cloning this
2020-05-25T16:00:00 < dongs> zyp, way more than 4L
2020-05-25T16:00:08 < dongs> looking at 400$+ minimum so just go to china
2020-05-25T16:00:15 < zyp> figured
2020-05-25T16:00:18 < zyp> how about production?
2020-05-25T16:00:32 < dongs> slightly more than 4L , comparable to ll-del thing
2020-05-25T16:00:40 < zyp> nice
2020-05-25T16:01:40 < zyp> jlcpcb wants $130 for this
2020-05-25T16:01:42 < dongs> i did some impedance matched 4L next day turn, it was around 900 for 20 boards
2020-05-25T16:02:02 < dongs> board size around 50x60 or so if i remember
2020-05-25T16:02:04 < zyp> 6L, 100x100mm, 0.2/0.4 vias, ENIG

2020-05-25T16:02:31 < zyp> haha
2020-05-25T16:02:52 < zyp> based on photos I've seen of jlcpcb stuff, they are better than average china stuff

2020-05-25T16:06:46 < dongs> you need to lurk moar
2020-05-25T16:07:46 < jadew> china is not a race

2020-05-25T16:48:03 < aandrew> Mangy_Dog: yes, I know it's a level shift but the body diode is conducting from 5V to 3.3V

2020-05-25T16:48:39 < Mangy_Dog> ohh
2020-05-25T16:48:44 < aandrew> strata: how in the fuck did you manage to snap the cast casing on that alternator
2020-05-25T16:49:07 < Mangy_Dog> admitidly i copied that bit of circuit off there own breakout for that chip
2020-05-25T16:50:08 < strata> aandrew, i suspect it was the result of the tensioner siezing up and somehow causing the belt to yank on the alternator pully hard enough to rip it before snapping and getting gobbled up by the other pullies and starting a small rubber fire
2020-05-25T16:50:13 < aandrew> with a good enough 3.3V regulator it'll work just fine, just dissipate a lot of current until either the regulator shuts down on overtemp or the fet dies due to I2T
2020-05-25T16:50:57 < Mangy_Dog> are you talking to me?
2020-05-25T16:50:59 < Mangy_Dog> or strata

2020-05-25T16:51:27 < aandrew> strata: that's pretty incredible
2020-05-25T16:51:41 < Mangy_Dog> mind if we PM to keep track?
2020-05-25T16:51:41 < aandrew> or just a real shit casting, which is also entirely plausible
2020-05-25T16:51:59 < aandrew> Mangy_Dog: nothing to discuss. flip S/D on that one FET and you're good. the one above it is correct

2020-05-25T17:01:17 < aandrew> yeah. those are correctly oriented
2020-05-25T17:01:25 < aandrew> so I ahve a question
2020-05-25T17:01:32 < Mangy_Dog> ok
2020-05-25T17:01:39 < aandrew> I saw kicad can actually support non-eye-bleeding colour schemes and fonts and antialiasing
2020-05-25T17:01:47 < Mangy_Dog> lol
2020-05-25T17:01:55 < Mangy_Dog> i have no idea how to make it easy on the eye
2020-05-25T17:02:14 < aandrew> why the FUCK do you use it with that default config? do you pine for the old OrCAD SDT/PCB386+ days (which even THEN had better fonts and colours and rendering)
2020-05-25T17:02:18 < Mangy_Dog> oh wait no found options to change colours
2020-05-25T17:02:31 < specing> KiCAD suffers from wxWidgets
2020-05-25T17:02:36 < benishor> Mangy_Dog:  a) use a later version, b) pour some antialias on it, c) change colors
2020-05-25T17:02:45 < aandrew> and everyone seems to not give a flying fuck about text orientation or text bleeding into each other
2020-05-25T17:03:02 < benishor> wxwidgets is only a decorator 
2020-05-25T17:03:03 < aandrew> it reminds me of Make:r Eagle schematics
2020-05-25T17:03:12 < Laurenceb> lol
2020-05-25T17:03:12 < aandrew> you *can* have good Eagle schematics but nobody does
2020-05-25T17:03:14 < Mangy_Dog> well theres no AA im on latest version and meh 
2020-05-25T17:03:20 < aandrew> looks ... unprofessional
2020-05-25T17:03:23 < Mangy_Dog> not saying the colour sceheme is great but im not fussed
2020-05-25T17:03:25 < Laurenceb> who cares about schematics
2020-05-25T17:03:47 < aandrew> like look at how the text "R21" and "R35" is spilling on to the Q5/Q6 symbols
2020-05-25T17:04:04 < aandrew> why is the designator text 500 miles away from the actual resistor body?

2020-05-25T17:04:33 < Mangy_Dog> because ive not bothered to move it :p and yeah theres no simple auto way for kicad to do that
2020-05-25T17:04:37 < aandrew> I know it's your schematic and you can do it any way you want; I'm not actually mad at you or anything (not like it'd matter) but why? it's sloppy
2020-05-25T17:05:14 < Mangy_Dog> ahh thanks ben
2020-05-25T17:05:32 < Mangy_Dog> well it wasnt intended for public consumption really
2020-05-25T17:05:37 < Mangy_Dog> if it was id spend more time tidying it up
2020-05-25T17:05:47 < Mangy_Dog> its mostly just functional and for me to work with
2020-05-25T17:06:05 < benishor> here's how my shit looks https://imgur.com/a/Yoke6au
2020-05-25T17:06:46 < Mangy_Dog> well thats easy on the eye
2020-05-25T17:06:46 < Mangy_Dog> @[
2020-05-25T17:06:46 < benishor> kicad schematics can look good enough (for me, at least)
2020-05-25T17:06:48 < Mangy_Dog> :p
2020-05-25T17:07:35 < benishor> see the antialiasing there?
2020-05-25T17:07:56 < benishor> it's 3 clicks away or so, no reason not to use it
2020-05-25T17:07:56 < Mangy_Dog> yeah trying different options out now
2020-05-25T17:09:10 < aandrew> definitely better benishor, still the "within the instant-death nuclear blast zone" colour scheme
2020-05-25T17:09:37 < aandrew> benishor definitely has nice refdes/value placement
2020-05-25T17:09:48 < benishor> aandrew: yeah, I'm trying to get the standard look better
2020-05-25T17:10:01 < aandrew> way more pro looking output
2020-05-25T17:10:02 < benishor> simply because it's a hassle trying to change the colour scheme in kicad for now
2020-05-25T17:10:21 < benishor> luckily I'm just a hobbyist so I have the time to tweak shit around
2020-05-25T17:10:42 < aandrew> it's too bad the default symbols for off-page net and supply/gnd touch, but even Altium has that issue
2020-05-25T17:11:06 < aandrew> heh Riz and Ciz :-)
2020-05-25T17:11:11 < Mangy_Dog> aandrew whats your colour scheme like then?
2020-05-25T17:11:37 < aandrew> default altium, and was default eagle before that
2020-05-25T17:12:46 < Mangy_Dog> can you show a pic im tryign to google
2020-05-25T17:14:28 < Mangy_Dog> https://www.sfcircuits.com/userfiles/image/altium-monitor-schdoc-1.jpg
2020-05-25T17:14:30 < Mangy_Dog> like that?
2020-05-25T17:14:52 < aandrew> something like https://imgur.com/a/IyemiVw
2020-05-25T17:15:05 < aandrew> wow that's ancient altium you linked there Mangy_Dog 
2020-05-25T17:15:09 < Mangy_Dog> thats a little better than the other screen grab
2020-05-25T17:15:22 < Mangy_Dog> like i say just some random googe image
2020-05-25T17:15:33 < Mangy_Dog> im not overly keen on blue though
2020-05-25T17:15:35 < Mangy_Dog> blue glares
2020-05-25T17:15:43 < Mangy_Dog> as we have less blue photoreseptors in the eye
2020-05-25T17:16:02 < Mangy_Dog> as vomit inducing as geren on red might be for you... it actually means its easyer for you to see
2020-05-25T17:16:11 < benishor> looking at the two, I like mine better
2020-05-25T17:16:20 < benishor> sorry, altium
2020-05-25T17:16:36 < Mangy_Dog> heh but i could do with tweaking it to be less........ saturated
2020-05-25T17:16:41 < Mangy_Dog> maybe a little darker
2020-05-25T17:17:13 < benishor> you can do that by tweaking the colours, but I learned the hard way that any customization you do on software is an extra thing to maintain further on
2020-05-25T17:17:32 < zyp> yeah, fuck that
2020-05-25T17:17:36 < benishor> and that gets hard whenever you reinstall systems or have several systems on several platforms in parallel
2020-05-25T17:17:46 < Mangy_Dog> yeah
2020-05-25T17:17:50 < benishor> so fuck that, I'm going with standards
2020-05-25T17:17:55 < zyp> schematic color schemes are bikeshedding
2020-05-25T17:17:57 < benishor> except if there's a one click tweak
2020-05-25T17:18:35 < benishor> I'm more interested in things looking good on screen from antialiasing pov; and then they should look good when printed, ofc
2020-05-25T17:18:44 < benishor> kicad for instance has some fucked up components proportions IMO
2020-05-25T17:19:04 < zyp> components as in premade symbols?
2020-05-25T17:19:07 < benishor> so in my schematics I use US resistors/capacitors with "small" designators
2020-05-25T17:19:13 < benishor> yes, premade symbols
2020-05-25T17:19:20 < zyp> fuck those
2020-05-25T17:19:40 < benishor> I want the things to look good and get a feeling of unity
2020-05-25T17:20:30 < zyp> just roll your own symbols
2020-05-25T17:23:51 < aandrew> ok that's new
2020-05-25T17:24:00 < aandrew> one of my blades is running ESXi
2020-05-25T17:24:14 < aandrew> I can't hit the ESXi server, but I can talk to all the VMs it's running
2020-05-25T17:48:30 < karlp> in related networking fun, replaced some failed 4g modems recently. new one has gone offline again.
2020-05-25T17:48:52 < karlp> went out to visit.  turns out if it loses power, and the power comes back on again, it doesn't turn on again, you have to manualyl push a power button to restart it...
2020-05-25T17:49:03 < karlp> thanks for nothing...
2020-05-25T17:55:25 < qyx> 4g modem with push button?
2020-05-25T17:55:51 < karlp> it has two buttons, a "power" button, and a "menu" button, that scrolls a few things on it's display.
2020-05-25T17:56:30 < qyx> what model?
2020-05-25T17:56:33 < karlp> this shit: https://www.zyxel.com/products_services/LTE-Portable-Router-WAH7706/
2020-05-25T18:19:17 < zyp> huh, just had a power outage, seems to have killed the power supply for my mikrotik switch
2020-05-25T18:20:45 < zyp> not sure if the problem is in the supply or the switch, but the switch works when switching from barrel jack to PoE input
2020-05-25T18:23:19 < karlp> fucking power
2020-05-25T18:24:50 < qyx> we had power outage too today
2020-05-25T18:26:05 < zyp> I should probably invest in some new PSUs some time
2020-05-25T18:26:16 < zyp> UPSes*
2020-05-25T18:27:08 < zyp> the one for my server under the stairs died last year, and I haven't bothered replacing it because this is the first outage since
2020-05-25T18:27:57 < zyp> and the one for my workstation is probably getting bad too, because it didn't run many minutes
2020-05-25T18:30:50 < zyp> the extra fun part is that I'm running altium in a VM that's stored on a network share from the server downstairs
2020-05-25T18:31:40 < strata> aandrew, it is the OEM alternator - while great - is still OEM and 15 years old
2020-05-25T18:32:05 < strata> we've also had insane oscillation due to grand solar minimum here
2020-05-25T18:32:29 < strata> so the alternator has gone from sub-zero to 100F+ in the last few years

2020-05-25T19:09:17 < Laurenceb> I improved the sim code and am pretty satisfied with it now
2020-05-25T19:09:54 < Laurenceb> so unheated polytunnel is pretty dreadful, even when double glazed
2020-05-25T19:11:43 < Laurenceb> but just adding a load of 220L barrels solves most of the issues
2020-05-25T19:13:27 < Laurenceb> adding barrels takes growing season from ~4.5months to ~9months
2020-05-25T19:13:56 < Laurenceb> adding solar water heaters only expands it to ~10.5 or poss 11months
2020-05-25T19:14:46 < Laurenceb> the sim barrels were standard 220L ones painted matt black in that plot

2020-05-25T19:30:01 < Laurenceb> at least they are honest about their plans, unlike englishman
2020-05-25T19:30:08 < karlp> barrels take up space of course...
2020-05-25T19:30:35 < karlp> won't the barrels also keep things cold in themorning longer?
2020-05-25T19:30:40 < karlp> it's just buffering right?
2020-05-25T19:30:46 < Laurenceb> yeah
2020-05-25T19:30:56 < Laurenceb> they only take up ~14% of floor area

2020-05-25T19:32:12 < BrainDamage> barrels sound quite annoying when moving around
2020-05-25T19:32:13  * karlp doesn't get it then, buffeirng with more thermal mass should just mean you get lower highs and higher lows, I don't really get how you're extending the season like that?
2020-05-25T19:32:33 < karlp> I guess the season is limited by how low the low gets?
2020-05-25T19:32:42 < karlp> not realyl by how high the high goes?
2020-05-25T19:32:44 < Laurenceb> karlp: plants really dont like getting frozen at night
2020-05-25T19:32:46 < Laurenceb> yeah
2020-05-25T19:32:56 < BrainDamage> yes, it's to limit the low end temps
2020-05-25T19:33:08 < karlp> ok, and lower highs doesn't matter, fair enough.
2020-05-25T19:33:24 < karlp> or, doens't matter nearly as mcuh I guess :)
2020-05-25T19:33:51 < BrainDamage> well, it's good for ... human comfort
2020-05-25T19:34:11 < Laurenceb> well from the graph the polytunnel is already hitting max temp by March
2020-05-25T19:34:14 < BrainDamage> constant temp all year round is good, plants care more about sunlight than temp
2020-05-25T19:34:22 < Laurenceb> so without a butter its wasting energy
2020-05-25T19:34:30 < Laurenceb> *buffer

2020-05-25T19:48:26 < Laurenceb> like 50cm or so
2020-05-25T19:49:00 < englishman> big flat water tanks placed inside the greenhouse are more efficient
2020-05-25T19:49:01 < Laurenceb> and then it might not be thermally conductive enough
2020-05-25T19:49:28 < Laurenceb> yeah I guess, but they have to be made, not just grabbed in bulk

2020-05-25T23:22:15 < PaulFertser> After more than 10 years of using my professional bicycle pump I finally realised how to do it properly. All these years I was using it on push bikes, cars, motor bikes in a rather suboptimal way. What a twist.

2020-05-25T23:23:35 < PaulFertser> And it's not like I'm dumb about mechanics and related stuff...
2020-05-25T23:24:13 < PaulFertser> Steffanx: it has a head which you rotate 180 degrees. In one position it's presta valve, in another it's schrader.
2020-05-25T23:24:49 < Steffanx> Oh, haha.
2020-05-25T23:24:52 < PaulFertser> Steffanx: all these years I was doing it like this: rotate to the target position, unscrew the cap a bit, put it on, screw the cap tight and start pumping, once it's ready unscrew it a bit to remove.
2020-05-25T23:25:38 < kakimir> foot pump ftw
2020-05-25T23:25:58 < kakimir> I concider baton types emergency pumps
2020-05-25T23:26:18 < kakimir> I don't have foot pump
2020-05-25T23:26:31 < kakimir> but I have tried it and it was so satisfying and effective!
2020-05-25T23:26:50 < PaulFertser> Steffanx: and just now I had a closer look inside the head with the cap removed and saw that it's actually doing a fair bit of motion inside when I rotate the head. And then I saw the labels which basically should have been told me that the head should be in the 90 degrees position, then you put it on, then rotate 90 degrees to the desired valve type. Rotate back when finished.
2020-05-25T23:27:17 < Steffanx> I need a pic i guess :P
2020-05-25T23:27:21 < PaulFertser> kakimir: can your foot pump do 900+ kPa?
2020-05-25T23:27:50 < kakimir> can your baton?

2020-05-25T23:28:23 < kakimir> ah
2020-05-25T23:28:27 < kakimir> that is even better
2020-05-25T23:28:37 < kakimir> hey.. I think I bought one
2020-05-25T23:29:24 < PaulFertser> I think it's really handy. I could pump 200 kPa into my car wheels in no time with it.
2020-05-25T23:29:46 < kakimir> yes
2020-05-25T23:30:09 < Steffanx> kakimir likes to train his legs
2020-05-25T23:30:16 < kakimir> yes
2020-05-25T23:30:27 < kakimir> just legs
2020-05-25T23:30:29 < kakimir> make them big
2020-05-25T23:30:38 < kakimir> keep torso small
2020-05-25T23:31:05 < Steffanx> No more waffles for you then
2020-05-25T23:31:50 < PaulFertser> Steffanx: something like this https://bikepakmart.com/wp-content/uploads/2020/02/Hose_Head.jpg but on mine it's rotating via another axle, coaxial to the hose.
2020-05-25T23:32:54 < PaulFertser> Probably 15 years. Using it wrong, lol. idk how to explain it, I'm not _that_ stupid...
2020-05-25T23:34:39 < kakimir> every cyclist knows what I mean about make legs big keep torso small
2020-05-25T23:35:03 < Steffanx> But you need a six pack for the girls kakimir
2020-05-25T23:35:20 < kakimir> yes but if you are true cyclist no
2020-05-25T23:35:33 < kakimir> no muscles above waist
2020-05-25T23:35:45 < PaulFertser> Steffanx: lots of cycling actually makes plenty of muscles strong, not just legs.

2020-05-25T23:43:32 < PaulFertser> That's what I'm used to doing. Never thought I actually need to rotate the head instead with this pump.
2020-05-25T23:43:43 < Steffanx> But idk havent used it in a long timd
2020-05-25T23:44:01 < PaulFertser> How do you pump?
2020-05-25T23:45:08 < Steffanx> I dont? :P
2020-05-25T23:46:19 < PaulFertser> What if you need to change or repair a tube in your push bike?
2020-05-25T23:46:26 < Steffanx> Havent used my race bicycle in a while. And my other two got stolen a while back
2020-05-25T23:47:26 < PaulFertser> :(
2020-05-25T23:47:33 < PaulFertser> Poor Steffanx 
2020-05-25T23:47:49 < PaulFertser> I had my old MTB stolen.
2020-05-25T23:47:51 < Steffanx> Hah. I have a car now. I got lazy
2020-05-25T23:49:34 < PaulFertser> But that was my own fault, I assumed that being close to the security guards is enough and didn't even use any security device at all. But it was December so about 17:00 it was already dark. And the security folks were on the second floor not seeing somebody silently walking away with my bike. Just the footsteps on the snow left.
2020-05-25T23:55:35 < PaulFertser> I had a car, it looked kinda like this: https://a.d-cd.net/f4fbc3u-960.jpg (same model and colour but 20+ years old). 
2020-05-25T23:56:14 < Steffanx> Awesome :)
2020-05-25T23:57:18 < kakimir> my neighbour had one
2020-05-25T23:57:34 < kakimir> he was 15 back then I think
2020-05-25T23:57:50 < kakimir> I know one dude that uses one as daily driver
2020-05-25T23:57:53 < PaulFertser> It was surprisingly reliable too, thanks to the Italian heritage.
2020-05-25T23:58:25 < kakimir> there is a small lada scene somewhere out there 
2020-05-25T23:58:45 < kakimir> people keeping those boxes running and they use them as daily drivers
2020-05-25T23:59:04 < qyx> a colleague of mine had Niva
2020-05-25T23:59:16 < qyx> (about 2 years ago)
2020-05-25T23:59:20 < kakimir> niva is pretty good offroader
2020-05-25T23:59:29 < kakimir> just get a model that had locks in diffs
2020-05-25T23:59:47 < kakimir> apparently some had locks and some didn't etc.
2020-05-25T23:59:48 < PaulFertser> kakimir: having full lock in front diff is risky, you know why?
--- Day changed Tue May 26 2020
2020-05-26T00:00:10 < kakimir> having full lock in mid diff is risky that I know
2020-05-26T00:00:12 < PaulFertser> kakimir: nope, all nivas had factory inter-axle diff lock and no axle diff locks at all.
2020-05-26T00:00:23 < kakimir> ah
2020-05-26T00:00:33 < kakimir> so there needs to be something done to that back diff then
2020-05-26T00:00:42 < PaulFertser> kakimir: no, mid diff lock is not risky. You just do not engage it during normal driving.
2020-05-26T00:00:51 < kakimir> but if you do
2020-05-26T00:01:19 < kakimir> it can and will lead eventually in unrecoverable 4wd slide
2020-05-26T00:01:45 < kakimir> unrecoverable meaning there is no driver input than can revert it
2020-05-26T00:02:43 < PaulFertser> kakimir: but talking about front lock, you see, with an open diff you get maximum 50 % of the engine torque per wheel. But if you lock the diff you get up to 100 % of torque on a single wheel. And if you do that and especially if you do it when it's steered far enough, you risk breaking the CV joint.

2020-05-26T00:03:06 < kakimir> ah
2020-05-26T00:03:23 < kakimir> and the steering wheel is something to struggle with
2020-05-26T00:03:39 < kakimir> I have never thought that
2020-05-26T00:03:46 -!- strata_ is now known as strata
2020-05-26T00:04:13 < PaulFertser> kakimir: so some kind of "LSD" is more suitable for the front axle.
2020-05-26T00:05:12 < kakimir> locks in front are unusual
2020-05-26T00:05:44 < kakimir> I don't know any car with any kind of front lock
2020-05-26T00:07:12 < PaulFertser> Funny fact regarding diff locks. UAZ never had an inter-axle diff, it's RWD part-time. So if you enable 4WD mode it's the same as having a locked mid diff. And on modern uaz patriot if your windscreen wiper fuse blows it engages 4WD immediately (because they're on the same fuse).
2020-05-26T00:09:31 < PaulFertser> In many cases https://en.wikipedia.org/wiki/Traction_control_system is enough to "imitate" the diff locks. "Braking action on slipping wheel(s) will cause power transfer to wheel axle(s) with traction due to the mechanical action within the differential."
2020-05-26T00:13:26 < kakimir> and when you need static grip you are f'd
2020-05-26T00:14:13 < qyx> PaulFertser: re: fuse :D

2020-05-26T13:51:06 < Thorn> hi Steffanx 
2020-05-26T13:54:38 < lomas_> I am working in STM32F070 (Nucleo 64 board) using atollic and pretty irritated with debugger issue, i.e. Failed at line:6 in "Target Software Startup Scripts". Please edit the debug configuration settings. The error is in this picture too : https://imgur.com/M2EUQPn. Looking for bit more explanation if possible. Thank you.
2020-05-26T13:56:02 < karlp> very pro
2020-05-26T13:57:06 < PaulFertser> lomas_: don't you have more messages in the bottom part of that Eclipse thing? The console
2020-05-26T13:57:18 < PaulFertser> I'm sure something is visible there.
2020-05-26T14:01:25 < lomas_> There is nothing while the IDE is in debug perspective, however this is the snapshot (https://imgur.com/undefined) after returning from debugging mode.
2020-05-26T14:02:04 < lomas_> PaulFertser, Did not see the log file as well. 
2020-05-26T14:07:41 < PaulFertser> lomas_: the last link is no good
2020-05-26T14:08:30 < lomas_> Just noticed, This is the link which was supposed to be pested: https://imgur.com/f3JmmgL
2020-05-26T14:08:33 < PaulFertser> lomas_: perspective doesn't affect contents of eclipse panes afaik

2020-05-26T14:10:24 < lomas_> I see.. Thank you :).
2020-05-26T14:11:26 < lomas_> I tried with STlink Utility and STM32Cube programmer, it was working fine.
2020-05-26T14:11:44 < lomas_> I mean it gets flashed, erasing the chip etc .. 
2020-05-26T14:12:32 < PaulFertser> idk about that strange gdb server, I'm using OpenOCD.
2020-05-26T14:16:31 < lomas_> PaulFertser, can I integrate OpenOCD with atollic ?
2020-05-26T14:17:00 < lomas_> In the mean time what is the difference on them ? Why you use that ?
2020-05-26T14:17:20 < PaulFertser> lomas_: I have no idea. Isn't attolic old thing anyway? Why do not you use their STSW IDE or whatever they call it nowada'ys.
2020-05-26T14:17:45 < PaulFertser> lomas_: I use OpenOCD because it's powerful, flexible and free software.

2020-05-26T14:51:44 < Mangy_Dog> Need a little advise and brainstorming... So building a little reflow oven. I need to come up with a simple but best solution for controlling the heating elements. In my mind i was thinking of having key temperatures set at key times, matching the reflow graphs. Then the software basically checks temp every second and devide the target temp along a linear curve and "if temp<lintarget heat=true 
2020-05-26T14:51:44 < Mangy_Dog> else heat=false"... It turn on the element. Now this is super simple and theres no PWM control to maintain a temp so the final temp will be a little wobbly for sure... Is there a better way to do it? Can these ceramic heating elements be PWM controlled? Though I dont know what the best maths for that would be...
2020-05-26T14:51:53 < Mangy_Dog> yay big paragraph paste :/
2020-05-26T14:51:54 < Mangy_Dog> sorry
2020-05-26T14:55:12 < jpa-> sure, you can do PWM control
2020-05-26T14:55:31 < jpa-> but, the important question is where is your temperature sensor and what is the lag from the heater to it
2020-05-26T14:56:13 < zyp> Mangy_Dog, what about a PID controller?
2020-05-26T14:57:40 < jpa-> hard part of DIY reflow ovens seems to be the balance between radiation vs. convection heating
2020-05-26T14:59:43 < jpa-> PID works, but it usually ends up just running the heater at 100% on the ramp-to-peak phase, which typically makes the elements glow red hot and most of the heating happens through radiation, at which point controlling it based on a temperature sensor is not very useful
2020-05-26T15:01:22 < zyp> true
2020-05-26T15:02:30 < Mangy_Dog> hmm
2020-05-26T15:02:51 < Mangy_Dog> oh btw that mp1 event is starting in an hour
2020-05-26T15:03:44 < jpa-> i'd recommend PID for getting the convective preheat temperature right, and then for the ramp & peak just have a preprogrammed duration of 100% heating
2020-05-26T15:04:19 < Mangy_Dog> i didnt want to have to get a special unit... just gonna use a old arduino mini i have
2020-05-26T15:04:29 < Mangy_Dog> whats the best way to program pid?
2020-05-26T15:04:33 < Cracki> pid is not a big deal. you can start with your scheme that's "bang-bang", and you'll see where its downsides are, and a PID controller naturally evolves from that
2020-05-26T15:04:50 < Mangy_Dog> hmm
2020-05-26T15:05:04 < Cracki> you'd want the arduino to read serial so you can tweak variables on the fly
2020-05-26T15:05:16 < Cracki> that's trivial, but useful
2020-05-26T15:06:06 < Cracki> it has readline, find the space, split the strings, do some comparisons (what variable is named) and string to int/float conversion, that's all
2020-05-26T15:06:19 < Mangy_Dog> nods
2020-05-26T15:07:46 < zyp> heh, it's faster to get stuff from china than from france now
2020-05-26T15:08:09 < Cracki> order a tear gas grenade, two seconds air mail
2020-05-26T15:08:29 < zyp> hah
2020-05-26T15:08:55 < Mangy_Dog> do ceramic elements like being pwmed?
2020-05-26T15:08:59 < Mangy_Dog> or will that likely kill them?
2020-05-26T15:09:13 < Mangy_Dog> liek turning a light bulb on and off a lot
2020-05-26T15:09:13 < zyp> why would that be a problem?
2020-05-26T15:09:26 < Mangy_Dog> tends to burn out the boils quickly
2020-05-26T15:09:28 < zyp> light bulbs have no issue being pwmed either
2020-05-26T15:10:32 < Mangy_Dog> well in that case what i might do then id "bangbang" as you called it but depending on the temp difference change the duty on the pwm 
2020-05-26T15:10:36 < jpa-> turning light bulb on and off with several seconds duration is a problem just because (incandescent) light bulbs have a high inrush current; same is somewhat true with heaters but to a lesser extent, and you could just PWM with a faster cycle
2020-05-26T15:10:38 < Mangy_Dog> might help maintain a better curve
2020-05-26T15:10:57 < jpa-> congrats, you have invented P controller
2020-05-26T15:11:14 < Mangy_Dog> that a bad thing or a good thing :p
2020-05-26T15:11:20 < jpa-> two more letters to go
2020-05-26T15:11:25 < Mangy_Dog> :D
2020-05-26T15:11:38 < Mangy_Dog> explain the other two parts :D
2020-05-26T15:11:42 < zyp> a bang bang controller is just a P controller with infinite gain
2020-05-26T15:12:30 < jpa-> next up is I: if you are PWM:ing at 50% and the temperature is staying below your target, maybe you should slowly increase the duty a bit
2020-05-26T15:12:31 < Cracki> the only things that don't like pwm are actual relays because they have mechanical parts. that's where the fear of PWM stems from.
2020-05-26T15:12:55 < Mangy_Dog> im srring
2020-05-26T15:13:00 < jpa-> and finally D: if you are PWM:ing at 50% and the temperature is rising really fast, maybe you should reduce the duty a bit to avoid it rising over the target
2020-05-26T15:13:27 < Mangy_Dog> ok
2020-05-26T15:13:44 < zyp> IME it's pretty fucking hard to get the D term to be useful
2020-05-26T15:13:49 < Mangy_Dog> so i need to keep a history of several temp readings to see if the ramp up is too high or too low
2020-05-26T15:13:50 < Cracki> "staying below your target" means you integrate that error, and add it (with a factor) to your "command" (output)
2020-05-26T15:14:18 < Cracki> no history at all, except some "state" for integrating
2020-05-26T15:14:31 < jpa-> zyp: sometimes yeah, though in some systems it is impossible to make them stable without a D term
2020-05-26T15:14:42 < Cracki> for D you do need one value of history. you can lowpass those values before diffing them if they're too noisy
2020-05-26T15:14:56 < jpa-> (especially doubly-integrating systems, such as controlling torque of a motor to achieve a specific position)

2020-05-26T15:40:16 < Cracki> software people. yeah the real world is perfect and we can get away with sampling anywhere, so let's just sample the time that's the simplest to calculate, we don't need to do it right
2020-05-26T15:40:33 < jpa-> sync: why?
2020-05-26T15:41:06 < dongs> i thought proper way to do software uart is oversample 
2020-05-26T15:41:19 < dongs> and not fucking delay() inside exti handler
2020-05-26T15:41:21 < dongs> wtf is this garbage
2020-05-26T15:41:29 < Cracki> that would be fancy. I think sampling once in the middle of the bit time is good enough
2020-05-26T15:41:37 < Cracki> that's shit code
2020-05-26T15:42:07 < Ad0> lol
2020-05-26T15:42:19 < Cracki> the ST thingie uses a timer to trigger dma for sampling the port/pin at the middle of bit times
2020-05-26T15:43:01 < Cracki> I'd oversample if I had the additional task of recovering/syncing clock
2020-05-26T15:44:55 < Cracki> also lol at the 7 point reponse: ye says wait 1.5 bit times after start bit, but then waits 2/3 bit times

2020-05-26T16:05:16 < jpa-> sync: it depends totally on what you control, if your control output is torque (not velocity, not voltage) and feedback is position (not velocity), it's a doubly integrating process and those in general are not stable with P or PI controllers

2020-05-26T16:08:20 < Mangy_Dog> hurt my ears tryign to listen
2020-05-26T16:08:23 < sync> you have to have your loop frequencies and clamping under control but it works fine
2020-05-26T16:08:29 < jpa-> sync: and you control position of the motor? sounds strange that it is stable for you, unless your response time is very slow
2020-05-26T16:08:45 < sync> yes, of course I control the position
2020-05-26T16:10:01 < sync> I don't do position -> torque tho
2020-05-26T16:10:31 < qyx> PaulFertser: I have no explicit _sbrk
2020-05-26T16:10:58 < PaulFertser> qyx: it's likely provided by newlib, yes, but you can see it in the disassembly of your elf easily.
2020-05-26T16:13:56 < Cracki> newlib+freertos... is this cubemx-generated code by any chance?

2020-05-26T16:14:14 < Cracki> you don't even need the archive link
2020-05-26T16:14:18 < jpa-> sync: so, what do you do? cascade pid?
2020-05-26T16:14:30 < sync> yes
2020-05-26T16:14:33 < jpa-> yeah

2020-05-26T16:24:26 < qyx> it is not

2020-05-26T16:24:30 < Cracki> it should be
2020-05-26T16:24:55 < Cracki> oh wait, it may be _populated_ from a linker-defined thing
2020-05-26T16:25:21 < Cracki> he describes that somewhere, not sure on the specifics
2020-05-26T16:25:28 < Cracki> extern char _end;  // Defined in the linker script 
2020-05-26T16:25:50 < qyx> yeah, except there is no such thing

2020-05-26T16:26:41 < qyx> it works
2020-05-26T16:26:46 < qyx> damn thing
2020-05-26T16:26:50 < Cracki> on the page he says  extern char end asm("end"); // lowest unused RAM address, just beyond end of BSS.
2020-05-26T16:27:34 < Cracki> well, cubemx implementation he commented out says so

2020-05-26T19:08:22 < Cracki> in 2018, the dumb commies demanded that doctors have 30 hours/week reserved for publicly insured patients. public insurances cried that this would cause rising costs.

2020-05-26T19:25:33 < PaulFertser> Is that "own risk" basically the same as "deductible" in many other kinds of insurance products?

2020-05-26T19:26:05 < mawk> I suspect since it's all refunded by state in France all the labs are pumping up the prices
2020-05-26T19:26:14 < mawk> it's free money after all
2020-05-26T19:26:20 < mawk> just a line in the budget

2020-05-26T19:30:41 < PaulFertser> "Insurance companies use copayments to share health care costs to prevent moral hazard."
2020-05-26T19:30:54 < Cracki> for my braces they did that, and refunded the rest when "success" was declared. it was kinda like a security deposit.

2020-05-26T21:00:53 < jadew> benishor, yep, soldermask is shit
2020-05-26T21:01:04 < jadew> and the FR4 quality is also pretty bad

2020-05-26T21:03:40 < jadew> they sent it in two parts and the second part has not left HK yet
2020-05-26T21:03:48 < jadew> benishor, they're all shit
2020-05-26T21:03:56 < jadew> seeedstudio seemed to have the best quality
2020-05-26T21:04:41 < jadew> the only problem I had with them was the order number, which I didn't like
2020-05-26T21:05:09 < jadew> other than that, all the orders from them were of superior quality compared with the other ones
2020-05-26T21:05:17 < jadew> that said, I haven't ordered from them in a while, so that might have changed

2020-05-26T21:18:49 < jadew> seeedstudio - sometimes bad solder mask
2020-05-26T21:19:25 < jadew> the elecrow silkscreen has an additional property compared with the rest, it turns brown when you cook it
2020-05-26T21:20:01 < jadew> it's like they've only tested it to lead soldering temperatures
2020-05-26T21:20:28 < jadew> they fixed that at one point, by using different paint, but that one was almost transparent

2020-05-26T21:49:04 < mawk> in french speaking african countries they love taking names out of the calender, with the names of saints
2020-05-26T21:49:16 < mawk> but they have a few chances of messing up
2020-05-26T21:49:27 < mawk> for instance they could land on "national holiday"
2020-05-26T21:49:52 < mawk> which happened, say hello to baby fête nationale
2020-05-26T21:50:11 < mawk> they also give common names as first names, but that's less bad
2020-05-26T21:50:38 < mawk> well not even fête nationale but fêtnat, the abbreviation
2020-05-26T21:50:54 < mawk> because it doesn't fit in the calender

2020-05-26T22:54:00 < zyp> mipi what?
2020-05-26T22:54:37 < machinehum> Like a mipi camera on D-Phy
2020-05-26T22:55:00 < zyp> so CSI?
2020-05-26T22:55:03 < machinehum> Is the speed fixed... or? Like wtf do I even read to learn about how this shit works
2020-05-26T22:55:04 < machinehum> Yes
2020-05-26T22:55:22 < machinehum> All I've found is a bunch of stupid pdf's with dumb block diagrams
2020-05-26T22:55:43 < Cracki> pick something :D https://www.mipi.org/specifications
2020-05-26T22:55:49 < Cracki> I think they want your shekels
2020-05-26T22:56:00 < zyp> let's see, d-phy has a clock lane
2020-05-26T22:56:12 < Cracki> 1.1 has a public version
2020-05-26T22:56:23 < zyp> so data would be synchronous to the clock lane
2020-05-26T22:56:36 < Cracki> (or the command set)
2020-05-26T22:56:44 < zyp> c-phy and m-phy apparently have embedded clock (8b10b or something)
2020-05-26T22:58:09 < zyp> so I guess source is just sending at whatever rate it wants
2020-05-26T22:58:34 < zyp> and receiver locks on to the source rate
2020-05-26T23:01:12 < machinehum> Makes sense
2020-05-26T23:01:24 < machinehum> Thanks, looking through the camera datasheet as well
2020-05-26T23:07:17 < strata> after replacing this alternator yesterday, i got to thinking about supercaps as a starting battery replacement
2020-05-26T23:08:17 < strata> alternators are not designed to charge a dead starting battery, and it can damage them.
2020-05-26T23:09:06 < strata> i wonder if the very-much-shorter charging time for supercaps would be acceptable though?
2020-05-26T23:11:54 < zyp> sounds expensive
2020-05-26T23:13:02 < zyp> and what is the point?

2020-05-26T23:21:30 < Cracki> how does a mipi csi (csi2?) lane work? this excerpt from an imx6 sheet says 1 Gbps/lane ~ 62.5 MHz, so that's 16 bits per clock...
2020-05-26T23:21:33 < Cracki> https://community.nxp.com/thread/343107
2020-05-26T23:22:06 < Cracki> nvm, I guess that's pixel clock or something
2020-05-26T23:25:50 < BrainDamage> strata: supercaps as battery replacement are a thing, but your main concern is the leakage current
2020-05-26T23:26:01 < BrainDamage> they go flat on their own faster than lead acid bricks
2020-05-26T23:26:06 < strata> yes
2020-05-26T23:26:34 < strata> i would need a way to charge them before starting.
2020-05-26T23:26:59 < BrainDamage> there's lipo powered boosters
2020-05-26T23:27:01 < strata> or use house battery to keep them charged, and thus only using them for starting.
2020-05-26T23:27:27 < BrainDamage> or just turn on the engine every now and then
2020-05-26T23:27:57 < mawk> I see supercaps as battery that last 2 days for a small device
2020-05-26T23:28:05 < mawk> enough to cover mistakes and small outages
2020-05-26T23:28:43 < BrainDamage> the problem is not the energy they store, but that they discharge on their own even if not attached to anything
2020-05-26T23:28:59 < BrainDamage> once they are flat, you need to charge them enough to start the engine
2020-05-26T23:29:14 < BrainDamage> but unlike the lead acid batteries, you don't have to throw them away if they go flat
2020-05-26T23:29:21 < strata> right
2020-05-26T23:29:33 < strata> also they work at extreme temps where most lead acids (that are affordable) do not
2020-05-26T23:29:41 < strata> which is what intrigues me about them
2020-05-26T23:29:47 < BrainDamage> but you have another cons
2020-05-26T23:29:55 < BrainDamage> lead acid tolerate 16V fine
2020-05-26T23:30:04 < BrainDamage> they just bubble up some hydrogen that they vent
2020-05-26T23:30:18 < BrainDamage> if you want supercaps to tolerate that, it means another one or two in series
2020-05-26T23:30:22 < mawk> what would give them 16V ?
2020-05-26T23:30:28 < strata> mawk, alternator
2020-05-26T23:30:28 < BrainDamage> the alternator
2020-05-26T23:30:51 < BrainDamage> the voltage rail in a car is as unregulated as it gets
2020-05-26T23:30:53 < strata> in the supercap banks i see people putting in vehicles, they are building regulators
2020-05-26T23:31:50 < mawk> big diodes
2020-05-26T23:32:02 < strata> they are using some IC i can't recall what it is
2020-05-26T23:32:41 < mawk> fast thyristor thingie
2020-05-26T23:33:22 < strata> https://www.youtube.com/watch?v=dJklnvxLR5A
2020-05-26T23:33:53 < mawk> ah they just use regular transistors
2020-05-26T23:34:15 < strata> yeah there is another one that uses some voltage cut-off IC thingy
2020-05-26T23:34:52 < mawk> >you are very good at electronics!!!!!!!!!!!!! so good!

2020-05-26T23:35:47 < mawk> of a youtube comment in your video
2020-05-26T23:35:51 < strata> oh lol
2020-05-26T23:35:59 < BrainDamage> !!!!!!111111one
2020-05-26T23:36:00  * strata also does not read youtube video comments
2020-05-26T23:36:43 < mawk> a thyristor with some fast ic that cuts it off would work right ?
2020-05-26T23:36:51 < mawk> that both rectifies what goes to the cap, and protects it
2020-05-26T23:43:19 < BrainDamage> cutting off a thyristor requires as much current capability as the thyristor itself
2020-05-26T23:43:33 < BrainDamage> but you can use another in shunt to cut off the current
2020-05-26T23:52:09 < strata> lol total fail
2020-05-26T23:52:23 < strata> i thought i ordered a 12V PSU not a 5V

2020-05-27T02:07:33 < jadew> any good movies lately?
2020-05-27T02:08:01 < jadew> I felt deprived of movies in the past couple of years
2020-05-27T02:10:29 < jadew> I'm paying $2/mo for amazon prime and I'm not getting my money's worth
2020-05-27T02:11:41 < jadew> all the movies there are from when my parents were young
2020-05-27T02:12:53 < jadew> in the sci-fi section, the only movies that are newer than 2018 are bollywood ones
2020-05-27T02:13:18 < jadew> Tamil 2.0, with Skshay Kumab and Telugu 2.0, with Akshay Kumar
2020-05-27T02:13:34 < jadew> *Akshay on the first one too
2020-05-27T02:13:44 < jadew> Akshay Kumar, it's the same guy
2020-05-27T02:14:30 < jadew> could that be a language?

2020-05-27T02:14:35 < jadew> and 2.0 is the name of the movie?
2020-05-27T02:14:42 < jadew> there are 3 movies called 2.0 with that guy
2020-05-27T02:14:47 < specing> jadew: wiki has a list of sci-fi
2020-05-27T02:14:58 < specing> they are well seeded
2020-05-27T02:15:29 < qyx> I would say jadew wants some moving picture contents and not the list

2020-05-27T02:23:01 < qyx> yeah
2020-05-27T02:23:19 < qyx> my lora thing ist working finally

2020-05-27T02:23:43 < qyx> I am quite dissapointed with the possible data rate though

2020-05-27T02:24:21 < zyp> well, lora has never been about throughput, has it?
2020-05-27T02:24:26 < qyx> at least with the settings my current network provider uses

2020-05-27T02:31:55 < qyx> because 868MHz has this weird 0.1%/1% duty cycle restriction
2020-05-27T02:36:21 < zyp> not really weird
2020-05-27T02:37:53 < zyp> if you're gonna have a free use part of spectrum with enough tx power allowed to get good range, you'll have to limit duty to prevent overcrowding
2020-05-27T02:39:07 < zyp> what good is 10x more allowed duty gonna be to you if that just means the other stuff around you is pumping out 10x as much power that to you is just noise?

2020-05-27T02:48:36 < jadew> anyone got a system for storing aligator clips in an accessible manner while still keeping them shielded from dust?
2020-05-27T02:48:49 < jadew> I keep them in an ikea box and I hate going through it, looking for the right cable
2020-05-27T02:51:24 < zyp> what sort of alligator clips?
2020-05-27T02:51:45 < jadew> the kind you use to power things with
2020-05-27T02:51:57 < jadew> (banana plug to alligator)
2020-05-27T02:53:46 < dongs> i just leave mine connceted to a PSU
2020-05-27T02:53:51 < Cracki> it never occurred to me that alligator clips or anything you have them bite into would be sensitive to dust
2020-05-27T02:53:52 < dongs> what the fuck else would I do with it
2020-05-27T02:54:07 < Cracki> if they get dusty, you're not using them often enough :> random plastic box sounds simple enough to keep that away
2020-05-27T02:54:15 < dongs> i have liek 4 cables i made from silicone wire and random hobbyking alligator clips
2020-05-27T02:54:35 < jadew> Cracki, Romania has a climate that generates a lot of dust
2020-05-27T02:54:36 < Cracki> he probably has the hirschmann luxury editions
2020-05-27T02:54:49 < dongs> jadew: japan has more dust
2020-05-27T02:54:49 < Cracki> great I'll immigrate, I hate humidity
2020-05-27T02:54:51 < jadew> dongs, I don't like clutter
2020-05-27T02:55:03 < jadew> if I left everything connected it would be a nightmare
2020-05-27T02:55:04 < dongs> japan has chinese dust too
2020-05-27T02:55:09 < jadew> lol
2020-05-27T02:55:23 < Cracki> buy moar banana cables, put alligators on the tips, hang the cables
2020-05-27T02:55:27 < dongs> no really. chinks send dust clouds or something
2020-05-27T02:55:41 < Cracki> they do agriculture with brawndo or something
2020-05-27T02:55:47 < dongs> i prefer making my own out of like 14AWG silicone wire
2020-05-27T02:55:47 < jadew> we sometimes get dust from Sahara in here
2020-05-27T02:55:50 < Cracki> china does have huge deserts
2020-05-27T02:55:55 < dongs> they are so soft and easy to coil up and shit
2020-05-27T02:56:02 < strata> dust clouds of nanobots to turn humans into obedient compute nodes for alibaba
2020-05-27T02:56:15 < jadew> or was that Siberia?
2020-05-27T02:56:20 < jadew> must have been Siberia
2020-05-27T02:56:28 < zyp> I forgot where my alligator clips went
2020-05-27T02:56:31 < jadew> either way... it's some very nasty stuff that gets everywhere
2020-05-27T02:56:33 < Cracki> no, sahara sounds right, that shit gets blown up into europe
2020-05-27T02:56:51 < Cracki> siberia is a desert too I think but not hot enough to make dust
2020-05-27T02:57:11 < Cracki> went down teh toilet and drank some green radioactive liquid
2020-05-27T02:57:33 < jadew> zyp, so you're not using alligator clips at all?
2020-05-27T02:57:39 < jadew> what do you guys use?
2020-05-27T02:58:06 < Cracki> wapo: dust from northern africa across europe https://www.washingtonpost.com/resizer/KuOrkHCXmUM16zsY_WvRNWP_cio=/1007x0/arc-anglerfish-washpost-prod-washpost.s3.amazonaws.com/public/D5C7PV6XUNBDDNMSP7WZW25UTM.gif
2020-05-27T02:58:27 < Cracki> <- alligator clips but soldered onto some 1.5mm2 wire, not pluggable
2020-05-27T02:58:28 < jadew> Cracki, heh
2020-05-27T02:58:43 < zyp> jadew, I guess
2020-05-27T02:58:44 < Cracki> I have a few banana cables too but the alligators are double ended alligator
2020-05-27T02:59:19 < jadew> I use either alligators or some other types of clips
2020-05-27T02:59:19 < Cracki> I use alligators mostly to interface banana to dupont/2.54mm wires
2020-05-27T02:59:23 < Cracki> yes, janky
2020-05-27T02:59:25 < jadew> so I have lots of banana to something cables
2020-05-27T02:59:37 < zyp> I forgot where my banana cables went too
2020-05-27T02:59:54 < zyp> they're probably with the alligator clips in a box somewhere
2020-05-27T03:00:02 < jadew> right, I want some banana to dupont too
2020-05-27T03:00:13 < jadew> zyp, so how do you power your circuits?
2020-05-27T03:01:05 < zyp> usb?
2020-05-27T03:01:09 < Cracki> someone I know had a random makita battery in baton shape. got me to make a little plastic part that adapts the contacts for banana. quite handy.
2020-05-27T03:01:10 < zyp> screw terminals?
2020-05-27T03:01:31 < zyp> solder points?
2020-05-27T03:01:48 < Cracki> boss's creations use screw blocks or those pluggable screw things
2020-05-27T03:02:28 < Cracki> industrial wiring is all copper wire with ferrules crimped on the end so that goes well into screw blocks
2020-05-27T03:02:46 < Cracki> he's got a bunch of banana cables cut in half with ferrules on the cut ends
2020-05-27T03:03:12 < jadew> I guess there are more ways of doing things
2020-05-27T03:03:35 < jadew> I usually avoid soldering the power connector on most things that are in a prototype stage
2020-05-27T03:03:42 < Cracki> i'd buy banana cables on aliex if those plugs didn't look so cheap
2020-05-27T03:03:53 < jadew> I either solder some wires and use alligators on those
2020-05-27T03:04:09 < jadew> or use some clips directly on the connector's pads/holes
2020-05-27T03:04:13 < Cracki> for that case I take alligators, find the jaw with a tooth front and center, and hook that into the pad from the edge of the board
2020-05-27T03:05:02 < Cracki> even works with screw blocks sometimes. one jaw on the back side over the stub of the TH... thingie, other not quite into the terminal's front
2020-05-27T03:06:04 < zyp> jadew, when I solder wires to anything, I just make them long enough to screw them into the power supply
2020-05-27T03:06:25 < jadew> zyp, never crossed my mind to do it like that lol
2020-05-27T03:06:54 < zyp> IIRC when I still knew where my banana cables were, I used those with banana in one end and soldered the other to whatever

2020-05-27T03:07:08 < jadew> I probably did it at some point for some high current stuff, but I would see it as a waste of wire otherwise
2020-05-27T03:07:52 < zyp> I usually strip some scrap cat5 and use a pair when I need some test wires for some shit
2020-05-27T03:08:08 < jadew> ah, I used to do that too, but then I got good wire
2020-05-27T03:08:14 < zyp> https://bin.jvnv.net/file/rRJmm.jpg <- e.g. like this
2020-05-27T03:08:26 < jadew> the problem with that is that it's too rigid
2020-05-27T03:08:29 < jadew> and it can lift pads off
2020-05-27T03:08:42 < Cracki> take patch cable, it's not a single strand
2020-05-27T03:09:03 < zyp> yeah
2020-05-27T03:09:08 < Cracki> anything I solder to pads is copper bodge wire or fastened mechanically to the board
2020-05-27T03:09:29 < jadew> right, multi strand wire works great
2020-05-27T03:10:01 < Cracki> the installation cat cable is sturdy stuff. I gave my fingers punctures several times
2020-05-27T03:10:03 < jadew> I just bought two rolls of multi strand wire, different colors
2020-05-27T03:10:05 < jadew> and use that
2020-05-27T03:10:31 < jadew> I should probably get rid of the "waste" mentality tho
2020-05-27T03:10:38 < jadew> I have lots of wire...
2020-05-27T03:16:11 < zyp> IMO this is the perfect way to reuse patch cables after you wear out the retaining tabs
2020-05-27T03:17:23 < jadew> the color coding is useful too

2020-05-27T09:47:28 < upgrdman_> they use different wires?
2020-05-27T09:48:31 < jpa-> yeah, and power distribution at reasonable currents requires the cable to identify itself as having thick enough wires

2020-05-27T10:57:07 < upgrdman> smps pros: is it a bad idea to connect the sense pin of a buck regulator to the point AFTER a ptc fuse? in other words, to compensate for the drop across the fuse.
2020-05-27T10:57:28 < upgrdman> obviously the ptc would need to be rated for the input voltage then, but other than that, any problems?
2020-05-27T10:57:54 < dongs> sense pin? sensing what? you mean VFB?
2020-05-27T10:57:56 < upgrdman> not sure if it "bad" to do that, since the buck regulator might "fight" with the ptc if the fuse is near the tripping point
2020-05-27T10:58:00 < upgrdman> dongs, ya
2020-05-27T10:58:17 < dongs> just set your output voltage higher
2020-05-27T10:58:20 < dongs> to count for the drop
2020-05-27T10:58:34 < upgrdman> dongs, problem is the current draw has spikes :(
2020-05-27T10:58:50 < upgrdman> makes my LCD backlight flicker when the 3V3 rail flickers by 150mV
2020-05-27T10:59:08 < dongs> nice
2020-05-27T10:59:15 < upgrdman> ya. so pro, rite?
2020-05-27T10:59:26 < dongs> your buck converter is trash then if it cant handle sudden load
2020-05-27T10:59:51 < upgrdman> i also see that my ptc fuse rated at ~1ohm, but others that are only slightly more expensive are rated at ~150mOhm, so that might be a simple fix too
2020-05-27T11:00:04 < upgrdman> dongs, the problems isn't the convert. it's the drop across the fuse
2020-05-27T11:00:44 < mawk> if the ptc trips its resistance will increase too
2020-05-27T11:00:44 < upgrdman> that voltage across my PTC spikes between 10mV and 150mV :/
2020-05-27T11:00:52 < mawk> maybe forever
2020-05-27T11:01:06 < upgrdman> ya, im not tripping the fuse, just have spikes near the holding current rating
2020-05-27T11:01:14 < jpa-> upgrdman: it will depend on the buck regulator type, i.e. whether it relies on ripple to synchronize itself
2020-05-27T11:01:17 < mawk> well it may trip one day that's what I mean
2020-05-27T11:01:23 < mawk> since you put it there for a reason right
2020-05-27T11:01:23 < upgrdman> k
2020-05-27T11:01:28 < upgrdman> ya
2020-05-27T11:01:31 < mawk> or just remove it if it will never trip
2020-05-27T11:01:43 < Thorn> upgrdman you should be using a current source for lcd backlight, i.e. measure voltage across a shunt and pass that to Vfb
2020-05-27T11:01:44 < jpa-> why not put the fuse before the buck?
2020-05-27T11:01:51 < Thorn> then you shouldn't have any flicker
2020-05-27T11:02:03 < upgrdman> it should never trip, but i dont want my design burning down some SWAT team truck if an IC fails short-circuit
2020-05-27T11:02:43 < upgrdman> jpa-, theres a fuse on the power input, then multiple bucks to provide multiple rails. each rail then has its own fuse
2020-05-27T11:03:09 < upgrdman> to be safe, i dont want any one rail to be able to supply the amount of power required of all rails.
2020-05-27T11:03:45 < upgrdman> Thorn, overkill. and i might as well fix the root problem anyway. not good to have a 3V3 rail with 150mV of shit
2020-05-27T11:04:18 < jpa-> upgrdman: well, you could still have it per-buck before the buck
2020-05-27T11:04:32 < upgrdman> hmm, true
2020-05-27T11:04:50 < jpa-> (with the decoupling cap on the buck side of the fuse)
2020-05-27T11:04:55 < upgrdman> ya
2020-05-27T11:05:03 < jpa-> that has the extra benefit of isolating the buck noise from the common rail a bit
2020-05-27T11:05:51 < jpa-> which buck regulator are you using?
2020-05-27T11:06:07 < upgrdman> guess i'll see if the other ptc fuses rated at 150mOhm are good enough to solve this problem, if not, i guess pre-buck-ptc's will do the trick
2020-05-27T11:06:19 < upgrdman> STM ST1S14PHR
2020-05-27T11:07:45 < upgrdman> cheap, decently high-freq, and 48Vin
2020-05-27T11:08:02 < upgrdman> and no need for lots of passives to configure it
2020-05-27T11:10:04 < jpa-> putting the fuse in series with the inductor would be equal to having an inductor with higher series resistance, so it probably will work ok
2020-05-27T11:10:55 < jpa-> that design appears to take the sync through the capacitor in parallel with feedback resistor, so it will affect the control loop, but it can probably tolerate such resistance
2020-05-27T11:10:59 < dongs> upgrdman: fuse on each rail output is dumb, use a proper converter that has overcurrent sense
2020-05-27T11:12:12 < upgrdman> dongs, know of a cheap one that'll do 48Vin, up to 1Aout, and adjustable current sense in range of 500mA - 1A?
2020-05-27T11:12:25 < upgrdman> probably cost more than the stm shit and ptc i used.

2020-05-27T13:24:07 < zyp> https://www.ti.com/lit/ds/symlink/tps66020.pdf <- if I've got two of these, would it be safe to connect the VLDO terminals together?
2020-05-27T13:25:37 < zyp> page 18 suggests both the VIN and the VBUS paths are reverse protected, which is natural since you wouldn't want them to feed into each other
2020-05-27T13:28:38 < zyp> both devices would be connected to the same VIN source, so if VIN is present, it'll be present for both
2020-05-27T13:40:25 < chipant__> someone give me a suggestion, a newbie in firmware domain. I am actually not sure whether to go with RTOS or not. My software architecture mainly goes as : one modbus master stack, one modbus slave stack, some system tasks in infinite loop, fault handlers (not the one comes with ST), SD data logging (not in real-time though).
2020-05-27T13:41:24 < zyp> are you writing your own modbus stuff, or integrating existing code?
2020-05-27T13:46:40 < zyp> IME, an RTOS starts getting useful when you have several parts of the code that are independent enough that it's easier to handle communication between multiple threads than getting them to coexist peacefully in a single thread
2020-05-27T13:49:19 < zyp> if all your tasks can just be polled repeatedly by a single mainloop, multithreading might not be worth it, but once one task starts blocking the mainloop for longer than the latency requirements of other tasks, you probably want preemptive multithreading
2020-05-27T13:50:17 < zyp> and if you're integrating existing code, you might not have control of how long it blocks

2020-05-27T14:06:36 < chipant__> zyp, not writing the modbus on my own. Already adopted the freeModbusSlave and soon go for implementing the modbus master too.
2020-05-27T14:07:08 < chipant__> So I came to think that both the bus should be operated in real-time.
2020-05-27T14:07:35 < chipant__> and thus might require RTOS to handle(or organize) them. 
2020-05-27T14:08:35 < chipant__> was also wondering that is there any reliable modbus master port to STM32 (as like freeModbus Slave) ?
2020-05-27T14:09:17 < zyp> karlp might know

2020-05-27T17:10:20 < Cracki> that's a novel idea

2020-05-27T17:11:51 < Cracki> what's next, fishing in short shorts?
2020-05-27T17:12:27 < Cracki> her "early life" is a bit sparse but father being a service station owner sounds ok
2020-05-27T17:13:33 < Laurenceb> yeah I remember that games console thingy, it was kind of cool
2020-05-27T17:13:39 < Laurenceb> the only pro thing she ever did
2020-05-27T17:14:07 < Laurenceb> inb4 she copypastered the sores
2020-05-27T17:15:15 < Laurenceb> we used to play it in the school common room, inbetween watching ogrish videos
2020-05-27T17:15:33 < Laurenceb> and hanging out on ebaums world
2020-05-27T17:16:29 < Laurenceb> happy days
2020-05-27T17:19:56 < zyp> Si5332 is pretty wild
2020-05-27T17:20:16 < zyp> I'm not sure what clocks my FPGA shit needs, but apparently that doesn't matter because Si5332 can make them all anyway
2020-05-27T17:20:55 < Cracki> >6/8/12-Output Any-Frequency
2020-05-27T17:20:56 < emeb> Si makes a whole lot of really wild & wondeful stuff.
2020-05-27T17:21:10 < Laurenceb> thats whats inside LeoNTP
2020-05-27T17:21:24 < emeb> boggles the mind how they get all that onto such tiny parts.
2020-05-27T17:21:38 < Cracki> jitter in FEMTOseconds, not picoseconds
2020-05-27T17:21:39 < Laurenceb> together with wacky high stability xtal 
2020-05-27T17:22:02 < Laurenceb> Cracki: thats short term jitter tho
2020-05-27T17:22:06 < Cracki> ic
2020-05-27T17:22:18 < Laurenceb> you need a stable xtal to get good NTP performance with GPS
2020-05-27T17:22:45 < Laurenceb> there is a window in the allen variance plot where the xtal is needed to stabilise it
2020-05-27T17:23:14 < zyp> I'm playing around with the clockbuilder tool now, telling it «give me 12, 12.288, 25, 60 and 125 MHz» and it's like «sure, let's spin up the VCO to 2.4GHz and derive them all from that»
2020-05-27T17:23:43 < Laurenceb> LeoNTP used flexi pcb with xtal on the end, then "potted" in wax and mounted within some silicone rubber foam
2020-05-27T17:24:47 < Cracki> can the VCO do 2.4 ghz
2020-05-27T17:24:48 < emeb> zyp: USB and I2S and ethernet and....
2020-05-27T17:25:05 < zyp> dunno, I'm just making up values to see what it comes up with
2020-05-27T17:25:26 < Cracki> it should come up with in-spec values
2020-05-27T17:25:41 < Cracki> or it better
2020-05-27T17:25:51 < Laurenceb> but LeoNTP was giving picoseconds jitter out of the ethernet O_o
2020-05-27T17:26:04 < emeb> did some stuff w/ Si570 and Si5351 a while back. They're interesting to drive from STM32.
2020-05-27T17:26:21 < emeb> needs some odd calcs to do arbitrary realtime updates
2020-05-27T17:26:50 < zyp> it's using the two fractional dividers to generate 125 (2400/19.2) and 12.288 (2400/195.3125) and a plain /8 divider to get 300 that the remaining values are derived from with the output dividers

2020-05-27T17:29:46  * emeb used to pay ~$1800/yr for matlab maintenance.
2020-05-27T17:29:50 < Laurenceb> with latest versions plotting is finally nice to use
2020-05-27T17:30:16 < Cracki> hobbyists pay the iron price, pr0s charge it to the customer

2020-05-27T17:30:22 < emeb> yep
2020-05-27T17:30:24 < Cracki> >nice plotting
2020-05-27T17:30:44 < emeb> matplotlib output actually looks nicer to me than matlab tho
2020-05-27T17:32:03 < Cracki> they send their work to improving the whole ui. those matlab "live" notebooks are jupyter but nicer
2020-05-27T17:32:42 < zyp> emeb, I want the board I'm making to be capable of various serdes experiments, so I figure I'll generate two separate refclks for that, and then a generic clock or two for the fpga fabric itself, along with both refclk inputs and outputs from the board
2020-05-27T17:32:47 < Cracki> i find matlab plots a bit bare... haven't figured out how to make them interactable, i.e. point at data and get a callout
2020-05-27T17:33:13 < zyp> and while I'm at it, it's tempting to just feed the onboard FT2232H 12MHz from a spare output as well
2020-05-27T17:33:50 < emeb> zyp: makes sense. I'm noodling with a little dedicated SDR board & doing similar stuff.
2020-05-27T17:34:22 < zyp> https://bin.jvnv.net/file/Tirzp.png <- did you see I finished connecting the sodimm?

2020-05-27T18:43:47 < bitmask> which should I get
2020-05-27T18:43:53 < zyp> both
2020-05-27T18:44:05 < bitmask> boo
2020-05-27T18:46:27 < Cracki> is that watts input or watts output
2020-05-27T18:47:27 < Cracki> the lumens figure is useless since that is using the response curve of human eyes ("visible light") and that stuff is mostly invisible
2020-05-27T18:48:06 < Cracki> I guess get the cheapest? you can't print fast enough to make that stage the bottleneck
2020-05-27T18:48:32 < Cracki> heh both 19 bucks, pick the 20w then
2020-05-27T18:49:52 < bitmask> what are you talking about
2020-05-27T18:50:11 < Cracki> one of them gives a figure of 40 lm, the other doesn't say
2020-05-27T18:50:18 < Cracki> what are you talking about
2020-05-27T18:50:20 < bitmask> its not for a printer first of all, and if it were its for the final curing stage, not while printing
2020-05-27T18:50:28 < Cracki> exactly, for curing
2020-05-27T18:50:40 < Cracki> and if you cure things that come out of the printer, ... that's a pipeline
2020-05-27T18:50:55 < Cracki> and if you need to cure longer than a print takes to print, that's a bottleneck
2020-05-27T18:50:55 < zyp> as long as curing is faster than printing, it's fast enough
2020-05-27T18:51:02 < Cracki> I hope that's understandable
2020-05-27T18:51:02 < bitmask> second of all, I linked to the 20w version which is $10 more
2020-05-27T18:51:07 < zyp> assuming throughput is all that matters
2020-05-27T18:51:20 < Cracki> look, maybe the links don't work
2020-05-27T18:51:22 < zyp> but a shorter curing time would give less latency
2020-05-27T18:51:30 < bitmask> ok fine, i'll just go with the 6w
2020-05-27T18:51:35 < Cracki> one is 20 watt 20 bucks, the other is 6 watt 20 bucks, or 20 watt 47.99
2020-05-27T18:52:26 < bitmask> not sure what the first one you are looking at is
2020-05-27T18:52:30 < Cracki> you say it's not for a printer. is it for decorative lighting then
2020-05-27T18:52:33 < bitmask> its 10w $20 / 20w $30
2020-05-27T18:52:49 < bitmask> curing dry film and solder mask
2020-05-27T18:53:00 < bitmask> so I know its enough for that
2020-05-27T18:53:02 < Cracki> i see one 20w $30 and that's "non-water" vs "slim" for $20
2020-05-27T18:53:16 < bitmask> but if I want to get a resin printer at some point it would be nice to already have a final curing light
2020-05-27T18:53:39 < bitmask> the slim is $30 for me
2020-05-27T18:54:26 < Cracki> I have no experience with solder mask curing. I'd look for most uniform light and also consider precise exposure times... more power means it's happening faster, so you have to watch the time more closely
2020-05-27T18:54:47 < zyp> that
2020-05-27T18:55:13 < bitmask> agreed, i'll go with the 6w

2020-05-28T00:08:47 < mawk> well it's because of the browser
2020-05-28T00:08:51 < mawk> you can request permission only after an interaction
2020-05-28T00:08:57 < Cracki> sure
2020-05-28T00:09:02 < mawk> so you got to make sure the user is going to click yes, so you show a fake notification dialog
2020-05-28T00:09:11 < Cracki> throw up a widget with a button that says "yes try asking for permissions"
2020-05-28T00:09:13 < mawk> otherwise if the user clicks no you lost your chance to every display notifications again

2020-05-28T00:10:38 < Steffanx> Why so evil mawk
2020-05-28T00:10:56 < mawk> the website absolutely needs permissions

2020-05-28T00:11:22 < mawk> as every website, for instance a recipe site cannot work without GPS location and notifications
2020-05-28T00:11:34 < Steffanx> So whos matthijs, mawk?

2020-05-28T00:35:37 < zyp> no, V_IH
2020-05-28T00:35:43 < zyp> 0.7*5 is 3.5
2020-05-28T00:35:56 < Ultrasauce> i guess you use vcc = 3.3 in that case?
2020-05-28T00:36:15 < Cracki> so... vcc 5v for 5v outputs means you have a problem, or does it have a separate output supply?
2020-05-28T00:36:21 < Ultrasauce> doesnt look like the input voltage is constrained to <vcc
2020-05-28T00:36:54 < Ultrasauce> so it doesnt support every level shifting use case
2020-05-28T00:37:01 < Cracki> that table is inconsistent. they give factors of vcc for 1.65..95 volts and 4.5..5.5v but in between they give no factor

2020-05-28T01:13:12 < zyp> I'm gonna put a stm32g0 for usb-pd/power handling/whatever on the board, and I want both that and the fpga to be able to control the leds, a mux seems like an elegant way to achieve that
2020-05-28T01:13:27 < zyp> especially if it would take care of voltage translation as well
2020-05-28T01:14:16 < Thorn> isn't there an open source PD core?
2020-05-28T01:14:38 < zyp> for the fpga?
2020-05-28T01:14:54 < zyp> that's not what I want
2020-05-28T01:15:15 < zyp> I wanna be a PD sink, run everything from a PD input
2020-05-28T01:15:54 < zyp> TPS66020 LDO powers the g0, g0 negotiates a PD contract and turns on the main regulators that starts the FPGA
2020-05-28T01:16:28 < zyp> (also configures regulators and whatever needs to happen before the fpga boots)
2020-05-28T01:17:00 < zyp> which is why it'd be nice to be able to use the leds to indicate errors from the mcu if the fpga can't start
2020-05-28T01:17:06 < zyp> and then hand over control to the fpga afterwards
2020-05-28T01:17:39 < zyp> but bedtime now, I'll dick around with that more tomorrow
2020-05-28T01:27:00 < qyx> zyp: I assembled my laser-cut subrack today
2020-05-28T01:27:08 < qyx> I mean the side panels
2020-05-28T01:27:31 < qyx> I still cannot find a suitable way of cutting the alu profiles

2020-05-28T03:56:32 < jadew> anyone died?
2020-05-28T03:56:58 < jadew> oh, they just sat there...

2020-05-28T04:12:01 < Cracki> rangefinders... I'm not sure I understood the one example. at 19:35 the views give me an actual cross with depth above the ship. I figure the adjustment dial lets me move either the ship or the cross in "distance" which can then be read off the dial... I think he talked about focus instead, which sounds implausible

2020-05-28T04:25:41 < Cracki> what's that
2020-05-28T04:25:50 < jadew> german TV show

2020-05-28T04:26:24 < Cracki> wp says dutch, close enough
2020-05-28T04:26:29 < jadew> ah
2020-05-28T04:26:32 < jadew> sounds the same to me
2020-05-28T04:26:35 < jadew> sorry
2020-05-28T04:26:45 < Cracki> medical student, secret society, that?
2020-05-28T04:26:50 < jadew> yeah
2020-05-28T04:28:24 < Cracki> episode summaries sound crazy
2020-05-28T04:28:33 < jadew> I didn't read anything
2020-05-28T04:29:06 < jadew> I just started watching, the fact that it's not in a language I can understand is a bit of a let down, I was hoping to also read something

2020-05-28T04:31:53 < jadew> they did have some great documentaries when I was young tho
2020-05-28T04:32:03 < Cracki> maybe quit netflix, pay 5 bucks a month for ipredator vpn, and pay the iron price for the rest
2020-05-28T04:32:33 < jadew> I'm afraid to google that
2020-05-28T04:32:45 < Cracki> the best our public broadcast does is weekly episodes of a zoo, and they engaged belgians to make a series on fire fighters and EMTs
2020-05-28T04:33:11 < jadew> ah, that sounds like shit
2020-05-28T04:33:29 < Cracki> ipredator because swedes had the IPRED legislation. something about privacy.
2020-05-28T04:33:46 < jadew> we used to get really good documentaries on wild life, geography, science, the classics
2020-05-28T04:33:51 < Cracki> well the zoo stuff is fun, and the firefighters/emts series is very well made and also interesting
2020-05-28T04:35:00 < Cracki> no voiceover/narrator, the heroes themselves explain some things from a kind of debriefing
2020-05-28T04:35:01 < Thorn> emeb_mac do you know about this https://www.youtube.com/playlist?list=PL8bdFhL3DcsZURM9ZpExX7w7e15RQ0kyk

2020-05-28T10:00:56 < upgrdman> any windows pros awake? if you resize a window, it often lags behind by a frame, presumably because the cursor is drawn just before vsync, which is after the gui was drawn. but some apps do it perfect... window resizing is 100% in sync with the mouse, no latency. any idea how? guessing some sort of API to tell windows to give it a late draw call or something like that?

2020-05-28T11:24:06 < PaulFertser> "I  can not honestly recommend buying one of these watches. Timex has responded to every question I have sent them, which is impressive for a company. However, Timex failed to answer every single one of my questions"
2020-05-28T11:26:50 < benishor> nice :)
2020-05-28T11:32:49 < PaulFertser> http://www.bobdbob.com/~protius/timex/final.html has description of the CRT flickering protocol and it's kinda interesting because it's not like some display area is either lit on or not. It seems the idea is to transfer 8 bits per screen refresh even though just a single light sensor is present on the device.
2020-05-28T11:34:49 < PaulFertser> Ain't that a rather neat hack?
2020-05-28T11:35:32 < PaulFertser> And for the next version they managed to get 16 bits at a time.

2020-05-28T14:44:55 < Steffanx> Lol windows. Open an explorer window(win+e), press ctrl+f, press ctrl+v and 9 out of 10 times it will not show the text you copied but a nice square. Such windows feature.

2020-05-28T14:52:18 < Steffanx> Its just pasting to fast tcth.
2020-05-28T14:52:36 < Steffanx> Copying is for noobs
2020-05-28T15:00:11 < aandrew> that nice square is a window. it is a feature.
2020-05-28T15:06:06 < dongs> Steffanx: you talking about file search in explorer box?
2020-05-28T15:06:40 < dongs> position your mouse cursor to the left of the search icon, but to the right of reload icon until it turns into a draggable cursor, then drag that line to the left to expand the searchbox.
2020-05-28T15:06:55 < Steffanx> Yes, the search box in the file explorer

2020-05-28T15:25:17 < wut21s> hey guys. I'm tinkering with the rtc for stm32f767zi but can't get it to "remember" the date after I power-cycle. Nonetheless its backup registers aren't lost. Any tips on how to debug this?
2020-05-28T15:26:33 < wut21s> vbat is powered
2020-05-28T15:28:48 < zyp> are you using a library to access the rtc, or poking the registers directly?
2020-05-28T15:30:10 < wut21s> I'm using chibios, but actually for the backup register I'm writting directly
2020-05-28T15:31:40 < Cracki> could chibios be at fault
2020-05-28T15:32:00 < zyp> my guess is that you're somehow not checking whether the rtc is already running and just reinitialize it unconditionally
2020-05-28T15:32:24 < zyp> which might mean you're calling the wrong library function
2020-05-28T15:33:15 < zyp> what happens if you do a system reset without power cycling?
2020-05-28T15:34:04 < wut21s> hm that's a good point I'm going to try
2020-05-28T15:38:16 < zyp> I found out what to do about my led stuff, I'm just gonna do it this way: https://bin.jvnv.net/file/HxpO8.png
2020-05-28T15:38:27 < zyp> that's an OR gate instead of a mux
2020-05-28T15:38:46 < dongs> heh nice
2020-05-28T15:39:15 < zyp> just need to make sure the mcu and the fpga doesn't try to drive them at the same time, but that shouldn't really be that hard
2020-05-28T15:39:44 < Cracki> inputs idle low hm
2020-05-28T15:39:56 < zyp> yeah, and I'm gonna add pulldowns as well
2020-05-28T15:41:09 < zyp> in theory I could skip the gate and tristate the drivers that are not in use, but those are on different supplies, I don't want the mcu feeding into the unpowered fpga
2020-05-28T15:41:27 < zyp> and either way 3.3V is too low to meet 0.7*Vdd for the leds
2020-05-28T15:41:50 < zyp> so it should work out well enough like that
2020-05-28T15:42:52 < Cracki> simple, elegant
2020-05-28T15:44:12 < zyp> kinda seems a bit overkill to use adressable leds for indicators, but still, 4x RGB with one wire instead of twelve is great
2020-05-28T15:46:55 < zyp> especially when controlling them from multiple sources
2020-05-28T15:48:16 < zyp> on qspi flash, is the 8x6 BGA with 24 balls in a 5x5-1 pattern as common as it seems?
2020-05-28T15:56:03 < wut21s> zyp: sorry it took me a bit to test. So just by reseting the uc I don't lose the datetime
2020-05-28T16:01:29 < zyp> okay, that suggests it's not an initialization error
2020-05-28T16:01:45 < zyp> but something actually related to preservation on vbat
2020-05-28T16:02:48 < zyp> next sanity check I'd do is to power cycle it and peek the RTC registers in the debugger before the code runs
2020-05-28T16:03:16 < zyp> to break in the debugger after a power on reset, you may have to change the software or something
2020-05-28T16:03:42 < zyp> since you wouldn't have time to attach the debugger otherwise
2020-05-28T16:04:07 < wut21s> can I just check it before hal and os initialization? So putting a breakpoint before those calls
2020-05-28T16:04:34 < wut21s> or has to before the reset handler run
2020-05-28T16:04:38 < zyp> yes, but how are you gonna put a breakpoint there before it runs?
2020-05-28T16:04:49 < zyp> nah, just before the hal starts touching the rtc is fine
2020-05-28T16:05:08 < zyp> thing is that powering down the board obviously detaches the debugger
2020-05-28T16:05:09 < wut21s> what I meant is put a breakpoint on those lines and debugger stopping there before the call
2020-05-28T16:05:31 < zyp> so when you power it up, you need to keep the hal from running until debugger has attached
2020-05-28T16:05:45 < zyp> maybe add a wait for a gpio or something at top of main()
2020-05-28T16:06:28 < wut21s> yeah that might work

2020-05-29T00:42:21 < Thorn> qyx coin cell is the main suplpy (this is a radio sensor node) but there's also a usb interface so I want to power it from usb when it's connected
2020-05-29T00:42:21 < mawk> also same number of 1 and 0 on a line or column, also no two columns that are the same, no two lines that are the same

2020-05-29T01:07:44 < Cracki> 0.35mm, 13.8 mil. sounds not impossible but...
2020-05-29T01:13:03 < ds2> anyone know if 30G wire has a chance of fitting on a 0.4mm pitch set of pins?
2020-05-29T01:13:21 < Cracki> 30 awg?

2020-05-29T12:51:21 < dima> what's the best way to stop the SPI clock at the end of read-only DMA transaction? I'm using SPI_CR1_BIDIMODE=0, SPI_CR1_RXONLY=1, the chip is stm32f401
2020-05-29T12:51:48 < dima> the reference manual (RM0368) does not say anything about this, but the diagram in Fig.206 (Reception using DMA) sort of implies that the SPI clock would stop on its own once the last byte is transferred.
2020-05-29T12:53:40 < dongs> yes why wouldnt it?
2020-05-29T12:53:48 < dongs> ive done DMA SPI on 401 and i dont recall having any issues
2020-05-29T12:54:12 < dongs> what are you seeing?
2020-05-29T12:54:13 < dima> well, it does not stop
2020-05-29T12:54:28 < dongs> did you configure yotur DMA properly with transfer size and such?
2020-05-29T12:54:31 < dima> I can see on the oscilloscope that the clock is still ticking
2020-05-29T12:54:36 < dima> I did
2020-05-29T12:54:39 < dongs> make sure its not circular or somethign
2020-05-29T12:55:33 < dima> The DMA transaction stops when NDTR gets down to 0, I get the interrupt at the end of it
2020-05-29T12:55:41 < dima> no, it's not circular
2020-05-29T12:56:36 < dima> if I set RXONLY=0 and configure both RX and TX streams then it works fine
2020-05-29T12:57:19 < dongs> idk wat to tell you. i've got 16bit DMA, i set NDTR to size, enable dma_cmd for tx, enable the DMA stream. i'm not using IRQs so im just polling for TX_DMA_TCIF for completeness, then wait for FLAG_TXE, then wait for FLAG_BSY, then clear the flags, disable DMA stream, and spin until SxCR_EN is high. that concludes the transaction.
2020-05-29T12:57:26 < dongs> i am using tx only stream
2020-05-29T12:57:56 < dima> ah, that's the major difference
2020-05-29T12:58:00 < dongs> er (spin until _EN is low)
2020-05-29T12:58:16 < dima> in your case the clock is driven by the TX
2020-05-29T12:58:35 < dongs> are you doing SPI master but for reads?
2020-05-29T12:58:36 < dima> whenever your write something into SPI_DR it starts ticking
2020-05-29T12:58:39 < dima> yes
2020-05-29T12:59:04 < dima> but with RXONLY=1 the clock start as soon as you enable the SPI
2020-05-29T12:59:19 < dima> and stops only when you disable it
2020-05-29T13:00:47 < dongs> you might have to setup dummy write DMA with memory/periph increases set to false
2020-05-29T13:00:56 < dima> but the DMA controller does not disable the SPI at the end of transaction
2020-05-29T13:00:57 < dongs> and just have it write 0xaa or something.
2020-05-29T13:01:08 < dongs> you should disable the channel yourself once youre done receiving
2020-05-29T13:01:12 < dongs> you are doing that right?
2020-05-29T13:01:19 < dima> yeah, I can do that
2020-05-29T13:01:26 < dima> that would work
2020-05-29T13:02:25 < dima> but what's the point of RXONLY=1 then?
2020-05-29T13:02:44 < dima> seems pretty useless to me
2020-05-29T13:03:58 < dima> I thought it would be nice to use only one DMA channel instead of two
2020-05-29T13:04:14 < dima> but I don't see any way to make it work
2020-05-29T13:05:20 < dima> if I disable the SPI myself in the DMA isr, I can not do it fast enough
2020-05-29T13:06:21 < dima> so the slave gets a few more ticks and starts sending the next byte
2020-05-29T13:08:14 < dongs> https://community.st.com/s/question/0D50X00009XkafjSAB/resolvedcant-get-spi-clock-to-stop-properly-rxonly this seems related
2020-05-29T13:08:52 < dongs> and yeah looks like you need to kill SPI to stop the clocks
2020-05-29T13:08:55 < dongs> good job ST
2020-05-29T13:10:06 < dima> yep, that's my problem exactly
2020-05-29T13:10:19 < dima> thanks
2020-05-29T13:11:00 < dongs> you could probably ghetto up SPI slave, generate clock using TIMx, and then configure timer to do x clocks and do slave spi read with DMA
2020-05-29T13:11:10 < dongs> if you want to have exact control over the clock counts.
2020-05-29T13:11:49 < dima> meh, I'd rather set RXONLY=0 and do a dummy write on the TX channel
2020-05-29T13:12:02 < dongs> yep, if you got DMA resources free thats probably the cheapest way.
2020-05-29T13:18:20 < zyp> I assume RXONLY=1 still does RXNE flow control, and if so I'd expect it to work if you just make the DMA request a bit shorter than the number of bytes you want to receive
2020-05-29T13:19:29 < zyp> a bit shorter depending on how many bytes fits in the peripheral buffer, IIRC some have room for one, some have a three or four byte FIFO
2020-05-29T13:20:32 < zyp> but let's say you wanna transfer 20 bytes, set up a DMA job for 19
2020-05-29T13:20:48 < zyp> once it completes, wait for RXNE, then turn off the peripheral before reading out the last byte
2020-05-29T13:21:12 < zyp> but yeah
2020-05-29T13:21:13 < dima> zyp: I thought so, but the clock keeps ticking even if I don't read anything from SPI_DR
2020-05-29T13:21:22 < dima> so there is no flow control
2020-05-29T13:21:27 < zyp> weird
2020-05-29T13:21:37 < dongs> according to that post hes not wrong
2020-05-29T13:21:40 < zyp> oh well, dummy bidirectional is cleaner anyway
2020-05-29T13:21:46 < dongs> idk, i would just spin up a 2nd DMA or use timer/slave mode
2020-05-29T13:21:56 < zyp> yeah
2020-05-29T13:22:24 < dongs> you can even abuse MOSI as a clock of some kind by transmitting shit like AA or etc
2020-05-29T13:22:52 < dima> hehe
2020-05-29T13:22:54 < dongs> or use it to generate muzak

2020-05-29T14:42:10 < strata> business as usual
2020-05-29T14:43:10 < strata> the cop was paid to bend the knee so the media could get a distraction from covid-19 long enough for it to spread for wave 2.
2020-05-29T14:43:28 < strata> the ensuing protests justify the deployment of national guard - who will remain on the streets
2020-05-29T14:43:50 < strata> and then in a couple months, "hi. i'm barrack corona. i'm back."
2020-05-29T14:44:50 < strata> tl;dr business as usual. i hope more police stations and agenda 2030 stack & pack apartment buildings get burned down. it's a beautiful sight.

2020-05-29T16:28:55 < Mangy_Dog> and im front he uk
2020-05-29T16:29:07 < Mangy_Dog> i dont fully trust our police either but in america its just a whole other level
2020-05-29T16:29:19 < Mangy_Dog> it was always known that the police in america were instatutionally racist
2020-05-29T16:29:30 < Mangy_Dog> but since the la riots it was kinda kept under wraps
2020-05-29T16:29:56 < Mangy_Dog> but it seems since trump has been around its like.... All out racist now... no mask no cover ups... fuck it... im racist and proud...
2020-05-29T16:30:03 < Mangy_Dog> its utterly insane
2020-05-29T16:30:13 < Mangy_Dog> i am genuingly fucking shocked at that video
2020-05-29T16:32:38 < PaulFertser> Mangy_Dog: you have to take into account that people in the US carry handguns and so the police is naturally inclined to act fast and somewhat violently when they're feeling a threat. It's not applicable to this specific CNN reporters arest of course.

2020-05-29T16:39:46 < dongs> but yeah, fuck yeah america
2020-05-29T16:39:59 < dongs> let's jsut give everyone guns
2020-05-29T16:40:07 < emeb> this is fine
2020-05-29T16:40:43 < Mangy_Dog> im just so glad not to live in america
2020-05-29T16:40:54 < Mangy_Dog> but that shit is uncontrollably messed up
2020-05-29T16:41:09 < PaulFertser> btw, the killing of that unfortunate person, was it completely unwarranted? It would be odd to assume cops were just doing that without any justification in the middle of a street.
2020-05-29T16:41:21 < Mangy_Dog> Totally unwarrented
2020-05-29T16:41:25 < Mangy_Dog> utterly and fully
2020-05-29T16:41:56 < PaulFertser> But how come? Were they high or something?
2020-05-29T16:42:08 < Mangy_Dog> no just used really hard tatics on him
2020-05-29T16:42:16 < Mangy_Dog> tackled him to the ground when he wasnt resisting or anything 
2020-05-29T16:42:22 < Mangy_Dog> and then crushed his windpipe with there knee
2020-05-29T16:42:47 < Mangy_Dog> the police account was... They wanted to talk to him about some counterfiet notes
2020-05-29T16:43:41 < PaulFertser> But this seems to be too risky no matter how you look at it.
2020-05-29T16:43:57 < PaulFertser> Do they carry bodycams there?
2020-05-29T16:44:08 < Mangy_Dog> it was captured and leaked i think
2020-05-29T16:44:11 < Mangy_Dog> but not all of it
2020-05-29T16:44:19 < Mangy_Dog> thats the othe rthing too
2020-05-29T16:44:38 < Mangy_Dog> many officers seem to be turning off there cams before going to "talk" to black people
2020-05-29T16:44:58 < Mangy_Dog> also cameras also randomly turn on and off or something
2020-05-29T16:44:59 < Mangy_Dog> anyway
2020-05-29T16:45:02 < Mangy_Dog> it happened
2020-05-29T16:45:06 < Mangy_Dog> it was clearly wrong
2020-05-29T16:45:43 < PaulFertser> Either we do not know something essentials or the policemen were out of their minds.
2020-05-29T16:45:46 < Mangy_Dog> I was against teh violent side of the protesting... its not fair on the innocent bloke who had his livly hood destroyed because some one wanted to burn his building...
2020-05-29T16:46:06 < Mangy_Dog> but at the same time all this shit... and just seeing how the police just arrested a CNN guy because hes black
2020-05-29T16:46:09 < PaulFertser> Because even if they are super-evil cruel and merciless murderers it wouldn't make any sense to do it that way.
2020-05-29T16:46:13 < Mangy_Dog> the police and the gov there deserve everything they get
2020-05-29T16:46:16 < mawk> I'm not sure you can call that institutional racism
2020-05-29T16:46:19 < Mangy_Dog> every petrol bomb
2020-05-29T16:46:19 < mawk> it's a pretty bold claim
2020-05-29T16:46:22 < Mangy_Dog> avery stone
2020-05-29T16:46:29 < Mangy_Dog> mawk it is
2020-05-29T16:46:36 < Mangy_Dog> theres no denying it now
2020-05-29T16:46:37 < mawk> you can call it widespread racism in the police culture if you want
2020-05-29T16:46:48 < mawk> but for it to be institutional you have to find explicit orders from hierarchy
2020-05-29T16:47:16 < Mangy_Dog> while i dont fully expect that to be the case........... i wouldnt be shocked if it was
2020-05-29T16:47:30 < Mangy_Dog> not in todays america
2020-05-29T16:47:34 < Mangy_Dog> not with trump in the whitehouse
2020-05-29T16:47:41 < emeb> Part of the problem is that there are effectively two chains of command in most police organizations
2020-05-29T16:47:47 < strata> the police didn't "just arrested a CNN guy because hes black" - that was theatre.
2020-05-29T16:48:03 < Mangy_Dog> why else did they arrest him?
2020-05-29T16:48:10 < strata> for theatre
2020-05-29T16:48:12 < strata> it was staged
2020-05-29T16:48:13 < emeb> In this case, the police officers union has very different ideas about proper policing than the actual chain.
2020-05-29T16:48:15 < Mangy_Dog> they arrested a latino cnn reporter as well
2020-05-29T16:48:21 < Mangy_Dog> but left the white one alone
2020-05-29T16:48:31 < strata> yes Mangy_Dog. it's for theatrics.
2020-05-29T16:48:41 < Mangy_Dog> whos?
2020-05-29T16:48:42 < strata> you're watching reality television
2020-05-29T16:48:52 < Mangy_Dog> whos narative is that?
2020-05-29T16:48:53 < Mangy_Dog> CNN?
2020-05-29T16:48:58 < Mangy_Dog> did they tell the police to do it?
2020-05-29T16:48:58 < strata> yes
2020-05-29T16:49:02 < strata> yes
2020-05-29T16:49:05 < Mangy_Dog> really?
2020-05-29T16:49:20 < strata> we don't know for sure. but highly likely.
2020-05-29T16:49:24 < Mangy_Dog> do you really believe that?
2020-05-29T16:49:42 < strata> just like that cop that got busted a few days ago dressed up in full battle gear getting ready to destroy buildings.
2020-05-29T16:49:42 < Mangy_Dog> i know that american news is built on hype and sensationalism
2020-05-29T16:49:49 < strata> and the protesters caught him
2020-05-29T16:49:54 < Mangy_Dog> but i really dont think the CNN told them to get arrested

2020-05-29T16:50:34 < strata> the police are complicit
2020-05-29T16:50:39 < Mangy_Dog> i would say theres a limit to it
2020-05-29T16:50:52 < Mangy_Dog> and in this case it just showed the insanity of american police now

2020-05-29T17:16:23 < mawk> Mangy_Dog: in france the police hits white people and lets the black people pretty much alone
2020-05-29T17:16:28 < mawk> it's not black and white (no pun intended)

2020-05-29T17:24:02 < PaulFertser> mawk: is an honestly non-violent protest possible in France? It seems that the yellow vest movement is not particularly peaceful.
2020-05-29T17:24:12 < Mangy_Dog> utterly unexpected level of over reaction and violence by the police
2020-05-29T17:24:24 < mawk> it was peaceful PaulFertser 
2020-05-29T17:24:26 < PaulFertser> mawk: I mean would the cops attack if it was really fully obviously non-violent?
2020-05-29T17:24:31 < mawk> but the police got orders to dislodge them
2020-05-29T17:24:41 < mawk> for the first iterations at least
2020-05-29T17:24:42 < Mangy_Dog> paul they dragged a 70 year old grand mother to the ground

2020-05-29T17:26:01 < mawk> for the first iterations of yellow vest it was fully non-violent
2020-05-29T17:26:12 < mawk> for the next iterations, radical left extremists got in, but they're very recognizable
2020-05-29T17:26:14 < mawk> "black bloc" style
2020-05-29T17:26:20 < mawk> the police can't miss who it is
2020-05-29T17:26:25 < mawk> but they shoot on everyone
2020-05-29T17:26:55 < PaulFertser> Did you just imply police should make assumptions based on appearance?
2020-05-29T17:27:11 < mawk> well they're breaking the law dressed like this 
2020-05-29T17:27:13 < mawk> so yes
2020-05-29T17:27:19 < mawk> you're not allowed to cover your face in france
2020-05-29T17:27:36 < mawk> they're all in black with hoodies and something in front of their faces
2020-05-29T17:28:43 < PaulFertser> I see. Sad to hear. So is there any country where the cops are really faithful?
2020-05-29T17:28:55 < mawk> well the cops hated doing this, supposedly
2020-05-29T17:28:57 < mawk> but it's the orders
2020-05-29T17:29:16 < mawk> macron's credibility was at stake, so his ministry of police tried to crush the protest at its inception
2020-05-29T17:29:40 < mawk> also paris' police chief is a very """tough""" guys that saw too many american army movies
2020-05-29T17:29:51 < mawk> so that plus that, the police gets harsh orders
2020-05-29T17:31:19 < PaulFertser> They're not ordered to shoot at people who do not violate the law, right.
2020-05-29T17:32:04 < mawk> well they passed a decree saying the protest is illegal
2020-05-29T17:32:07 < mawk> so they can shoot
2020-05-29T17:32:21 < PaulFertser> After it became violent?
2020-05-29T17:32:25 < PaulFertser> Or before?
2020-05-29T17:32:25 < mawk> protest is not in the constitution in france, you have to declare your protest then the chief of police has to approve it
2020-05-29T17:32:29 < mawk> before, probably
2020-05-29T17:32:34 < mawk> it all started as a facebook event 
2020-05-29T17:33:09 < mawk> but the law says they have to shoot in the torso, to be at good distance, to ask 3 times to disperse before they shoot, etc
2020-05-29T17:33:16 < mawk> and many videos show they don't do any of thazt
2020-05-29T17:33:28 < mawk> shoot in the face at a dozen meters distance with no advance warning
2020-05-29T17:33:42 < aandrew> heh "I approve this protest"
2020-05-29T17:33:49 < mawk> but when you try to sue them then the police of police say they cannot identify the cops on video, case closed
2020-05-29T17:33:51 < mawk> lol yeah
2020-05-29T17:34:02 < mawk> the same chief of police that gave the orders to be harsh on people has to approve the protest

2020-05-29T18:33:20 < zyp> ah, right
2020-05-29T18:33:22 < zyp> this is w25q
2020-05-29T18:33:36 < Thorn> well the command protocol is different between nor and nand

2020-05-29T18:36:45 < Thorn> hm that's not what I've seen in datasheets
2020-05-29T18:36:58 < zyp> well, this is NOR, they might have different footprints :)
2020-05-29T18:37:12 < Thorn> what I've seen has signals in the outer onion layer and all inner balls are NC
2020-05-29T18:37:25 < Thorn> oh ok I'm talking nand
2020-05-29T18:37:53 < zyp> my use is storing a fpga bitstream
2020-05-29T18:38:40 < zyp> and maybe some XIP firmware as well
2020-05-29T18:39:55 < zyp> but I mean, it's not like NC in center vs NC outer ring makes a big difference, either way it should be easy to route
2020-05-29T18:57:08 < zyp> as far as I can see, w25n pinout is identical to w25q
2020-05-29T18:58:17 < Thorn> does w25q have that 8x6mm wson-8 package?
2020-05-29T18:58:44 < Thorn> 4x2 pads on short sides + center pad
2020-05-29T18:58:48 < zyp> I think so
2020-05-29T18:59:18 < zyp> datasheet mentions 8x6mm wson-8, doesn't mention a center pad
2020-05-29T18:59:52 < zyp> ah, package details does
2020-05-29T18:59:53 < zyp> «The metal pad area on the bottom center of the package is not connected to any internal electrical signals. It can be left floating or connected to the device ground (GND pin).»

2020-05-29T19:09:25 < Thorn> where do you part numbers in altium disaster, which field?
2020-05-29T19:09:47 < zyp> Component Comment
2020-05-29T19:10:29 < Thorn> comment is what is displayed in the schematics, so with passive components you'd put a value there, not part#?
2020-05-29T19:10:44 < Steffanx> Gooday Thorn
2020-05-29T19:10:53 < Thorn> hi Steffanx 
2020-05-29T19:11:13 < zyp> for passives, the Comment is =Value, and then I have a user parameter named Value with the value
2020-05-29T19:11:25 < Thorn> yeah same
2020-05-29T19:11:31 < Thorn> but what about ICs
2020-05-29T19:11:43 < zyp> https://bin.jvnv.net/file/mj9iY.png
2020-05-29T19:12:22 < zyp> https://bin.jvnv.net/file/GG3NH.png
2020-05-29T19:15:50 < zyp> it's interesting how similar the command sets are between serial NOR and serial NAND
2020-05-29T19:15:51 < Thorn> okic. I'm trying to output a BOM as a spreadsheet and I found that I'd need a separate parameter for part # because passives aren't going to have a place to put one if you use comment for part #s
2020-05-29T19:16:30 < zyp> they both have the same read commands, the difference is that the NAND reads from a buffer while the NOR reads directly from the flash
2020-05-29T19:17:22 < zyp> do you use specific part numbers for passives?
2020-05-29T19:18:44 < zyp> my BOMs contain comment and footprint, so a typical resistor would be something like «10k, 0402»
2020-05-29T19:19:04 < Thorn> apparently manufacturer needs them
2020-05-29T19:19:28 < zyp> I generally don't care what brand of resistors the assemblyhouse is using

2020-05-29T19:20:30 < Laurenceb> sim code seems to be working ok now...
2020-05-29T19:21:02 < Laurenceb> so a win for back of the envelope: 60% floor area as collectors is about the point at which frosting stops
2020-05-29T19:21:19 < Laurenceb> but realistically just adding some barrels gives a ~9 mointh season
2020-05-29T19:21:22 < Laurenceb> *month
2020-05-29T19:24:04 < englishman> one 220L barrel per 2m^2 is pretty intrusive however
2020-05-29T19:24:24 < englishman> especially if it needs to be fully exposed to the sun, at 25deg above the horizon

2020-05-29T21:41:33 < Cracki> how much of that is it absorbing vs reflecting
2020-05-29T21:41:54 < Cracki> and would absorption cause it to radiate (half of) that into the volume
2020-05-29T21:48:51 < Laurenceb> yeah confusing

2020-05-29T21:49:13 < Laurenceb> heh everything englishman needs has been invented already (apart from using barrels as a thermal store)
2020-05-29T21:49:19 < Cracki> I'd bet on absorption
2020-05-29T21:49:22 < Laurenceb>  -> inflatable twin skin
2020-05-29T21:49:36 < Cracki> water for thermal storage is like stone for thermal storage

2020-05-29T22:43:13 < zyp> FT2232H and FT4232H are pinout compatible, but the pinouts are a bit inconvenient
2020-05-29T22:44:01 < zyp> ADBUS, ACBUS, BDBUS and BCBUS on the 2232 are respectivly ADBUS, BDBUS, CDBUS and DDBUS on the 4232
2020-05-29T22:44:34 < zyp> and only ADBUS/BDBUS on either are MPSSE capable
2020-05-29T22:46:03 < aandrew> FTDI detected
2020-05-29T22:47:00 < zyp> well, yeah, putting down one of these seems the clearly obvious answer to add usb-jtag for the fpga
2020-05-29T22:49:29 < zyp> considering going with the 4232
2020-05-29T22:50:00 < emeb> it's unfortunate that those are so ubiquitous in the jtag world
2020-05-29T22:50:38 < zyp> how so? seems like a convenient single chip solution that just works to me
2020-05-29T22:51:11 < emeb> there are many degrees of "just works"
2020-05-29T22:51:33 < emeb> just works as long as you have these huge cumbersome interface libraries 
2020-05-29T22:52:16 < zyp> which huge cumbersome interface libraries?
2020-05-29T22:52:28 < emeb> libftdi
2020-05-29T22:52:32 < zyp> isn't most stuff that matters libusb based?
2020-05-29T22:52:48 < emeb> hmm
2020-05-29T22:53:08 < emeb> what's the definition of "matters" here?
2020-05-29T22:53:56 < zyp> stuff that we'd actually want to use
2020-05-29T22:54:26 < zyp> and then some
2020-05-29T22:55:33 < emeb> maybe I've just got a chip on my shoulder because I've had FTDI jtag things fail on me mysteriously.
2020-05-29T22:59:09 < zyp> what other options are there though?
2020-05-29T23:00:10 < emeb> good question. I ended up just making my own with an F042
2020-05-29T23:01:00 < zyp> I could use a microcontroller, but then the question is what protocol? it's quickly resulting in having to make the host side tools as well
2020-05-29T23:01:11 < emeb> yes - that's the downside
2020-05-29T23:01:31 < emeb> otoh it's not that hard to do.
2020-05-29T23:01:33 < zyp> and that'd be slower, the ftdi parts are HS and can do 30 MHz jtag
2020-05-29T23:02:08 < emeb> but your protocol can be high level, rather than bitbanging
2020-05-29T23:02:49  * Laurenceb puts up a "covid secure" sign
2020-05-29T23:03:05 < Laurenceb> now everyone is safe
2020-05-29T23:03:20 < zyp> how much overhead are there really when loading a bitstream? I'd expect 30MHz jtag to be able to load the bitstream at close to 30 Mb/s
2020-05-29T23:03:29 < englishman> Laurenceb: currently looking like 10mm double wall plastic sheets
2020-05-29T23:03:43 < englishman> https://glashusen.se/produkt/tunnelvaxthus-fermer/
2020-05-29T23:03:50 < Laurenceb> interesting stuff
2020-05-29T23:06:34 < zyp> as far as I can see from one of my ECP5 .svf files, it's setting up a few small registers first, then it selects IR=0x7a and the rest is just a series of shift-DR commands
2020-05-29T23:07:19 < zyp> and then a few small regs at the end again
2020-05-29T23:08:07 < zyp> so FS USB would be a pretty big bottleneck compared to a HS-capable ftdi
2020-05-29T23:08:41 < englishman> Laurenceb: the stuff in your link is basically what we have now.
2020-05-29T23:08:46 < Laurenceb> ah cool
2020-05-29T23:08:56 < Laurenceb> that polycarbonate is v expensive per m^2
2020-05-29T23:09:12 < englishman> not if it's made in russia using cheap syrian oil.
2020-05-29T23:09:35 < Laurenceb> heh
2020-05-29T23:09:58 < englishman> i mean just look at the price at that sweedish link
2020-05-29T23:11:23 < zyp> hmm
2020-05-29T23:11:53 < zyp> there's not a major price difference between ft2232h and ft4232h, and they are in the same packages, so no size difference either
2020-05-29T23:12:03 < Laurenceb> englishman: I get about $100/m^2
2020-05-29T23:12:22 < Laurenceb> crazy pricey
2020-05-29T23:12:40 < zyp> apparently the disadvantages of the 4232 is that it can't do parallel interfaces, since each channel only has 8 pins
2020-05-29T23:13:05 < zyp> but I don't wanna spend that many fpga pins anyway, so whatever :)

2020-05-29T23:14:56 < englishman> and that's at a much larger scale
2020-05-29T23:15:03 < Laurenceb> ouch
2020-05-29T23:15:19 < Laurenceb> pe sheet is a fraction of that
2020-05-29T23:15:29 < englishman> yeah, but it doesn't last
2020-05-29T23:16:01 < englishman> you are required to heat it year round as well, as there's no snow load
2020-05-29T23:16:27 < englishman> rigid plastic is like 400kg/sqm
2020-05-29T23:16:54 < Laurenceb> that stuff thats uv stabilised lasts ten years
2020-05-29T23:17:18 < Laurenceb> but yeah I'm not sure how easily it will get busted by snow
2020-05-29T23:19:55 < Cracki> call someone up who has that setup?
2020-05-29T23:20:10 < Cracki> how hot does it have to be to melt x amount of snow per hour?
2020-05-29T23:20:13 < Cracki> etc
2020-05-29T23:20:22 < Laurenceb> yeah depends on the specifics of snow behaviour
2020-05-29T23:20:29 < Laurenceb> how often do you get sticking ice etc
2020-05-29T23:20:31 < Cracki> maybe they have some extr astrong tarps to throw on when snow/rain is expected
2020-05-29T23:20:34 < Laurenceb> yeah
2020-05-29T23:20:46 < Cracki> and I think snow would just slide down the 'surfaces' at enough angle
2020-05-29T23:20:49 < Laurenceb> or just spray it with antifreeze lol
2020-05-29T23:21:23 < Cracki> I'd be more worried about storms just blowing that flimsy stuff away
2020-05-29T23:21:54 < Laurenceb> nah its rated to very high wind speeds
2020-05-29T23:21:57 < Cracki> ic
2020-05-29T23:22:03 < Laurenceb> but snow loads can be more severe

2020-05-29T23:22:13 < Laurenceb> and chipping off ice is going to damage the surface
2020-05-29T23:22:22 < englishman> hmm, might be a good year to explore the tourist district of my town
2020-05-29T23:22:24 < Cracki> whack it from the inside instead?
2020-05-29T23:22:37 < englishman> Laurenceb: we get ice very often
2020-05-29T23:22:44 < englishman> 2-5 times
2020-05-29T23:22:56 < englishman> small unprotected trees always get trashed
2020-05-29T23:23:49 < Laurenceb> how thick is that polycarbonate?
2020-05-29T23:23:55 < englishman> 10mm
2020-05-29T23:24:58 < Cracki> 1mm walls, 8mm air inside, or something like that
2020-05-29T23:25:04 < Laurenceb> yeah
2020-05-29T23:25:18 < Cracki> good structure
2020-05-29T23:25:22 < Laurenceb> looks like it might be ~10% lower loss than double skin PE
2020-05-29T23:25:38 < Laurenceb> but 20% less light
2020-05-29T23:26:29 < Laurenceb> so about 8.5 months growing season rather than 9 for double PE unheated
2020-05-29T23:27:04 < Laurenceb>  - lower heat loss
2020-05-29T23:27:55 < Laurenceb> but at that price it makes sense to fit an external water heater, as the fractional cost increase is small

2020-05-29T23:46:53 < GenTooMan> I was looking into not using the HAL however, it appears ST has set up STM32CubeIDE to only use the HAL. I've looked through documentation but haven't found header files. I'm more worried about code bloat than speed however.

2020-05-30T00:04:33 < Cracki> GenTooMan, you can start with HAL code, dive into all the hal function definitions, realize they're only poking the same registers you can find in the reference manual, and then you can poke those registers yourself
2020-05-30T00:04:40 < Thorn> GenTooMan you're not forced to use HAL in any way. you can even make cube generate its init codes using LL
2020-05-30T00:04:45 < Cracki> HAL contains LL, which is more bare, and you can use that too
2020-05-30T00:04:57 < Cracki> and there are some recipes/blog posts on the net from people who do bare metal stm32

2020-05-30T00:05:21 < Thorn> and reference manuals are thankfully available
2020-05-30T00:06:10 < Cracki> I think the absolute minimum is just a C file with a main() doing nothing, _maybe_ a linker script or not
2020-05-30T00:06:41 < Cracki> https://vivonomicon.com/2018/04/02/bare-metal-stm32-programming-part-1-hello-arm/
2020-05-30T00:08:20 < Cracki> this was interesting too https://jacobmossberg.se/posts/2018/08/11/run-c-program-bare-metal-on-arm-cortex-m3.html
2020-05-30T00:08:45 < Cracki> you'll learn a lot of the low level goings on you might not learn from just using HAL
2020-05-30T00:09:07 < Cracki> you don't need to know assembler. the assembler you need can be copypasted
2020-05-30T00:16:16 < GenTooMan> assembler won't bother me. I guess I'll have to use HAL to get things working then worry about the LL a bit later.
2020-05-30T00:16:19 < GenTooMan> thanks
2020-05-30T00:16:24 < machinehum> GenTooMan: Last time I checked you could specify LL or hal
2020-05-30T00:16:42 < machinehum> idk if that's thing anymore
2020-05-30T00:19:22 < Cracki> some peripherals don't have LL code. I think that applies to stuff like USB.
2020-05-30T00:21:04 < Thorn> no need for assembly at all unless you're writing a preemptive scheduler
2020-05-30T00:21:28 < Thorn> this is cortex-m after all, the new era etc.
2020-05-30T00:22:18 < qyx> e-what?
2020-05-30T00:32:21 < GenTooMan> I've heard people declaring new era's enough to know that we lie to each other an awful lot. However use of assembler is far more reaching than just a preemptive  scheduler. Used judiciously it can make things work much cleaner faster or more compact. I seldom use assembler code any more but most C code does well enough. I do check what my code outputs however.

2020-05-30T02:25:34 < PaulFertser> GenTooMan: and of course with Rust you do not need that horrible HAL.
2020-05-30T02:28:07 < specing> or with Ada
2020-05-30T02:29:08 < Thorn> rust is the ultimate derailment tactics. it lets you play with the language instead of actually doing embedded stuff. ideal for EE-averse web developers

2020-05-30T02:29:38 < specing> I'm so sick of rust
2020-05-30T02:30:03 < specing> It just popped into existance and now everyone and their grandma program in rust (the same goes for golang)
2020-05-30T02:30:11 < specing> its just rust rust rust rust everywhere
2020-05-30T02:30:23 < PaulFertser> It might be the case Thorn, I often have a feeling most tasks solved by embedded developers do not require a high-level programming language.
2020-05-30T02:31:36 < Thorn> real engineering is never "high level"
2020-05-30T02:32:03 < PaulFertser> Depends on the kind of task at hand I'd say.
2020-05-30T02:33:42 < specing> PaulFertser: that's true
2020-05-30T02:33:52 < specing> But it can get messy without some abstractions
2020-05-30T02:47:44 < soreau> Where is 'upstream' for sketches and libraries downloadable in arduino ide?
2020-05-30T03:05:22 < Cracki> who uses "upstream" in what context
2020-05-30T03:05:43 < Cracki> ah you mean where are the packages, good q, best ask in #arduino or something like that

2020-05-30T03:08:44 < specing> the answer is probably github
2020-05-30T03:08:52 < specing> it's a monopoly
2020-05-30T03:08:55 < soreau> sure but what repo
2020-05-30T03:09:31 < soreau> is it rogerclarkmelbourne/Arduino_STM32 for all platforms?
2020-05-30T03:10:05 < Cracki> https://github.com/arduino/Arduino/wiki/Library-Manager-FAQ
2020-05-30T03:10:19 < Cracki> it says stm32, so NOT all platforms
2020-05-30T03:10:24 < Cracki> https://github.com/arduino/Arduino/wiki/Library-Manager-FAQ
2020-05-30T03:10:26 < Cracki> check that out
2020-05-30T03:11:25 < Cracki> basically, you open an issue on the official arduino github and someone adds a link to your stuff in their index
2020-05-30T03:12:42 < soreau> I guess the inverse question might be, is rogerclarkmelbourne/Arduino_STM32 used in arduino at all?
2020-05-30T03:16:50 < soreau> I'm trying to determine what steps would be required from installing arduino ide to building and using sketches in said repo, on windows and linux
2020-05-30T03:17:10 < Cracki> uh
2020-05-30T03:17:18 < Cracki> specifically for an stm32 target, or any arduino
2020-05-30T03:17:49 < soreau> I try to stay on topic, so I am referring to stm32 specifically 
2020-05-30T03:17:59 < Cracki> because obviously most arduinos aren't stm32, so that dude's repo will be useless to most arduino users
2020-05-30T03:18:03 < Cracki> is that clear so far
2020-05-30T03:18:09 < soreau> sure
2020-05-30T03:18:32 < Cracki> as for how to make use of his repo, there's a readme or it's in the wiki
2020-05-30T03:19:34 < Cracki> it likely involves adding some url to the "board manager" in arduino
2020-05-30T03:19:54 < Cracki> that or unpacking that repo in some directory in your arduino installation
2020-05-30T03:20:00 < Cracki> it's all in the wiki
2020-05-30T03:20:49 < soreau> I just don't remember doing the step of downloading master.zip and installing it, but maybe I did
2020-05-30T03:20:55 < Cracki> https://github.com/rogerclarkmelbourne/Arduino_STM32/wiki/Installation
2020-05-30T03:21:16 < Cracki> ST works on their own version of this. they use a boards manager url instead
2020-05-30T03:21:30 < Cracki> https://github.com/stm32duino/Arduino_Core_STM32
2020-05-30T03:22:25 < soreau> I wrote audio support so it's possible to use stm32f1 as a microphone
2020-05-30T03:22:38 < soreau> as composite device in conjunction with serial
2020-05-30T03:23:07 < soreau> the PR is here https://github.com/rogerclarkmelbourne/Arduino_STM32/pull/775
2020-05-30T03:24:50 < soreau> AFAIK, it's not possible to do audio as composite device with any other stm32 programming utility/libraries
2020-05-30T03:35:18 < Cracki> nice
2020-05-30T03:51:26 < soreau> I also wrote the speaker descriptors but there's no on board DAC so https://github.com/rogerclarkmelbourne/Arduino_STM32/pull/775/files#diff-f163c6d0f5661a9b8778760b2e7896bcR36
2020-05-30T03:55:45 < Cracki> very nice! there are F303CC boards around that have DACs. F4 boards exist too but dunno if they have dac
2020-05-30T03:56:17 < soreau> yea, I don't know everything :) This is my first time doing something like this
2020-05-30T03:56:26 < specing> soreau: stm32f072 has USB, DAC and ADC
2020-05-30T03:58:28 < soreau> but there was nothing using double buffered isochronous transfers so I ended up having to find these gems https://github.com/rogerclarkmelbourne/Arduino_STM32/pull/691/commits
2020-05-30T04:00:02 < soreau> otherwise, only every other data packet was sent
2020-05-30T04:05:26 < soreau> but also this was my first time developing something without printf (or equivalent) to push me along.. I guess my C skills are alright ;)

2020-05-30T15:48:44 < PaulFertser> Wearing masks is for protecting other people from coughing ill people. So if you're not ill, mask doesn't help much.
2020-05-30T15:48:46 < mawk> well I'm just coughing (or not really since I don't want to start coughing so I spray lidocaine in my throat)
2020-05-30T15:51:48 < Laurenceb> englishman: I simmed the polycarbonate https://ibin.co/5OIqryX7xlQh.png
2020-05-30T15:54:33 < englishman> lots of turquoise
2020-05-30T15:55:10 < englishman> not very far off but very consistent
2020-05-30T16:02:18 < antto> wut is this, loirens?
2020-05-30T16:07:50 < Laurenceb> antto: a totally not for growing cannabis greenhouse in Quebec
2020-05-30T16:08:12 < Laurenceb> englishman: yeah I expected it to be worse, turns out the IR properties of polycarbonate help a lot
2020-05-30T16:08:29 < antto> science-based w33d sh*t?
2020-05-30T16:08:46 < Laurenceb> also the greenhouse polycarbonate transmits a lot more light than the conservatory stuff we get in this country
2020-05-30T16:09:38 < Laurenceb> largest difference is during the day which is kind of good as you dont want it too hot

2020-05-30T16:21:20 < englishman> yes the barrels help to regulate that quite a bit too

2020-05-30T16:35:21 < Laurenceb> hmm there is method in the madness
2020-05-30T16:35:40 < Laurenceb> turns out there are so many dividers in the polycarbonate to break up convection cells
2020-05-30T16:36:02 < Laurenceb> so that reduces convective transfer by 20% or so
2020-05-30T16:36:32 < catphish> bought a new toy for mrs catphish https://i.imgur.com/v2zn3fF.jpg
2020-05-30T16:36:39 < Laurenceb> so 10mm polycarbonate has similar convective heat transfer to 100mm double skin polythene
2020-05-30T16:36:45 < Laurenceb> inb4 dildo
2020-05-30T16:37:18 < Laurenceb> catphish confirmed as boy racer
2020-05-30T16:37:55 < catphish> that car only comes with 2 engine options, 85hp or 180hp
2020-05-30T16:38:10 < Steffanx> No EV?!
2020-05-30T16:38:19 < catphish> not for the money i'm spending!
2020-05-30T16:38:34 < catphish> this is like a 10 year old car :)
2020-05-30T16:38:40 < Steffanx> Here cars like that are know as boy racer cars as well
2020-05-30T16:38:48 < Steffanx> Known*
2020-05-30T16:38:51 < englishman> there, they are known as lad racers
2020-05-30T16:38:55 < Laurenceb> kek
2020-05-30T16:39:15 < catphish> lol it's definitely a boy racer car
2020-05-30T16:39:24 < Laurenceb> looks like PC is actually better than polythene for thermal performance then
2020-05-30T16:39:31 < catphish> this one seems to have an aftermarket exhaust too, just in case it was too subtle before
2020-05-30T16:39:34 < Laurenceb> a little cooler during day, ~same at night
2020-05-30T16:39:42 < Laurenceb> so much fail catphish
2020-05-30T16:39:44 < Steffanx> The kind of car you cannot see the license plate of in your rear mirror because its so close to you
2020-05-30T16:39:58 < Laurenceb> you can get much better performance boost with engine remap
2020-05-30T16:40:33 < catphish> it's only a 1.4L4 already putting out 180hp!
2020-05-30T16:40:43 < Laurenceb> wow not bad
2020-05-30T16:41:00 < Laurenceb> turbo?
2020-05-30T16:41:08 < catphish> very much so
2020-05-30T16:41:30 < Steffanx> Nice "shopping cart" car
2020-05-30T16:41:35 < englishman> heh, the mk6 was already 10 years ago, time flies
2020-05-30T16:41:57 < catphish> i have a mk6 golf gti (2.0 turbo)
2020-05-30T16:42:14 < catphish> this is the polo, which is only 1.4 but somehow puts out nearly as much power, and much lighter
2020-05-30T16:43:04 < catphish> also, emma likes automatic, so this one is DSG :)
2020-05-30T16:43:08 < englishman> the 125 kW 1.4-litre TSI engine is a "Twincharger", and uses both a turbocharger and a supercharger.
2020-05-30T16:43:22 < catphish> even in 2010?
2020-05-30T16:43:29 < englishman> specifically that polo
2020-05-30T16:43:34 < catphish> oh cool!
2020-05-30T16:43:55 < englishman> 1.75bar from the supercharger
2020-05-30T16:43:58 < englishman> pretty hot for a gas motor
2020-05-30T16:44:19 < catphish> i suspect i will be borrowing it :)
2020-05-30T16:44:53 < catphish> paddle gears too, those are fun, never driven a DSG before
2020-05-30T16:45:26 < catphish> when i can buy a lightweight EV with this kind of performance, hopefully i will
2020-05-30T16:45:36 < englishman> roots style supercharger with magnetic clutch
2020-05-30T16:45:58 < englishman> when you put yourself in a model 3 performance you might forget all about why you care about lightweight
2020-05-30T16:46:11 < catphish> is the model 3 fast?
2020-05-30T16:46:16 < englishman> silly fast
2020-05-30T16:46:25 < catphish> (not that i want to spend that kind of money)
2020-05-30T16:46:47 < catphish> i will want to build my own EV soon
2020-05-30T16:48:04 < Steffanx> Lolol
2020-05-30T16:48:20 < Steffanx> Build a steam engine car first
2020-05-30T16:48:30 < englishman> 3.2 second 0-60 puts it around the audi S8, corvette z06, ferrari 458 quick
2020-05-30T16:49:13 < catphish> that must be a special model 3?
2020-05-30T16:49:25 < englishman> you just order it off the website
2020-05-30T16:49:30 < englishman> i wouldnt say it's special
2020-05-30T16:49:47 < catphish> there are multiple power levels available i mean?
2020-05-30T16:49:51 < englishman> yes
2020-05-30T16:49:54 < catphish> because the ones i've seen werent that fast
2020-05-30T16:50:02 < englishman> maybe press on the gas?
2020-05-30T16:50:06 < englishman> even the slowest one is pretty quick
2020-05-30T16:51:42 < catphish> i want a supercharged evora s, but thats probably too expensive too :)
2020-05-30T16:52:49 < englishman> hmm even the slowest tesla is a second faster 0-60 despite being 1250lb heavier
2020-05-30T16:52:55 < englishman> than the polo gti
2020-05-30T16:53:33 < catphish> lol i'm sure
2020-05-30T16:53:48 < catphish> shame its 10x the price :)
2020-05-30T16:54:05 < englishman> im sure in 10 years itll be the same
2020-05-30T16:54:28 < catphish> really someone needs to buy me this https://www.pistonheads.com/classifieds/used-cars/lotus/evora/lotus-evora-s-sports-racer-4-komotec-430-plus-upgrades-2013/10525933
2020-05-30T16:59:01 < catphish> looking forward to playing with the overpowered polo anyway :)

2020-05-30T18:05:14 < Steffanx> Daaamn
2020-05-30T18:05:44 < emeb> A bit early in the year for temps like that.

2020-05-30T18:06:21 < zyp> oh, hot here means like 20C
2020-05-30T18:06:23 < Steffanx> And I consider that hot
2020-05-30T18:06:44 < Steffanx> Yeah about the same here. 22C
2020-05-30T18:06:46 < emeb> Yes, but my idea of cold is much warmer than yours too.

2020-05-30T18:07:44 < emeb> Exactly. 
2020-05-30T18:09:15 < emeb> Homes here have some water pipes outside, uninsulated. If temps get < 0C then bad stuff happens.
2020-05-30T18:13:13 < englishman> it was 33C here yesterday quite pleasant. except for the 90% humidity
2020-05-30T18:13:55 < englishman> the nice thing about Arizona is you don't have to mow your rock lawn.
2020-05-30T18:14:15 < emeb> fact
2020-05-30T18:14:30 < emeb> but I do have to vacuum it.

2020-05-30T18:16:47 < zyp> you have to vacuum your «garden» or whatever you call it?
2020-05-30T18:17:02 < zyp> how does that work?

2020-05-30T18:17:59 < zyp> ah, for fallen leaves and shit?
2020-05-30T18:18:03 < emeb> yes
2020-05-30T18:18:06 < zyp> right
2020-05-30T18:18:32 < zyp> I were thinking dust and couldn't really imagine how
2020-05-30T18:18:41 < emeb> and desert plants in our landscaping are evergreen & drop leaves, flowers, seeds, etc throughout the year.
2020-05-30T18:19:42 < onio> Hi I am having problem with the I2C interrupt on STM32H750 running as a Master and talking to ADE7878A slave. When I run with interrupt priority "0", all is well, but if I run with priority "1" then I intermittently start seeing corruption with data and address
2020-05-30T18:20:04 < zyp> what other interrupts are you using?
2020-05-30T18:20:52 < onio> zyp, I have another I2C module acting as a slave to another device, I also have one SPI acting as a slave
2020-05-30T18:21:05 < zyp> consider that interrupt priorities only matters when you're using multiple interrupts, as it only defines which gets processed first
2020-05-30T18:24:28 < onio> I understand that but I would have expected one block the other if they are both the same priority but then the blocked one resumes after the first one finishes servicing it's ISR
2020-05-30T18:33:38 < zyp> if they are the same priority group, one handler will finish executing before the next can run
2020-05-30T18:33:55 < zyp> if they are different groups, a higher priority handler can preempt a lower priority one
2020-05-30T18:34:19 < zyp> so it could be you are having reentrancy issues when you assign different priorities
2020-05-30T18:36:23 < onio> zyp, that is correct. But what I don't expect is that even one interrupt preempts the other I don't expect the data to be corrupted.
2020-05-30T18:36:53 < zyp> are the handlers fully independent? no shared data?
2020-05-30T18:37:10 < onio> yes they are.
2020-05-30T18:37:14 < zyp> if so, it could be a race condition
2020-05-30T18:37:47 < zyp> e.g. you modify one register and then another, and usually it happens fast enough that it works, but if the handler gets preempted in the middle then something breaks
2020-05-30T18:38:30 < emeb> especially on ST's I2C - lots of SW intervention required and timing can be critical.
2020-05-30T18:38:56 < zyp> emeb, for v1, absolutely, but is v2 also that timing sensitive?
2020-05-30T18:39:12 < zyp> I actually still haven't used I2Cv2
2020-05-30T18:39:17 < emeb> zyp: perhaps not.
2020-05-30T18:39:26 < zyp> probably will soon
2020-05-30T18:39:34 < emeb> I use I2C on H7 but at a very high level w/ HAL.

2020-05-30T18:40:52 < zyp> I'm probably putting a G0 on this fpga board to negotiate PD, and it'll control the vreg over I2C
2020-05-30T18:41:16 < emeb> which families have v2?
2020-05-30T18:41:30 < zyp> everything from F3 on IIRC

2020-05-30T18:41:51 < emeb> Ah OK. Well then I've been using v2 a lot, for a long time. 
2020-05-30T18:41:59 < zyp> in other words, I think v1 is found in F1, F2, F4 and L1
2020-05-30T18:42:23 < onio> zyp, emeb thanks, I would keep digging to see if I can make sense of what is causing it to go wrong
2020-05-30T18:44:00 < zyp> emeb, I've been pretty successful in avoiding it so far :)
2020-05-30T18:44:26 < emeb> heh
2020-05-30T18:44:43 < emeb> I've done a lot of F3, F7 & H7 stuff over the last few years
2020-05-30T18:45:35 < zyp> I mean i2c, I don't think I've designed a board with i2c devices on it since the quadrotor controller way back
2020-05-30T18:46:10 < emeb> yeah. I usually have I2C for controlling codecs or OLEDs.
2020-05-30T18:46:28 < zyp> I used spi last I played with an OLED
2020-05-30T18:46:38 < zyp> but yeah
2020-05-30T18:46:48 < zyp> fpga board will have a bunch of i2c devices
2020-05-30T18:47:05 < emeb> also for EEPROMs - most of my client work needs some nonvolatile storage.
2020-05-30T18:47:20 < zyp> vreg, clock synth, crosspoint switch for the serdes lanes, SPD eeprom on the sodimm, etc…
2020-05-30T18:47:35 < emeb> and since it can change frequently I don't like futzing w/ EEPROM emulation in flash.
2020-05-30T18:47:41 < zyp> true
2020-05-30T18:48:21 < emeb> it's for UI state, which can change several times / minute as users tweak settings etc.
2020-05-30T18:48:42 < zyp> although the eeprom emulation stuff I've got in workstuff is fairly elegant
2020-05-30T18:49:06 < emeb> sure - if you do wear leveling & journaling it can be fine.
2020-05-30T18:49:25 -!- funnel [~funnel@unaffiliated/espiral] has joined ##stm32
2020-05-30T18:49:27 < emeb> but H7 flash sectors are 128kB and well, don't need that much.
2020-05-30T18:49:43 < zyp> I'm using two flash pages, organized as arrays of 64-bit records
2020-05-30T18:50:09 < zyp> each record has a 16-bit key, a 32-bit value and some reserved space for metadata
2020-05-30T18:50:25 < emeb> nice
2020-05-30T18:50:44 < zyp> every time a value is changed, I just append a new record to the active page
2020-05-30T18:51:09 < zyp> when I look up values, I scan the active page backwards from the end
2020-05-30T18:51:25 < emeb> yep - that's what I've seen too. Then when you get to the end of the allocated sectors you erase and start over
2020-05-30T18:51:49 < zyp> and when the active page is full, I defragment it by copying the most recent values for each key to the other page and erase
2020-05-30T18:52:21 < emeb> how many keys do you have?
2020-05-30T18:53:06 < Cracki> eeprom emulation :D
2020-05-30T18:53:23 < zyp> not sure
2020-05-30T18:53:51 < Cracki> ST has some code, had to rewrite it pretty much because they made moronic assumptions... also a corner case could kill your data (reset at the right moment)
2020-05-30T18:54:04 < emeb> ugh
2020-05-30T18:54:18 < Cracki> very implausible that you'd hit that case tho
2020-05-30T18:54:34 < zyp> Cracki, that's why I have two pages
2020-05-30T18:54:41 < Cracki> they do too
2020-05-30T18:54:53 < Cracki> but they mixed up some sequence of events
2020-05-30T18:54:58 < zyp> fun
2020-05-30T18:55:28 < zyp> emeb, IIRC my pages are 16k, so they can fit 2k records
2020-05-30T18:56:06 < Cracki> which reminds me, I need to add a generation count to my pages/sections
2020-05-30T18:56:16 < zyp> at the moment I haven't started using it yet for the control algo stuff that my coworker has, where most of the variables are
2020-05-30T18:56:34 < zyp> so I think at the moment I've got like two keys :)
2020-05-30T18:56:43 < emeb> heh - just testing
2020-05-30T18:56:44 < zyp> bus address and encoder offset
2020-05-30T18:56:48 < Cracki> I'll need a string area too... that'll be fun
2020-05-30T18:57:34 < zyp> a bonus feature of doing it this way is that I get an edit log I can look up as well, if I need to revert to an earlier value
2020-05-30T18:58:00 < Cracki> ye one has to dimension the pages such that they aren't full right after a transfer/copy, that there's enough space to write some changes before another copy-erase cycle is needed
2020-05-30T18:59:14 < emeb> a trail of breadcrumbs
2020-05-30T19:00:00 < zyp> I guess another way to do it could be to use protobuf
2020-05-30T19:00:44 < zyp> IIRC you can concatenate protobufs where duplicates of a field would overwrite the previous
2020-05-30T19:01:22 < zyp> but in my case I'm limited to 64-bit writes due to ECC
2020-05-30T19:03:48 < Cracki> hm, you're forced to use 64 bit writes, and the 16 spare bits... could signify the type of a variant perhaps
2020-05-30T19:04:25 < Cracki> for now I'm storing single floats only but labeling things as bool/int/bitvector could be convenient
2020-05-30T19:04:33 < zyp> yes, that's what I have in mind
2020-05-30T19:04:46 < Cracki> otoh that's dynamic typing. I need the type to be fixed per "key" anyway
2020-05-30T19:05:07 < Cracki> so what I'll need is a big table that assigns names to the keys (and types too), and that's static
2020-05-30T19:05:27 < zyp> I'm storing u8/u16/u32/s8/s16/s32/f32, but it's all up to the code to ask for the right type when loading it
2020-05-30T19:05:31 < Cracki> I once did that with some preprocessor mess
2020-05-30T19:05:51 < zyp> but I'm thinking about adding a type field so I can sanity check that
2020-05-30T19:06:06 < Cracki> that would also take care of the type because I'd ask for the value by name, and the preprocessor stuff would take the right type info from that table I have
2020-05-30T19:06:49 < Cracki> I think I had to go as far as actually implementing a variant type for this to work at runtime
2020-05-30T19:07:14 < Cracki> (i.e. asking for any variable by string name, and then the code would have to handle any type it turns out to be)
2020-05-30T19:09:07 < Thorn> why is there an armored truck with a machine gun on it in the convoy?
2020-05-30T19:09:20 < Cracki> why not
2020-05-30T19:09:31 < zyp> 'MURICA
2020-05-30T19:09:35 < Cracki> they're preparing for rioters
2020-05-30T19:09:53 < Cracki> blast them off the road if they try to take those big plasma tvs inside the cars and the capsule
2020-05-30T19:10:03 < Thorn> I've never heard of anything like that on Baikonur
2020-05-30T19:10:12 < Cracki> because russia is a high trust society
2020-05-30T19:10:15 < zyp> is this live now, not just a recap from the other day?

2020-05-30T19:12:23 < Cracki> ahem, do you deny russia's claim
2020-05-30T19:12:35 < zyp> next you're gonna tell me Kazakhstan is not in Russia
2020-05-30T19:12:37 < PaulFertser> Russia never claimed Baikonur belongs there.

2020-05-30T19:13:12 < Cracki> was  Kazakhstan not part of the soviet union?

2020-05-30T20:30:39 < Cracki> assuming you have clear blue sky and sun
2020-05-30T20:30:41 < BrainDamage> come with everything needed
2020-05-30T20:30:54 < BrainDamage> the sun's output is highly variable

2020-05-30T20:32:36 < Cracki> you are a very patient man
2020-05-30T20:33:05 < bitmask> no point in wasting film and pcb calibrating for the sun when im just gonna change it up in a few days

2020-05-30T20:33:12 < bitmask> heh yea
2020-05-30T20:33:46 < bitmask> since i have the transparencies I can work on my calibration print
2020-05-30T20:37:01 < Laurenceb> englishman: I tried adding a basic thermal shock model to my simcode, basically assuming 1.6mm inner liner glass inside the tubes (the thermal mass) and max 175C->~50C temperature swing (from the datasheets for the chinese tubes)
2020-05-30T20:37:32 < Laurenceb> turns out it is a risk a few times a year, so a thermocouple inside the tubes with thermal cutoff controller is prob needed
2020-05-30T20:37:46 < Laurenceb> but that has ~0 impact on panel output
2020-05-30T20:38:17 < Laurenceb> I want to try this in uk now, for home heating
2020-05-30T20:39:18 < Laurenceb> according to https://forum.heatinghelp.com/ you can crack vacuum tube heaters with thermal shock even if they have heat pipes fitted O_o
2020-05-30T20:39:52 < BrainDamage> just keep water circulating and you'll have no thermal shock
2020-05-30T20:41:01 < BrainDamage> you can even circulate to a heatsink if you want

2020-05-30T20:42:59 < Laurenceb> would be cool to make something that could integrate with a typical uk central heating system, but I cant quite see it working :S
2020-05-30T20:43:15 < Laurenceb> maybe with my house as it has plastic pipework

2020-05-30T22:31:06 < Mangy_Dog> i think it peaked at 2.6g

2020-05-30T22:37:03 < R2COM> catphish that suspect has in his history robbery where he entered house and put gun to a belly of pregnant woman. OK? so anyone who questions that cop can go fuck himself
2020-05-30T22:37:13 < catphish> "someone who was robbing a pregnant woman in my understanding has no human rights attached to him" << if you actually believe that, i don't think there's any point in us discussing this further
2020-05-30T22:37:19 < R2COM> and no you wont level any complaint in china, you can only talk shit here
2020-05-30T22:38:05 < catphish> i don't understand, i would never visit either of those countries, obviously i'm only going to complain from a safe distance

2020-05-30T22:46:25 < Cracki> I like him
2020-05-30T22:46:47 < catphish> i think that went a bit further than i enjoy from a spirited debate
2020-05-30T22:48:13 < Steffanx> I had the right to kick him, he was mean to me in the past. Like on day 1 we met in #sparkfun 
2020-05-30T22:48:19 < mawk> lol
2020-05-30T22:48:22 < zyp> haha
2020-05-30T22:48:57 < catphish> putting aside the numerous strawmen, i think wishing assult with a deadly weapon on people you disagree with is a  bit much
2020-05-30T22:49:33 < Steffanx> whatever, not even going to discuss any of this. Because yankeeland.
2020-05-30T22:50:14 < mawk> we should nuke the usa
2020-05-30T22:50:16 < catphish> i don't know yankeeland, but they do seem to have oddly extreme political positions
2020-05-30T22:50:21 < mawk> wouldn't that solve a whole bunch of problems ?
2020-05-30T22:50:50 < mawk> end dollar hegemony, end oil wars, end various embargos, and that would clear up a massive piece of land to send all our prisoners
2020-05-30T22:50:57 < mawk> making some room for the good people on the continent
2020-05-30T22:51:22 < Cracki> he has a sense of self preservation in things that matter (life) but not in things that don't matter (being in an irc channel). some people are the opposite, try to play by the rules but would just get themselves killed IRL
2020-05-30T22:52:32 < catphish> some people actually have an array of opinions that don't fit a specific mould
2020-05-30T22:52:53 < zyp> to me, his point seems to boil down to «it's okay to kill criminals»
2020-05-30T22:53:02 < mawk> yeah that point was weird
2020-05-30T22:53:14 < Steffanx> Kill strata, kill him now!
2020-05-30T22:53:18 < catphish> zyp: he said as much flat out
2020-05-30T22:53:21 < mawk> ok they have death penalty, but everyone should have a fair trial
2020-05-30T22:53:27 < Cracki> death penalty is foreign to most westerners today
2020-05-30T22:53:36 < Cracki> it was quite common not too long ago
2020-05-30T22:53:49 < catphish> zyp: but what offended me more was "if you don't want to kill criminals, you'd defend them in court"
2020-05-30T22:53:50 < zyp> well, the reasoning behind it is easy enough to understand, it's just that killing criminals doesn't seem to do all that much to deter crime
2020-05-30T22:54:14 < Steffanx> Anyway, do you really want to discuss this without him being here? ;)
2020-05-30T22:54:14 < catphish> like, can't we have some middle ground where they get punished or (crazy thought) rehabilitated?
2020-05-30T22:54:36 < zyp> I feel like a lot of people get too hung up on punishing criminals, the point should be reducing crime
2020-05-30T22:54:47 < catphish> well i'm mostly just bashing him and his strawman, it's more fun than not, but should probably get back on topic
2020-05-30T22:54:56 < catphish> i'm angry because i wanted to talk to him about motors
2020-05-30T22:55:03 < Steffanx> lol
2020-05-30T22:55:22 < zyp> Steffanx, yeah, now there's actually room for other viewpoints than just his
2020-05-30T22:56:37 < mawk> zyp: at least killing criminals will deter future crime for that same criminal
2020-05-30T22:56:54 < mawk> and I can't see how it would encourage crime, it should at least at a minimum deter it for others
2020-05-30T22:56:56 < mawk> net gain
2020-05-30T22:56:56 < Cracki> :D
2020-05-30T22:56:56 < catphish>  technically the truth
2020-05-30T22:57:10 < catphish> we could just kill everyone, then there'd be no crime at all
2020-05-30T22:57:20 < mawk> but the loss in case of judicial error is infinite, aka killing an innocent
2020-05-30T22:57:27 < mawk> and the probability of judicial error is non-zero
2020-05-30T22:57:28 < Cracki> sure, try your rehabilitation, but if it fails, death penalty is cheaper than incarceration
2020-05-30T22:57:32 < mawk> so that's why I don't really like death penalty
2020-05-30T22:57:46 < zyp> Cracki, source?
2020-05-30T22:58:08 < zyp> Cracki, my impression was that death penalty is more expensice than life incarceration
2020-05-30T22:58:19 < Cracki> impression
2020-05-30T22:58:24 < mawk> it's the cost of a vial of phenobarbital and a bag of potassium chlorure
2020-05-30T22:58:28 < Cracki> ^
2020-05-30T22:58:34 < mawk> but yeah with death penalty you stay in the "row" for very long
2020-05-30T22:58:35 < Cracki> I'm looking
2020-05-30T22:58:38 < mawk> so that's not cheap
2020-05-30T22:58:41 < catphish> so what's wrong with killing an innocent person? and why don't those same things apply to killing someone who has committed a crime?
2020-05-30T22:59:09 < Cracki> I'll not count cost for court time, just incarceration vs execution
2020-05-30T22:59:18 < catphish> i favour killing all humans, it solved the problem completely, anyone might commit a serious crime in the future, we can't accurately identify them, even by their previous crimes
2020-05-30T22:59:20 < Cracki> uh, an innocent person is innocent
2020-05-30T22:59:20 < mawk> maybe it is wrong catphish , but then you need to know if this wrongness is more than the good reasons to suppress a criminal
2020-05-30T22:59:36 < Cracki> now you're strawmanning catphish
2020-05-30T23:00:10 < catphish> no, i'm presenting a silly argument of my own, that's not quite the same
2020-05-30T23:00:27 < Cracki> we have several issues here. (1) existence of death penalty (2) how serious a crime has to be to warrant it (3) when to give up rehabilitation
2020-05-30T23:00:32 < catphish> but probably equally invalid as an argument, i'm just trying to lighten the mood while making a serious point
2020-05-30T23:00:36 < Cracki> it's still a strawman
2020-05-30T23:00:43 < Cracki> that or arguing in bad faith
2020-05-30T23:00:52 < catphish> i suppose attacking your own silly argument is just as bad
2020-05-30T23:01:03 < Cracki> you have gained nothing really
2020-05-30T23:01:04 < catphish> since you're essntially attributing it to someone else
2020-05-30T23:02:10 < catphish> Cracki: anyway, those are obviously the questions, fortunately most countries are able to afford to permanently incarcerate the most dangerous without killing them, which i generally prefer
2020-05-30T23:02:23 < Cracki> it's a strain on your tax payers
2020-05-30T23:02:28 < catphish> no doubt
2020-05-30T23:02:32 < Cracki> so the tax payers should decide
2020-05-30T23:02:43 < catphish> well they do
2020-05-30T23:02:48 < catphish> that's kinda how democracy works
2020-05-30T23:03:07 < Cracki> except they get told what to vote for OR ELSE THEY'RE EVIL RIGHT WINGERS
2020-05-30T23:03:16 < Cracki> that's kinda how democracy works
2020-05-30T23:03:23 < catphish> it's interesting how people vote for what they're told to though :(
2020-05-30T23:03:38 < Cracki> :( is right
2020-05-30T23:03:40 < Cracki> it's sad
2020-05-30T23:03:44 < catphish> yeah, i do dislike FPTP democracy, not much room for individual views
2020-05-30T23:04:18 < zyp> Cracki, why would you not count the cost for court time when it's not equal?
2020-05-30T23:04:45 < catphish> zyp: presumably that depends totally how much you spend on those things
2020-05-30T23:04:54 < zyp> surely if you're making a point about the cost, it's the total cost that matters
2020-05-30T23:05:23 < zyp> catphish, thing is, death penalty tend to require way more complex court cases
2020-05-30T23:05:33 < catphish> as it should i suppsoe
2020-05-30T23:05:36 < zyp> yes
2020-05-30T23:06:04 < Cracki> murican prisons are a commercialized enterprise. inmates are sold to the lowest bidder
2020-05-30T23:06:24 < zyp> that's fucked up too
2020-05-30T23:06:39 < Cracki> so if you actually had humane prisons, the cost of life inprisonment would skyrocket
2020-05-30T23:06:47 < catphish> our taxpayers here pay quite a lot of tax, but we do have reasonably good public services
2020-05-30T23:06:57 < Cracki> now you have inhumane prisons, so a life sentence is arguably worse than just ending it
2020-05-30T23:07:03 < catphish> no idea how nice our prisons are, never been in one
2020-05-30T23:07:07 < zyp> when prisons are profiting off criminals, why would they put effort into rehabilitating them from committing more crime?
2020-05-30T23:07:17 < catphish> what zyp said
2020-05-30T23:07:29 < Cracki> there are prison tours. school classes can get that, I'm sure individual adults can too
2020-05-30T23:07:48 < catphish> of course, if US of A put less people in prison for silly drugs things, they could spend more money making them less shitty
2020-05-30T23:08:08 < Cracki> just shoot the drug dealers
2020-05-30T23:08:16 < catphish> why waste bullets
2020-05-30T23:08:17 < Cracki> drug addicts get help, dealers get ended
2020-05-30T23:08:21 < catphish> just crush them in the street
2020-05-30T23:08:23 < Cracki> kneel on them?
2020-05-30T23:08:41 < jadew`> what's the topic? why would you want prison to be less shitty?
2020-05-30T23:08:49 < jadew`> it's supposed to a bad experience
2020-05-30T23:08:50 < Steffanx> Stopping drugs dealing is .. an utopia.
2020-05-30T23:08:54 < catphish> sadly life isn't that simple, most drug dealers are users whose friends want drugs and they share them out to help pay the costs
2020-05-30T23:09:12 < Cracki> just hand the drug business to a fine upstanding family like the sacklers
2020-05-30T23:09:13 < catphish> jadew`: fsvo bad sure
2020-05-30T23:09:27 < Cracki> I'd question the "most"
2020-05-30T23:09:28 < zyp> I've never been in a prison here either, but my understanding is that norway got some of the most humane prisons in the world
2020-05-30T23:09:36 < Cracki> drugs are a business. criminals use it to make money.
2020-05-30T23:09:59 < Cracki> if you're on drugs, I highly doubt you're in the "state of mind" for organized crime
2020-05-30T23:10:21 < Cracki> norway doesn't have the societal problems the US has
2020-05-30T23:10:23 < catphish> Cracki: yeah, that's not true sadly
2020-05-30T23:10:28 < zyp> and I'm pretty comfortable with the fact that my taxes are contributing to keeping shitheads like Anders Behring Breivik and Philip Manshaus in them
2020-05-30T23:10:42 < zyp> Cracki, cause and effect
2020-05-30T23:10:44 < Cracki> nobody argues for releasing those people
2020-05-30T23:11:00 < catphish> Cracki: most drug users can understand the simple concept of bulk discount and selling to their friends
2020-05-30T23:11:06 < Cracki> didn't murica recently release prisoners because reasons?
2020-05-30T23:11:19 < Cracki> and several of them just went and hurt or killed people
2020-05-30T23:11:32 < Cracki> catphish, that's very low level dealing
2020-05-30T23:11:36 < catphish> Cracki: sounds plausible :( not sure i read about that
2020-05-30T23:11:46 < zyp> Cracki, the way I see it, if you treat your population like assholes, you get a population of assholes
2020-05-30T23:11:51 < Cracki> *g*
2020-05-30T23:11:53 < catphish> Cracki: well sure, of course, but USA (from what i've heard) is very harsh on them
2020-05-30T23:12:15 < zyp> treat your population like people, maybe you'll find out they are actually people
2020-05-30T23:12:23 < catphish> like, mandetory prison for *any* dealing
2020-05-30T23:12:29 < Cracki> "bulk discount" is the flip side of "let me parcel that up and cut it with baking soda"
2020-05-30T23:13:07 < jadew`> zyp, yeah, those people who also treat you like people
2020-05-30T23:13:11 < Cracki> I wish that we all could have a little toy city/state/country where we could try out these approaches
2020-05-30T23:13:21 < zyp> jadew`, somebody have to go first
2020-05-30T23:13:23 < Cracki> you'd learn so much about the nature of different humans
2020-05-30T23:13:32 < jadew`> zyp, somebody already did
2020-05-30T23:13:45 < jadew`> they make a choice to consider you an object and steal/hurt you
2020-05-30T23:13:59 < jadew`> if you treat them better than they are treating you, that's a weakness
2020-05-30T23:14:06 < jadew`> not a virtue
2020-05-30T23:14:24 < jadew`> and it's only going to lead them into thinking that it's ok to exploit it
2020-05-30T23:15:04 < zyp> if everybody would treat everyone else no better than they are treated themselves, you'd just get a downward spiral
2020-05-30T23:15:41 < jadew`> not saying that you should never give a little
2020-05-30T23:15:47 < jadew`> but tolerance without limits is wrong
2020-05-30T23:16:02 < zyp> that's why we have laws
2020-05-30T23:16:13 < jadew`> some people deserve to be treated like scum (and they might actually need it, in order to be forced into becoming normal members of society)
2020-05-30T23:16:47 < jadew`> punishment that isn't actually punishment is absolutely pointless
2020-05-30T23:17:01 < catphish> i'm super happy with my door lock / IP stack
2020-05-30T23:17:11 < zyp> catphish, nice
2020-05-30T23:17:12 < catphish> seems stable / effective
2020-05-30T23:17:51 < catphish> now i just have to get someone to make a nice web ui for it
2020-05-30T23:18:12 < catphish> but my web ui guy says if he does that he won't do [actual work we get paid for] :(
2020-05-30T23:18:20 < Cracki> you know, game theory has a notion of time. you can give strangers some positive credit, but if they abuse it, you can absolutely finish them
2020-05-30T23:18:37 < Cracki> you don't have to always be more lenient, or always stricter
2020-05-30T23:19:01 < zyp> game theory also has tragedy of the commons
2020-05-30T23:19:20 < Cracki> minneapolis is a "commons" right now
2020-05-30T23:19:33 < Cracki> there are pictures going around showing who is doing the cleanup rn
2020-05-30T23:19:44 < Cracki> not the same people that trashed it
2020-05-30T23:19:53 < Cracki> it's like shift work
2020-05-30T23:20:19 < Cracki> nice web ui you say, I think I know someone
2020-05-30T23:20:30 < Cracki> strata, dude needs a web ui :D
2020-05-30T23:23:08 < Cracki> oh, found something https://fedsoc.org/commentary/publications/the-next-time-someone-says-the-death-penalty-costs-more-than-life-in-prison-show-them-this-article
2020-05-30T23:23:49 -!- kakimir [b23796d3@178-55-150-211.bb.dnainternet.fi] has joined ##stm32
2020-05-30T23:24:16 < Cracki> comparing lowest bidder prisons to bureaucratic waste
2020-05-30T23:26:00 < Laurenceb> >life in prison in usa
2020-05-30T23:26:02 < Laurenceb> >costing
2020-05-30T23:26:05 < jadew`> I don't think the argument for the death penalty was ever about money tho
2020-05-30T23:26:09 < Laurenceb> isnt it liek slave labour
2020-05-30T23:26:17 < jadew`> it's always about offering retribution to the victims
2020-05-30T23:27:09 < friendofafriend> That article amounts to "the death penalty is expensive because people oppose it"?
2020-05-30T23:28:07 < friendofafriend> That's uncomfortable footing on which to support the death penalty.
2020-05-30T23:29:11 < Cracki> you missed the part where people overwhelmingly voted to remove the bureaucratic waste
2020-05-30T23:29:44 < kakimir> hwello Lurencer
2020-05-30T23:29:49 < kakimir> is musk in space yet?
2020-05-30T23:30:21 < kakimir> I just opened some stream where guys sit on their monitoring desks
2020-05-30T23:30:23 < Cracki> his car is
2020-05-30T23:30:35 < Cracki> the two astronauts have arrived safely in space
2020-05-30T23:30:47 < kakimir> they cannot stream it because law?
2020-05-30T23:30:50 < Cracki> they're now chilling and sleeping until they're near the station
2020-05-30T23:30:54 < Cracki> no clue
2020-05-30T23:31:23 < Cracki> the whole launch was streamed, except the time between 1st stage shaking the ship and 1st stage standing on deck
2020-05-30T23:31:25 < Laurenceb> I think they have having homosex
2020-05-30T23:31:34 < Cracki> zero gay
2020-05-30T23:31:36 < kakimir> :D
2020-05-30T23:31:39 < Laurenceb> they turned off the camera for "privacy"
2020-05-30T23:31:59 < kakimir> I think lurencer can be funny
2020-05-30T23:32:10 < kakimir> there is hints of funny in what he says
2020-05-30T23:35:30 < friendofafriend> Cracki: It's a strange article.  Noting expert witnesses cost $6k to appear in '97, on a high profile case, doesn't even make my teeth ache a little.
2020-05-30T23:36:15 < Cracki> that's a tiny fraction of the cost, why do you focus on that
2020-05-30T23:36:38 < friendofafriend> Only because the article noted it as an example of cost.
2020-05-30T23:37:00 < kakimir> what are you up to now lurencer?
2020-05-30T23:37:12 < friendofafriend> I guess the question is why did the article focus on it.  I had the same reaction as you.
2020-05-30T23:38:08 < Steffanx> Whoa the kakimir is alive
2020-05-30T23:38:25 < kakimir> steff got so worried
2020-05-30T23:39:02 < friendofafriend> To think a court would ever grant the State a continuance over the State's budget concerns is potent, if you consider their reaction to you asking the same courtesy.
2020-05-30T23:39:55 < zyp> «Evidence suggests that if the death penalty were abolished, death-penalty opponents would next claim that life without arole is cruel and unusual punishment, and demand parole eligibility for murderers!»
2020-05-30T23:40:00 < zyp> nice slippery slope argument
2020-05-30T23:40:32 < friendofafriend> You could reverse, and say life is more cruel than death.
2020-05-30T23:41:10 < jadew`> that's for the victims to decide
2020-05-30T23:41:20 < jadew`> I'm sure many would disagree
2020-05-30T23:41:28 < friendofafriend> They can't even decide to prosecute or not, so lolno.
2020-05-30T23:41:52 < friendofafriend> It's the State pressing the charges, you don't have standing.
2020-05-30T23:42:10 < jadew`> yes, but taking the ultimate punishment away, would take it away from those who think this way
2020-05-30T23:42:32 < jadew`> (the victims)
2020-05-30T23:42:42 < friendofafriend> Whatever the ultimate punishment was meant to curtail, it didn't -- you still have the ultimate punishment going on.
2020-05-30T23:43:07 < friendofafriend> Crime isn't much a thinking man's game, anyway.
2020-05-30T23:46:29 < friendofafriend> You'd also have to be a special kind to think appeals aren't already lopsided toward the State, as the original ruling is "seen in the best possible light" by the appeals court when assessing error.
2020-05-30T23:47:39 < friendofafriend> That it's "too expensive" should more concern you about the private party trying to defend themselves.  Certainly they don't have the State's legal budget to keep themselves uncaged.
2020-05-30T23:50:00 < Cracki> lawfare
2020-05-30T23:51:02 < friendofafriend> Absolutely, lawfare.  It just got me confused, because the body of the article just seemed so unaligned with the conclusion.  Give 'em more budget, or fast track in favor of the State.
2020-05-30T23:51:56 < friendofafriend> And that's noodly, try them for something less that'll stick and see them in for a certain decade.  A canned decade is not light.
2020-05-30T23:52:50 < friendofafriend> The elements between manslaughter and murder are mental.  The difference between degrees of murder is mental.
2020-05-30T23:53:35 < friendofafriend> (And you can make manslaughter stick to a greased Teflon pan.)
2020-05-30T23:55:14 < friendofafriend> It's like the prosecuting attorney is a kid.  You take 'em to the buffet, and they tell you they want a plate of frosting.  They want it high profile, 'cause muh Facebook.
2020-05-30T23:56:41 < friendofafriend> Eye-opening read.  Thanks again, Cracki.

2020-05-31T01:03:25 < zyp> wtf do I call a usb port that's used for a FT4232H that's hooked to both jtag and some uarts? jtag/debug/console/whatever only seems to name half the functionality of the port
2020-05-31T01:04:47 < englishman> nice job steffanx
2020-05-31T01:05:02 < qyx> I would call it debug
2020-05-31T01:05:13 < englishman> but can you kill the rest of the cancer killing stm32
2020-05-31T01:05:14 < qyx> because it is a debug jtag and debug serial console
2020-05-31T01:05:54 < Steffanx> Englishman... feel free to do so?
2020-05-31T01:06:38 < zyp> qyx, yeah, except the uarts might be used for more than just debug
2020-05-31T01:07:03 < englishman> Steffanx: I talked someone out of using pic yesterday.
2020-05-31T01:07:07 < zyp> but yeah, let's go with that and not bikeshed this more
2020-05-31T01:07:33 < englishman> multifunction port
2020-05-31T01:08:18 < zyp> next question, I have two more usb ports, that will be connected to an ULPI transceiver each for generic use by the FPGA
2020-05-31T01:08:20 < qyx> https://i.imgur.com/VS3lVCB.png
2020-05-31T01:08:28 < qyx> any reason for that pullDOWN?
2020-05-31T01:08:45 < qyx> USB1 and USB2
2020-05-31T01:09:01 < qyx> englishman: are you using adaptive data rate?
2020-05-31T01:09:01 < zyp> would it be confusing to name them USB_A and USB_B in the schematic, despite A/B having nothing to do with the connector type? (they are both USB-C)
2020-05-31T01:09:08 < qyx> yes
2020-05-31T01:09:20 < qyx> I hate that on sama5d27
2020-05-31T01:09:26 < qyx> there are usb-a, usb-b and usb-c
2020-05-31T01:09:28 < englishman> qyx: good question. I don't know. it worked out of the box.
2020-05-31T01:09:33 < qyx> usb-b is USB-A
2020-05-31T01:09:39 < qyx> usb-a is OTG
2020-05-31T01:09:41 < qyx> or so
2020-05-31T01:09:47 < zyp> haha
2020-05-31T01:09:59 < zyp> so USB_0 and USB_1 would be better?
2020-05-31T01:10:07 < englishman> would it be confusing to call them usb1 and usb 2 when they are both usb2
2020-05-31T01:10:13 < qyx> lol
2020-05-31T01:10:30 < zyp> englishman, usb3 actually :)
2020-05-31T01:10:37 < zyp> I mean, both
2020-05-31T01:10:50 < zyp> ULPI transceiver for HS and also hooked to FPGA SERDES for SS
2020-05-31T01:11:16 < zyp> fuckit, 0/1 it is
2020-05-31T01:17:36 < qyx> having a pullup on UART geberates break condition when it is idle, am I right?
2020-05-31T01:17:52 < zyp> no
2020-05-31T01:17:59 < zyp> UART is idle high

2020-05-31T08:21:36 < Cracki> fucking android. system upgrade got stuck somehow because it downloaded the file already but couldn't deal with that, just said insufficient space for download
2020-05-31T08:22:02 < Cracki> poking around in /cache with adb and deleting that thing was required
2020-05-31T08:22:07 < Cracki> how do they make money with that shit
2020-05-31T08:25:39 < Cracki> has anyone here used induction heating (or other method) to get a shrink fit gear off a shaft?

2020-05-31T10:48:31 < Streaker> not trying to defend the Chinese, but if you're making a product and there is an existing one in the market, you try to be pin compatible. that's normal. not a sign of cloning.
2020-05-31T10:48:48 < Streaker> and the specs don't look the same to me. on resistance is different, switching speed is different.
2020-05-31T10:50:22 < turnip420> fair
2020-05-31T10:50:36 < Streaker> a lot of the specs should match actually, since they would be determined by the USB spec
2020-05-31T10:50:43 < turnip420> What's that Chinese stm32 again?
2020-05-31T10:50:59 < turnip420> That's full dye sander mode
2020-05-31T10:51:00 < Streaker> rofl. that's one's an actual clone. I won't defend it.

2020-05-31T10:51:02 < dongs> i wasn't even looking for a USB specific one
2020-05-31T10:51:11 < dongs> but if this one is half price ill take it and retain pin compatibility
2020-05-31T10:51:21 < dongs> but there was a bunch of DPDT china switches too just for generic analog shit
2020-05-31T10:52:06 < turnip420> Yeah cept when the parts stop happening
2020-05-31T10:52:16 < turnip420> Get ready to pay more

2020-05-31T10:52:34 < dongs> then I can jsut go back to fsusb42
2020-05-31T10:52:51 < dongs> or i can dual source depending on whats available at time of assembly
2020-05-31T10:52:59 < dongs> ive been using these in a product that im making 2-3k every month
2020-05-31T10:53:08 < dongs> so if I can cost down and multi-source stuff i'm happier

2020-05-31T11:08:02 < turnip420> 74HC?
2020-05-31T11:08:14 < dongs> HC is not it, thats waht ih ave now
2020-05-31T11:08:25 < turnip420> 3.3 should be active high
2020-05-31T11:08:40 < dongs> Vih at 4.5V is 3.15 max which means 0.7
2020-05-31T11:08:44 < dongs> at 5V it will be 3.5V
2020-05-31T11:09:08 < turnip420> okay
2020-05-31T11:09:52 < dongs> maybe HCT

2020-05-31T11:31:18 < dongs> ds2, would you reuse same 74HCT for multiplying 25mhz clock and switching some LED signals?
2020-05-31T11:31:48 < dongs> i.e. i have a hex buffer that splits 25mhz in 3 clocks and then I put LED driving gpio on remaining 3 
2020-05-31T11:32:03 < dongs> (LEDs are not PWMd, just on/off
2020-05-31T11:34:14 < ds2> at 5V, sure
2020-05-31T11:34:29 < ds2> i think 74HCT can handle 25MHz at 5V
2020-05-31T11:35:01 < ds2> but aren't there better clock focused chips?
2020-05-31T11:35:14 < dongs> 25mhz isnt the problem, i already have it doing that
2020-05-31T11:35:28 < dongs> the reason im even using HCT is because i dont want to pay $5 for a dedicated clock chip
2020-05-31T11:35:32 < dongs> which is literally just some bufers in side
2020-05-31T11:35:48 < dongs> i was just wondering if driving led (at like 20-25mA per pin) would have some negative effect on 25mhz clock
2020-05-31T11:35:55 < dongs> i feel bad wasting half of hex buffer
2020-05-31T11:36:01 < dongs> and I need to drive some leds :p
2020-05-31T11:38:09 < ds2> how many LEDs and how many buffers is free?
2020-05-31T11:38:17 < dongs> 3 leds, e bufferfs is free ;)
2020-05-31T11:38:24 < dongs> *3 buffers
2020-05-31T11:38:25 < ds2> Oh 
2020-05-31T11:38:42 < ds2> are you sinking or sourcing?
2020-05-31T11:38:46 < dongs> sinking
2020-05-31T11:39:11 < ds2> I suspect that should be fine... if you are sourcing, I'd be worried about it lowering theoutput of the other buffers
2020-05-31T11:39:30 < ds2> think plain TTL should be fine
2020-05-31T11:39:32 < dongs> OK
2020-05-31T11:39:38 < ds2> worse case... throw a few transistors
2020-05-31T11:39:47 < dongs> nah trying to cost down. not adding extra shit
2020-05-31T11:39:53 < dongs> 25mhz part alreadty wroks great
2020-05-31T11:40:07 < dongs> ok back to sch then
2020-05-31T11:40:14 < ds2> use a more efficient LED if you are worried
2020-05-31T11:40:21 < ds2> there are stuff that will light up fine at 1mA

2020-05-31T12:44:49 < chipant> May be the dumbest question, but pretty confused regarding enum data types. I see there sizeof operator gives two different value for enum identifier and enum constant belonging to the same enum variable. In my case I see different value in following code : https://pastebin.com/KaSiA19k

2020-05-31T12:52:59 < chipant> PaulFertser, Wondering why not the var1 ?
2020-05-31T12:57:03 < zyp> enums are generally stored in the smallest type they'll fit in
2020-05-31T12:57:03 < PaulFertser> chipant: "It is implementation-defined which type is compatible with any given enumerated type, but whatever it is, it must be capable of representing all enumerator values of that enumeration." https://en.cppreference.com/w/c/language/enum so in your case it's 'char'.
2020-05-31T12:57:48 < zyp> so GEN gets treated as a literal and promoted to int, while the other two are checking the size of the enum type and an instance of that type
2020-05-31T13:10:53 < chipant> So then, as zyp said 'mCG' is an enum type of char a width and 'var1' is instantiated 'mCG' type variable but 'GEN' is a constant does not depend on 'mCG'... I hope I am getting it correctly.

2020-05-31T17:36:05 < PaulFertser> That zipper thing was interesting
2020-05-31T17:38:00 < PaulFertser> What's the deal with that turning off cameras for while they're getting out of the suits. Is there anything "embarrassing" in the procedure?

2020-05-31T17:38:58 < jadew`> I was just wondering if they poop into those suits
2020-05-31T17:39:14 < jadew`> maybe they don't want you to see the full diaper
2020-05-31T17:40:33 < PaulFertser> They're supposed to be on a special diet to be able to easily go without pooping for few days.
2020-05-31T17:42:16 < jadew`> apparently they had a flying poop problem in the early missions
2020-05-31T17:42:59 < jadew`> "Get me a napkin quick," said Apollo 10 commander Tom Stafford with some urgency. "There's a turd floating through the air."

2020-05-31T19:21:33 < jadew`> friendofafriend, move where?
2020-05-31T19:21:54 < friendofafriend> I dunno, where has a nice conversion rate?
2020-05-31T19:22:04 < jadew`> the conversion rate is not the problem
2020-05-31T19:22:11 < friendofafriend> You'll never pay a single GBP again... Oh.
2020-05-31T19:22:23 < jadew`> it's just excessively expensive
2020-05-31T19:22:39 < jadew`> the next and previous size, I can have them 0.5 GBP
2020-05-31T19:22:58 < jadew`> maybe 0.7
2020-05-31T19:23:12 < jadew`> nope, 0.5
2020-05-31T19:23:55 < friendofafriend> I've only just started building up an MPCNC.  It must be nice to have a setup that isn't a steaming pile of PLA and conduit.  ;)
2020-05-31T19:24:31 < jadew`> I was going to buy a CNC, but I decided to build one instead when I have the time
2020-05-31T19:24:43 < jadew`> after watching many videos I realized I can't find the quality I need
2020-05-31T19:24:51 < jadew`> (at a reasonable price)
2020-05-31T19:25:08 < jadew`> so I figured I can just design it and have the parts custom made
2020-05-31T19:25:22 < jadew`> and I can spend the bulk of the difference on a good spindle
2020-05-31T19:25:33 < Steffanx> And spend a shitload of money

2020-05-31T19:30:37 < jadew`> the ones where your phone makes a weird sound and then it starts reading the thing?
2020-05-31T19:30:54 < strata> no. i disable them.
2020-05-31T19:30:56 < jadew`> I was just informed that there's a major fire a couple of km away from me
2020-05-31T19:31:11 < jadew`> strata, lol, why? and can you actually do that?
2020-05-31T19:31:15 < friendofafriend> jadew`: In the US, it's weather, children, nukes.
2020-05-31T19:31:45 < strata> jadew`, i have a KaiOS-based phone and it lets me disable them completely.
2020-05-31T19:32:11 < jadew`> friendofafriend, interesting, in here it was fires, accidental pollution and covid
2020-05-31T19:32:17 < strata> afaik carrier roms of android and obviously iOS make it not possible to disable the alerts
2020-05-31T19:32:32 < jadew`> strata, why do you disable them tho?
2020-05-31T19:32:46 < jadew`> they've never sent useless information
2020-05-31T19:33:02 < friendofafriend> I disable them because if I'm getting a nuke to the teeth, I just want to finish my coffee in peace.
2020-05-31T19:33:09 < jadew`> now I know to keep the windows closed for a day or two
2020-05-31T19:33:10 < Steffanx> i think i can disable it too on my samsung, just disable the channel.
2020-05-31T19:33:41 < strata> jadew`, you keep windows closed for a day or two so the smoke and harmful particles don't come into the house?
2020-05-31T19:34:16 < jadew`> strata, yeah
2020-05-31T19:34:23 < strata> ah. yea good idea.
2020-05-31T19:34:46 < Steffanx> 2 weeks ago i got 4 messages in 15 minutes, a test message the provider sent by accident -_-
2020-05-31T19:34:48 < strata> i wouldn't need a phone to wake me up with an alert about that thuogh. i'd smell smoke close my windows.

2020-05-31T19:54:42 < PaulFertser> Isn't it too unprofessional and clumsy to use an adjustable spanner instead of a properly sized wrench?
2020-05-31T19:54:44 < Cracki> when they pan the waveform, I'd wish for the grid to move with it. those random spinning numbers on the axes are just silly
2020-05-31T19:55:07 < Cracki> one adjustable spanner is less weight than an assortment
2020-05-31T19:55:27 < PaulFertser> Looks like they spent plenty of time for basically shooting a documentary, and just that.
2020-05-31T19:55:34 < Cracki> I guess if they need an actual specific one for lots of uses, they could have that too
