2022-09-07T00:43:01 < octorian> Hmm... Just got an Email about the upcoming ST Developer's Conference next month, and its happening near me. Wonder if I should go. Its free, so I guess nothing to lose but time. 2022-09-07T00:44:46 < octorian> Looking at the schedule, not sure how much of the content will actually be of use to me, but its been so long since I've gone to anything like this it might be worth just going anyways. 2022-09-07T00:51:17 < karlp> given that "safety factors" are _wildly_ application specific, no... 2022-09-07T00:51:27 < karlp> and "0805" is kinda vague, 2022-09-07T00:51:44 < karlp> read the part specs in question, don't assume all parts are identical if these things matter. 2022-09-07T00:52:08 < karlp> in resistors for instance, you can get substantially higher rated parts from various vendors, but you'll pay for it. 2022-09-07T00:56:52 < machinehum> Yeah makes sense 2022-09-07T00:57:12 < machinehum> It seems like most people also stack resistors 2022-09-07T01:04:35 < qyx> yes nearly all AC/DC PSU designs have a few 1206 or so in series for voltage sensing 2022-09-07T01:05:24 < qyx> I am generally good with two 1206 in series for 230 V AC and yolo, but you should check 2022-09-07T01:06:21 < qyx> but I have seen up to 4 2022-09-07T01:09:45 < karlp> our current gen has 2 bourns HV 1206 resistors, 3 HV 0805s are cheaper but physically larger. 2022-09-07T01:10:04 < karlp> I've seen atmel reference designs that use _7_ 0603 standard resistors... 2022-09-07T01:11:45 < karlp> sorry, we used 2x 2010 sized, 2022-09-07T01:11:54 < karlp> (to get 4kV) 2022-09-07T01:14:03 < karlp> https://imgur.com/a/A0ACWL3 for inspiration... 2022-09-07T01:14:14 < qyx> huh 2022-09-07T01:14:23 < qyx> "standard" 0603 is 50 V, isn't it? 2022-09-07T01:14:39 < karlp> well, I dunno what "standard" really means. 2022-09-07T01:14:42 < qyx> so they are heading for exactly 315 Vpk? 2022-09-07T01:15:11 < karlp> but the atmel atm90e3x references have 7 0603 parts, most of the AD metering parts use 4? 2022-09-07T01:15:13 * karlp shrugs. 2022-09-07T01:15:30 -!- hackkitten [~hackkitte@2a00:6020:5090:5700:5974:c4eb:c9c6:4849] has quit [Ping timeout: 248 seconds] 2022-09-07T01:27:41 -!- boB_K7IQ [~boB_K7IQ@152.44.147.180] has quit [Ping timeout: 252 seconds] 2022-09-07T01:58:16 < machinehum> My mind goes to the breakdown from air across the pads... but obviously breakdown though the part is might lower 2022-09-07T01:58:24 < machinehum> much* 2022-09-07T02:03:44 < machinehum> I'm designing a mains device that's driving a load, it uses a PMIC that drives FETs and has a overcurrent protection. It monitors current and shuts off the fets is there is an overcurrent event 16 times in a row (latches them off). Is that reasonable as a primary protection 2022-09-07T02:04:08 < machinehum> I guess it would also make sense to add a fuse at a higher current rating on the output if that fails 2022-09-07T02:07:11 < machinehum> It's kinda interesting because it's a light dimmer rated to 150W, but if someone wires in something higher than 150W the device will trip the overload and won't reset until a power cycle... which is removing the dimmer and rewiring it in it's junction box 2022-09-07T02:08:32 < machinehum> I was going to use a PTC but they're huge for that wattage 2022-09-07T02:11:18 < specing> dimmer? Who still uses those? 2022-09-07T02:12:04 < machinehum> It's a smart dimmer, wifi connected 2022-09-07T02:12:12 < machinehum> Uses a fancy trackpad 2022-09-07T02:12:13 < specing> machinehum: what if someone uses it to dimm a cluster of incandescents? 2022-09-07T02:12:25 < machinehum> specing: This is the issue, yes 2022-09-07T02:13:01 < machinehum> Write 150W on the box and it's their problem I guess 2022-09-07T02:13:04 < qyx> why is it only 150 W rated? 2022-09-07T02:13:43 < machinehum> Because that's what the client wanted 2022-09-07T02:13:49 < specing> aha 2022-09-07T02:14:12 < qyx> I would not fuse such thing with a 10 A breaker 2022-09-07T02:14:56 < machinehum> So just rely on the overcurrent, something happens... 10A goes? 2022-09-07T02:14:58 < machinehum> Makes sense 2022-09-07T02:14:59 < qyx> idk if the code even allows that 2022-09-07T02:15:27 < machinehum> Fusing the output of a mains device? 2022-09-07T02:16:14 < qyx> no, use a device not rated for at least 10 A for a lighting circuit 2022-09-07T02:16:36 < qyx> like you are not allowed to use wires smaller than 1.5 mm2 2022-09-07T02:16:41 < qyx> or switches, etx 2022-09-07T02:16:45 < qyx> *etc. 2022-09-07T02:17:59 < machinehum> https://imgur.com/a/IBJLAK8 2022-09-07T02:18:04 < qyx> I would rate the thing at least for the current which safely trips the overcurrent device without catching fire 2022-09-07T02:19:09 < machinehum> That dimmer on the left is just 150W 2022-09-07T02:19:22 < machinehum> What happens when you exceed 150W: unclear 2022-09-07T02:20:33 < karlp> that you think it's "interesting" that an easily envisaged use case requires an end user to "rewire the device" rather than "fundamental design flaw" says a lot to me :) 2022-09-07T02:21:13 < machinehum> Dude it's just what the IC does 2022-09-07T02:21:23 < machinehum> It's a part for a smart dimmer 2022-09-07T02:21:46 < bitmask> ugh 2022-09-07T02:21:50 < bitmask> what a waste of a day 2022-09-07T02:22:04 < bitmask> took like 6 hours to figure out these stupid template classes 2022-09-07T02:22:21 < qyx> karlp is right in that regard 2022-09-07T02:23:34 < machinehum> Polyfuse it is then 2022-09-07T02:23:51 < qyx> it is one thing if the pmic latches off to save itself 2022-09-07T02:24:12 < qyx> the whole device lathing off is a totally different thing 2022-09-07T02:25:28 < machinehum> No... the PMIC switches into a mode that disables it's fets 2022-09-07T02:26:02 < qyx> what happens if a bulb is shorted? 2022-09-07T02:27:10 < qyx> is your device able to handle Ipk? 2022-09-07T02:28:38 < machinehum> 60hz would start it's rise, exceed Imax, PMIC would shutoff the FETs. This happens 16 more times and doesn't turn on the FETs again 2022-09-07T02:29:19 < machinehum> However... there isn't a reset pin on the PMIC anywhere, so a power cycle is required it seems 2022-09-07T02:29:49 < machinehum> I am quite curious what would happen to the 150W dimmer I listed earlier 2022-09-07T02:29:57 < machinehum> Ipk?

you have driver.dll. you rename driver.dll to driver_old.dll and you create a driver.dll which loads driver_old.dll and exports same interface 2022-09-23T15:40:26 < benishor> and simply delegates the calls to the loaded dll 2022-09-23T15:40:37 < benishor> this allows you to control 2022-09-23T15:40:46 < benishor> what happens before the call and after the call 2022-09-23T15:40:53 < jpa-> and then the dll you delegate the calls to *still* creates its worker thread that *still* just runs the code in the original dll, and nothing changes 2022-09-23T15:41:30 < benishor> something changes; you get to catch the uncaught exception 2022-09-23T15:44:04 < jpa-> it's not like the dll does CreateThread(GetProcAddress(....)), it creates the thread to run the function that is directly linked in the same

2022-09-23T23:29:25 < Laurence_b> only very small, as there is a laminated back iron ring between the magnets and wheel 2022-09-23T23:30:12 < Laurence_b> turns out to be stable the harmonic canceller needs to work on pairs : n+1, -n+1 2022-09-23T23:30:24 < Laurence_b> so 6th harmonic is +7,-5 2022-09-23T23:31:08 < Laurence_b> so each harmonic canceller is park -> PI loop -> inverse Park 2022-09-23T23:31:57 < Laurence_b> in a pair, with angle*(n+1) for one and angle*(-n+1) for the other 2022-09-23T23:32:40 < Laurence_b> TMS320 has very fast hardware CORDIC, so I'm not sure why its taxing the cpu so much 2022-09-23T23:33:53 < catphish> Laurence_b: how powerful is this invertamajig?
