00:35:15 <Kuschelpony> quick question: do you know any halfway common regulator similar to the LM317 with lower internal reference (probably not existing as its the silicon bandgap voltage) or a kind of power J-Fet with an sharp threshold voltage less than 1V or so?
00:36:42 <Kuschelpony> im looking to implement a mix of precise voltage regulation (done by an TLV431) and some current limit without too much drop, like the Ube of the L200 did
00:40:14 <rust_collector> I have not heard of a lower voltage reference common-ish regulator. no. I do not really know anything about jfets. sorry.
00:41:22 <rust_collector> hmm, when you get going, would you mind showing me a bit?
00:43:38 <Kuschelpony> im sorry i cant translate?
00:45:50 <rust_collector> can I look at your device, when you start making it?
00:46:02 <Kuschelpony> ooh, no problem!
00:46:36 <rust_collector> I have a thing for power supplies, but I don't really know anything, lol
00:46:40 <Kuschelpony> its just a very simple circuit that i want to set up for an galvanic cell
00:46:50 <Kuschelpony> well lets chat for more months :)
00:47:29 <Kuschelpony> i think i can describe it in some words: think about the common current regulator with the LM317 and one resistor in the output
00:47:30 <Ampera> https://cdn.discordapp.com/attachments/449968711789445127/803254174321737728/20210125_082459.jpg
00:47:32 <Ampera> biltong in progress
00:47:50 <rust_collector> yep, I will probably not go anywhere, lol. now If I could just get fired from my job, I would have time to mess with things
00:48:10 <Kuschelpony> that has an voltage loss of 1.25 ref voltage plus the dropout voltage of something 2 to 3V
00:48:26 <rust_collector> yes
00:48:37 <Kuschelpony> now there is a clever circuit that attaches an TLV431 for voltage regulation to the lower pin of the LM317
00:49:11 <Kuschelpony> that could regulate up from something 2.2V where the TLV has its internal dropout of about 1V plus the ref of the LM317
00:49:31 <Kuschelpony> im looking to build the same with lower dropout
00:50:03 <Kuschelpony> that i could regulate from less than 2v upo and keep current limiting, and ideally all sourced from a single 5V supply
00:50:19 <Kuschelpony> the lkatter rules out the LM723
00:51:18 <Kuschelpony> something like https://2.bp.blogspot.com/-i4F1bpvSAC8/Xf56F2TIyjI/AAAAAAAAOlI/XX_cjXR6IxAoEoNt7YaDqMlRyJhuikQ7QCLcBGAsYHQ/s840/li-ion_charger_lm317_schematic.png minus the fan and all primary
00:57:53 <rust_collector> hmm, that is interesting.
00:58:01 <rust_collector> 5v is not much
00:59:54 <Kuschelpony> i know, but easily available supplies of 5V 2A and also i dont want to waste too much with heath from a higher starting voltage
01:00:02 <Kuschelpony> or....
01:00:38 <Kuschelpony> there is a kind of convenient switching regulator with externally selectable current limit that works smooth down to zero volt
01:03:43 <rust_collector> now. I am not really following what you want to do. a galvanic cell is pretty much a battery, isn't it? Why do you want a power supply for that?
01:05:32 <Kuschelpony> i meant the kind of galvanic cell to do electrolysis and galvanoplating
01:05:39 <rust_collector> ah, ok
01:06:25 <Kuschelpony> and for that i need an coars switchable current limit plus an somewhere precise voltage limit when i want that A happens but just below the voltage where B would happen as well
01:06:48 <Kuschelpony> for example to remove all tin from copper but not also oxidise the copper
01:07:00 <Kuschelpony> or make H2 + O2 gas mix
01:07:13 <Kuschelpony> i meant to also NOT make the gas mix
01:07:44 <rust_collector> I do remember filling grandpas shed with all kinds of gasses, lol
01:08:10 <rust_collector> interesting project
01:10:12 <K> ass gas.
01:10:22 <K> i apologize.
01:10:24 <rust_collector> that too
01:10:41 <Kuschelpony> hihi
01:11:19 <rust_collector> and the jfet was for current regulation?
01:11:27 <Kuschelpony> i do see very few uses for a mix of CH4 and CO2 with humanly detectable amounts of H2S
01:11:40 <Kuschelpony> the JFET operates in some way like a very imprecise LM317
01:12:14 <rust_collector> ok
01:12:35 <Kuschelpony> i do see very few uses for a mix of CH4 and CO2 with humanly detectable amounts of H2S, except in situatiuons where you would enjoy a bit more of social distancing to some people in shops
01:12:55 <Kuschelpony> when you feel them bumping in your backpoack
01:14:28 <rust_collector> I guess scientists can figure out something to use it for, but that reason is good enough for me
01:18:28 <rust_collector> hmm, it is getting colder here. it is a good time to stay in front of the confuser
01:20:26 <K> didya get any slow recently, rusty?
01:20:29 <rust_collector> Ampera, that looks pretty chunky for being jerky-like? But I bet it will be great
01:20:34 <K> we are promissed 30cm this evening/night
01:20:40 <rust_collector> I am always slow.
01:20:55 <K> ah.
01:21:15 <rust_collector> Meh, we had a bit on friday and saturday, but not much. I guess we got around 4" or so
01:23:47 <Kuschelpony> im off until later evening
01:23:54 <rust_collector> have fun

01:30:34 <rust_collector> that one exists
01:30:54 <Ampera> that's not much soup
01:31:06 <rust_collector> nope, it was all that was left
01:31:17 <Ampera> what about what was right
01:31:29 <rust_collector> the fork
01:31:40 <Ampera> eat the fork then
01:32:00 <rust_collector> no, I don't have any tooth
01:33:19 <Ampera> did you eat them?
01:33:22 <rust_collector> so, this was veg soup from yesterday. and there was just enough to cook a block of noodle
01:33:24 <rust_collector> yes
01:34:55 <rust_collector> I should make more soup
01:35:24 <rust_collector> it tends to be more like an emergency meal now.

02:27:35 <K> aaarhh, the fucking pickle just fell out of my sammich, rolled along my hand and fell into tea
02:27:59 <K> treason
02:29:17 <rust_collector> hah!
02:29:31 <rust_collector> that is what you get for drinking tea
02:32:04 <K> :|
02:33:53 <steve30> One of the problems with parametric searching. Is the item I want a 'plug' or a 'jack'
02:36:09 <rust_collector> well, that depends on what you are looking for?
02:36:10 Join: Kuschelpony ([email protected]) to #EEVblog
02:39:13 <rust_collector> in my opinion (tm) a jack is a hole, probably in a panel, but maybe on a cable, the plug is the part that you plug into a jack?
02:39:58 <steve30> https://cpc.farnell.com/w/c/cable-leads-connectors/connectors/audio-video-connectors/jack-connectors?no-of-contacts=3contacts&gender=jack%7Cplug&range=inc-in-stock&sort=P_PRICE
02:40:19 <steve30> Some are categorised as Jacks, some as Plugs. And in the description is says 'jack plugs'.
02:41:16 <rust_collector> well, I would think a jack plug is a plug. but yes, it probably depends on who added them to the list
02:41:46 <steve30> I don't really care what they are /actually/ called. It just makes parametric searching hard.
02:43:00 <rust_collector> well, at least on the first page of that, jacks are what a plug goes into?
02:43:28 <rust_collector> except the one on the bottom, which is a jack pug
02:45:21 <rust_collector> which imo should have 4 legs
02:57:16 <Ampera> if a jack is a hole, what is a jill?
02:57:52 <rust_collector> sounds like a skin problem
02:58:17 <rust_collector> i have a jill on my nose.... yes, that is probably it
03:00:58 * Ampera removes rust_collector's skin so he won't have any skin problems anymore

03:06:39 <rust_collector> the budget way to lower your car
03:20:47 <rust_collector> heh, now it is getting almost winter like outside. 15 degrees. it was 20 something a bit ago
03:22:41 <Ampera> it's 25 out right now
03:22:43 <Ampera> it was 10 earlier
03:23:03 <Ampera> I think wind chill was something like -9
03:23:25 <rust_collector> hehe, ok
03:23:36 <Ampera> this all in Fahrenheit
03:23:40 <rust_collector> yes
03:25:09 <rust_collector> I still think it is a bit strange to hear americans talking about temps. because I think you are the only ones who talk about wind chill, and such. or effective degrees.
03:25:47 <K> yr.no has "feels like" column
03:25:53 <K> is quite accurate
03:27:26 <rust_collector> yes
03:28:25 <rust_collector> but I never hear people mention that. it is often more like "it is -20, abut it feels cold"
03:40:36 <coppice> the value of using wind chill in weather broadcasts depends on lot on how windy the place it
03:42:01 <rust_collector> well, the value of it... you still have to go outside and do what you have to
03:42:17 <Ampera> then why have temperature at all
03:42:20 <Ampera> or weather forecasts
03:42:26 <Ampera> just fucking deal with it who fuckin cares
03:42:28 <rust_collector> I don't know?
03:42:42 <Ampera> you don't know?
03:43:18 <rust_collector> not for little things like this. but if I was on a small fishing boat in the midle of the sea, sure
03:47:57 <rust_collector> I guess people like to talk about it. but I do not see all that much use for it, for most people. They can tell me if there is something special they expect to happen, but if it is 10 or 15 degrees is not really that important, I guess
03:48:32 <rust_collector> but, have fun, I am going to work

05:14:51 <Nothing\> ahoy ahoy
05:15:10 <Nothing\> man, the coils in this new piece of crap ecig i bought are terrible
05:15:19 <Nothing\> i'm changing them almost every week or two
05:15:27 <Nothing\> the ones in my last ecig would last nearly a month each
05:16:07 <Nothing\> this latest one seemed to have a loose connection or something cuz it'd make this quiet buzzing sound, almost like a set of hair clippers
05:16:16 <Nothing\> so they must be using PWM
05:16:32 <Nothing\> hell, i should hook the contacts up to my scope and see what's coming out of it
05:17:19 <hsn> Morning T3sl4
05:17:32 <hsn> EEVBlog time in T3sl4
05:17:42 <Nothing\> question though: if i accidentally hooked the ground lead of my scope up to a point that's common with the probe, but not common to mains, would that cause damage
05:17:47 <Nothing\> like something battery powered
05:17:52 <hsn> 12:17 ?
05:17:56 <Nothing\> i know it'd cause damage if it was referenced to mains
05:18:00 <T3sl4> Kuschelpony: yeah, they make them pretty high, IGBTs too, though good luck finding them, pretty sure they're all restricted/special order something or other?
05:18:17 <Nothing\> hey T3sl4 how ya doing buddy?
05:18:22 * Nothing\ hugs T3sl4
05:18:23 <T3sl4> hey Nothing\
05:18:27 <Nothing\> and you too hsn
05:18:34 <Nothing\> how are you, man?
05:18:40 <hsn> Nothing\: not common with mains but with scope earth lead?
05:18:53 <hsn> Im good and u?
05:19:05 <Nothing\> i'm doing alright. hangin in there. you know?
05:19:09 <T3sl4> nothing should be common to mains, thats why we isolate it?
05:19:29 <hsn> T3sl4: except before isolation
05:19:38 <hsn> :P
05:19:45 <Nothing\> but yeah, ie if you had a circuit running on batteries and connected the scope probe and the ground lead of the probe to a point with the same voltage
05:19:59 <Nothing\> or alternately, a higher voltage than the probe
05:20:32 <T3sl4> a higher voltage what? it's battery isolated, and there are no absolute voltages
05:20:33 <Nothing\> T3sl4, i meant referenced to mains ground, i think
05:20:43 <Nothing\> whatever the hell dave was on about in that video about not blowing up your scope
05:21:17 <Nothing\> cuz the ground lead is connected directly to your mains ground, so if you connect it to something live that's reference to mains ground you'd blow up your scope
05:22:41 <Nothing\> i don't do anything with anything connected to mains anyways so i don't have to worry about that
05:22:54 <Nothing\> 9v battery holders ftw
05:23:05 <T3sl4> well yeah, don't go probing a mains referenced circuit with a ground referenced scope
05:24:01 <Nothing\> those bunny ear clips are all well and good, but they're not meant to be reattached to batteries as often as is needed for making electronics, so the solder joint holding the wire to the connector would inevitably break
05:25:51 <Nothing\> lol oh yeah, so i cracked open a 5055 high voltage BJT the other day
05:25:56 <Nothing\> this is what i found inside
05:25:58 <Nothing\> https://ibb.co/VYs93QW
05:26:50 <Nothing\> 3055
05:26:52 <Nothing\> not 5055
05:28:08 <Nothing\> where the real ones don't have any epoxy at all, and have a much larger die
05:28:44 <Nothing\> got this out of one of those elenco assorted transistor kits i bought on amazon when i first got started. So it seems the skimp on their parts.
05:29:09 <Nothing\> or don't know how to spot fakes, but it's not that hard once you know what to look for.
05:29:37 <T3sl4> looks about right
05:35:57 * hsn probes T3sl4's leads while he stands on copper earthed plate
05:36:32 <T3sl4> owo
05:38:36 <hsn> T3sl4 what if a battery powered product has metal chassis and charging port ..
05:39:29 <hsn> Then the pcb isolated part has gnd which is connected to chassis ?
05:40:29 <T3sl4> maybe
05:40:31 <hsn> Or that would be connected through a high Kv cap like 100pF ?
05:41:36 <hsn> Ok so if its connected to chassis .. then these voltages cant be probed .. and u ve to ve isolation transformer either on the scope or the product?
05:44:55 <K> T3sl4, i've found a grave error on this page - https://www.seventransistorlabs.com/Calc/XMEGABaud.html
05:45:20 <T3sl4> how acute of you
05:45:33 <K> it is not "Half Clock", but "Double Clock"
05:47:09 <T3sl4> half period? shrug
05:47:14 <Kuschelpony> just to say: there are very close to zero reasons to put your scope on an isolation transformer, but one good reason - your life - to never do it
05:48:30 <T3sl4> K: corrected, thanks :)
05:49:12 <hsn> Now that u correct it .. T3sl4
05:49:17 <hsn> Im confused
05:49:18 <hsn> Lol
05:50:48 <hsn> Guys.. i love my wife
05:51:17 <hsn> Sorry the kid (wife) was holding the phone...
05:51:48 <T3sl4> kid wives are illegal most places
05:51:55 <T3sl4> but i suppose they do things differently over there
05:53:51 <hsn> Nah
05:54:01 <hsn> My wife is old kid
05:55:37 <Nothing\> there we are
05:55:42 <Nothing\> i just removed the epoxy
05:55:54 <Nothing\> apparently isopropanol works really well for removing white epoxy
05:56:23 <Nothing\> lol and the damn bond wires were just held in place by the epoxy
05:56:49 <Nothing\> the first bit i got, I sorta peel a layer of epoxy off, and the bond wires just came with it
05:57:04 <Nothing\> or one of them did, the other came off after i peeled off a deeper layer
05:57:33 <Nothing\> coulda been i just broke the ultrasonic weld, but i wasn't pulling very hard
05:57:35 <T3sl4> hate to break it to ya, but that wasn't epoxy
05:57:42 <Nothing\> lol probably not
05:58:09 <Nothing\> T3sl4, https://www.youtube.com/watch?v=d_5eo1AWOAo&ab_channel=karllark
05:58:21 <Nothing\> just pretend he's talking about the epoxy
05:59:29 <hsn> Hot glue gun is cool to hold wires
05:59:44 <hsn> And to get peeled of as well
05:59:48 <T3sl4> it does kinda look like monkey cum
06:00:19 <Nothing\> lol T3sl4 how would you know what monkey cum looks like? you have a bad experience at the zoo as a kid, too?
06:00:23 <hsn> Im no expert in monkeys' cum so no comment from my side
06:00:42 <Nothing\> hsn, oh absolutely, to hold wires in place to stop em "flappin' in the breeze" as dave says
06:00:52 <hsn> :p Nothing\ same comment different approach
06:00:54 <Nothing\> but not as a replacement for an ultrasonic weld an an IC
06:00:56 <T3sl4> well you see, there's something you didn't know about your mother
06:01:09 <Nothing\> T3sl4, she's made of monkey cum?
06:01:21 <T3sl4> yes
06:01:25 <T3sl4> it's a hell of a drug
06:01:29 <Nothing\> lol
06:01:42 <Nothing\> i decided to dl that movie cuz i realized i never did watch it
06:01:48 <Nothing\> despite intending to for the last 25 years
06:01:55 <Nothing\> and loving kids in the hall
06:02:06 <Nothing\> imo it's the best original canadian show we've ever made
06:02:12 <Nothing\> even better than trailer park boys
06:02:13 <K> monkey com movie? what?
06:02:41 <Nothing\> yeah, kids in the hall: brain candy
06:02:52 <Nothing\> i tihnk it's about this wonder drug antidepressant or something
06:03:39 <Nothing\> but i've always loved kids in the hall. And not just because I have fond memories of watching them when I came home for lunch from school and had US satellite, so I got comedy central
06:03:42 <hsn> im confused .. when this https://images.app.goo.gl/ZofcdygFaXwwJeh77 vs when this https://images.app.goo.gl/2Jzobsztpf4wgSup6
06:03:49 <Nothing\> cuz it used to run on comedy central on syndication
06:04:17 <Nothing\> the only one that really went on past that show i think was scott thompson
06:06:32 <Nothing\> hsn: lol i clicked a thing about various grounding terms on there that wound up being an advert. I'm immediately accosted by a computerized MS SAM type voice telling me how I can free up computer memory with their software.
06:06:59 <Nothing\> part of me knew it was an ad but i figured at least it'd take me to something relevant
06:07:47 <hsn> Nothing\: i just shared it from google images never opened one
06:07:49 <Nothing\> EWWW and I just did that on microsoft edge with no add-ons
06:07:53 <Nothing\> i feel so dirty now
06:08:01 <hsn> Hwo ever have fun reading this https://www.eevblog.com/forum/beginners/signal-ground-vs-chassis-ground-should-they-be-coupled/
06:08:11 <Nothing\> right on, thanks
06:08:53 <Nothing\> i have a fairly good understanding, but not a solid one. So it would be helpful to go through something like that
06:12:08 <Nothing\> ever since i went on clonazepam i've pretty much given up trying to learn anything new since it affects my memory so bad, i forget what i'm talking about in mid-coversation. Nevermind being able to retain any complex information.

06:24:04 <Ampera> I haven't run for a few days, but I'm fucking broken like shit
06:24:15 <hsn> 42, Ampera!
06:24:24 <Ampera> what's unanswered, hsn, did you ping me?
06:24:36 <hsn> EEVBlog: 42, hsn!
06:24:40 <hsn> Why
06:24:42 <hsn> What
06:24:45 <hsn> And when
06:24:52 <Ampera> 30F out
06:24:59 <Ampera> wind seems calm though
06:25:20 <Ampera> it used to be my lungs that were fucked when running, now it's my legs
06:25:21 <hsn> Im calm.. until ur bot started throwing numbers on me
06:25:26 <Ampera> I just have no stamina
06:25:47 <Ampera> yeah it does that, hsn
06:25:50 <hsn> Reminds me of me
06:26:21 <hsn> I can run for 10 meters
06:26:22 <Ampera> oh come on, hsn, it's not /that/ annoying
06:26:57 <hsn> Ampera: understand my speciality
06:27:21 <hsn> Im bot studier and discovery guy
06:27:39 <hsn> And its a mystery to me
06:27:54 <Ampera> you've discovered everything it can do already
06:28:01 <hsn> read half of it and get desprate then leave it unanswered in mind
06:28:14 <hsn> I didnt discover when to trigger the 42
06:28:27 <hsn> Gaycount++
06:28:46 <Ampera> It's purely random when you happen to say certain words
06:28:47 <hsn> And that thing is either broken or
06:29:07 <hsn> Random distribution
06:29:18 <Nothing\> Ampera, running is a very high impact thing for your legs. I've had chronic knee problems since I was a kid and 2 weeks of daily jogging had me in agony
06:29:19 <hsn> Or normal distribution
06:29:33 <Nothing\> the doctor suggested swimming or cycling as lower impact alternatives
06:29:57 <Nothing\> swimming is actually a great exercise, but obviously you need to have an indoor public pool to do it in
06:30:14 <hsn> I like the beach swimming
06:30:16 <Nothing\> and i absolutely can't swim because my body freaks out about sudden temperature changes
06:30:28 <hsn> Except the gloves animal
06:30:31 <hsn> It burns
06:30:46 <Nothing\> last time i tried swimming, i literally felt like i was dying when, after an hour of fiddling about, I finally just decided to dunk myself under
06:31:04 <hsn> Gloves sea animal
06:31:21 <Nothing\> felt like i was freezing to death, even had that feeling of it sucking the breath out of me. If you've ever dove into cold water
06:31:50 <Nothing\> alright i've got an hour before my head shrink appointment so i think i'll play some gta and maybe go to the bathroom
06:31:55 <Nothing\> have a good one, guys
06:32:09 <hsn> Enjoys man
06:32:19 <Nothing\> will do!

07:35:27 <Ampera> awpeui
07:35:28 <Ampera> and awoifh
07:36:52 <hsn> Ysjoelfir: idk the guy called for meeting and starting adding requirements that i dont like so i told him yeah sure sure then i left and never touch it .. so if he wants to order what was designed i ll .. other wise im not gonna redesign
07:37:39 <Ysjoelfir> lol. sounds like my customer with his ever changing ideas
07:38:13 <hsn> Ofc at beginning i tried to tell him no u cant change and have pcb that have wings and fly .. but since he didnt get it
07:38:29 <hsn> I just did the "sure sure" topology
07:38:40 Join: Guest|90682 (Guest90682`[email protected]) to #EEVblog
07:38:43 <Ysjoelfir> hehe^^
07:38:50 <Ysjoelfir> well, sometimes that is neccessary
07:39:22 <hsn> Indeed .. he wanted as ring at begining
07:39:52 <hsn> Now he wants it "general purpose dev board that fits for bluetooth mesh networking"
07:40:52 <Ysjoelfir> eh? wth?
07:40:59 <Ysjoelfir> thats like... a complete different thing
07:41:01 <hsn> And i was like .. dude .. this design is my first rf design and this antenna and board size is challenging to me .. and it just wong give u distancw
07:41:14 <hsn> Distance
07:42:01 <hsn> He just want to pay for this board and use for few different streams
07:42:27 <hsn> Like .. one for ring .. another for some other wearable .. etc etc
07:43:04 <hsn> And have the connector to be modular with like .. SPI, i2c .. etc ..
07:43:07 <Ysjoelfir> pfff.... well.... no.
07:43:31 <hsn> No Ysjoelfir
07:43:41 <hsn> It's not "no"
07:43:48 <hsn> Its "sure sure"
07:43:59 <hsn> We can do that .. see u later sir
07:44:23 <Ysjoelfir> but my customer is also very great atm.... he doesn't want to pay for assembly by a company, so he wants me to assemble it. great, I love assembling stuff with hot air
07:44:23 <hsn> :p
07:44:37 <hsn> Huh
07:44:44 <hsn> 0204?
07:44:59 <hsn> After he forced for small right?
07:45:15 <T3sl4> Ysjoelfir: put on some heavy metal and keep the hourly charge going. what's the problem? :)
07:45:41 <Ysjoelfir> nah, its fine, but assembling 4XSON is a pretty big PITA^^
07:45:48 <hsn> T3sl4: i think the problem in the tweezers :)
07:46:27 <hsn> 4xson?
07:46:36 <T3sl4> "problem exists between user and tweezers"
07:47:57 <Ysjoelfir> take a look at the drawing of that package ^^ https://www.ti.com/lit/ds/symlink/tlv713p.pdf?HQS=dis-dk-null-digikeymode-dsf-pf-null-wwe&ts=1611579399583
07:50:10 <T3sl4> it's just a grain of sand, what's the big deal?
07:50:40 <Ysjoelfir> pretty much^^ its roughly as big as two lines of my fingerprint.
07:51:04 <hsn> Eevblog convert sand to T3sl4 time measurement unit
07:51:05 <EEVBlog> I wasn't able to parse that correctly, please see EEVBlog Help for more details
07:51:21 <hsn> ⌛
07:52:08 <hsn> Speaking of the regulator
07:53:01 <hsn> I used lm8177 in bowl ctrl whatever and now i dont like its v drop of 1.2v
07:53:24 <hsn> Its doing 5v to 3v3 ..
07:53:50 <Ysjoelfir> sounds fine to me?
07:54:09 <hsn> But i dont like it because now im goijg to have 1mF cap in 5v rail to ve 20ms to save error log
07:54:14 <hsn> At power loss
07:55:13 <hsn> For that i wanted the regulator to have as low as possible
07:55:58 <hsn> Also that 1mF is alot .. how much time should i ve for power loss event saving
07:56:31 <hsn> The 5v uses 180ma or somthing ..
07:56:53 <T3sl4> use a sepic
07:57:19 <Ysjoelfir> but don't mistake it for a septic
07:59:04 <hsn> Makes sense ..
08:01:22 <hsn> So 5v rail -> sepic 3v3 -> mcu and adc circuit
08:01:23 <hsn> Or
08:01:23 <hsn> 5v0 rail -> sepic 4.5v -> regulator 3v3 -> mcu and adc
08:01:48 <Ysjoelfir> what advantage would the second version have?
08:01:57 <hsn> Lower noise
08:02:02 <hsn> I guess
08:02:20 <Ysjoelfir> is that beneficial for that application? also, you can always filter your VCC
08:04:58 <hsn> Its probably not .. just me noob cant specify the stuff regulators provide "noise rejection ratio" / the load regulation / ripple/ accuracy .. etc
08:06:26 <hsn> I can only see some online 1st order .. 1/sqrt(2piLC ) equation or somthing but jm not sure it will work properly
08:07:05 <T3sl4> just filter the damn thing
08:07:28 <T3sl4> ppl try to filter with LDOs, without checking if it's even necessary, besides they're terrible at it
08:08:25 <hsn> Today i was scoping the vin 24v even though it has LC filter .. i didnt like that 200mV noise ..
08:08:46 <hsn> On both input and output
08:09:45 <hsn> Although im not sure if the 200mV is gonna radiate or is it acceptable or not EMC wise
08:10:40 <T3sl4> dont forget to probe ground
08:13:05 <hsn> Huh
08:13:48 <hsn> Probe lead was taken off and had the short version ..
08:13:50 <hsn> XD

08:51:07 <TheDude> hi
08:52:21 * T3sl4 hugs TheDude
08:52:47 <TheDude> so
08:53:00 <TheDude> I've read up on the booting process of linux
08:53:23 <TheDude> how the whole bios to fsbl, to ssbl, to loading the kernel, doing the init works
08:53:44 <TheDude> and how that translates to the thing I'm trying to work with, which is the Zynq
08:54:13 <TheDude> now there's just the teeny tiny task of actually getting something to bloody work on that board :D
08:57:19 <TheDude> also how things work in terms of kernel space, user space, system calls
08:57:22 <TheDude> where the drivers reside
08:57:38 <TheDude> there the GNOO libraries are :D
08:57:52 <TheDude> all of that good stuff

10:21:09 <EEVBlog> New EEVBlog Tweet: What happens when you accidentally type "eevblog blow up" into ebay instead of Youtube. #NSFW https://t.co/a1XhSrs2aM
10:34:29 <T3sl4> Ysjoelfir: you know the slug ship event that says they're going to burn you out? i just got one with only beams. they can't pierce even 1 shield
10:36:10 <Ysjoelfir> jep, I know that one. can be.... not nice at all^^
10:40:05 <T3sl4> always buy upgraded oxygen before entering nebulas :>
10:48:18 <Ysjoelfir> Interestingly I think I never (or at least not more often than probably once?) died from suffocation
10:52:45 <Halcyon> https://thewoksoflife.com/dan-dan-noodles/
10:52:50 <Halcyon> Holy crap they look good
10:53:19 <T3sl4> forget if i've lost a run to it, but flagship hacking your level 1 oxygen is pretty bad
10:54:00 <Ysjoelfir> thats true
10:54:39 <Ysjoelfir> I seem to be lagging somehow oO your comments basically popped up a few seconds before I typed mine, but the timestamps say it has been 3 minutes
10:54:41 <Ysjoelfir> strange
10:54:42 <T3sl4> neat thing about ion builds, you can get crew kills that way.... if you have the patience of a diabolical saint
10:54:54 <T3sl4> check your clock sync? :P
10:55:10 <Ysjoelfir> hah, and that one is from 0:52, while it is already 0:55
10:55:44 Join: arch ([email protected]) to #EEVblog
10:55:45 <Ysjoelfir> oh, maybe the clock on my NAS (which runs this bouncer) is out of sync. hm.
10:55:53 <Ysjoelfir> also Halcyon, that looks... not bad at all
10:56:10 <Ysjoelfir> you should try chapaghetti though
10:56:23 <Halcyon> What's that?
10:56:44 <Ysjoelfir> ramen, but not cooked as a soup but more like stir fried, with a black bean paste sauce thing
10:56:59 <Halcyon> Ooooh
10:57:14 <Ysjoelfir> T3sl4, regarding to the ions: I am always a diabolic vilain :D
10:57:44 <T3sl4> you should play fire beam builds more often
10:57:50 <Ysjoelfir> Halcyon, I might make myself a bowl of those soon. I am craving something very savory.
10:57:55 <T3sl4> there's a blue option event that's particularly diabolic
10:58:01 <Ysjoelfir> T3sl4, I thought about doing that some times^^
10:58:21 * arch splashes hotsauce on T3sl4's crotch
10:58:43 * T3sl4 makes arch lick off his cock sauce
10:58:50 <arch> touche
10:59:04 * Ysjoelfir feels the urge to wash his eyes with acid now
10:59:22 <T3sl4> Ysjoelfir, sriracha
10:59:29 <Ysjoelfir> close enough
10:59:35 <T3sl4> :DD
11:04:41 <Ysjoelfir> erm.. https://www.ebay.de/itm/Logitech-g-510-sehrguter-Zustand/114645929958
11:05:10 <Ysjoelfir> translation: "Logitech G510 in very good condition"
11:05:19 <Ysjoelfir> I somehow doubt that, judged by the pics
11:20:10 <TheDude> washing that shit would yield this guy a better return
11:20:28 <TheDude> it just takes some patience to pop all of the keys off
11:20:51 <TheDude> and then washing it is fairly easy afterwards
11:24:35 <rust_collector> MORNING?!!?
11:28:05 <rust_collector> oh good, warning labels
11:28:25 <T3sl4> good mournin rc
11:30:32 <Ysjoelfir> mornings
11:32:01 <rust_collector> må kun tilkobles jordet stikkontakt. NUR ZUM GEBRAUCH MIT GERÄTEN NACH EN 60950 Do not swallow, do not insert inside body, do not use in bathtubs, pools, or microwave, keep away from children, animals, and humans.
11:32:14 <rust_collector> hey
11:32:46 <Ysjoelfir> that sounds very enjoyable
11:33:00 <rust_collector> oh yes
11:33:04 <T3sl4> at my chat window size, "do not insert inside" appears directly above "children"
11:33:36 <Ysjoelfir> lol
11:33:58 <rust_collector> I stole a couple of 12v 9a power bricks. I guess I can if nothing else use them as a battery charger
11:36:19 <rust_collector> I just like reading warning labels, different things are important in different places, it seems
11:37:46 Quit: coppice_ ([email protected]) Quit: Konversation terminated!
11:38:35 <Ysjoelfir> indeed^^
11:40:24 <T3sl4> and the assortment of regulatory logos
11:43:16 <rust_collector> iram, safetymark republica argentina "S" ul, tüv, pct, ce, ccc s&e spiky thing, n322 nsw24192, PSe, nyce, NOM!, no wheelie bin, house. and 10
11:44:46 <T3sl4> i hope all my food is rated NOM!
11:45:34 <rust_collector> oh, ans the motorola logo. then at the bottom, it says astec power, and on the other end, it says emerson (laguna)
11:45:48 <rust_collector> is emerson some testing place, or do they make things?
11:54:04 <rust_collector> hmm, it is not often I pop open a larger than normal laptop power brick, and it has a heat sink on the transformer, and thermal pads on the capacitors
11:54:07 <Ysjoelfir> looks to be an ATM in the philipenes https://www.google.com/maps/place/BPI+Emerson+Laguna+ATM/@14.25204,85.202885,3z/data=!4m8!1m2!2m1!1semerson+laguna!3m4!1s0x33bd7d46b2a1cb71:0x2a16b32e6409caa!8m2!3d14.25204!4d121.06226
11:54:40 <rust_collector> facials and booty shop, nice
11:55:48 <T3sl4> heh, at least they're paying attention to thermal management especially for capacitors
11:56:05 <T3sl4> the big stinker is the ABS case, terrible conductivity
11:56:29 <rust_collector> either that, or they just want something sticky , so they don't burst so quickly
11:57:04 <rust_collector> yes, these things do heat up a bit when you charge allthethings at the same time
11:58:27 <rust_collector> But I do not think I have seen a smps with a heat sink on the transformer before
11:59:03 <rust_collector> with stuff printed on it, so if you look quickly, it looks like it says "best before293283743823928"
12:02:27 <rust_collector> ok, did anything interesting happen here today?
12:04:51 <rust_collector> what would be a 2 leg to220 component, labeled as fb?
12:06:07 <T3sl4> a diode with a ferrite bead on it? :P
12:06:42 <rust_collector> mmkay, yes, that looks right. it has a little bead on each leg
12:10:35 <rust_collector> I am still wondering about that facial clinic and booty shop.
12:14:31 <T3sl4> maybe the power supply is implantable
12:14:36 <T3sl4> people like weird shapes sometimes
12:14:58 <rust_collector> yes, I heard something about that on the internet
12:16:27 <T3sl4> wow, that was a hell of an FTL run. 5992 score in the rock B. i was two drone system points short of a 100% complete system upgrade. plus several extra dives in the final sector, just to flex on the enemy fleet
12:17:05 <rust_collector> eeh, ok, party party
12:17:05 <T3sl4> 117 jumps in total, which was a new crew record i guess?
12:17:22 * T3sl4 pops a cork of space-champagne at rust_collector
12:18:31 <rust_collector> right on my shoulder. that was impressive
12:30:38 <arch> hey, so the uc3843 has a 1A mosfet gate driver. for low current applications, couldn't you just power the flyback primary directly from the output pin? i mean, it would obviously have to be for very low current applications
12:32:59 <T3sl4> if you dont mind it clamped to +V, i guess
12:33:38 <T3sl4> have to run it open loop i.e. run IS from RtCt
12:44:21 <rust_collector> https://www.youtube.com/watch?v=DLqX8_T3BoI
12:53:06 <T3sl4> oh god the distortion
12:53:55 <arch> hmm, i'm having trouble figuring out why all these datasheets use 150kOhm and 100p RC parallel between comp and feedback, for the UC3843. no matter if i pick TI or OnSemi or any other brand, it's always the same two values: https://i.imgur.com/qTw0l1j.png
12:54:19 <arch> even with diff output voltages
12:54:38 <arch> 5V, 12V, doesn't matter. they still use those two values connected bw comp and feedback
12:56:53 <arch> welp, whatever, i can tinker with those once i build it. ill put em down without knowing for the meantime
12:59:57 <T3sl4> because they're doing virgin R||C compensation with shitty regulation, not chad R+C with stable output
13:00:59 <T3sl4> shit nmos symbol too
13:01:23 <arch> man why you always got something negative to say
13:01:30 * arch resists pulling out tupac meme again
13:02:06 <arch> alright fine, i'll make it R+C comp, sensei
13:02:30 * rust_collector considers finding some evil-E meme
13:02:38 <arch> although, i would like to compare how well it performs against R||C comp. maybe for next version
13:04:26 <T3sl4> not hard to analyze. the R gives shit regulation. the C does the same thing a C alone does, it just has an easier time because the max loop gain is shite
13:05:15 <T3sl4> consider the voltage at the FB pin is always 2.5V in regulation: depending on load, CMP might vary 0-5V say, so whatever that does into the FB node, is the opposite of what the output does
13:05:23 <T3sl4> so the uh
13:05:27 <arch> well, for you it's not hard to analyze cuz you've done this a bazillion times. i literally have to spend 10 times reading the same page on the TI appnote https://www.ti.com/seclit/ml/slup340/slup340.pdf
13:06:09 <T3sl4> 5V at 150k into a bit under 3.6k and 16V into 20k, is a variation of what, 5V/7.5 at the output?
13:06:20 <T3sl4> assuming VCC is output, which if it isn't is even weirder
13:06:23 <arch> i've been drilling 1 or 2 pages per day. slow, steady progress :D
13:06:48 * T3sl4 puts arch's pages on a drill, gives it a spin, and makes a mess of loose paper
13:07:33 <T3sl4> maybe it's time to check out some real classes, like uh, random indian yt vids, or legit MIT or other lectures, etc
13:07:56 <T3sl4> if you're not spotting the above, do more homework on opamps and stuff?
13:08:09 <T3sl4> and control theory, just having a theoretical basis for it, is probably worthwhile
13:08:38 <MrMobodies> Hello
13:08:46 <T3sl4> control theory i don' t know how they'll be covering it, the exact class i had was dumb, of course me being me that wasn't a problem but i doubt most of the class really got it :/
13:08:57 <T3sl4> so, YMMV
13:09:02 <rust_collector> oooh, what is the name of those things people had in offices before, that you had things like phone numbers and stuff on, that had a lot of cards, that you could flip thru. Now I want a motorized one of those
13:09:15 * T3sl4 rolodexes rust_collector

13:10:02 <rust_collector> motorolodex
13:11:05 <arch> speaking of indian youtube vids, that's exactly how i learned the purpose of slope comp
13:11:10 <T3sl4> bahaha they dotted everything except the primary winding?
13:11:11 <arch> slow steady progress
13:11:59 <arch> big deal, they forgot the phasing dot
13:12:17 <T3sl4> uuuuuuuuuhhhhhhhhhhhh, that sch doesn't start up
13:12:25 <T3sl4> it just cooks C3
13:12:55 <arch> wtf
13:12:57 <arch> i just noticed that
13:13:05 <arch> lol
13:13:18 <arch> i guess i really shouldn't be paying much attention to manufacturer appnotes...
13:13:19 <T3sl4> did i ever show the sch of this btw? https://www.seventransistorlabs.com/Images/100WPowerSupply24V.jpg
13:13:36 <arch> nope, link it
13:14:22 <arch> why do you have volume of a cone equation up there? out of place :D
13:14:24 <T3sl4> https://www.seventransistorlabs.com/Images/Universal_One_Switch_PSU_Schematic.pdf
13:14:57 <arch> this is a fun game for engineers: spot the typo on the schematic
13:15:17 <T3sl4> arch: don't remember if that was actually for something, or just a challenge problem i was working out
13:16:38 <T3sl4> also on their sch, i'd use a smaller R7
13:17:40 <T3sl4> also, what the /fuck/ is R1 doing? it should be a lot smaller, and in series with D8 sure, but it's not even in the right place to make a join with the C3+R17 node
13:18:16 <arch> you have 3 0.1ohms in parallel, that prim getting hit with near 10A peaks?
13:18:27 <T3sl4> nah bruh, that's just whatever
13:18:27 <arch> sorry more like 30
13:18:29 <arch> oo
13:18:42 <T3sl4> btw the sch i made is for flyback, 1 sw forward, whatevs
13:18:47 <T3sl4> insert parts values as needed
13:19:11 <T3sl4> that's why there's a D10 and a D8, and also for HV output there's a sec aux winding + D9
13:19:37 <T3sl4> think i don't usually use Q2, just jumper over it or something, or over R11 and res over Q2
13:20:01 Quit: TheDude ([email protected]) Ping timeout: 121 seconds
13:20:05 <arch> i see you used R+C comp, but instead of going to ground, why does it go thru a 10k resistor and 1k resistor to gnd?
13:20:22 <arch> so R13 and R1
13:20:53 <T3sl4> i still have a stack of those PCBs BTW, you want a few?
13:21:41 <T3sl4> R1 or R24 is load for IC3
13:21:58 <arch> i would probably have to buy the parts tho and wind the core. too much work for noob. i need to get motivated first hehe. ill let you know after this project
13:22:14 <T3sl4> or also, one of D2 or D6 or both might be needed, just another option
13:22:29 <T3sl4> D3 and R3 most likely exclusive

13:24:19 <rust_collector> put 2 servers in series?
13:24:20 * arch accidentally drops T3sl4's tray of ETD cores
13:24:32 <T3sl4> do what bich, i got two more
13:24:52 <arch> servers? are you living under a rock rust_collector? everything these days is cloud. AWS, google cloud, azure and all that shit
13:25:00 <rust_collector> nope
13:25:22 <arch> well, i must admit, i kinda miss my old work where i got to tinker with physical machines
13:25:22 <rust_collector> some people actually run the cloud
13:25:42 <T3sl4> machines are nice
13:27:31 <arch> alright, guess i'll start off by copying chunks of that schematic
13:27:59 <arch> actually, i just have to copy the opto part and the R+C are placeholder values
13:45:13 <arch> T3sl4, is that a line filter module in the pic?
13:45:24 <arch> everything comes inside it? handy af
13:45:25 <T3sl4> it's several things
13:45:37 <arch> no need to bother calculating line filter values. what a time to be alive
13:45:46 <T3sl4> well, selection
13:47:17 <T3sl4> note there's still a filter onboard
13:47:33 <T3sl4> i put extra filtering in that just because; it's pretty quiet on my test bench IIRC
13:48:07 <T3sl4> what you can't see, is a toroid with a bunch of turns of the brown/gray wires to the output, and another Y cap to chassis
13:48:37 <T3sl4> and yes btw the foil tape grounds the transformer core to chassis, more or less
13:49:13 <T3sl4> also also, see the blue caps on the left side, you won't find those on the schematic
13:49:24 <T3sl4> or, maybe the film cap but it's too big for the footprint

14:20:57 <Halcyon> Heh
14:25:51 <arch> T3sl4, for the optocoupler in the schematic, why not take the Vref at the collector? you used the VCC of the UC3843 going into the collector. wouldn't this cause higher power losses?
14:26:31 <arch> by vref i mean 5V at the collector, instead of the UC3843 Vcc
14:27:09 <T3sl4> 43 doesn't need as much voltage, that's fine
14:27:42 <arch> hmm, so this is what i think: https://i.imgur.com/NhPTu4W.png
14:28:09 <arch> would that work?
14:28:19 <T3sl4> probably i didn't put in VREF because it's not a big deal, but yeah that can be done
14:28:24 <arch> kewl
14:32:18 <arch> sooo this is somewhat funny, i spent half the time to make my schematic look pretty :D
14:32:51 <T3sl4> \o/
14:32:53 <arch> i'm kinda ocd about schematic looks
14:33:32 <arch> if i notice something is uneven, i have an extreme urge to correct the spacing...it's actually bad sometimes. gives me anxiety

21:14:09 <Ampera> Here feminism and feminist is just a term that has lost all meaning. It's like a ball people kept fighting over, it's in the neighbors yard now and nobody gets to play with it
21:14:53 <Ampera> It used to refer directly to distinct women's rights movements in antiquity with semi-defined leadership and notable historical events, now it's an outdated amorphous collective
21:19:40 <hsn> in here there is lots of women who says we are abused even if they live like queens .. so u can imagine this x that = karen
21:20:00 <hsn> ofc there is abusment .. the whole sociecty is shit :D
21:29:18 <Ampera> I can make no accurate comments to your society, I lack the details necessary to.
21:29:29 <Ampera> All I know is Arabia and much of the middle east does not have a good reputation here.
21:31:35 <hsn> Ampera, so i dont have good reputation in ur mind
21:31:36 <hsn> :(
21:31:50 <Ampera> I meant in the context of rights for women.
