00:59:13 <MrMobodies> This bit: "'This was a simple case of human error..."
01:00:29 <MrMobodies> Sounds to me like a case of common sense out the window, laziness, impatience and witchhunt.
01:01:18 <MrMobodies> Maybe wouldn't be a bad idea for customers to start filming themselves wherever they go so when they are accused of stealing they don't have anything to worry.
01:01:45 <K> that is wrong approach
01:01:58 <MrMobodies> oh, the filming themselves?
01:02:06 <MrMobodies> or what the store did with the AI?
01:02:26 <K> well, both are wrong, but each differently
01:02:50 <K> you should not be made to provide evidence of not doing anything wrong
01:03:09 <K> and ai shoud not be used for surveilance in fucking shops
01:03:11 <MrMobodies> if someone has compelling "evidence" against me and i have none proving otherwise, I could be the looser.
01:03:24 <MrMobodies> oh okay
01:06:52 <MrMobodies> I wonder if this is the real system they have going on there... Manager: "Here's your AI, if you don't identify and catch an xx amount of shoplifters in a day we'll penalize you. Catch over these amounts and we'd award you for a bonus to help stamp out crime."
01:07:15 <MrMobodies> oops "if you don't use it to catch..."
01:08:53 <MrMobodies> I imagine one day they'd go after shoppers for putting things back on the shelves or fridges when they change their mind and swap it for somehting else.
01:10:02 <MrMobodies> "you contaminated the food with your finger prints or you let it defrost for 10 seconds."
01:11:30 <MrMobodies> "it also costs us everytime you open that fridge and then refridgerate the product when you could have made your final choice there"
01:12:17 <K> "'how about you get fucked, eh?'"
01:12:25 <MrMobodies> "If was not for 'a small amount of customers like you' we could be achieving net zero by now.... you're not welcome back."
01:13:21 <MrMobodies> K. yes directly put. Dare the shoppers say that and they'd be accused for a whole host of things, aggression. swearing. verbal abuse... etc.
01:13:45 <K> "why you drag your feet?!?!?! tiles cost money!!!!!"
01:13:47 <MrMobodies> frightening other shoppers, destroying the mood.
01:13:51 <MrMobodies> oh yes
01:17:06 <MrMobodies> "Dare elderly walkers, you're getting in the way of more important people needing to get by and affecting our flow through the tills..."
01:17:32 <MrMobodies> "If you don't move out for other's we'll take a few point of you 'loyalty card'"
01:17:39 <MrMobodies> oops your
01:20:57 <MrMobodies> "our policies are very positive, improves shopping experience, improves checkout flow thereby improving customer experience, allow supermarket to run efficient, tackles theft and fraud economocally with fewer staff, thereby free room for more shoppers..."

02:06:28 * arch stares intensely at K
02:09:56 <K> go fix the old psu
02:10:17 <arch> i would, if i didnt have to work
02:10:18 <arch> cant wait for spring so i can dig out some stumps and roots for the row of hedges i chopped down
02:10:51 <arch> well, before i do that, i'm gonna nuke that row with a couple applications of glypho so i encounter no resistance from newly growing sprouts
02:12:45 <arch> maybe ill use my 6 inch auger to help me, but im scared i might destroy a sewer pipe or underground electric lines. would be a rather shitty or shocking experience, respectively

02:33:53 <arch> quick question. so when we have a FPWM: forced PWM mode (aka FCCM: forced continuous conduction mode) buck converter, it essentially allows the low side mosfet to be able to DRAW current from the output capacitor, in order to keep the inductor's current from going to 0, this results in lower current ripple. do i understand that part properly?
02:34:48 <arch> DHess_US, or T3sl4 or Kuschelpony if you get a chance :D
02:35:24 <Kuschelpony> arch?
02:35:40 <arch> hi Kuschelpony, i was just asking about my thought process. if it was correct thinking or not
02:35:45 <Kuschelpony> ah ok
02:35:54 <Kuschelpony> sorry, im very tired from a bad night
02:36:00 <arch> ooh np, take it easy
02:36:39 <Kuschelpony> hmm, your forced PWM will not reduce the ripple, but actually increase it on low load
02:36:44 <arch> sorry i misphrased that last bit: i meant that the lack of the inductor current being zero results in lower VOLTAGE RIPPLE on the output
02:36:55 <Kuschelpony> no
02:37:06 <Kuschelpony> the inductor current DOES drop to zero and even negative
02:37:26 <Kuschelpony> the peak-to-peak current ripple stays approximately constant
02:37:27 <arch> ah, yep, i meant it does not stay at 0 after dumping its energy and go into DCM
02:37:59 <Kuschelpony> what you have appears worse than DCM, but it might have benefits about transient regulation
02:38:26 <Kuschelpony> better you aak me again tomorrow
02:38:29 <Kuschelpony> ask
02:38:43 <arch> sure, or i'll bug T3sl4 when he's around
02:39:29 <arch> actually what i will do is organize my thoughts a bit better and write a new question
02:52:56 <arch> i was thinking of making a low wattage PSU for the 5150, powered by 19V or 20V laptop power bricks. my plan is, it would use off-the-shelf coupled inductors (SRF1260/SRF1280, etc), to generate the +/-12V rails (1:1 coupled inductor operating in fly-buck mode; +12V @ 2A, -12V @ 0.4A --> with a negative linreg to make -5V @ 0.1A); synchronous buck controller driving external mosfets for the 5V @ 7A
02:54:05 <arch> unless...let me see if TI has buck conv ics that can take 24V input and output 5V at 7A or greater. im sure they do. that would simplify things as well.
03:00:23 Join: Kuschelpony ([email protected]) to #EEVblog
03:11:05 <arch> hm, yes, they have some drop-in ics that can handle it. 93% efficiency synch buck ic, 19V->5V @8A. good stuff.
03:17:49 <arch> doh, i forgot i had a bunch of coilcraft MSD1514 series. that will be even better

03:25:45 <Nothing\> interesting
03:25:57 <Nothing\> Colonel Sanders shot and killed a man
03:26:19 <Nothing\> keeping in mind that his title of Colonel was a Kentucky Colonel, which is a lawyer, not military.
03:27:53 <Nothing\> I guess before food, he ran a Shell Gas station and got the brilliant idea at the time of advertising with signs painted on the sides of barns. Being ruraly KY, literally every sign gets shot up until it's unreadable. So, he figured nobody would want to shoot a barn with animals and people and a pissed off farmer with a shotgun inside potentially
03:28:52 <Nothing\> Then his competitors started paying the farmers to paint over the advertisements. So one day while 2 Shell execs were visiting, he caught wind that a farmer was painting over one of his ads, so he went over there with the execs.
03:29:52 <Nothing\> a fight ensued and one of the competitors shot and killed one of the Shell executives. Prompting The Colonel to open fire and kill the man, whihc was found to be self defense in the courts.
03:30:23 <Nothing\> Funny post script to the story is the guy who shot and kill the Shell executive was assasinated in prison by the executive's "associates"
03:32:02 <arch> simplest, but not exactly most optimized method, but easy for diying: 1 high current buck regs to make 5V @ 7A rail, and 3 low current buck regs to make the 12V, -12V, and -5V rails. yep, that's what i'm gonna use. i already have a whole lotta TPS562201 and i ought to use them up first before potentially considering buying newer buck ics
03:49:29 <K> welp, mom is gone.

04:24:06 <K> thanks
04:38:21 <arch> hmmm another offtopic question. is it always better for a multi rail psu, like 12V, 5V, -5V, -12V, to power up from highest to lowest voltage rail?
04:38:37 <arch> rail sequencing in other words
04:42:42 <K> internets say "all together", but there is supposed to be "power-good" circuitry that enable CPU and then POST
04:42:48 <K> if i read correctly
04:46:51 <arch> well, yes, all together because the 5150 psu is a flyback trafo. if im gonna use separate buck convs, each will have diff capacitance and inductor requirements, so they will start up not all at once. so in that case, easiest way is to feed the EN pin with RC delay. 0.1uF, 0.2uF... etc etc, to stagger startup
04:48:29 <K> no luck fixing old psu?
04:50:12 <arch> haven't looked at it other than clean the dust out with air compressor
04:50:21 <arch> i took it out and opened it up
04:51:27 <arch> at a high level, here's what im thinking. lmk what you guys think. it will use a standard 85 or 90W, 19V-20V power adapter, like for laptops or thinkpads: https://i.imgur.com/qZOys84.png
04:53:47 <arch> that's roughly $5-6 in buck reg ICs alone lol. im planning on making it on copperclad pcb, DIY style
04:56:12 <arch> i need you guys to convince me to fix the psu rather than me spending a couple dozen bucks and time to DIY it lol
05:11:14 <rust_collector> you need to just find a normal ready made thing that does what you need, then use it
05:18:43 <arch> b...but..that's no fun tho
05:19:12 <rust_collector> yes

07:28:57 <K> master cheeks eh
07:29:35 <rust_collector> master cheeks... that sounds nice and both racist and pervy enough
07:29:37 <arch> ooh led chaser... are you a knight rider fan?
07:30:20 <Kuschelpony> no, but more in a mood for an circuit design puzzle (when im in the next long train travel again)
07:56:59 <arch> so i opened up the psu, and closely inspected all electrolytic caps. i can't see any bulging (OwO) or leaky caps. what i do notice are a handful of relays in there as well. so im going to first blow this with compressed air to clean out the dust, then i'll power up the 5150 with it again and listen closely to the clicking
07:58:14 <T3sl4> i wouldn't expect to see them bulging or leaking but they could be dry. measure to be sure
08:00:04 <arch> eh? but measuring them is a lotta work tho, gotta get my vacuum desoldering gun and take it out and do all that :|
08:00:11 <arch> lcr meter stuff
08:00:15 <T3sl4> pfft
08:00:22 <rust_collector> oh no! effort!
08:00:29 <T3sl4> if the ESR or |Z| is low enough in situ it's probably fine
08:00:50 <rust_collector> it is probably better to design 12 versions of a diy switching thing

08:55:45 <MrMobodies> Corrosion gone but the issue seems to be with the prongs spreading out on the dc connector
08:56:49 <MrMobodies> I wonder why do they have those STUPID prong like things in those connectors. I find I occasionly have to use a tweezer to squeeze them in sometime. I replaced with one that I never have problems with.
08:57:11 <MrMobodies> Prong like things in the DC plug squared in red bottom right.
08:57:47 <MrMobodies> always experiencing connectivity issues with those but never the ones that have a barrel shape inside
09:07:22 <K> if it had corosion inside it i would consider either replacing them (both sides), or at least washing thoroughly
09:07:59 <MrMobodies> I changed the DC connector
09:08:07 <K> ah ok
09:08:15 <MrMobodies> oops I mean DC plug with the prongs in it
09:08:22 <MrMobodies> the DC connector I unsoldered
09:08:25 <MrMobodies> couldn't find a spare one
09:08:32 <MrMobodies> so put it in vinegar
09:08:55 <MrMobodies> and this whiteness appeared
09:09:13 <MrMobodies> dipped it in alcohol for a while
09:09:17 <K> zinc reacting with acid in vinegar i think
09:09:19 <MrMobodies> and it seem to come out clean
09:09:22 <K> yeah

09:12:52 <MrMobodies> and green bits that never came off
09:13:00 <MrMobodies> so I replaced it with something a it better
09:13:34 <MrMobodies> a barrel jack with the full inner - surface covered in metal
09:13:42 <MrMobodies> instead of the stupid daft prongs in the other

09:20:55 <MrMobodies> Every now again even on the good LiShin have this stupid connector and after time or movement, the appliance would go on and off as the plug wiggles
09:21:10 <MrMobodies> I notice the prongs really push into the plastic
09:21:26 <MrMobodies> so by using a treezer to push them in it locks in place for a while
09:21:33 <MrMobodies> I wonder why such a stupid design
09:23:00 <MrMobodies> Left: DC plug with inner prongs. Right: DC plug with inner barrel.

10:07:53 <Casper> Hi there, I have a weird issue... I'm trying to build a wheel sensor replacement circuit. The sensor is a 7/14mA type, and the supply is 8-16V but can go quite higher, with a temperature of -20°C to like 60°C+.... It need to switch between the two current via an optocoupler/isolated from the microcontroller. Best way I found so far to not deviate from the 7/14 is to use a TL431 in a constant current mode, but it feels wrong, plus part of th
10:07:53 <Casper> e current is unaccounted so still vary a tiny bit. Does anyone have a better idea?
10:11:30 <Halcyon> Most of the EE nerds here are from the UK and US, some of the US people might still be around if you stick around for a bit.

10:22:27 <electrohead> (I run that domain, looks scary but really isn't)
10:23:33 <electrohead> For your question, hrmm. I don't know enough to answer that honestly, someone else will have to step in
10:23:54 <electrohead> Also, nice nick ;p
10:25:48 * steve30 meows at the empty coffee cup
10:27:30 <Casper> I'm sure the pictures don't do justice to your guitar, because to be fair, it looks very bad to me... I mean rinkles everywhere on the case fabric, and looks like a 3d printed body guitar that they didn't fully sand down yet... lol sowwie :D
10:28:41 <Casper> but yeah, for my question... it seems to be a weird special case for sure
10:29:10 <Casper> it's like it have all the possible constains... also, kinda space limited too
10:38:19 <electrohead> "looks 3D printed" - this is amazing. I'm going to print this out

10:39:04 <electrohead> :p
10:40:09 <electrohead> Serious though, check out the BTB805MS - far from your average guitar. The multi-scale fretboard is just fascinating
10:40:41 <arch> Casper, have you considered the LM334? look on page 8 of this: https://www.ti.com/lit/ds/symlink/lm334.pdf do i understand you're looking for a really accurate current source that you can switch between 7mA and 14mA via optocoupler?
10:50:54 <arch> i think the easiest option i can think of is...you have a default resistor (fixed), and to switch between 7mA and 14mA, you simply activate a mosfet output optocoupler. the resistance of the mosfet will be marginally changed by temps. ex: https://www.ti.com/lit/ds/symlink/isom8600.pdf
10:55:28 <arch> jfc electrohead, that's an expensive guitar
10:56:00 <electrohead> Would you be surprised that's not my most expensive guitar?
10:56:24 <arch> honestly? no. you got some high tech stuff and your lab especially
11:00:51 <electrohead> lol

11:01:17 <electrohead> Ibanez RG2228GK - Dino Cazares of Fear Factory has used this exact model in the past
11:01:29 <electrohead> This is an amazing machine
11:01:39 <arch> oooh, fancy box. the guitar is nice too, i guess
11:01:43 <electrohead> xD
11:01:54 <electrohead> At least this box has no wrinkles in it
11:01:59 <arch> \o/

11:02:57 <MrMobodies> and them calling the decision stupid
11:03:35 <MrMobodies> with one of the original Youtube founders now Reddit said "If enough people say it then it probably is true"
11:03:57 <MrMobodies> Same thing here, with people being turned away from their GP surgeries

11:04:22 <MrMobodies> they seem to class as abuse
11:04:42 <MrMobodies> if they were turned away abruptly needing medical help
11:04:52 <MrMobodies> No smoke without fire.
11:04:59 <electrohead> arch, lol
11:05:21 <MrMobodies> so many medical centers, with poor 1 star reviews complaining of it.
11:06:12 <MrMobodies> I don't remember that happening before I moved, patients just walked in and were seen to. No appointment if urgent just a long wait. Never turned away
11:06:27 <MrMobodies> Isn't that bad.
11:08:16 <electrohead> arch: what if I sang like this, instead? (nsfw?) https://www.youtube.com/watch?v=O8kGgtF-C4w

11:10:02 <MrMobodies> I see it has Superman in it
11:12:34 <arch> lmao terminator reference

11:14:34 <arch> !rimshot
11:14:34 <EEVBot> ba dum tss!
11:15:01 <arch> so random lol. did the guy literally burp the whole song and string em together? :D
11:16:54 <electrohead> he's doing a snort/inhale sort of thing, he talks about it in an interview lol
11:18:13 <arch> kinda reminds me of: https://www.youtube.com/watch?v=09LTT0xwdfw

11:18:51 <arch> Doctor: "Say ahh"
11:18:51 <arch> you: " OW AH AH AH AH"
11:18:51 <arch> Doctor: "It appears you are down with the sickness"
11:18:59 <electrohead> lol
11:39:02 <Casper> arch: oh looks nice at first glance, will check that more for sure
11:43:24 <Casper> second glance is scary, they talk about using it as a thermometer :D third glance look good sooooo might be the winner
11:43:29 <Casper> thanks
11:44:31 <Casper> arch: do you know if any diode is fine for the temp compensation or does it have to be specific?
11:50:08 Join: Kuschelpony ([email protected]) to #EEVblog
12:08:37 <arch> Casper, it's there on page 9: "The recommended diode for use in this circuit is the 1N457 because its tempco is centered at 11
12:08:38 <arch> times the tempco of the LM134, allowing R2 = 10 R1"

12:09:15 <Ampera> both are stock 5150's with a CGA card
12:09:56 <arch> ohh a demoscene program
12:09:59 <arch> you could find other reputable schematics online to see if a different diode can be used, but the 1N457 is still available today for cheap: https://www.digikey.com/en/products/detail/onsemi/1N457/975883
12:09:59 <EEVBot> [url] Just a moment... | www.digikey.com
12:10:19 <arch> im sure the 1N914 or 1N4148 can also be used. those are all pretty similar small signal fast diodes
12:11:44 <Casper> arch: yeah, but planning to get the board made at jlcpcb, which is low on that diode
12:12:10 <Casper> also an extended part
12:12:14 * Ampera hugs T3sl4
12:12:31 <Casper> will check in more detail tomorrow
12:12:41 <arch> if LMGTFY was still around, i would point you to: https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/345270/smd-alternative-for-1n457-lm334-current-source-minimizing-tempco

12:12:57 <arch> gotta use that google fu my friend
12:14:00 <arch> " the tempco is also (exponentially) related to the forward current. My current source will be 0.7uA so my tempco will be around 2mV/degree instead of the 1.43 @ 1mA" i can vouch for that, i've tried it myself, but with 1n4148
12:14:19 <arch> and using a hot air gun to blow 100C hot air
12:17:50 <Casper> thanks I'll check all that in detail tomorrow with a fresh mind :D
12:18:12 <arch> cool
