00:21:19 * Zsjoelfir eats all of electrohead 's licqourice
00:21:28 <Zsjoelfir> I have to get you new ones for your package xD
00:21:56 <+electrohead> you really ate them? lol
00:24:36 <Zsjoelfir> yes. 2 of 3 packs
00:26:33 <+electrohead> I imagine they taste good :p
00:32:07 * T3sl4 lick-ors Zsjoelfir and electrohead

00:39:59 <K> i take sugestions for switchmode ic for making 250mA +10/-10 with minimal component count
00:40:25 <T3sl4> from?
00:40:41 <Kuschelpony> so 5 Watt ?
00:41:05 <T3sl4> input?
00:41:14 <T3sl4> thank you electrohead
00:41:19 <K> 5V
00:43:21 <T3sl4> any of those 1-2A SOT23-6 parts should do
00:43:59 <T3sl4> get like, two coupled inductors, wire primaries in parallel as boost, but cap couple them to the secondaries for a SEPIC + and Cuk - output
00:44:03 <T3sl4> take feedback from +out
00:46:11 <K> mm
00:48:06 <Kuschelpony> you can also see that as augmented flyback
00:48:55 <flyback> BMCC
00:56:12 <K> example part number for that sot23-6 part?
00:58:30 <K> was looking at this before - https://www.analog.com/media/en/technical-documentation/data-sheets/1945fa.pdf

02:14:36 <K> no opinion on LT1945 ?
02:21:30 <rust_collector> nope
02:21:58 <K> crusty
02:22:12 <rust_collector> that is your opinion
02:23:49 <K> yes.
02:28:52 <T3sl4> i mean i'm sure it's fine, but why would you want it? :P
02:36:36 Quit: Guest69 ([email protected]) Quit: My MacBook has gone to sleep. ZZZzzz…
02:38:14 <K> as i see it it has a nice datasheet
02:40:26 <T3sl4> fine, then go be a rich bastard!
02:40:33 <T3sl4> wanting quality components, pfft
02:43:24 <K> (cries)
02:49:39 <DHess_US> Go read some of the application notes on how to generate dual supplies. Most use a coupled inductor but not all, and there are special requirements for it to work.
02:50:18 <K> the lt one does not need coupled inductor
02:50:32 <K> but i will look it up
02:51:16 <K> fwiw it looks like it will be not be possible to reliably power the whole thing from usb
02:51:48 <DHess_US> The LT1945 is just a dual regulator.
02:53:33 <K> i am considering removing the power supply part from the project, having it on a saparate board or just lab supplies for start
02:54:02 <K> otherwise there are too many rabbitholes to fall in into
02:54:26 <DHess_US> I tend to avoid such specialized parts.
02:54:38 <K> why?
02:54:41 <DHess_US> USB power is a rabbitghole just by itself.
02:54:53 <DHess_US> pricing and availability tend to be poorer for specialized parts.
02:55:16 <K> for production i would agree
02:56:53 <DHess_US> I actually consider it a bigger problem for production, because a design using more common parts is easier to adapt.
02:58:19 <K> that is what i meant, yes
02:58:25 <DHess_US> Of course if you need the smallest physical size, then pricing and availability is less important.
03:01:16 <DHess_US> One reason parts like the LT1945 exist is that coupled inductor dual output designs only work in continuous conduction mode, which places limits on output current range.
03:02:46 <K> current range seems to ok for my use case
03:03:37 <DHess_US> I mean they don't work at low output current where discontinuous conduction mode happens. The LT1945 does not have that problem.
03:06:10 <T3sl4> or at least where the main output load is less than the secondary output
03:07:42 <DHess_US> The underappreciated trick and why it works at all is that in continuous conduction mode, the duty cycle is fixed by the input to output voltage ratio. In discontinuous conduction mode, the duty cycle varies with output current.
03:08:35 <DHess_US> Doesn't LT have a single inductor dual output chip?
03:08:46 <DHess_US> It uses the same inductor for both outputs?
03:10:56 <K> nope, 2 inductors
03:21:27 <DHess_US> No, I mean there is such a thing. I'm not sure if LT makes a part intended to take advantage of it.
03:21:37 <DHess_US> It is in an LT application note.

03:29:39 <DHess_US> Figure 6 here, https://www.analog.com/media/en/technical-documentation/application-notes/an29f.pdf
03:33:02 <DHess_US> There is another variation which relies on linear post regulation for lower noise.
03:34:15 <DHess_US> In most cases I suspect it is better to use an inverter, and I think that would be the case with USB also except where input current needs to be controlled.
03:34:47 <DHess_US> Although it is not difficult to control input current on an inverter.

04:06:07 <arch> well, the only downside is, that heatsink is at drain potential, so Vcc :D
04:06:11 <arch> soooo...dont short it
04:06:48 <arch> fking metal tab on the TO-247...why the fuck cant they keep it isolated
04:07:48 <Kuschelpony> arch, because "they" made that large case primarily for best heath dissipation
04:08:18 <Kuschelpony> of course you can also look for components labeled with -F which has an epoxy cover for isolation built int
04:08:18 <arch> yeah, but considering you have to use a thermal pad to isolate it from the heatsink, i think it's a waste of potential
04:08:26 <T3sl4> because your dumbass didn't get the DBC iso version
04:08:29 <Kuschelpony> i dont think so
04:08:43 <arch> T3sl4, nowww you tell me...why is it always after i build a project...
04:08:47 <arch> o well, that's all salvaged parts
04:09:16 <T3sl4> but srs, those are fairly uncommon among MOSFETs
04:09:35 <Kuschelpony> because it leaves the choice to <ME> if i want to mount it unisolated (when the tab is in some circuit at ground potential), fully isolated with compromised cooling, or something in between like a copper heatspreader and then large surface isolated to the final heatsink
04:09:47 <T3sl4> pretty common for TRIACs for some reason?
04:10:14 <T3sl4> or AlN plates, which are also kinda hard to find, probably ebay easy enough idk
04:11:40 <arch> with this, i can finally full load test my 65W sepic with a static load. i was honestly impressed. even at 150W, the temp on the mosfet case, with my ir thermometer, i only saw ~73C ish
04:11:49 <arch> fan was on obviously
04:12:02 <arch> GTX580 power rating was 244W, so i got plenty headroom
04:12:25 <arch> but im not gonna push that mosfet so hard. it's only rated for 120W at 100C tcase
04:13:34 <T3sl4> <evil kermit> run it until it explodes
04:14:13 <arch> the other worry is if i somehow exceed 138C, that bismuth solder's going PLOOP! and then that mosfet is coming right off and burning up instantly
04:14:27 <T3sl4> which btw, if you have the supply handy to run it up that high, isn't a bad idea. you're out a transistor and the time to replace it (oh, and maybe the opamp because gate breakdown, hehe), but you get to plot a real point on the SOA curve
04:14:35 <arch> which, i shouldn't, because i already tested the 100C overtemp shutdown
04:14:42 <T3sl4> sometimes the curves are underestimated
04:15:20 <arch> yeah, that's why i made the opamp on a dip socket muahaha. i always think worst case. sometimes it helps to be a pessimist
04:16:26 <T3sl4> optimistic pessimism ftw
04:16:47 <T3sl4> also, a spring clamp or something to hold it down in case it would otherwise desolder, isn't a bad idea
04:28:53 <arch> initially, i was going to just use the spring clip method, but i was unable to find something on ebay that i could use. so i went with the bismuth solder directly to heatsink route.
04:29:26 <arch> i also tried out the thermal tape method, for fun and science, but the heat dissipation was awful. orders of magnitude worse
04:29:41 <arch> solder has way better thermal conductivity
04:30:24 <arch> the only thing i'm using thermal tape for is that small transistor used for temp sensing

04:32:06 <T3sl4> thermal tape needs to be clamped for a while, it flows very slowly. or needs heat, specifically the phase change stuff
04:33:06 <+electrohead> arch: I love the idea of that, neat!
04:33:09 <+electrohead> and, hey o/
04:34:00 * T3sl4 cuddles electrohead
04:34:19 <arch> hi
04:35:09 <arch> yeah...see, that gtx580 was my very first gaming gpu. i bought it used for $60 off ebay, and it lasted me about a year before it bugged out. then i reflowed it and it lasted me another 3 months before totally dying. but i couldn't throw it out cuz memento
04:35:25 <+electrohead> heh
04:35:27 <arch> so it just gathered dust for 3 years until about 2 weeks ago when i went ahead with this plan lol
04:35:33 * electrohead fondles T3sl4
04:37:48 <+electrohead> arch: you should steal some power from said PSU, and make some blinkenlights or whatever
04:37:52 <+electrohead> light that baby up, lol
04:38:14 <+electrohead> are you using the fan?
04:38:41 <arch> not much power available for it really. that 5V boost stage outputs 10V (ignore schematic that says 12V), and the input current is about 1.7A at 5V, so you need a 10W adapter
04:38:50 <+electrohead> ahh ok
04:38:52 <arch> the fan is really high speed, high current at 12V
04:38:58 <arch> so i dropped it to 10V
04:39:14 <+electrohead> yeah fair enough, you could even get away using lower than that
04:39:31 <arch> yes, it sounds like a jet turbine

04:47:02 <+electrohead> arch: could always whip up a minimal PWM controller for the fan, too
04:47:04 <+electrohead> T3sl4: lol
04:48:31 <arch> yeah, but then you're looking at increased costs, increased board space. the point of this project was to be barebones while having some protection built in (namely, 100C t-case shutdown, which works a treat!)
04:48:51 <arch> and keeping it to just 1 major chip: LM324 (quad op amps--all 4 are used). pretty efficient
04:49:17 <arch> and the hysteresis works nicely too
04:49:36 <arch> so it won't turn back on until t-case drops below ~85C
04:49:44 <+electrohead> well, it's a graphics card after all, I imagine you may be able to find PWM controller hardware already on that board?
04:49:52 <+electrohead> nice :)
04:50:22 <arch> idk if you noticed, but i literally gutted that card. it's missing the brain and most of the parts. i salvaged all the power-SO8 mosfets, and one of them is used for that boost converter lol
04:50:32 <arch> so in a way, the card lives on
04:50:38 <+electrohead> yeah I noticed that lol
04:54:58 <arch> damn i am some cheap fucker. i even salvage power-SO8 mosfets :D
04:58:18 <+electrohead> I salvage everything I can, don't feel bad :p

05:34:57 <arch> kiska, i feel like people aren't throwing out as much stuff these days that can be salvaged for parts
05:41:01 <arch> BGA and really tiny smd parts make it not worthwhile to salvage parts
05:41:34 <arch> i will salvage sot-23-6 smps ICs and regulators whenever possible though
05:46:47 <+electrohead> I have a metric fuck ton of parts, through-hole and SMD
05:49:03 <arch> salvaging iron powder toroids, and any smd inductors that are 1210 sized and above, you'll save the most amount of money. cuz inductors are $2+/pop
05:49:16 <arch> unless you buy from china
05:55:07 <Lord_of_nothing> omg now 1tb micro sd cards are avaiable
05:55:24 <Lord_of_nothing> even the 512gb cards got very cheap

06:55:01 <Some_Person> When I was looking last year, 400GB was the obvious sweet spot for price vs size for microSD. Don't know if that's still the case.
06:55:44 <Ampera> I've bought uSD cards from Amazon before and have never had a problem
06:55:52 <Ampera> just make sure it's sold /by/ Amazon, or by a known manufacturer
06:56:00 <Some_Person> Same here
06:56:06 <Ampera> I usually stick to Samsung and SanDisk. Silicon Power on occasion
06:56:10 <Some_Person> Sold by Amazon seems to be fine, third-party sellers can be iffy
06:56:42 <Ampera> I've seen the scam cards you're talking about, but so long as you're not dumb and understand what stuff is actually worth and what's too good to be true, then it's no problem
07:00:14 <Some_Person> I bought my SanDisk 400GB card last year from Amazon for $44.99 and have had no issues with it
07:15:58 <Ampera> Earlier this year I bought a 512GB Samsung card for 75.59 and it's still in my phone
07:16:02 <Ampera> my phone which has 1TB of storage now >:D
07:16:11 <Ampera> in other news, pizzas have been ordered, going to pick them up in about 20 minutes or so
07:16:35 <Ampera> we got three 18" pizzas, one with mushroom and ham, one with sausage and pepperoni, and one with meatballs and pepper
07:16:48 <Ampera> they have decent prices for pizzas too, those three pizzas were just a hair over 60 dollars in total
07:17:09 <Ampera> I suppose that's a slight advantage of a place that's cash only, they pass a bit of what they don't have to pay in technology and credit card fees to you
07:17:35 <Ampera> It's also a good way to break up my 100 dollar bills people give me on occasion into more useful notes without having to go to the bank

10:17:49 <Nothing\> huh, my printer won't scan money (obviously) but it scans these "duty paid" stickers off of cigarettes and legal weed without any problem
10:18:14 <Nothing\> although there's a hologram on them, so wouldn't get that. But with money it just flat out refuses to scan it or do anything with it
10:18:20 <steve30> hehe
10:18:26 <Nothing\> apparently photoshop won't even open images of money for editing
10:18:27 <steve30> my scanner scans money fine :)
10:18:39 <Nothing\> maybe it's just the printing/copying of money
10:19:01 <steve30> I gather some newer scanners/software won't do money, but my old stuff manages fine.
10:19:33 <Nothing\> but i was reading about how the old way they did it was there was a special pattern dubbed the "eurion constellation" where if a copier caught this pattern, it would refuse to copy the note
10:20:04 <Nothing\> but now they apparently have a much more complicated system, which they incorporated the eurion constellation into. Super secret so nobody knows how exactly it works.
10:20:25 <Nothing\> steve30, that's weird
10:21:04 <Nothing\> the way it was explained, it sounded like it was built standard into the software of every single scanner, copier, printer etc. Which does seem a bit far fetched.
10:21:21 <Nothing\> Especially when you get into Chinesium stuff. I really don't think they give a crap about copying money
10:21:53 <Nothing\> though knowing them, they'd probably just rip off somebody else's software and maybe give it a bitty little tweak
10:22:27 <Nothing\> which reminds me, the software on my microwave is becoming increasingly glitchy. It's really weird.
10:23:18 <Nothing\> at first it started with this weird thing where if I depress the button to open the door just enough, it'll turn on the light, the turn table and the fan, but not the magnetron as far as I can tell by the sound of it.
10:23:45 <Nothing\> then last night when I pressed the button to take some foot out, the microwave beeped and the screen displayed a bunch of jibberish until i pressed a button.
10:24:04 <Nothing\> foot's the best part of the cow, you know
10:24:24 <Nothing\> all that tasty tasty glue
10:24:58 <arch> T3sl4, what's considered "out of regulation" for a psu under stress test, like a constant current load? is it a percentage, say 5% below the unloaded voltage?
10:25:37 <arch> yeowch! 106C under 110% load!
10:25:42 <arch> that inductor is toasty
10:25:51 <Nothing\> don't want that
10:26:44 <Nothing\> i dunno how hot the insullation can get. I'm guessing 150c but you don't wanna go melting it or you'll turn your inductor into a jumper
10:26:57 <arch> 109C, ok im stopping the test
10:27:18 <Nothing\> yeah once you can boil water on your electronics, i think that's enough
10:28:32 <Nothing\> lol @ this posting for magnesium turnings on amazon
10:28:37 <arch> well, i designed the sepic for 65W, but i was applying 110% load. let's see if it can handle the rated load of 65W
10:28:47 <Nothing\> With the size of 4.7 in long 3.6 in wide and 1.6 in deep, the tin container keeps mageniusms away form childen, pets, fire, water, etc. Safe and Easy to store and carry in your backpack,BOB, survival kit or car.
10:28:56 <steve30> i should probably go out on the bike
10:29:03 <Nothing\> cuz everyone knows tin containers are completely fire, child and pet proof
10:29:18 <Nothing\> who needs a fancy lock box or proper storage when you've got a TIN CONTAINER!
10:29:59 <Nothing\> i wouldn't want old rex eating up my mageniusms
10:30:09 * Ampera hugs Nothing\
10:30:16 * Nothing\ hugs Ampera <3
10:30:21 <Nothing\> how ya doing buddy?
10:30:33 <Ampera> doing sever maintenance
10:30:41 <Nothing\> sounds tedious
10:30:43 <arch> welp, if this doesn't work out, all i have to do is use my 65W sepic...re-rate it to 50W, and bam, all set lol
10:30:51 <arch> big brains time
10:31:06 <Ampera> not really, I enjoy it
10:31:11 <arch> but yea, that coupled inductor might be getting overheated due to 40% ripple factor
10:31:13 <Nothing\> oh, that's good then
10:31:24 <Ampera> moving some *EMP stack sites from one sever to another
10:31:26 <arch> that's the hottest component on the board
10:31:26 <Nothing\> yeah 40%'s way too much
10:31:30 <Nothing\> you need more caps in there
10:31:42 <Nothing\> or more capacitance anyways, in one form or another
10:31:45 <arch> no..capacitors will not do anything for the inductor ripple factor
10:31:46 <Nothing\> on the output
10:31:52 <arch> you either need higher inductance or higher frequency
10:31:53 <Nothing\> oh, inductor ripple
10:31:58 <Nothing\> yeah
10:32:03 <Nothing\> that won't help much
10:32:22 <Nothing\> well now wait a minute
10:32:23 <arch> actually it might. but im too lazy to redo the calcs and comp for higher freq
10:32:41 <arch> the mosfet is cool as ice. 50C
10:32:45 <Nothing\> so it's rippling presumably because the circuit's oscillating, right?
10:32:59 <arch> you don't say? that's why it's called a switched mode power supply -_-
10:33:11 <arch> T3sl4, talk some sense into this man
10:33:32 <Nothing\> i meant oscillating from the inductance, not the switch
10:33:43 <Nothing\> it's an RLC circuit
10:34:00 <Nothing\> it's gonna want to oscillate at its resonant frequency
10:34:23 <arch> are you pulling fancy words outa the hat again? the problem isnt that, it's the core losses from high ripple factor
10:34:35 <Nothing\> arch, and what do you think causes the ripple?
10:34:38 <T3sl4> buh
10:35:04 <Nothing\> i just said, it's rippling because it's an RLC circuit that's trying to oscillate
10:35:23 <arch> let me see if this can handle 50W
10:35:29 <arch> so 19V @ 2.63W
10:35:34 <Nothing\> arch, god speed
10:35:34 <arch> Amps*
10:35:37 * Nothing\ crosses fingers
10:35:58 <Nothing\> secretly i'm willing the magic smoke to come out lol
10:36:13 <arch> joke's on you, i used a current mode controller. can't happen
10:36:24 <arch> the inductor saturates at a much higher current than what i designed for
10:36:26 <Nothing\> touche
10:36:32 <Nothing\> that's good
10:36:57 <arch> well, the margin really isnt much though. only about 3A
10:37:04 <Nothing\> i'd like to get a good inductor like that. All of the ones I've gotten are crap
10:37:37 <arch> this is the one i used: https://www.we-online.de/katalog/datasheet/74485540101.pdf
10:37:39 <Nothing\> i've been trying to find one with lots of inductance and little resistance. Guess toroidal ones would probably be my best bet
10:38:21 <Nothing\> i got a couple of coaxial and single axis through hole ones at 100mH, but they have resistances in the hundreds of ohms
10:38:22 <arch> hey wait a moment...that inductor is rated for up to 150C operation, and im seeing 109C, in an open enclosure
10:38:33 <arch> sooo probably will breach that in a closed enclosure
10:38:43 <arch> at 65W
10:38:45 <Nothing\> so any oscillator i try to make with them just has a shit Q factor
10:38:50 <arch> but at 50W it should be nice and okay
10:39:26 <Nothing\> I have a toroid, but it's fucking hard to wrap a toroid by hand, i've found.
10:39:32 <arch> so lesson is, you should use these smallish coupled inductors for power levels around 50W
10:39:48 <Nothing\> Especially if you're using low gauge wire
10:40:19 <arch> you should not bother winding iron powder toroids by hand. just desolder them in bulk from craptons of thrown out atx psus
10:40:22 <arch> they're literally free
10:40:47 <Nothing\> arch: so far all of the PSUs i've cracked have had the toroids epoxied on
10:40:51 <arch> that way you save time, money, and they already come with excellent coupling factors, so you can use them for 2 or 3 winding custom transformers
10:41:08 <Nothing\> i mean i can get them off the board, but then they're still all covered in epoxy with epoxy all in the hole and stuff
10:41:35 <Nothing\> and i heard you can get them from the ballasts from CFLs but the ballast i got was maybe as wide as my pinky
10:41:47 <Nothing\> definitely not the huge toroid i was expecting
10:42:23 <Nothing\> for some reason (probably cuz i never use a real supplier) good inductors have been unusually elusive
10:42:34 <Nothing\> i should probably just check out mouser
10:43:06 <Nothing\> rather pay the extra $20 and get what i want than spend $3, wait 2-3 months for delivery only to find it's garbage
10:43:51 * Nothing\ glares at the pile of breadboards on his table
10:48:16 <Nothing\> mmm it's nice weather outside
10:48:45 <Nothing\> if i weren't so fucking anhedonic i'd take my Switch or 3DS outside and play something
10:49:00 <Nothing\> and probably get eaten alive by mosquitos since this is their prime feeding hour
10:55:51 <jaymax> Yeah that happened to me Nothing\.
10:58:45 <jaymax> Had my redneck fireplace going while I bagged up old asphalt shingles for tomorrow's trash pickup.
11:02:23 <jaymax> One more trashday before the asphalt waste is gone, and dozens of hick-pit campfires before the excess crapwood is no more (probably more than the old grill can structurally handle).
11:02:44 <arch> hmm it seems my PSU can handle 60W so far, 80C temp. let's say it'll hit 90C and stabilize around there
11:04:22 <arch> you know what, i'll just do a lifehack, a la copperclad heatsink strips: https://elog.moltensolderlabs.com/elog/1
11:04:22 <EEVBot> [Title] - Electronics Logs - MoltenSolderLabs
11:04:36 <arch> that should be enough to bring it up to spec for 65W

11:20:14 <Nothing\> i probably should anyways
11:20:39 <Nothing\> although windows' calculator's come a long way since windows 10
11:21:04 <Nothing\> holy shit speaking of which, i just remembered having a dream last night about that whole "windows as a service" thing that microsoft tried to float
11:21:11 <Nothing\> who the hell dreams about stuff like that?
11:21:23 <Nothing\> i'm not even that much of a CS nerd
11:22:59 <Nothing\> i'm not even sure i understand the concept of windows as a service. I think the gist of it was instead of releasing new versions of windows every few years, windows 10 was supposed to be the last version they'd ever release and they'd just continue to add onto it over the years with more service packs and updates and shit. Basically turn it into the world's worst example of bloatware ever.
11:23:52 <Nothing\> doesn't sound terribly profitable either, unless you make it a subscription service. But then you're basically making users pay for security updates and important stuff, too
11:25:17 <+electrohead> heh
11:25:28 <+electrohead> I still remembder how to crash win98 with one command, after all these years!!

11:27:41 <Nothing\> i know it's not quite the same as crashing windows, but you get the idea
11:27:55 <Nothing\> i remember that actually still working back maybe 10 years ago
11:28:35 <Nothing\> but i had to do it in its entirety, ie STARTKEYLOGGER "DCCSEND" 0 0 0
11:28:38 <Nothing\> or whatever it was
11:29:26 <Nothing\> actually that's a shame about what happened to macafee
11:29:36 <Nothing\> there's no worse fate than dying in a hell hole prison
11:29:54 <Nothing\> i don't care who you are, nobody deserves that sort of suffering

11:34:18 <+electrohead> ta-da
11:35:40 <jaymax> Nothing\: Windows 365 likely has the most significant usecase for work-from-home employees in medium-sized companies. They won't have a budget to issue laptops, they cannot trust the state of whatever HW the employee uses (from a security standpoint), but need something the employee can do work on.
11:37:24 <jaymax> So the employee can use their own desktop and remote into something that Microsoft protects the security of.
11:41:18 <jaymax> Ahhhhh. DOS quirks.
11:41:47 <jaymax> Thanks for that, electrohead. oVeR aNd OuT ~~~~
11:41:55 <+electrohead> Remember those days? Lol
11:42:45 <Nothing\> lol electrohead
11:42:47 <Nothing\> i don't miss that
11:42:55 <jaymax> I remember doing discrete stuff between the `ctty nul` and `ctty con` commands.
11:43:11 <Nothing\> i really hate flash drives and such for that reason, actually
11:43:22 <Nothing\> i always forget to properly "eject" them in the OS before i take them out
11:43:36 <Nothing\> cuz i was used to just taking them out for years until windows started giving me a hard time about it
11:44:12 <Nothing\> and god help you if you're trying to figure out how to properly "eject" a flash drive on some obscure device like a TV
11:44:34 <Nothing\> takes you 15 minutes just to find the option
11:44:55 <jaymax> Something I found hilarious in high school, were the Novell NetWare login prompts on Win98. The [?] button was way more than a tooltip, and I showed my friends how they can browse the web withour ever logging in.
11:47:32 <+electrohead> Yes.
11:47:43 <+electrohead> Man, the good ol' days. I totally miss them
11:48:20 <jaymax> What ended up depressing me was when Win98 was still being used on most hospital PCs in 2005, when I did a work placement there. The failings of DOS-as-a-internet-connected-PC was hitting hard by that point.
11:48:47 <+electrohead> I remember being in typing class, and internet explorer was "not accessible", because they had no desktop icons whatsoever, and the shortcut wasn't located in the start menu. all I did was win key+R, "iexplore.exe", and *poof*
11:48:58 <+electrohead> Ouch
11:49:07 <jaymax> There was a leaderboard in the IT dept for how many spyware files removed in one trouble ticket.
11:49:17 <+electrohead> I can just imagine
11:49:39 <+electrohead> Heh, that same year, I edited the shut-down graphics, using mspaint, and got caught
11:49:49 <+electrohead> They discovered I did way more than that, and almost called the cops
11:50:06 <+electrohead> Was the only time I ever did something malicious, and learned from that very quickly
11:50:12 <jaymax> I think I won - I found a PC that was cloning two more DLLs every five minutes - noone noticed in the pathlab for weeks.
11:50:29 <+electrohead> Heh, what virus/malware was it?
11:50:59 <jaymax> I don't remember, was too long ago.
11:51:34 <+electrohead> Ahh ok
11:52:13 <+electrohead> I remember the ILoveYou virus, Melissa virus, and .. Michelangelo?
11:52:17 <jaymax> Just kept making randomly-named (but vaugely legit-looking) files. Like wdjvkey.dll
11:53:29 <jaymax> I remmeber the CodeRed mailbomb that cam out around the same time as Mountain Dew was promoting their Code Red drink. Unfortunate branding.

11:56:48 <jaymax> I found the source code for Win2000 and/or XP a year ago - my sister longs for the days of XP again so maybe I should see if I can compile it with the important patches, but into some obscure architecture (like SPARC).
11:57:13 <+electrohead> Nice, you'll need to share details once you do that, you know :p
11:58:22 <jaymax> Yeah, the vector of attack would me much reduced - ideally I would want to keep it somewhat obscure.
12:07:57 <jaymax> A family member got a fullscreen modal that locked her phone - some of it transcribed as:

16:38:46 <Zsjoelfir> I tried to sleep.
16:38:50 <Zsjoelfir> and drove to work
16:38:55 <Zsjoelfir> that was basically my last 8 hours
16:39:08 <+electrohead> fought with win98, fought with drivers, then I soldered in a second male RS232 connector into the serial adapter, since the original connector had fucking connector posts on it, and the line emulator had posts as well >.<
16:41:59 <+electrohead> I'm literally dancing over here, I can't believe this fucking thing still works 100%
16:42:11 <Zsjoelfir> nice^^
16:42:24 <+electrohead> and I just realized, so after connecting everything, it updated the unit, therefore, I need to perform ROM dumps again
16:42:34 <+electrohead> and update the post on the forums

17:15:29 <Zsjoelfir> its mostly my teammates here, so that is doable. annoying will be the thursday meeting all four weeks with mr. big boss. that is a bit annoying I guess.

18:19:26 <Zsjoelfir> I still like how one of my workmates answers the phone. His name is Boss and he has a very strong, loud voice. "THIS IS RAIDSONIC, BOSS, HELLO?????"
18:23:27 <K> Boss Boss
18:23:55 <K> it will be fun when he advances to be Mr Big Boss Boss
18:25:55 <Zsjoelfir> hehe
18:26:42 <Zsjoelfir> sadly he is only the same... "rank" as me, would be even funnier if he would realy be mr. big boss :P

19:47:53 <Halcyon> Fucking RCD is tripping again
19:48:46 <K> the fucker!
19:49:05 <K> did the elechicken come yet?
19:49:57 <Halcyon> Yeh came today. Breaker would reset fine in the morning, stayed on all day.
19:50:05 <Halcyon> He checked for earth leakage, nothing.
19:50:18 <Halcyon> Randomly, it flicks off
19:54:37 <K> huh
19:54:54 <Halcyon> Around the same time last night too
19:55:09 <Halcyon> The breaker trips and it won't reset, just keeps tripping off
19:55:14 <Halcyon> Wait until the morning, it comes good again
19:55:26 <K> a short somewhere ?
19:55:35 <Halcyon> But where?
19:55:45 <Halcyon> Even with all appliances unplugged, it trips
19:55:55 <K> $(how much is your house worth) dollar question
20:09:28 <Zsjoelfir> is it humid around you at this time of year? maybe some humidity creeping into some old fixture?
20:32:38 <Halcyon> No quite, the opposite, it's quite dry
20:32:42 <Halcyon> About 40% RH
20:32:50 <Halcyon> Also it's a new house (under 10 years old)
20:36:26 <Ampera> lol
20:36:30 <Ampera> whole house GFCIs
20:36:37 <Ampera> you foreigners are so cute
20:36:48 <Halcyon> It's not the whole house, just one circuit
20:36:56 <Ampera> interesting
20:36:58 <Halcyon> I have like 8 different circuits
20:37:00 <Ampera> we don't have that either
20:37:03 <Ampera> only 8?
20:37:10 <Ampera> we have maybe 20-30
20:37:32 <Halcyon> 2 power, 2 lights, 1 water pump, 1 AC, 1 comms/server, 1 oven
20:37:56 <Ampera> Afaik this house isn't wired for separate lighting and power circuits.
20:38:02 <K> everything is bigger in the usa!
20:38:05 <Ampera> the circuit layout basically makes no sense
20:38:12 <Ampera> which is not uncommon for US houses
20:38:40 <Ampera> so one circuit could be half the outlets and all the lights in the kitchen, and all of the bathroom
20:38:42 <Halcyon> The house is roughly split in half. The east power/lights have their own breaker as does the west.
20:38:51 <Ampera> another could be a few outlets in one room, then outlets on an entire other story
20:39:18 <K> more fun for the electricians
20:39:40 <Ampera> we also have two 30A dryer circuits, and either 1 or 2 50A stove circuits
20:39:43 <Ampera> both 240V
20:40:10 <Halcyon> The electrician said the chances of a faulty breaker is extremely low. Not unheard of but he has only seen a few in his time.
20:40:18 <Halcyon> And it's ABB branded too, not some cheap Chinese shit
20:40:40 * Ampera plays with Halcyon's Square D
20:41:34 <Halcyon> The only thing I can think of that has changes is the new rack, but all the equipment was pre-existing
20:42:10 <Ampera> probably water or moisture in a line somewhere with some busted insulation
20:42:19 <Ampera> do you have any mains power outside?
20:42:35 <Halcyon> Yes but on a difference circuit
20:42:41 <Halcyon> *different
20:43:02 <Ampera> what is this faulty circuit providing
20:43:28 <Ampera> I mean it could also just be something you plugged in that has developed a fault to ground you're unaware of
20:43:29 <Halcyon> Power outlets to the east side of the house, dishwasher, microwave, cooktop, range hood and gas hot water
20:44:10 <Ampera> plenty of stuff to where a moisture based fault to ground could not inconceivably exist
20:44:30 <Halcyon> True, but I've disconnected those appliances and nothing
20:44:38 <Ampera> if only you didn't have that GFCI, then you could figure out which of them has burst into flames
20:45:16 <Halcyon> That would be easier, yes.
20:45:21 <Halcyon> Or the one that gives you a zap
20:45:41 <Ampera> well then that wouldn't be a fault to ground, at least not right up until you touched it
20:46:00 <Halcyon> At least I'd have a particular event to tie it to
20:46:59 <Ampera> thinking about these circuits reminds me of the cable we have for the 50A outlet that's feeding my servers
20:47:06 <Ampera> damn thing is coarsely stranded aluminum
20:47:19 <Halcyon> *Aluminium
20:47:31 <Ampera> I knew you were going to say that. I specifically spelled it right just so you could be wrong.
20:47:52 <Halcyon> Everywhere else in the world spells it the usual way :P
20:47:54 <Ampera> was a right pain in the ass to install it into the outlet
20:48:14 <Ampera> there are plenty of languages that don't even have a latin alphabet that are literally incapable of spelling it the "usual" way
20:48:32 <Ampera> it's almost like we speak different dialects or something.
20:48:49 <Halcyon> Yes, we speak regular English. You guys speak whateves
20:49:20 <Halcyon> Maybe the extra syllable was too hard? :P
20:49:20 <Ampera> You don't even speak regular English, you guys have plenty of regular slang completely and totally foreign to "regular" English
20:49:31 <Halcyon> Slang is entirely different
20:49:38 <Halcyon> We're talking about a chemical element
20:49:42 <Ampera> *regular -> common
20:49:55 <Ampera> as in, elements of a language which exist in common speech, as opposed to academia
20:50:28 <Halcyon> Well you and Canada can go hang out together. We'll just be over here with the rest of the English speaking world.
20:50:28 <Ampera> I think you're just mad the world isn't exactly as it is in your image.
20:50:30 <Ampera> ya racist
20:50:34 <Ampera> >:D
20:50:37 <Halcyon> :P
20:50:46 <Halcyon> Fuck I hate Americans :P
20:50:52 <Halcyon> I wish you were more like the Indians
20:50:54 <Ampera> you're a racist, father!
20:51:01 <Ampera> I thought you hated the Asians.
20:51:11 <Halcyon> No, they are lovely. Food is great too.
20:51:23 <Ampera> You just think they're mentally incapable of driving.
20:51:31 <Halcyon> Some, yes.
20:51:37 <Ampera> I rest my case.
20:51:39 <Halcyon> But the same applies to some white women too :P
20:52:33 <Ampera> I mean if you want to make the case that any demographic will exhibit common human tendencies, you could do so without having to specifically single down a single race or gender.
20:52:55 <Ampera> but you know, do what makes you feel comfortable, wouldn't want you to have to deal with a diverse and fair world or anything.
20:52:57 <Halcyon> OK... let's talk about brown/caramel people then?
20:52:57 <Halcyon> :P
20:53:02 <Ampera> "caramel"
20:53:05 <Ampera> hahahaha
20:53:13 <Halcyon> Just being all-inclusive
20:53:18 <Halcyon> Wouldn't want to single anyone out
20:54:05 <Ampera> There's a difference between overt inclusivity for the sake of inclusivity, and the specific malicious singling out of a demographic to make a stereotypical generalization
20:54:21 <Halcyon> You know I don't really care right? I'm just shit-stirring
20:54:34 <Halcyon> All that matters is penis size. Nothing more.
20:54:35 <Halcyon> :P
20:54:40 <Ampera> Oh I know, but I enjoy planting just a few seeds to hopefully some day make you think you're a terrible person.
20:54:50 <Ampera> When in reality you're just as flawed and irritating as anyone else.
20:54:55 <Halcyon> Yep
20:55:14 <Halcyon> The difference is, no one cares over here.
20:55:22 <Ampera> Some day I'd love to rent a commercial/industrial building of some sort as like a workshop
20:55:26 <Halcyon> As the song goes... everyone's a little bit racist.
20:56:00 <Ampera> somewhere I can dick around with 3 phase power and run high power gadgetry without stressing the power bill so much
20:56:31 <Halcyon> You want an abandoned warehouse.... where you can dick around.... sounds about right
20:56:41 <Ampera> when did I say abandoned
20:56:50 <Ampera> or warehouse for that matter
20:56:52 <Halcyon> I was paraphrasing
20:57:10 <Ampera> we have these sort of buildings that are kinda a mix between commercial and industrial property
20:57:32 <Ampera> as in you might see a common business (or even a church) right next to a company that did metal fabrication or something else technical
20:59:19 <Halcyon> I hate you
20:59:24 <Halcyon> I'm going to go lay in bed
20:59:28 <Ampera> I love you
20:59:32 <Halcyon> :)
20:59:33 <Ampera> let me lay down right next to you
20:59:41 <Ampera> and we can start talking about that wang of yours
20:59:45 <Halcyon> Only if you keep your hairy ass to yourself
20:59:45 <Ampera> and what we could do with it
20:59:59 <K> cease the thing, right now!
21:00:04 <Halcyon> Sorry K
21:00:30 * Ampera nails a notarized and stamped Australian homosexuality permit to the wall
21:00:38 <Ampera> we have a loicense, no worriers mate
21:00:44 <Halcyon> Hahaha
21:01:22 <K> but do you have a registration for it>
21:01:23 <K> ?
21:01:23 <Halcyon> But seriously, I'm going to go lay in bed. I have the shits. This electricity thing is annoying me
21:02:04 <K> it is unsettling
21:02:39 <K> are the wires in distribution box long enough to swap the breakers?
21:02:58 <K> just to cross-test
21:03:06 <Halcyon> They are just going to replace the breaker tomorrow.
21:03:16 <Ampera> Don't tell him to dick around with high voltage, he might zap himself straight on accident.
21:03:39 <Ampera> Then I'd have to find some other flagrant homosexual misanthrope to torment.
21:03:57 <Halcyon> The chances of having two faulty breakers is astronomically low.
21:07:03 <Halcyon> Anyway I'm going to bed. Night all. Love you Ampera.
21:07:04 <Halcyon> xox
21:07:11 <Ampera> <3 <3 <3 <3
