00:01:40 <Ampera> time to go get around 8 litres of water and put it in my fridge
00:02:50 <Ysjoelfir> enjoy :)
00:02:53 <hsn> hope 8 liters of wasser come to ur head when u open the fridge Ampera :)
00:03:00 <Ysjoelfir> lol^^
00:07:08 <Ampera> hsn, that's sort of the point
00:07:15 <Ampera> I'm not sure how else you're supposed to drink water than via your head
00:07:23 <Ampera> or rather more specifically, your face
00:08:45 <hsn> all u have to do is to open ur mouth 8 liters wide before .. Ampera
00:09:02 <Ampera> eevblog convert 8 liters to inches
00:09:03 <EEVBlog> I can't seem to convert between those two units.
00:09:06 <Ampera> >:(
00:09:12 <Ampera> you weirdos and your funky units
00:09:27 <hsn> eevblog convert 10awg to mm
00:09:27 <EEVBlog> I can't seem to convert between those two units.
00:09:56 <K> eevblog convert 1 ampera to hsn
00:09:56 <EEVBlog> I can't seem to convert between those two units.
00:10:01 <K> useless.
00:10:45 <hsn> eevblog convert 1 hsn to tonns
00:10:45 <EEVBlog> I can't seem to convert between those two units.
00:10:57 <hsn> eevblog convert 1 tonns to kg
00:10:57 <EEVBlog> I can't seem to convert between those two units.
00:11:02 <hsn> eevblog convert 1 tons to kg
00:11:02 <EEVBlog> The result is: 907.185 kg
00:11:11 <K> u wot
00:11:25 <Ampera> hahahahaha
00:11:35 <Ampera> eevblog convert 1 metricton to kg
00:11:35 <EEVBlog> The result is: 0.001 kg
00:11:45 <Ampera> now /that/ is wrong
00:11:49 <Ampera> let me see why that is
00:11:54 <Ampera> probably got a conversion backwards
00:12:14 <hsn> what the heck is imperial tons
00:12:26 <Ampera> the same thing as a US ton
00:12:31 <Ampera> eevblog convert 1 ton to lbs
00:12:32 <EEVBlog> The result is: 2,000 lbs
00:12:44 <hsn> Ampera, no
00:12:58 <Ampera> yes
00:13:00 <hsn> google "tons to kg"
00:13:07 <Ampera> I'm aware, that's a mistake on my part
00:13:07 <K> this is offensive.
00:13:13 <hsn> and the tool will have "US TON" and "imperial ton"
00:13:15 <Ampera> all the conversion factors are manually entered, I was bound to make a mistake
00:13:16 <Ysjoelfir> I looked it up, he's right^^ though in ell but USA tons usually refers to metric tons
00:13:19 <hsn> which gives 2 different values
00:13:39 <Ampera> in the US, tons mean US tons
00:13:45 <Ampera> you must say metric tons to mean metric tons
00:13:46 <Ysjoelfir> so don't bash on Ampera :)
00:13:51 <Ysjoelfir> yep
00:14:02 <Ysjoelfir> well, at least in the US of A
00:14:06 <hsn> 1 ton imperial = 1016.05 kg
00:14:16 <hsn> 1 us ton = 907 kg
00:14:18 <hsn> ?!
00:14:18 <Ysjoelfir> but since EEVBlog is a product from the US of A thats fine to me
00:14:24 <Ampera> wait
00:14:27 <Ampera> there are US and imperial tons?
00:14:37 <hsn> idk i first time see this crap xD
00:14:39 <Ysjoelfir> wut? 3 tons? oO
00:14:52 <Ampera> huh
00:14:53 <Ampera> you're right
00:16:24 <hsn> The US defined a hundredweight (“cwt”) as 100 pounds, and thus a US ton is 2000 pounds. (907.1847 kg) (The very literal Americans.)
00:16:24 <hsn> When the UK later defined Imperial measures, they wanted 1 cwt to be an even multiple of 14-lb. stones, and so an Imperial hundredweight is 8 stone, 8x14=112 pounds; thus an Imperial ton is 112x20= 2240 pounds (1016.047 kg).
00:16:29 <hsn> https://www.quora.com/What-is-the-difference-between-a-metric-and-an-imperial-ton
00:17:16 <hsn> so never use ton ..
00:17:21 <hsn> kg is ur friend
00:17:27 <Ampera> fuck that
00:17:30 <Ampera> I'll use my own tons and pounds
00:17:44 <hsn> i dont even want to know what is ton now ..
00:19:38 <hsn> ok .. the problem is in me ..
00:19:59 <hsn> im not working from morning till now .. and now my boss in phone call im annoyed from him :D
00:20:09 <hsn> like i need to focus ..
00:21:10 <EEVBlog> New EEVBlog Tweet: For those playing along at home, these seems to be the best options. So what's your choice for an (approx AUD$2k) mobile occasional use 17" video editing machine (NOT for gaming):

00:23:11 <hsn> dave has a problem
00:23:25 <hsn> "playing along at home" "not for gaming" ... ?!?!
00:26:47 <Ysjoelfir> löl
00:26:51 <Ysjoelfir> that aussie slang
00:27:08 <ibiza> shazzaaaaaaa
00:27:43 <hsn> :)
00:28:03 <hsn> 1 fcking hour left to me
00:28:06 <hsn> faking that im working
00:28:15 <hsn> and then im free to home
00:28:15 <hsn> :D
00:28:58 <Ysjoelfir> lol
00:29:01 <Ysjoelfir> I AM working right now
00:29:12 <Ysjoelfir> being at home office I'm hardly working
00:29:13 <Ysjoelfir> erm
00:29:22 <Ysjoelfir> working hard I mean of course!
00:29:53 <hsn> ja ja :D
00:30:29 <hsn> workingly hard
00:31:34 <ibiza> did anyone else sign up for irpg ?
00:31:46 <ibiza> where are the stats link again for here
00:33:19 <hsn> not me
00:37:42 <Ampera> one conversion I will not implement right now is AWG
00:37:53 <Ampera> because I don't feel like a parser exception for 00 000 and 0000
00:38:05 <Ampera> and the formula is just batshit
00:38:56 <hsn> nooooooooo
00:39:04 <hsn> please implement it when >0
00:39:25 <hsn> no care for awg 00's
00:39:40 <hsn> mostly awg 16->30
00:40:49 <hsn> eevblog suggestionbox awg-convertion
00:41:09 <hsn> eevblog AmperaMailBox awg-conversion
00:41:36 <hsn> eevblog todo awg-conversion
00:41:37 <hsn> :(
00:43:23 <Ampera> alright alright
00:43:34 <Ampera> I stopped being lazy and threw in the parser exception
00:44:18 <Ysjoelfir> I would make it as a lookup table, as the formula is - as you said - shitty. noone could get a 2.63mm² wire :P
00:44:40 <Ysjoelfir> if that is somehow easyer, I dunno
00:44:56 <hsn> Ampera,
00:45:06 <hsn> i got a suggestion
00:45:11 <Ysjoelfir> Also Ampera, we highly appreciate your effort, making the bot even better :)
00:45:17 <hsn> eevblog help
00:45:26 <Ampera> it'll be diameter based
00:45:36 <Ampera> do the circular area conversion yourself :P
00:45:38 <hsn> this is infinite link : https://pastebin.com/6hHL6Rvu ?
00:45:56 <Ampera> wha?
00:46:05 <hsn> does it ever expire ?
00:46:15 <Ampera> it says right on the page that it doesn't
00:46:23 <hsn> can u edit it ?
00:46:59 <hsn> is it possible to load the lookup tables from pastebin links ? :)
00:47:13 <Ampera> there's no lookup table
00:47:18 <Ampera> I'm just implementing the formula
00:47:35 <Ampera> which means technically you could use fractional AWG
00:47:44 <Ampera> I've already implemented 00 000 and 0000
00:47:55 <hsn> then we can create pastebin .. and u plug the url only ? .. one master pastebin table for other lookup tables urls ..
00:47:59 <K> calm down there satan
00:48:21 <hsn> K :D
00:48:24 <Ampera> what's this about lookup tables
00:48:26 <Ampera> I'm not using lookup tables
00:48:28 <Ampera> why would I
00:48:43 <Ampera> the formula is annoying but not impossible
00:48:51 <hsn> because then we can convert Ysjoelfir time to hsn time
00:49:05 <hsn> :D
00:49:07 <Ysjoelfir> because the formula is shitty and you can't just get most of the diameters it produces ;)
00:49:45 <Ampera> it's defined as d=.005*92^((36*AWG)/39) right?
00:50:11 <Ysjoelfir> probably
00:50:46 <hsn> function OnCalc3()
00:50:46 <hsn> {
00:50:47 <hsn> var a = document.calcform.a.value;
00:50:47 <hsn> //d = 0.127*Math.pow(92,((36-n)/39));
00:50:47 <hsn> //a = Math.PI/4*d*d;
00:50:47 <hsn> var d = Math.sqrt(4*a/Math.PI);
00:50:51 <hsn> var n = -39*Math.log(d/0.127)/4.521788577+36;
00:50:53 <hsn> n = Math.round(n);
00:50:55 <hsn> if( n==-1 ) n="00";
00:50:57 <hsn> if( n==-2 ) n="000";
00:50:57 <Ampera> oh god
00:50:58 <Ampera> no no no
00:50:59 <hsn> if( n==-3 ) n="0000";
00:51:01 <hsn> document.calcform.x.value = n;
00:51:02 <Ampera> >:(

00:51:25 <Ampera> what is that, javascript?
00:51:38 Join: hsn ([email protected]) to #EEVblog
00:51:51 <hsn> oh man what did i do
00:51:56 <hsn> to deserve this
00:52:10 <Ampera> flood the channel
00:52:24 <Ampera> I don't even use javascript
00:52:25 <hsn> its small code
00:53:11 <Ampera> the inverse formula is even worse
00:53:44 <Ampera> awg = -39*log92(d/0.005) + 36
00:53:53 <Ampera> log base n for nice
00:54:08 <hsn> wait
00:54:26 <hsn> -39*Math.log(d/0.127)/4.521788577+36;
00:54:44 <Ampera> YES BUT I AM NOT USING JAVASCRIPT
00:54:47 <Ampera> /kick hsn
00:54:58 <hsn> its not javascript man
00:55:04 <hsn> math .
00:55:06 <Ampera> then it's something I've never even seen before
00:55:27 <Ampera> and can you stop backseat programming for me and let me figure this shit out on my own
00:55:34 <Ampera> I'm not an idiot
00:56:08 <hsn> dude im trying to know .. how log92(d/0.005) became log(d/0.127)
00:56:23 <hsn> not trying to teach u somthing .. as u know i cant anyway :)
00:57:03 <Ampera> probably because that's a derivative of the notion that lognX = logeX / logeN
00:57:44 <hsn> ah lol
00:57:48 <hsn> ya
00:59:38 <Ampera> I have -39 * (Math.log((value * 0.00000000393701) / 0.005) / Math.log(92)) + 36;
00:59:56 <Ampera> for the conversion from angstroms to AWG
01:00:20 <Ampera> with value * n being the conversion factor for the unit converted to inches
01:01:40 <hsn> eevblog convert (eevblog convert 20awg to mm)mm to inch
01:01:40 <EEVBlog> I can't seem to convert between those two units.

01:03:00 <EEVBlog> I can't seem to convert between those two units.
01:03:35 <hsn> K, its under unit testing :D
01:05:34 <Ampera> hsn, as a professional QAck I approve of that joke

05:15:51 Mode: (by ChanOP) +o ThunderSqueak
05:15:53 <electrohead> and I know, a small delay, lol
05:16:05 <electrohead> I dropped my car off today at the shop
05:16:11 <Ampera> electrohead, fine, just creating test data, the most funnest thing in the whole world
05:16:32 <electrohead> how much data do you have to create?
05:16:50 <Ampera> not much
05:16:57 <Ampera> maybe 50 entities or so
05:18:31 <electrohead> ahh, not too bad then
05:18:34 <DHess_US> Fucking Windows 10. The "COM Surrogate" which is suppose to prevent other programs from crashing, crashed.
05:18:58 <Ampera> ah the days of having to deal with Windows 10's processes just eating half the CPU because they fucking want to
05:19:25 <electrohead> I attempted to virtualize win10 recently
05:19:30 <electrohead> will never try that again
05:19:33 <Ampera> I'm doing it right now for work
05:19:37 <Ampera> works fine on QEMU
05:19:45 <DHess_US> I'll be able to do that on my new system.
05:19:57 <DHess_US> It will have enough RAM.
05:20:18 <electrohead> my main server has enough RAM and CPU cores/threads, but that's a linux-only machine
05:20:29 <electrohead> should probably build a new, updated machine, though
05:20:37 <Ampera> I thought about doing full system Xen, but decided it wouldn't give me really much that I actually wanted
05:20:49 <Ampera> what do you mean by linux-only
05:20:58 <Ampera> as in you just don't want to put non-linux VMs on it?
05:20:59 <DHess_US> My new workstation is a 3700X with 64G
05:21:05 <electrohead> exactly, lol
05:21:14 <Ampera> DHess_US, similar, I have a 3950X with 64G
05:21:45 <Ampera> and I could do all of this on my laptop from work, but I'd have to switch over to PBP mode on my monitor and it's just slightly more annoying than it needs to be
05:21:52 <Ampera> SPICE has shit latency, but it's at least convenient
05:22:23 <DHess_US> I'm kind of disappointed in the CPU cooling. The processor is 65 watts instead of the 120 watts of my Phenom II 940, but with a bigger heat sink it runs hotter.
05:22:32 <DHess_US> It makes sense, but it is still annoying.
05:22:46 <Ampera> Boosting is a bit more of a thing than it was on the old Phenoms I imagine
05:22:55 <DHess_US> Running a power virus results in junction temperatures up to 65C.
05:23:09 <DHess_US> My old system is more like 55C with a not quite as good heat sink.
05:24:01 <DHess_US> I don't have the case side panels on yet. The CPU heat sink has 3 fans and the case has 4 filtered intake fans.
05:24:01 <Ampera> I eliminated that concern by stuffing an overkill 240mm AIO water cooling system into the machine
05:24:23 <DHess_US> Yea, water cooling is the only way to improve it at this point.
05:24:31 <DHess_US> Old system has a Hyper 212
05:25:01 <Ampera> the heatsink has 3 fans and you're getting 65C temps on a 65W Zen 2 CPU?
05:25:06 <Ampera> what
05:25:26 <DHess_US> New system has https://pcper.com/2019/11/%E2%80%8Bscythe-fuma-2-scfm-2000-review/
05:25:28 <Ampera> what's the TIM?
05:25:39 <DHess_US> TIM is the paste which came with it.
05:25:55 <Ampera> maybe it's just shit TIM
05:26:01 <DHess_US> Seems unlikely
05:26:01 <Ampera> because you shouldn't be getting temps that shit with it
05:26:16 <Ampera> you'd be surprised
05:26:21 <Ampera> there are some /shit/ compounds out there
05:29:27 <Ampera> Only thing I'm wondering is if it's just boosting that hard, as afaik that 65W is likely an average with the stock cooler
05:29:36 <Ampera> but a number that can go considerably up, and thus produce more heat
05:30:48 <DHess_US> It actually says 80W
05:31:07 <Ampera> the current power consumption or the CPU TDP
05:31:13 <DHess_US> CPU PPT 88W at the moment.
05:31:40 <Ampera> and you're getting 65C right now, or do you only get that when you stress it
05:31:43 <DHess_US> Core + SoC is 61W
05:31:48 <DHess_US> 61C right now
05:31:51 <DHess_US> It varies a little.
05:31:58 <Ampera> SoC?
05:32:16 <DHess_US> SoC is everything not the CPU cores
05:32:16 <EEVBlog> 42, DHess_US!
05:32:23 <Ampera> so package temp
05:32:56 <DHess_US> 62C junction temp, 35W core, 24W SoC
05:33:20 <DHess_US> And the program running is doesn't quite drive maximum power, but it is close.
05:33:22 <Ampera> why are you calling it SoC
05:33:38 <Ampera> so this isn't idle, it's stressed?
05:33:41 <DHess_US> I have it set to exercise memory.
05:33:53 <DHess_US> Yes, this is stressed more than any typical application.
05:34:07 <Ampera> well then that's actually a fairly reasonable max load temperature
05:34:20 <DHess_US> All cores running at 4.2GHZ because it is memory limited
05:34:34 <Ampera> especially for a good air cooler @ 88W
05:34:44 <DHess_US> The point is that my old processor running the same benchmark with more power has a lower temperature with a worse heat sink.
05:35:01 <Ampera> seems like that would break the laws of thermodynamics.
05:35:08 <DHess_US> I know why what should be, but it is still annoying.
05:35:21 <Ampera> Why is it so?
05:35:25 <Ampera> as that power has to go somewhere...
05:35:42 <DHess_US> No, the Zen2 has a physically smaller die size than the Phenom 2, so it has a higher junction to case thermal resistance.
05:36:17 <DHess_US> So it is lower power, but it has even less area to conduct the heat out.
05:36:30 <Ampera> ah
05:36:46 <Ampera> still, 65C isn't bad
05:37:16 <Ampera> do you know how many core dies you have on that MCM?
05:37:27 <Ampera> I don't know off the top of my head
05:37:44 <Ampera> as in, not the I/O controller, the actual processing dies
05:37:50 <Ampera> either 1 or 2
05:38:16 <DHess_US> Might still replace thermal paste. I have some options, https://ibb.co/6F2wKBP
05:38:26 <DHess_US> 2 core dies
05:38:52 <Ampera> as presumably the CPUs with only 1 core die would thus have even less thermal contact for the energy they consume
05:39:36 <Ampera> I know fuck all about thermal paste, but are you sure that stuff is good for the amount of heat and surface area involved?
05:40:24 <Halcyon> Morning all
05:40:26 <Halcyon> Stupid work :(
05:40:31 * Ampera hugs Halcyon
05:40:39 <Ampera> WORK DAMN YOU
05:40:44 <Ampera> STOP BREAKING
05:40:49 * Ampera snaps Halcyon in half
05:40:52 <Halcyon> :P
05:41:28 <DHess_US> Not exactly, but having three separate dies, there is an I/O die, does spread the heat out a little on the heat spreader.
05:42:03 <Ampera> yeah but I imagine the amount of heat those can transfer will potentially go down as you begin transferring more and more heat at higher temperatures
05:42:05 <Ampera> unless I'm full of shit
05:42:17 <DHess_US> Oh, the ones I linked are fine, but I just used the tube of what came with the heat sink to get rid of it.
05:42:19 <Ampera> but most CPU thermal pastes are, as I understand it, optimized for the purpose.
05:42:35 <DHess_US> No, thermal compound doesn't work liek that.
05:42:51 <Ampera> as I said, I know nothing about thermals pastes
05:43:00 <Ampera> just seems like something they might do
05:43:40 <Halcyon> I just use the bog standard Dow Corning stuff
05:43:43 <Halcyon> Works just fine
05:44:07 <Ampera> I use arctic silver because my dad's done the same and it works fine for me
05:44:18 <Halcyon> Yeh that's fine too, albeit expensive
05:44:52 <Ampera> It's not too bad
05:45:40 <DHess_US> On paper the Wakefield 120 and MG Silicon thermal compound are about the same, and the Super stuff is about 3 times better.
05:46:26 <DHess_US> Wakefield 120 is what most people think of as the decades old "white" thermal compound.
05:47:18 <DHess_US> It is the standard. The "super thermal compound" shown there has aluminum oxide (sapphire) in it.
05:47:26 <Halcyon> I miss the old Beryllium oxide stuff. My dad had a small container when I was a kid. It probably lasted me until about 10 years ago.
05:47:37 <Halcyon> Just don't get it in your mouth
05:48:43 <Ampera> Halcyon, but I wanna get your stuff in my mouth
05:48:44 <Ampera> :/
05:49:25 <Halcyon> :P

05:52:35 <Ampera> loser
05:52:37 <Ampera> do it on zero
05:52:40 <Ampera> fucking pansy
05:56:07 <DHess_US> Huh, maximum power virus which runs out of the L3 cache is only 59C and runs the clock speed at 3.6GHz.
05:56:27 <DHess_US> I guess the large memory power virus results in more heating because the clock speed is higher and the I/O die is hotter.
05:56:52 <Ampera> oh great
05:56:54 <Ampera> cloudflare is fucking up
05:57:12 <DHess_US> The difference is that using all of the memory means the core spends more time halted waiting for results from memory.
05:57:24 <DHess_US> So the core produces less heat and the clock speed can be higher.
05:57:48 <Ampera> cloudflare status confirms it, they done fucked up
05:57:56 <Ampera> nice, the one time I go to update certs :P
05:59:24 <DHess_US> Kind of weird running an application which uses all 64G of memory.
05:59:36 <Ampera> how so
05:59:53 <Ampera> I run chromium just like the next guy
06:00:14 <DHess_US> hehe
06:02:03 <DHess_US> https://i.ibb.co/TK8vjbk/Untitled-1.png
06:03:12 <coppice> DHess_US: I guess you don't run big modelling jobs
06:06:36 <DHess_US> coppice, how is that?
06:06:43 <DHess_US> Because I have *only* 64G?
06:07:24 <DHess_US> Motherboard only supports 128G and unbuffered 32G ECC DDR4 isn't available yet.
06:08:01 <DHess_US> So would need a competely different motherboard and processor to support more memory.
06:08:16 <DHess_US> I'll settle for 64G.
06:26:48 <MrMobodies> Hello, I have been compromised:
06:27:03 <Ampera> we all make compromises
06:27:18 <MrMobodies> https://imgur.com/a/u6yIh0M
06:27:22 <MrMobodies> Rootkit
06:27:48 <MrMobodies> It gets through when the windows update is switched on
06:28:11 <MrMobodies> I am thinking DNS maybe compromised
06:28:18 <MrMobodies> using 8.8.8.8
06:28:19 <Ampera> wha
06:28:24 <Ampera> wha
06:28:36 <Ampera> what do you mean it gets through when windows update is switched on
06:28:37 <MrMobodies> I am devastated. Two weeks I didn't notice it
06:28:41 <MrMobodies> yes
06:28:42 Quit: PsySc0rpi0n ([email protected]) Ping timeout: 121 seconds
06:28:50 <Ampera> that's not an answer
06:29:17 <Ampera> a rootkit spreading through windows update is highly improbale
06:29:21 <Ampera> er, improbable
06:29:30 <Ampera> so is one of the world's largest DNS servers being compromised
06:29:36 <MrMobodies> I have came across many things, this is the first
06:29:44 <Ampera> you probably just did something dumb and got a virus
06:29:45 <MrMobodies> I hope it isn't but
06:29:52 <Ampera> wipe, restore from backup, enjoy
06:29:52 <MrMobodies> yes something happened somewhere
06:29:59 <MrMobodies> I did using disc images months ago
06:30:12 <MrMobodies> and i checked on them to find them past the 17th october
06:30:16 <MrMobodies> what is strange
06:30:23 <MrMobodies> all the of the machines had different passwords
06:30:31 <MrMobodies> that one that got it the first is my dad's
06:30:35 <Ampera> wait, this is something affecting multiple machines?
06:30:36 <MrMobodies> completely different password
06:30:38 <MrMobodies> yes
06:30:43 <Ampera> oh dear
06:30:45 <Ampera> nice worm
06:30:48 <MrMobodies> it didn't affect the ones with the yupdate switched off
06:30:56 <MrMobodies> and the module installer
06:31:00 <Ampera> it also just dawned on me you're using Windows 7
06:31:11 <Ampera> which very likely does have a big hole in Windows Update microsoft's not gonna be patching any time soon
06:31:25 <MrMobodies> nope, for now I got to do something,
06:31:52 <MrMobodies> set vlans on the switch and set them in a way no machine can communicate and look at migrating
06:32:08 <MrMobodies> that is something else I suspect
06:32:16 <Ampera> are you running windows 7 on all your machines?
06:32:32 <MrMobodies> you know what I am going to say, i can't stand it
06:32:43 <MrMobodies> I do have Windows 10 enterprise too on one of mine
06:32:44 <Ampera> I don't actually, but I'll take that as a yes
06:32:56 <MrMobodies> oh mostly yes sorry I misread
06:32:58 <Ampera> point being, play stupid games, win stupid prizes
06:33:27 <Ampera> you want advice or are just coming here to vent
06:33:37 <MrMobodies> talki and listen
06:33:47 <Ampera> does that constitute advice
06:33:53 <MrMobodies> oh
06:34:10 <Ampera> let me rephrase this, are you here asking for help
06:34:20 <MrMobodies> opinions
06:34:31 <Ampera> don't use Windows 7 on a network connected to the internet
06:34:45 <MrMobodies> yes, quite risky as I can see.
06:34:50 <Ampera> every machine in the house wiped, if you have cold backups use them
06:35:06 <Ampera> otherwise backup all your data you still have access to and isolate it in cold storage for now
06:35:06 <MrMobodies> got to get that sorted, backups already done
06:35:20 <Ampera> wipe all machines, not just Windows 7 machines, everything
06:35:31 <Ampera> if you're running a PC as a router wipe that too
06:35:44 <MrMobodies> Got a disc image on that too
06:35:52 <Ampera> is it stored on an unaffected machine?
06:35:58 <MrMobodies> yes
06:36:12 <MrMobodies> the laptop with the module updater switched off
06:36:22 <Ampera> good, when you get it all going again, update every single machine to Windows 10
06:36:32 <Ampera> I believe if you look hard enough you can still upgrade Windows 7 licenses to 10
06:36:40 <Ampera> (for free)
06:36:52 <MrMobodies> yes, with the ssd's that's shouldn;t be a problem
06:37:09 <coppice> does the trick of using the page for the disabled still work?
06:37:11 <Ampera> treat it like an actual virus, be wary of what contacted what even for a moment
06:37:16 <Ampera> coppice, that's what I was thinking of
06:37:24 <Ampera> as far as I know it or something like it still does
06:37:58 <MrMobodies> at the moment I don't trust anything there. I am certain it maybe hidden somewhere and may return.
06:38:07 <Ampera> See if that allows you to update using flash media, and keep everything off the network until everything is clean
06:38:12 Join: Polesch ([email protected]) to #EEVblog
06:38:16 <Ampera> good mentality
06:38:27 <Ampera> just clean it up, and make sure your firewall is operational
06:38:44 <Ampera> as even if it's through windows update, it sounds odd that it'd just come in it through your firewall
06:38:47 <MrMobodies> yep and I am going to isolate the network ports so they can't communicate
06:39:01 <MrMobodies> it makes me wonder if that has been compromised too
06:39:27 <MrMobodies> but I have a copy from the beginning of this year
06:40:27 <MrMobodies> I mean the firewall
06:40:38 <MrMobodies> but sorry if I sound like I was venting...
06:40:58 <Ampera> mistakes happen, learn what you did wrong, don't let it happen again
06:42:56 <coppice> and don't forget to self flagellate for your sins
06:48:47 <MrMobodies> I already feel humiliated.
06:48:54 <MrMobodies> and stupid
06:49:26 <MrMobodies> I should have done better to prevent this sort of thing.
06:52:02 <Ampera> Think of it this way, at least you don't feel good about it.
06:52:17 <Ampera> The benefit this brings is you now knowing better what not to do

09:30:41 <rust_collector> I have updated from 7 to 10, just reinstalling as usual, and entering the w7 key, and it just worked. ok, it could be a month or so ago...
09:30:56 * steve30 paws at T3sl4
09:31:16 <T3sl4> hi steve30
09:32:36 <rust_collector> Ysjoelfir, are you awake?
09:35:52 <steve30> I think I'll get a coffee
09:37:04 <Ysjoelfir> kind of
09:37:17 <rust_collector> oh well
09:38:34 <rust_collector> so, I am just thinking about figuring out how this china special power supply works. but... in what end would you start? it is a fairly simple thing, with a single sided board
09:41:46 * steve30 sits on T3sl4's lap
09:42:11 <T3sl4> does the steve30 want something?
09:42:11 <Ysjoelfir> I would see if there is already a schematic somewhere. if not I would just draw the schematic. since its single sided it should be pretty easy
09:42:29 * T3sl4 sniffs steve30's coffee
09:42:59 <steve30> I just wanted somewhere to sit while I sip my coffee :p
09:43:17 <rust_collector> right, but would you... say start drawing the opamp (which is the main part here) and go from there, or go from the input, or...
09:43:24 <T3sl4> rust_collector: not far from the application diagram
09:43:26 Quit: Dude ([email protected]) Ping timeout: 121 seconds
09:43:55 <Ysjoelfir> yep, would go from the main components usually :)
09:44:08 <Ysjoelfir> draw that more or less central on a sheet of paper and expand from there
09:44:12 <T3sl4> the real challenge is identifying the controller, maybe it's a 8-pin SMT you can read, or one of those 3 or 7 lead regulators, maybe it's a tiny 6-pin SMT you have to get lucky looking up
09:44:21 <rust_collector> T3sl4, eh? and yes, I guess that makes sense

09:45:02 <T3sl4> oh, is it not a power adaptor?
09:45:37 <rust_collector> it is a... uhm, phone repair power supply, so a crappy bench supply
09:46:17 <T3sl4> one of those with the stupid oval power button?
09:46:55 <rust_collector> adjustable voltage from 0 to 15v, and the current is limited to 1A. I just wonder if I can change it to have adjustable current limiting also...and... stuff.
09:47:08 <rust_collector> No, no oval buttons here. let me see
09:47:51 Quit: clarkos ([email protected]) Ping timeout: 121 seconds
09:47:59 <T3sl4> ah, my guess would be a Vbe shunt current limit, which you can make adjustable by adding a series resistor to the sense transistor's base and bleeding in some current
09:48:08 <T3sl4> it's still pretty crude, because Vbe varies with temp
09:48:38 <rust_collector> hmm, that sounds reasonable
09:48:47 <T3sl4> also the current needs to be from a current source, since a resistor from the (unreg) supply would bleed in more current as Vout drops, which gives a negative resistance (foldback) characteristic
09:49:42 <rust_collector> ah yes. that makes sense
09:49:53 <T3sl4> for sake of argument, https://media.cheggcdn.com/media%2F344%2F34446a74-f1fe-40a2-bdeb-eb9ca4400f48%2FphpBAcxB3.png that'd be a series resistor between the 1.2 ohm, and Q3 base
09:50:17 <T3sl4> then a current source (two diodes and a transistor, or the "ring of two", or a mirror, or etc.) outputting to the base
09:51:12 <T3sl4> ewww, that schematic has the opamp /direct driving/ a base, no current limiting, no emitter degeneration
09:51:22 <T3sl4> please ignore the rest of that lul
09:51:56 <rust_collector> well, I think I will try to draw this thing as it is first, and go from there

09:52:31 <T3sl4> i guess with 6 transistors it's a little more complicated, but i would expect to see something roughly like that
09:53:13 * Ysjoelfir has nothing to add to that^^
09:54:07 * T3sl4 adds a beer to Ysjoelfir
09:54:24 <rust_collector> it is a pretty crap device, but also pretty handy. I mostly bought it because it has a neat looking box, with 2 analog meters
09:54:42 <rust_collector> the transformer is too small, the rest is too small...
09:55:48 <T3sl4> the china specials tend to be... as you expect. the oval-button kind often boast 30V 5A and have relay tap changing, but the /three parallel transistors/ on the /200 cm^2 heatsink/ are more than happy to fail at a fraction of that rating
09:56:33 <T3sl4> also the fans in those things are as you expect, they'll put them on thermal switches and the bearings will be too shite for them to start
09:56:47 <rust_collector> heh, perfect

10:03:16 <T3sl4> at 15V 1A there's probably little that can go quite /that/ wrong, but i know they'll find a way
10:03:16 <rust_collector> I hope they at least used hot glue to put the switches on?
10:03:16 <T3sl4> i think those usually have a screwed-in push-on-push-off power switch
10:03:16 <rust_collector> sure. I think it would be fairly reliable, if you did not need any kind of precise voltage, because the transformer will probably burn before the rest will get damaged
10:03:16 <rust_collector> it is tiiiny
10:03:16 <T3sl4> my other experience with those sorts of wares, a 100V 10A switching supply, with almost as much common mode noise at the output, used 600V 50A IGBTs to do the power output, which is so overkill that it cooked off quite effectively when operating at low voltages and rated current
10:03:16 <T3sl4> heh, in fact the filter in this network https://www.seventransistorlabs.com/Images/LISN1.jpg i originally wound those CM chokes for one, just to get its noise down enough to be useful, put one on the mains side and one on the output
10:03:16 <Ysjoelfir> lol^^ nice :P
10:03:16 <T3sl4> the reason it couldn't do low voltages is the gate drive had transformers into 2SC1815s into the stupid IGBTs, so basically no gate current. it took a whole microsecond to switch on and off. at low voltages it's basically class A operation
10:03:16 <Ysjoelfir> I think I should go to bed though. I hope you are done with the schematic tomorrow morning rusty ;) I'm curious how that thing works
10:03:16 <T3sl4> if they had at least used judiciously rated parts like 5 or 10A IGBTs or FETs, it would've been fine
10:03:16 <rust_collector> that sounds like the one I used to adjust voltage to a fan. it works, but it gets very very hot, and it needs 9v or so, before it starts doing anything
