00:44:06 <Lemon> so I just got the systron donner and the wattmeter !
00:44:11 <Lemon> theres something weird with the dmm
00:44:35 <Lemon> when I measure something, the measure stays, and slowly go down when I remove the thing I was measuring
00:44:38 <Lemon> a few mv per mv
00:44:48 <Lemon> like a capacitor was discharging
00:45:05 <Lemon> and if I short leads, it goes down to somewhat zero, but when Iremove the short it slowly goes up
00:52:55 <steve30> That will be the input capacitance discharging. The input resistance will be very high, so it will take a long time to discharge.
00:53:32 <Lemon> yeah true its a 1Gohm input resistance
00:53:37 <Lemon> but why when nothing is connected it rises ?
00:53:50 <Lemon> thats normal too ?
00:54:30 <steve30> probably picking up noise
00:54:36 <steve30> sounds normal
00:54:58 <Lemon> it seems to go up by like 10mv per sec
00:55:09 <Lemon> ive seen capacitors building up charges
01:03:16 <Lemon> http://forum.wda-fr.org/download/file.php?id=1009&mode=view
01:03:23 <Lemon> I just got this wattampvolt meter too
01:03:36 <Lemon> but I have no idea where to plug probes, to test the voltmeter function
01:06:12 <Lemon> if someone have an idea :> i'd appreciate it !
01:41:09 <Lemon> Ysjoelfir you there bro ?
01:42:14 <coppice_> Lemon: they seem to have labelled the terminals for maximum confusion
01:42:23 <Lemon> yes totally
01:42:34 <Lemon> and I dont want to break anything
01:43:32 <Lemon> I just want to try measuring a battery, to see if it works
01:43:54 <Lemon> and this device is non existent on the net
01:44:01 <Lemon> theres just another peep who got it, but no infos
01:47:50 <Lemon> I don't even know if I risk anything plugging probes wront
01:49:49 <Ysjoelfir> I heard my name? Yes I'm kind of here, just playing^^ so reading is no prob on the second screen, but responding is somehow troublesome^^
01:50:02 <Lemon> ha I see :> I need your help !
01:50:07 <Lemon> I received the wattmeter
01:50:14 <Lemon> but I have no idea on where to plug probes, to read volts :>
01:50:19 <Lemon> it can read volts, amps and watts
01:50:28 <coppice_> well, the 2 terminals on the left seem to be for the 15V to 600V voltage range. The next 2 seem to be for the 6mA to 15A current ranges, and the following terminal is for the 30A current range. The 0V terminals for voltage and current must not be more than 10V apart. The confusing part is what the last 2 terminals on the right are for
01:50:30 <Lemon> and its labelled like 'fuck this they'll find out'
01:51:18 <Lemon> thats kind of what I was thinking yes !
01:51:28 <Lemon> it somewhat makes sense
01:51:33 <Lemon> but where is the common ?
01:51:41 <Lemon> lets say I want to measure a 9v battery
01:52:21 <coppice_> There doesn't seem to be a common. It appears to say the 0V for the voltage sensing and the 0V for the current sensing can be up to 10V different
01:53:10 <Ysjoelfir> I aggree with coppice_
01:53:24 <Ysjoelfir> it would be rather hard if there would be a "real" common
01:53:33 <Lemon> hmmrmmrmr
01:53:37 <coppice_> The right hand terminals are labelled 3-20ohm and 6-100ohm. The lower right hand switch has a position that says A 3-6V. Are those things connected?
01:53:40 <Lemon> too hard for me !
01:54:12 <Lemon> it goes from 6 ma to 15 amps it seems
01:54:19 <Lemon> theres another switch for volts
01:54:30 <Lemon> another to chose between volts, amps, watts and 'm'
01:54:39 <Lemon> one for + and -
01:55:59 <Lemon> so the big question
01:56:04 <Lemon> do I risk anything ?
01:56:12 <Lemon> its one strange device, theres absolutely no apparent way to take it appart
01:57:36 <Lemon> also the screw to set it to 0 seems to work when it wants
02:02:47 <Lemon> if I tilt it vertically it seems to works
02:02:53 <Lemon> but when it laying flat, nothing
02:03:06 <Lemon> thats one strange motherfock
02:17:07 <Ysjoelfir> Measuring Power isn't easy at all^^
02:17:15 <Lemon> ho but I just want to measure volts !
02:17:25 <Lemon> to see if the movement works first :>
02:17:31 <Lemon> where would you plug them probes ?
02:17:36 <Lemon> send help ! :>
02:18:00 <Ysjoelfir> I mean, just think about it - I work for a manufacturer that produces power analyzers. we have around 60 people working here, all getting paid just by the sales of power analyzers^^
02:18:17 <Ysjoelfir> u have a pic of the fron? let me look
02:18:26 <Lemon> the front ?
02:18:35 <Lemon> on sides and back theres nothing
02:18:53 <Lemon> http://forum.wda-fr.org/download/file.php?id=1009&mode=view
02:21:41 <Ysjoelfir> connect the voltage source to V anv Vo, switch the bottom right switch to V, the top right ti a suitable range.
02:22:07 <Lemon> the V on the left ?
02:22:11 <Ysjoelfir> that should be all that needs to be done to make that thing display
02:22:26 <Lemon> lets make it easier for the dumbass I am
02:22:31 <Ysjoelfir> I would assume that. otoh... hm
02:22:34 <Lemon> the black probe goes to which number ? :>
02:22:39 <Ysjoelfir> 2
02:22:41 <Ysjoelfir> red to 1
02:22:47 <Lemon> okkkk lemme try thanks bud
02:23:32 <rust_collector> but I want to see the other device
02:23:46 <Lemon> nothing
02:24:03 <Ysjoelfir> and what happenes when you connect it to black 3, red... 7?
02:24:07 <Lemon> im on V and 15 volts
02:24:35 <Lemon> nothing either
02:25:23 <Lemon> please dont tell me the movement died during transport again
02:25:28 <Lemon> the dude tested it, and it was working
02:26:36 <Ysjoelfir> well, then ask him how he tested it :) that should clear things up
02:26:47 <Lemon> when they say 15 to 00
02:26:49 <Lemon> 600
02:26:53 <Lemon> is it 15 volts minimum ?
02:27:13 <Lemon> lemme try to measure 15 volts with my supply
02:27:18 <Ysjoelfir> jep
02:29:13 <Lemon> okk so I injected like 20 volts
02:29:19 <Lemon> and suddently it jumped like shit
02:29:32 <Lemon> now supply at zero
02:29:37 <rust_collector> you need to look at your diet
02:29:41 <Lemon> the needle is on like 13
02:30:50 <Lemon> tried again, it jumped when I reached 20-25v
02:31:00 <Lemon> its stuck on 73-74
02:31:14 <Lemon> if I short leads it doesnt move either
02:31:36 <Lemon> so I touched it (on the black enclosure, a little tap) and it went back to zero
02:34:53 <Lemon> hmmm so if I tap it a bit it seems to work somewhat
02:35:05 <Lemon> well seems the movement works, at least
02:37:52 <Lemon> ha I seem to get something decent now
02:38:42 <rust_collector> did you do anything different, or did you just try one thing until it worked?
02:39:07 <Lemon> I kept tapping on it why fluctuating the voltage output from my supply
02:39:12 <Lemon> I tried different ranges too
02:40:48 <Lemon> it seems to be ultra sensible
02:42:12 <rust_collector> sensitive? well, it has to be, I guess
02:42:57 <rust_collector> but what about the other device??? i need pics
02:43:40 <Lemon> yes give me 5 minutes I'll take some buddy
02:43:49 <Lemon> by sensistive I mean I need to tap on it to work sometimes
02:53:13 <Lemon> https://imgur.com/a/elQPDiU rust_collector
02:53:17 <Lemon> heres the systron donner
02:54:02 <Lemon> thats funny because when I measure nothing, even with probes unplugged
02:54:10 <Lemon> the voltage rises by a few mv per seconds
02:54:17 <Lemon> like a capacitor would build a charge
02:54:38 <Lemon> and because it got a very high input impedance, if I measure something, the value stays and slowly drops mv by mv
02:55:01 <steve30> mmm, nice display :)
02:55:07 <Lemon> yes really nice !
03:01:18 <coppice_> whatever happened to systron donner?
03:01:47 <Lemon> it seems to be the property of emcore now
03:03:03 <coppice_> I don't think they make any instruments under that brand name any more
03:03:16 <Lemon> yeah
03:03:25 <Lemon> I never heard of this compagny before to be honest
03:03:31 <Lemon> it seems this dmm is from 1975
03:04:03 <coppice_> their instruments were common in the 70s
03:04:44 <coppice_> DMMs, frequency counters, power supplies and other small bench instruments like that
03:04:46 <Lemon> I wonder if its still precise, it indicateds 9.204v on a battery, while my keithley 175 indicates 9,18 something
03:05:05 <Lemon> but it got a 1Gohm input impedance, while the keithley got like 11Mohm
03:05:12 <Lemon> so maybe it plays a role
03:19:39 <rust_collector> aaah, that was good
03:20:04 <Lemon> well idk for the wattmeter, either the movement got some shit in it and it sticks (but I dont think so) or theres some static buildup problems, or something I dont know
03:21:06 <rust_collector> Maybe they run all the packages thru a large microwave oven, when you go for the cheap shipping
03:21:21 <Lemon> heh who knows
03:21:39 <Lemon> what amazes me is that theres no apparent way to take it appart
03:21:43 <Lemon> no screws, no clips etc
03:21:55 <Lemon> theres a missing feet, I thought it would be with them but nop
03:22:48 <rust_collector> if you find a manual for it, maybe it has some info on smashing the casing with big hammer, and putting the guts into the replacement case, tune it up, and glue the damn thing shut
03:23:06 <Lemon> pffrtt well maybe
03:23:10 <Lemon> its non existent on the net
03:23:11 <rust_collector> an older version of tamper proofing
03:23:17 <Lemon> theres only a picture of some random guy who got it
03:24:39 <rust_collector> it is pretty annoying, when you have an issue with something, and all you can find is a 12 year old thread on obscure forum, and the last post just says "yes! I fixed it" and that is it
03:25:52 <Lemon> yeah im used to that
03:27:06 <rust_collector> what is the idea of the new "auto" multimeters? the ones who tries to figure out what you are trying to do
03:27:17 <coppice_> there are repair instructions for a number of products which call from breaking something during disassembly, and always using a new part during reassembly
03:28:53 <Lemon> I like autorange but thats it, I can push buttons myself
03:29:27 <rust_collector> autorange is fine
03:30:42 <rust_collector> I sort of like the idea of buttons, and not the twist knob.
03:32:35 <Lemon> do you know if input impedance change the reading ?
03:32:46 <Lemon> between the systron with its 1Gohm and the keithley with 11Mohm
03:33:02 <Lemon> I see a difference of like 20mv from a 9v batt
03:33:28 <rust_collector> I doubt it would make a difference on a 9v battery, but, I do not know anything
03:33:56 <Lemon> yeah I wonder if one of my meters are out
03:33:58 <Lemon> 20mv is a lot
03:34:24 <rust_collector> it is pretty relative. in my world, 20mv is nothing, lol
03:35:43 <coppice_> the difference between your meter readings is 0.26%. What accuracy is specified for those meters?
03:41:05 <Lemon> like 0.002% + 0.003% reading after 1 year for the systron, and 0.03% + 2 counts for the keithley
03:42:25 <rust_collector> well, the keithley is out of spec. At least that is what I think
03:44:50 <Lemon> hmmm the ths710a measures 9.18 but its only a 3,5 digits, and I dont know if I can trust it honestly
03:45:26 <rust_collector> but at least it will show 9.18 every time?
03:46:08 <Lemon> it shows 9.13 now
03:46:12 <Lemon> nah I dont trust it
03:46:40 <Lemon> ha 9.20 steady now
03:46:57 <Lemon> now 9.14
03:46:59 <Lemon> pfrpfrpfrpfr
03:47:41 <Lemon> 9,1932v on the systron
03:48:26 <Lemon> 9,173v on the keithley
03:48:56 <rust_collector> ok, that is it, I am never getting into any kind of presicion anything. I can use those meters, and just put a post-it on it, to cover up any error
03:49:17 <Lemon> I admit its driving me nuts
03:49:21 <Lemon> I need another dmm I guess
03:50:09 <rust_collector> you probably want an uni-t, so you have something that "just works"
03:50:17 <Lemon> noooooo
03:50:20 <Lemon> never !
03:50:42 <rust_collector> you can put it in a box, and only use it to calibrate your other gear. it is ok
03:51:01 <Lemon> argh
03:52:12 <rust_collector> I have to admit that the 830 china meters probably will not do that well enough
03:52:19 <rust_collector> But I do want some anyway
03:53:14 <Lemon> the fluke 101 will be my cheapy !
03:53:23 <Lemon> well I think that is the keithley that is out
03:53:32 <rust_collector> but it will not do current
03:53:48 <Lemon> I tried measuring my cheapo psu, according to other peeps it was kinda precise to 10mv, and I always thought it was out by 20-25 with the keithley
03:53:49 <DHess_US> autoranging used to come with a significant operating life penalty compared to manual ranging. But now manual ranging meters do not run very long on a set of batteries either.
03:53:55 <Lemon> and guess what its almost spot on with the systron
03:54:40 <DHess_US> 30+ years ago, my mutlimeters ran for 2000+ hours on a 9 volt. Now they are more like 400 hours maximum.
03:54:51 <DHess_US> Some are only 200 hours.
03:54:57 <Lemon> battery ? whats that, I know mains, but no battery
03:55:04 <rust_collector> So, I wonder if it is 20ma out across the range, or just at 9v?
03:55:14 <rust_collector> it is true, batteries do exist
03:55:20 <Lemon> its probably 20mv out on all ranges
03:55:49 <rust_collector> if it is, you can probably just adjust that out, right?
03:56:05 <Lemon> yes if im 100% sure
03:56:17 <Lemon> I wanted to build voltage references or get one for that reason
03:57:32 <rust_collector> how "deep" is the keithley? is it old o-scope deep, or is it shorter?
04:06:21 <Lemon> short
04:06:36 <Lemon> its maybe, 30cm deep ?
04:06:45 <rust_collector> hehe. ok
04:06:52 <Lemon> 35-40 for the systron
04:19:51 <rust_collector> https://www.youtube.com/watch?v=6KQ9se5PHQg
04:20:15 <rust_collector> that stuff looks very cool, but I do not understand making music at all
04:20:49 <Lemon> dam son
04:21:00 <Lemon> thats how I picture my future house
04:21:24 <rust_collector> ok, I like holland-land, so, have fun
04:26:15 <Lemon> http://shop.voltagestandard.com/product.sc;jsessionid=EFCFD04FF917893E7EDDCD303B5DB428.p3plqscsfapp004?productId=4&categoryId=1
04:27:35 <rust_collector> did you buy it yet?
04:27:41 <Lemon> nah
04:30:05 <DHess_US> I remember emailing him with some questions.
04:31:34 <Lemon> guess I'll get a fluke 5101b for 2.5k usd
04:32:16 <Lemon> you know im thinking more and more to study metrology
04:32:36 <Lemon> and there maybe I'll be able to get some free adjust/calibrations :> :> :>> wink wink
04:35:26 <rust_collector> you do clearly have some kind of disease. good luck
04:40:26 <Lemon> the only cure is more test gear im afraid
04:42:45 <Lemon> https://www.ebay.fr/itm/LM399H-10V-Precision-voltage-Reference-Calibrated-LM399/254402062436?hash=item3b3b8b6864:g:RtsAAOSwPA1cOaqw
04:42:49 <DHess_US> All you need is one of those LTZ1000Z references off of EEVBlog and a Kelvin Varley divider.
04:43:34 <DHess_US> Ever notice that nobody specifies the non-linearity of their precision multimeter?
04:43:52 <Lemon> hmmm interesting, I do need a bunch of precision resistors to make one ?
04:43:54 <DHess_US> That's why you need a precision divider.
04:44:09 <DHess_US> yup
04:44:10 <Lemon> and yes because I need multiple voltages, to calibrate it right ?
04:44:47 <Ampera> I think I might have made people loose their shit (or maybe I'm losing my shit) for suggesting on the EEVBlog forums that I might want a server.
04:44:47 <EEVBlog> If you keep saying that, I'm gonna hold you upside down and shake you until all the electrons fall out, Ampera!
04:45:12 <rust_collector> eeh, what?
04:45:13 <Lemon> ;o
04:45:35 <rust_collector> why would anyone care if you got a server?
04:45:47 <Ampera> all I asked for was suggestions on the sweet spot for old server hardware, and people, as if someone buying a server was such an extreme concept, started going on about why I didn't need it and should just buy some dinky desktop machine instead.
04:47:11 <DHess_US> The sweep spot for used server hardware is what is available on Ebay.
04:47:34 <Ampera> Yeah but there's a lot of what's on ebay
04:47:37 <DHess_US> If you want to build somethign from desktop hardware, then the sweep spot is Ryzen with a desktop motherboard which supports ECC.
04:47:44 <Ampera> I've been looking at quad socket Ivy Bridge machines
04:47:57 <Ampera> Ryzen is nice, but it's expensive, new hardware is.
04:48:13 <Ampera> and this is intended to be a Xen hypervisor.
04:48:19 <DHess_US> Usually you run out of memory before performance. Ryzen isn't expensive.
04:48:41 <Ampera> It's expensive when the budget is between 600-1000 USD
04:48:43 <DHess_US> The biggest reason to get two or four CPUs is to support more memory slots.
04:48:53 <Ampera> I just want cores, man.
04:51:39 <Ampera> The idea is to be able to have a large number of VMs running, and indeed, a lot of memory.
04:52:03 <Ampera> ECC DDR3 (especially RDIMMs) is piss cheap, and old cores, but a lot of them, is also cheap, and fits with what I want to do.
04:52:13 <Ampera> My applications scale fine across multiple cores, even weaker ones.
04:54:56 <DHess_US> Good candidate for a data center pull. You should be able to find something very good on Ebay made by HP or Dell.
04:55:25 <DHess_US> I don't know about a quad CPU but a dual will be available.
04:55:26 <Ampera> Aye, which is what I've been looking at, but I've been looking at 4x E5 systems around Ivy Bridge, I want to know if there's anything better in that price sweetspot
04:55:55 <Ampera> I've found a 2x2 multi-node server for 600 bucks, 128GB RAM, 6 core E5's, supports up to the 12 core E5's
04:55:57 <DHess_US> You might consider instruction set and what AVX is supported.
04:56:13 <Ampera> This might seem like a stupid question, but why
04:56:29 <DHess_US> Because every series has different AVX support.
04:56:39 <DHess_US> And there are 10+ AVX configurations.
04:56:43 <Ampera> I can understand that, but to what particular significance is that
04:57:08 <DHess_US> Because if it doesn't match your application, then you can't use the later AVX version.
04:57:33 <Ampera> That's why I'm asking, because to the best I understand, what I am doing doesn't require it.
04:57:34 <DHess_US> The AVX situation with what supports what is very screwed up.
04:57:55 <DHess_US> Oh, if you don't need AVX then ignore it.
04:57:57 <Ampera> My current sever solution is Westmere-EP which doesn't have AVX anyways
04:58:15 <DHess_US> But if you can take advantage of AVX, then it is a big performance boost.
04:58:32 <Ampera> Most of what I'm doing is web, email, file, experimental, gaming, and virtual workstation stuff
04:58:52 <Ampera> which tends to not need heavy cores, but likes memory, and being able to have a lot of VMs can be useful
04:59:08 <Ampera> none of that is too fussed about AVX that i know of
05:00:04 <DHess_US> https://pbs.twimg.com/media/DXSRqJXXUAE0s4J?format=jpg&name=medium
05:00:28 <Ampera> oh that looks like a clusterfuck
05:03:43 <Lemon> we are talking about old servers ?
05:03:44 <DHess_US> Someone I know just bought this, https://www.ebay.com/itm/ProLiant-DL380-G7-Server-2x-2-80Ghz-X5660-6C-32GB-2x-128GB-SSD-3x-500GB-High-End/233479026935
05:03:51 <Lemon> I build my current workstation with server parts
05:04:08 <Lemon> ddr4 ecc, two e5 2698v3's QS chips, and so on
05:04:18 <Lemon> for 500 euros or so you can have a beast nowadays
05:04:26 <Ampera> I do have a minor concern about Meltdown having taken performance away from a lot of these machines though
05:04:30 <Ampera> and especially as you go back in time
05:04:32 <Lemon> Id go for a e26XX or v2 max platform
05:05:03 <Ampera> Lemon, that's about where I'm at.
05:05:09 <Lemon> a bi-e5 26XX v2, a bucket of ddr3 ecc
05:05:32 <Lemon> dell r620's or something, idk
05:05:41 <Lemon> but yeah basically whats avalaible on ebay
05:05:52 <Lemon> I went the route of buying pieces by pieces
05:05:59 <Lemon> but I wanted a workstation more than a regular server
05:06:28 <DHess_US> Maybe visit their store. They seem reputable.
05:06:30 <Lemon> playing with 32c64t, a 1080 and 64gb of ddr4 for under 1300 euros is pretty neat if you ask me
05:06:38 <Ampera> https://www.ebay.com/itm/233447794035 Something like this is within the realm of possibility
05:08:53 Join: helpplz ([email protected]) to #EEVblog
05:11:00 <coppice_> AVX and AVX2 aren't too bad, but AVX512 is a crazy mix of options
05:11:43 <coppice_> on the other hand, AVX512 doesn't seem to be working out well for anyone so far

06:35:36 <Lemon> so I read a bit about those Kelvin Varley divider
06:36:03 <Lemon> its pretty interesting and seems doable, if I can a voltage reference for a decent price (to adjust a 5.5 digit dmm, should be alrightly priced)
06:36:09 <Lemon> but it seems I need a null detector
06:37:33 Join: helpplz ([email protected]) to #EEVblog
06:40:21 <DHess_US> null detectors were replaced with differential voltmeters.
06:40:42 <DHess_US> In practice you can use any high impedance voltmeter as a null detector.
06:49:48 <Lemon> ho well thats fine then
06:49:57 <Lemon> my new systron donner got 1Gohm input impedance
06:50:11 <Lemon> btw thats normal that it builds up voltage when measuring nothing ?
06:50:20 <Lemon> it seems to top at 0.6528v right now
06:51:02 <Lemon> on the 10v range

07:05:22 <Lemon> hmmm if I understood it well
07:05:39 <Lemon> a KV-D doesnt even need tight tolerance resistors, as long as you find matched ones
07:05:46 <Lemon> well it surely helps, but 0.1% would be fine
07:12:15 <steve30> Lemon, yes, perfectly normal for it to build up voltage when open circuit
07:12:51 <Lemon> alright then perfect, it was just strange for me as my keithley isnt doing it, but it as a 100x times lower input impedance
07:14:27 <steve30> A very high input impedance will pick up things like noise and charge up the input capacitance. Due to the really high impedance, there's nowhere for it to go. On a 10M input impedance though, the input capacitance would discharge into the 10M impedance.
07:15:05 <Lemon> thats what I ended figuring up ! but thanks, I thought something was wrong with my new toy :>
07:15:18 <Lemon> im looking at kelvin varley dividers right now
07:38:26 <DHess_US> I guess technically a null meter doesn't need to be high impedance since at null, there is no current flower.
07:38:45 <DHess_US> That is why mechanical ones work so well in bridge measurement circuits like impedance bridges.
07:38:52 <Lemon> is it buildable ? or should I aim for a cheap used one
07:39:07 <Lemon> I thought about getting one of those HB wheatstone bridges too
07:39:11 <Lemon> or build one, idk
07:39:33 <Lemon> my goal is to have my best current dmm adjusted/calibrated
07:39:45 <Lemon> to be at least sure of one source, then adjust the others
07:39:57 <DHess_US> I have a pair of ESI impedance bridges. They are good to 3 significant digits or 0.1%
07:39:57 <Lemon> I see I can buy a voltage ref on ebay for not too much
07:40:34 <Lemon> what ESI stand for ?
07:40:47 <DHess_US> Electro Scientific Instruments?
07:40:57 <Lemon> ho its a brand ! o k
07:41:02 <DHess_US> They made KVDs also. I have one
07:41:17 <Lemon> do you think its viable to build a KVD myself ?
07:41:21 <Lemon> or it will be too costly
07:41:31 <Lemon> I looked at it, theres no much honestly
07:41:39 <Lemon> I got to match some resistors the best I can
07:41:47 <DHess_US> https://www.ebay.com/itm/ELECTRO-SCIENTIFIC-DEKAPOT-CA-1178-KELVIN-VARLEY-DIVIDER-IN-10-k-OHMS-RESISTANCE/233390730635?hash=item36572bed8b:g:86QAAOSw-qldwHvb
07:42:00 <DHess_US> Oh, absolutely viable.
07:42:16 <Lemon> beautiful device
07:42:17 <DHess_US> Especially since you only need to *match* resistors and don't need absolute accuracy.
07:42:30 <Lemon> so from what I understood
07:42:39 <Lemon> I can get 1% resistors, instead of 0.1 ?
07:42:46 <Lemon> it doesnt matter much as long as I match them, right ?
07:43:10 <DHess_US> Yes ... but ... 0.1% resistors aren't that much more expensive.
07:43:25 <Lemon> well in fact quite a bit, I mean
07:43:31 <Lemon> if I need, approx 7X resistors
07:43:34 <Lemon> for the whole KVD
07:43:40 <DHess_US> But the cost isn't significant compared to the switches and stuff.
07:43:42 <Lemon> I need to get some bags of each values
07:43:51 <Lemon> ho I can go with jumpers no ?
07:43:57 <rust_collector> you probably need resistors later
07:43:59 <Lemon> I don't care if its convenient
07:44:07 <DHess_US> Yea, also consider a harmon divider if you want to do that.
07:44:22 <Lemon> grrr I have to look on google harmon divider now :>

07:46:01 <Lemon> this good old hoffman
07:46:05 <Ampera> there's something neat about using xorg as one fancy terminal multiplexer
07:46:06 <Lemon> I was reading some stuff about him
07:46:17 <DHess_US> http://conradhoffman.com/MML%20files/3_kvd_p3.jpg
07:46:55 <Ampera> I'm on my iBook G4, and I think I'm gonna try to change the resolution in the vtty
07:47:07 <Lemon> thanks a lot, im going to read it
07:47:32 <Lemon> if I can adjust my 5.5 digit dmm, and the 4.5 keithley along with others, i'd be really happy
07:49:50 <Lemon> a wheatstone bridge seems to be a nice thing to have
07:50:02 <Lemon> or build
07:50:27 <Lemon> hmmm maybe buy as it needs some sort of analog meter
07:50:42 <Lemon> I like those HB ones, but im afraid matched resistors in it could drift
07:50:55 <Lemon> those are 70-80 y;o devices
07:54:02 <Lemon> tha hamon method is really brilliant
07:54:53 <rust_collector> I am so confused. I am watching a guy cook paprika chicken, you people talking about resistors, and the wife is nagging in general
07:57:21 <Antarez> story of my life
07:57:25 <Lemon> haha yeah, suumms my life
07:57:54 <Lemon> that systron donner was really a dope deal honesly
07:58:01 <Lemon> honestly
07:58:08 <Lemon> I already love it, with its big bright disply
07:58:12 <rust_collector> it didn't even have to work, but that is a nice bonus
07:58:25 <Lemon> for 43 euros with shipping yeah
07:58:36 <Lemon> tommorow I might get the wavetek !
07:58:45 <Lemon> thats why I like pickup deliveries
07:58:49 <Lemon> you can get stuff on sunday morning
07:59:44 <rust_collector> you can probably meet a lot of people with the same disease if you hang around the pickup spot
08:00:21 <Lemon> ho just people with other disease, like the one who buy for 100 euros of scratching tickets a day
08:00:30 <Lemon> scratching tickets ? is that the right word ?
08:00:47 <Lemon> you know you use a coin to see if you won enough to pay for the next row
08:00:59 <rust_collector> sure
08:01:13 <rust_collector> I am not sure what they are called, but
08:01:55 <rust_collector> well, that is too bad for the guy, he will have dementia in not too long
08:03:02 <Lemon> ho its so common here
08:03:07 <Lemon> tons of peeps in fact
08:03:20 <Lemon> they spend their paycheque on those devil tickets
08:03:43 <Lemon> once or twice a year I buy a 1 euro one with my cigs, win 1 euro, take another, lose, go meh and thats it

08:32:08 <Lemon> im playing the 'lets see where I will burn my money next' game
08:32:19 <Lemon> seems it will be something I will build this time :>
08:32:20 <rust_collector> Oh, I know that
08:32:24 <Lemon> close to the resistor box in fact
08:32:28 <rust_collector> good!
08:32:40 <Lemon> it was the first thing I wanted to build
08:32:47 <Lemon> something to calibrate mah stufff
08:34:51 <rust_collector> you know, if you did what I do, and only buy cheap crap meters, you will never have one go out of spec, because the specs are sort of like: will probably turn on most of the time
08:35:01 Join: helpplz ([email protected]) to #EEVblog
08:35:40 <Lemon> yeah I thought about that
08:35:46 <Lemon> thats what I like in analog meters in fact
08:36:03 <Lemon> as long as they somewhat hit the digit I want them to hit, its fine
08:36:19 <Lemon> but now that I have a dmm that can display 6 digits at once, I want them to be perfect :>
08:36:42 <rust_collector> just put a sticker on it, to cover up the last 3
08:37:08 <Lemon> sorry, I can't do that
08:37:47 <rust_collector> come on Hal! why are you like this?
08:38:30 <Lemon> haha high five
08:38:42 <Lemon> there was a quake 3 player, named hall9000
08:38:59 <Lemon> I never saw someone with such a high level, in any game
08:39:22 <Lemon> you can check it, type cpma hal9000 in youtube and you should find a video, where he reck some peeps
08:39:30 <Lemon> he makes them look like shitty bots
08:39:34 <Lemon> where most of them are top players
08:40:22 <rust_collector> meh, I do not play games
08:41:05 <Lemon> its just impressive to watch
08:41:17 <Lemon> such decisions etc, really insane
08:41:40 <Lemon> pre-shotting rockets where the poor dude havent even spawned yet
08:42:04 <Lemon> I had the chance to play with him once
08:42:17 <Lemon> he had a server named like 'duel me if you can' or some shit like this in bulgarian
08:42:28 <Lemon> he quitted after the score was like 20/-2
08:42:51 <Lemon> yeah you can easily kill yourself while trying some rocket jumps
08:43:00 <Lemon> yes I had a negative score
08:43:16 <Lemon> it lasted a solid 4 minutes I think
08:43:28 <rust_collector> best 4 minutes
08:43:35 <Lemon> yeah that was dope
08:43:58 <Lemon> he told me some tricks on the map, that I never managed to do

09:30:05 <Halcyon> Hey Ampera :)
09:35:41 <Lemon> https://www.ebay.fr/itm/LM399H-10V-Precision-voltage-Reference-Calibrated-LM399/254402062436?hash=item3b3b8b6864:g:RtsAAOSwPA1cOaqw
09:35:49 <Lemon> do you know if those kind of reference are interesting ?
10:00:44 <Ampera> you still there, Halcyon?
10:01:33 <Halcyon> Yep
10:01:35 <Halcyon> What's doing?
10:01:41 <Ampera> blech'
10:02:22 <Halcyon> *cuddles*
10:02:23 <Ampera> I feel like shit, but otherwise I'm alright
10:02:31 <Halcyon> You sick?
10:02:49 <Ampera> no, I'd say I'm depressed, but that would imply I have depression, which I don't believe I have
10:02:56 <Ampera> so I'll just say I have Ampera syndrome
10:03:09 <Halcyon> You can be depressed and not have depression
10:03:48 <Ampera> that's some pretty good logic there
10:05:01 <Ampera> https://www.ebay.com/itm/233447794035
10:05:05 <Ampera> what do you think of this server
10:05:26 <Halcyon> Very nice
10:05:29 <Halcyon> I like the HP servers
10:05:38 <Halcyon> And IBM, they are the two I would buy
10:06:11 <Halcyon> No idea how noisy it will be though? I suspect it won't be quiet. Not sure if that matters?
10:06:12 <Ampera> That's at the tippy tippy top of my price range, but it looks about what I'd want, and it comes with a good amount of memory
10:06:30 <Ampera> I've had high end, high noise IBM servers before
10:06:31 <Ampera> we can deal
10:07:01 <Lemon> you can find some fan replacement, thats acceptable

10:07:19 <Halcyon> Some lazy prick didn't bother to unscrew the drives from the trays when they got rid of them
10:07:43 <Ampera> I'm still looking, though
10:08:10 <Halcyon> When I get back from grocery shopping, I'm going to spin up another hypervisor
10:08:34 <Ampera> I'm about to start experiments on Xen setups
10:08:39 <Ampera> so I'll see how that works
10:08:42 <Halcyon> *nod*
10:09:16 <Halcyon> I looked at XCP-NG + Xen Orchestra, it doesn't really offer anything on top of what Proxmox does, so I don't think I'll bother with it.
10:09:44 <Ampera> Like everything (except for my router) I'll be spinning it up by myself
10:09:50 <Ampera> I'm planning on using a FreeBSD dom0
10:10:20 <Halcyon> Anyway I'll be back in about 45 minutes
10:10:24 <Ampera> k
10:20:11 <rust_collector> servers should have a hot dog grill built in.

10:20:53 <Lemon> ho theres one hidden in fact
10:21:15 <Lemon> its under heatsinks, a small square chip
10:21:24 <Lemon> sometimes theres two, or even more
10:21:43 <rust_collector> do you mean the thin bacon strip rack, just before the fans?
10:22:18 <rust_collector> so, if I take the baco nack off, I can heat hotdogs?
10:22:28 <rust_collector> bacon rack
10:22:33 <Lemon> exactly yes
10:22:39 <rust_collector> ah, cool
10:22:41 <MrMobodies> Just looked above, that server looks beautiful.
10:22:53 <MrMobodies> Oh hello my scrolling bar stuck
10:22:53 <EEVBlog> Hello there, MrMobodies!
10:23:01 <rust_collector> yes, it is the dell servers that look weird
10:23:06 <rust_collector> hah
10:23:11 <MrMobodies> I thought it was a HP
10:23:27 <MrMobodies> but I had a Dell once that kept on nagging me
10:23:29 <rust_collector> yes, which is good, because the dell is the one who look weird
10:23:38 <MrMobodies> until I found a good enough used battery for the raid controller
10:24:08 <MrMobodies> My HP G5 dl380 didn't nag and paused at every bootup about a dead raid battery.
10:24:30 <MrMobodies> I was trying to make is saleable
10:24:59 <rust_collector> I guess there is a good reason why it would be nagging about that?
10:25:25 <MrMobodies> I think for write cache
10:25:43 <MrMobodies> but I had press a key to resume bootup
10:26:23 <MrMobodies> I found one on Ebay that worked, I think it was a lithium
10:26:56 <MrMobodies> I don't mind messages at boot and even beeps but not it stops on it
10:28:32 <Lemon> I get a series of beeps on mine
10:28:37 <Lemon> but I cant figure why
10:30:23 <MrMobodies> but it turns on?
10:31:55 <MrMobodies> oops I mean works normally
10:33:03 <Lemon> yeah works perfectly fine
10:33:32 <MrMobodies> Just noticed "<EEVBlog> Hello there, MrMobodies!" the EEVblog bot now greets me.
10:33:39 <MrMobodies> thanks
10:33:53 <MrMobodies> I know some where I don't have the video card connected
10:34:04 <MrMobodies> beeeeep beep beep beep beep
10:34:22 <MrMobodies> I don't need some of them connected up to a screen
10:45:01 <MrMobodies> Talking of Dells, I remember when some of their stuff had PSU's with a 12/5v rail non standard but on an ATX plug
10:45:19 <rust_collector> yep
10:45:47 <MrMobodies> I had to be extra careful to read the labels
10:46:06 <rust_collector> I wonder if I should put together a desktop based little crap server, just because I probably have all the things laying around
10:46:30 <MrMobodies> some pictures would be nice as well
10:46:42 <Lemon> I think im at a pivot point
10:46:54 <Lemon> and I should stop seeking perfection right now before its too late :>
10:47:16 <Lemon> because theres no perfection
10:47:27 <rust_collector> join me here in the land of mediocre stuff, it is just about ok here
10:47:27 <Lemon> and I know myself well, I will never stop seeking it
10:47:41 <Lemon> haha honestly I wish I could do it !
10:47:45 <MrMobodies> I tried to achieve perfection... sometimes it doesn't last long
10:47:46 <Lemon> but something in me wants that perfection
10:48:04 <MrMobodies> I try to make it as perfect as I can
10:48:08 <Lemon> it was the same with rubiks, I wanted the very best, ended up with multiple cubes of every avalaible models
10:48:28 <Lemon> tuned them for hours, to have the best possible stuff
10:48:35 <rust_collector> If you have to have perfection, get into measuring physical things. roundness, flatness, straightness...
10:48:49 <Lemon> dont start me on another thing please
10:49:18 <rust_collector> sorry, but it is the only true thing
10:49:22 <rust_collector> I mean.
10:49:22 <MrMobodies> I had the same problem with my spectacles 15 years ago trying to get them clean
10:49:32 <MrMobodies> without the smears
10:49:45 <rust_collector> heh
10:49:49 <MrMobodies> changing the plastic lens to glass solved that problem
10:50:23 <MrMobodies> I was trying to achieve perfection by cleaning the lens, where I spent hours and hours
10:50:45 <MrMobodies> but it was the plastic that I found made it difficult to achieve that pefection
10:51:03 <rust_collector> did you try to just run them thru the dishwasher?
10:51:29 <MrMobodies> No, I used a certain type of tissue, back then which sort of worked but the smears show,
10:51:51 <MrMobodies> with glass, washing up liquid and a high pressure blast under hot water
10:52:09 <MrMobodies> and if I want it perfect where I don't see the water marks, I can use the Data Vac
10:52:15 <MrMobodies> to blast the water drops off
10:55:16 <MrMobodies> I don't mind marks and dust here and there but I can't stand smears in my vision
10:56:24 <rust_collector> I tried to cut out a tiny cellotape... I think it was a moose, to stick on dads glasses, but... I don't think I ever got that done
10:59:04 <MrMobodies> Cut around a piece of tape to make it the same shape as an animal and stick it on his glasses
10:59:32 <MrMobodies> A prank?
10:59:40 <rust_collector> yeah.
11:00:33 <MrMobodies> I wondered about make it look like the lens was cracked
11:01:13 <rust_collector> it did work well on the overhead projector, cutting out small figures and taping them to the sens
11:02:11 <rust_collector> yeah, the broken glass version could work, just make sure people don't get angry, and throw them to the ground, so they break, then they figure out they were not

11:02:40 <Lemon> but I dont want to spend a ton on calibration stuff
11:02:47 <Lemon> I see where this is heading
11:02:49 <rust_collector> yes, sure
11:02:52 <Lemon> I just want to trust the stuff I have
11:03:04 <Lemon> no im serious I'd rather get other pieces of gear I dont have
11:03:31 <rust_collector> nah, forget it, what do you "need" now? you have all the things
11:03:32 <MrMobodies> K1 seems to be unpopulated
11:04:19 <Lemon> well maybe not need, but new stuff to play with :>
11:04:36 <Lemon> or just components to make things
11:04:41 <MrMobodies> and fiddle with
11:05:08 <rust_collector> sure, but maybe try to make use of your stuff now that you have it, not just collect more. You can buy stuff when you figure you need it for something
11:05:29 <rust_collector> you need 2.7 months off from buying things
11:06:08 <rust_collector> only components, no devices for 2.7 months
11:06:09 <MrMobodies> Don't want to be a hoarder just yet or may not have any room for the serious stuff.
11:06:52 <Lemon> yeah thats true but well, im a born hoarder
11:07:04 <Lemon> but yeh I should make things now
11:07:06 <rust_collector> he is a hoarder, and he knows it. so we have to keep him away from ebay and the french site for some time now
11:07:10 <Lemon> I dont have much excuses
11:07:24 <Lemon> but that Vref you know.....
11:07:29 <Lemon> arghhh
11:07:29 <rust_collector> mmhmm
11:08:48 <rust_collector> what components do you need for that?
11:08:56 <Halcyon> Back Ampera
11:09:27 <Lemon> well honestly, buying one calibrated/adjusted is a better bet
11:09:38 <Lemon> but the divider, I can make it
11:09:42 <rust_collector> ok, how much is that?
11:09:56 <Lemon> I linked it earlier, 50 euros with shipping
11:10:15 <rust_collector> oh, the stick-looking board?
11:10:19 <rust_collector> 399
11:10:20 <Lemon> 0,003% + 0,0004% 1 year
11:10:23 <Lemon> yeah
11:10:41 <Lemon> that would be fine to see how accurate my stuff is
11:11:01 <rust_collector> ok, but that is the last thing, until the 16th of may
11:11:08 <Ampera> Hi Halcyon
11:11:09 <Lemon> may ? ??>???
11:11:14 <Lemon> but its like, in 2 years man !
11:11:20 <rust_collector> 2.7 months from now
11:11:22 <Lemon> maybe 3
11:11:50 <rust_collector> I would put ebay and leboncoin in your hosts file, so you do not see itm
11:12:22 * Ampera pokes Halcyon

11:12:56 <Halcyon> *sproing*
11:13:31 <rust_collector> did you people develop an alternative language?
11:15:26 <Lemon> it seems yeah
11:15:33 <Lemon> but we will develop ours, dont worry
11:15:34 <rust_collector> neat.
11:15:45 <rust_collector> I do worry, but that is ok
11:16:17 <Lemon> we will see that on next adventures, for now I need to rest
11:16:22 <Lemon> my little brain is tirered
11:16:28 <MrMobodies> I know of a language
11:16:35 <MrMobodies> it is called "sign language"
11:16:58 <MrMobodies> where you sign a contract whether you read it or not
11:17:10 <MrMobodies> that's just a joke
11:18:06 <MrMobodies> what happens when someone goes bankrupt?
11:18:32 <MrMobodies> they send the poltergeists out to reposess their homes
11:18:45 <MrMobodies> and the practitioners come out
11:19:01 <MrMobodies> to find out what they want
11:19:23 <MrMobodies> and how to pay of the creditors
11:20:08 <MrMobodies> The wind is very strong out there at the moment
11:20:36 <rust_collector> same here. the lights have been blinking a bit again
11:20:51 <Lemon> heh for once its alright there
11:20:54 <Lemon> ok I got to sleep
11:20:54 <MrMobodies> I was at the local village pub
11:20:58 <Lemon> see you peeps take care
11:21:04 <rust_collector> good night
11:21:05 <MrMobodies> nighty
11:21:36 <MrMobodies> in the toilet I saw the street lamp flicker
11:21:55 <MrMobodies> trees branches in the way? no, the pole was moving a lot
11:22:04 Quit: Lemon ([email protected]) Connection closed
11:22:39 <Halcyon> rust_collector: No, just giant nerds :P
11:23:00 <MrMobodies> I feed the birds every morning
11:23:01 <rust_collector> I like your thing with going to the pub. That is pretty much not a thing here. We used to go visit people, maybe pop over to the neighbor... but that has almost stopped as well
11:23:25 <MrMobodies> It is a tiny little village pub
11:23:31 <rust_collector> 6'7" nerds
11:23:36 <MrMobodies> like a public house
11:23:49 <MrMobodies> the locals go there
11:24:00 <rust_collector> well, yes. and that is nice. locals do not go anywhere here
11:24:47 <MrMobodies> There are two pubs, a new one across the road and an old one built in the 18th century which I like
11:24:52 <MrMobodies> wooden floors,
11:25:03 <MrMobodies> minimal lights in there
11:25:29 <MrMobodies> Everyone knows one another in this village
11:25:53 <MrMobodies> one person says something and the barman broadcasts it to everybody
11:26:44 <MrMobodies> I only go there to get some diet coke or water
11:27:03 <MrMobodies> and some crisps but then the dog tried to tickle me with it's paws as it stands up
11:27:31 <MrMobodies> it loves crisps
11:27:58 <rust_collector> it used to be like that here as well, but we used to meet in the local store. I guess the old people go to church, i think it is on thursdays, to eat waffles and chat
11:28:23 <MrMobodies> there are lots of middle and old age people there
11:28:29 <MrMobodies> with dogs
11:29:11 <MrMobodies> waffles that snice
11:31:52 <rust_collector> waffles are always nice

12:13:40 <helpplz> omg thx team my LPF works great :D
12:13:56 <helpplz> my head phones rattle now :D
12:13:57 <Halcyon> Woot
12:14:35 <rust_collector> hmm, so now you need to fix your head phones... great
12:14:59 <helpplz> well not yet they dont clip
12:15:25 <helpplz> thers a little hiss i would like to take out but for now im happy asf
12:15:59 <rust_collector> just pretend you have a slight tinnitus, and ignore it
12:16:26 <helpplz> xD yah when you crank it up you cant really here it any way
12:17:17 <rust_collector> and if you really crank it up, you will really have tinnitus, so it is a problem that will fix itself
12:17:30 <helpplz> xD
12:17:53 <helpplz> it doesnt really hurt my ears cuz the LPF i put on it
12:18:17 <helpplz> I think its safe to say Im a Wizard
12:18:23 <rust_collector> ok
12:19:22 <rust_collector> some of us are all the wizards
12:19:49 <helpplz> question tho if i put more DC amps (serial 18650) to a tda2822m will it get louder?
12:20:43 <helpplz> cuz it has a verifiable DC voltage input ... wait i mean if i raise the voltage not the amps
12:21:08 <rust_collector> how many volts do you give it now?
12:21:12 <helpplz> 4
12:21:41 <helpplz> i think it max tolerance listed was 12vdc
12:22:44 <rust_collector> it is rated to up to 15v, (st)
12:23:16 <rust_collector> from what I can see in the datasheet, it will give a bit more power if you up the voltage
12:23:40 <helpplz> so lets say ... cuz i have it hooked up to two 18650's in parallel ... i switch it to serial ... well it get louder
12:23:51 <rust_collector> yes
12:24:17 <rust_collector> as long as the circuitry around it can handle it
12:24:26 <rust_collector> which I guess it can, at that level
12:24:36 <helpplz> hmm ok ... well not right now but i will later
12:24:46 <helpplz> good to know tho thx
12:25:39 <rust_collector> if you look in the datasheet, you have some ratings for power output, and it is different at different voltages, so it will make some difference
12:26:09 <helpplz> k ima check the datasheet
12:26:48 <rust_collector> https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=2ahUKEwiG_P-M9NTnAhWL-ioKHTeiCi4QFjAAegQIAhAB&url=https%3A%2F%2Fwww.st.com%2Fresource%2Fen%2Fdatasheet%2Fcd00000134.pdf&usg=AOvVaw0CPQ-Drs676-kIojX99gex
12:27:00 <helpplz> awsome
12:29:58 <rust_collector> The original ST parts (now obsolete) claimed an Absolute Max of 15v, and also gave that as the maximum operating voltage. This agrees with the specs for the NJ2073D and NTE7155 clones. So running it at 12v should be legal, though nowhere else in the ST datasheet is there mention of operation over 9 volts. A bit of a red flag. ST continues to build the SOIC8 variant, the TDA2822D.
12:30:21 <rust_collector> I guess 2 in series would be good enough
12:30:35 <rust_collector> it is much more than 4v
12:36:25 <helpplz> cool thx for the help :)
12:37:47 <rust_collector> I guess, when the battery is low, it would be around 3v, which is not much
12:37:57 <rust_collector> have fun, I am going to bed
13:19:32 <MrMobodies> I heard news that Microsoft made a copy of Chrome for their Edge browser
13:19:45 <MrMobodies> I took a look and I see they got rid of that blue bar in settings
13:19:47 <MrMobodies> https://i.imgur.com/3Ce2B0K.jpg
13:20:04 <MrMobodies> that doesn't flash/blink as well on new opened tabs.
13:25:43 <DHess_US> Yes, Microsoft Edge is now based on Chrome.

22:14:52 <Ysjoelfir> hoi
22:14:56 <Lemonizer> oi oi
22:15:05 <Lemonizer> how you doin ?
22:15:20 <Ysjoelfir> oh no, its the Watermelonizationer! :D I'm more or less repaired again
22:15:35 <Ysjoelfir> a bit slime in the throat, but besides that I'm feeling fine
22:15:39 <Lemonizer> hehe :> great news !
22:15:41 <Ysjoelfir> I already worked on my WW2 Radio today :)
22:15:44 <Ysjoelfir> And how are you?
22:16:25 <Lemonizer> I want pictures ! well im doing good, and I love my new dmm ! I was looking at a somewhat cheap voltage reference to check my dmm's, like this one https://www.ebay.fr/itm/LM399H-10V-Precision-voltage-Reference-Calibrated-LM399/254402062436?hash=item3b3b8b6864:g:RtsAAOSwPA1cOaqwhttps://www.ebay.fr/itm/LM399H-10V-Precision-voltage-Reference-Calibrated-LM399/254402062436?hash=item3b3b8b6864:g:
22:16:26 <Lemonizer> RtsAAOSwPA1cOaqw
22:16:43 <Lemonizer> because theres 20mv difference between my 175 and the systron, I think the 175 is out of cal
22:16:55 <Lemonizer> https://www.ebay.fr/itm/LM399H-10V-Precision-voltage-Reference-Calibrated-LM399/254402062436?hash=item3b3b8b6864:g:RtsAAOSwPA1cOaqw
22:16:58 <Lemonizer> sorry better link
22:17:53 <Ysjoelfir> that could well be the case. LM399 is absolutely enough for the systron donner. I for myself am building a variable voltage reference, but I got somehow annoyed with it...
22:18:25 <rust_collector> hola
22:18:51 <Ysjoelfir> regarding pics of the radio: I thought about creating a thread at eevblog so that more people could follow the restauration. but I am a bit scared because of all the swastikas and Reichsadlers that are scattered on that radio. I'm sure someone will be offended by it.
22:21:53 <Lemonizer> boarf its alright
22:21:57 <Lemonizer> hey rusty
22:21:58 <rust_collector> it is ok to be offended
22:22:12 <Lemonizer> and I'll maybe buid a hamon divider
22:22:20 <rust_collector> hah
22:22:35 <Lemonizer> if I buy bags of 1% resistors, I can find some matched ones with 0.001% tolerance or so
22:22:52 <Ysjoelfir> hi rusty
22:22:52 <Lemonizer> brb guys gotta eat
22:23:37 <Ysjoelfir> sure it is ok. but the quastion is: how much offense will be created by that? some people don't understand that collecting stuff doesn't mean living that way of thinking.
22:24:09 <rust_collector> well, is that your problem, really?
22:24:14 <Ysjoelfir> I would start with .1% Lemonizer, that would be easier :) and potentially cheaper
22:24:34 <Ysjoelfir> I fear that it could very quickly become my problem
22:24:46 <rust_collector> yeah, get better ones, so you don't have to find a use for 98% of them for something else later
22:25:00 <coppice_> Lemonizer: if you find some resistors within 0.001% they will only be that accurate at one VERY specific temperature. 1% resistors are just not made with a low enough temp coefficient to be useful as 0.001% resistors
22:25:31 <rust_collector> ok, well, then just forget about it. enjoy your radio
22:26:32 <coppice_> and they will age as well
22:29:35 <rust_collector> the time is now, and I am cooking pasta.
22:30:07 <rust_collector> I am not sure what I will do to it, but it will be some kind of dish with pasta in it
22:31:20 <Ysjoelfir> just toss some gorgonzola in it, a bit cream, garlic and sauted onions, and youre done
22:34:38 <rust_collector> yeah, that sounds nice.
22:34:47 <rust_collector> I won't do that, gut...
22:34:50 <rust_collector> but
22:40:37 <Ysjoelfir> why not?
22:41:08 <Ysjoelfir> while researching the... "allowedness" of displaying said symbols I found out that a ancient nordic/germanic rune is also a prohibited sign in germany oO
22:41:44 <rust_collector> because I do not have godzillacheese or cream, lol
22:42:18 <rust_collector> yeah, it is a "neo-nazi" sign,
22:42:36 <rust_collector> I know they react badly to our flag also
22:43:00 <Ysjoelfir> ok, that is a legit reason^^
22:43:04 <Ysjoelfir> they do? why that?
22:43:15 <rust_collector> nazi stuff... I dunno?
22:43:47 <rust_collector> none of these things have anything to do with anything, so...
22:44:22 <rust_collector> it is just that someone feels offended, and people say that we can not let these people be offended, so we will make everything illegal
22:45:06 <Ysjoelfir> that is sadly true.
22:45:39 <rust_collector> there was a clothing brand that used norwegian flags on their jackets, and... I don't know how that ended, but ther was a lot of stuff in the news about it
22:46:22 <Ysjoelfir> strange. I don't understand that, what has the norwegian flag to do with any kind of radicalism?
22:49:16 <rust_collector> yes?
22:49:36 <rust_collector> oh well
22:53:20 Quit: helpplz ([email protected]) Quit: http://www.kiwiirc.com/ - A hand crafted IRC client
22:58:47 <rust_collector> I wonder if I should start to do a lot of bad stuff, start a group of weirdos, that can do bad things, just to see if we can make the irish flag illegal
23:03:07 <Ysjoelfir> XD that would be interesting. and I'm pretty sure one could succeed with that without any problem
23:08:45 <rust_collector> so, on my bench... I have a piece of "wood" with a 14 pin chip glued to it. I wonder what I was doing there
23:19:20 <Ysjoelfir> oO that is indeed a good question
23:20:09 <Ysjoelfir> but good to know that I am not the only one to find sometimes very strange things and standing in front of them like ".....dafuk was I doing there?"
23:20:27 <rust_collector> yeah

23:22:49 <rust_collector> always good, when you are in the hospital to undo your clever idea that went wrong, to see some guy with cancer who was shot with a cannon. at least then you realize it could be worse
23:23:10 <Ysjoelfir> true indeed
23:26:10 <rust_collector> heh, I remember this little kid and his mom sitting in the waiting room, the kid had a wood splinter in his finger. So here I come with blood all over my face. I think they sort of felt they should let me go in first, but they did not want that, so they just sat there, trying to not look, lol
23:26:59 <rust_collector> aah, the good old times.
23:30:03 <Ysjoelfir> lol^^ what did you do that you were that messy?
23:32:18 <rust_collector> uhm, I was at a party, at a farm I used to hang at. So, this guy I went to school with was there, and his sister threw a bottle, and hit me in my right eyebrow, which just split open. That was sort of fun, because she said she was rtying to hit this other guy, which was sitting almost next to her.
23:33:55 <rust_collector> then the guy I was sitting next to said "you should go look in a mirror"
23:33:58 <rust_collector> heh
23:38:51 <Lemonizer> hello I need some advices to buy a new dmm
23:38:51 <EEVBlog> Hello there, Lemonizer!
23:39:00 <Lemonizer> wow I triggered it for the first time
23:39:08 <Lemonizer> im proud
23:39:10 <rust_collector> oh crap, it is THAT guy
23:40:05 <steve30> hello Lemonizer
23:40:18 <Lemonizer> :>
23:40:22 <Lemonizer> hello steve
23:40:49 <Ysjoelfir> lol. so nothing tooo bad rusty :)
23:41:16 <Lemonizer> http://conradhoffman.com/MML%20files/1_vref_p4.jpg I learnt some valuable things there
23:41:18 <rust_collector> no, but it did look pretty horrible until they stitched it up
23:42:16 <Ysjoelfir> I'm still searching for a law or juris...thing that tells me that I can not get sued for showing a photo of that damn radio. instead I find things like "the church decided 2017 to destroy all church bells that were made in the nazi time and cast new ones"....
23:42:28 <Ysjoelfir> I assume so. cut flesh always look... nasty
23:42:48 <rust_collector> white t shirts full of blood makes it look worse
23:43:00 <Ysjoelfir> lol :)
23:43:05 <Lemonizer> just put the picture into a spoiler, and tell people about it
23:43:07 <Lemonizer> that will be fine
23:43:15 <Lemonizer> you'll always find whinny bitches anyway
23:43:32 <rust_collector> so, Lemonizer what sort of meter are you looking for this time?
23:43:41 <Lemonizer> ho nothing it was a joke
23:43:50 <Lemonizer> theres no much on leboncoin
23:44:05 <rust_collector> no, seriously... what are you looking for?
23:44:10 <Lemonizer> a null meter would be interesting, aswell as a wheatstone bridge
23:44:15 <rust_collector> hah
23:44:28 <Lemonizer> ho Ysjoelfir, do you have some HB wheatstone bridges ?
23:44:34 <Ysjoelfir> nope
23:44:43 <Lemonizer> I wonder if they are still accurate
23:44:44 <rust_collector> or any other bridges to sell?
23:44:57 <Ysjoelfir> but I have a bridge from another manufacturer that I never tried
23:45:05 <Lemonizer> theres one for sale for 24.5 euros with 13 euros shipping on the equipement website from nl
23:45:16 <Ysjoelfir> I could sell that, after I took a look inside for a video, sure
23:45:26 <Lemonizer> https://odnd.nl/lab-equipment/13568-hartmann-braun-pontavi-wheatstone-ohm-meter-no1.html
23:45:34 <Lemonizer> ho yeah im still interested by a list of what you have for sale :>
23:46:28 <Ysjoelfir> i know :)
23:46:42 <Lemonizer> https://odnd.nl/lab-equipment/13561-hartmann-braun-inkavi-eb-41-1-inductance-and-capacitance-meter-no1.html
23:46:46 <Lemonizer> this is interesting too
23:47:11 <rust_collector> many things are interesting...
23:47:17 <Lemonizer> yeah
23:47:45 <Lemonizer> what I want for my lab, is to be able to measure various things, rather than having ultra precise stuff (I'd like too but its too expensive)

23:48:08 <Lemonizer> a lot of nice deals were made
23:49:00 <Lemonizer> I should get a variac and an isolation transformer to
23:49:01 <Lemonizer> too
23:49:13 <Lemonizer> but im just waiting until a nice deal pop
23:50:30 <Ysjoelfir> do you want to have an isolation transformer + varia from me? I am sure I have that flying around
23:51:00 <Lemonizer> depending on how they are and how much you want, that is interesting yes :>
23:51:16 <rust_collector> If I ever visit you, I will bring a helmet
23:51:26 <Lemonizer> haha
23:51:50 <Ysjoelfir> they are good and you could learn something while assembling a unit :) or I could build a complete unit for you if you don't want to do that. but that would be more expensive^^
23:52:14 <Lemonizer> well I like old piece of gear honestly :>
23:52:25 <Lemonizer> but yes I plan to build several things just to learn
23:52:41 <Lemonizer> I like to look at schematics of my gear to see how they work
23:52:44 <Lemonizer> or atleast have an idea
23:54:37 <rust_collector> The annoying thing, is that you think you have a circuit figured out, then an old guy comes and says "yes, that is how it would usually work, BUT in this case, because blahblahblah, it does everything backwards
23:55:04 <Lemonizer> everitiem
23:55:37 <Lemonizer> do you also have a null meter ? Ysjoelfir
23:55:42 <rust_collector> it is just like the pingpongdingdong we used to send fake gps signals to the aliens during the war
23:56:47 <Ysjoelfir> i love when that happenes rusty... :D Lemon: no.
23:56:53 <rust_collector> And THAT, is how we invented the 5g death rays
23:57:14 <Lemonizer> ho yes I wanted to show you that https://www.leboncoin.fr/collection/1569492963.htm/
23:57:18 <Lemonizer> its one strange thingie
