00:02:45 <Ysjoelfir> ^ don't be so greedy. I would totally be happy about having +v. who needs +r anyways.
00:14:56 <Ysjoelfir> I'll be on my way home. cu

03:52:44 <Ysjoelfir> Hi all
03:53:57 <Lemon> hi hi
03:54:47 <Lemon> little question
03:54:53 <Lemon> when measuring a 2.01k resistor
03:55:09 <Lemon> one dmm measure 2.01021k, the other 2.01026k
03:55:12 <Ysjoelfir> yes, buy it.
03:55:21 <Lemon> so they agree within 50mOhms
03:55:32 <Lemon> thats how many ppms ?
03:55:41 <Lemon> 100 ?
03:55:52 <Lemon> or 25 ?
03:55:56 <Ysjoelfir> 1 ppm is 1 part per million. just convert it^^
03:56:33 <Lemon> so 25, right ?
03:57:56 <Ysjoelfir> well, 1 ppm is one milionth. so 25 ppm is 25 millionth. like 0.000000025 (if I counted the 0's correct)
03:57:58 <coppice> 25 parts per million - its why your odds of success as an actor are so bad
03:58:35 <Lemon> 25 ppm on 10 volts is 0.00025
03:58:42 <Lemon> if im right
03:59:03 <Lemon> as my 6.5 digits dmm's last digit is 1ppm
03:59:06 <Lemon> well, I call it like this
04:00:07 <Lemon> so logicaly yes thats approx 25ppm
04:01:31 <Ysjoelfir> btw lemon, did I already tell you that I'll become a IoT wearables nerd?
04:01:49 <Lemon> no but its ok I like those things too :>
04:01:55 * Ampera hugs Lemon and Ysjoelfir
04:01:55 <Lemon> heh I have an og pebble !
04:02:15 <Lemon> hi thugger !
04:02:26 <Ampera> my Pinebook Pro shipped
04:02:30 <Ampera> via DHL
04:03:05 <Lemon> good news :>
04:03:06 <Ysjoelfir> I got myself a danish watch. a Skagen. I like the sound of the name. (no, don't try to pronounce it english!)
04:03:11 <Ysjoelfir> nice Ampera :) and hi
04:03:18 <Ampera> how are you doing Ysjoelfir and Lemon
04:03:39 <Lemon> im ok, seend my dear addictologist and talked a bit, got my meds for a month
04:03:54 <Ampera> addictologist?
04:04:08 <Lemon> is it the right name ? you know doctors who treat addictions
04:04:11 <Ampera> did you finally start going to Test Equipment Anonymous?
04:04:27 <Lemon> hah another addiction sadly ! but this one is ok from his point of view :>
04:04:38 <Lemon> also I want to buy this https://www.ebay.fr/i/401288210270?ul_noapp=true
04:04:48 <Ampera> buh my Windows 10 download is only going at 15GB/s
04:04:51 <Ampera> er, MB/s
04:04:55 <Lemon> no much reasons besides 'damn, 18 precision wirewounds for that price !'
04:05:12 <Lemon> 15 ? thats like, 3--4 times of the best I can achieve
04:05:24 <Ysjoelfir> I'm fine, playing some games soon after I'll be done with the food :D how about you Ampera?
04:05:27 <Ampera> it's like 1/4th of what I can do on a bad day
04:05:32 <Ampera> it's the server end that's slow
04:05:41 <Ampera> Ysjoelfir, I'm alright, it's a slow day at work
04:05:55 <Ysjoelfir> I hate those.
04:05:58 <Ampera> half the people on my team are out today, so not much work is getting done, so I'm spending the time to do some stuff I've been wanting to do
04:06:19 <Ampera> I recently got an MSDN subscription, so I'm going to set up a Windows VM, as I've lost the one I had
04:06:30 <Ampera> then I can do some experiments with SQL Server
04:06:40 <Lemon> Ysjoelfir watcha think of those resistors ? sadly shipping is high... he got a otn of them, various weird values but for some reasons I want them, 10watts 0.1% precision wirewounds are rare
04:07:30 <Lemon> but man even with shipping being 75 percent of the price
04:07:35 <Lemon> 18 resistors !
04:07:38 <Lemon> for 10 euros total !
04:07:44 <Lemon> if shipping wasnt that high I'd buy a ton
04:07:52 <Lemon> for 200 pcs thats 40 euros :/
04:07:55 <Ysjoelfir> I can't read franceish, but it looks like russion resistors. we all love russian stuff!
04:08:05 <Lemon> yeah, 10 watts 0.1%
04:08:08 <Lemon> thats quite uncommon
04:08:21 <Lemon> and I have some nice kelvin clips
04:08:31 <Lemon> bought them for 25 euros, they are really well made for the price

04:11:26 <Lemon> im growing passion for precision resistors
04:11:38 <Lemon> especially old russian ones
04:13:02 <Ysjoelfir> you should start looking into tubes
04:13:25 <Lemon> capacitors
04:13:27 <Lemon> I love capacitors
04:13:30 <Ampera> boob tubes
04:13:33 <Lemon> you have such a lovely collection man !
04:13:37 * Ampera throws a CRT at Lemon
04:13:45 <Lemon> I was like a kid when I saw the bigass one you had :>
04:13:52 <Lemon> I always wanted to get some for various reasons !
04:14:51 <Lemon> I want to get some precision ones too
04:15:16 <Ysjoelfir> I am still looking for a mercury vapor rectifier...
04:15:56 <Lemon> what is it used for ?
04:16:12 <Ysjoelfir> for great looks
04:16:23 <Ysjoelfir> or do you want to know about the original, intended use?
04:16:28 <Lemon> yes :>
04:16:38 <Lemon> im not questionning why you want it
04:16:41 <Lemon> im like that too
04:16:45 <Lemon> I want things, for errr
04:16:48 <Lemon> because !
04:17:45 <Ysjoelfir> I know. I'm just mocking you :P the mercury vapor helps ionizing the gas in the tube which supports the flow of current. with mercury rectifiers you can get way higher currents than with a standard rectifier tube
04:18:02 <Ysjoelfir> they were used eg. in train applications or in big transmitters
04:18:10 <Lemon> interesting ! I need to learn more about tubes
04:19:13 <Ysjoelfir> and they look gorgeous
04:19:14 <Ysjoelfir> https://upload.wikimedia.org/wikipedia/commons/thumb/9/99/Mercury_ars_rectifier_%C5%A0umperk_2.JPG/1024px-Mercury_ars_rectifier_%C5%A0umperk_2.JPG
04:19:32 <Ysjoelfir> thats the mercury glowing
04:19:37 <Lemon> :OOOO
04:19:43 <Lemon> damn yes !
04:19:47 <Lemon> thats really impressive !
04:19:57 <Lemon> but the cost must be as impressive sadly
04:20:08 <Ysjoelfir> yes, they are pretty rare sadly
04:21:01 <Lemon> but about those big caps you have
04:21:05 <Lemon> where did you buy them ?
04:21:13 <Lemon> I looked on ebay but they are hard to come by
04:21:19 <Lemon> I was tempted at a coke can sized one
04:21:25 <Lemon> but it still was 20 euros with shipping
04:21:28 <Ysjoelfir> one of the easiest to find ones should be AX50. they are about 40€ a piece. single phase only and way smaller though
04:21:47 <Ysjoelfir> the high capacity ones? like 6800µF/400V?
04:21:55 <Lemon> the big mofos yeah
04:22:01 <Lemon> beer can sized
04:22:04 <Lemon> or even bigger
04:22:45 <Ysjoelfir> (pic of two AX50s) https://i.ytimg.com/vi/47AmdBG7w_U/maxresdefault.jpg
04:23:30 <Lemon> still lovely !
04:23:32 <Ysjoelfir> the big caps were actually more or less free. like... 20€ for 20?
04:23:40 <Lemon> :OO
04:24:42 <Ysjoelfir> I got them from a forum back then, the good old hifi forum
04:25:54 * Ampera hifives Ysjoelfir
04:26:21 * Ysjoelfir spanks ampera's hand :P
04:26:34 * Ampera launches Ysjoelfir far beyond the sea
04:27:07 <Ysjoelfir> weeeeeeeeeeeeeeeee
04:36:45 <Ampera> At some point I think I'm going to set my IOMMU setup again
04:37:30 <Ysjoelfir> whats that?
04:37:43 <Ampera> It allows me to forward PCIe devices into a VM
04:37:50 <Ampera> so I can use a real GPU inside of a virtual machine
04:37:53 <Ysjoelfir> that sounds usefull
04:38:08 <Ampera> It is, but notoriously quirky, and it's not as simple as just plopping stuff together
04:39:26 <Ampera> I also want to do it when I buy an Epiphan capture card eventually, that way I can composite the output straight into my desktop normally
04:41:15 <Ysjoelfir> that sounds like a great solution :) I like it :D
04:41:19 <Lemon> ha I remember trying that
04:41:23 <Lemon> but I gave up
04:41:38 <Lemon> I think I tried with a type 1 hypervisor or whatever is it called
04:41:55 <Ampera> I also need some solution for keyboard/mouse, synergy/barrier would be fine for most things, but might get a bit difficult with games
04:42:19 <Ampera> Bare metal. I had considered installing Xen on this machine and setting up a multi-OS environment with it, but decided not to
04:46:31 <Lemon> vms are interesting
04:46:41 <Lemon> I like to play around with some obscure os's
04:46:45 <Lemon> not that I really have the use of it
04:47:37 <Lemon> besides a vm that I use when a trashed computer coming from a 'please fix my shit' peep ends here
04:47:47 <Lemon> and I dont want to plague my workstation with it
04:48:21 <Lemon> ysjoelfir a dude sells that https://www.ebay.fr/itm/Precision-Matched-Pair-Reference-Standard-Capacitors-2-2000uF-0-02-Tolerance/264232571376?hash=item3d857d11f0:g:RZEAAOSw7IRchVue and claims it can be used to calibrate lcr meters, but how a matched pair helps ? dont you need a single one ?
04:56:03 <Lemon> hooo I found some caddock 0.1% 10M resistors for a decent price
04:56:12 <Lemon> 20 euros for 10, most of it shipping but well
04:56:28 <Lemon> that decade box will be really nice I swear
05:08:27 <Lemon> also Ysjoelfir you should like that one https://www.ebay.fr/itm/Huge-Thyratron-6A-15000V-15kV-High-Voltage-Tube-Soviet-Triode-New-TP1-6-15/272993659472?hash=item3f8fb0aa50:g:aF8AAOSwkLhaPaG0
05:28:49 <rust_collector> and Ysjoelfir why don't you live in salzgitter, or berlin?
05:29:04 <Lemon> waddup rusty
05:29:38 <rust_collector> uuh, I was on a walk, and went to the store?
05:29:46 <Lemon> nice !
05:29:56 <rust_collector> yes, it mostly was
05:30:30 <rust_collector> so, you want a large-ish cap?
05:30:38 <rust_collector> what is a large cap?
05:30:42 <Lemon> I always wanted big ass capacitors yeah
05:30:58 <Lemon> those which looks like beer cans
05:31:03 <rust_collector> Ok, I just have cylinder shaped ones
05:31:11 <rust_collector> no ass shaped ones
05:31:18 <Lemon> :(
05:31:32 <rust_collector> well, I will have a look
05:31:38 <Lemon> I think my 3456a button to switch to back and front terminals is wonky
05:31:43 <rust_collector> I have at least one large-ish one
05:31:49 <rust_collector> ok
05:32:36 <Lemon> it seems pretty well in cal
05:32:48 <Lemon> it came from a lab, I guess they kept it in cal till the end
05:32:57 <Lemon> it agrees well with the fluke
05:33:26 <rust_collector> well, does it have any reason to disagree?
05:33:48 <Lemon> well they could both be out of cal but I doubt it
05:34:00 <Lemon> they agree within 0.05 ohms
05:34:16 <Lemon> on a 2.01K resistor
05:34:26 Join: Guest|52362 ([email protected]) to #EEVblog
05:35:15 <Guest|52362> is it possible to make something like this but for higher current like 1-2A https://modularaddict.com/mmi-usbpower-pcb
05:35:27 <Lemon> hello guest 52362
05:35:27 <EEVBlog> Hello there, Lemon!
05:35:34 <Lemon> how are you doing today ?
05:36:27 <Guest|52362> hi
05:36:53 <Guest|52362> are you a bot
05:37:07 <Lemon> no, a regular human
05:37:26 <rust_collector> haha, no, he is french
05:37:30 <Guest|52362> that's what a bot would say
05:37:32 <Lemon> who likes when people at least say 'hello' before asking stuff :>
05:38:01 <Guest|52362> french can't be bots?
05:38:41 <rust_collector> not french "humans" you know, they are so emotional and stuff
05:38:53 <Lemon> we are too delicate
05:39:08 <rust_collector> more or less that
05:39:18 <Guest|52362> like an analog vco
05:39:43 <Guest|52362> I'm looking for a psu for my eurorack lunchbox
05:39:56 <rust_collector> so, you want to make +/- 12v from an usb charger?
05:40:04 <Guest|52362> it's been hard to find something I like
05:40:35 <Lemon> I'd use a regular buck/boost circuit to the desired output
05:40:36 <Guest|52362> well, i want Dc input so it can be powered from a brick or powerbank
05:40:53 <rust_collector> but 5v in...
05:40:54 <Lemon> then yeah perfect
05:41:06 <Guest|52362> I've got currently some cheap boost converters
05:41:08 <Lemon> search for 5vin buck boost converters
05:41:38 <Guest|52362> I have found cheap boards from china that do +-5/12 V
05:41:47 <Guest|52362> but they are giving me issues with some digital modules
05:41:51 <rust_collector> can they be "noisy"? or ?
05:41:59 <rust_collector> oh, ok, so
05:42:00 <Guest|52362> i think it must be inrush current, these devices drain a lot of power
05:42:34 <rust_collector> but they do not care much about noise?
05:42:55 <Guest|52362> but idk, the psu where cheap, like 10 bux each, commercial euro psu i find are 100+ and the power ratings are so low
05:43:44 <Guest|52362> $150 for a psu that even takes HP front the front panel is not my liking
05:44:32 <Ysjoelfir> Lemon-Bot: I do like it, but its way to expensive! :D Rusty - Because... erm... I don't like berlin and never was to salzgitter.
05:44:36 <Guest|52362> but idk anything about making my own
05:45:18 <Guest|52362> for reference this is one of the psu i got https://www.futurlec.com/Mini_Power_Dual_12V.shtml
05:47:55 <rust_collector> do you give them enough power on the input?
05:48:19 <Guest|52362> yes the laptop brick is 19V 5A
05:48:20 <Ysjoelfir> No, Salzgitter doesn't need power. its self sustaining.
05:48:33 <Guest|52362> the boost converter is this one https://chinese-electronics-products-tested.blogspot.com/p/hiland-multiple-output-power-module.html
05:48:50 <Guest|52362> idk what's the difference, they both seem SMPS
05:49:16 <rust_collector> https://jobsearch.alstom.com/search/?q=&locationsearch=germany
05:49:23 <Lemon> I should build a small controlled oven
05:49:32 <Guest|52362> it's rated 300mA on each rail, so i power weaker modules, use two of the other PSU to power the remainder
05:49:41 <Lemon> for some experiment, like characterizing resistors, Vrefs etc
05:49:55 <Ysjoelfir> rusty - I should move :D
05:50:11 <Guest|52362> but some modules won't even power up, even if plugged alone. I sent one to RMA and it was working fine on their system.
05:50:11 <rust_collector> I know
05:50:31 <Guest|52362> so now I'm hunting for a better PSU solution
05:51:43 <rust_collector> hmm, are laptop bricks isolated?
05:51:56 <Guest|52362> what does that mean
05:53:34 <rust_collector> I was wondering, if you used 2 laptop bricks, one for positive, and one for negative voltage, you should have plenty of power. but I am not sure if they would misbehave in some way, or not. I have a feeling most of them should work, but, I won't say that they do
05:54:53 <Guest|52362> I can tell one example that happened was one synth module was DOA, until suddenly, after days of rearranging power connectors, it started working. that lasted for a few weeks, until it stopped working again. so i sent it for repair. turns out it was 100% working.
05:55:10 <Guest|52362> I have some other modules that never worked, so I don't know if they are ok or not.
05:55:49 <Guest|52362> over this time I have changed bricks, but am unable to diagnose
05:55:57 <Ampera> I'm about to fall the fuck asleep
05:55:58 <Ampera> good god
05:56:14 <rust_collector> I am awake again
05:56:15 <Guest|52362> should I just get a power bank and try powering the system from it
05:56:45 <Guest|52362> battery power should be more stable i guess
05:56:54 <Guest|52362> could that be it
05:57:02 <Guest|52362> is there a way to measure inrush current
05:57:10 <Ampera> It took me I swear like six reinstalls of Windows 10, wondering why the hell dynamic resolution changes weren't working, until I found out that there's virtio guest tools, and spice guest tools
05:57:25 <Ampera> two completely different things, and I need the SPICE tools, which aren't included with the virtio drivers
05:57:43 <Guest|52362> the spice must flow
05:57:58 <Ampera> QEMU/KVM/libvirt are complete brilliance in a lot of ways, but when it comes to graphics they're a complete fucking disaster
05:58:08 <Ampera> now I want curry, Guest|52362
05:58:16 <Ampera> maybe I'll make some curry ramen later
05:58:22 <Guest|52362> just use unix in an alu body
05:58:32 <Guest|52362> and a backlit bitten apple logo
05:59:17 <Ampera> Guest|52362, I do, OpenBSD on an iBook G4
05:59:28 <Ampera> unfortunately it can't run Visual Studio all that well.
06:00:16 <rust_collector> I thought you wanted something with more amps than that thing, I guess a beefy power bank might do that, but... you won't get...+/-12v at more than an amp or so, I would think?
06:00:34 <Lemon> ho you can get even more
06:00:39 <Lemon> 18650 cells are beefy
06:00:47 <Lemon> some can deliver a ton of amps
06:00:52 <Lemon> well, thats relative
06:01:09 <rust_collector> yes, but can you get that power out of a power bank?
06:01:22 <Lemon> I guess if you modify the circuit
06:01:26 <Lemon> its easy to build one
06:01:30 <Lemon> just keep cells/enclosure
06:01:36 <rust_collector> well, then just buy batteries?
06:01:41 <Lemon> lg hg2 for example
06:01:49 <Lemon> 3ah, you can drain 20amps on it
06:01:54 <Lemon> I wouldnt do it for a long time
06:02:12 <rust_collector> how about those ryobi cordless tool batteries?
06:02:23 <Lemon> but if oyu have lets say 3s4p
06:02:33 <Lemon> thats 12v, 12ah
06:02:41 <Lemon> you can draw easily 40 amps continuously
06:03:11 <Lemon> I wouldnt do it all the time
06:03:13 <Lemon> but even 10 amps
06:03:19 <rust_collector> lemon, I know you can get lots of power out of a large pile of batteries, but that is not a exactly a power bank?
06:03:21 <Lemon> thats fairly safe, out of 80 theoritical max
06:03:36 <Lemon> a rgular usb powerbank is exactly that
06:03:44 <Lemon> like, 3 in series, 4 in paralell or more
06:03:57 <Lemon> whatever you need
06:04:02 <Guest|52362> if power banks can power a 4.5A laptop
06:04:06 <Lemon> for example I had a 13s 4p battery for my ebike
06:04:17 <Lemon> man my ebike is drawing 2kw
06:04:19 <Guest|52362> they can power a 1-2A 12V system
06:04:22 <Lemon> it was working fine
06:04:33 <Lemon> as long as you use good cells ofc
06:04:38 <Lemon> I like LG ones
06:04:47 <Guest|52362> I don't want to build my powerbank
06:04:55 <Guest|52362> I'll just get something within spec
06:04:59 <Lemon> why not ? check vruzend kits
06:05:03 <rust_collector> lg is ok. but... I do not think that is the thing here, maybe
06:05:04 <Lemon> you dont even need to solder it
06:05:09 <Lemon> if you arent after 100 amps it works nicely
06:05:21 <Guest|52362> no, just 1-2A is enough
06:05:31 <Lemon> its a nice thing to build, and you'll get more features by doing it yourself to your liking
06:05:42 <Lemon> well for 1-2 amps, any powerbank will do
06:05:47 <Lemon> usb is usually 2amps max
06:06:02 <Guest|52362> it's just that these psu are rated 300m and 14 - 24Vdc, with an output current of up to 1A.
06:06:05 <rust_collector> yes, but guy wants to make noises with his synth. not make weirdo battery packs (maybe)
06:06:13 <Guest|52362> sthe brick supplies 19V 4.5A
06:06:17 <Guest|52362> so idk what's wrong
06:07:18 <Guest|52362> you asked about the brick itself being isolated
06:07:21 <Guest|52362> what does it mean
06:08:16 <Guest|52362> I mean, ultimately I'd prefer to run the system fom the wall at home, rather than having to use a power bank
06:08:20 <rust_collector> Well, say the negative (or positive) on the output is connected to ground, on the input side
06:08:45 <Guest|52362> hmm idk
06:08:54 <rust_collector> if you hook 2 of those in series, you would make a short
06:09:19 <rust_collector> but if they have a non grounded mains cable, I would say it should work?
06:09:40 <Guest|52362> that sounds too confusing for my brain I don't think I'm messing with any of that
06:10:12 <rust_collector> if the mains plug does not have a ground pin or contact thingie, it should be ok
06:10:38 <Guest|52362> I just toke the brick output into the psu in and soldered some wires between all 3 psu so they all get power
06:11:22 <Guest|52362> well the laptop wall plug does have gorund
06:11:25 <Guest|52362> ground
06:11:28 <Guest|52362> the output does not
06:11:58 <rust_collector> right. then I would probably not try that.
06:12:09 <Guest|52362> what is the problem
06:12:30 <Guest|52362> sharing the input
06:12:47 <Guest|52362> then i would need 3 bricks
06:12:56 <Guest|52362> doesn't make sense
06:13:24 <Ysjoelfir> it does make sense.
06:13:34 <rust_collector> well, if it does not make sense, than just stop thinking about it
06:13:49 <Guest|52362> i'm asking
06:14:44 <rust_collector> if you have one laptop brick, which has the ground on the mains side, connected to the negative on the output side...
06:14:58 <rust_collector> and a second one, that is the same...
06:16:47 <rust_collector> then you try my idea, of connecting the negative of one, to the positive of the other... so you ie end up with 3 output wires... and you use the "middle" one as "0v" the negative of the first one as -19.5v, and the positive of the second as +19.5v...
06:17:32 <rust_collector> then you have connected the ground of the positive to the ground of the negative... so ie you short out one of the bricks
06:17:38 <Guest|52362> the psu don't take AC
06:17:42 <Guest|52362> they take DC
06:17:45 <rust_collector> yes
06:18:06 <Guest|52362> what is the problem of having the, in parallel from the same brick
06:18:29 <rust_collector> the grounds may be connected together, thru your bricks
06:18:41 <rust_collector> parallel is fine, series is not
06:19:24 <Guest|52362> yes of course it's in parallel
06:19:43 <rust_collector> uhm, otoh, I have been awake for a bit more than 30 hours, so I will not say anything complicated
06:19:46 <Guest|52362> I don't expect the inputs of the psu so outpuse anything
06:21:26 <Lemon> damn I spent a bit too much this month
06:21:29 <Ysjoelfir> up until now you are right rusty, no worries there
06:21:38 <Lemon> buying multiple 10/20 bucks things is dangerous it seems
06:22:04 <Ysjoelfir> it is. I only got my welder and the watch, lemon.
06:22:22 <Lemon> hehe :>
06:22:33 <Ysjoelfir> but I got a raise this month, so I had the impression that I want to at least enjoy it once before being kicked out there
06:22:35 <Lemon> I bought tons of resistors, thumbwheel switches, boxes, modules.. etc
06:22:41 <Lemon> ofc !
06:22:54 <Lemon> ho and I bought a nice 4 meters gpib cable
06:22:57 <Lemon> an amphenol one
06:23:03 <Lemon> 30 euros delivered
06:23:16 <Ysjoelfir> this months paycheck will be mostly saved.
06:23:20 <Lemon> because of my desk layout, the scope is too far from the gpib interface
06:23:27 <Ysjoelfir> thats not to shabby, GPIB stuff is usually pretty expensive
06:23:40 <Lemon> yeah and 4 meters cable are hard to come by
06:23:50 <Lemon> did you know that you cant exceed a total of 20 meters per interface ?
06:23:57 <Lemon> per controller I mean
06:23:58 <Ysjoelfir> yes
06:24:14 <Lemon> what happens if you do ? it loses data ?
06:24:20 <Lemon> it implodes ?
06:24:23 <Ysjoelfir> I have a great book about GPIB (sadly only in german available IIRC). it teaches basically everything
06:24:30 <Lemon> awww
06:24:32 <Ysjoelfir> heh, no. you may have problems with data loss
06:25:13 <Lemon> you know what, I think from now on I'll avoid getting chinese components like resistors, caps etc
06:25:32 <Lemon> for 18 euros, I bought 2300 resistors, 147 different values, all branded stuff
06:25:41 <Lemon> so its worth looking around I think
06:26:31 <Lemon> I mean for random projects they work
06:26:38 <Lemon> but they got an horrible tempco usually
06:26:42 <Lemon> and tolerance is a bit wonky
06:26:55 <Lemon> the ones I bought are from vishay, yageo, panasonic etc
06:27:09 <Lemon> 1%, 25ppm if im right
06:27:52 <Lemon> I need to find a capacitor kit, ceramic ones
06:28:17 <rust_collector> https://imgur.com/a/1n8e0kI
06:28:39 <Lemon> dem paint skills man
06:28:41 <rust_collector> I am not sure if that explains what I try to say. I am not very artistic
06:28:44 <Lemon> I feel weak
06:29:02 <rust_collector> you should... sniff some garlic
06:29:38 <Ysjoelfir> works for me rusty
06:29:53 <Ysjoelfir> oh, how did your destruction of the audi work out?
06:30:18 <rust_collector> oh, it was a good selfdestructo bust
06:30:26 <Ysjoelfir> :D
06:31:25 <rust_collector> the green squiggles is my version of circuitry, if you were wondering
06:31:34 <rust_collector> oh, and mains plugs
06:33:48 <Ysjoelfir> I got it, its understandable
06:34:54 <Guest|52362> rust_collector: picture looks ok, how is it related to ou discussion
06:35:10 <Guest|52362> I'm not connecting 2 bricks
06:35:24 <rust_collector> that is what I am wondering also, are we even discussing the same thing?
06:35:25 <Guest|52362> I have one brick powering 3 psu in parallel
06:35:40 <Guest|52362> because each psu is lowe current rated
06:35:44 <Guest|52362> low
06:36:58 <rust_collector> yes, that is why I suggested something else, that can supply a lot of current. as an option. So, after that, I did not see a stop to that idea, so I kept going.
06:37:09 <Guest|52362> but some digital modules, even when they are the only load on the system don't work
06:37:09 <rust_collector> Ysjoelfir, I added a pic to the last link
06:37:45 <rust_collector> the digital synth modules?
06:37:55 <Guest|52362> yes, eurorack format
06:37:57 <rust_collector> or power modules
06:38:07 <Guest|52362> eurorack synth modules
06:38:13 <Ysjoelfir> erm, which one?
06:38:24 <rust_collector> the drawing
06:38:35 <rust_collector> https://imgur.com/a/1n8e0kI
06:38:48 <Ysjoelfir> oh there it is. I should have refreshed it before complaining
06:39:04 <rust_collector> so, yes, audis are like onions
06:39:13 <Ysjoelfir> that looks actually pretty ok, the layer under there
06:39:36 <Guest|52362> so these cheap psu i bought from futurlec are rated 1A, no single module draws that much
06:39:47 <Guest|52362> and yet it fails to power up
06:40:06 <Guest|52362> the psu output voltages are correct
06:41:22 <Guest|52362> to clarify, only a few modules give me problems, as in not powering up, even when powered alone
06:42:41 <Guest|52362> the modules requirements are below the psu specs, but only the overall power rating, i don't know more detailed specs like inrush current that happens on power up
06:43:47 <Guest|52362> troubleshooting has been erratic, with successful power up if modules were plugged in after some others had already powered on
06:44:26 <Guest|52362> that was a challenge to distribute load over the 3 PSU so the whole system would work
06:44:52 <Guest|52362> individual modules not working even when powered alone is a different problem
06:45:29 <Guest|52362> i need to get foo | afk
06:45:33 <Guest|52362> food
06:47:31 <rust_collector> hotdogs here
06:47:45 <Ysjoelfir> its the alion space mathashippee!
06:48:29 <Ysjoelfir> you know it, don't you? https://www.youtube.com/watch?v=-nrUv6XF_Mg&t=291s
06:49:16 <rust_collector> no... what?
06:50:12 <Ysjoelfir> watch it.
06:50:22 <Ysjoelfir> but remember to keep a spare brain on hand
06:51:26 <rust_collector> I have to put a hand on my other head?
06:51:40 <Ysjoelfir> yes, please.
06:52:02 <rust_collector> how am I supposed to hit the keyboard with a hand in the way?
06:52:27 <Ampera> rust_collector, full size splitting axe.
06:53:19 <rust_collector> oh, that explains why gamers keep buying piles of keyboards...
06:53:54 <rust_collector> so that is why gaming keyboards have more springy things?
06:55:44 <Ysjoelfir> yes
06:57:32 <rust_collector> what does the rgb leds have to do with anything?
06:57:54 <Ysjoelfir> I have no idea
06:57:58 <Lemon> https://www.ebay.fr/itm/Ceramic-Disc-Capacitors-50V-Range-of-Values-and-Quantites/261467473085?hash=item3ce0ad04bd:m:mm13qM7ODN5KzzYJV84f5VQ shit, someone stole my name
06:58:01 <Ysjoelfir> I disabled all LEDs on my stuff
06:58:18 <rust_collector> good good
06:58:20 <Ysjoelfir> :O filla lawsuit against him, lemon!
06:58:31 <rust_collector> maybe some nice neon tubes would be ok?
06:59:03 <Ysjoelfir> I have a LED strip under my desk and around my screens. thats fine for me :)
07:05:23 <Lemon> https://www.ebay.fr/itm/450-pcs-KIT-THT-CERAMIC-CAPACITORS-NP0-45-VALUES-x-10pcs/184247582452?hash=item2ae602fef4:g:nBwAAOSw2WhdtejA
07:05:30 <Lemon> do you think those are branded or noname chinese ?
07:05:41 <Lemon> he seems to sell only branded stuff but its not in the description on those
07:05:42 <rust_collector> probably
07:05:59 <Ysjoelfir> I would vote for chinesium for that price.
07:06:17 <Lemon> im going to ask him
07:07:04 <Lemon> https://www.ebay.fr/itm/200pcs-PHILIPS-KIT-THT-CERAMIC-CAPACITORS-20-VALUES-x-10pcs/312565449364?hash=item48c65a4294:g:wgUAAOSws1Zcq7C2
07:07:10 <Lemon> he sells some nice ones
07:07:14 <rust_collector> time for a slice of mayonez
07:07:37 <Ysjoelfir> philips :X
07:07:45 <Lemon> why ?
07:07:52 <Ysjoelfir> personal disliking
07:09:33 <rust_collector> no proper hate? go for it, Lemon
07:10:17 <Lemon> he sells some interesting stuff
07:10:58 <rust_collector> good that he has 20 values, and sell 10 pcs
07:11:08 <Lemon> 20 x 10
07:11:29 <Lemon> im tempted to get those 0.1% 10M resistors for the decade box
07:11:38 <Lemon> but damn, 14.5 usd of shipping
07:11:42 <Lemon> for 10 bucks of resistors
07:12:07 <rust_collector> don't you have enough resistors?
07:12:25 <Lemon> I guess I'll just take the best 9 out of the 20 I bought, they are 1% but I might get 9 good ones
07:12:30 <Lemon> yeah screw them
07:12:33 <Lemon> too expensive
07:13:06 <rust_collector> you can always replace them, if you come across something awesome next year
07:13:13 <Lemon> yeah true
07:13:36 <Lemon> the one I planned to use are not shitty either, they are 1% 25ppm if im right
07:13:42 <Lemon> 50ppm in fact
07:13:48 <Lemon> the caddock ones are 0.1% but 80ppm
07:14:02 <Lemon> its not worth it I think
07:14:12 <Lemon> as I bought 20, I might find nice ones
07:15:42 <Lemon> https://www.ebay.fr/itm/Russian-Vacuum-Capacitor-V-25pF-15kV-NEW-BOXED/160711582821?hash=item256b282465:g:k-AAAOSwWTRWycny
07:15:44 <Lemon> it looks funny
07:16:11 <rust_collector> nah, it looks pretty serious, imo
07:22:16 <Lemon> time to sleep
07:22:21 <Lemon> see you tommorow bois

19:04:31 * Ysjoelfir hands lemon hsn993 's router
19:07:51 <Lemon> :o
19:09:16 <Ysjoelfir> https://snipboard.io/kxTBY3.jpg
19:09:30 <Ysjoelfir> "You did greatly enhance this website, google!"
19:12:45 <Lemon> thanks google !
19:12:53 <Lemon> ho I just read about SSG caps
19:13:00 <Lemon> which are mica whatever ultra stable ones
19:13:03 <Lemon> from the ancient times
19:13:20 <Lemon> PIO MBGO are also the same ?
19:13:59 <Ysjoelfir> no idea what MBGO is, but PIO is not the same as mica
19:14:13 <Ysjoelfir> PIO uses paper as the insulating material, mica caps... well, mica
19:14:13 <Lemon> ha yeah paper in oil
19:14:28 <Lemon> I dont think those are as good
19:14:37 <Ysjoelfir> PIO is pretty crappy
19:14:45 <Ysjoelfir> except for audio stuff*
19:14:54 <K> isnt paper+oil 1920 tech?
19:14:56 <Lemon> ofc
19:14:57 <Lemon> xd
19:15:09 <Ysjoelfir> (*if you are an audiophool)
19:15:32 <Ysjoelfir> well, PIO was used quite a while, K. I have russian made PIO caps from mit 60s
19:15:44 <Ysjoelfir> *mid
19:16:05 <Lemon> I really wonder if caps really change sound
19:16:06 <K> proper audiophools should make their own caps, from era-correct newspapers and ego-vegan-bio pumpkin seed oil
19:16:11 <Lemon> or if its another placebo effect
19:16:26 <Lemon> is there some scientific explainaition
19:17:29 <Ysjoelfir> they do change sound, if they are very bad
19:17:39 <Lemon> yes thats what I think
19:17:44 <K> could be that it changes filter harmonics/phases in some way, but i'd guess that any 2 caps are "different"
19:17:52 <Lemon> and I love the 'but you must burn them in first'
19:18:00 <K> burn in stove yea
19:18:23 <Ysjoelfir> and strangely, it CAN often sound "better", like, more bassy and louder, because the leakage currents can influence the working point of eg. a tube
19:18:28 <Lemon> https://www.ebay.fr/itm/Capacitor-mica-SSG-1-350V-50000pF-0-5-USSR-Lot-of-2-pcs/141020793070?hash=item20d57e88ee:g:tHgAAMXQkcZRmafN
19:18:36 <Lemon> those type of caps are supposedly ultra stable
19:18:47 <Lemon> according to some genrad bridge owning peeps
19:18:53 <K> add more nonlinearities to already nonlinear tubes
19:22:20 <Ysjoelfir> exactly. add more of those nice sounding K3 and K5
19:31:20 <Lemon> damn, a dude measured them and they were better than his genrad cap
19:33:06 <Lemon> https://www.eevblog.com/forum/metrology/(ask)-standard-capacitor/25/
19:36:58 <Lemon> sadly I dont have a decent lcr bridge
19:37:03 <Lemon> just a 0.3% chinese one
19:40:00 <hsn993> hi Ysjoelfir how r u .. u've been absent for long time .. sorry for the router thingy
19:45:12 <Ysjoelfir> better than my atlas LCR with its 1.5% :P ok, maybe that old tube thing from the US Navy is better, but... no idea.
19:45:31 <Lemon> well 0.3% is what chinese said
19:45:40 <Lemon> idk if its the truth, I need a good lcr bridge !
19:45:41 <Ysjoelfir> Hi hsn993 :) Yeah, I was a bit.... lets say.... mentally down for some time because of that whole being kicked out of my job thing.
19:45:43 <Lemon> but those are expensive
19:45:49 <Ysjoelfir> indeed they are
19:46:20 <Ysjoelfir> I still want a wayne
19:47:00 <DHess_US> The tolerance is not as important as the temperature coefficient if you trim it.
19:47:49 <Lemon> thats true yeah
19:48:00 <Lemon> I was mostly talking about the accuracy of my lcr meter
19:48:13 <Ysjoelfir> thats why I chose the polystyrol caps I had flying around
19:48:17 <Lemon> what do you think of those SSG caps ? https://www.ebay.fr/itm/350V-0-1-uF-0-05uF-100000pf-50000pF-variat-SILVER-MICA-SSG-2-CAPACITORS/254335269822?var=553873979542
19:48:33 <Lemon> they are supposedly really great, according to some peeps on eevblog
19:48:45 <Lemon> some guys measured them with ESI/GenRad bridges
19:48:47 <DHess_US> If you have a more precise reference capacitor, then you can use an impedance bridge to measure other capacitors.
19:48:58 <DHess_US> Exactly.
19:49:15 <Lemon> do you think those are a great bet ?
19:49:21 <Lemon> as a 'cheap' standard
19:49:35 <Lemon> it seems they dont move a lot with temp/age
19:49:45 <Lemon> but they need to be in a dry place
19:49:50 <Ysjoelfir> mica should be pretty stable
19:50:14 <Ysjoelfir> especially those ones as they seem to be in a metal case, potentially even oil filled?
19:50:21 <DHess_US> I mean if you have a single reference capacitor, then you can build a quick and dirty impedance bridge which only depends on precision resistors to calibrate other capacitors.
19:50:36 <Lemon> hmmm I heard about that yeah
19:50:43 <Lemon> but DHess whatcha think about those ?
19:50:51 <Lemon> are they as great as it can be for that price ?
19:51:13 <DHess_US> And of course nothing prevents using a precision resistor to calibrate a capacitor if you have a voltage or current reference.
19:51:18 <Lemon> Ysjoelfir they seem to be yeah
19:51:41 <Lemon> I have a roadrunner's lm399 board, and soon a 1K 0.005% resistor :>
19:51:45 <Lemon> thats something I guess
19:52:11 <hsn993> <Lemon> ha yeah paper in oil <----------------- so oil for insulation paper for dielectric ?
19:52:22 <Lemon> I guess !
19:52:37 <Ysjoelfir> oil soaked paper for dielectric
19:52:42 <DHess_US> I've only seen oil filled film used for precision applications. The oil filled film units are trimmed using silver mica.
19:53:21 <Ysjoelfir> lemon, we had that puppy, back than at university https://www.ebay.de/itm/164198301172/
19:53:25 <Ysjoelfir> pretty nice unit
19:53:37 <Lemon> damn !
19:53:43 <Lemon> thats no slouch
19:53:49 <hsn993> so can we take a paper from notebook and put olive oil on it and measure the capacitance ?
19:53:53 <hsn993> xD
19:54:09 <Ysjoelfir> if you add two conductors on both sides... yes
19:54:50 <Lemon> im going to buy three of those mica SSG caps
19:56:15 <Lemon> 11600pf, 0.05uf, and 0.1uf
19:56:26 <Lemon> 0.3%/0.5%
19:56:35 <Lemon> 20 euros delivered
19:57:38 <Lemon> theres some better deals out there but shipping kills it
19:58:10 <hsn993> Ysjoelfir so did u find other job ?
19:58:38 <Ysjoelfir> nope, still nothing
19:59:07 <hsn993> heared things are going back to normal even if covid-19 was not solved
19:59:35 <hsn993> so may jobs to reopen ?
20:00:42 <DHess_US> Hmm, in my impedance bridge, the reference capacitor is 0.099880 microfarads +/-0.1%
20:00:56 <Ysjoelfir> yep. I'm sitting in the office again since monday, but that doesn't mean anything for my job as I wasn't kicked out because of covid, but because of "we tried sooooo hard to create an open position for you, but we didn't succeed in 2.5 years, even though there are many projects that need work to be done!"
20:01:12 <DHess_US> It has a lot of 0.05% resistors
20:01:23 <Ysjoelfir> DHess_US, shame on you, using such an unprecise, unstable capacitor in your bridge! :P
20:01:57 <DHess_US> Ysjoelfir, I don't think that includes the several silver mica capacitors used to trim it.
20:02:28 <Ysjoelfir> ;)

20:39:46 <Lemon> hoooo
20:39:50 <Lemon> do you think its a good one ?
20:39:59 <Lemon> I have no idea of its specs
20:40:03 <Lemon> I need a reference cap right ?
20:42:00 <Lemon> also can you tell me roughly what the description says ? its not loading here
20:42:57 <Lemon> I have no idea if this type of lcr bridge is better or not than my xjw01
20:59:11 <Halcyon> Hey Lemon :)
20:59:24 <Lemon> hi bud !
20:59:42 <Halcyon> What's doing?
20:59:43 <Lemon> wats crakin ?
20:59:47 <Lemon> heh :>
20:59:57 <Lemon> well, I've been buying tons of stuff :P
21:00:20 <Lemon> resistors, especially nice wirewounds russian ones, and some old ssg mica caps, also russian
21:00:21 * Ysjoelfir returned from lunch
21:00:31 <Lemon> I also plan to build a 9 decade resistor box, and a 4 channel voltmeter
21:01:12 <Ysjoelfir> the volvo has at least two more years to live :P Just got the call from my mechanic that the safety check was done with just minor complaints by the checkup engineer
21:01:23 <Lemon> it will outlive you !
21:01:27 <Lemon> 2 years ?
21:01:30 <Lemon> I dont believe it :P
21:01:34 <Lemon> its indestructible !
21:03:02 <Ysjoelfir> well, it needs a new.... new.... erm.... what is that thing called
21:03:16 <Ysjoelfir> connection rod thing that pushes the wheels when you steer
21:03:25 <Lemon> ha yeah
21:03:28 <Lemon> I know the french name
21:03:31 <Ysjoelfir> (like a 35€ part that is swapped in 30 minutes)
21:03:38 <Ysjoelfir> I know the german name xD Koppelstange
21:03:39 <Lemon> a 'cardan' :P
21:04:11 <Ysjoelfir> also the rear shocks are nearly toast. but that was to be expected
21:04:21 <Ysjoelfir> they lasted way longer than you would expect for them to last
21:04:37 <Lemon> meh as they age, it becomes more comfy :P
21:04:56 <Ysjoelfir> the car is now 22 years old, as well as the shocks. and those were special ones, called "Nivomat", with automatic, load dependant hardness regulation
21:05:08 <steve30> o/
21:05:08 <Ysjoelfir> usually they died in the first 7 to 10 years
21:05:24 <Ysjoelfir> Hi steve30
21:15:05 <Lemon> hi steve
21:15:10 <Lemon> I kinda want this for fun https://www.ebay.fr/itm/Set-5pcs-22M-100M-1G-10G-1000GOhm-KVM-Russian-military-vacuum-glass-resistor/254180436862?hash=item3b2e55ab7e:g:Z-YAAOSwzO9eGGxP
21:15:42 <Ysjoelfir> uuh, nice. I like stuff that is encapsuled in glass
21:15:44 <Lemon> 1Tohm
21:15:55 <Lemon> 10% tolerance, thats +- 100Gohm xD
21:16:06 <Lemon> thats crazy when you think about it
21:16:46 <Ysjoelfir> naah, close enough
21:17:00 <Lemon> its not that expensive when you think about it
21:17:53 <Lemon> https://www.ebay.fr/itm/1-1000GOhm-Resistance-standard-P4085-M1-a-0-05-de-decade/254483764249?hash=item3b406a1419:g:j1sAAOSwDABeIQyt
21:17:55 <Lemon> woahhhh
21:22:32 <Lemon> ho btw Ysjoelfir, I bought two analog meters (0-5A and 0-300V AC) for the variac !
21:22:43 <Lemon> I got two pannels of wood im going to use to box it :>
21:23:26 <Ysjoelfir> nice! show me when you
21:23:29 <Ysjoelfir> 're working on it
21:23:40 <Lemon> sure !
21:24:08 <Lemon> https://www.ebay.fr/itm/Lab-Slide-Rheostat-Resistor-for-Exploring-Physics-Electricity-10-Ohms-2-Amps/293002806459?_trkparms=ispr%3D1&hash=item44385404bb:g:B6MAAOSwyXtchl4W
21:24:17 <Lemon> question, what would you use it for, for example ?
21:24:27 <Lemon> I know its to reduce the current
21:24:31 <Lemon> but which application
21:25:22 <Lemon> can you use it with a psu to limit current ?
21:25:49 <Ysjoelfir> you could
21:26:51 <Lemon> but do you have an example ?
21:26:56 <Lemon> if you were to use that
21:34:59 <Ysjoelfir> erm... we used it for teaching purposes in metrology lab, to show the dependance of current and resistance
21:35:50 <Ysjoelfir> like I gave the students some rheostats and said them to dial in an arbitrary voltage, wire that thing up to a lightbulb and see how the current and brightness changes when you move the wiper
21:36:16 <Lemon> ha ok but I mean, you'd get no use of that when building something ?
21:39:37 <Ysjoelfir> well, you could use it to load a circuit or a PSU,...
21:40:26 <Lemon> yeah I got an e load for that
21:40:44 <Lemon> ho also you remember that idea, of a resistor decade with bourns adjustable resistors ?
21:42:16 <Lemon> I found some 22 turns one, with screws
21:42:22 <Lemon> I kinda want to try that idea
21:43:48 <Lemon> we could build an ultimate box by replacing all resistors with those, and tweaking them one by one :P
21:43:54 <Lemon> thats a lot of work but well
21:44:04 <Lemon> it willbe quite accurate, and easy to adjust later !
21:44:13 <Ysjoelfir> I remember, yes. :)
21:45:01 <Lemon> but imagine dude
21:45:06 <Lemon> you'd need aton of those
21:45:08 <Lemon> and a lot of time too
21:45:13 <Lemon> but it could be ultra accurate !
21:56:50 <K> heater!
22:01:39 <Lemon> I wonder why no one does that
22:01:43 <Lemon> well ok it takes time
22:01:53 <Lemon> but you could make an ultra accurate decade box for not that much money
22:02:00 <Lemon> with insane tolerances
22:02:20 <Lemon> you'd have to trim each resistor to a precise value, like 1.00000R, etc
22:03:47 <Lemon> my fluke got a nice resolution
22:03:50 <Lemon> and good accuracy too
22:04:02 <Lemon> I'll check but it seems to be well within cal
22:04:50 * Ampera squeezes Lemon, hugs Ysjoelfir, throws a knackwurst at K
22:04:56 <Lemon> aye
22:05:00 <Lemon> waddup amp
22:05:11 <Lemon> do you like my idea ?
22:05:17 <Ampera> sure
22:05:20 <Ampera> whatever it is
22:05:24 <Lemon> awww
22:05:42 <Lemon> it is to replace each resistor in a decade box with 20 turns bourns, and trim it to the exact desired value
22:05:47 <Ampera> unless it's to create some goldbergian contraption to get me to play PB
22:05:58 <Lemon> it would take time but that would end into an insanely accurate box
22:06:04 <Ampera> What is a decade box
22:06:05 <Lemon> heh
22:06:10 <Lemon> a resistor decade box
22:06:18 <Lemon> you know, you have switches and select the value you want
22:06:22 <Ysjoelfir> woah, Knackwursts!
22:06:24 <Lemon> 9 resistors per decade
22:06:28 * Ysjoelfir hugs Ampera back
22:06:40 <Ampera> yeah I wish I had some
22:06:50 <Ampera> all I have are some stupid bratwursts and some italian sausages
22:07:06 <Ampera> I had set my alarm to 6AM because I wanted to make pancakes
22:07:16 <Ampera> then I woke up at 6AM and said, fuck that shit, and went right the fuck back to sleep
22:07:29 <Ampera> but ended up sleeping like 30 minutes of even good sleep, so there was no point to any of it, and my life is stupid
22:07:38 <Ysjoelfir> I would have loved to do that
22:07:51 <Ysjoelfir> like, going to bed after the damn alarm went off
22:08:09 <Lemon> im going for a nap soon
22:08:25 <Ampera> I happen to set multiple alarms at different points in the night because I am perpetually indecisive as to how I want to sleep
22:08:33 <Ampera> sometimes I want to go to bed really early and get up really early
22:08:40 <Lemon> ha I have a technique thats close to that
22:08:47 <Ampera> but then I'll try to do that, and end up spending all night trying to sleep and failing miserably
22:08:59 <Lemon> I put multiple alarms like 5am, 6am, 7am to say wake me up at 7
22:09:06 <Lemon> so when it ring at 5 im like 'cool, 2 hours left'
22:09:47 <Ampera> my alarms were 2am, 3am, 4am, 6am, 7am, 7:30am, 8am
22:10:08 <Ampera> I fell asleep at around 6PM and then woke up at 10PM
22:10:11 <Ampera> and that's when the pain started
22:10:57 <Ampera> These DHL people are pretty fast
22:11:08 <Lemon> for the cost they better be !
22:11:11 <Ampera> they got my laptop from Hong Kong to NYC in under a day
22:11:16 <Ampera> I paid 30$ for the shipping
22:11:24 <Lemon> thats decent
22:11:40 <Lemon> its ultra expensive here, like for a 100g thing you'll easily pay 15 euros for france to france
22:11:54 <Ampera> Shipping within the US is fairly reasonable with USPS
22:12:12 <Lemon> we do have other alternatives too but its still really expensive
22:12:14 <Ampera> UPS and FedEx are stupid expensive, but they're not really intended for normal people
22:12:28 <Ampera> and DHL doesn't do US <-> US shipping
22:12:32 <Ampera> as I recently learned
22:12:37 <Lemon> sending an apple to your neighboor will be minimum 7 euros
22:13:01 <Ampera> Going international is when it gets expensive, at least with USPS
22:13:14 <Lemon> yeah ima bit sad because I found many great things
22:13:19 <Lemon> and shipping kills the deal
22:13:22 <Lemon> and its small things
22:13:32 <Ampera> i nearly bought a glass guitar slide last night
22:13:44 <Lemon> a bottleneck ? :>
22:13:49 <Ampera> aye
22:13:58 <Lemon> I might have one laying around
22:13:58 <Ampera> curious what it's like to use
22:14:03 <Lemon> but where thats the great question
22:14:23 <Lemon> its funny but for me its nothing more than a 10 minutes fun thingie
22:14:49 <Ampera> I have a big room of cool shit behind me, but the real pisser is it needs to be cleaned and desperately
22:15:13 <Lemon> heh aint we all the same
22:15:22 <Lemon> I only keep my desk tidy
22:15:26 <Lemon> well, somewhat tidy
22:15:57 <Ampera> I do not keep my desk tidy
22:16:02 <Ampera> though I should
22:16:05 <Ampera> it would make working easier
22:16:20 <Ampera> but why do today what you can put off shortly before rapture.
22:16:28 <Lemon> exactly
