00:02:49 <rust_collector> TA DAA!
00:03:22 <rust_collector> I wonder if some of the older clocks would run backwards if you flip the battery
00:04:25 <rust_collector> audi guy was here, so now I have paint and stuff. Should be close enough.
00:08:24 <Ysjoelfir> so you are getting along good with it?
00:08:46 <rust_collector> well, sort of. I took yesterday off
00:10:09 <Ysjoelfir> :O
00:10:11 <Ysjoelfir> shame on you
00:10:17 <rust_collector> my plan is to finish welding in the new piece today, and maybe grind and smooth things a little bit. then put sealer along the edges. then I can do the more quiet stuff tomorrow and monday
00:11:08 <Ysjoelfir> that sounds way to reasonable
00:11:42 <rust_collector> otoh, I might get drunk, and put the thing on fire, who knows?
00:11:51 <Ysjoelfir> xD
00:11:54 <Ysjoelfir> thats more like it
00:12:32 <rust_collector> Looking at it, the a4, and probably passat wagon would look pretty good as a pickup
00:14:37 <Ysjoelfir> I think I once saw a passat pickup
00:15:24 <rust_collector> I suppose, if you used a convertible.... that would have enough "frame" to work ok
00:19:31 Quit: Lord_of_nothing ([email protected]) Ping timeout: 121 seconds
00:19:41 <rust_collector> have you figured out to get it set to non-chinese time yet?
00:25:11 <rust_collector> so, I think it is interesting how good the shitty old mig machine has worked for this project. It has been sitting outside all winter, and the wire is all rusty and nice. I wonder if the rusty wire gives it enough traction, so it feeds better than it used to
00:38:17 <hsn> rusty is nice and all wires
00:38:36 <rust_collector> hey hsn
00:38:43 <hsn> hey h r u
00:39:24 <rust_collector> I am still waiting for the coffee to work. but other than that, I am close to perfection... but you know that
00:39:56 <hsn> so i went to the electronics shop today and i picked up small list of components and the price was 55$
00:40:18 <hsn> its 5:40pm hee
00:40:19 <hsn> r
00:40:41 <rust_collector> It would be. it is 4.40 here
00:41:13 <rust_collector> hmm, I thought there was 2 hours difference. oh well
00:41:29 <rust_collector> so, did you get anything interesting?
00:41:32 <hsn> oh btw the components where (2-3 irf44z nmos / 5 - 2n3904 / 5- 1n4148 / and other components that worth really nothing) ..
00:42:24 * T3sl4 hugs hsn
00:43:14 <hsn> it was basically (24v psu) chineese to charge these scotters .. + few transistors + caps + oh and 1 breadboard
00:44:04 <hsn> irfz44n = 2.65$
00:44:23 <hsn> ^ 1 only :)
00:45:11 <hsn> 4$ for 5x 1n4148
00:45:26 <hsn> T3sl4 how r u ..
00:45:45 <T3sl4> good, just had a spicy breakfast
00:45:48 <Ysjoelfir> rusty - yes, it displays danish time now :)
00:45:49 <hsn> package arrived ?
00:45:58 <rust_collector> well, at least you got your stuff without waiting for xxx days
00:46:21 <hsn> no rusty i wanted inductor at end he doesnt have any .. xD
00:47:13 <rust_collector> close enough
00:48:20 <hsn> i've this fellow here but i dont know what its value : https://photos.app.goo.gl/dcLNtcHjtcakHif37
00:48:30 <hsn> from an old circuit
00:48:38 <Ysjoelfir> "installing your data on your smartwatch. This can take up to 5 minutes!" - 7 minutes later: 55%....
00:49:21 <hsn> and also this was the 2x pictures of the day: https://photos.app.goo.gl/83cDVetaBvjiii7x8 ----- https://photos.app.goo.gl/dsbM52e4UQ2CWX5w5
00:49:49 <hsn> ysjoelfir , never trust a lieing watch ..
00:49:55 <T3sl4> those vines look a bit shaggy, but the sunflowers are nice
00:49:57 <rust_collector> what would happen, if the value of that thing was wrong? would something blow up, or would it just not work perfectly? or maybe it just would not work at all?
00:50:06 <T3sl4> the toroid, is the core yellow and white?
00:50:28 <hsn> yellow , which means which core material ?
00:50:46 <T3sl4> yellow all sides?
00:52:18 <hsn> i call it yellow all side
00:52:43 <T3sl4> hm, might still be #26, but might be something else
00:52:57 <hsn> its bright yello not like the google one im looking at now
00:53:16 <hsn> https://photos.app.goo.gl/hcswhJSt7T1M6Tk56 ^
00:53:52 <hsn> #26 core material ?
00:54:17 <hsn> he T106-26 from Micrometals is a size 106 Toroid core manufactured from Micrometal's unique blend 26 material ^ ?
00:54:22 <T3sl4> if it is, look it up on ...hmm lemme see, micrometals changed their website again
00:55:46 <hsn> i should be looking at yellow/yellow : https://snipboard.io/ptzTsb.jpg ?
00:57:33 <T3sl4> https://www.micrometals.com/products/product-finder/?ordering=shapes-a-z&units=in&shape=vw_plweb_t&material=-26&availability=&od_min=&od_max=&al_min=&al_max=&rp_min=&rp_max= i guess should work? match up the dimensions and see if the inductance matches
01:01:58 <hsn> i think its this : https://micrometals-production-datasheets.s3.amazonaws.com/T68-26A-DataSheet.pdf
01:03:10 <T3sl4> i'm sure it's a chinese copy of something or other, so who knows what the color is, but if it's like #26 it should be around that inductance, A_L * turns^2
01:03:29 <T3sl4> so that's some idea for how to test it, make an oscillator or resonator or something and see what freq it runs at
01:05:35 Join: Lord_of_nothing ([email protected]) to #EEVblog
01:05:50 <hsn> well it was from university days i dont think its chineese but could be
01:06:22 <hsn> so i assume its ~240uH
01:06:37 <hsn> it seems like it has around 64 turns
01:07:19 <hsn> as the tuter used to order from RScomponents genuine parts ..
01:07:27 <hsn> but u know .. u never know ..
01:08:02 <T3sl4> shrug, it could be brand name Bourns or Miller or whatever, but still chinese core
01:17:22 <hsn> https://youtu.be/9qOjeURI2lE
01:17:27 <hsn> accent is wild
01:19:26 <T3sl4> wow
01:20:26 <hsn> it has a lot of distortions
01:20:27 <hsn> xD
01:20:53 <coppice> induction hobs generate some serious noise. So much so that touch sensitive ones only sense around zero crossing in the mains
01:21:42 <T3sl4> for such a thick accent, his diction is actually surprisingly clear
01:22:45 <hsn> i really thought he is doing it on purpoooos
01:24:06 <rust_collector> there has been a lot of comments from czech people saying they think so too. I have no idea, but I sort of like it
01:24:39 <coppice> T3sl4: I remember talking to a German whose English was very good, but his pronunciation had the strong zis, zat, zese and zose quality a lot of Germans have. When talking about pronunciation he was able to pronounce this, that, these and those in a very English way, then immediately went back to saying zis. It was very odd to hear
01:24:58 <T3sl4> hah
01:25:50 <hsn> coppice , he was missing with u then xD
01:27:37 <T3sl4> it takes conscious effort, or lots of training, to break the habit of talking in your normal accent
01:30:37 <coppice> T3sl4: Some people move and quickly settle into the local accent. Some people move and their voice never changes. Its an interesting effect that I think deserves more research
01:31:19 <T3sl4> there's the effect of adopting local accent, at least momentarily
01:31:47 <coppice> as an actor like Hugh Laurie seems expert at doing
01:31:58 <T3sl4> i suppose there'd be a range of effects like that
01:32:16 <T3sl4> hugh does a very convincing american yeah
01:35:24 <Lemon> bois,
01:48:50 * Lemon inhale

01:49:33 * Lemon waves two fingers back
01:50:13 <T3sl4> rude!
01:50:20 <T3sl4> or the opposite of rude, depends
01:52:01 <Lemon> it was only a 3 hours nap ok ?
01:52:38 <T3sl4> those are the best kind of naps
01:53:07 <Lemon> im still tired :/ too short !
01:53:19 <T3sl4> aw
02:40:52 <rust_collector> I have to either nap less than 2 hours, or longer than 4.
02:43:42 Quit: Beni ([email protected]) Ping timeout: 121 seconds
02:47:33 <Ysjoelfir> I have to nap less than 20 minutes or longer than 2 hours
02:56:01 <rust_collector> Ok, I have the rocker panel all done on the bottom, and tacked in a few spots on the top. I guess there is no easy way back now
02:57:35 <Ysjoelfir> pics or didnt happen
02:58:09 <rust_collector> you are right, it didn't happen
03:00:20 <rust_collector> I guess, if I do around 80 more spots, I can start cleaning it up.
03:01:00 <rust_collector> I miss my little half inch belt grinder for things like this
03:01:11 <rust_collector> sander, I guess
03:05:28 <Lemon> Ysjoelfir I did read a bit on reactance, but theres something I dont understand ! you can calculate capacitance once you got reactance, but to calculate reactance, you need capacitance no ? :>
03:11:17 <Ysjoelfir> no
03:11:32 <Lemon> I knew it !
03:11:39 <Lemon> I know nothing !
03:11:42 <Ysjoelfir> xD
03:11:58 <Lord_of_nothing> re

03:13:07 <Ysjoelfir> lunch? I'll be having lunch soon :)
03:13:18 <Lord_of_nothing> space x
03:13:37 <Lord_of_nothing> sadly the irc client have no spell checker
03:13:43 <Ampera> I just voted.
03:14:09 <Lord_of_nothing> what is when the stepp in bird poo on the way up to the capsule?!
03:14:18 <Lord_of_nothing> maybe not tought about everything
03:14:52 <Lemon> Ysjoelfir can you give me a rough explaination of the steps needed to measure accurately a cap to use it as a ref, in an impedance bridge to measure other caps ? :>
03:16:50 <Ysjoelfir> how is a resistance defined, lemon?
03:17:32 <Lemon> via current and voltage ? :s
03:19:31 <Lord_of_nothing> can i die from a shock from static electrity?
03:19:41 <Lord_of_nothing> i get a huge shock from time to time
03:20:04 <Lemon> I guess it needs to be quite strong, and you have a weak heart or whatever
03:21:16 <Lord_of_nothing> my arm feel death to me when i get a huge one
03:21:31 <Lemon> are you sure its static ?
03:21:42 <Lord_of_nothing> my damn german shoes are work as power generator
03:21:43 <Lord_of_nothing> yes
03:22:02 <Lord_of_nothing> now i wear safty shoes the dont build up static eletricity
03:44:07 <Lemon> Ysjoelfir teacher, please enlight me !

04:16:25 <Ysjoelfir> Moin Lordi, so weit gut und dir? Der Lemon braucht deine Hilfe bezüglich Widerständen respektive Reaktanzen.
04:18:09 <Lemon> im a bit lost honestly
04:18:20 <Antarez> du mir geben meinen döner
04:18:23 <Lemon> but im quite hyped by the fact that I could measure stuff accurately without buying expensive shit

04:23:45 <MrMobodies> Hello
04:24:01 <Lord_of_nothing> Grüss Gott
04:24:57 <MrMobodies> What would happen if I run screened telephone cable and ground it to earth?
04:25:40 <MrMobodies> in an attempt to screen it against interference.
04:25:52 <MrMobodies> using CW1600 cable
04:27:15 <Ysjoelfir> rust_collector. could you repeat your short summary of the edda?
04:31:32 <MrMobodies> Nevermind I found this article
04:31:33 <MrMobodies> https://www.epanorama.net/documents/groundloop/basics.html
04:32:08 <MrMobodies> just wondering can it cause a ground loop.
04:36:35 <rust_collector> Ysjoelfir, no, i never read the thing
04:37:12 <rust_collector> I just mentioned a couple things that happened back when I was young
04:39:41 <rust_collector> hah! I was just forced to accept a big bowl of... mini-cinnamon roll sort of things by the russian neighbor. "it is what you say kak tradition"
04:40:16 <MrMobodies> they forced you to eat food?
04:41:00 <rust_collector> no, they just forced me to take the bowl of food home
04:41:17 <rust_collector> You should get a russian neighbor, lol
04:41:40 <MrMobodies> I do know someone i this village but she is Ukranian
04:41:55 <rust_collector> yeah, probably not very different there
04:42:02 <MrMobodies> she also lived in Russia remembers when she had to share a telephone line
04:42:44 <MrMobodies> and she said about all sorts of strangers calling her but it was for next door
04:43:03 <MrMobodies> very nice to talk too
04:43:11 <rust_collector> i have this weird interest in russia, but I guess ukraine would be a good start, as it is not so incredibly huge
04:43:12 <MrMobodies> walks the neighbours dog every day.
04:43:32 <MrMobodies> Here is what I wondered about their telephones
04:43:46 <MrMobodies> Why is fire Number 1
04:43:59 <MrMobodies> on the phone dial
04:44:10 <MrMobodies> more fires that crimes or ambulanace call outs
04:44:17 <rust_collector> uhm, it is hard to get wrong, I guess
04:45:39 <rust_collector> well, if there is a fire, you are more likely to get a lot of injuries, I guess... who knows. maybe it was just that it was the first thing they thought of, when they started using phones?
04:48:02 <Lord_of_nothing> fire its 122 so?
04:48:06 <DHess_US> 35 minutes to launch
04:48:15 <Lord_of_nothing> yes and i hope there is a go
04:49:18 <rust_collector> I read it as 35 minutes to lunch, which is good, I guess
04:50:43 <rust_collector> https://imgur.com/a/jfYuOUS
04:52:46 <Lord_of_nothing> 30min remaining
04:53:27 <rust_collector> what kind of trash are they going to send to space this time?
04:55:38 <DHess_US> White astronaut trash.
04:55:41 * Ysjoelfir steals some of rust_collectors plushki
04:56:09 <rust_collector> OI!
04:56:12 <coppice> they look like they are wearing bike leathers
04:57:00 <MrMobodies> according to a video
04:57:06 <rust_collector> i was hoping they would sent the ugly pickup to space or something
04:57:06 <MrMobodies> I saw before christmas
04:57:09 <MrMobodies> 01 Fightfighters
04:57:09 <MrMobodies> 02 Police
04:57:09 <MrMobodies> 03 Ambulance
04:57:13 <Ampera> well I ordered KFC for delivery
04:57:16 <MrMobodies> https://www.eevblog.com/forum/chat/life-in-ussr-87-how-hard-was-for-soviet-people-to-get-a-telephone-line/msg2529696/#msg2529696
04:57:17 <EEVBlog> 42.
04:57:33 <MrMobodies> Kentucky Fried Chicken
04:57:58 <DHess_US> Those are SpaceX has Space Ninjas.
04:58:05 <Lord_of_nothing> from where?
04:58:27 <rust_collector> alabama
04:58:35 <Ampera> Lord_of_nothing, New York
04:58:44 <Ampera> So I ordered 47 dollars worth of food
04:58:52 <Ampera> the delivery charge is 23
04:58:53 <MrMobodies> tower burgers?
04:58:57 <Ampera> last fucking time I'm ordering from them
04:59:40 <MrMobodies> tower burgers I find delicous but have to really work it out
04:59:44 <MrMobodies> or I put the weight on
04:59:49 <rust_collector> I have never tried kfc stuff
05:00:08 <rust_collector> MrMobodies, maybe you are supposed to have a bit more weight?
05:00:10 <coppice> Ampera: what if you'd ordered $70 of food with free delivery?
05:00:24 <MrMobodies> Crispy chicken burger, with has brown, salad, mayonaise
05:00:25 <Ampera> coppice, it'd be the ripoff of the century
05:00:38 <Ampera> as 70 dollars of food with delivery from the local pizza place is 3 large pizzas
05:00:55 <Ampera> all I got was 16 peices of chickens and a load of sides
05:01:04 <Ampera> half of them I don't even want, but have to buy because it's cheaper with than without
05:01:07 <MrMobodies> $70 delivery, most expensive hear dof
05:01:20 <Ampera> Yeah I can afford it because I'm made of money, but
05:01:25 <MrMobodies> Even Pizza Hut had a free delivery on order of abput £10 or £20
05:01:27 <Ampera> I can't afford that forever.
05:01:37 <coppice> Ampera: how about free food with a $70 delivery charge?
05:01:40 <Ampera> Mailman's here
05:01:50 <rust_collector> say hi to mailman from me
05:01:53 <Ampera> coppice, only if they deliver is by air drop
05:02:05 <Ampera> rust_collector, he's behind the front door
05:02:30 <rust_collector> and....
05:02:41 <coppice> Ampera: how about $35 of food with a $35 delivery charge? seems well balanced
05:03:02 <MrMobodies> I like the way you put things... balanaced
05:03:22 <MrMobodies> or it's all free put the money on delivery.,
05:04:03 <MrMobodies> what did you order from KFC?
05:04:22 <rust_collector> 16 pieces of chicken, and a load of sides
05:04:31 <MrMobodies> I think the one locally is still shut but they due to open for drieve in
05:04:43 <Lord_of_nothing> here the mac d. have hunge delivery cost
05:04:48 <Lord_of_nothing> way to much to order
05:05:00 <Lord_of_nothing> its cheaper to get into a taxi and get truth the drive truth
05:05:48 <MrMobodies> When I last had KFC it had lots of sides to my chicken.
05:06:15 <rust_collector> mac d does not deliver up here, so you would have a cab drive thru the drive thru, and go to your place, I guess
05:06:17 <MrMobodies> it wasn't flat the chicken piece was huge in the burger
05:06:28 <Lord_of_nothing> is there some brand for port just like a kfc?
05:06:46 <MrMobodies> red wine port?
05:06:58 <Ampera> coppice, food would be cheap, but the delivery would be insane
05:07:37 <coppice> Ampera: there's no pleasing some people
05:08:03 <MrMobodies> has it always been that expensive or is just a recent thing with the lockdown?
05:08:12 <Ampera> MrMobodies, it's probably cheaper now
05:08:17 <rust_collector> I would have to be paid at least $10 to eat at a place like kfc
05:08:20 <Ampera> but yeah it's always been that expensive for stuff like this
05:09:03 <Ampera> rust_collector, unfortunately Popeyes doesn't deliver leg and thigh boxes, because some fucking idiots decided that mixed chicken was good
05:09:27 <rust_collector> well, buy food, and not chicken?
05:10:04 <Ampera> rust_collector, don't piss off the op
05:10:29 <rust_collector> we will see...
05:13:20 <EEVBlog> New EEVBlog Tweet: 10 minutes to liftoff! https://t.co/aaadEt0r9R
05:15:29 <Lemon> well I gave up
05:15:44 <Lemon> I ordered that lot of ten 0.3% silver mica caps of 10nf
05:15:53 <Lord_of_nothing> 7:00
05:18:03 <Lord_of_nothing> 5:00
05:18:47 <DHess_US> I would plan on using 4 in series-parallel to get a closer value.
05:19:01 <Lemon> I did thought about this yes !!
05:19:21 <Lemon> but I still dont fully understand how to do what you explained me x)
05:19:35 <Lemon> could give me a rough explaination step by step if you dont mind, please ? :>
05:19:40 <DHess_US> Even the oscillator and tuning networks in my impedance bridge are calibrated to 1000 Hz by using mica capacitors in series-parallel.
05:19:53 <Lord_of_nothing> 3:00
05:20:10 <DHess_US> You can't trim a capacitor for lower value in parallel, and you can't raise the value in series.
05:20:40 <Lemon> thats why you make a mix of the two ?
05:20:46 <DHess_US> So you have to either start at a typically lower value and trim up, which you did not do, or use a combination of series-parallel to get a closer value assuming that some are higher and some are lower.
05:21:24 <Lemon> hmmm interesting
05:21:31 <DHess_US> So for parts ordering, I just assume the final result will be 4 capacitors in series-parallel unless I made more specific arrangements.
05:21:52 <DHess_US> I do something similar when ordering power transistors which I will be matching.
05:21:53 <Lemon> but to determine the value of the cap that will serve me as a reference
05:22:00 <Lemon> which you told me earlier
05:22:05 <Lemon> with current, frequency etc
05:22:24 <Lemon> could you explain me how to do it, step by step (roughly) or if you know a paper somewhat easy to read ?
05:22:41 <DHess_US> I was thinking about it some more. I'd use the current reference and time method.
05:22:53 <Lord_of_nothing> go go go!!!!!
05:23:48 <Lemon> so for a current reference
05:23:58 <DHess_US> So I'd make a precision calibrated current source to drive the capacitor in an integrator configuration and measure the time between two voltage levels using precision comparators.
05:24:24 <Lemon> hmmmm
05:24:25 <DHess_US> The bad part about it is that it relies on the precision of several parts including the current and the precision of the voltage levels.
05:24:46 <Lemon> so I need a stable DC source ?
05:25:29 <Lemon> those precision comparator scares me
05:25:30 <DHess_US> Technically the DC reference needs to be stable but not accurate if you are clever.
05:25:47 <Lemon> I could use a linear lab supply ?
05:25:53 <Lemon> I have a few, and one is really stable
05:25:53 <DHess_US> I wouldn't.
05:26:04 <Lemon> a lm399 ref board ?
05:26:09 <DHess_US> I'd make my own low noise reference because it isn't difficult to do.
05:26:34 <DHess_US> It's more about how the reference is connected than the reference itself.
05:26:40 <DHess_US> The reference should have low 1/f noise.
05:27:03 <Lemon> the big concern for this project is the cost
05:27:55 <DHess_US> The precision comparators are calibrated against each other by doing a calibration run with them both set to the identical trip point. Then the difference in time they produce is substracted from the measurement run.
05:28:40 <Lemon> what do you mean by 'a calibration run with them both set to the identical trip point' ? I know limited things about comparators
05:28:42 <DHess_US> So the capacitor is measured twice; once with the comparators set to the same trip point and another with them set to the precision difference in voltage.
05:29:09 <DHess_US> The comparators aren't identical, they have different offsets and timing.
05:29:40 <DHess_US> So do a run with them measuring the same signal and with the same trip points to find the difference in their response.
05:30:15 <Lemon> I need to read more about comparators
05:30:17 <DHess_US> That removes all of their errors in voltage and time with one measurement using the same signal with the same slope at their input.
05:30:20 <Lemon> I barely understand a thing :/
05:30:48 <DHess_US> Of course I'd build a custom comparator using an operational amplifier pre-amplifier followed by a comparator.
05:31:22 <DHess_US> That's pretty common in precision successive approximation ADCs.
05:31:47 <Lemon> so you wouldnt use something like an ad790jn ?
05:31:51 <DHess_US> Which implies again about 40,000 counts of resolution.
05:32:20 <Lemon> on ic parts, I have many things from the 90s era
05:32:23 <Lemon> that were my fathers stuff
05:32:26 <DHess_US> Not by itselfr.
05:32:31 <Lemon> theres probably comparators in there
05:33:08 <Lemon> I do have a spare 18 bit adc on a breakboard
05:33:12 <Lemon> if its of any use
05:33:22 <DHess_US> Also, I'd use a comparator which is stable in its linear range like the LT1016
05:34:13 <Lemon> and as an op amp, what would you use ?
05:34:39 <DHess_US> I'm not sure.
05:35:02 <DHess_US> Maybe LT1037 or OP-37
05:35:15 <DHess_US> Something with low 1/f noise
05:36:53 <DHess_US> Oh, those wouldn't work. LT1027 or OP-27 then.
05:37:58 <Lemon> so lets make a parts list ! first a lt1016, and a lt1027
05:38:09 <DHess_US> Need two of each
05:38:23 <DHess_US> For the integrator a JFET part is needed.
05:38:55 <DHess_US> Or the integration can be done with no operational amplifier if the current source is better.
05:39:55 <Lemon> https://www.ebay.fr/itm/OP27F-OP27FP-Low-Noise-Precision-Operational-Amplifier-Analog-Device-DIP-8/264288508524?hash=item3d88d29a6c:g:IKIAAOSwtE9beaGc
05:40:00 <Lemon> theres many variations it seems
05:40:04 <Lemon> this one would do ?
05:40:17 <DHess_US> I'd be really careful about buying off of Ebay.
05:40:19 <Lemon> lt1027 are really expensive
05:40:43 <DHess_US> These parts are often counterfeited.
05:40:44 <Lemon> yeah I usually buy only from reputable sellers
05:40:58 <Lord_of_nothing> well that people at the nasa are damn annoying
05:41:04 <Lord_of_nothing> the rember me at hitler...
05:41:44 <Lemon> OP27FN
05:43:15 <Lemon> DHess_US so you said something about a JFET, I guess thats the safest wayt o go ? as idk if my current source will be good enough
05:43:23 <Lemon> ha wait
05:43:30 <Lemon> no its needed either way
05:44:00 <DHess_US> Oh, you need more than one JFET. I meant a JFET operational amplifier for the integrator. You need another for the current source.
05:44:14 <Lemon> so two jefts, which one would you recommend ?
05:44:21 <DHess_US> Something like an LT1022 for each.
05:44:33 <Ysjoelfir> so... what about that lunch. was it good? or did it explode?
05:44:48 <DHess_US> They are in the proper orbit and the first stage landed.
05:45:20 <Lemon> any alternatives to the LT1022 ?
05:45:24 <Lemon> so I can see what's avalaible
05:46:39 <Lemon> they seem hard to get
05:46:42 <Lemon> in europe, at least
05:48:25 <DHess_US> LT1055
05:48:41 <Lemon> those would do as opamps ? https://www.ebay.fr/itm/K140UD25B-OP-27B-IC-Microchip-USSR-Lot-of-2-pcs/143136945556?hash=item2153a07594:g:pCQAAOSwvSNcah6H
05:49:31 <DHess_US> AD744
05:49:48 <Lemon> damn, 10 euros a piece for LT1055's
05:50:16 <Lemon> AD744JN are cheaper
05:50:21 <Lemon> they are ok ?
05:50:30 <DHess_US> I'd say those OP27s are fake.
05:50:43 <Lemon> russian ones ?
05:51:19 <DHess_US> Russian ones with the AD logo? Yes.
05:51:26 <Lemon> hmmmm ok
05:51:37 <Lemon> the alternative is two OP27FN for 20 delivered
05:51:40 <Lemon> which is expensive
05:51:47 <Lemon> shipping is killing the deal, everytime
05:51:51 <DHess_US> These aren't cheap parts.
05:52:03 <Lemon> well yeah true
05:52:06 <Lemon> still a decent price ?
05:52:44 <Lemon> 10 delivered for LT1016 x2, 20 euros for OP27FN x2, and 12.5 euros for AD744JN x2
05:52:54 <Lemon> 42,5 euros for all 6 chips
05:53:13 <Lemon> including 20 euros for the goddamn shipping
05:53:54 <Lemon> and I guess I need other things :>
05:54:01 <DHess_US> There may be more modern parts which are cheaper but I would have to do serious work to find them.
05:54:20 <Lemon> yeah well if those work and the price is ok, thats fine
05:54:34 <Lemon> that will still be way cheaper than buying a bigass genrad bridge
05:54:36 <DHess_US> Yea, JFETs for the current source, whatever for the low noise voltage reference, a power supply
05:54:59 <Lemon> ha wait
05:55:03 <DHess_US> I'd just build a low noise +/-15 volt supply from scratch for it.
05:55:10 <Lemon> thats either AD744 or op26 right ?
05:55:18 <Lemon> not both ?
05:55:22 <DHess_US> Which takes two regulators, 2 operational amplifier, and a reference.
05:55:42 <DHess_US> I never said op26
05:55:57 <Lemon> ha shit op 27, right
05:55:57 <DHess_US> LT1022/LT1055/AD744
05:56:13 <Lemon> so either ad744 or op27
05:56:15 <Lemon> as op amps
05:56:19 <Lemon> 2 of one of them
05:56:23 <Lemon> but not 2 of each
05:56:30 <DHess_US> OP627 might be good for all of them but they are very expensive.
05:57:00 <Lord_of_nothing> https://www.youtube.com/watch?v=SH7N_XADTkU
05:57:01 <Lemon> LT1022 are too hard to find
05:57:09 <Lemon> so I found LT1016 as the comparator
05:57:17 <Lemon> AD744JN as the op amp
05:57:23 <Lemon> and I need jfets now, right ?
05:57:40 <DHess_US> Honestly if you are not somewhat familiar with these parts, I think this project is beyond you.
05:57:42 <Lemon> im a bit lost with models
05:57:57 <Lemon> yes it sounds harder than it was at first
05:57:59 <DHess_US> Get some inexpensive JFET and bipolar operational amplifier and build a cheap version to get it working first.

05:58:38 <Lemon> I think the easiest way would to find someone that can calibrate a few caps for me
05:58:42 <Lemon> then build a simple bridge
05:58:45 <Lemon> to measure other caps
05:58:47 <Lemon> right ?
05:58:54 <DHess_US> sure
05:59:15 <Lemon> Id still get a good accuracy doing so if Iu nderstood it correctly
05:59:30 <Lemon> even if its less convenient than plug and play with a lcr meter
05:59:33 <Lemon> which I dont really care
05:59:44 <Lemon> effort gives good results
06:00:33 <Lemon> https://www.ebay.fr/itm/General-Radio-Genrad-1657-RLC-Digibridge-LCR-Meter/114187653137?hash=item1a961d5011:g:2OYAAOSwNBlelqvH I found this, earlier. But its not really a capacitance bridge as I want
06:00:36 <Lemon> it sounds cheap, btw
06:03:06 <Lemon> so if I understand correctly, what I want to build is an AC bridge circuit, based on the wheatstone bridge
06:03:21 <Lemon> with a standard cap, a standard resistor, a standard variable resistor
06:03:24 <Lemon> and the cap I want to measure
06:03:33 <Lemon> and I use one of my dmms in ac mode as a null meter ?
06:03:44 <Lemon> null detector

06:53:06 * Ampera throws a KFC at Ysjoelfir
06:53:16 <Ysjoelfir> yikes!
06:53:22 <rust_collector> eew!
06:53:26 * Ysjoelfir is fatty and.... chicken-y
06:53:42 * Ysjoelfir hands rust_collector some nice, hot KFC..... things.
06:53:50 <rust_collector> true, but that is not a good reason to throw kfc crap on you
06:54:03 <Ysjoelfir> xD
06:54:36 * Ampera throws a hatchet, missing rust_collector 5cm from his left ear
06:55:03 <rust_collector> arrgh, right in the eye, that is annoying
06:55:30 <Ampera> >missing
06:55:45 <rust_collector> oh. ok. then I wonder what I got in my eye
06:56:38 <rust_collector> at least there is very little chance of it being a hatchet, which is nice
06:59:43 <rust_collector> I am thinking I might want one of those hair cutting things big clive has.
06:59:59 <rust_collector> he says it works like a fleshlight with teeth, lol
07:01:29 <Ysjoelfir> I'm not sure I want to have that :D
07:02:08 <rust_collector> I am getting annoyed by my hair. if I had something like that, I might bother cutting it every now and then
07:03:30 <Ysjoelfir> SWMBO forces me to visit the... hair cutter guy from time to time. I am not pleased
07:04:11 <rust_collector> SWMBT has to cut mine, if I do not go to mom and get it done
07:04:28 <rust_collector> usually before christmas, and on the 18th of may
07:05:59 <Ysjoelfir> swmbt?
07:06:25 <rust_collector> she who must be tolerated
07:07:29 <Ysjoelfir> XD
07:07:43 <steve30> I cut my own hair the last few times
07:08:54 <rust_collector> I am thinking about just swooshing it all off. not that there is much left
07:21:48 <rust_collector> hmm, the usb cut out again.
07:24:59 <DHess_US> Same here steve30. I've just been using a set of clippers for a couple years. I use them for shaving in winter.
07:25:40 <DHess_US> I figure the clippers payed for themselves after two years.
07:25:57 <Lemon> I dont cut my hair
07:26:01 <Lemon> even simplier !
07:29:24 <rust_collector> yaay! ps2 mouse, with a ball and all
07:31:24 <Lemon> I wonder if air variable capacitors found in old radios got a better tempco than silver mica ones
07:31:42 <Lemon> because it seems that high end standard caps from genrad are air variable caps

09:09:00 <rust_collector> hey
09:09:07 <Nothing\> heya rust_collector
09:09:16 <Nothing\> how do you do?
09:09:24 <rust_collector> well, you know
09:09:29 <rust_collector> awesome, as usual
09:09:45 <Nothing\> i'm really glad to hear that :D
09:09:52 <rust_collector> listening to big clive
09:10:11 <Nothing\> listening? has he got a podcast? or you just listening to a video?
09:10:34 <rust_collector> it is a live stream, so a video, but it is not much to look at
09:10:57 <Nothing\> ah, i gotcha
09:11:13 <Nothing\> heh i found a list of programming based games on wikipedia so i went on a spree downloading as many as i could. which i think is like 10-15 plus the 5 additional ones i already have
09:11:52 <Nothing\> some of them are pretty neat, i even found one that runs in a web browser. though you need to register an account. which i hate doing. but it was totally worth it.
09:12:24 <Nothing\> think i'm overwhelming myself though cuz that's like 10 different languages to learn though they have a lot of similarities being based on assembly
09:12:36 <Nothing\> others are more logos type programming, you know like turtle programming
09:12:50 <Nothing\> at least the ones i've played so far
09:14:16 <Nothing\> lol my cat found a new favourite toy. peanuts
09:14:25 <Nothing\> he loves batting them around the room
09:14:27 <rust_collector> I re-cabled an air pump for the neighbor, and got a big bowl of cinnamon roll-bun-things
09:14:34 <Nothing\> he's also taken a liking to paper towel rolls
09:14:40 <Nothing\> ooh nice
09:14:44 <Nothing\> icing on them?
09:14:55 <Nothing\> cuz that's what makes or breaks a good cinnamon bun
09:15:07 <rust_collector> they have a coating of sugar and fat, lol
09:15:15 <Nothing\> awesome
09:15:30 <rust_collector> I think these are fried slightly
09:15:37 <rust_collector> very good
09:16:14 <rust_collector> there is something about toilet paper center thingies.
09:16:55 <Nothing\> lol when i first moved into my one place, my neighbours were nice enough to clear the snow from my driveway with their snowblower for me. so in return i bought them a box of softbaked cookies from the bakery, since i unno how to cook.
09:17:08 <Nothing\> but instead of being grateful, they just looked at me like i was a weirdo
09:17:31 <rust_collector> oh well, they would find out sooner or later...
09:17:39 <Nothing\> you can make nice variable capacitors out of those cardboard tubes
09:17:59 <Nothing\> they work good for home made AM recievers
09:18:38 <Nothing\> rimstar.org taught me that :)
09:18:40 <rust_collector> I have a thing with curling them up, and stuffing as many as I can into a different one. they make interesting patterns
09:19:05 <Nothing\> how do you mean?
09:19:54 <rust_collector> squash one flat, fold it, and fold it and fold it, as much as you can, and stuff it, and as many as you can into one
09:20:10 <Nothing\> ah okay
09:20:57 <rust_collector> I might slice one of those up, and glue them to something, and maybe pour epoxy or something on them, to make a hipster table
09:21:14 <Nothing\> that'd be cool
09:21:26 <Nothing\> i saw a picture once of a couch made entirely out of phone books
09:21:31 <rust_collector> heh
09:21:59 <Nothing\> i imagine the guy went around his neighbourhood and stole everybody's phone book on new phone book day
09:22:30 <rust_collector> he was probably the guy supposed to deliver them
09:22:38 <Nothing\> lol or that
09:23:13 <Nothing\> ahhh man, my vape shop is finally open so i went over and stocked up yesterday on my juice of choice and new coils. it's so nice not using shitty juice with coils i've been using for over a month anymore
09:23:41 <Nothing\> and yet, within like 30 mins i got used to the flavor and can't taste it as strongly anymore
09:24:05 <Nothing\> still nice to have coils that don't taste like burnt ass though
09:25:25 <rust_collector> we had a guy, that was delivering papers and adverts and stuff, but he had a different job, so he paid this kid to ride around on his bike, and deliver the stuff... Well, kid just rode his bike to this place, and dumped it all in a.. uhm, like a..eeh.. "small valley". he did that for a couple years.
09:26:09 <Nothing\> haha i swear i've seen that on a cartoon before somewhere
09:26:09 <rust_collector> then we had a lot of rain, and the little valley flooded, and there was old papers and stuff floating around everywhere
09:26:20 <Nothing\> lol busted
09:26:37 <Nothing\> you'd think they woulda degraded after all tohse years
09:26:55 <rust_collector> probably, to some degree
09:27:12 <Nothing\> speaking of which, for some reason the paper in this one notebook of mine has all turned yellowish after a couple of years
09:27:47 <rust_collector> so, I did find one of the wifes old vape thingies, and cleaned it up. it is much better than the crap I had
09:27:54 <Nothing\> it wasn't even exposed to light or air or anything, they were just closed
09:28:09 <Nothing\> nice
09:28:14 <rust_collector> hmm, interesting
09:28:36 <Nothing\> for some reason i find if i leave my ecig for a week or two with juice in it, it tastes really terrible
09:28:49 <Nothing\> damn cat just bit the shit out of my hand
09:29:03 <Nothing\> had to give him a time out in the bathroom
09:29:19 <rust_collector> this one has a lot of flow. with an adjustable air bleed. I like it
09:29:27 <Nothing\> when he does that i try to give him a toy to bite instead, but sometimes he just insists on biting me
09:29:40 <Nothing\> nice, i've been wanting to buy a new ecig myself
09:29:43 <rust_collector> hmm, maybe you should tazer the cat, if it misbehaves
09:29:59 <Nothing\> i've just got these cheap aspyre breeze things that have no settings at all
09:30:17 <Nothing\> well, i've got a spray bottle, but it doesn't faze him one bit to get sprayed for some reason
09:30:26 <Nothing\> i can spray him until he's soaked and he won't care
09:30:30 <rust_collector> yeah, I had those. I think I could adjust the voltage on some of them, but that was all
09:30:54 <Nothing\> oddly enough the most effective thing i've found to make him stop doing something is to blow a raspberry really loud and violently
09:31:33 <rust_collector> blow a raspberry....
09:31:51 <Nothing\> yeah you know, make a farting noise with your tongue
09:31:58 <rust_collector> ok
09:32:00 <Nothing\> here's the ecig i use: https://res-5.cloudinary.com/www180smokeca/image/upload/c_lpad,dpr_2.0,f_auto,q_auto/media/catalog/product/a/s/aspire_breeze2_grey_02.jpg
09:32:13 <rust_collector> well, if that works...
09:32:40 <Nothing\> it workswell enough, but for some reason it gets this black gunk all inside the bits of the mouthpiece
09:32:50 <Nothing\> looks like oil or something, i have no clue where it comes from
09:33:09 <rust_collector> https://www.eleafworld.com/istick-pico-kit/
09:33:40 <rust_collector> yes, I get the gunk too, on the old ones.
09:33:44 <Nothing\> i'd like to get a "real" ecig, you know one of those deals with adjustable temp and moddable and what not
09:34:05 <Nothing\> ah, right on
09:34:13 <Nothing\> kinda weird it has changeable batteries on that one
09:35:09 <Nothing\> i guess that's probably standard for most non-shit ecigs
09:35:17 <Nothing\> i think i only paid like $30 for mine
09:35:18 <rust_collector> I have no idea
09:35:41 <rust_collector> I probably paid for this one, even if I did not buy it
09:36:05 <Nothing\> except there was a time where i went trhough about 10 different ecigs cuz i lived in an apartment with hard wood floors. so i'd keep dropping them and of course the damn thing would break
09:36:28 <rust_collector> I tend to break them, in my pocket
09:36:51 <Nothing\> lol the one time i was looking over my balcony, vaping, nodded off and dropped it from 13 floors up
09:36:57 <Nothing\> it shattered on impact
09:38:05 <Nothing\> lol i took it back and jokingly tried to get a refund cuz i just bought it ilke a week ago
09:38:35 <Nothing\> i dunno why people like hardwood floors though, those things are such a liability and a pain in the ass
09:38:37 <rust_collector> I can not get it working... I dunno?
09:39:01 <rust_collector> liability... well.
09:39:06 <Nothing\> i couldn't walk around without slippers cuz they hurt my feet so bad, falls were incredibly painful, dropping anything resulted in its destruction
09:39:33 <Nothing\> heaven forbid i should have fallen out of my bed, which is a good 2 or 2.5 feet up
09:39:34 <rust_collector> I grew up downstairs, so I had concrete floors.
09:39:47 <Nothing\> yeah so you know what i'm talking about
09:40:07 <rust_collector> not really. I guess I have tough feet?
09:40:32 <Nothing\> you were probably younger than i am, too
09:40:46 <Nothing\> i'm in my mid 30s now, so my body's starting to fall apart
09:41:16 <Nothing\> i used to bike everywhere, i got a stationary bike a few weeks ago and can scarcely go 2 miles on it before i feel like i'm dying
09:41:31 <rust_collector> I probably was, as it was a while ago. I am just 41 now, so
09:42:12 <rust_collector> well, that is the thing with non moving bikes. you are not moving, and that is fucking boring
09:42:37 <Nothing\> well, i have it in front of the tv so i can watch stuff or play video games while i do it
09:42:48 <Nothing\> but the physical aspect still gets me
09:43:55 <rust_collector> there is a reason why 98% of those bikes are used to hang clothes on
09:44:12 <Nothing\> probably doesn't help that i spend literally 95% of my day sitting on my ass on the computer
09:44:46 <Nothing\> well i'm determined to use it on a regular basis, i really need it
09:45:03 <Nothing\> even though i haven't touched it in a month
09:45:34 <Nothing\> but i figure if i keep trying, eventually it'll stick
09:46:14 <Nothing\> i've lived with ADD all my life so i've got this persistance thing down pat, even if it does take me weeks or months between tries
09:47:01 <rust_collector> find a time, and do it every day. just 20 minutes. just do it
09:48:01 <Nothing\> yeah taht's basically my strategy once i get past the inconcsistency phase, just grit my teeth and do it, and do it as soon as i think of it, no procrastinating
09:48:22 <rust_collector> just pick a time
09:48:32 <Nothing\> that never seems to work for me
09:48:44 <Nothing\> i just put it off anyways, or i forget
09:48:45 <rust_collector> well, not until you do it, lol
09:49:11 <Nothing\> i just have to do it as soon as i think about it, regardless of what i'm doing
09:49:17 <Nothing\> i just drop what i'm doing and do it
09:49:23 <rust_collector> heh
09:49:32 <rust_collector> well, if that works for you...
09:49:33 <Nothing\> cuz what i'm doing is usually just playing a video game or watching youtube
09:49:45 <Nothing\> so it's not exactly important
09:50:36 <rust_collector> so, hook up your game thing to the bike generator, that should do it
09:50:40 <Nothing\> lol my cat just farted
09:50:47 <rust_collector> puff!
09:51:05 <Nothing\> lol dude, my cousins used to refer to farts as a "puff" when they were little
09:51:11 <Nothing\> i always thought it was really weird
09:51:22 <Nothing\> my cousin also called his penis a "dewey"
09:51:41 <rust_collector> yep, I assume they are not cats, so that is a bit weird
09:51:44 <Nothing\> which made malcolm in the middle funnier for me
09:51:53 <Nothing\> wuzzat? farts?
09:52:43 <rust_collector> your cousins... I am guessing they are not cats. if they are, than it is normal
09:53:01 <Nothing\> oh haha yeah just going on ADDesque tangents with that
09:53:22 <Nothing\> you've probably noticed i jupm around from one unrelated thought to another quite a bit
09:56:39 <rust_collector> ah, horses are fun, too bad they are evil
09:57:24 <rust_collector> in other news, I use a ball mouse now...
09:58:34 <Nothing\> really? why?
09:59:01 <Nothing\> what's the advantage? other than hving to clean out weeks old dead skin and dirt from it once a month
09:59:22 <Nothing\> i remember i used to pull strips of black leathery crap from mine when i cleaned it
09:59:26 <rust_collector> because it was the first ps2 mouse I could find. the usb ports on this machine does shut off now and then
09:59:46 <Nothing\> ah, right on
09:59:57 <Nothing\> you know they have usb to ps/2 adapters
10:00:16 <rust_collector> yes, I do. but I found this mouse before one of those
10:01:30 <rust_collector> I was looking for one, but the mouse appeared first
10:02:43 <Nothing\> ah, heh i can't even remember the last time i used ps/2 without a usb adapter
10:02:52 <Nothing\> probably in the early to mid 00s
10:03:29 <rust_collector> I sort of like it, because... well it works, and it leaves more usb ports for me to use, if they happen to work, lol
10:03:49 <Nothing\> hrm i just shaved my wrist to test this new set of hair clippers i got so i can finally cut my hair and it looks weird now. i feel like i should do the other side for symmetry
10:04:02 <Nothing\> why not use a usb hub?
10:04:19 <rust_collector> because... that still uses usb?
10:04:23 <Nothing\> i've never used one myself, but they seem they can be useful in a pinch, especially powered ones
10:04:34 <Nothing\> well yeah, but i mean for the extra usb ports
10:04:38 <rust_collector> sure
10:05:15 <rust_collector> but why not use the other connector that is already there, and avoid adding one more thing to the heap of clutter?
10:07:15 <rust_collector> I mean, there is no real advantage to using usb for something simple like a basic mouse or keyboard?
10:12:52 <Nothing\> actually, i dunno about a mouse, but with a usb keyboard you can press more than 3 or 4 keys simultaneously whereas you can't do thta with ps/2
10:13:16 <rust_collector> sure, but I write text.
10:13:49 <rust_collector> I get that it does not work for gaming things, ut...
10:13:50 <Nothing\> wel, sometimes you've gota be able to hammer the keyboard all at once in frustration lol
10:14:02 <Nothing\> yeah
10:14:10 <rust_collector> yes, you you do not have to post all that on bookface
10:14:29 <Nothing\> i have no clue what the advantage is for a mouse though, maybe increased resolution or sample rate
10:14:53 <rust_collector> some gamer things have like 666 buttons.
10:16:49 <rust_collector> i always bring a keyboard and mouse, when I have to fix the kids computer, because his keyboard uses a windows driver, and I can not use it before windows has started....
10:19:03 <rust_collector> I do have a few of his old keyboards, I am thinking about stealing the switches from it, and make a little synth keyboard thing

10:19:33 <Nothing\> that'd be pretty cool for a project
10:20:03 <rust_collector> at least it should be a pretty reliable switch, and they come with nice "buttons"
10:20:25 <rust_collector> if I do not want to make piano style keys
10:20:31 Join: Ysjoelfir ([email protected]) to #EEVblog
10:21:30 <rust_collector> I guess I could just make keys as a sheet with slots, maybe some plastic... slightly flexible
10:22:13 <Nothing\> i've always wanted to make my own peripheral for the NES
10:22:56 <rust_collector> hmm, I never looked inside a nes controller. I have no idea if they are just switches, or some kind of clever stuff?
10:23:22 <Nothing\> cuz all the input devices use is a cd4021 shift register, which i haven't got, but i have tons of 74hc595s which should be the same
10:23:55 <Nothing\> it's just a shift register, then the CPU sends a strobe signal to read the state of the shift register when it wants to know the input
10:24:14 <rust_collector> ok, that sounds doable, I guess
10:24:24 <Nothing\> yeah, it's realy simple
10:24:29 <Nothing\> the snes basically did the same thing
10:24:52 <Nothing\> actually apparently the CPU in the SNES is basically the exact same as a 6502, but in 16 bits
10:25:10 <Nothing\> or at least the variation of the 6502 the nes uses, since it doesn't use an exact 6502
10:25:54 <Nothing\> the 65C816
10:26:12 <Nothing\> which are still being made, amazingly enough
10:28:10 <T3sl4> Nothing\: parallel-load shift register, so HC164 ish
10:28:21 <Nothing\> ah okay
10:28:33 <Nothing\> i knew they weren't exactly the same as a 74hc595
10:28:55 <Nothing\> it's a shame, of all the chips i have, i haven't got any 4021s :/
10:29:23 <T3sl4> and yeah, things the world will never be rid of: viruses, 8051s, and probably other cores like 6502, 65c816, 68k, etc
10:29:31 <Nothing\> i've basically just been collecting whatever 7400/4000 chips i can get my hands on
10:29:37 <rust_collector> well, if you really want to make a thing like that... you can probably buy 3, some day
10:29:48 <Nothing\> viruses for the 8051?
10:29:49 <Nothing\> weird
10:30:06 <rust_collector> eeh, read again
10:30:09 <Nothing\> wouldn't think they'd have enough memory for a virus, barely enough memory for the program iteslf
10:30:09 <T3sl4> i mean (biological) viruses aren't going away on any comparable time scale :P
10:30:16 <Nothing\> oh lol
10:30:31 <Nothing\> oooh okay, i misread what you typed. my bad
10:30:58 <Nothing\> i thought you said we'd never be rid of viruses for the 8051 and 6502
10:31:01 <Nothing\> etc
10:31:38 <T3sl4> two certainties in life: death, taxes, and 8051s
10:31:43 <Nothing\> woo i took 1/3 of a teaspoon of baking soda for my heartburn and keep burping out clouds of co2. it burns my nose just like if i drank a soda
10:32:05 <Nothing\> 8051s are awesome, though i've never actually used a physical one
10:32:18 <rust_collector> have you tried snorting that?
10:32:33 <Nothing\> i have this 8051 simulator for linux i run on my pi called mcu8051. it's so fucking awesome
10:32:44 <Nothing\> and has the best GUI of anything i've ever seen
10:33:23 <Nothing\> has hardware modules like LEDs, switches, 7 segment displays, i think motors, character LCDs etc
10:34:00 <Nothing\> it's about as extensive as the 8086 emulator, emu8086 i have, except the big difference is it's free
10:34:25 <Nothing\> it's too bad i can't find an ide/simulator that's comparable for windows
10:35:02 <Nothing\> rust_collector, lol i probably have snorted baking soda at some point, lord knows what i put up my nose back when i was younger
10:35:32 <Nothing\> although i didn't use cocaine or heroin very many times. or any snortable street drugs for that matter
10:35:57 <Nothing\> it's disgusting/scary the shit they cut that stuff with
10:36:09 <T3sl4> yeah no kidding
10:36:18 <Nothing\> even just watching the process of how cocaine is made is scary/disgusting
10:36:34 <Nothing\> not exactly USP grade drugs
10:36:37 <T3sl4> well, doesn't bother me, it's just a chemical extraction
10:36:55 <Nothing\> yeah it should just be a simple acid/base extraction
10:37:02 <T3sl4> albeit not exactly with consumption or medical grade chemicals
10:37:05 <Nothing\> except they usually use something like gasoline as the solvent
10:37:58 <Nothing\> i've always wanted to do an acid/base extraction on something, not necessarily recreational. just for the sake of the experience
10:38:14 <Nothing\> but i could never find a source of hcl or naoh
10:38:32 <T3sl4> what?
10:38:34 <Nothing\> for some reason the only drain cleaner i can find here iuses bleach
10:38:36 <T3sl4> literally hardware store
10:38:49 <Nothing\> oh i know the usual sources
10:38:57 <Nothing\> and pool supply stores for the hcl
10:39:03 <T3sl4> base drain cleaner can be harder to find, depends; lye is usually around here at least
10:39:08 <Nothing\> i remember my dad used to have muriatic acid for our hot tub
10:39:17 <T3sl4> or for cleaning concrete
10:39:26 <Nothing\> most sources say to use red devil lye, which doesn't exist in canada
10:39:48 <Nothing\> one of these days i'll find what i need
10:40:06 <Nothing\> i'd like to extract essential oils at some point, too
10:40:27 <T3sl4> usually there's a kind that's not just lye, but some other things, usually sodium nitrate and aluminum granules which react forming bubbles that agitate the crud
10:40:45 <Nothing\> ah
10:40:53 <Nothing\> cuz consumers believe if it bubbles, it's more effective
10:40:55 <T3sl4> well, the aluminum can be strained out of solution or left to react, and the other stuff may not be a problem but it depends what you're doing
10:41:08 <Nothing\> same reason soaps and shampoos froth when you use them
10:41:20 <Nothing\> they don't need to froth, but people think if they froth, they work better
10:41:23 <T3sl4> well, it might work. depends if the bubbles get into the actual crud, or just sit on top
10:41:46 <Nothing\> yeah it could probably be filtered out pretty easily
10:42:36 <T3sl4> solvent extractions and steam distillation, not really so easy to do without a little chemistry gear; a distillation kit can be had for not very much at all i think, like under a hundred bucks or something?
10:42:47 <T3sl4> not a good one ofc, but enough to work with
10:49:22 <Nothing\> yeah that's the other thing, disillation aparatii are costly
10:49:33 <Nothing\> but i've seen some made from stuff found at dollar stores
10:49:48 <Nothing\> though i'd be scared they'd break from thermal shock or chemical corrosion
10:49:58 <Nothing\> or otherwise react with the chemicals
10:50:31 <Nothing\> i think it was cody's lab who made a disillation aparatus out of something he got at the dollar store. though his safety practices are questionable at best
10:51:09 <rust_collector> it depends on what you want to do with it
10:51:13 <Nothing\> he made a video once about how he cleans up mercury spills and all he does is sweep them up. meanwhile the mercury's breaking up into dozens of tiny droplets and scattering all over the floor
10:52:20 <rust_collector> stills was one of the main products they made at the local bus factory here...on evenings
10:54:00 <Nothing\> i found this awesome online game where you use assembly to reverse engineer software to open locks for some sort of espionage or something. it's really neat
10:54:02 <Nothing\> https://microcorruption.com/
10:54:25 <Nothing\> i was wary about signing up for an account but it was totally worth it
10:54:43 <T3sl4> there's a few games like that
10:54:53 <Nothing\> yeah i've been downloading tons of them
10:54:57 <Nothing\> i have a few on steam
10:55:18 <Nothing\> ex-punk, tis-100, astra-256, shenzhen i/o
10:55:28 <Nothing\> teehee the kitty's licking my feet
10:55:51 <T3sl4> :3
10:56:07 <Nothing\> wikipedia has a huge list of them, but they're not all based on assembly, some are more like logos with turtle style programming, but i still enjoy those games
10:56:12 <T3sl4> aw, that link doesn't seem susceptible to at least the most trivial sql injection
10:56:22 <T3sl4> about the only hack i know, so *shrug* :P
10:56:26 <Nothing\> https://en.wikipedia.org/wiki/Category:Programming_games
10:56:53 <T3sl4> yeah tis-100 is one i've seen before
10:57:10 <Nothing\> tis-100 is neat, it's really unique as far as the programming goes
10:57:21 <Nothing\> but i only ever made it past the 2nd level
10:57:40 <Nothing\> it's totally worth trying though
10:57:50 <Nothing\> as are the rest i mentioned
10:58:15 <T3sl4> also Hack N' Slash, an RPG written in Lua that tries to expose some of its internal objects in a very limited, gamified way, which works for what it is but is still not limited enough to prevent some interesting exploits
10:58:16 <Nothing\> aww kitty's sitting in my lap. he almost never sits in my lap
10:58:32 <Nothing\> oh, neat
10:59:09 <Nothing\> i've never used lua before, but i'd like to learn it cuz fceux lets you write lua scripts for your NES rom play sessions
10:59:15 <Nothing\> i think for TASBOT stuff
10:59:45 <Nothing\> i think bizhawk letsy ou do the same thing for SNES
10:59:55 <T3sl4> yeah, it's common for TAS tools
11:00:23 <rust_collector> Nothing\, if you have some linux running on something, try awesomewm, it uses lua.
11:00:31 <Nothing\> i took a quick butcher's at the TAS tools in fceux and i don't think i'd have the patience for it
11:00:39 <Nothing\> rust_collector, is it an emu?
11:00:55 <rust_collector> what?
11:01:02 <rust_collector> it is a window manager
11:01:07 <Nothing\> ah
11:01:20 <rust_collector> sort of your desktop.
11:01:25 <Nothing\> right
11:01:45 <rust_collector> but if you want to try some lua stuff,
11:02:19 <Nothing\> ah,right on

19:18:39 <Lemon> but I have many things to build in the coming weeks ! once I receive parts
19:18:42 <Lemon> so that is nice :>
19:18:56 <Lemon> https://www.ebay.fr/itm/232949758466 I bought those yesterday
19:19:00 <Lemon> but I stop now

19:22:52 <Lemon> I spotted this yesterday
19:22:59 <Lemon> if no ones bid, which is unlikely
19:23:00 <Lemon> I bid
19:23:02 <Lemon> fuck it
19:23:11 <Lemon> this is worth like, at least 5 or 10 times more
19:27:18 <Lemon> in fact its just the capacitor module
19:27:28 <Lemon> the thing its in it, is a bonus
19:27:39 <Lemon> but I guess many people will bid at the end
19:27:56 <Halcyon> I have no idea what I'm looking at
19:28:13 <Lemon> its a precision variable capacitor, inside a bridge or whatever it is
19:28:18 <Lemon> im interested by the capacitor itself
19:28:26 <Lemon> its ultra stable, and really, really accurate
19:28:36 <Lemon> those things are top notch
19:28:48 <Lemon> I want one :>
19:29:42 <Lemon> I want to use it to build a capacitance bridge to measure other caps
