00:31:54 <+Ysjoelfir> preevenings!
00:33:08 <Kuschelpony> good day
00:36:23 * Ampera kisses Ysjoelfir
00:36:31 <Ampera> how are you doing Ysjoelbro?
00:37:40 <K> perveevnings
00:37:48 * Ampera gives K a yam
00:37:51 <+Ysjoelfir> I just came back from visiting three potential customers
00:37:53 <K> a yam?
00:38:05 <Ampera> be thankful for your yam or I'll turn you into a chair
00:38:34 <K> looks like a poor attempt to fake a potato
00:38:56 * Ampera sits on K
00:39:30 <T3sl4> pervenings Ysjoelfir
00:39:57 <T3sl4> enjoy: https://phys.org/news/2021-11-fungus-chemicals-male-flies-infected.html

02:55:11 <TheDude> o/
02:56:03 <K> dood
02:56:38 <TheDude> so... uh
02:56:50 <TheDude> I discovered that my problems were not related to software, like at all
02:56:58 <Ampera> were they related to god?
02:57:09 <TheDude> the thing wouldn't play with linux simply because it would not play at all
02:57:21 <TheDude> the USB-GPIB interface does not work
02:57:24 * Ampera plays with TheDude
02:57:29 <TheDude> and it did work 2 years ago when I last used it
02:57:36 <TheDude> so I assumed it must definitely be good now
02:57:39 <TheDude> not so
02:58:05 <TheDude> also I have an agilent clone
02:58:26 <TheDude> not the real deal
02:58:38 <TheDude> and I'm now pondering whether to try my luck with maybe a NI clone
02:58:54 <TheDude> or buy the real deal from agilent and shell out like 700 fucking euros :/
02:59:23 <Ampera> 700 dollars for something that was available standard on a Commodore PET is hilarious
02:59:34 <TheDude> no
02:59:38 <TheDude> 700 euros
02:59:47 <Ampera> yeah as I said, 700 dollars
03:00:05 <Ampera> euros are just europe's version of a dollar
03:00:13 <Ampera> because they have to be different or something
03:00:20 <TheDude> 8 ben franklins
03:00:35 <Ampera> yep, 700 bucks
03:00:59 <TheDude> common core math in action :)
03:01:23 <TheDude> cheap shot? :D
03:01:43 <Ampera> I never went to public school
03:01:46 <Ampera> so idk what you're on about
03:02:03 <Ampera> I didn't really go to a private school either
03:09:29 <Kuschelpony> good day

04:30:26 <Ampera> this is why bars should be illegal
04:30:46 <TheDude> Mars in particular
04:30:55 <Sigyn> No bars allowed on mars
04:30:59 <Sigyn> it shall be a dry planet
04:31:20 <Sigyn> except for the russian colony of course.
04:33:33 <coppice> No bars allowed on mars? That will be the worst cellular network ever

04:41:30 <coppice> That car has worse rear leg room than a sports car
04:43:50 <arch> what is that, a car for ants?
04:45:36 <coppice> Its a Japanese car they build for the Asian market. The Japanese tend to be a bit smaller than Europeans, and you'll find they actually have alternate smaller body shells for many of their models for East Asian markets
04:59:31 <arch> i want a fiat 500
04:59:35 <arch> it's so cute
05:02:43 <coppice> I suppose they are OK if you are very small
05:11:43 <arch> you know what they say about people with small cars? they have big...feet
05:14:45 <coppice> I find sports cars really odd. Most of them are hard for a tall person to use, but tall people seem to be a large part of the demographic who can afford toys like that
05:16:34 <arch> it's not like you can even put a sports car through its paces if you live in a city anyways. good for rich folks out in the countryside though
05:17:24 * arch robs T3sl4's MLCC and polymer capacitor stash
05:18:17 <coppice> rich folk tend to be towards the taller end of the spectrum
05:21:20 <coppice> How come they can't provide a bit more space for the occupants, when they are only trying to seat 2 of them
05:22:09 <TheDude> damn straight
05:22:12 <arch> aerodynamics probably
05:22:36 <TheDude> weight distribution, in reality
05:26:10 <coppice> arch: aerodynamics might explain the severe lack of headroom, but it shouldn't limit the leg room or width. Most sports cars are quite wide, but they waste much of that width

10:34:27 * Ampera hugs electrohead
10:34:33 <Ampera> how are you doing zappybro?
10:35:10 <jaymax> flappybird brothers?
10:36:30 * electrohead flaps away
10:36:33 <electrohead> lol, hey guys
10:36:39 <electrohead> I'm alright, doing the life thing
10:36:41 <electrohead> how are you?
10:36:43 <electrohead> (and stuff)
10:36:47 <jaymax> Sup Terry and Dennis?
10:37:33 <jaymax> Or if not into the TPB thing... Sup McPoyles?
10:37:35 * electrohead installs templeOS on jaymax's computers
10:37:48 <electrohead> that was the first thought when you said Terry, heh
10:37:56 <electrohead> I actually bought a templeOS mug recently

10:41:26 <jaymax> electrohead the Terry and Dennis reference is related to those idiots that worked for Cyrus, down by the Dover grain mill (that latter part isn't known in the show - just local knowledge) from ~Season 3.
10:43:45 <electrohead> ahh, ok

10:49:37 <rust_collector> You can blame my english on a couple from halifax....
10:50:11 <jaymax> Yeah our accent is not some good.
10:51:37 <rust_collector> I think they moved back there, or, to an what is it called... unregulated? area, not too far from there
10:53:30 <jaymax> I'm unfamiliar with "unregulated"
10:53:58 <jaymax> Commune folk, or maybe Menonites?
10:55:11 <rust_collector> it is probably not the correct word. but it has more to do with not needing to build your house to some standard, and such things
10:55:57 <jaymax> East Hants. :^D
10:58:39 <jaymax> My family is one to talk (West Hants pride, BTW) - so the way to dodge code and regulations is do the work off-grid where it's not noticed. But that's not specific to this province, or this country.
10:59:53 <jaymax> The only other exception are areas that fall to federal jurisctiction instead of proivincial, and people living in such arrangements are getting a raw deal anyway.

12:40:45 <arch> that looks a pretty neat layout, if i do say so myself :D

12:56:25 <Nothing\> i'm not in pain, i'm regular, i'm empty, and i'm doing ter-fucking-rific
12:56:33 <Nothing\> !!1
12:56:36 <Ampera> exelfucingtastic
12:56:39 <Nothing\> gotta include the !!1
12:56:41 <DHess_US> arch, SEPIC/
12:56:42 <DHess_US> ?
12:56:49 <arch> DHess_US, close. Cuk
12:56:55 <Nothing\> lol
12:56:56 <arch> 19V in, -18V out
12:57:05 <Nothing\> a cuk converter
12:57:08 <arch> it's for my audio amp, which is rated 50W
12:57:12 <Nothing\> you don't need no electronics for that
12:57:16 <Nothing\> just a good friend and a bar
12:57:20 <DHess_US> Ah, I've never understood how to select the coupling capacitor size for SEPIC or CUK or the other one.
12:57:25 <Nothing\> get it?
12:57:30 <DHess_US> I've seen values all over the place.
12:57:46 <Nothing\> assuming it's being pronounced as cuck rather than suk or sook
12:58:00 <Nothing\> which i always imagined the pronunciation of cuk was somewhere in between the two
12:58:11 <DHess_US> Zeta is the other topology
12:58:24 <arch> i actually have a writeup here, if you are interested. it turned out really neat when i made a SEPIC with a 10uH coupling cap https://elog.moltensolderlabs.com/elog/2
12:58:25 <EEVBot> [Title] - Electronics Logs - MoltenSolderLabs
12:58:39 <DHess_US> 10 uH coupling cap?
12:58:39 <rust_collector> Nothing\ more like chook
12:58:46 <Nothing\> rust_collector, ah okay
12:58:48 <arch> sorry i meant inductor
12:58:50 <arch> not coupling cap lol
12:58:58 <arch> 10uH Wurth coupled inductor
12:59:03 <DHess_US> The inductor I understand, but not the coupling capacitor.
12:59:26 <Nothing\> oh yeah, i'm not sure which type of languages it applies to, but i know in french there's an accent you put under the letter C that looks like a 5 without the top horizontal line
12:59:37 <DHess_US> Other than ripple current requirements, because I have seen SEPIC converters with coupling capacitors of all kinds of sizes.
12:59:38 <Nothing\> and it's to indicate the C is pronounced as an S sound
12:59:53 <arch> ah, from what i understand, we can rate the coupling cap so that even if it has a pretty high ripple, like 10% of VCC, it's fine
13:00:07 <DHess_US> I just haven't looked in the design enough. I've never had a need for it.
13:00:09 <Ampera> it always disturbs me when this channel is OT
13:00:12 <Ampera> er, on topic rather
13:00:22 <Nothing\> but i assume most uses of the letter C in european languages would have it make an S sound rather than K
13:00:32 <rust_collector> Nothing\ he was serbian,
13:00:39 * arch slaps Ampera with a heavily used tentacle bot
13:00:40 <Nothing\> ah
13:00:46 <Nothing\> that makes sense then
13:00:49 <rust_collector> Ć
13:00:53 <Ampera> arch, if you're gonna abuse me, you might as well fuck me
13:00:55 <Nothing\> aye
13:00:56 <Ampera> dicktease
13:01:03 * electrohead dicks Ampera
13:01:07 * arch films
13:01:09 <Nothing\> i was gonna say, eastern european or slavic languages are different
13:01:19 <electrohead> enough of that for the night, my ass is going to bed
13:01:24 <Nothing\> although they still have the C that sounds like an S a la cyrillic
13:01:36 <Ampera> imagine if two people shared an ass
13:01:46 <Nothing\> Ampera, they do
13:01:48 <Nothing\> and have
13:01:49 <arch> there's conjoined twins that do tho
13:01:52 <Nothing\> yup
13:01:54 <Ampera> no, not like conjoined twins
13:01:54 <electrohead> lol
13:01:57 <Ampera> like you'd share a meal
13:02:02 <Ampera> two people eating out of the same ass
13:02:11 <electrohead> before I head back to bed - cheers, https://www.youtube.com/watch?v=J8gND82t6G4
13:02:12 <EEVBot> [Title] - Youtube: Apollo Comms Part 3: Inside the S-Band Transponder
13:02:12 <Nothing\> it's actually really interesting to look up the anatomy of conjoined twins
13:02:20 <arch> i think you need to retake biology. people usually eat using their mounts and not their buttholes
13:02:28 <arch> mouths*
13:02:55 <Nothing\> electrohead, ooh i like me some off the cuff things like that, space related or otherwise
13:03:10 <Nothing\> man i have this really strange feeling right now
13:03:11 <Ampera> arch, any hole's a goal
13:03:17 <Nothing\> i feel like i'm standing in front of a space heater
13:03:23 <Nothing\> but there's no source of heat around me
13:03:29 <electrohead> Nothing\: if you never heard of that channel, well.. you'll love it, now
13:03:32 <electrohead> avionics <3
13:03:44 <Nothing\> is this what it's like to be targeted by a microwave attack?
13:03:47 <Ampera> I just started watching that series from part 1
13:03:49 <Nothing\> lol
13:04:11 <Nothing\> electrohead, i'm sure i will if the rest of the content's similar
13:04:41 <Nothing\> omfg that was a nightmare
13:04:44 <Nothing\> lol
13:06:39 <Nothing\> i had the video open in edge because that's the browser hexchat opens urls in for some reason i can't rectify, but it's sitting there playing an ad showing like, a screen cap video of somebody using the website they're advertising, meanwhile i'm trying to just copy the url, and edge is all SURPRISE POPUP GUESS WHAT? WE HAVE NEW WAYS YOU CAN COPY URLS!!! YAY!!!!
13:07:03 <Nothing\> how can a company make such a terrible product
13:07:32 <Nothing\> well it's not the product
13:07:34 <Nothing\> it's everything
13:07:54 <Nothing\> everything's just gone downhill in terms of... i don't even know how to put it
13:07:56 <Nothing\> culture?
13:07:59 <Nothing\> no
13:08:04 <Nothing\> sensibility?
13:08:29 <Nothing\> i dunno, something that encompasses those two traits, and others i can't articulate
13:08:59 <Nothing\> blah sorry
13:09:12 <Nothing\> i've been depressed lately so i guess i'm prone to bouts of depressive outbursts
13:10:38 <Nothing\> blah
13:12:32 <arch> i hope 0.4mm thick copperclad will suffice. i dont have THICC copperclads of sufficient size
13:19:46 <Nothing\> in a world filled with mirth and magic you lose time in yourself
13:20:00 <Nothing\> how strongly do you agree with this statement?
13:20:12 <Nothing\> 1. Very strongly
13:20:20 <Nothing\> 2. Somewhat strongly
13:20:27 <Nothing\> 3. Indifferent
13:20:40 <Nothing\> 4. Somewhat disagree
13:21:12 <Nothing\> 5. CONTINUITY FRACTURE
13:21:32 <rust_collector> 8. not sure what that means
13:21:54 <Nothing\> good good
13:22:04 * Nothing\ scribbles on a pad
13:22:52 <Nothing\> you know, the first time i heard the word execrable, i thought the person said ex-scribble lol
13:23:43 <Nothing\> i'm like "wtf is ex scribble? Some group against entropy encroaching on our abstract paintings or something?"
13:25:58 <arch> i wonder if i just stuffed a whole lotta 0.1uF 0805 caps, how the coupling cap section would perform
13:26:21 <Nothing\> can never have too many bypass caps
13:26:30 <Nothing\> unless you're that munsen guy
13:26:34 <arch> vs me using 4x 4.7uF 50V rated 1210 caps
13:26:47 <arch> could be a fun experiment
13:27:01 <arch> i think i will do that. stuff 20x 0805 0.1uF caps :D
13:27:08 <Nothing\> i should say so
13:27:11 <Nothing\> go for it
13:27:22 <Nothing\> savor the joy of discovery
13:28:30 <Nothing\> feel your neurons reaching out to one another and shaking hands to make a new synapse as your brain integrates the constant stream of information into your being
13:28:57 <Nothing\> psyche
13:29:02 <Nothing\> not being

13:30:40 <Nothing\> or am i itchy
13:30:47 <Nothing\> google tells me i have cancer
13:32:03 <Nothing\> lol i wonder if anybody's ever actually successfully caught cancer early by using google

20:37:56 <K> yea, like 128k mp3 rip from dirty vinly
20:38:15 <T3sl4> could be
20:41:37 <K> and now im stuck in spotify, great
20:42:12 <T3sl4> well spotted...ify
20:42:50 <jkop> I would like to monitor 10 temp. sensors scattered as far as 50 meters from each other
20:42:50 <jkop> I am currently thinking about this setup: Pi Zero W + Cat5 cable + 10x DS18B20 + Adafruit IO
20:42:50 <jkop> do you think it is a good choice?
20:44:58 <T3sl4> i doubt those are very noise immune
20:45:26 <T3sl4> coax or shielded whatever would likely be better, still i doubt one of those would drive that much line length all that well
20:45:40 <jkop> I read they can do 100m+
20:45:46 <T3sl4> if they're 50m each from a central hub, on separate pins and not chained, maybe
20:45:51 <jkop> and with special driver - 400m
20:45:59 <Halcyon> I need to wee wee
20:46:08 <T3sl4> you need to french yes yes?
20:46:38 <Halcyon> Isn't that oui oui ?
20:46:45 <T3sl4> wii
20:46:45 <jkop> https://www.maximintegrated.com/en/design/technical-documents/tutorials/1/148.html
20:46:45 <K> 50m feels like esp32+wifi jobie to me
20:47:01 <Halcyon> I was more referencing this: https://www.youtube.com/watch?v=qRYWmaWJL-4
20:47:02 <EEVBot> [Title] - Youtube: The IT Crowd - I need to wee
20:48:31 <jkop> I was considering using wireless temp. sensors, but I did not find anything suitable (long range, not very expensive) and also temp. sensors connected over RS485, but those are more expensive and I cannot connect them in start topology
20:49:12 <steve30> i think i'll go to bed
20:49:13 <Halcyon> jkop: LoRa?
20:49:59 <Halcyon> You can get RS485 to LoRaWAN interfaces
20:50:37 <Halcyon> Long range, long battery life, relatively inexpensive
20:50:53 <T3sl4> cheaper than cable?
20:51:07 <Halcyon> Maybe not
20:51:28 <Halcyon> But if you want wireless, you pay for wireless
20:51:44 <T3sl4> and it can be moved around willy nilly
20:51:48 <Halcyon> Indeed

20:51:57 <EEVBot> [Title] - Not Acceptable!
20:52:00 <Halcyon> These are very sexy
20:52:01 * T3sl4 moves around Halcyon's nilly
20:52:25 <Halcyon> :D
20:52:31 <K> why not 10x esp32+wifi + DS18B20 ?
20:52:46 <K> is the environment RF/wifi hostile?
20:53:55 <Halcyon> Those little LHT65's are under AUD$80
20:54:06 <Halcyon> We use 915-923 MHz here
20:54:14 <Halcyon> Your mileage may vary
20:54:20 <jkop> I have looked into lora before, but without spending 50$+, you cannot get anything good
20:54:41 <Halcyon> *shrug* Just a thought
20:54:47 <K> esp32+wifi modules goes for abou 10$ on amazon
20:54:54 <Halcyon> If you want it done properly, expect to pay money
20:55:06 <Halcyon> Especially for an out of the box solution
20:55:22 <jkop> wifi is a no-go, range is too long, some sensors will be in the basement
20:55:43 <K> ah.
20:55:44 <Halcyon> Yeh so even more reason to do with a sensor in the UHF range
20:55:49 <Halcyon> *go
20:56:07 <Halcyon> Or, as T3sl4 said, cable it
20:56:18 <T3sl4> they seem to have signal quality under control there, in that appnote
20:56:20 <Halcyon> Guaranteed performance, more effort to install
20:56:22 <K> i doubt there will be anything cheap and ready-to-go
20:56:47 <T3sl4> no mention of EMI tho
20:57:06 <T3sl4> at least with coax, and shielded boxes with passthru connectors, you can get good signal quality in the presence of noise
20:57:10 <jkop> I was surprised Chinese do not offer any cheap temp sensors that send data over 433/868 Mhz
20:57:11 <T3sl4> with cat5, who knows
20:57:43 <jkop> cat5 can also be shielded
20:58:01 <T3sl4> good luck with that
20:58:17 <Halcyon> You'll pay for a roll of STP but not <$100 for a wireless sensor?
20:58:44 <T3sl4> or for plain old coax
20:58:53 <jkop> well, 10x100$
20:59:03 <jkop> well, 10x100$ > roll of STP
20:59:29 <Halcyon> True
20:59:42 <Halcyon> But there are options and wireless is easily scalable too
20:59:44 <T3sl4> maybe not after installation costs
21:00:02 <T3sl4> but depends if you want to count that
21:00:11 <Halcyon> Exactly
21:02:47 <jkop> it will be used in the abandon house, so I can just leave cable on the floor and don't care much about installation
21:03:13 <jkop> btw, I am not very happy with what I get with Adafruit IO, are there any better free alternatives?
21:05:10 <T3sl4> beats me, i havent used it

21:05:50 <jkop> I want to be able to monitor temp changes remotely
21:05:50 <Halcyon_> Hold on, you're installing sensors in an abandonded house? Can I ask why?
21:06:02 <Halcyon_> Sorry, stupid internet again
21:06:21 <T3sl4> it's not exactly abandoned then is it :P

21:06:49 <jkop> yes you can, winter is coming, I need to keep it heated at the lowest temp possible so that everything does not get frozen
21:07:17 <Halcyon> Sorry, my internet has a fault at the moment so I missed some of that
21:07:25 <Halcyon> If you aren't living there, why does it matter?
21:07:43 <jkop> winter is coming, I need to keep it heated at the lowest temp possible so that everything does not get frozen
21:09:13 <jkop> by "abandon" I meant currently not used
21:09:58 <T3sl4> how about opening all the taps, close the main, and drain water from the system
21:10:09 <T3sl4> not a bad idea anyway, just as a precaution

21:11:40 <Halcyon> Fucking bullshit copper lines
21:12:32 <jkop> yeah, but you can get mold and that would cost a lot to get rid of
21:13:15 <Halcyon> Doesn't mold like heat?
21:13:23 <Halcyon> So freezing would actually be better
21:14:29 <Halcyon> And winter is typically very dry
21:14:44 <Halcyon> At least in Australia it is
21:16:01 <jkop> "It makes sense that people want to save on heating cost, but one of the best mold prevention techniques is keeping your heating on."
21:16:25 <jkop> "If you seriously want to avoid mold in your home then avoid rooms cooling completely."
21:16:27 <K> hm, why not some thermostat thingies?
21:16:34 <Halcyon> Heating here generally implies reverse cycle air conditioning
21:16:40 <Halcyon> Which dries the air even more
21:16:47 <K> thermostat thingie into a realy box or somth
21:17:00 <Halcyon> But the head causes condensation to form on cold surfaces which can promote mold and mildew
21:17:30 <Halcyon> Also, avoiding stale air helps mold issues.
21:17:33 <T3sl4> where are you, geographically
21:17:45 <Halcyon> *heat
21:18:11 <jkop> in my case it is radiators + electrical and gas heater
21:18:49 <jkop> there is a chance that system can fail (it has already happened before) and will stop heating at all
21:19:00 <Halcyon> In a closed house, keeping it cold and using a HEPA filter would probably be more effective?
21:19:09 <jkop> Eastern Europe
21:19:09 <Halcyon> Keep air moving, keep mold spores low
21:19:44 <jkop> Halcyon, that will not work in my case

21:21:23 <EEVBot> [Title] - Sorry! Something went wrong!
21:22:52 <jkop> K, and how can I use it? how will it control temp in different rooms?
21:23:05 <K> do you have a heater for each room?
21:23:15 <jkop> nope, two central heaters
21:24:45 <K> are heaters controlable?

21:24:47 <EEVBot> [Title] - 403 Forbidden
21:26:36 <jkop> central heaters are controllable, but that does not help much
21:28:07 <Halcyon> Leave internal doors open and use fans to circulate air

21:30:39 <jkop> maybe, but I still need to monitor temperature and I still need to know if system has not malfunctioned
21:39:16 <K> ok then i do not get what is the goal of the system you are trying to build there
