01:02:55 <Nothing\> Δ_Δ
01:03:08 <Nothing\> wait, wait
01:03:17 <Nothing\> ^ ^
01:03:19 <Nothing\> Δ_Δ
01:04:04 <rust_collector> didn't Ampera tell you to not post porn here?
01:04:12 <Nothing\> oops
01:04:20 <Nothing\> speaking of porn, you ever see deaf porn?
01:04:22 <Ampera> /ban Nothing\ forever
01:04:26 <Nothing\> holy crap is that a cacophony
01:04:28 <Ampera> well you can't hear it
01:04:34 <Nothing\> oh no, you can
01:04:36 <Nothing\> very much so
01:04:40 <Ampera> not very deaf isn't it then'
01:04:48 <rust_collector> lol
01:04:51 <Nothing\> it sounds like a mentally handicapped person being bludgeoned to death
01:04:56 <Nothing\> and i'm not even being hypobolic lol
01:05:07 <Ampera> oh, I can imagine that, I've heard your voice before
01:05:14 <Nothing\> lol
01:05:17 <Nothing\> touche
01:05:24 <Nothing\> you should hear it now that i'm sick
01:05:33 <Nothing\> it's gone even worse than before
01:06:00 <Nothing\> actually i realized my voice has become more gravely the last decade or so which i'm not a fan of
01:06:09 <coppice> I've seen deaf people get excited about non-sexual things and have to be reminded to tone down the noise for others
01:06:23 <Nothing\> coppice, yeah it's a similar noise to be sure
01:07:12 <Nothing\> i've never actually known anyone deaf. Though from what i hear it's actually a pretty severe handicap in terms of development and mental capacity because it limits their ability to learn properly
01:07:28 <Nothing\> especially before there were efforts made to make things more accessible for deaf people
01:08:26 <coppice> In the UK we have things called ASBOs - anti-social behaviour orders - which get served against people persistently being unreasonable to their neighbours. It seems quite a few of those are for people who keep their neighbours awake with loud sex.
01:08:26 <Nothing\> there was a really interesting interview i remember seeing with a deaf guy where he talked about growing up in an adopted home, his parents never got closed captioning or tried to explain anything when they watched stuff on tv and they never really tried to include him in other conversations and stuff like that and it wound up really hurting his intellectual development
01:08:44 <Nothing\> then he got access to some more i guess deaf-friendly resources and flourished
01:09:21 Join: arch ([email protected]) to #EEVblog
01:09:43 <coppice> Nothing\: if you are adopting its something you choose to do. Why would you adopt a deaf person and not accommodate their needs?
01:10:10 <Nothing\> coppice, so what? you call the cops for a noise complaint and they serve the people with this order that what? asks them if they "wouldn't mind terribly keeping it down a bit as it's quite late and people must work in the morning"?
01:10:31 <Nothing\> coppice, that's a good point actually i didn't even consider that
01:10:43 <Nothing\> or maybe they didn't know he was deaf at the time. Maybe he was an infant or newborn
01:11:08 <Nothing\> i mean it's pretty easy to tell if you're testing for it. Just clap or make a sound and see if they start. But not many people do that to a baby on purpose.
01:11:27 <Nothing\> or maybe deaf babies cry different...
01:11:32 <Nothing\> i wonder how that would work
01:11:33 <Nothing\> huh
01:11:35 <coppice> Its amazing how resistant people are to accepting their own baby is deaf. My mother lost a friend for a while by telling her she should get her toddler's hearing tested. Later, the mother realised my mum was right, and apologised profusely.
01:11:55 <coppice> Nothing\: they can be fined or jailed for disobeying those orders
01:12:08 <Ampera> It's alright to be an asshole in denial, but it's never okay to be incorrect.
01:12:40 <Nothing\> coppice, i had a feeling it was something to that effect but i didn't think jail. Jail would be appropriate I think if they were being especially egregious but if somebody here was put in jail for a noise complaint, i guarantee the news would blow it out of context.
01:12:54 <coppice> Nothing\: Its an order. Not a polite request. They start out with the polite requests before it escalates to an order.
01:13:19 <Nothing\> like all of those videos the BLM movement posts of black people being assaulted by police, where the video doesn't show the black guy assaulting the police or coming at them with a weapon 15 seconds before it started
01:14:29 <Nothing\> coppice, that's a good tactic i think. Easy as it is to poke fun at British... class I guess you'd call it? One of if not the most important job the police have is to de-escalate situations and that's a pretty good way to at least mitigate escalation in the first place
01:14:30 <coppice> Nothing\: you have to be a serious arsehole to actually end up in jail for an ASBO. I think its usually fines.
01:14:44 <Nothing\> coppice, oh you'd be surprised
01:15:10 <rust_collector> see it as an alternative to paying for prostitutes.
01:15:19 <Nothing\> i mean, this is the place where people torch enough woodlands to cover a sizeable portion of their country in smoke just to tell their friends if their baby's going to be a boy or a girl
01:15:54 <Nothing\> rust_collector, you mean an escort?
01:15:55 <Nothing\> lol
01:16:10 <Nothing\> i never got how escorts are legal and actually in the phone book, but prostitutes aren't.
01:16:17 <rust_collector> call it what you want, you get to have sex and pay
01:16:22 <Nothing\> I guess with an escort the sex isn't implied exactly is it?
01:16:27 <Nothing\> or it probably depends on the service
01:16:55 <coppice> Nothing\: bcause the escorts don't actually advertise their full range of services.
01:16:56 <Nothing\> i considered a place like that once. Or at least a massage parlor. But I decided I'd just be happier to have a wank and keep my $50
01:17:10 <Nothing\> coppice, i guess that's it.
01:17:20 <Nothing\> it's more advertised as a dating service
01:17:26 <Nothing\> or "keep you company" service
01:17:41 <Nothing\> which, if that was really what they did imagine how many seniors would use those places
01:17:42 <coppice> "Dine, fuck, and donate to a good cause."
01:17:55 <Nothing\> then again i can't really speak for their key demographics
01:18:01 <Nothing\> i would imagine young males
01:18:07 <Nothing\> 18-25
01:18:20 <Nothing\> oh wait what was the acronym
01:18:35 <Nothing\> i learned a new one today for privileged white people, WEIRD just trying to remember how it goes
01:19:48 <Nothing\> White, Educated, ... ... ... i've gotta look this up but it was from an article that was talking about that study saying how outdoors helps with depression and that and how that and many other studies focused pretty much purely on this group of people and doesn't apply to people in other cultures or social situations
01:21:00 <coppice> My wife likes to have massages. She came home one day after going to a new place in Shenzhen with a friend, and described the strange experience. When we all said that was really a brothel, and they had to actually give them a massage not to break their cover, she was naive enough to still have trouble accepting it.
01:21:55 <Nothing\> haha
01:22:06 <coppice> How they could walk in, have a quick look around, and not realise the place was for them I have no idea.
01:22:12 <Nothing\> just don't tell her how many men had spooged on the towel she used
01:22:44 <Nothing\> i swear they knew what they were doing when they named the journal PNAS
01:22:55 <Nothing\> i mean it's not PNIS but it's close enough
01:23:36 <Nothing\> dammit i can't find this paper about the WEIRD acronym and study bias
01:24:25 <Nothing\> oh yeah i guess the LHC got some new upgrade and just restarted with record breaking energy levels
01:24:51 <Nothing\> 13TeV apparently
01:25:03 <Nothing\> wasn't the original just over 1 or 2 or something like that?
01:25:10 <Nothing\> i can't remember it was so long ago
01:25:37 <Nothing\> plus i know it can accelerate either protons or lead nucleii so that probably depends on what's being accelerated
01:25:43 <Kuschelpony> i predict they fail again to destroy earth and ask for more funds to increase the energy level again
01:26:08 <Nothing\> lol i think they're a long way from destroying earth
01:26:17 <Nothing\> whether by black hole or strangelet or some other phenomenon
01:26:22 <Nothing\> oh wait
01:26:27 <Nothing\> maybe it already happened in 2012
01:26:43 <Nothing\> that's why the world's falling apart. We're in hell.
01:26:57 <Nothing\> how does the saying go...
01:27:17 <Nothing\> "If you're afraid of dying, and you're holdin' on, you'll see devils tearin' your life away. But if you've made your peace, then the devils are really angels, freein' you from the world. It all depends on how you look at it."
01:27:42 Join: Nothing ([email protected]) to #EEVblog
01:27:48 <Nothing> lol damn d/cs
01:27:58 <Nothing> dunno if that quote made it
01:28:01 <Nothing> "If you're afraid of dying, and you're holdin' on, you'll see devils tearin' your life away. But if you've made your peace, then the devils are really angels, freein' you from the world. It all depends on how you look at it."
01:28:06 <rust_collector> are you saying politicians are angels, if you look at it like that?
01:28:16 <Nothing> rust_collector, i suppose so lol
01:28:29 <Nothing> yeah, the stalinists were angels freeing the proles
01:28:34 <Nothing> hey actually
01:28:42 <Nothing> the nazis DID say Work is Freedom
01:28:57 <Nothing> see, it's making sense
01:29:45 <rust_collector> I still think it is interesting that someone managed to steal that sign
01:30:09 <Nothing> i'd turn it into a coffee table
01:30:16 <Nothing> best conversation piece EVER
01:31:20 Quit: Nothing\ ([email protected]) Ping timeout: 121 seconds
01:31:25 <Nothing> lol that reminds me of a story i saw in the news liek 15 years ago where some goth kids exhumed a corpse from the cematary and turned its skull into a bong
01:31:32 Nick: Nothing is now known as Nothing\
01:31:44 <Nothing\> that was a bit longer than 121 seconds
01:32:15 <Nothing\> or maybe the server pings every 121 seconds so it had to wait for the next ping, plus the timeout time
01:34:16 <Nothing\> hey, question about my function gen
01:34:27 <Nothing\> would it handle it fine if i connected both channels in series?
01:34:38 <Nothing\> or would it be better to just use a mixer circuit
01:35:12 <DHess_US> neither
01:35:17 <Nothing\> no?
01:35:29 <Nothing\> so if i wanted to combine 2 sine waves what would you propose?
01:35:34 <DHess_US> I think you mean in parallel, and a mixer multiplies instead of adding.
01:35:35 <Kuschelpony> what exactly do you want to get?
01:35:36 <Nothing\> which is basically what i was thinking
01:35:48 <Nothing\> DHess_US, ahh okay
01:35:57 <Nothing\> Kuschelpony, just the sum of two sines
01:36:07 <DHess_US> You can put them in parallel, but without isolation the signal from one will cause distortion in the other.
01:36:16 <Kuschelpony> then you best use a passive summer, so two resistors
01:36:29 <Nothing\> DHess_US, so would a common mode choke be appropriate for that?
01:36:38 <Kuschelpony> nothing, not really
01:36:42 <DHess_US> One method to provide isolation is to use a summing amplifier, which can be made with an inverting amplifier with two inputs.
01:36:48 <Nothing\> good to know Kuschelpony
01:37:01 <Nothing\> oh yeah i've made summing amps before
01:37:09 <Kuschelpony> then make one more :)
01:37:23 <DHess_US> Another method is to pad both channels and then place them in parallel.
01:37:28 <Nothing\> actually the lm358's datashete has a diagram for one. Has diagrams for tons of basic op amp circuits actually it's a real treasure trove.
01:37:40 <Nothing\> page 1 has a VCO circuit
01:37:47 <DHess_US> That attenuates the outputs, but since there is twice the attenuation between them, it works to also isolate them.
01:38:12 <Nothing\> Kuschelpony, i actually got an idea for a superior temperature sensing system to what a thermostat uses for your home
01:38:54 <Nothing\> it would just use a sensor in each room that goes off to a summing amp, then to a voltage divider to get the average temperature of all of the rooms
01:39:18 <Nothing\> then controls the furnace based on that. Rather than the temperature just in your living room.
01:39:57 <Nothing\> and you could probably just use bluetooth to transmit the data to a cheap mcu
01:40:13 <Nothing\> so you don't have wires running from one room to the next and all about
01:40:23 <Nothing\> or even just use LORA boards or something i dunno
01:40:32 Quit: Kuschelpony ([email protected]) EOF from client
01:40:41 <Nothing\> dammit. Talkin to a ghost this whole time.
01:40:51 <Nothing\> lol story of my life
01:40:52 Join: Kuschelpony ([email protected]) to #EEVblog
01:41:08 <Nothing\> Kuschelpony, how much of that did you get? lol i didn't realize you were d/ced
01:42:48 <Nothing\> oooh this random book i came across on my sdd sounds good
01:42:52 <Kuschelpony> i had a connection loss, what did i miss
01:42:57 <Nothing\> The Behavior of Lower Organisms
01:44:00 <Nothing\> Kuschelpony, i was saying i was actually thinking of designing a new type of thermostat based on a summing amp where it would have a temp sensor in each room that goes off to a summing amp, whose output is divided by a resistive voltage divider to give the average temperature and then use THAT as the control for the furnace instead of the temperature in just the living room.
01:44:18 <Nothing\> use some sort of wireless system like bluetooth or LORA to transmit the data
01:44:24 <Kuschelpony> yes understood
01:44:49 <Kuschelpony> but i worry you end up with some rooms not warm enough on average
01:44:51 <Nothing\> seems like that should give you an average voltage
01:44:59 <Nothing\> yeah
01:45:13 <Kuschelpony> right it gives average voltage
01:45:27 <rust_collector> I prefer to just remove all doors inside, and let the air move around.
01:45:28 <Nothing\> or in the case of my townhouse, the one room isn't well insulated in the ceiling so it's always about 15c in the winter while the rest of the house is more like 25c
01:45:32 <Nothing\> yes i like it warm
01:45:55 <Kuschelpony> ok, im the opposite as i wish my bedroom would have less than 25°C
01:46:07 <Kuschelpony> living under the roof with damaged isolation
01:46:12 <Nothing\> lol i actually keep my room at 80-82f while i sleep which in c is... 27-28c
01:46:14 <Nothing\> lol
01:46:36 <Kuschelpony> ooof thats sauna hot for me
01:46:50 <Nothing\> 25-26c is my awake and doing stuff temperature. But that's probably because I don't wear clothes. I just lounge in my boxers because clothes feel too restrictive
01:46:52 <Kuschelpony> for me <18 is optimal
01:47:03 <Ysjoelfir> I always knew you are crazy... but THAT crazy? 30c at night, omg
01:47:05 <Kuschelpony> oh i also wear not many clothes at home
01:47:11 <Nothing\> haha Ysjoelfir
01:47:29 <Nothing\> weird thing is, every time i check my body temp if it's normal, it's like 36-36.5
01:47:35 <Nothing\> never anywhere near 37
01:47:49 <Nothing\> and my resting heart rate's like 50-55
01:47:53 <Ysjoelfir> I am literally going berserk because of this apartment being constantly 22C no matter what I do
01:47:55 <Nothing\> so i think my metabolism's just really slow
01:48:22 <Nothing\> Ysjoelfir, lol i actually do get hot flashes from my meds so once in a while i'll have to stick my head outside if it's winter, or in front of the a/c
01:48:31 <Nothing\> and thank god for a/c i dunno how i got on without it before
01:48:46 <rust_collector> ac... heh
01:49:04 <Nothing\> actually i was relatively fine. It was just the days when the heat index went up to 40c that no amount of fans would help me. But otherwise as long as i had a fan on me i was comfy
01:49:19 <rust_collector> heat index
01:49:29 <Nothing\> once you hit 40c though, everything feels warm to the touch. I remember even my desk and my cement floor felt warm
01:49:43 <rust_collector> do you know why that is?
01:49:54 <Nothing\> rust_collector, humidex is what they call it here. I dunno it has a different name everywhere. It's the temperature it feels like when you account for humidity
01:50:04 <Nothing\> or going the other way it would be the windchill
01:50:10 <rust_collector> yes, it is stupid.
01:50:27 <rust_collector> the temp is the temp
01:50:33 <Nothing\> it is because that's what everyone always quotes when they talk about summer temperatures, but they won't tell you
01:50:43 <Nothing\> they'll just say "hey it's supposed to be 37 tomorrow"
01:50:56 <Nothing\> then you check the weather and it says 29 but FEELS LIKE 37
01:51:22 <Nothing\> cuz like i said, it's real humid here on account of the great lakes so we always get really hot humid summers
01:51:25 <rust_collector> I can see why you people over there have your issues
01:51:34 <Nothing\> rust_collector, what latitude are you at there?
01:51:39 <Nothing\> 50something?
01:51:42 <rust_collector> 59, IIrc
01:51:47 <Nothing\> that far? wow
01:52:06 <rust_collector> yes, it is pretty far south
01:52:12 <Nothing\> still i bet with the ocean currents your summers are relatively mild
01:52:25 <Nothing\> especially if you compare it with some place landlocked like siberia of a similar latitude
01:52:55 <Nothing\> rust_collector, i realized where we are here in canada is about as far south as the northern border of california
01:52:56 <rust_collector> sure, it is not often we get long periods of more than 25-30
01:53:30 <rust_collector> and by that, I mean 25 to 30, not some made up number
01:53:40 <Nothing\> rust_collector, what city should i look up climate data for to get an idea of what yours' is like?
01:53:46 <Nothing\> ie the nearest large city
01:53:48 <Nothing\> "large"
01:53:55 <Nothing\> i'm just curious
01:54:16 <Nothing\> i know wikipedia has those charts with average climate data for each month when you look up a city. I always like those.
01:54:33 <rust_collector> there is only one "city" in norway.... some large towns..
01:54:53 <rust_collector> you can look up... tønsberg
01:55:11 <Nothing\> that reminds me. The weather netwokr here has a graph where it shows the forecast for the next 2 weeks, which i say is bullshit because i don't think they can predict weather very well more than 5 days ahead. So I wanted to take a screengrab of each graph every day and compare them
01:55:18 <Nothing\> rust_collector, will do, thanks
01:55:37 <Nothing\> rust_collector, heh the only thing that was coming to mind was svalbard but i think that's an island way up north isn't it?
01:55:42 <Nothing\> if it's even part of norway
01:55:50 <rust_collector> could be that you want to read a bit about that town also, it is pretty old
01:55:59 <Nothing\> oh of course
01:56:03 <Nothing\> that's a given
01:56:11 <Nothing\> what the piss
01:56:23 <Nothing\> i just downloaded this thing a week ago and it already wants to update
01:56:25 <Nothing\> leave me alone
01:56:28 <Nothing\> lel
01:56:46 <Nothing\> won't even let me open the update window so i've just gotta close it anyways
01:56:48 <rust_collector> it is an island way up there. and I am not really sure if it is really norwegian as such, but we do control it. it is weird
01:57:28 <Nothing\> rust_collector, just looking at the first picture of it on the wiki article it's a beautiful city
01:57:42 <Nothing\> i love church architecture. As wasteful as it is
01:57:48 <Nothing\> it's still a beauty to admire.
01:58:05 <Nothing\> Ukrainian Orthodox has some nice churches.
01:58:19 <rust_collector> iIrc, there was meetings about who would "own" svalbard, and they agreed that we would control it, but... I am not sure if it is actually norwegian as such
01:58:29 <Nothing\> heh i've actually set foot in the very first cathedral ever built in North America
01:58:47 <rust_collector> oh yes, that one from 1935?
01:58:50 <Nothing\> it was either in or near Santo Domingo in Dominican Republic
01:58:59 <rust_collector> oh, cool
01:59:06 <Nothing\> rust_collector, i'd have to see the year i'm not even sure the name
01:59:37 <Nothing\> 1550
01:59:40 <Nothing\> https://en.wikipedia.org/wiki/Basilica_Cathedral_of_Santa_Mar%C3%ADa_la_Menor
01:59:41 <EEVBot> [Title] - Basilica Cathedral of Santa María la Menor - Wikipedia
01:59:59 <Nothing\> i also toured one of the homes of Christopher Columbus
02:00:09 <Nothing\> but i was 13 at the time so i didn't know any better
02:00:22 <rust_collector> this is my local real church. we have a closer one, but that is like a kindergarden/office building https://no.wikipedia.org/wiki/Borre_kirke
02:00:23 <EEVBot> [Title] - Borre kirke – Wikipedia
02:01:20 <Nothing\> dominican can't be a very big country though. I remember we took a bus from the north side of the island, and this is on the opposite south end and it only took maybe 3 hours to get there
02:01:45 <Nothing\> rust_collector, damn dude even for mundane buildings you guys have beautiful architecture
02:01:56 <Nothing\> what do you call that style
02:02:07 <rust_collector> roman
02:02:10 <Nothing\> that sort of bulgarian looking style
02:02:16 <Nothing\> ah yeah that would make sense
02:02:19 <Nothing\> a lot of sense
02:02:44 <Nothing\> it pretty much prevaded all of europe not just bulgaria, didn't it
02:02:53 <rust_collector> I like it, because the walls are so incredibly thick, and all stone.
02:02:58 <rust_collector> I think it did
02:03:00 <Nothing\> thinking on it, I can see such buildings in Tudor England
02:03:13 <Nothing\> is it stone? huh
02:03:53 <Nothing\> i always thought most things were waddle and daub back then but i guess not the stuff you actually want to stand for more than 1 year
02:04:00 <rust_collector> look at that window....hole https://upload.wikimedia.org/wikipedia/commons/thumb/0/0b/BORRE_KIRKE_medieval_church_Horten_Norway_2021-07-08_Interior_Altertavle_Abel_Schr%C3%B8der_1665_Lysekrone_chandeliers_Prekestol_pulpit_c_1600_Borrekorset_Borre_Cross_Benkerader_pews_Kiste_coffin_etc_IMG_7972.jpg/1280px-thumbnail.jpg

02:04:06 <Nothing\> you know, apparently a lot of castles were made largely of wood
02:04:15 <rust_collector> sure
02:04:26 <Nothing\> one of the big reasons we think of castles as big stone structures is because that's all that survived of them
02:04:39 <Nothing\> and the big ones are the ones that survived the most
02:04:53 <rust_collector> you use what you have. and wood would also be much quicker to buuild, if that was important
02:05:00 <Nothing\> but castles were a relatively common thing. Usually a dwelling for nobility. And didn't have to be large at all.
02:05:09 <Nothing\> there were lots of single room castles that just housed 1 family
02:05:46 <Nothing\> i remember watching a video a while back that explained the different sizes of castles in general and the family and/or workers who lived in what parts of it.
02:06:04 <Nothing\> and most of the castles were just 1 to 4 room single floor abodes
02:06:20 <Nothing\> and even the 4 room ones, 1 room was usually servant's quarters
02:06:59 <Nothing\> servant's quarters, sleeping quarters, cooking and eating, and I dunno... misc?
02:09:37 <Nothing\> ooh actually i had another function gen/signal mixing question
02:09:48 <Kuschelpony> yes please sk
02:09:49 <Nothing\> what would you recommend as the best solution for creating lissajous patterns?
02:09:50 <Kuschelpony> ask
02:09:59 <Kuschelpony> an scope in XY mode
02:10:04 <Nothing\> i know how to set up the function gen, i'm just wondering in terms of an actual circuit to generate them in
02:10:21 <Kuschelpony> oh you conext one channel to scope X and one channel to scope Y
02:10:34 <Nothing\> so i can just connect it right to my scope
02:10:40 <Kuschelpony> YES
02:10:43 <Nothing\> right on
02:10:51 <Nothing\> yeah i guess they are high impedance inputs aren't they
02:11:00 <Kuschelpony> yes, thats perfectly ok
02:11:09 <Nothing\> and i'd imagine likewise of the outputs on the gen
02:11:23 <Kuschelpony> impedance matching gets only neccesary when the cable length gets above something 0,1* wavelenght
02:11:36 <Kuschelpony> the outputs are likely 50 ohms
02:11:48 <Kuschelpony> so into a high impedance input you get about double amplitude
02:12:07 <Nothing\> okay cool just wanted to make sure cuz in circuitmod like, for my previous example of summing two sine waves, you could do it just by connecting two AC sources in series and the current would give the appropriate waveform.
02:12:29 <Nothing\> Kuschelpony, 75 i think. That's what the cables are.
02:12:50 <Nothing\> but yeah i'm not worried about impedance matching unless i'm doing something with RF
02:12:52 <Kuschelpony> as said, no worries if you stay below somethign 10Mhz
02:13:02 <Nothing\> and i don't think i've gotta use RF frequencies for lissajous patterns lol
02:13:12 <Nothing\> i was just gonna use LF
02:14:23 <Nothing\> Kuschelpony, it's good to have a guy i can bounce ideas off of who knows more than me hehe
02:14:34 <Nothing\> that's why i love this place. Or one of the many reasons.
02:14:56 <Kuschelpony> well, im just an old fart who had tinkered with electronics for about 4 decades
02:15:14 <Nothing\> actually one of the most remarkable things i've noticed about this place is the incredible lack of any and all social drama
02:15:31 <Nothing\> it's such a refreshing change compared to the rest of the internet but I have to wonder at its cause.
02:15:58 <Kuschelpony> uhm... i dont know that "rest of the internet"
02:16:05 <Kuschelpony> so im happy to miss this
02:16:28 <Nothing\> Whether it's because we're all generally more educated. Or because a lot of you are involved more... I guess you'd call it high class things like academia and r&d instead i dunno, drugs and social services.
02:16:33 <Nothing\> i don't know
02:16:41 <Nothing\> Kuschelpony, i'm happy you have. It's a cesspit
02:16:50 <Nothing\> Kuschelpony, like YouTube comments for one.
02:16:56 <Kuschelpony> i think there is a kind of selection going
02:17:00 <Nothing\> or apparently Twitter, though I stay off of there.
02:17:18 <Kuschelpony> IRC, Jabber and classic forums are only appelaing to people who actually care for the Content, as in Text
02:17:40 <Nothing\> reddit i guess used to be bad but nowadays it seems to depend on what subs you go to, much like chats in general there are parts of reddit that have more mature people frequenting them.
02:17:51 <Kuschelpony> people who have intense feelings and emotions are perhaps more inclined to kinds of dynamic interaction with short messages and more bling
02:18:21 <Nothing\> same for YouTube. Channels like EEVBlog or BigClive or channels about physics, opencourseware, lectures, things of that nature tend to have more mature people in the comments.
02:19:20 <Nothing\> Kuschelpony, i don't know about that. I mean we've all seen how talkative i get, but one of my mental health diagnoses is borderline personality disorder, which is apparently characterized by feeling emotions more intensely, among other things
02:19:46 <Nothing\> although i'm kinda skeptical about the diagnosis. I think it's just been brought on by these cursed meds i'm taking.
02:20:02 <Nothing\> so i've been working to get off of them
02:20:12 <Kuschelpony> mmh, i meant more the kind of affective emotions, cant describe that even in my native language right
02:20:37 <Nothing\> they're a damn trap. They work like a miracle for maybe a month or two. Then you end up worse than you were when you started, except now you're addicted to these pills with little hope of getting off of them.
02:20:49 <Nothing\> It's taken me 2 years to cut my dose in half
02:21:04 <Nothing\> my grandmother wound up taking them until the day she died
02:21:30 <Nothing\> and my brother's been on em for about 2 or 3 decades
02:21:47 <Nothing\> Kuschelpony, i see. Yeah translations can be tricky
02:22:02 <Nothing\> which reminds me. I need to write a happy birthday message for my great aunt in germany
02:22:50 <Nothing\> Alles Gute zum Geburtstag! Ich hoffe, Sie haben einen tollen Tag!
02:22:55 <Nothing\> sounds about right i think
02:23:04 <Nothing\> i hate to use a translator but i suck at german
02:23:21 <Nothing\> french is my second strongest language and i can barely cobble together coherent sentences in that
02:23:30 <Nothing\> and that's after 9 years of lessons
02:25:18 <Nothing\> rust_collector, it's interesting looking at the windows of that church you showed me. You can tell just from that that it's gotta be really old because it hasn't got large panes in it. Just a whole bunch of these little like 10^2cm squares of glass
02:25:30 <Kuschelpony> thats too formal, you say "Sie" to a stranger that you greet in a kind of majesty
02:25:54 <Nothing\> ah i didn't know that. What's the less formal form?
02:25:56 <Kuschelpony> i would suggest "Alles Gute zum Geburtstag! Ich hoffe, du hast einen tollen Tag!"
02:26:09 <Nothing\> awesome thanks man.
02:26:11 <Kuschelpony> "du" is the form used for friends and such
02:26:15 <Nothing\> oh yeah du
02:26:24 <Nothing\> i knew that too, just from the stupid ramstein song lol
02:26:26 <Nothing\> du hast
02:26:52 <Nothing\> everyone was singing it here in the late 90's but they'd only sing the first 3 words because that was all they could be bothered to memorize
02:27:36 <Kuschelpony> oops
02:27:52 <Kuschelpony> well to be honest, Rammstein was never anywhere my taste
02:28:25 <Nothing\> same
02:28:34 <Nothing\> but that song was played everywhere here for a brief time
02:28:36 <Kuschelpony> i love the german langauage and vocabulary for all the finesse to have so many words that are so close but any one finetuned for some specific place
02:28:40 <Nothing\> one of THOSE songs
02:28:48 <Kuschelpony> but i dont like the melody for songs
02:28:55 <Nothing\> lol what melody?
02:29:15 <Nothing\> oh you mean in general, i thought you were talking about rammstein
02:29:16 <Kuschelpony> i mean the melody fromed by the words, that does not "flow" well in german language
02:29:16 <Nothing\> lol
02:29:34 <Nothing\> oh, yeah
02:29:43 <Nothing\> that's like that song 99 red balloons
02:29:49 <Kuschelpony> ther is only one german song i somewhat enjoy
02:29:56 <Kuschelpony> ouch not that...
02:30:07 <Nothing\> reading the german version, it's completely different. I dunno how familiar you are with the narrative of it.
02:30:18 <Nothing\> but the English version has a totally different narrative.
02:30:40 <Nothing\> i thought the german version was a lot more beautiful both in terms of the wording and the narrative itself
02:30:56 <Kuschelpony> oh, with music i try to listen to songs that do NO have a narrative in that way
02:31:03 <Nothing\> but having heard the english version all this time i never took the time to sit and listen to/translate the german version
02:31:23 <Nothing\> Kuschelpony, it's hit or miss but this was a good narrative
02:31:25 <Kuschelpony> the one song that is somewhat an exception, or at least tolerable is that 3QuSlRopNR4
02:32:21 <Nothing\> the story being basically a peaceful rally releases 99 red balloons and some military guys see them on radar and mistake it for a nuclear attack and all out war breaks out as a result and at the end of the song there's nothing left
02:32:32 <Nothing\> that's the english version anyways
02:32:34 <Kuschelpony> yes i know that one
02:32:47 <Nothing\> i can't recall the precise details of the german one but you get the idea
02:32:59 <Nothing\> either way to each their own
02:33:03 <Kuschelpony> but i have my brain already overstuffed from everyday life so i just cant deal with interpreting such stuff in addition
02:33:16 <Nothing\> i can understand not wanting a narrative in your songs. It's like me not wanting video games that are heavy on story.
02:33:33 <Nothing\> I always say, "i play video games to play videos games. Not to watch a movie. That's what movies are for"
02:33:37 <Kuschelpony> thats also why i love synthesizer music, or melodic rock
02:33:45 <Nothing\> I imagine the mindset is similar to that?
02:33:53 <Kuschelpony> good qustion i dont know
02:33:58 <Kuschelpony> but likely different for me
02:34:04 <Nothing\> well you kind of hit on a good point there
02:34:18 <Nothing\> thta without a narrative it would leave them free to focus more on the musical aspects
02:34:38 <Nothing\> but at the same time it seems like it's easy to make music that sounds good but doesn't mean anything
02:34:44 <Kuschelpony> i want to listen to music just to get that feeling of flowing with the sound
02:35:03 <Nothing\> just throw together a few chords from pachelbel's canon in D, or play a scale realy fast
02:35:05 <Kuschelpony> hmm in some way this helps to get my brain a bit less overstuffed with thoughts and dealing with social issues
02:35:32 <Nothing\> Kuschelpony, that's true actually. The good sounding but "meaningless" music is good to just get the emotions going. Get yourself pumped up for something.
02:35:36 <Nothing\> eye of the tiger type stuff
02:35:44 <Kuschelpony> think like some summer weather with gentle wind and mild rain that sweeps in patterns over the streets and washes away piled up dirt
02:36:06 <Nothing\> mmm yes naturescapes
02:36:10 <Nothing\> and petrichor
02:36:16 <Nothing\> you know that word? petrichor?
02:36:22 <Nothing\> it's one of my favourites i think
02:36:48 <Nothing\> the smell of wet ground, especially after rain
02:36:59 <Kuschelpony> hmm i dont know that word
02:37:11 <Kuschelpony> but for one of the classics i am currently listening: P_ukfGAd8T4
02:37:13 <Nothing\> heh not many people do. Which is unfortunate.
02:37:15 <Kuschelpony> Space - Magic Fly
02:37:31 <Nothing\> i haven't been able to listen to music really in some years
02:38:09 <Nothing\> part of my mental health issues has me suffer from getting songs stuck in my head for weeks on end and literally every waking moment, at least that i'm aware.
02:38:18 <Kuschelpony> i can only on specific hours, otherwise i need silence
02:38:19 <Nothing\> which becomes very distressing, regardless of the song.
02:38:37 <Nothing\> and then the more distressed or just stressed from other things i get, the worse it gets.
02:38:54 <Nothing\> so what WAS an enjoyable song becomes an instrument of psychological torture.
02:39:19 <Nothing\> i still bite the bullet and listen to music once in a while if i'm in the mood but it's rare these days.
02:39:48 <Nothing\> it's bad enough though that i'll mute the music in video games when i play just so i don't accidentally hear a jingle or melody because that's all it takes.
02:40:09 <Nothing\> even something my mind comes up with, a few notes can be enough.
02:40:26 <Nothing\> i told my shrink and he just laughed it off so, screw him.
02:40:34 <Nothing\> it's not like there's a magic pill that'll make it stop anyways.
02:40:38 <Kuschelpony> did you listen to the two songs (i posted the Youtube ID) ?
02:40:43 <Nothing\> and that's all shrinks do here.
02:40:44 <Kuschelpony> whats your opinion?
02:41:00 <Nothing\> no, sorry. i'm not in a place where i can listen to music atm.
02:41:48 <Nothing\> i'm not the best person to get opinions about music from anyways
02:42:15 <Nothing\> dammit my one cat keeps beating up my other smaller cat
02:42:19 <Kuschelpony> ok just sharing my favorites
02:42:41 <Nothing\> Kuschelpony, sorry man i wish i could help. I know what it's like wanting to share things that bring you joy.
02:43:50 <Kuschelpony> thats also one i really like https://www.furaffinity.net/view/14380034/
02:43:52 <EEVBot> [Title] - - Keepers of the Light - by foxamoore -- Fur Affinity [dot] net
02:44:25 <Kuschelpony> on another side im currently busy traing if i can get a specific type of snorkel mask anywhere in an european shop
02:44:31 <Nothing\> i've never really taken to new music anyways. I dunno if i just didn't listen to the right music or if i'm just an old fart stuck in his ways.
02:44:43 <Nothing\> ever since things went electronic i sorta gravitated away from new stuff.
02:45:04 <Nothing\> i loved aphex twin, but i think that had more to do with the drugs i was taking at the time lol
02:45:58 <Nothing\> oh yeh i forgot the X vs Y on my scope sucks balls for some reason
02:46:07 <Nothing\> it just plots it as a series of dots instead of a steady line
02:46:42 <Nothing\> which there is a setting for that but it doesn't change anything
02:47:14 <Kuschelpony> i am happy to find new music to my taste but the way music is made has fundamentally changed somethign 30 ysears ago
02:47:37 <Nothing\> i'm kicking myself over buying this scope anyways cuz i paid like an extra $100 or $150 for the 200mhz model over the 100mhz model then found out all i had to do was change the firmware in the 100mhz model to unlock the 200mhz mode
02:48:14 <Nothing\> Kuschelpony, heh every so often i'll go back and listen to music i liked as a teenager even though it's not my thing anymore really. But you can't argue with nostalgia.
02:48:17 <DHess_US> They need to make one of these which plays Yakety Sax when you are trying to catch a parakeet, https://www.amazon.com/RESTCLOUD-Insect-Butterfly-Handle-Extends/dp/B07JZ5LL7K/
02:48:19 <EEVBot> [Title] - Sorry! Something went wrong!
02:48:23 <Nothing\> I used to love punk as a teenager
02:48:41 <Kuschelpony> for me its not nostalgia, but a specific kind of Sound
02:48:47 <DHess_US> I still like my teenager age music.
02:48:53 <Kuschelpony> and large dynamic range
02:48:59 <Nothing\> black flag, operation ivy, rancid, dead kennedys, misfits of course etc
02:49:13 <Nothing\> Kuschelpony, yeah i was kind of into everything except country and western
02:49:14 <DHess_US> Def Leppard, Depeche Mode, Cinderella
02:49:20 <Kuschelpony> and dynamic range, it has to breathe, not flat pressed loud
02:49:35 <Nothing\> and what i call "the black arts" which is basically any music associated with black people like rap, r&b, hip hop etc
02:49:38 <Nothing\> it just wasn't my thing
02:49:44 <Kuschelpony> Scorpions, Barclay james Harvest, Pink Floyd, Europe
02:49:54 <Kuschelpony> but today more indipend artists
02:50:01 <Nothing\> yes pink floyd was the first classic rock i ever got into
02:50:13 <Nothing\> finding my dad's old LPs while i was a teenager discovering drugs
02:50:42 <Nothing\> pretty sure my mum knew something was up when she'd come in my room to find my laying on the floor in the dark listening to dark side of the moon with a bucket of vomit next to me
02:50:49 <Nothing\> ahhh lol
02:50:53 * Nothing\ sighs :/
02:51:00 <Nothing\> so much waste
02:51:27 <Nothing\> speaking of regrets
02:51:29 <Kuschelpony> oh and the old Mike and the Mechaniks, not when they came back
02:52:19 <Nothing\> when i was a kid, my dad invested me in this new firm that was just coming onto the market. Put $500 into it and then a few years later cashed out something like $1200 when he left my mum and didn't give me any
02:52:29 <Nothing\> that firm was Berkshire Hathaway
02:52:42 <Nothing\> when he invested my money, it was worth 20,000
02:52:48 <Nothing\> today it's at 430,000
02:53:00 <Nothing\> lol
02:53:42 <Nothing\> still i'm not so regretful about it because i didn't get the money either way
02:53:59 <Nothing\> but i have no doubt he regrets cashing out when it was still only worth like 50,000
02:54:21 <Nothing\> or selling all of the gold he owned in the early 2000s
02:55:03 <Nothing\> ooh i know a little project i can do
02:56:05 <Nothing\> i've got a formula for the output voltage of an RC filter, i should work out some predictions then use my function gen to play out the experiment and see how close my predictions were
02:56:44 <Nothing\> it's too bad, in my haste to buy a function gen i didn't realize this one hasn't got a sweep function but that's alright
02:57:23 <Kuschelpony> for that, some audio analyzer programs are very useful, as you can put out an frequency sweep on the soundcard and record thefiltered result
02:57:29 <Nothing\> although if i wanted that it probably would have gone from $100 to like $250
02:57:45 <Kuschelpony> the fancier ones even make impedance calculations from that
02:58:23 <Nothing\> Kuschelpony, heh before i got this what i would do is use an audio function gen on my mum's phone and I had an audio cable with a 10ohm resistor in series i could just use as my output
02:58:43 <Nothing\> it only gave like 300mvrms but still it worked
02:58:47 <Nothing\> sort of
02:59:16 <Kuschelpony> hihi reminds me of a thread i read recently on diyaudio
03:00:23 <Nothing\> Kuschelpony, they made the display really confusing. For the frequency it shows it as, well say I have a frequency of 6891325.59hz it would show it as 6'891'325.59 which you see a ' in the context of frequency (angular velocity) you think arc minutes.
03:00:28 <Nothing\> so it threw me off at first
03:00:45 <Kuschelpony> someone is searching for an line level "preamplifier" that outputs cbeyond 200V because he wants to bring an very well made coupling transformer into saturation to get that vintage distortion
03:01:13 <Nothing\> that's an awfully high gain for a preamp
03:01:27 <Nothing\> though i know little about amps i was under the impression a preamp had little gain
03:02:42 <Nothing\> i always wondered about audiophiles who swear by tubes and vintage equipment
03:02:46 <Kuschelpony> usually you need none at all, except for that special guy who wants to bring an coupöing transformer (with huge reserves) into saturation beyond any reasonabe voltage
03:02:59 <Kuschelpony> uhm... i would not call them "Audiophiles"
03:03:04 <Nothing\> especially tubes. I've always wanted to see somebody do a double blind test to see if they can tell the difference
03:03:12 <Kuschelpony> theright word is "Audiophools"
03:03:17 <Nothing\> Kuschelpony, i use the term out of convenience
03:03:22 <Nothing\> heh
03:03:29 <Kuschelpony> oh its easy to hear a difference with complex music, you hear the distortion...
03:03:44 <Nothing\> ah
03:04:00 <Kuschelpony> its called euphonic distortion, because some people enjoy some kind of distortion
03:04:00 <Nothing\> i've always wanted to do the same thing with wine tasters
03:04:09 <Kuschelpony> the same species...
03:04:25 <Nothing\> Kuschelpony, it's wabe sabe
03:04:56 <Nothing\> a... i think buddhist or hindu concept which says the small flaws you find in things makes them more beautiful than if everything was perfect
03:05:05 <Kuschelpony> i am one who loves complex music with minimum distortion, espically nothing that cips or messes with dynamics
03:05:13 <Nothing\> pretty sure it's buddhist
03:05:20 <Nothing\> it sounds east asian
03:05:21 <arch> hmm..out of the blue, my computer's psu fan has started to spin really fast. im not even putting any loads on it. i'll see if it's dusty later
03:05:40 <Nothing\> arch, it always alarms me when my cpu fan spins up fast for any reason
03:05:47 <Kuschelpony> but others can perhaps enjpy the kind of singer&acoustic guitar combo with the right kind of distortion making voices more "earthy" and so
03:05:54 <Nothing\> i dunno why. I guess i don't like hearing when my computer is being taxed.
03:06:12 <Nothing\> tangible reminder that i'm shortening its lifespan. However little.
03:08:09 <Kuschelpony> hmm, seems i have not really other options that to order direct from https://www.hjkbstore.com/

04:45:57 <Kuschelpony> thats the "Valley fill" a kind of almost-PFC rectifier
04:47:24 <Kuschelpony> it works in a way that on the Peak of the AC two electrolytics are charged in series, but reconnect to be in paralell for discharging while the rectified line can still add some current below the peak voltage
04:47:42 <coppice> If you listen to a high quality reproduction of recorded music in any way that differs from live it doesn't sound right, because of the way our hearing works. A simple aspect of this is the use of "loudness" controls in a lot of audio equipment, to equalise differently as you turn the volume control. This mimics non-linearity in human perception that has been understood for a century. So, there is no fundamental reason why altering the
04:47:43 <coppice> reproduction of a recording should not make is sound better. However, most audiophool stuff is just deranged.
04:48:45 <Kuschelpony> coppice, yes
04:50:01 <Kuschelpony> i was not writing about "correction" for example in the way that a "loudness" equalizer adapts the tonal balance to different calibrations of the reproduction volume
04:50:18 <Kuschelpony> i was writing about adding distortion because some people prefer it
04:51:20 <Kuschelpony> things like "opamp rolling" or weird configuration of mains cables are a third category, where the effects are either placebo or audible effects of very misguided device construction
04:51:54 <coppice> Its not unreasonable that some alteration of harmonic content with listening conditions might make something sound better. However, this euphonic stuff just sounds worse and worse the more you add. People need to listen to live music more often
04:52:43 <Kuschelpony> yes!

04:53:57 <Kuschelpony> im surely not the kind of "golden ear" but at least someone who doies get fatigued from modern tastes of music alterations to make them mobile friendly
04:56:14 <Kuschelpony> oh and at Ysjoelfir thanks for sharing your life story in the forum
04:56:25 <Kuschelpony> one day i really shouldregister there as well
04:57:10 <rust_collector> lots of the "music" I listen to, sounds like shit live, but is nice in a recording
05:03:47 <coppice> I've started using speakers, after years of listening to most things through headphones. Newer recordings seem to be focussed entirely on headphone listening, and there's no sense of a sound stage played through speakers. Older recordings sound much better through speakers.
05:05:47 <Kuschelpony> hmm, are they focussed on headphones? or are they starting to get focussed to mono playback through one squeaker? i honestly dont know as i dont follow that stuff
05:06:33 <coppice> I think they are focussed on a market where people listen to most things from their phones
05:06:52 <Kuschelpony> yep
05:11:39 <coppice> I hadn't notice the sounds stage getting bad until I bought good speakers 2 years ago. Through headphones things tend to sound pretty good. If you focus on headphones you can use things like HRTF techniques and get some amazing results, Focussing on speakers requires a different approach
05:12:45 <Kuschelpony> im picky about sundstage, so i got 25% happy when i finished my set of wideband speakers
05:13:23 <Kuschelpony> the other 75% ehm well there are recordnings that sound even worse when you have speakers without group delay issues :)
05:16:35 <coppice> It depends what's wrong with the group delay. If its causing interference effects between drivers, that's obviously bad. However, in absolute terms it depends on the frequency range. Human hearing can't detect most phase effects above 2kHz, which is a key reason why DCT based audio compression works so well
05:18:02 <Kuschelpony> i meant it in that way, that on bad enough threeway speakers you can not much disinguish between careful and bad recordings, they all sound in some way diffuse
05:18:34 <Kuschelpony> on widebanders a good recording sounds focused, you can pinpoint instruments
05:18:55 <Kuschelpony> a bad recordings stays a diffuse cloud that you cant focus to a sharp image
05:19:56 <Kuschelpony> the only bad thing about them is that somewhere around 2 to 5 watts they get nonlinear into audible cone breakup modes
05:22:25 <coppice> Directionality can be an issues, too
05:23:26 <Kuschelpony> yes, but not in this room here
05:23:50 <coppice> There have been some good coaxial designs, avoiding all the variable delay issues as you change angle, and they pretty much have to do a good job with the phase, or the coaxial drivers beat hard against each otehr
05:25:56 <Kuschelpony> right
05:27:29 <Kuschelpony> many years ago i had heard an project where someone took an PA coax, with horn tweeter inside a 25cm midranger, but optimized if for hifi, that sounded amazing
05:27:50 <Kuschelpony> old memories to people i cant even remember the name :(
05:29:55 <coppice> when I was a kid there were a lot of high quality single driver speakers, using 10" or 12" drivers with a variable cone, that could really push some air at the bass end, and still sound god at high frequencies.
05:31:26 <Kuschelpony> these were never common in germany
05:32:04 <Kuschelpony> the best commonly available were 16*25cm oval speakers plus 10cm cone tweeters
05:32:17 <Kuschelpony> i have a set i want to use for e retro project one day
05:32:51 <coppice> They were common the UK in the 1960s, then through the 70s the public developed the mindset that good speakers needed woofers and tweeters, and I think it killed the market.
05:34:06 <coppice> In the 70s I was a great lover of Japanese speakers, They generally seemed much better on percussive sound than things made in Europe or America. Possibility because their music made that a priority.
05:38:03 <K> yall trying to make me feel bad about buying those cantons, eh
05:38:31 <Kuschelpony> oh canton also had good ones
05:38:47 <coppice> If you want to see an audio company producing great results at value for money prices look at much of what Pioneer made in the 1970s.
05:40:39 <K> buying used but sizeable non-ussr stuff here is too much hassle
05:41:41 <K> shipping is costly, and i would find it risky
05:42:19 <K> not that it would not arrive, but in what shape/number of pieces
05:43:31 <Kuschelpony> i love their hifi receivers, in that silver design with the soft cyan illuminated scales
05:50:24 <coppice> There were some terrible amps and receivers in the 70s, when they fell into the stupidity of chasing testing results, while measuring all the wrong things. There was a backlash to that in the 80s, when things started sounding too bad, but you still see so much of that. Te audiophools are no dumber that the people who say it must test well, while only doing static tests. If I want to listen to a continuous sine wave all day, I might be in
05:50:25 <coppice> in those static results.
05:50:39 <coppice> Pioneer largely sidestepped that
05:52:06 <coppice> There are 70s receivers that are flat from 20Hz to 1MHz. They have so much bandwidth that any tiny non-linearity in the system meant you can hear AM radio from the speakers, when you haven't selected the tuner.
05:52:08 <Kuschelpony> yeah... a sinewave harmonic distortion test does not reveal things like dynamic effects of wobbly supply rails and rc time constants for bias voltages
05:54:10 <coppice> if a transient drives some designs into saturation they recover almost instantly. For many the transient throws off their biasing for a considerable period. Super high gain with massive feedback test well, statically, but often gives horrible transient IMD. Those were the two biggest issue in a lot of 1970s amps, and you still find some of it today,
05:54:49 <Kuschelpony> i know
05:55:20 <Kuschelpony> worst were perhaps some grundig designs where they ac coupled driver stages and final transistors
05:56:27 <Kuschelpony> at least they could not go into "shoot through" mode but in the other direction a transient clipping could charge the coupling capacitor and give a large "thump"
05:57:56 <coppice> when I bought speakers 2 years ago they used a 700 pound Cambridge Audio amp to demo them. After trying a few speakers, and being unimpressed, the guy changed to the next model up the Cambridge Audio range, at 1000 pounds, which is supposed to be very similar except for the power output. The sound was very different, even though we were not listening very loudly. In 2020 even a 100 pound amp should be so good that nothing sounds clearly
05:58:46 <coppice> large thumps at turn on have been very common over the decades
05:59:41 <Kuschelpony> not on turn on, but after clipping that throw off the charge level of the ac coupling capacitor between driver and final transistors
06:00:15 <coppice> they thump during transient recovery? that's nasty
06:00:29 <Kuschelpony> yeah..
06:00:39 <Kuschelpony> that design was alreydy shit in the 70s
06:00:59 <Kuschelpony> as said, the driver and final transistors were ac coupled
06:01:33 <Kuschelpony> on the positive side, any failure could at most destroy the two final transistors but not shoot through anything before
06:02:49 <Kuschelpony> in differencde to the usual kind of full dc coupled amps where any failure goes backward and could take out almost all transistors and smoke resistors
06:03:46 <Kuschelpony> in my time as dervice technican in the 90s and 00s i got all the exotic stuff on my bench, that noone else around did understand
06:05:26 <Kuschelpony> another favorite, reel to reel tape decks with actively regulated tape tension, from a kind of primitive electro-optic force transducer (that failed from creeping plastic parts) to current drivers of the reel motors
06:05:51 <Kuschelpony> trying to remember who made them, i think Akai was it
06:07:00 <Kuschelpony> the old techs did only understand full mechanic tape brakes, the young ones did not want to touch that old clunky stuff, in between was me doing repairs for many loyal old clients
06:08:09 <Kuschelpony> sorry for the wall of text i really need to go sleeping soon
06:08:23 <Kuschelpony> happy to discuss forther tomorrow

10:42:14 <MrMobodies> Hello
10:43:08 <DogWomble> good morning
10:44:09 <MrMobodies> Batter came
10:44:18 <MrMobodies> and this time much better
10:44:31 <MrMobodies> only one tiny dent on the top cover but no cracks
10:44:48 <MrMobodies> they also improved in the packaging
10:47:16 <MrMobodies> Now I got two ups

10:49:28 <MrMobodies> I filmed it this time just incase the battery turned up wrecked in some wy
10:49:36 <MrMobodies> but this time it seems okay
10:49:50 <MrMobodies> do you think that little dent will cause problems?
10:50:03 <MrMobodies> https://i.imgur.com/cfS7oJi.jpg
10:50:37 <MrMobodies> The left ups, is doing the cupboard and lighting in there
10:50:53 <MrMobodies> and the right ups is doing some switches and monitoring stuff
10:51:04 <MrMobodies> I have another battery arriving for the left ups
10:53:45 <MrMobodies> I put that one in the right and pulled this one out
10:53:46 <MrMobodies> https://i.imgur.com/k6ELVUO.jpg
10:53:54 <MrMobodies> I don't trust it
10:54:10 <MrMobodies> It looks me to like Powersonic clone
10:54:21 <MrMobodies> and check out the bad grammmr
10:54:26 <MrMobodies> *grammar
10:54:39 <MrMobodies> no spaces are commas
10:55:18 <MrMobodies> I only brought the UPS with it in because i can see it working but had no plans to use it past that point
10:55:41 <MrMobodies> or do you think I am being paranoid?
11:03:31 <Ampera> hello MrMobodies
11:03:32 <EEVBot> Hello, Ampera!
11:03:32 <Ampera> how are you doing
11:03:36 * Ampera deletes EEVBot
11:09:03 <MrMobodies> Hello
11:09:09 <MrMobodies> just a bit tired
11:09:23 <MrMobodies> I had 3 shots of Irish cream down the pub
11:09:32 <MrMobodies> and I just woke up 4 hours later on my chair
11:09:34 <Ampera> nice
11:09:41 <Ampera> I just had a bunch of pizza and hot wings
11:10:03 <MrMobodies> I like hot wings
11:10:13 <MrMobodies> the spicy wet things with the breadcrumbs
11:10:17 <MrMobodies> oh battery
11:10:42 <MrMobodies> oops
11:10:45 <MrMobodies> *battered
11:10:47 <Ampera> no, they're not battered
11:11:06 <Ampera> these are buffalo hot wings, so they're just deep fried chicken wings (with no batter) covered in a tangy sauce
11:11:24 <Ampera> typical NY pizza restaurant wings
11:11:27 <MrMobodies> sounds very nice
11:11:43 <MrMobodies> kind of waking me up a bit
11:11:55 <Ampera> ended up buying four 18" pies, and 20 hot wings
11:12:20 <Ampera> brb, need to shave
11:12:26 <MrMobodies> what kind of pies were they?
11:13:57 <MrMobodies> a couple of days I had to buy a new razer. It is suppose last for 18 months
11:14:15 <MrMobodies> but it is more like a year until it don't seem to cut well
11:19:36 <Ampera> MrMobodies, pizza pies
11:19:47 <Ampera> also that's quite a long lasting razor
11:19:59 <Ampera> I shave very sparingly, yet my blades only last 1-2 months
11:27:54 <MrMobodies> Pizza pies, never had one before but
11:27:54 <MrMobodies> https://imagesvc.meredithcorp.io/v3/mm/image?url=https%3A%2F%2Fstatic.onecms.io%2Fwp-content%2Fuploads%
11:28:00 <MrMobodies> they look good
11:28:09 <MrMobodies> as i was searching for the blade replacement
11:28:33 <MrMobodies> I came across this thing that looked a bit frightening to me:

11:59:09 <MrMobodies> I know someone at the local pubhouse who, well they use eye scanner and password
11:59:31 <MrMobodies> for their entry into building
11:59:36 <MrMobodies> which is high security stuff
11:59:45 <MrMobodies> to do with data storage
12:00:46 <MrMobodies> and someone else told me they use a thumbprint and eyescanner at another place to do with working for access control

18:06:20 <Kuschelpony> sooo now i have also a piercing, or to be exactly 14 of them in a 2,54mm grid :(
18:06:52 <Kuschelpony> one more reason i should only use SMD in future
18:07:17 <Ysjoelfir> no way, you let yourself pierce with a DIP14? that is sooo cool! I considered getting an electronics tattoo some times, but didn't come up with a good motiv
18:07:49 <Kuschelpony> i did it not on intention...
18:07:56 <Ysjoelfir> oh
18:08:04 <Ysjoelfir> you should not drop your DIPs than
18:08:40 <Kuschelpony> i have not even an idea when i dropped it, that must have been a while ago
18:08:58 <Kuschelpony> just found it back in an place i do usually not do electronics, by going barefoot
18:09:21 <Kuschelpony> at least i know a very good motive for a tatoo, the wilkinson power divider
18:09:33 <Ysjoelfir> I would notice such things pretty quickly, as I am going barefoot in ma apartment basically all day
18:09:56 <Ysjoelfir> what is said divider?
18:10:43 <Kuschelpony> "Widerstand ist NICHT sinnlos"
18:10:51 <Kuschelpony> its the Y-shaped microwave thingie
18:10:58 <Ysjoelfir> aaaaah that one
18:11:36 <Ysjoelfir> thats not the worst idea, yes. but otoh, I am not a high frequency guy and probably would have to explain it quite a bit xD
18:11:45 <Kuschelpony> where the resistor appears in a place that appears for the DC people as shorted out, but for the working frequency it sees 180° of the unwanted reflections so it absorbs that power
18:12:10 <Ysjoelfir> yep, I remember now which one that was
18:12:25 <Kuschelpony> the freak will notice, the others, well do you really care about them :)
18:12:43 <Ysjoelfir> thats true. I think I will put it onto the suggestions list :P
18:13:20 <Kuschelpony> im currently undecided, should i try my luck again and make some wood working attempts, or should i avoid getting more injured

18:14:28 <Ysjoelfir> oh, you are also into woodworking? I just finished clearing up my woodworking bench in the basement on friday, after having used it only for putting stuff I am not using right now since I moved in here
18:14:30 Join: form ([email protected]) to #EEVblog
18:15:36 <Kuschelpony> im not realy into woodworking, just enough of it to build speaker boxes and some cases or primitive furniture
18:16:01 <Kuschelpony> my father was professional woodworker so i can use his workshop
18:16:08 <Ysjoelfir> oh nice!
18:16:35 <Kuschelpony> i have one minor project on my wish list, its a clone of a "Stereolith" speaker
18:17:10 <Kuschelpony> thats a kind of three speaker matrix in a single box, which uses the reflections from the room walls to have some stereo imaging
18:17:12 <Ysjoelfir> those small heavily rounded square ones?
18:17:23 <Kuschelpony> hmm no idea
18:17:34 <Kuschelpony> its meant as portable box for my laptop
18:19:03 <Ysjoelfir> let me check if I find a pic. but I didn't know the reason for that design
18:19:16 <Kuschelpony> lets see if someone knows

18:21:49 <T3sl4> Kuschelpony: fuckin yeouch
18:22:29 <Kuschelpony> hmm that design looks different
18:24:33 <Kuschelpony> what i mean is a design with three speakers, the front one giving 0,5*L+0,5*R and the left and right one about R-0,5*L and L-0,*R
18:26:18 <Ysjoelfir> thats interesting
18:30:31 <Kuschelpony> searching diyaudio for the relevant thread
18:33:34 <Kuschelpony> https://www.diyaudio.com/community/attachments/1645781814395-png.1029042/
18:34:27 <Ysjoelfir> that is simple but - if it works - brilliant
18:34:40 <Kuschelpony> i have not yet heard it but it looks promising
18:35:43 <Kuschelpony> in between the other non-electronic projects that are frustratingly stuck in all ways perhaps something that is a bit more leading to an positive end
18:36:22 <Ysjoelfir> I know this stuck projects problem.... its annoying
18:37:30 <Kuschelpony> yeah, people push the delivery date, or disappear without traces
18:37:56 <Kuschelpony> its much more problematic if its an artwork thing and you have worldwide only a few people who have the skills and want to do
18:38:13 <Ysjoelfir> that sounds serious o.o
18:38:54 <Kuschelpony> well, i do have more han a dozen crazy fun projects that i am trying to start since a decade and most are somewhat stuck or put "on ice"
18:40:10 <Kuschelpony> currently trying again to find if i can get a specific snorkel mask in any european shop
18:47:10 <Kuschelpony> summer is near and it looks like we are low enough on the C-thing to look to go out to beaches again
18:48:50 <Kuschelpony> sorry thats perhaps too offtopic here again
18:51:12 <Ysjoelfir> Thats fine, I think we are mostly talking off topic anyways all the time?
18:52:26 <Kuschelpony> mmh i hoped the speaker project is still on topic :)
18:53:53 <Ysjoelfir> sure, but snorkling is cool as well
18:54:20 <Kuschelpony> i want to restart this year
18:54:41 <Kuschelpony> its more than a decade ago
19:01:18 <Kuschelpony> http://elias.altervista.org/html/SingleSpeakerStereo.html
19:13:59 <Ysjoelfir> Very interesting, I just read that. and now I want one
19:14:45 <Kuschelpony> hihi same here, but the speakers and particle borad are already waiting
19:15:41 <Ysjoelfir> Hehehe. I wonder if that could work on my balcony, as its more or less confined on three sides
19:16:47 <Kuschelpony> it seems it basically needs either one large wall behind or beeing placed a bit in front of a corner
19:23:01 <Ysjoelfir> that might be possible than. hmmm
19:27:45 <Kuschelpony> hmm maybe one day you get a paket with not only the speakers but also other things to try out
19:28:25 <Ysjoelfir> lol
19:28:32 <Ysjoelfir> :P

23:37:52 <rust_collector> I like the idea of those speakers. Interesting things
23:38:06 <Ysjoelfir> I am actually not, I am cooking and planning things. but.... meh. I think I need some distraction from time to time.

23:38:52 <Kuschelpony> i meant small peak
