48:00 * steve30 relaxes and purrs
04:38 <hsn> yes
53:21 * DHess_US notices that the anode connection lead is frayed, sending a 21 kilovolt discharge into steve30.

23:58 <arch> etching this soon: https://i.imgur.com/9CIj8AK.png
34:11 <Kuschelpony> hmm, lusting again to build a "Doc Brown" guitar amplifier :) wollen wir doch mal Doc Brown - Gitarrenverstärker bauen :) https://www.ebay-kleinanzeigen.de/s-anzeige/roehre-tube-telefunken-rs630/1752872781-172-9470

26:25 <arch> i made some slight changes, to split up the power ground from the more sensitive ground used by the opamp (lm324, that 14 pin DIP there). my single point ground ref is that pin header J4. looking good i think: https://i.imgur.com/XoMYYoY.png
27:29 <arch> https://i.imgur.com/HcDtNf4.png
28:02 * T3sl4 drills a via in arch
28:39 <arch> those vias are just locations where im placing overhead magnet wire jumpers
29:13 <arch> so there are 12 overhead jumper wires
29:38 <arch> with this project, i will finally put my GTX580 to rest. it's been a long 4 years, gathering dust doing nothing
29:49 <arch> now i can use it as a CC load lol
30:24 <arch> i had to put a boost section cuz that fan at 5V is pretty slow, and wont dissipate much heat, so i made it output 8V or so
30:58 <arch> might make it 12V actually. assuming the soft start is decent on that boost section
31:47 <arch> inrush current is about 2A without any inrush current limit, at 12V. but it drops down to 0.7A at 12V once it's up to speed
32:41 <arch> it's that TS19375 voltage mode boost controller that you puked at. so i get to test that out with ceramic caps to see if it's stable
32:49 <arch> the one that called for 30mOhm-100mOhm ESR
33:10 <arch> two projects in one, in a way
33:46 Quit: Kuschelpony ([email protected]) Connection closed
33:49 <T3sl4> yey
35:42 <arch> i will see you weirdos later. gonna game a bit

19:23 <Nothing\> heyo
19:35 <Nothing\> got a question for you guys i KNOW somebody here knows the answer to
20:57 * electrohead slaps Nothing\ with virtual information
20:59 <Nothing\> i remembered an episode of eevblog where dave was talking about this guy who owned a big computer computer, i think atari or commodore or something, but he had this way of vainly trying to keep the price point down by having his engineers remove bypass caps one by one and see if the system still works
21:09 <Nothing\> hey electrohead how's it going?
21:25 <+electrohead> it goes, how about you?
21:29 <Nothing\> but anyways i can't remember the guy's name or what company it was and it's bugging the hell out of me
21:34 <Nothing\> it's going pretty good
21:35 <+electrohead> and I think I slightly remember that
21:57 Join: modrobert ([email protected]) to #EEVblog
22:00 <Nothing\> yeah i was just explaining it to my mom and can't for the life of me remember his name or company
22:06 <Nothing\> i think his name started with an M
22:44 <Nothing\> weird i just found a hair actually baked into one of these pot cookies lol
22:53 <Nothing\> fucking cat shedding all over the place
23:12 <Nothing\> i'm constantly pulling his hair out of my mustache or from between my lips
24:07 <Nothing\> MUNSEN!
24:10 <Nothing\> that was his name
24:23 <Nothing\> now what company did he own
25:42 <Nothing\> nernst tube? wtf is a nernst tube?
28:43 <+electrohead> https://edisontechcenter.org/NernstLamps.html
28:44 <EEVBot> [Title] - The Nernst Lamp - How it works and history
28:58 <+electrohead> you're thinking of that, and photonic induction just did a video about that
31:46 * electrohead offers home made wine
49:04 * Ampera hugs electrohead and Nothing\ 
53:28 <Nothing\> electrohead, heh yup that's what caused my questioning of it
53:57 <Nothing\> i saw a wiki article a while back for this weird type of early memory that used a cathode ray tube
54:07 <Ampera> mmm williams tubes
54:10 <Ampera> those are neat
54:12 <Nothing\> yup
54:15 <Nothing\> they really are
54:18 Join: Guest69 ([email protected]) to #EEVblog
54:20 <Nothing\> here's one for you Ampera
54:21 <Ampera> along with acoustic delay line memory
54:29 <Nothing\> oh yeah that's an awesome idea
54:44 <Nothing\> i like that too, but you'd think it'd be hard unless the line was taught
55:06 <Nothing\> but it's just all flapping in the breeze, i don't even think the main coil is supported by anything, is it?
55:40 <Nothing\> like it just has supports on the start and end of it, but none through the middle. Probably cuz any in the middle would lower the Q factor, ie increase dampening
56:03 <Nothing\> Ampera, ever heard of, oh shit i think they're called magnetic amplifiers
56:20 <Ampera> No I haven't heard of, "oh shit I think they're called magnetic amplifiers"
56:39 <Nothing\> it's an amplifier that has only passive components in it that uses some sort of choke or transformer to amplify the signal. But it's genuine amplification. Not just a step up transformer.
57:13 <Nothing\> i was confused when my friend tried to explain them to me cuz i was like "yeah that's called a step up transformer"
57:26 <Nothing\> and he's trying to explain the difference while it's just going over my head
57:48 <Nothing\> https://en.wikipedia.org/wiki/Magnetic_amplifier
57:49 <EEVBot> [Title] - Magnetic amplifier - Wikipedia
57:53 <Nothing\> there's the wiki article
58:06 <Nothing\> ugh i ate too many cookies
58:30 <Ampera> who stole the cookies from the cookie jar
58:36 <Ampera> Nothing\, did you steal the cookies from the cookie jar?
58:40 <Nothing\> damn straight
58:43 <Ampera> why did you steal the cookies from the cookie jar
58:43 <Nothing\> and i do it again
58:55 <Nothing\> cuz it makes me feel like a big man
59:25 <Nothing\> man, i'm watching too much simpsons if i'm quoting them more than once a minute
59:30 <Ampera> obviously the manlier of the option is to simply bake more cookies and start learning to bake
59:39 * electrohead bakes Nothing\
59:46 <Ampera> nothing manlier than combining chemistry with fire and then eating it
00:02 <Nothing\> lol i can bake the cookies fine. I just need my mum to dollop the dough balls out cuz i always screw it up
00:14 <Nothing\> something about a woman's touch makes baked goods better
00:50 <Nothing\> and that something becomes exponentially more powerful with each generation she and her offspring produce
01:22 <Nothing\> lol i used to make these peanut butter cookies that were the easiest thing in the world to bake
01:34 <Nothing\> you basically just mix sugar and peanut butter, then bake it
01:47 <Nothing\> comes out like perfect cookies
02:00 <coppice> There were some interesting delay line memory demos in the 70s that never really went anywhere. Like you take two large piezo sensitive crystals. You put then between plates where you can discharge a burst of high voltage. You grind a flat on each crystal and fit a transducer. Now you stream data into one crystal, and let it wash around insode the crystal. Then you whack the crystal with an electric pulse, and the make the signal reflect along
02:02 <coppice> entire length, and flow back out of the input transducer. You copy this stream into the other crystal, and when its all out of the first crystal and inside the second, you whack the second crystal and reverse the process
02:03 <Nothing\> i got the recipe off of a jar of peanut butter years ago
03:06 <Nothing\> coppice, hell, nevermind delay line memory of the 70's. They've had tons of neat and novel solutions for memory throughout the era of computers
03:09 <Ampera> coppice, what I'm wondering is why normal coils of wire were never used as delay line memory
03:55 <coppice> Ampera: coils of wire were used for a while
04:29 <Nothing\> was there any sort of method for dampening external noise on those things?
04:50 <Nothing\> with the delay line just hanging in the breeze like that, i could see any little vibrations causing a huge snr
04:58 <Ampera> I'm kinda wondering why it wasn't more popular, even to this day. I imagine with the right circuitry, you could store a lot of information simply in the form of electrical force inside a wire
05:25 <Ampera> Nothing\, the short answer is, to my knowledge there wasn't much
05:40 <Ampera> you banging the table and corrupting all the memory was simply solved by you not banging on the table
05:48 <Nothing\> lol
05:57 <Nothing\> well you could still accidentally kick it
06:07 <Nothing\> or i used to use my computer as a foot rest
06:07 <Ampera> there's a reason we don't use it anymore :P
06:08 <Nothing\> so
06:50 <Nothing\> why not make optocoupler based memory
07:02 <Nothing\> where LED on = 1 LED off = 0
07:21 <Nothing\> or something like an optocoupler where you have an LED and a light sensor
07:38 <+electrohead> but you still need power
07:40 <Nothing\> but that'd be real bulky cuz you'd have to optically isolate each memory cell from the other
07:49 * electrohead powers up Nothing\
07:59 * Nothing\ dances a merry little jig
08:09 * T3sl4 straps Nothing\ to a jig, probes it
08:19 <Nothing\> lol
08:26 <Ampera> using fiber optics as a delay line would also be another idea, and would avoid a lot of problems regarding EMI
08:35 <Nothing\> my mom taught me never to use my probe in public
08:50 <+electrohead> that's a good thing
08:52 <+electrohead> lol
09:10 <Nothing\> and that i can't talk to the vacuum cleaner like R2D2 talks to computers
09:20 <Nothing\> that was an unfortunate trip to the hospital
10:21 <T3sl4> Ampera: wires aren't very good because the speed of light is high relative to the kinds of delays we might like to have
10:32 <Ampera> simply add more wire
10:39 <Ampera> or, even better, more fiber
10:41 <T3sl4> then your signal disappears :P
10:50 <Nothing\> lol when my brother was little he got a toy KITT (the car from knight rider) and he thought just like in the show that his toy was indestructable
10:59 <Nothing\> so he bashed the shit out of it until it was in pieces
11:18 <T3sl4> a lot of color TVs had a crappy delay line of a microsecond or two, with i don't know how much wire, not a lot like a hundred feet or so but more important is how it was arranged
11:27 <Nothing\> he also had a pet squirrel that he killed by throwing it into the air and forgetting to catch it
11:44 <T3sl4> they usually used a phenolic tube, with a strip of foil down the middle, not a full cylinder just a flat piece, and wound the wire around that
12:00 <Nothing\> T3sl4, iirc the speed of light is about 1 foot per 2 nanoseconds
12:04 <Nothing\> on was that 1 meter
12:09 <T3sl4> this has the effect of making a transmission line with a lot of coupling between turns, which slows down the wave, but makes the velocity frequency-dependent
12:18 <Nothing\> i hell i can never remember the speed of light on that scale
12:23 <Nothing\> but it's surprisingly slow
12:29 <T3sl4> the step response looks like this, https://www.seventransistorlabs.com/Images/DelayLineResponse.jpg
12:54 <T3sl4> basically, you get the delay you want, but only up to a cutoff frequency, above which it's just bonkers
13:11 <T3sl4> in short, the bandwidth-delay product is the real challenge
13:43 <T3sl4> as for fiber, you're quite right, it's moderately affordable, while offering extraordinary bandwidth (Gbps)
14:27 <T3sl4> there's a market exchange that's supposed to be routing trades through a bucket of fiber plus repeater amps, to force all participants to the same delay to equalize high frequency trading
14:49 <T3sl4> https://hackaday.com/2019/02/26/putting-the-brakes-on-high-frequency-trading-with-physics/
14:50 <Nothing\> lol @ my mom complaining about ads that show footage that isn't actually in-game footage
14:51 <EEVBot> [Title] - Putting The Brakes On High-Frequency Trading With Physics | Hackaday
15:00 <Nothing\> she's getting way too into the internet
15:05 <Nothing\> for a person of her ago
15:06 <Ampera> Tom Scott had a video on that
15:06 <Nothing\> age
15:11 <Nothing\> oh really?
15:26 <Nothing\> oh, high frequency trading you mean
15:52 <Nothing\> yeah i remember that. talking about how the buildings closer to the exchange were more desirable cuz there was less delay in purchasing stocks.
16:12 <T3sl4> heh, curiously the h@d page turned up first result, which links tom's video
16:54 <Nothing\> it's sad that the days of having thousands of people packed into a small building yelling about soy and waffles at eachother and making obscure hand gestures

17:31 <Nothing\> ska haha
17:34 <Nothing\> that existed!
18:01 <Nothing\> i watched a video the other day about danzig's "evil" bricks lol
19:20 <Nothing\> basically just a pile of bricks he kept in the front yard of his dilapidated hollywood hills home until his neighbours complained about how it affects their property values so he went out and started chucking the bricks into a dumpster while screaming about his neighbours lol
19:47 <Nothing\> then people figured out where he lived and wouldn't leave him alone so he sold his completely run down shithole home for $1.2 million
20:26 <Nothing\> which nowadays, there are regular middle class homes in vancouver that sell for more than that. Never mind a run down house in the Hollywood Hills.
20:42 <T3sl4> tell your children not to walk my way, what you hear what you say, neighbo-o-or
21:07 <Nothing\> hell, i grew up in a big upper-middle class style house and it sold for less than $200k when we sold it
21:18 <Nothing\> nowadays a house like that would go for $600k easy
21:42 <Nothing\> kinda frustrating in retrospect to think if we'd waited 10-20 years to sell we coulda tripled our money
22:37 <Nothing\> actually i was just reading an article today about how cost of living up north is unrealistic. Like up in the Arctic.
22:50 <Nothing\> For example, a bag of dog food costs $160
23:13 <Nothing\> this woman goes on tik tok and posts pictures of all of the crazy prices
23:36 <T3sl4> gotta ship in everything, ya
23:37 <Nothing\> hrm what else was there
23:41 <Nothing\> yah that's the problem
24:02 <Nothing\> but doubly so, most people up that way are impoverished indigenous peoples-
24:08 <Nothing\> here we go
24:25 <Nothing\> $34 for a bag of snack mix. Like chips and stuff.
24:44 <Nothing\> $70 for a roll of aluminum foil
25:19 <Nothing\> and the woman was saying her neighbour is on welfare. Which for welfare, they give you about $600. Plus a small pittance if you live north of 60.
25:29 <Nothing\> that is, north of the 60th parallel
26:06 <Nothing\> shit, here that's not even enough to cover rent for the most squalid bachelor apartment you can imagine
26:11 <Nothing\> those start at about $800
27:10 <Nothing\> I'm lucky, i only pay $1400 for my 3 bedroom townhouse. But even then neither I on disability, nor my mother on pension could cover the rent on our own. So we have to share living expenses.
28:14 <Nothing\> lol meanwhile there was, I think it was a city councilor from Montreal who tried to claim a middle class apartment starts at $500. In Montreal. Nevermind where I am in a pissant little town that thinks it's a real city.
28:29 <Nothing\> he caught a lot of flak for that one lol
29:46 <Nothing\> yeah, just a 5 second google search shows a 2 or 3 bedroom apartment in montreal goes from $1500 to $2100 average. Probably a lot more for a 3 bedroom
32:00 <Ampera> Rent is hilarious, you pay more than the place is worth to own nothing, have no equity, and if you're in an apartment, have to deal with irritating noisy jackasses all around.
33:14 <Ampera> It's a supply/demand thing and not many people want to be small time landlords, since the amount of liability and maintenance it requires, not to mention dealing with absolute human trash that'll drag you through the courts just to pay you your rent.
46:44 <Halcyon> Speaking of human trash, morning Ampera
47:04 <Ampera> aww Halcyon, you always know how to turn me on
47:13 <Halcyon> :P
47:16 <Ampera> how are you doing
47:33 <Halcyon> Just woke up and showered, about to go out at get a coffee and some coffee beans
47:35 <Halcyon> How are you?
47:41 <Ampera> meh
47:43 <Ampera> my weekend's over
48:10 <Halcyon> Aww
48:29 <Ampera> gonna be sweet when I've been here for 5 years and they give me another week of PTO
48:42 <Halcyon> PTO ?

24:44 <steve30> hi
27:31 <Nothing\> Ampera, lol i was thinking pacific theatre of operation
27:41 <Nothing\> that's what i think when i see PTO
27:51 <Nothing\> hey steve30
27:54 <Nothing\> how's it going?
28:34 <Nothing\> ugh bored
29:08 <Nothing\> i need to go to the dollar store and get some binders and dividers and folders for all of this stuff i've printed and need to print
29:10 <steve30> i went out earlier, then i came back and had some curry
29:15 <Nothing\> mmm tasty
29:37 <Nothing\> i just ate a dozen pot cookies for my breakfast
30:12 <Nothing\> too many cookies
30:35 <Nothing\> i'm glad i didn't eat anymore cuz i was feeling sick after that just from eating so many cookies
31:37 <steve30> On that subject, my Mum was pondering trying CBD oil, since it cures pretty much everything these days
32:42 <Nothing\> or so they say
32:51 <Nothing\> honestly, there's no harm in trying it
32:58 <Nothing\> it's not intoxicating like THC is
33:32 <Nothing\> i'm not sure about american vendors, but redecan's a good vendor here if you can order it online
34:25 <Nothing\> although i'm pretty sure you could smell/taste if it's actually got CBD in it. There's still the matter of whether they put the actual amount in it the label says or if they short you.
35:27 <Nothing\> i tried THC oil and it was basically some sort of vegetable oil infused with THC. Had a very distinctive taste of cannabis so there's no faking it.
35:36 <steve30> It doesn't really have any regulation here in England as its not considered a medicine.
35:56 <Nothing\> yeah that's the tricky thing
36:24 <Nothing\> i bought some CBD oil from a store a year or so before legalization and it didn't seem to do anything for me
37:17 <Nothing\> or failing that, you can buy strains of cannabis that have a high percentage of CBD and next to no THC
37:43 <Nothing\> learn to make your own oil and save a ton of money
37:45 <steve30> well, she said she knows someone who grows her own plants
37:53 <Nothing\> ah right on
38:13 <Nothing\> the only issue with that is the levels of CBD can be pretty variable depending on the strain
38:21 <Nothing\> some strains have no CBD at all
38:22 Quit: Ysjoelfir_BNC ([email protected]) EOF from client
38:25 <Nothing\> others have tons
38:55 <Nothing\> if you know the type of strain it can help to look it up online to get an idea of the levels of thc/cbd in it
39:57 <Nothing\> there are some that can be pretty high in CBD, or others that are meant more as a combination of CBD and THC
40:33 * steve30 knows very little about canabis
40:56 <Nothing\> yeah it can be a lot to take in
41:32 <Nothing\> even for me, when they legalized it and i had so many more options and so much more information about the strains i was getting there was a lot to learn
42:36 <Nothing\> especially that you really can't go on the percentages they list and it's more a trial and error experience to find what's right for you. Especially if you don't wanna spend tons of money.
43:06 <steve30> My Mum takes various 'supplements', and has recently started drinking distilled water (rather than tap water), and is made ill by the excipients in some medications.
43:42 <Nothing\> yeah drinking distilled water too you've gotta watch your electrolyte levels
43:56 <steve30> So I'm guessing the CBD might help even if its a placebo
44:12 <Nothing\> cuz you're not taking in any salts in your water anymore so they can get low if you take in more water than salt
44:22 <Nothing\> sorta like the opposite of drinking salt water
44:31 <Nothing\> steve30, exactly
44:45 <Nothing\> and it's harmless, so you've nothing to worry about except maybe cost
45:30 <Nothing\> here it's about $40CAD for a 30ml bottle but my dad was paying $80 from an actual medical supplier
46:09 <Nothing\> the place i saw it was a government sanctioned dispensary
47:04 <Nothing\> but the extracts can be more expensive since you're paying for the plants, plus the time, effort and materials for making the extract
48:41 <Nothing\> as opposed to if you just get your own plants, learn how to decarboxylate it and make an infusion in some vegetable oil or butter for cooking with or to just take straight up. But taking it straight it can be hard to find an effective dose that isn't overkill.
49:09 <Nothing\> and decarboxylation is basically just roasting it at 250f or so for around 30 minutes
49:18 <Nothing\> after you've ground it up
50:17 <Nothing\> i've looked at the numbers on the packages here and before decarbing it, you have about 10mg of active thc per gram, after decarbing you get around 200mg per gram. So it makes a HUGE difference.
50:55 <Nothing\> oh shit it's almost sunset. I was gonna set up my mom's cell phone and do a time lapse of some fire flies once they come out
51:38 <Nothing\> skies are still blood red from the wild fires up north
52:12 <Nothing\> actually the horizon is a regular peach color, but the bottoms of the clouds are all deep red
52:53 <Nothing\> and it's been so hazy here. You can't even see the town about 5 miles to the north.
53:59 <Nothing\> it's crazy to think we're being affected by wildfires that are burning 1500km away

06:05 <Nothing\> wtf people why fireworks?
06:13 <Nothing\> it's not like it's the greatest holiday ever
06:38 <Nothing\> it's just the civic holiday. Which I'm pretty sure was just invented to pad the time between labor day and canada day
14:45 <EEVBot> [Twitter] - eevblog - Woah, have to get this book! We had Bill on the Amp Hour and he's great https://t.co/RNoWo0hlWg https://t.co/jMMUEmCpjp
16:17 <Nothing\> this here says a 1 inch binder can fit 175 pages-
16:48 <Nothing\> i think that's a bit of a stretch. Even at 100 pages mine won't close right unless i manually move every page to the same side
18:14 <Nothing\> man, you guys need to start talking and stop making me look like a nutter

42:08 <Nothing\> finally trying to figure out the various applications of a tl431 after a year of meaning to go over them
44:21 <Halcyon> Hey steve30
44:29 <steve30> hi Halcyon
44:50 <Halcyon> How are you?
46:05 <Halcyon> Solar is having a good day, up to 7kW in the sun
46:09 <Halcyon> Except there are stupid clouds
46:29 <steve30> i had a good evening with fetish guy, so i'm feeling a bit better today
46:36 <Halcyon> Oh good :)
47:09 <steve30> we made about 5kwH today
47:40 <Halcyon> I've generated 6.1 kWh so far
47:47 <Halcyon> I hate winter :(
51:34 * Nothing\ mocks Halcyon from the northern hemisphere
52:02 <Nothing\> that's okay, it's probably like 20 degrees warmer there in the winter, at least
52:12 <Halcyon> :P
52:35 <Nothing\> have you ever even seen snow?
52:48 <Nothing\> or know what -40 degrees feels like
52:58 <Halcyon> We get snow here
53:03 <Halcyon> But no, it never gets that cold here
53:06 <Nothing\> where is here anyways?
53:18 <Halcyon> Mountainous area west of Sydney
53:36 <Nothing\> ah okay so it's cuz you're in the mountain you get snow? or are you just that far south?
54:08 <Halcyon> We get snow here because of the altitude, but if you go further west, like near Oberon or Bathurst, it shows out there
54:16 <Halcyon> *snows
54:21 <Nothing\> ah right on
54:31 <Nothing\> lotsa ski resorts out that way i'd imagine?
54:37 <Halcyon> Down south there are
54:45 <Nothing\> since it's probably one of the few places in the area you can ski
55:02 <Halcyon> I don't usually go, they are quite touristy
55:09 <Nothing\> yeah i don't care for them
55:30 <Halcyon> Plus I prefer warm weather over cold
55:36 <Nothing\> i lived in a city with a pretty small ski resort with just 16 runs but it was still pretty popular
55:54 <Nothing\> i never bothered going once while i lived there. Though I went a few times as a kid for school.
56:35 <Nothing\> it's fun enough but I hate the cold. Especially now that I'm on meds that make me especially sensitive to it or to sudden changes in temperature.
57:21 <Nothing\> i tried to take my nieces swimming once and felt like i was going to die. If you've ever swum in cold water before and know how it can just suck the breath right out of you.
57:41 Quit: coppice ([email protected]) Quit: Konversation terminated!
57:49 <Nothing\> and this was in an indoor pool lol
58:33 <Halcyon> Hehehe
59:04 <Nothing\> i remember i used to swim there all the time as a pre-teen with my friends. It was like our hang out spot. We'd all get together and go swimming cuz it was only like $2 and they had 3 olympic sized pools. Though the deep one was reserved for diving.
59:13 <Nothing\> good times
59:50 <Nothing\> and it was walking distance so we could go any time there was a free swim.
00:47 * Ampera hugs Nothing\ 
01:12 <Nothing\> lol it's funny, i can whistle with my fingers which is extremely loud. Like it's loud enough to deafen me partially for a good while if I go full out with no ear protection. But I used to whistle in the pool to screw with the life guards cuz they used whistles to indicate an emergency.
01:54 <Nothing\> I was a little shit so I didn't realize the severity of what I was doing. But the lifeguards swore up and down that we had a whistle. Despite us being practically naked
01:56 <Nothing\> also
02:06 * Nothing\ gives Ampera a good, tight hug <3
02:11 <Nothing\> how ya doing buddy?
02:12 <Ampera> how are you doing Nothing\
02:18 <Ampera> I'm alright, about to go to bed probably
02:21 <Nothing\> i'm doing pretty good
02:29 <Nothing\> yeah? it's a bit early for me
02:39 <Ampera> well I have work tomorrow
02:52 <Nothing\> i try to keep to a "normal" sleep pattern but i always settle on going to bed around 6am and waking up around 3 or 4pm
03:10 <Nothing\> no matter how hard I try, I just can't stick to any other sleeping pattern.
03:27 <Nothing\> maybe within a couple of hours of that at most, but that's it.
03:51 <Nothing\> that's good you can sleep good hours for work.
04:25 <Nothing\> I always had trouble. Especially for school, which is one reason why I dropped out. I was only getting a couple of hours of sleep per night.
05:12 <Nothing\> the worst is when you're lying in bed and can't sleep and all you can think is "if I fall asleep right now I'll get X hours of sleep"
06:27 <Nothing\> i'm lucky, i seemed to have outgrown my insomnia some time in my 20s
07:19 <Nothing\> i found a medication that worked wonders for it and took that for 10 years and when I finally stopped taking it, my insomnia was gone for good and I didn't need anything anymore. Unless that was from being addicted to opioids.
08:18 <Nothing\> cuz I had the same thing happen with my gimpy knees. I've had knee pain off and on since I was a kid, but ever since I got addicted to opiates it's gone away. But man does it ever come back when I don't have them.
09:16 <Nothing\> insomnia's horrible though. Especially if you have obligations.
09:34 <Nothing\> Just knowing you have to get up for something can be enough to keep you up all night.
12:52 <Halcyon> I usually can't sleep the first night before work
13:02 <Halcyon> My brain goes through all the things I need to do and how I'm going to do them
18:12 <Halcyon> Ampera
18:20 <Halcyon> I bought 12.5 kg of rye flour
18:45 <Ampera> I had no idea how much that is
18:48 <Ampera> *have
19:05 <Ampera> can I have that in improper units?
19:07 <Halcyon> 27.5 pounds
19:37 <Ampera> are you planning on baking a rather disgusting cake?
19:55 <Halcyon> No, I have heaps of sourdough starter
19:59 <Halcyon> Going to make bread
20:16 <Halcyon> I made some out of spelt flour the other day, turned out nice. But I prefer rye
20:29 <Ampera> so why do you need 38.19 dollars of rye flour for that
20:42 <Halcyon> So I can make many loaves
20:47 <Halcyon> But also I'm giving some to next door
20:56 <Ampera> It's gonna go straight to your hips!
21:04 <Ampera> right next to all the other things that have gone straight to your hips
21:09 <Ampera> and really the rest of your body
22:22 <Halcyon> *shrug*
22:46 <Halcyon> We made really nice pizza dough from the same sourdough the other day
22:49 <Halcyon> It was SO good

00:34 <steve30> Halcyon, we were teaching Ampera about cum in the other channel earlier :p
02:42 <EEVBot> [Twitter] - eevblog - RT @TubeTimeUS: clear/transparent chip packages seem to be trendy, so let's look at a few from my collection. 🧵 https://t.co/4NaJg6sv6X
50:23 <Nothing\> lol steve30
50:39 <Nothing\> i knew somebody who had an actual recipe for fake cum for some reason
50:55 <Nothing\> well, he was bi so i'm sure i could imagine why he would make it
56:52 <Halcyon> steve30, oh?
57:04 <steve30> hehe
57:20 <Halcyon> What about it?
58:33 <steve30> About how its a latin word for 'with'. He thought it was something else :p
58:45 <Halcyon> :P
00:43 <Halcyon> They are going to put exemptions on restrictions here for those who have had both vaccinations. Finally some common sense.
02:09 <MrMobodies> Hello
02:17 <Halcyon> Hey MrMobodies
02:40 <steve30> How about they get over themselves and just remove restrictions altogether?
03:01 <Halcyon> steve30, because only ~15% of the population have had both shots
03:24 <Halcyon> If we lifted restrictions now, they'd lose control like what happened over there and in the US
03:33 <Halcyon> The US did the right thing and really stepped up vaccinations.
03:51 <MrMobodies> that is frightening about the bloodclots
04:04 <Halcyon> You have a higher chance of being killed by a passing bus
04:13 <MrMobodies> I read one news reporter died but the rest of the family where okay
04:14 <Halcyon> Or dying from literally walking down the street
04:51 <MrMobodies> now that was a risk in my previous area
04:53 <Halcyon> You're talking maybe 4 in 1 million people.
05:38 <MrMobodies> in another 10 years I'd trust it when I know everything about it... if I am still alive.
06:10 <MrMobodies> but that's just my paranoria
06:10 <Halcyon> Every vaccine has risks, albeit small. COVID-19 is no different
06:22 <Halcyon> People line up every year to get their flu shots
06:30 <MrMobodies> in 1994 at a primary school I had a vaccine for something there
06:47 <MrMobodies> and I didn't feel right for over 2 years
06:56 <steve30> Halcyon, they did drive-thru' flu jabs here this [last] year
07:05 <Halcyon> Yeh they do it here too Steve
07:21 <MrMobodies> I felt it changed me in some way like I felt horrible like the symptoms of a cod
07:29 <Halcyon> But some people are stubborn and are either holding off for whatever reason, or they "want" the Pfizer jab
07:29 <MrMobodies> but it went away in 1997 I think
07:42 * T3sl4 jabs Halcyon with his little prick
07:49 <Halcyon> Pointy
08:14 <Halcyon> But yeh, I think if they exempt people who have had their shots from certain restrictions, it will bring more people forward to get theirs.
08:26 <Halcyon> Vaccination isn't just about the individual, it's about the community as a whole.
09:19 <Halcyon> MrMobodies, probably measles/rubella?
09:23 <T3sl4> speaking of stepping up, my canadian friend got his 2nd pfizer as of yesterday
09:29 <MrMobodies> aaah measeles
09:53 <MrMobodies> I felt alright after the injection but about 6 hours later I felt cold symptoms
09:55 <Halcyon> Kids here are vaccinated for free against these: https://www.health.nsw.gov.au/immunisation/Pages/schoolvaccination.aspx
09:57 <EEVBot> [Title] -
10:03 <MrMobodies> and had this horrible sensation for many years
10:09 <Halcyon> MrMobodies, that's a common immune response.
10:20 <MrMobodies> it around my stomache
10:26 <Halcyon> Many people feel ill for 24-48 hours after vaccines.
10:26 <MrMobodies> and I felt poorly
10:39 <T3sl4> i forget what the traditional types (MMR etc) are. attenuated, killed?
10:41 <MrMobodies> but it should last for over 2 years
10:48 <MrMobodies> I mean the sensations
10:54 <Halcyon> Yeh dunno
10:59 <steve30> Here, the majority of the country have had covid vaccines, and now they are complaining that not enough people are having vaccines. Well, that's because most have had it!
11:11 <Halcyon> How many is "majority" Steve?
11:25 <T3sl4> the ones more directly based on the things they protect against, have a variable chance of mutating to their original thing, and that can cause bad reactions
11:28 <MrMobodies> one of my cusions in the states is having vision problems
11:35 <MrMobodies> after taking one.. I don't know what one they took
11:37 <Halcyon> Looks like about 57% of the UK have had both
11:42 <MrMobodies> so I am awaiting for them to call back
11:51 <steve30> I think about 70% ish have had at least one. Maybe 80%.
11:51 <Halcyon> It's still not enough. You want herd immunity. You won't get that until you get up to 80%
11:59 <T3sl4> nice thing about the covid vaccines, well the moderna and like, they have exactly zero original material in them, and such a reaction is completely impossible
12:25 <MrMobodies> I see so they just trick and auto immune response
12:32 <MrMobodies> so anti bodies can be made quicker
12:35 <Halcyon> Yep, that's what vaccines do
12:52 <rust_collector> I like how I do not have to grab my fork, I can just get close, and it jumps into my hand
12:56 <MrMobodies> whereas the Aastrazenica is based on the flue vaccines with particles of the virus in there
12:58 <Halcyon> Which is why you feel sick. It's not due to the virus itself. It's because of your own body's response to a foreign entity.
13:18 <T3sl4> after my 2nd shot i felt the usual full gamut of an immune response, the headache, malaise, soreness etc, but what's weird is there was no runny nose or sore throat or cough or any of that to go with it
13:26 <T3sl4> which is exactly what it's supposed to be :)
13:30 <Halcyon> It doesn't matter which brand you get, some people still feel sick for a day or so
13:35 <Halcyon> It's just the normal way of things
14:12 <T3sl4> a strong immune reaction is like a strong police reaction. they beat up innocent bystanders, and the whole society is hurt somewhat as a result
14:14 <Halcyon> But I have to say, my 5G reception is pretty awesome
14:18 <T3sl4> ...what, too political? :P
14:20 <Halcyon> I'm very happy with mine
14:59 <T3sl4> or rather, they beat up bystanders /too/, as in cross fire :P
15:16 <MrMobodies> can't get a good 3g signal in this village
15:30 <MrMobodies> no 4g or 5g
15:44 <rust_collector> I can not get a 3g signal at all, because they no longer use that here
16:08 <steve30> Halcyon, did I tell you I got a Fruity phone yesterday?
16:25 <Halcyon> I think we still have 3G on 850 MHz, but most of the others have been shut down in favour of LTE/5G
16:31 <Halcyon> Fruity phone?
16:54 <steve30> iPhone 5S
17:11 <Halcyon> What did you have before?
17:43 <steve30> My main mobile is a Nokia 6510. I can safely say the iPhone will /not/ replace it :)
18:09 <Halcyon> Good boy
18:42 <steve30> I would never buy an iTrackingdevice *ahem* Phone, but someone who upgraded was going to throw it out, so gave it to me instead.
19:04 <steve30> I'm going to see if I can get a SIP client running on it
19:05 <MrMobodies> I've got a Nokia E72 thinking of getting another battery
19:09 <MrMobodies> and just using it for the bank stuff
19:27 <MrMobodies> it's so old I don't see a danger yet
19:37 <MrMobodies> it only takes an "app" somewhere
19:43 <MrMobodies> on android
20:13 <MrMobodies> any phones given to me I wouldn't use them for anything serious
20:32 <Halcyon> Likewise, I never throw any of my old phones out, I have a whole box of them
20:37 <MrMobodies> I have only yesterday turned off more Firefox 68 things
20:46 <Halcyon> If I must destroy them, they go through the crusher at work
20:46 <MrMobodies> Android Firefox I mean
20:59 <MrMobodies> that's handyhaving a crusher
21:10 <MrMobodies> can it crush humans in whole?
21:28 <MrMobodies> or is it a small one?
21:32 <rust_collector> only small humans
21:55 Join: Guest69 ([email protected]) to #EEVblog
22:24 <Halcyon> MrMobodies, it can crush things like computers and hard drives and such
22:32 <Halcyon> It's about as tall as a person
23:50 <MrMobodies> I know someone who use to keep a draw of broken hard drives that came out of bank cctvs
23:59 <MrMobodies> waiting to be crushed
24:12 <MrMobodies> well some of them were fine and the cctvs stopped working
24:25 <MrMobodies> one day he couldn't find IDE drives that would work with them
24:38 <MrMobodies> so scavenged some of those that I tested out
24:49 <Halcyon> I love old drives
24:59 <MrMobodies> he ordered these Hitachi drives the same size and they just wouldn't detect them
25:00 <Halcyon> Which reminds me, I need to buy some SCSI to SD adapters
25:23 <MrMobodies> I have a few ide to SD
25:27 <MrMobodies> very handy
25:43 <MrMobodies> I think I sent Ampera sata to SD with a Toshiba flashair
25:54 <MrMobodies> all pre set to share the dos files through the wifi
26:03 <MrMobodies> or any image folders
26:23 <MrMobodies> the only thing is once accessing of a folder can't write to it remotely without resetting
27:35 <MrMobodies> someone is moving into their new house, they decided to get super fast fibre optic
28:09 <MrMobodies> it's £35.99 for 30mbps or £39.99 for 80mbps (80 is what they had in their previous address)
28:21 <MrMobodies> so she's going for for £35.99
28:37 <MrMobodies> for less than half of what she was getting
28:48 <MrMobodies> do you think that is penny wise poung foolish?
29:06 <MrMobodies> £4 to get the full 80mbps throughput
29:10 <rust_collector> depends of if she needs more speed or not?
29:23 <MrMobodies> She's going to be using it for Netflix
29:30 <MrMobodies> It's probably manage it okay
29:34 <rust_collector> if that runs ok on 30, then...
29:52 <MrMobodies> but she's staying here and both lines are over 70mbps
29:57 <steve30> is that actual fibre or just VDSL?
30:08 <MrMobodies> I suspect it is going to be VDSL
30:25 <MrMobodies> she said all the fancy bullshit terminology imaginable from her phone call
30:39 <Halcyon> I was going to say, 80Mbps isn't that much
30:43 <MrMobodies> ultra superfast powerfull you're not going to notice etc
31:01 <Ampera> I think it'll be a great day when I can be on the internet and not hear a damn word about vaccines or covid
31:03 <steve30> We have 40/10 VDSL and can manage multiple Youtube streams over an 802.11n connection so for video 30Mbps will probably be fine.
31:04 <MrMobodies> I was on that in my other area but I only got 60mbps
31:18 <MrMobodies> and that was 6 years ago
31:38 <rust_collector> I really like my fiber. but going from 80 to 500 did not change anything for me, other than downloading isos and such.
31:41 <MrMobodies> and I am stilling paying for 2x 80mbp lines
31:53 <MrMobodies> oh yes good for downloading files
32:03 <Ampera> We used to have 75/75 FttP before they upgraded us to 940/880
32:08 <steve30> We used to have 80/20. The difference is clearly measurable, but not that noticeable for most tasks.
32:21 <Halcyon> Even 2160P content on Youtube doesn't require huge amounts of bandwidth
32:26 <Halcyon> I'ts pretty compressed
32:37 <rust_collector> but the complaints from the kids playing games and stuff has stopped, so there is that
32:41 <steve30> Ampera, I gather there is a big industry built around the anti-vaccine movement, so it'll probably be around for a long time to come.
32:41 <MrMobodies> Steve30 what do you have now?
32:59 <steve30> 40/10
33:21 <Ampera> It's especially noticeable when I want to download something off my servers elsewhere
33:32 <MrMobodies> I know Virginmedia are offering 300mbps in my area (not sure about the business subisdary) but I wouldn't want to go back to them ever again..
33:49 <Ampera> steve30, It's just a nonstop excuse to treat people like garbage.
34:24 <Ampera> To harass and abuse people with moral impunity is the sweetest of political fruits.
34:26 <MrMobodies> 40 up 10 down?
34:32 <steve30> MrMobodies, my Dad's area now has FTTP. He is still on rather slow ADSL so I might 'upgrade' him at some point if he fancies paying the extra.
34:41 <steve30> yes
34:41 <Halcyon> I'm on 100/40 on VDSL2, but they over-provision it slightly so the maximum realworld I can pull is about 104/42 Mbps
35:09 <Halcyon> I mean it's good enough for now until I get fibre
35:18 <MrMobodies> I never heards of that before with ADSL2
35:38 <MrMobodies> I know someone managed to get 20mbps when they switched from Namesco to BT 4 years ago (they didn't have FFTP)
35:38 <Ampera> I'd say 50/50 is the slowest a connection could go on either metric for me, as an individual, to still be content.
35:49 <Ampera> Any less and I consider it bad internet
35:51 <steve30> Mine is VDSL
36:19 <MrMobodies> modem?
36:22 <MrMobodies> or router
36:50 <Ampera> VDSL basically doesn't exist here outside of a few AT&T installs, since anyone in range for VDSL gets PON fiber that's cheaper in the long run.
37:01 <MrMobodies> I use the HG635 just for the modem in bridge modem (for the DSLSTATS monitoring) and let pfsense do the rest.
37:23 <Halcyon> That's why our government are now ripping up the old copper after 10 years, because, gees, who knew fibre was cheaper in the long run?
37:26 <Ampera> It amazes me how much cash gets shoved into DSL tech just so ISPs can avoid doing it right and just installing fiber
37:27 <Halcyon> Only anyone with half a brain
37:37 <steve30> Combined ISP supplied modem/router. We used to use an Openreach ECI modem but that's redundant now.
38:38 <MrMobodies> I know someone a month ago, their aluminium phone line finally broke after many years of misery. They were about to run copper but said, no there is a fibre infractsture in the greenbox and we'll run that instead
38:53 <MrMobodies> they also live in a village in the south east somewhere
39:13 <MrMobodies> from 4mbps to over 200mbps
39:17 <MrMobodies> fttp
39:27 <Ampera> I'd say the only promising FttN tech is DOCSIS based stuff
39:29 <MrMobodies> they're well pleased
39:48 <Ampera> at least if they can get DOCSIS anywhere near symmetrical like they're planning
39:49 <MrMobodies> aaah Virgin Media
40:13 <MrMobodies> they use Docsis but with Coax
40:24 <Ampera> Still not better than fiber, but best I know it goes farther and carries more than twisted pair
40:34 <Ampera> As opposed to what
40:45 <Ampera> DOCSIS but with wet string?
40:45 <Halcyon> Glass is the future
40:58 <Halcyon> We knew this long time ago
40:58 <Ampera> Halcyon you're starting to sound like google
41:01 <Ampera> glasshole
41:09 <Halcyon> It's just trying to convince the idiots with the money
41:27 <Ampera> you do that with underage sex, not logic
42:59 <MrMobodies> yesterday at the pub I lean't someone some stuff... to play around with.
43:08 <MrMobodies> they've got a problem
43:18 <MrMobodies> they have a house with a garage
43:43 <MrMobodies> they recently decorated it brough Sky with the box and they're not happy with the broadband
43:45 <steve30> I wonder if my Mum still thinks we have Fibre.
43:50 <MrMobodies> the router is in the garage far away
44:02 <MrMobodies> and it is a SR102 type notorious for poor signal
44:16 <Halcyon> steve30, your mum is probably just happy she has the "Youtubes" and the "Facebooks"
44:29 <MrMobodies> So well try this old Draytek 2830N for the wifi and a bridge
44:39 <MrMobodies> already joined to it and a switch for upstairs
44:50 <MrMobodies> not ideal though
45:09 <MrMobodies> talking of youtube I found two things today
46:44 <MrMobodies> type in Youtube: amytivvle
46:54 <MrMobodies> and see the first result on the top
47:11 <MrMobodies> then try searching for "shining"
47:23 <Halcyon> The buzzfeed one?
47:31 <Halcyon> I assume everyone's search results will be different
47:35 <MrMobodies> advertising me movies to rent or buy. I remember they were random at the bottom of the results
47:43 <MrMobodies> but they seem to be pinned at the top now
47:52 <Halcyon> Mine as spread throughout
47:54 <MrMobodies> so this sorts that out
47:56 <MrMobodies> youtube.com##.thumbnail-container.style-scope.ytd-movie-renderer
47:56 <MrMobodies> youtube.com##.text-wrapper.style-scope.ytd-movie-renderer
48:32 <MrMobodies> and then there 8 more... 2 more. When I search for something, I have to stop and click to see more
48:45 <MrMobodies> I see this happening last year on some websites
49:07 <MrMobodies> they'd fade the comments and I'd have to click something see the end but if I turned off javascript i see everything
49:18 <MrMobodies> I don't know what they're playing at
49:36 <MrMobodies> I started a thread on it

49:40 <Halcyon> I've been watching videos taken by tourists in North Korea
49:45 <MrMobodies> oh
49:58 <Halcyon> It's quite amazing the efforts NK go to to fake stuff, but no one buys any of it
50:04 <MrMobodies> nice up there?
50:12 <MrMobodies> oh fake stuff?
51:06 <Halcyon> Well the stuff tourists get to see, I mean are deliberately shown, is "nice" I guess? I mean it's as good as it's going to get in a country like that

35:49 <steve30> hi
35:56 <watcher> hi steve30
36:27 <steve30> Good to see that LBRY is doing well
36:52 <watcher> yes that makes it easyer to go of youtube
40:12 <steve30> I've been on LBRY a few months now. I haven't imported my entire youtube channel though, i've only been uploading the new videos.
43:09 <watcher> i watch only on LBRY/odysee and i like that there are caterogies. so i not need to subscribe to a channel to see the latest video. and it is small enough to watch the vids from the bigger channels
43:46 <watcher> i need to go now have a nice day? bye bye

17:44 <Halcyon> That's cool
26:45 <Nothing\> yay
27:35 <Nothing\> i can finally print out the manual for games like astra-256 and tis-100 where it has some assembly type language and being able to view documentation at the same time as programming is very helpful
28:01 <Nothing\> instead of having to constantly go back and forth, or hooking up a second monitor
28:14 <Nothing\> i've really missed having a printer
28:21 <Halcyon> Hahaha
28:29 <Halcyon> I'm glad you're enjoying it Nothing\
29:28 <Nothing\> i just wish i could go nuts with it and like print off the 120 or so datasheets i have for my stuff, plus the 100 or so app notes and all of my manuals and the books i like to read on the can like the art of electronics
29:49 <Nothing\> Halcyon, i'm loving it, just wary of ink considering how little i got out of my last cartridge
30:04 <Nothing\> i got an XL cartridge this time but who knows how many more pages that means
30:17 <Nothing\> could be an extra 100 could be twice as many who the hell knows
30:47 <Nothing\> given it costs twice as much i'd hope i'd get at least twice as many
31:08 <Nothing\> or just under that many, taking other costs of it into consideration
31:52 <Nothing\> damn mosquito bit my ankle. Why do they always go for the ankles and feet?
32:05 <Nothing\> or failing that, the legs
32:29 <Nothing\> oh shit
32:37 <Nothing\> i should put after bite on it
32:42 <Nothing\> i forgot i had that stuff
32:51 <Nothing\> it's just ammonia but damn does it work well

41:48 <Halcyon> Not too bad, you?
42:13 <doggyrat> i am good
42:29 <doggyrat> have you seen the video of my scope cam
43:44 <Halcyon> I have not
44:02 <doggyrat> wait i will send you the link by pm
45:45 <doggyrat> it needs to be adjusted and a bit modified but it works
46:51 <doggyrat> depending on the lens that is mounted on the cam the angle of view get more narrow and the pictures is bigger

28:53 <K> hm, how would NE5532 do as a differntial amplifier, given that resistors are hand matched to be reasonable?
29:10 <K> or should i look for something else
29:25 <T3sl4> for what?
29:41 <T3sl4> it's a standard audio sort of amp, relatively high input bias IIRC
30:06 <K> im still going on about my dac channel
30:52 <K> i generate signal two complementary r2r rails and then intend to diff those to reduce noise and unpleasantness
30:54 <DHess_US> By itself? Terrible.
31:04 <DHess_US> That is not a differential amplifier.
31:12 <K> thats what i thought yea
31:43 <DHess_US> That is either a difference or instrumentation amplifier. Differential amplifiers have differential inputs and outputs.
31:53 <T3sl4> well, operational amplifier
32:05 <T3sl4> but yeh diff or inst is a configuration of opamps
32:23 <K> um, i've gotten my names wrong, sorry about that
32:47 <DHess_US> Parts like the NE5532 are good as difference or instrumentation amplifiers when you need higher speed and lower noise.
33:04 <T3sl4> i don't think you're wrong, you noted that there's resistors around it, not an amp by itself :P
33:09 <DHess_US> But not necessarily the best DC precision.
33:35 <K> it is for audio, some dc offsets do not bother me that much,
33:37 <K> yet
33:40 <T3sl4> it does whatever it does, as long as you meet the CMR, input bias, don't expect more than input offset, etc.
33:55 <DHess_US> K, then that is a good choice.
34:17 <T3sl4> note that it's not RRIO so you'll need like +/-5V or more rails
34:30 <K> i have designed for +/-9
34:38 <T3sl4> alright
35:15 <K> some maxim charge pump doubler and lt regs to clean it up
36:02 <DHess_US> I've used difference amplifiers like that in audio amplifiers to good effect in the past.
36:14 <K> not completely sold on if i need the fancy lt regs or could do with something simpler
36:20 <K> ah. ok
36:59 <DHess_US> Even just using 1% resistors is good enough to provide significant common mode rejection.
37:21 <K> i intend to buy a roll and do sorting by hand
37:41 <K> well, not 1000 but like 100
37:48 <DHess_US> Usually doesn't matter because the AC common mode rejection will be trashed by the layout unless it is trimmed.
38:12 <K> hm, ok
38:19 <DHess_US> Or use 0.1% resistors which are still cheap.
38:23 <K> yeah
38:30 <K> i need 4 per channel for this
38:35 <K> not that expensive
39:06 <DHess_US> Like I said, it isn't usually critical. 1% gives like 55 dB rejection or better which is usually plenty.
40:01 <K> and this brings me to the other question - what do i need to measure the goodness of this all
40:17 <K> an lna and a scope?
40:41 <DHess_US> The common mode rejection and gain can be measured with an oscillator and AC voltmeter.
41:05 <DHess_US> LNA is only needed if you want to measure the noise, but if the noise is high, so what? It isn't like you can trim that out.
41:49 <K> i thought more about the output
44:21 <DHess_US> K, is this for an line level audio input?
45:09 <K> goal is to have output as line level
46:24 <DHess_US> Oh, how much gain?
46:28 <K> but i might have to do something to reduce the level, as r2r ladders produce up to 3.3V (approx) and after summing it is +/-3.3V
46:54 <DHess_US> Douglas Self used the NE5532 like you describe with 10k resistors for line level inputs.
47:01 <K> if i've not muddled up something terribly
50:28 <K> https://imgur.com/a/x2PS3c1
50:28 <EEVBot> [Title] - Imgur: The magic of the Internet
50:39 <K> the magic!
53:21 <DHess_US> Why paralleled input buffers?
55:50 <K> due to layout i did not want to pull r2r lines to one opamp
56:05 <K> so it was either leave one unused, or just put them together
56:32 <K> are there drawbacks for doing this?
56:59 <DHess_US> If you are going to do that, then do this instead, https://www.allaboutcircuits.com/technical-articles/learn-about-three-op-amp-instrumentation-amplifiers/
56:59 <EEVBot> [Title] - Please Wait... | Cloudflare
58:13 <K> oh
58:14 <K> thanks
58:22 <DHess_US> And then do this on the output to implement AC coupling, https://i.stack.imgur.com/NvnNy.png
00:32 <K> the op1177 part, right?
00:50 <K> hm
03:00 <K> ah got it
03:54 <K> that AD822 aint cheap though
04:01 <K> AD8220
25:03 <DHess_US> I don't mean use those parts.
25:28 <DHess_US> The AD8220 is the equivalent of the 3 op-amp instrumentation amplifier
26:30 <K> ah.
26:59 <K> this makes me wonder do i even need the sample-and-hold part
28:08 <DHess_US> I'm not convinced you even need the difference or instrumentation amplifier.
30:18 Join: modrobert ([email protected]) to #EEVblog
32:16 <K> well, the r2r is driven by a mcu, so i think the end result there will have some extra (not random) noise
32:54 <K> diff would help to reduce that (2 complementary r2r "rails")
