18:06 * Ampera hugs electrohead 
18:27 <electrohead> I fucked my knee up really bad last night, horsing around with a friend
18:37 <electrohead> he came down on my knee really weird, now it's completely fucked
18:47 <Ampera> that's fucked
18:57 <electrohead> waiting on the phone call back from urgent care, yay
19:34 <Ampera> that sucks
19:44 <Ampera> I have a 4 day weekend though
19:58 <electrohead> that's good
20:04 <electrohead> my weekend got ruined, lol

48:44 <jaymax> I was peak gamer in the days of GTA I
50:09 <arch> boss was kind to give us a half day. monday is off. so i do believe i can get that off-line, topswitch flyback built over the weekend @T3sl4
50:53 * flyback bites arch
51:22 <arch> :3 now you know what i feel when the hippies are talking about Arch Linux all day
51:47 <K> haha
51:59 <arch> speaking of which...that's how i got my username: from the default username i used, back when i used to run Arch Linux
52:25 <jaymax> Just do what Nothing\ does
52:53 <arch> i have that guy on my ignore list, cuz he just goes off topic so many times and says so many foul things
53:10 <jaymax> Well, not that.
53:22 <jaymax> go arch\
53:38 <arch> ahh, good idea. but then i would have to register that nick. can't be assed
55:04 <jaymax> OFC, if taking the effort, go the step further - like arch👆
56:16 <jaymax> I haven't been assed to register my nick - nor did the guy who used it before this week.
56:21 <arch> if you use Arch Linux after you're like...22 or 23...you're way past your rebellious years--i recommend settling down with Debian or Fedora. no broken system every 2 weeks from upgrades
57:20 <jaymax> But my switching to Debian *was in* my rebellious years. Does this mean I must settle down to Slackware?
57:29 <Erhard> LOL
58:10 <arch> lol jaymax
58:13 <jaymax> I'm damn-near 40 - I've been using Debian since 1999!
58:30 <Erhard> Kali->Arch->Slack->Debian->Ubuntu->Alpine->OpenBSD->NetBSD->FreeBSD
58:57 <arch> does that mean the BSDs are the least favorable or most favorable to you Erhard
59:08 <Erhard> Most, course ;-)
59:17 <jaymax> I guess this is in no particular order Erhard
59:29 <Erhard> That would be the order you would go from young to old
59:38 <Erhard> I actually went:
00:17 <Erhard> NetBSD->RedHat(free-precommercial)->Debian->Ubuntu->OpenBSD->FreeBSD
00:27 <Erhard> For actual main use OSes
00:33 <Erhard> NetBSD in the mid 90s
00:37 <jaymax> I'm perplexed how the FreeBSD compromise would be at the very end. Unless the neckbeard got too long while on OpenBSD and needed to pull back.
00:53 <Sigyn> When I first started I'd just go with whatever was on the disk with whatever linux magazine I bought from the bookstore.
00:58 <Erhard> OpenBSD is a headache to actually run.
00:59 <arch> for me it was, in order of distro hopping: ubuntu > mint > debian > arch > fedora. there was a particularly rebellious stage where i even used SliTaz, but that was due to really shitty PC specs.
01:23 <Erhard> Things are updated very slowly.
01:29 <jaymax> Yeah that's my assessment of OpenBSD.
01:48 <Erhard> It has some great stuff, don't get me wrong. But in production? That is tough.
02:23 <Erhard> Is fedora basically like the original RedHat when it was free and non-commercial?
02:27 <jaymax> I didn't even find FreeBSD 12.x good enough for production.
02:35 <Erhard> I just put Alpine on a vm.
02:39 <Erhard> jaymax: How so?
02:41 <arch> Fedora is RedHat8 packages beta testers
02:48 <Erhard> Ha!
03:17 <arch> i have never had Fedora crash after any system upgrades though, unlike Arch Linux. so that's good
03:49 <jaymax> DBus gaps preventing hotplugging, hibernation, etc unless you spent a serioul amount of time to track down what's going on.
03:52 <Erhard> In all honesty, as much as I prefer BSD, linux is the best supported for real production. They have all the $$
03:56 <arch> i can't ever recall Ubuntu, Mint, Debian, or Fedora crashing the system after a full system upgrade
04:16 <Erhard> jaymax: I see. I don't use any of these as a desktop. I mean for server production
04:46 <Erhard> I had one Ubuntu 18 vm get crazy corrupted. It was being run as a desktop (VirtualBOx).
04:51 <jaymax> Yeah. My only misery with Linux is with NVIDIA and I cannot even blame Linux for that.
04:53 <Erhard> No diea what happened to it. It was a mess.
05:15 <Erhard> The thing is they NEED nVidia.
05:31 <Erhard> If these things want to really be great desktop platforms you need awesome graphics drivers.
05:42 <Erhard> This is where WIndow soutshines everything, including Macs by a long shot.
05:49 <Erhard> Windows outshines
06:22 <Erhard> I would prefer everything be open source, but I can put up with a closed source graphics driver if it is good.
06:28 <jaymax> Yet, NVIDIA stopped the Nouveau contributions bcos muh proprietary.
07:49 <Erhard> I may be too old, is bcos because?
08:16 <arch> yee
08:17 <Erhard> I am not saying I love them as a company, but I wish we had great drivers.
08:18 <jaymax> And their closed-source updates caused multiple problems for me in the past, failing to start Xorg (at a time when I had the intel iGPU conflict so console mode was dead too).
08:21 <Erhard> IN every FOSS
08:33 <Erhard> Huh. That sucks
09:09 <jaymax> So if there was a stuck fsck or Xorg failed, I'd need to ssh in to determine which it was.
09:21 <Erhard> Better than serial console ;-)
09:28 <jaymax> if stuck fsck, I wasn't getting in.
09:35 <Erhard> Yeah.
09:45 <jaymax> Reboot and pray, or live image.
09:52 <Erhard> I am liking vms more and mroe becaus eyou get the remote serial or vnc console easily if there is an issue
09:56 <Erhard> And you can snapshot, etc.
10:11 Quit: Kuschelpony ([email protected]) Ping timeout: 121 seconds
11:25 <jaymax> Yeah I should shove a basic GPU in my basement server for passthough in lxc - since I `ssh -X` to a container often.
12:48 <Erhard> With remote X doesn't the client GPU do all the work?
13:11 <jaymax> It does? oh nvm then.
13:23 <Erhard> I don't know. I htink it does most of it.
13:48 <jaymax> I used to use x2go and the lag was similar - granted my client is a RPI4.

14:05 <Erhard> I am compiling the entire freebsd OS on a RPI-B
14:12 <Erhard> 256M of RAM
14:22 <Erhard> Still going after 4-ish days
14:26 <Erhard> I need to cross compile
14:28 <Erhard> ;-)
14:45 <jaymax> Yeah guess so. LOL
15:08 <Erhard> I make a vm to do the cross in I guess.
15:26 <Erhard> Just cleaner that way, runing all that stuff as root.
15:40 <jaymax> The model B is essentially a downsized Zero now right?
16:39 <Erhard> I think so. It was the first one released
16:44 <Erhard> The A came after

16:48 <Erhard> arm6
17:39 <jaymax> They still do the B vs A - as form factors.
17:41 <Erhard> At first I had it using a thumbdrive as swap and the /usr/src /usr/obj
17:59 <Erhard> Then I got it on a USB rust drive. Still slow as snot
18:04 <Erhard> Does some thrashing here and there.

18:29 <Erhard> I thought it would be faster, and it was for a while, but now it is on some bigger binaries and they are using more RAM.
18:43 <jaymax> arm6 seems like it didn't get used by them again. IIRC it's v7l or higher.
18:45 <Erhard> So doing some vm thrashing to swap
19:02 <Erhard> I think so. arm64 is the way to go anyway.
19:08 <jaymax> Yup
19:14 <Erhard> I just wanted to use this as a small nameserver.
19:21 <Erhard> And it's fun to mess with.
25:16 <jaymax> I have a few of those Soekris net4511 boxes (AMD Elan 133MHz - 80486+ instruction set) and it's something I want to mess with. Particularly, if Desqview/X (supports ssh) would function without a graphics card.
26:17 <jaymax> It'd make a neat WFW3.11 box to remote into
26:47 <DHess_US> I've been really happy with my apu4d4, https://pcengines.ch/apu2.htm
26:48 <EEVBot> [Title] - PC Engines apu2 system boards
33:38 <Erhard> Yeah, those PCEngines are nice
35:01 <Erhard> I would like to make something like this: https://www.youtube.com/watch?v=CyEpshm16HY&t=274s
35:02 <EEVBot> [Title] - Youtube: Manage ANY PC or Server Remotely! - TinyPilot KVM over IP
35:16 <Erhard> YOu can build yourself for less.
35:51 <Erhard> I'd really like some way to hook up a BUNCH of servers to some sort of remote KVM (at least 4, ideally 8-16)
36:47 <jaymax> Yeah I heard about those.
37:16 <jaymax> Compelling for other reasons around here.
42:19 <DHess_US> Of course a server farm of Raspberry PIs also works, and there is a lot of infrastructure support for it.
42:25 <Erhard> It's a little more than I want to spend on somehting that just saves me having to walk either in the machine room or in the remote machine room and hook up a monitor.
42:30 <DHess_US> But the APU2 is x86
43:06 <DHess_US> Lol, can tell my workstation finished processing because the fans slow down.
43:08 <Erhard> Yeah, I have so much x86_64 HW since commercially I have a 45 node render farm of high end gear.
43:42 <Erhard> So I end up with a bunch of machines a few years old that are no longer viable versus the lastest top of the line gear, but are still great servers.
44:29 <arch> looks good? https://i.imgur.com/1GqKtxs.png
45:54 <T3sl4> arch: no. you made 4-way junctions
46:11 <arch> whats that mean
47:04 <DHess_US> I don't see anything obviously wrong, but why so much output capacitance?
47:19 <DHess_US> To suppress 120 Hz ripple?
47:28 <DHess_US> The input capacitance is awfully low.
47:29 <arch> 10uF is too much?
47:36 <arch> oo u talkinga bout the 1000uF x2
47:38 <DHess_US> Um, *output* capacitance3
47:39 <Erhard> Wouldn't the ripple be at the switching freq?
47:56 <DHess_US> Erhard, not if the input voltage falls far enough.
48:10 <Erhard> Interesting
48:29 <arch> well, in the appnote for the topswitch, they only used 6.6uF input cap for a 10W output. fsw is 130kHz
48:30 <Erhard> So 120Hz riding on the swithcing freq
48:39 <Kuschelpony> arch, that looks not fundamentally wrong for me, so i think you should do it
48:58 <T3sl4> arch, https://electronics.stackexchange.com/questions/28251/rules-and-guidelines-for-drawing-good-schematics #11
49:00 <EEVBot> [Title] - standard - Rules and guidelines for drawing good schematics - Electrical Engineering Stack Exchange
49:16 <Erhard> Heh.
49:25 <T3sl4> 1.5KExx likely won't be needed, and you might want to check the datasheet on that MRA thingy
49:48 <Kuschelpony> the only thing that i would add as my personal opinion is an differentiel choke of some mH in series to the AC line to limit recharging spikes to improve powerfactor
50:13 <arch> MRA4007 is the surface mount version (SMA) of the 1n4007 thru hole 1A gen purpose diodes
50:49 <arch> are ya saying my schematic looks like garbage? =( i thought it looks pretty clean
51:21 <T3sl4> it is, with those three exceptions :P
51:26 <DHess_US> Hmm, input ripple of 34 volts which I guess is acceptable.
51:42 <DHess_US> Which makes sense if you were designing for 10% ripple on a 240VAC input
52:14 <DHess_US> I'd be really careful about the ripple current rating of C?
52:24 <DHess_US> And it still seems like you have way too much output capacitance.
52:28 <arch> ah i ahvent populated the designators
52:28 <Kuschelpony> arch, for me your schematic looks almost totally fine, except for the ground triangle poking up from the output minus
52:54 <arch> Kuschelpony, that is because kicad doesn't have a trafo with phases that are opposite, so i drew it like that
53:17 <arch> if i wanted the dot to be on the bottom side (i.e. flip the secondary), i would have to edit the symbol. that's annoying
53:18 <Kuschelpony> what i love is how you drawed the secondary as actual circuit with both wires to show the path you force the ripple into the capacitors, nut just everything in undefined way connedted to "ground"
53:32 <T3sl4> C? is probably too large also
53:44 <Kuschelpony> mmh, i should use Kicad schematics again after years
53:47 <arch> please hold..let me put designators so i can tell which C? you're taking about :p
54:16 <arch> https://i.imgur.com/61RubCA.png
54:20 <arch> there we go
54:43 <Erhard> But it would be more fun to switch random C?s
54:57 <arch> engineer roulette
55:13 <DHess_US> Ok, I'd take a very close look at the ripple current rating of C6.
55:15 <T3sl4> D4-D7 are fine, but what about D2
55:28 <T3sl4> C4 is probably too large
55:37 <Erhard> C7 and C9 should have adjacent numbers. It bother me that they are separated by 1 ;-)
56:00 <arch> -_-
56:08 <T3sl4> also, who the hell has 9.6k's? 220k || 10k is probably easier tbh, assuming you absolutely must have that extra 0.1V
56:10 <arch> that is kicad ordering scheme, you can set it by vertically or horizontally
56:26 <Erhard> I fugred.
56:29 <Erhard> figured even
56:30 <arch> bruh, 9.6k is a standard value resistor
56:30 <T3sl4> ah, it's reverse chinese ordering. bizarre
56:52 <T3sl4> i said who
56:52 <arch> i used those lower values to skip putting a load resistor
57:01 <T3sl4> i sure as hell don't stock em ;)
57:06 <arch> thats cuz ur a noob
57:13 <T3sl4> [X] Doubt
57:18 <arch> :D
57:33 * Erhard takes away all arch's 9.6k resistors.
57:51 <arch> hmm, for D2, they recommended a glass passivated (fast version) of the 1n4007, which i dont have unfortunately
57:58 <Erhard> I do find with most parts the round numbers are cheaper do to volume I guess
58:12 <Erhard> s/do/due/
58:26 <T3sl4> they're idiots. fast recovery UF4007 etc is fine
58:48 <DHess_US> It needs to be fast recovery if continuous conduction mode is possible.
59:20 <DHess_US> I guess it wouldn't matter on a forward converter because then CCM can't happen.
59:22 <arch> it will operate in CCM yes
59:41 <arch> you can operate forward conv in CCM tho
00:18 <DHess_US> Can the transformer core reset in CCM? I guess it can.
00:25 <DHess_US> I've never designed a forward converter.
00:31 <T3sl4> it's flyback tho
00:32 <DHess_US> They always seemed weird to me.
01:08 <arch> you seem weird to me :D
02:36 <arch> actually, i have the MUR160. that should do the trick. 600V pp rating
03:21 <T3sl4> pp hard
03:41 <arch> ppbus
07:18 <arch> "Sort of related, try to keep junctions to Ts, not 4-way crosses. This isn't as hard a rule, but stuff happens." but ok, let me rearrange this to make it neater
07:38 <arch> oh, let me show you what my noob days schematics used to look like
09:49 <Kuschelpony> dhess, in a forward converter, CCM is refering to the output inductor, not the transformer
10:17 <arch> https://imgur.com/a/eTn816f
10:18 <EEVBot> [Title] - Imgur: The magic of the Internet
10:50 <arch> thats one of the earliest kicad schematics i made, i think it's gotta be my second one
11:07 <arch> as you can see, it is pretty ugly
11:30 <arch> and i used the wrong symbol for switch :D
12:50 <DHess_US> the reason for that is that crosses are ground loops, and Ts are not, but in most cases it doesn't matter.
13:10 <DHess_US> Kuschelpony, yea, I just had to think about it more.
13:31 <DHess_US> I've studied them but never had a need to design one so they aren't familiar.
16:13 Quit: TheDude ([email protected]) Ping timeout: 121 seconds
17:24 <Kuschelpony> never studied anything of this
18:08 <Kuschelpony> its the kind of things i think about when i sit my daily hours in the trains and busses, taking my notebook and some pens and draw schematics to understand them
18:20 <arch> kudos
18:32 <arch> better than looking at memes or tiktok vids :D
18:55 <Kuschelpony> so basically i never learned any of the topologies, just invented them independly on my own
19:30 <Kuschelpony> also fully understood magnetic cirsuits, coil and transformer calculations (for not too high frequencies)
20:26 <Kuschelpony> the only thing i really cant remember is µ0
21:14 <DHess_US> https://i.imgflip.com/5lsihs.jpg
22:06 <arch> lol
22:10 <Kuschelpony> sorry i dont have the wrong brain for that kind of humor, but thanks for posting it
22:24 <Kuschelpony> sorry i DO have the wrong brain for that kind of humor, but thanks for posting it
25:45 <arch> alrighty, now we are ready. time to do the layout, then i make this over tomorrow and Sunday: https://i.imgur.com/osrrqRe.png
26:41 <arch> got all the parts i need, except tht TVS diode. which i think i will just skip
27:01 <arch> dont care if a surge burns out a tny. can get em for a dime a dozen
30:46 <Kuschelpony> just swimming in nostalgia, a few months and then i am online-adult
31:11 <Kuschelpony> the oldest Forum i still use, i registered in 2004
31:14 <arch> T3sl4, i have a fbt here with 4 windings. to find out the primary leakage inductance, i short the secondary and measure the primary winding. so far so good. but what if i have multiple secondaries? i noticed that, if i shorted out the first secondary output, the leakage inductance is 55uH; if i short out the second secondary winding, i instead see 68uH leakage. do i calculate the snubber values using the WORST leakage inductance value seen?
31:46 <T3sl4> how its used
32:02 <T3sl4> if you're not using aux then dont short it for the test
32:55 <Kuschelpony> arch, short the secondaries that you likely take the major current, keep the seondaries open that you likely dont use or only light loaded
32:56 <arch> what if i'm using all windings? do i short each of secondary windings one by one, measure the primary leakage, and pick the highest leakage inductance seen?
33:06 <arch> ooh Kuschelpony
33:31 <Kuschelpony> no, i would short all in paralell WHEN you can say for sure that you load all in use
33:44 <arch> ahhh
33:44 <T3sl4> then short the ones you use
33:52 <Kuschelpony> or when you are sure you dont use one full oaded then let it open for measuring
34:09 <Kuschelpony> you should imagine it that way:
34:48 <T3sl4> the point is, whichever winding is being switched, is shorted for that duration
34:49 <Kuschelpony> think you have a perfect transformer, and the stray inductivity is individually in series to each output
35:06 <T3sl4> so the primary is shorted, and all the other windings do their own thing
35:08 <Kuschelpony> thats not correct but a good approximation
35:19 <T3sl4> then the secondary(ies) are shorted and the primary and others do their own thing
37:25 <arch> i see. so just imagine that, if we have multiple taps being used, we are adding together the lekage inductance, per coil, in series with the actual inductance of the primary coil. so in other words, my primary coil measures 1.6mH with all the other windings open. but when i short the secondary, i see 55uH. therefore, the switching transistor is switching the 1.6uH PLUS the 55uH leakage inductance which is in series
38:06 <Kuschelpony> no
38:20 <Kuschelpony> it sees 1,6mH // 55uH when shorted
38:31 <Kuschelpony> or 1,6mH when open
38:59 <Kuschelpony> think about, the primary inductivity is the inductivity that is used to charge the core with magnetic energy
39:22 <Kuschelpony> the stray flux is what does not couple to the secondary but instead jumps back to the primary
39:44 <arch> im with you so far
42:10 <arch> to keep things simple for the first few times messing with topswitches, im just gonna use 1 primary, 1 secondary. even though the core i have here came from a topswitch with 4 windings. 250mW waste of energy this way, but whatever.
44:19 <T3sl4> can always parallel up any with the same turns
45:20 * Ampera winds T3sl4 up
45:37 * T3sl4 coils Ampera
45:43 <arch> im using the TNY267, which has a peak current lim of between 419mA and 481mA. i figured out the turns ratio with LCR meter and calculator; and i used my 555 timer saturation tester to find out the saturation on the primary coil (seems to be about 0.55A or so): https://i.imgur.com/PQTqsqm.png
46:34 <arch> the core is a E18 or E20
47:51 <Kuschelpony> i do not have the forumla here this moment, but you can calculate saturation from inductivity and core area, the number of turns and air gap length cancel out
48:20 <Kuschelpony> so you need just to enter xyz mm² and abc mH to get 0,28T
48:41 <arch> i cannot find out the number of turns i think, unless i strip off the tape to make room to put through a few turns of awg32 wire and measure the A_L
49:02 <Kuschelpony> not needed
49:30 <Kuschelpony> Al also falls out of that calculation
49:44 <Kuschelpony> i need to go through the past 10 notebooks, somewhere i have a few sheets of that stuff
50:05 <arch> hmm, how else can you get number of turns for a random core that is taped up?
51:01 <arch> L = N^2 * AL, is what i know of, so i usually scrape off the tape from the side, then slide in a few turns of really thin wire and measure the AL and L; that lets me approximate the number of turns
51:12 <Kuschelpony> arch, thats right
51:24 <Kuschelpony> what i wrote is only for the saturation calculation
51:38 <Kuschelpony> it took a few train trips until i had worked out that stuff
52:37 <Kuschelpony> its like that the increasing number of turns exactly cancels out the increasing length of airgap when you wind fro the same inductivity
54:45 <arch> yea. you know what, let me do that, very carefully. i will scrape some tape off the side and slide in 10 turns of awg32 magnet wire, and find out the AL value. that will allow me to approximate the number of turns, which should then allow me to calculate saturation flux density since i know the core size (or i can use my caliper to double check)
55:51 <Kuschelpony> you can also calculate in the other way if you have the number of turns
56:18 <arch> what do you mean by "in the other way"?
56:28 <Kuschelpony> B (in Tesla) = U (in Volts) * t (seconds) / A (core area * number of turns)
56:36 <Kuschelpony> the transformer forumla
56:49 <Kuschelpony> htere are two ways to calculate flux density
57:02 <Kuschelpony> the one is voltage multiplied with time divided by area
57:04 <arch> AHH, that actually might be way easier for me, because you see, what i found was, i was able to apply 11V for 120us before saturation
57:21 <Kuschelpony> the other is current multiplied by turns divided by airgap length
57:27 <Kuschelpony> RIGHT!!!
57:29 <arch> i used this method: https://moltensolderlabs.com/projects/555_timer_inductor_saturation_tester
57:30 <EEVBot> [Title] - 555 Timer Inductor Saturation Tester | Molten Solder Labs
57:54 <Kuschelpony> when you go over the voltage, the Al and air gap and all that just falls out, thats how you calculate mains transformers
58:48 <Kuschelpony> so 11V * 120µseconds / (xyz turns * abd core area)
59:20 <arch> excellent.. that helps a lot, thanks Kuschelpony for that formula. that's another to memorize
59:33 <Kuschelpony> hats why i love SI units
00:17 <Kuschelpony> not specifically because they are "metric" but much more because they are coherent that means everything is connected by a simple factor of 1
00:45 <T3sl4> you can rub together almost any combination of units, and represent something physically relevant, give or take a geometric constant or something
01:24 <Kuschelpony> even kw/h makes sense in some way :)
02:36 <arch> holy cow, they really used up every last inch of this core. i cant even pass through a single strand of awg32 wire in between the tape and the walls of the core
02:50 * T3sl4 varnishes arch
03:04 <arch> oh, guess they must have used varnish then
07:12 <arch> Kuschelpony, for that formula, the area is in meters or centimeters?
07:44 <arch> if centimeters, you get Gauss instead of Teslas right? or maybe im thinking of something else
11:54 <Kuschelpony> im not familiar with gauss
11:58 <Kuschelpony> its im meters
12:15 <Kuschelpony> or to be exyactly square meters
12:29 <Kuschelpony> when you enter square meters, volts and seconds, you get teslas
12:43 <Kuschelpony> https://upload.yax.im/upload/fEYeN145iWRSQDKQ/HV-Trafo.JPG
12:53 <Kuschelpony> have not yet drowned that i wax
13:54 <arch> what is the purpose of putting gaps in between turns?
14:24 <Kuschelpony> less capacity and increased insulation, will be later cooked in wax to remove air bubbles and moisture
14:39 <Kuschelpony> that should run at 1,3kV pp
14:58 <Kuschelpony> then into a two stage cascade for upto 2,5kV DC
15:14 <Kuschelpony> one of my slow moving time wasters, an tiny hv powersupply
15:24 <Kuschelpony> for playing with scope tubes
15:54 <arch> cool
16:48 <arch> but as always, there must be a tradeoff no? you decreased capacitance, but increased the leakage inductance likely
17:01 <Kuschelpony> my longterm plan is to have a pair of them, positive for post deflection acceleration, negative for cathode and focus divider chain
17:27 <Kuschelpony> plus other important stuff, into a very specific power supply unit
19:58 <Kuschelpony> i hope it holds as well as expected how i cut off the top and glued to HV electrode there
31:50 <T3sl4> a few kV isn't such a big deal, it's 10s where you have to do those tricks
32:07 <T3sl4> did you ever see https://www.seventransistorlabs.com/Images/HVPower2.jpg https://www.seventransistorlabs.com/Images/HVPower1.png ?
32:43 <T3sl4> don't have an exact diagram of the transformer but it's pretty plain, actually a lot less leakage than i had wanted, it's more of a transformer than a resonant supply
32:59 <T3sl4> which means the frequency shifts a lot at low voltage / high load, or weirdness like that
33:59 <Kuschelpony> yeah
34:22 <T3sl4> not complaining; more just to say, there's a lot of leeway down here, just insulate it well enough (a few layers of tape basically) and you're good
35:27 <T3sl4> arch: but with higher voltages, you have little choice but to run resonant, and in that case leakage and magnetizing inductance work together, depending on what kind of resonant supply you use
35:27 <Kuschelpony> i have seen windings upto 30kV from early european tube color TV sets, been familiar somewhat with the 18kV Black&White ones, but as my material is not the top quality and my hand winding imperfect, i feel i need more care
36:09 <T3sl4> i think most tube TVs used a pancake winding, with that low capacity fill pattern i forget the name of, and heavily gooped with wax
36:20 <Kuschelpony> have had some early failures of selfwound trnsformers at 2kV where coronadischarges ested away the plastic within minutes
36:28 <Kuschelpony> yep
36:41 <Kuschelpony> but the pancake winding was only for the 30kv ones
36:53 <T3sl4> yeah, it's just enough voltage that tiny air gaps can suffer corona / partial discharge
36:57 <Kuschelpony> the 18kv black and white ones had just cylindrical windings stacked
37:10 <Kuschelpony> i do have a few of them in collection
37:20 <T3sl4> were also some early sets with a mini tesla coil i think, ran separate from horiz sweep
37:20 <Kuschelpony> might digt them out tomorrow for photos
37:29 <T3sl4> the pair got muntzed together later :P
37:37 <Kuschelpony> yeah, like Hawllicraftzers 505

27:13 <Nothing\> heyall
27:35 <Nothing\> lol i just sprayed some CK1 cologne on my boxers cuz it was the only thing i was wearing
27:45 <Nothing\> now my nether regions smell like the 90's
28:09 <Nothing\> i really wish i had a bottle of swiss army too, that was a damn good cologne
28:25 <Nothing\> i used to steal a spray from my friend now and then
29:16 <Nothing\> lol and the spray mechanism on my bottle of CK1 is broken so i just pour it in a derelict battle of rubbing alcohol

34:19 <Nothing\> or maybe i'll try making a program for the altair 8800
34:32 <Nothing\> there's an idea, actually
34:56 <Nothing\> i think il'l do that, even if it just puts a literal in a register, then moves that value into memory

39:43 <Nothing\> heya flyback
39:47 <Nothing\> why wouldn't i be?
39:57 <flyback> was starting to think you od'd
40:00 <Nothing\> also, what's with the running theme of people assuming i'm dead?
40:04 <Nothing\> like, for years
40:13 <Nothing\> flyback, why? i was just in here last night
40:23 <Nothing\> and almost every night for who knows how long
41:37 <Nothing\> but yeah back on my old irc server/channel, if i went quiet for more than a few days everyone would assume i'd died. But I was in much worse shape and actually was at that point

04:03 <Ampera> I love you

04:35 <Ampera> ew gay
04:44 <Nothing\> hey man, do you know anything about basic excell/open office calc usage?
04:45 <Ampera> how are you doing Nothing\
04:49 <Ampera> yes
04:52 <Nothing\> i'm doing pretty good
05:01 <Nothing\> okay lemme ask you this, i've been trying to figure it out
05:05 <Ampera> but I am not at my computer, so this may be a better question for when I am
05:51 <Nothing\> how do you autofill a row or column. Like say I put in 1, 2, 3, 4 and then I want to autofill the next 6 cells with the next numbers, ie 5, 6, 7 etc
06:12 <Ampera> I think you can select them all and drag down
06:19 <Ampera> but I'm not sure
06:36 <Nothing\> i thought you just clicked and held on the first number in the sequence, ie 1, then dragged down to where you want the cells autofilled and press the little square in the bottom right corner of the last highlighted cell
07:00 <Nothing\> but it's just not doing it in mine, so maybe it's something else
07:29 <Ampera> idk
07:29 <Nothing\> -i was arguing with my mom cuz she worked with excel 25-30 years ago so i expect her to still remember
07:41 <Nothing\> yeah i guess i'll have to look it up
07:42 <Ampera> I can tell you when I'm at a computer
07:55 <Nothing\> no worries, i've got google
08:15 <Nothing\> except google's just like "derp here's how to insert the date and time into a cell"
08:34 <Nothing\> when i search "how to autofill cells in excel/calc"
08:42 <Nothing\> excel OR calc
08:51 <Ampera> you might actually have to load a formula for that
09:07 <Nothing\> nah, there's an easy way to do it for simple sequences
09:08 <Ampera> like insert f(x)=x
09:39 <Nothing\> Click and hold the left mouse button, and drag the plus sign over the cells you want to fill.
09:42 * Nothing\ shrugs
09:45 <Nothing\> guess i'll try it
09:55 <rust_collector> EEVBot says something negative
09:56 <EEVBot> rust_collector: nega-tory, ghost rider!
10:12 <Nothing\> okay i was on the right track
10:16 <Nothing\> you click the first number
10:23 <Nothing\> then click the little square and drag it
10:36 <Nothing\> then it autofills the cells you highlight
12:00 <Nothing\> trying to make a spreadsheet to keep track of my memory values via a matrix when programming this altair 8800 emulator
12:16 <Nothing\> i figure it'll be easier if i can see all memory values at a glance
12:57 <Nothing\> it'd be nice if i could find some way to generate a matrix and then autoupdate it as I make changes to the memory values
13:28 <Nothing\> i'd have no clue how to interface a program i make with an existing program like that and take input from it like that
14:29 Quit: Sigyn ([email protected]) Quit: WeeChat 3.0.1
14:34 <Nothing\> unless i use python to generate an AI algorithm that recognizes numbers and updates it based on that so an interface isn't even necessary. But that's way beyond my abilities and probably too much hassle than it's worth
14:55 <Nothing\> seems python or java are the go-to languages for AI these days
16:36 <rust_collector> use rust. it is all fancy and something
18:29 <Nothing\> you mean the game?
18:43 <rust_collector> no
18:50 <Nothing\> I used to know a guy who was crazy about PERL
19:03 <rust_collector> oh, good. I like that guy
19:28 <Nothing\> i tried it, but since it was like 10 years ago and i didn't even know what a scalar was, and that was the first thing it covered. I didn't make it far.
19:42 <Nothing\> i should give it another go
19:50 <Nothing\> i could never get into PYTHON for some reason
19:59 <Nothing\> or RUBY, or TCL
20:07 <rust_collector> what other languages do you know, to some degree?
20:28 <Nothing\> BASIC i got into a bit more as QB64 but since it generates .exes i'm not sure it's a scripted language
20:43 <Nothing\> i dunno if all versions of BASIC are considered scripted or not
21:05 <Nothing\> rust_collector, let's see, well c and c++, or at least i used to
21:32 <rust_collector> sounds good
21:52 <Nothing\> as for assembly, 6502, 8051/52, 8086
22:16 <Nothing\> i mean i can't do anything useful with most of them, but i at least know the basics
22:38 <Nothing\> just sorta trying them out to see which one's right for me
22:54 <rust_collector> mmy brain refuses to learn any kind of programming
22:56 <Nothing\> that and my attention span sucks, obviously lol
23:03 <Nothing\> that's how mine was too
23:31 <Nothing\> that's actually part of why i got into electronics was because I figured i wouldn't have to worry about programming
23:36 <Nothing\> oh boy how wrong i was
24:12 <Nothing\> funny thing is, the other main reason was basically the same reason but with math. I didn't think electronics would require a lot of math knowledge.
24:19 <rust_collector> for some reason, I want to learn awk, or at least a bit of it
24:39 <Nothing\> but It wound up being a happy accident because I found that I absolutely love math when it's applied to real world scenarios
25:06 <Nothing\> and as for programming, embedded systems gave me a whole host of different languages to cut my teeth on
25:18 <Nothing\> i've never heard of awk
26:25 <Nothing\> and honestly, the first time i used a circuit simulator with a an MCU in in it, even though it was a shitty MCU, I was still blown away by how easy it was to use and the flexibility of it
27:03 <Nothing\> it's what inspired me to get an arduino
27:36 <Nothing\> before that i was real bitter about arduinos. I saw them everywhere and in every project and thought they were for loser newbs who didn't care about the purity of the artform.
28:25 <Nothing\> but in reality, the difference between a project that uses an arduino and one that uses actual logic ICs and such is about 30 chips and a shitton more space.
29:55 <Nothing\> one of those popular electronics YouTubers who makes DIY videos made a video where he made the same project with logic chips and then the same project with an arduino and the one with chips wwas so much more bulky and unwieldy
30:58 <Nothing\> and it was basically just a little rail gun type thing where it'd power a series of 3 or so electromagnets to shoot the projectile out
33:34 <rust_collector> I think most people who dislike arduinos, don't have anything (much) against the device, but it is that ide, and the language they use there
35:07 <rust_collector> but, I figured I needed one, because of a famous youtuber... oh well
37:25 <rust_collector> It is not often I use them for anything, but I just think they are neat looking things
37:59 <Nothing\> man rust_collector
38:14 <Nothing\> so i got this "vape pen" for cannibis concentrates the other day
38:21 <Nothing\> it's literally just a battery and nothing else
38:45 <rust_collector> hmmm? how does that work?
38:47 <Nothing\> the concentrates are in these disposable cartridges with the coil and everything built into them
38:52 <rust_collector> oh
39:07 <Nothing\> they're actually pretty nice, they have a ceramic mouthpiece so it doesn't heat up much at all
39:29 <Nothing\> plus the stuff i get is 95% THC lol
39:30 <rust_collector> at least you don\t have to mess with old weird tasting coils
39:36 <Nothing\> so you can't beat that
39:52 <Nothing\> yeah, and you don't have to screw around with pods either, which i've had nothing but problems with
39:58 <Nothing\> plus, it's very clean
40:38 <Nothing\> with other cannabis pens, you get all sorts of resin and tar and oil and gunk that gets all over it and all over the inside parts for the coil and that. It's really messy.
40:44 <Nothing\> but the thing i was thinking
41:11 <Nothing\> is since the so-called "pen" is just a battery that deliners 3.5, 3.7 or 4 volts
41:20 <Ampera> I have limeade
41:32 <Nothing\> i could just as easily solder a wire into each side of the cartridge
41:40 <Nothing\> put a switch in series
41:52 <Nothing\> connect it to my bench poewr supply and use that
41:59 <Ampera> I am in a truck
42:14 <rust_collector> nah, you don't need a switch, just inhale until it is done
42:20 <Nothing\> although i worked out it'd be 10 watts, which for like a 5-7 gram cartridge would probably get really hot really fast
42:26 <Ampera> delicious
42:34 <Nothing\> rust_collector, they got hot fast
42:42 <rust_collector> hey Ampera I was in a truck earlier today, which is yesterday
42:56 <Ampera> cool
43:04 <Ampera> did you have limeade
43:11 <rust_collector> well, I had 2 different ones today
43:22 <rust_collector> no, that is just for special cases
43:26 <Nothing\> Ampera, you should make peach-ade
43:32 <Nothing\> that'd be sooo good
44:05 <Ampera> peach black tea is good
44:23 <Nothing\> that does sound good
44:59 <Ampera> it doesn't sound good
45:06 <Ampera> it really doesn't make any sound
45:12 <Ampera> it tasted good though
45:24 <Nothing\> sure ite does
45:30 <Nothing\> i bet it goes gurgle gurgle
45:37 <Ampera> no
45:49 <Nothing\> like that octopus with brain damage from king of the hill
45:50 <Ampera> why would it do that
45:57 <Nothing\> rip britnanny murhy
46:24 <rust_collector> my peach black tea says WAWAWAWAWAOOOIOIOIOIOIOIOIOIOOOOOOOLALALALALALALALAALALALAAA
46:38 <Ampera> 5G is nice
47:13 <rust_collector> I got the other one, so I am just magnetic
48:47 <DHess_US> In the US, 5G just means that you exhaust your cap in seconds rather than minutes.
49:28 <Ampera> I have no data cap
51:39 * electrohead caps Ampera
52:04 * Ampera unscrews electrohead
54:52 <Ampera> how are you electrohead
55:18 <electrohead> back from the urgent care clinic
55:24 <electrohead> nothing is broke, yay
55:34 <Ampera> nice
55:39 <electrohead> but.. swelled up pretty good, and they noticed fluid build-up
55:45 <Ampera> are you dead yet?
55:50 <electrohead> so, now I get to get in contact with a specialist
56:12 <electrohead> the 800 mg ibuprofen makes me feel partially dead, heh
56:35 <Ampera> can't be worse than being on diphenhydramine for a week
56:40 <Ampera> max bottle dose each day
57:06 <Ampera> and then having a 4-5 day long major headache after that
57:11 <Ampera> I am still dead
58:43 <rust_collector> if 800mg of ibuprofen makes you feel anything at all... you don't take anything very often, do you?
11:25 <DHess_US> I've never heard of ibuprofen having any discernable effect.
14:03 <electrohead> DHess_US: I normally try to stay away from pain pills, it's been many years since I've last taken something for pain
14:08 <electrohead> so, I definitely feel this, heh
14:34 <electrohead> err, that was to both you and rust_collector *
15:02 <DHess_US> ibuprofen isn't a pain pill
15:06 <rust_collector> WOOHOO! mr head noticed I exist!
15:23 <DHess_US> It is a non-steroidal anti-inflammatory
15:51 Join: arch ([email protected]) to #EEVblog
16:01 <rust_collector> but it does help if you have a headache, or something, so I think it is both

30:32 <rust_collector> oh, that is why it is so dark and cold here
30:40 <electrohead> yup lol
34:01 <Nothing\> lol here i am trying to painstakingly make a spreadsheet of a memory dump of this altair emulator
34:22 <Nothing\> when the emulator has an option to dump the core to a plaintext file anyways
35:24 <rust_collector> well, a text file is not a spreadsheet?

35:38 <Nothing\> no, i suppose not
39:08 <electrohead> hey Nothing\
39:11 * electrohead waves and bla bla
41:04 <Nothing\> hey electrohead
41:06 <Nothing\> how's it going?
41:14 <electrohead> eh
41:26 <electrohead> if you read what I said earlier, you'll see my knee is fucked
41:29 <electrohead> lol
42:37 <Nothing\> that's okay, did i tell you my shoulder's fucked?
42:41 <Nothing\> torn rotator cuff
42:57 <Nothing\> it's practically crippled, but at least has like 30% function left in it
43:22 <Nothing\> at least i'm not in constant pain. Just agony whenever i bend it or stretch it wrong.
43:56 <Nothing\> that sucks though electrohead
44:08 <Nothing\> i hope you can get physio for it or whatever you need
44:33 <Nothing\> i got a script for physio and an assessment, plus i'm getting an ultrasound to see if the tear needs surgery to repair it or not
45:04 <electrohead> well nothing is broke, so I'm beyond happy for that
45:12 <Nothing\> since it's been there for at least 3-4 months. It doesn't seem like it's gonna heal any time soon. But tendons are stubborn like that.

54:17 <Nothing\> man, you know what i need
54:24 <rust_collector> yes
54:25 <Nothing\> a good set of graduated cylinders
54:40 <Nothing\> either that or a milligram scale that measures more than friggin 20g
54:40 <rust_collector> no, you need ice cream with peanuts
54:46 <Nothing\> i can't eat peanuts
54:51 <Nothing\> or any nuts
54:55 <Nothing\> not enough teeth
55:05 <Nothing\> i just end up destroying my gums
55:08 <rust_collector> meh.
55:24 <rust_collector> it is what you need. 3d print some tooth

56:11 <Nothing\> which for some reason when i bit something hard with my gums where my teeth used to be, i experience sharp nerve pain. As if I were biting onto it with the roots of my teeth
56:58 <Nothing\> i think my dentist screwed something up cuz i've asked other people who are missing teeth and they said they never experienced that
59:10 <Nothing\> i'm just thinking when it comes time to wear dentures, it might be really painful because of that.

08:43 * Nothing\ gives Ampera a super hug
08:56 <Ampera> how are you doing Nothing\
09:20 <Nothing\> Ampera, find me the instruction in an 8080 to mov a literal value into either memory or a register where it can then be moved to memory
09:33 <Nothing\> i'm doing alright, sleepy, despite my iced cap.
09:43 <Ampera> like the fuck I know what the shit you just said
12:19 <Nothing\> trying to make just some some sort of program for an altair emulator
25:43 <Nothing\> one thing they should done with the altair is had an option where you could have all of the data/address switches reset automatically after each time you either enter data or enter an address to examine
26:31 <Nothing\> when you're entering a program, it's hard to remember to reset all of the switches back to zero before entering the next instruction/operand
26:58 <Nothing\> Ampera, i saw a birthday card at the pharmacy the other day that reminded me of you
27:46 <Nothing\> it was a big bang theory themed one with a picture of seldon that said "don't cry because you're getting older..." then on the inside it says "cry because everybody's stupid and it makes you sad"
28:36 <Nothing\> but i was tihnking that's pretty much how you operate, everyone's stupid and it makes you sad
29:12 <Nothing\> you know what schools need?
29:16 <Nothing\> a research class
31:01 <Nothing\> a class that teaches kids how to do proper research online, how to recognize credible from non-credible resources, to find said credible resources, and it can teach kids to at least partially understand the language used in such papers since it's over the heads of most pre-post-secondary school students
31:58 <Nothing\> at the very least it can make them a bit more comfortable with such language so when it DOES come time to read academic literature they're not scared off by the use of technical language
33:05 <Nothing\> that was my strategy with my daughter and nieces. I'd basically just throw everything at them whether I thought they'd understand it or not because first off, you'd be surprised what a children can understad. And second off, for the reasons i described above.
34:02 <Nothing\> while also stressing the importance of them not worrying about not understanding it so they don't feel dumb for not getting it
40:08 <Ampera> I am disturbed that the big bang theory makes you think of me

49:04 <Halcyon> Morning
50:30 * Ampera hugs Halcyon 
50:33 <Ampera> how are you Halcyon
50:47 <Halcyon> I did a thing
50:52 <Ampera> that sucks
52:31 <Halcyon> https://i.imgur.com/vEMuVdy.jpg
52:43 <Halcyon> I made a 3 cheese and pepperoni pan pizza from scratch. Turned out amazing
53:13 <Ampera> crust is too thick
53:15 <Ampera> beyond that, looks good
53:38 <Halcyon> The base is supposed to be thick, it's a pan pizza
53:47 <Halcyon> It's fluffy but crunchy at the same time
53:49 <Ampera> no, pan pizza is thin
53:57 <Ampera> you've made deep dish
53:59 <Halcyon> Pan can be thick
54:04 <Halcyon> Well yes whatever you want to call it
54:07 <Halcyon> Deep dish then
54:30 <Halcyon> But yes, everything from scratch, the sauce turned out amazing as well. Totally making this again.
54:58 * electrohead pokes Halcyon
55:09 <Ampera> It is an undisputed social crime to make a deep dish pizza in NY
55:25 <Halcyon> There's a lot of things wrong with NY
55:29 <Halcyon> Let's not get started
55:34 <electrohead> lol
55:34 <Halcyon> I refuse to stop making delicious foods
57:46 <Ampera> I didn't say stop
57:48 <Ampera> I just said you are a heathen
58:00 <Halcyon> *shrug*
02:34 <rust_collector> OI! did you make a deep pan pizza?
03:14 <Halcyon> Yessum
03:28 <rust_collector> ok
03:39 <Halcyon> It was yummy
03:42 <Ampera> rust_collector, can you believe this guy?
03:44 <Ampera> I can't
03:46 <Ampera> the audiacity
03:51 <Ampera> the nervosity
03:58 <Ampera> the brazenacity
04:02 <rust_collector> well, I am not sure, but I think he might be able to make a pizza
04:12 <Ampera> baldercrap
04:23 <Ampera> pizza is illegal outside of NY
04:35 <Ampera> we invented it, it's cultural appropriation
05:08 <Halcyon> I thought pizza was created in Naples?

06:00 <EEVBot> [Title] - Rome, New York - Wikipedia
06:00 <Halcyon> When people think of "pizza" they don't think "American"
06:07 <Ampera> No, they think NY
06:11 <Ampera> or if you're inbred, they think Chicago
06:17 <Halcyon> No, they think Italian
06:23 <Ampera> yes, Italy NY
06:29 <rust_collector> up here, we have american pizza, and italian pizza. they have their own pages in the menu
06:31 <electrohead> When I think of pizza, I think "food"
06:39 <electrohead> Plain and simple.
06:41 <Halcyon> I do however like New York style pizza
06:48 <Halcyon> All pizza is good actually
06:51 <Ampera> the only other valid type of pizza is greek pizza
06:52 <Halcyon> I've never had a bad one
06:54 <electrohead> It's food, it taste good, and that's it. No arguing
07:01 <Ampera> but that is also a thoughtcrime punishable by forced reeducation here
07:04 <Ampera> it's not that bad though
07:07 <Ampera> they just make you eat NY style for a month
07:18 <Ampera> but I like to argue

07:52 <rust_collector> the best pizza is rectangular, then you roll it up, and slice it, add cheese and stuff on the new top, and...do pizza things with it
08:00 <Halcyon> If you're going to argue Ampera, at least try to be right :P
08:12 <Ampera> I think you'll find I'm as right as they get.
08:17 <Ampera> Hitler would shit his pants
08:20 <Halcyon> Oh yes, we know that
08:33 <Ampera> I'm so right I flipped the chart and am actually a fierce stalinist
08:45 <rust_collector> well, that is not fair, most people of that age do
10:08 <Ampera> if I ever buy a 7 string guitar I'm tuning it in CABBAGE
10:13 <rust_collector> my phone is updating. it says it has 437 apps. I wonder what they do

11:20 <steve30> I hadn't actually looked at the site yet, I was more interested in seeing their acting performances
14:06 <jaymax> The performances reminded me of a culture jam skit when prostitutes responded to a modeling spot "for" and in front of American Apparel a decade+ ago, but the Barclays trial was much more refined.

42:11 <electrohead> it definitely helped a bit, but wearing off slightly
42:59 <Halcyon> Have a beer
44:21 <electrohead> Fuck no
47:49 <Halcyon> Hehehe that doesn't sound like you
49:08 <electrohead> Why would I drink with pills?
50:01 <Halcyon> It's only Ibuprofen
50:41 <Halcyon> There are no contraindications for taking both, you just might feel more sleepy than usual
54:06 <electrohead> I'm good
54:28 <Halcyon> Cranky pants
