02:31:09 <arch> me waiting for the snow to accumulate so i can put my snowblower to use: https://imgflip.com/s/meme/Sad-Pablo-Escobar.jpg
02:31:21 <arch> only currently up to about 1"
02:35:10 * arch pelts Ampera with suspiciously yellow snowballs

02:38:27 * flyback rubs nothing/ on outside
02:44:32 * arch rubs snow on flyback's nipples
02:50:24 <Kuschelpony> have you estimates where the practical limit of a voltage multiplier is, for example if it works well enough to use maybe 12 stages to reach 10KV with commonly available 1KV capacitors and UF4007 for rectification
02:52:52 Quit: Kuschelpony ([email protected]) Connection closed
02:59:48 <arch> i would have to guess where corona discharge makes the stage lossy enough that caps dont maintain charge. could be wrong tho

03:19:24 <Kuschelpony> arch, do you also have something without videos?
03:19:50 <arch> if it is privacy you are worried about, you can use yt-dlp to download youtube videos locally before watching them
03:20:13 <arch> it is impossible these days to completely avoid youtube or internet videos
03:20:28 <rust_collector> he seems to manage
03:20:34 <Kuschelpony> its because of the format of forced to watch moving images and speech by someone else, versus text to read
03:21:01 <Kuschelpony> i just cant follow videos or audio podcast
03:21:52 <Kuschelpony> btw: if someone asks about current, less than 100µA
03:22:47 <arch> luckily for you, AI these days transcodes videos
03:22:51 <arch> to text

03:51:56 <arch> Ampera, are you ok? are you ok Ampera? or have you been hit by, you've been struck by a snow plow?
03:52:20 <Ampera> I'd rather be a smooth criminal
03:52:31 <Ampera> snow just started getting started here
03:52:38 <Ampera> not too much on the ground yet
03:52:44 <arch> ahh, it's been snowing here since like 7
03:55:06 <rust_collector> psnow
03:56:17 <Ampera> rust_collector, we are getting just a light dusting between 45 and 60cm
03:57:16 <rust_collector> we will see about that. weather is... like weather. But that sounds nice, and should cover up any evidence outside
04:01:23 <rust_collector> time to go drifting in an old school bus. that seems nice and american

04:18:34 <arch> rust_collector, don't forget to blast eurobeat tracks
04:19:33 <rust_collector> eurobeat uhm. sorry, I am not american, or from continental europe. dunno
04:24:42 * steve30 plans a snowball fight with Ampera
04:24:56 * Ampera pets steve30 gently instead
04:31:24 <arch> neither are the japanese, but they seem to like both drifting and eurobeat. if Initial D is anything to go by...
04:31:46 <arch> GAS GAS GAS! I'M GONNA STEP ON THE GAS!

12:07:26 <arch> T3sl4, have you messed with piezoceramic transformers for any of your gadgets yet? https://ceramics.org/ceramic-tech-today/sick-of-the-brick-piezoelectric-transformers-poised-to-shrink-power-converters/
12:07:27 <EEVBot> [url] Sick of the brick? Piezoelectric transformers poised to shrink power converters - The American Ceramic Society | ceramics.org
12:07:42 <T3sl4> nah
12:07:53 <arch> is it a bunch of marketing gimmick right now?
12:08:14 <T3sl4> don't know what they're good for
12:08:20 <arch> oh
12:26:00 <arch> T3sl4, on this appnote, page 16, figure 22, will this work for any non-synch buck reg? what are the limitations? it seems like the downsides are requiring a matched pair double pnp, and lot more board space: https://www.analog.com/media/en/technical-documentation/application-notes/an30fa.pdf
12:26:58 <arch> and if the switching frequency is high enough, is there a risk of shoot through, is what the 3rd downside might be
12:27:14 <T3sl4> ew yuck
12:27:16 <arch> depending on max duty cycle
12:27:48 <arch> why is it bad?
12:30:18 <T3sl4> voltage mode
12:31:13 <arch> oh
12:31:28 <arch> so this same setup wouldn't work for current mode convs?
12:31:54 <T3sl4> look at 1072 block diagram
12:32:08 <arch> looking...
12:32:34 <T3sl4> these values are preposterous, 100uH and 1000uF for 5V 5A
12:32:41 <T3sl4> but it does say 1989 publication
12:33:32 <arch> "The LT1072 is a current mode switcher" is what it says in there
12:33:36 <T3sl4> or the -5.2V reg, no one uses ECL anymore, PECL sometimes
12:33:43 <T3sl4> block diagram *taps on glass*
12:34:33 <arch> T3sl4, https://static.wikia.nocookie.net/memepediadankmemes/images/5/5b/That_Sign_Can%27t_Stop_Me_Because_I_Can%27t_Read.jpg
12:34:46 <arch> ok, let me look again
12:34:59 <T3sl4> https://i.imgur.com/06Rwwij.png
12:35:24 <arch> lol
12:36:47 <arch> ok so i think where you're getting at. the output's emitter is tied to ground, so all it can do is pulldowns
12:37:19 <arch> so for example the TL494 in buck config, should be able to use the same config?
12:38:06 <arch> but modern buck regs which are push pull, are not able to. am i on the right track?
12:38:41 <arch> derp, the word i was looking for is open collector output
12:38:55 <T3sl4> just one more thing
12:38:58 <T3sl4> that current
12:39:01 <T3sl4> what current is it drawing
12:39:54 <T3sl4> in the Fig22
12:41:06 <arch> it's not able to directly sense the output current sourced/sinked by Q1 and Q2
12:41:53 <arch> whatever current limit is only applicable to Q3, 4, 5's gates?
12:44:22 * T3sl4 rings bell
13:16:50 <arch> recommend you grab a used snowblower off auction for like $25 like i did. literally all i had to change was the sparkplug and carburetor ($12 in total)
13:57:38 <arch> T3sl4, you might like this one: https://www.reddit.com/r/interesting/comments/1qkkty1/tesla_bug_control/

14:10:50 <MrMobodies> it's for the TV screen for my disco's where I'd have the song request list on the left.
14:17:30 <Halcyon> Kind of want pancakes now

16:32:32 <steve30000> o/
16:42:45 <MrMobodies> What do you think of this weather forecast design?
16:42:46 <MrMobodies> https://www.meteoblue.com/en/weather/week/peterborough_united-kingdom_2640354
16:42:47 <EEVBot> [url] Weather Peterborough - meteoblue | www.meteoblue.com
16:44:33 <MrMobodies> Without any changes like implementing the table from the previous design exactly the way it is on the METOFFICE and when they get rid of switching to that previous design, I was thinking this might be a better alternative
16:45:19 <MrMobodies> it's not in the way I like but it does have a table where I can see the information easily and easy to read in compact form
16:45:27 <MrMobodies> instead of it being bloated
16:45:53 <MrMobodies> the table below is the one I like
16:46:25 <MrMobodies> a bit overdecorative though
17:06:16 <steve30000> looks quite good actually
17:21:45 <MrMobodies> looks at the MetOffice Tristpilot

17:22:28 <MrMobodies> I found 6 days ago they changed their "app" and complaints there too
17:22:41 <MrMobodies> I don't use the "APP" myself for something so simple
17:23:17 <MrMobodies> Last few 5 star reviews Jun 22 2025, and December 25 2025
17:24:05 <MrMobodies> 4 days ago "new app its soooo dark and hard to use...."
17:24:51 <MrMobodies> "Yes the new one is prettier but the UI is horrible: it's no longer a functional weather app. Uninstall it"... Form over function is all they seem to care about.
17:25:17 <MrMobodies> Pretty, modern, newer, trendy = good = better, despite the backlash.
17:25:54 <MrMobodies> "The new widgets no longer fits on my home screen."... Bloated is what I think they mean.
17:26:37 <MrMobodies> "Terrible! Changes to the app make it difficult to read on a phone. Always used in preference to the BBC Weather app but now met Office is worse than the BBC. Please change it." Exactly.
17:27:10 <MrMobodies> 580 reviews 93% 1 star and 4% 2 star.
17:30:15 <MrMobodies> 8 pages of 1 star reviews since that new design went up so that 8*21=168, the rest before that seems to be about accuracy.
17:34:44 <MrMobodies> Looks like this might have had something to do with their new design

" specialist for the website CMS."... "...User Experience Manager gaining insights from our users to feed development"
17:37:48 <MrMobodies> They receieve negative feedback (reading from the likes of Reddit) and they seem to make it worse." Well done MetOffice employ someone to do that.
17:39:05 <MrMobodies> Oh "an opportunity to join Graduate Development Scheme once you have compete yor University studies"
17:41:04 <MrMobodies> Degree on marketting... how can we make users see our forecast better, zoom in on it and make everything bigger. I think I get the picture now.
