@concretedog@mastodon.social ohh, and of course you need to make an issue on github to opt out. so people who deleted their accounts there are just fucked I guess

aaaand here we go, composite video and line level audio output on the TVTHING with the latest version of tinyvision. for all the ones who want to keep the airwaves clean.

@karotte you know somebody somebody implemented a driver for this by transcribing that table into a header file…
cursing the person who made it impossible to get a cheap camera in europe that can record for more than 29 minutes and 59 seconds as I try to record a video of me playing back a 30 minute record
why am I considering buying an old PDA off of ebay?!

ok, the masses have spoken, PCBA data for JLC is now available for download on the refs tab on sourcehut and included in the sources

@kirakira she was the first piece of furry art I've ever seen after I clicked on "random article" on Wikipedia in 2008 and laded on the page for furry fandom! Things would never be the same after…
Ran a bit of a long term test with my VTR to see if it's stable and I was able to record around 17 minutes before it started losing sync again. Ugh…
So either the drum speed is slowly drifting as it warms up, or the camera frame rate is slowly drifting, or the load on the motor increases as we get towards the end of the tape, or it's something completely different…
I should probably repeat that test with a quartz locked camera to at least mostly rule that out as the source of the problem.

ok, so, here's a question about PCB releases: I get my PCBs from JLC and do all the part assignments for PCBA inside KiCAD using the JLCPCB plugin, which means all the production data for getting your own boards made it right there, but I don't usually include it in my releases because I feel kinda… icky about including files for a specific board house?
Like, they're not paying me anything and I don't really want to favor one company over another, but I do realize that it would be handy for people to just have a file they can upload somewhere and get boards in the mail a few days later. How do you feel about including production files for specific manufacturers in open source releases?

@penguin42 I totally didn't steal that idea for the pads from @ArchiteuthisFlux
Teletext should be possible and would be a super cool addition! I don't have a TV that can understand teletext though…
Ohh god, I'm gonna have to get a TV with teletext now and display my fursona on teletext, do I?

@MLE_online well, you just made me go measure mine, and it has an internal diameter of 42mm

@dtl I don't think so. It does get pretty bright, but turning up the brightness just washes out the image. I might do some basic reverse engineering to see if I can just drive the control grid a little harder maybe to push it deeper into cutoff for the black parts of the image

@kkarhan I've thought about some kinda cyberdeck thing but I really don't need another general purpose computer in my life. A calculator feels like something I'd actually use on a day to day basis
anyone here has any experience doing remote debugging on ARM devices using Gram/Zed?
I've been using cortex-debug in VSCode before but there is no such thing for Gram yet. I tried setting things up manually but had no real success. I can get GDB to connect to OpenOCD but I can't get it to automatically reset the device and upload the new binary. Giving GDB a file with startup commands just makes Gram lock up when starting the debug session.

@f4grx the plugin isn't made by JLC, it's all volunteer work. And you can't get around *some* level of non-standardness when assigning part numbers from a catalogue cause every manufacturer is gonna have a different inventory system for the parts they offer.

@doragasu mine draws around 380mA, so actually more like 4.5W. Definitely needs a chonky battery.

@kkarhan I really don't need a fourth oscilloscope! I could use it as test monitor for my way too many old TV cameras, but the image quality really isn't good enough for that.
I am planning to implement GUD into my tinyvision library to enable using it (or any other old TV) as USB monitor though.
Replying to
@doragasu do you assign the LCSC part numbers inside kicad? Or do you leave that up to whoever orders it?
Replying to
@gsuberland Well, I just need to drag and drop some zip files onto the source hut release page…
Replying to
@amy well, just up until now I thought the plugin keeps the LCSC mapping in it's own database but apparently that's not always the case, because some parts have an LCSC field while others don't, even though they all have part numbers assigned in the plugin. Not sure what's going on there, tbh…
Replying to
@Laberpferd Just one chip, actually. An LA7806 sync separator/deflection oscillator. Well, and a 7810, if you want to count that as "chip".
Replying to
@f4grx the plugin adds an additional field with the LCSC part number to the footprint. Everything else comes from the schematic.

oh no… just found somebody selling a huge pile of old east german and soviet test equipment, radios, TVs, video cameras and similar stuff locally on kleinanzeigen D:

@vicash the fabrication data for getting them made at JLC is on sourcehut. Depending on where you are in the world I could also maybe post you one?
Replying to
@mossmann Ohh, that's good to know! Though tend to stick to the default ones, the more basic the better.
Replying to
@doragasu how does it handle part assignments for PCB assembly? I've only ever used JLC, so I'm not exactly sure how other manufacturers do it
Replying to
@f4grx actually, it seems to write the part numbers to the footprint metadata? at least, like… on some footprints? I'm honestly not quite sure what's going on…
Replying to
@Laberpferd I think they modulate the horizontal deflection voltage, or at least that's part of it. There is a potentiometer to adjust the keystone distortion but I'm not quite sure what exactly is going on.
Replying to
@doragasu yikes…
how the hell would that even happen, that inductor isn't even exposed in a spot where it could rip off…
