mitxela has built an #LED matrix earring from 52 0201(!) LEDs (i.e. 0.65 × 0.35 mm footprint) on a 9 mm diameter circular PCB. Or rather, two PCBs soldered back-to-back because this density of components basically requires a four-layer PCB with blind and/or buried vias, which would've been very expensive. The video also features a "very cheap" (3600 USD) pick & place machine. I expect these to show up in makerspaces soon.

@xerz oh shit that's potentially really useful in legalities where you can't waive copyright
@hellomiakoda EPG is a newer system that encodes the program data in a computer-readable fashion.
Teletext just encodes text and very blocky images on a limited number of pages. Stations are free to use that however they like, though usually there's program info, news and weather. For subtitles they just showed the Teletext page number and you had to navigate to it
ARD still maintain theirs, you can use it online to read German news or on a TV that supports HbbTv

@eldang that's even weirder
if I ever buy a laser printer I'm putting a power monitoring plug on it, that's for sure
@hellomiakoda (we never had close captioning signals, tv subtitles in Germany were Teletext)
@hellomiakoda DVD video is MPEG2, the subtitles are four-color bitmaps or added as metadata, encoded by the DVD player's TV analog tv generator
@hellomiakoda the extra info is written in lines that don't show up on the screen (because the cathode ray is switched off then) so they don't get preserved in the conversion
@eldang that sounds like a bug or a high-availability setting, it really doesn't take long to heat up the drum when it needs to print (and it can be done while the print is transferring) so it can totally let it go cold
@monorail I wanted to try some over the winter holiday but uhhh the basement flooded
@monorail yeah they have been for a while now
@laravortex@mastodon.social hey @1337core tag deinen ai-slop doch wenigstens
@ralesk MSKLC is not an option as I am on a "secure" work machine
https://github.com/yt-dlp/yt-dlp is always free. I don't know why this is a reply to the previous tweet I'm trying to fix it
Nimona is free to watch on Netflix's YouTube channel until the 26th https://www.youtube.com/watch?v=i4CFWTYFRlw
