I found the CRT TV my parents used to have when I was a little kid. And I could even buy it right now for 25$ I think it looks cool and kinda want to But I'm not into CRTs, and I really don't have space for it. Also it weighs just as much as I do XD

CW: Some loud noises Fun little project I've been working on - storing digital data on VHS. It now actually works, I'm able to encode, write, read back and decode the data without errors at ~110kB/s. But in this video I decided to play a FLAC file while it […] [Original post on social.mango.vg]

Now that I can both encode and decode B/W PAL signal in software, here is some "A kockásfülű nyúl" that was encoded, played back by a DAC (osmo-fl2k), recorded on VHS, played back from VHS, recorded with an ADC (cxadc) and decoded. Not perfect, but […] [Original post on social.mango.vg]

Using Conexant CX2388x as ADC with github.com/happycube/cxadc-linux3 It works quite ok as an oscilloscope, though it's obviously not good for measurements, just for looking at the signal. And it has no bandwidth limiter, so aliasing is possible.

After reassembling this thing way too many times, it's finally done (including all the software to run it). I've added some sound deadening to make it quieter. So far it runs well and consumes little power (<600W), but time will tell when summer comes.

What some people really want is a “this game was made by people who share my political opinions” checkmark, but that would be too on-the-nose so they campaign for proxies like AI disclosure instead.

Quoting Tim Sweeney's:
Agreed. The AI tag is relevant to art exhibits for authorship disclosure, and to digital content licensing marketplaces where buyers need to understand the rights situation. It makes no sense for game stores, where AI will be involved in nearly all future production.
