STM32G431 Analogue TV Transmitter

Monday February 16 2026, 2402 words — Broadcasting TV with almost no parts

If you follow me on mastodon you might know that I have a bit of an obsession with vintage analogue video cameras. They’re great. I love them. I can’t stop being weird about them. So a few weeks ago I felt like it was finally time to take the next step and get myself one of those “televisions” I had heard so much about. Stop feeding those pristine analogue signals into a digital capture card and instead enjoy them fully analogue, end to end, crt to crt.

Raspberry Pi Media Player

A pretty common task for exhibitions I support is to have some kind of tiny unobtrusive media player box that can play a bunch of video or audio files on loop for anything from a small listening station with some headphones to a 4k projector showing a feature video.

Since this has come up again and again for me and I’ve had multiple different versions of a setup like this for which I’ve somehow managed to loose all the source files I’ve decided to write this blog post in the hopes that when I have to do this again I’ll actually remember how I did it this time.

I’m not gonna go into every detail here, like how to set up systemd services, but if you want to take a closer look all the scripts and files are available for download at the end of the article.
