The build is complete.

The system runs stable, all components are in place, and the device behaves as intended.

There are still ideas for future extensions.

Different CRT color profiles.
Streaming audio via SSH.
External modules, possibly even a Geiger counter.

All of that is possible.
None of it is necessary.

For now, the device does exactly what it was built.

Thats enough.

Thanks to my family ❤️ who gave up many hours while I was down in the basement working on this. 

Thanks to AkselK. for printing the custom power supply enclosure.

Thanks to RF-Elektronik in Augsburg for supplying all the small parts — one of the few remaining local electronics shops where you can still buy solderable USB connectors, waterproof switches, and countless other essentials at fair prices.

Thanks to Enzo for lending me the multitool. It didn’t survive — but don’t worry, what you get back is brand new.

Thanks to the developers of cool-retro-term — a great window into another time.

Thanks to ChatGPT — without it, I wouldn’t have been able to write a single script.

And thanks to all friends who patiently listened to my long explanations about this project. ;-)
