Default Open Source CRT Monitor

This guy (Thomas Daede) has spent two years designing new, modern, open source hardware to drive old CRT tubes. This is his working prototype:
https://vimeo.com/591387422

His aim is to be able to bypass all the old circuitary in any failing/failed monitor or TV, eliminating the time needed to figure out what's wrong. His new system gives error codes so if it does fail, it can be troubleshot much more easily.

There's interviews on YouTube with him where he explains it all in greater detail:

Perhaps I'm missing something, but I can't quite see where the EHT comes from other than the old monitor. As this is potentially the most unreliable part of a monitor redesigning this would be important I would have thought.

There's an output to feed the EHT transformer, or so it seems.

Yes, I saw that, but of course that pre-supposes the LOPT is good. However, I imagine as long as it provides EHT it's not such an issue.
Interesting, but not quite sure of its practical value.

Seems to be geared towards retro computer and video game enthusiasts whom often favour CRT TVs/ video monitors as their display of choice ..to the point of obsession!

In the interview (more recent than the prototype video) he says at 39:35 he's using a newly manufactured flyback.

Elsewhere he's stated all you'll ultimately need is the tube and the yoke, everything else is replaced with readily available modern parts.

On his github page: https://github.com/tdaede/td-crt

I managed to view the kicad_sch files (schematics) by downloading them and uploading to https://www.altium.com/viewer/.

The PCB designs are also there. Bear in mind it's still a work in progress.
