My Sony TV also faced some issues in the past, which at least let me start some investigation. Unfortunately it confirmed my assumptions that the hardware is very limited and already runs on full load most of the time. Still thinking about putting some more effort into this, but killing the device was also one of my concerns.

A really fun project was extendending the abilities of my reMarkable Pro. I missed a decent Manga Reader on the device, so I created a native one which makes use of my custom server.
