I finished the next version with galvos and now it's close to perfect.
I quickly designed and 3d printed a frame for all parts and was able to fit everything into a surprisingly small enclosure.
Controlling the diode with PWM I set the brightness to a level where it doesnt disturb sleep at all and it still saturates the GITD material quickly (a few sec to draw the time).
Also when drawing slowly with the galvos they make absolutely no sound at all.
Heres some photos of the messy prototype and gif of my bedroom ceiling in a very dark room.
