This is pretty cool. Has anyone ever seen a diy star projector for the home? Most of these toy star projectors like the Sega Homestar require placing the projector at the center of the room to point up. At the same time most of the small active projectors (like for movies) require a screen for the image to be better seen (they aren’t very bright). Ideally I would like something that could autocorrect the dimensions of things on the surface, so it would project distorted in a way that it would visually look non-distorted and also I would be looking for the cheapest projector that still manage a good bright for stars during the night, without requiring to put a screen on the home ceiling.

I’ve seen proper star projectors from Zeiss but my ceiling is not a dome - plus expensive and requires infinite amounts of power..
