Scratch Built RGB Laser Projector

Scratch Built RGB Laser Projector

Karol Łuszcz is studying electronics at Poland’s Gdańsk University of Technology. I’d say he’s on-track for an impressive career. This vector-graphics laser projector, his third prototype, includes three laser modules at 650, 532, and 405 nm wavelengths (making it more of an RGV projector, really).
