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). Many parts were salvaged, for instance, from a DVD burner, a printer, and a “disco ball.”
