An electronics student Poland is well on his way to a lucrative career if he keeps coming up with great projects like this RGB laser projector made from scratch. All the components are mounted inside an aluminum briefcase with a hole in the side for the projector.
This laser projector features lasers of varying colors which (using mirrors) can be merged to create graphics on command. A fair number of the parts were scavenged from items such as a printer, a disco ball, and a DVD burner. All this (and more) was mounted onto an aluminium plate and mounted into the briefcase. Check out the project build info including additional pictures and how-to’s.
