TinyProjector: Mini POV laser projector


I found [Stefan]‘s work through his older, but interesting TinyProjector project. He opted to use multiple diodes in various configurations with rotating mirrors to create images. He’s built quite a few interesting projects over the years. The WeatherTank is pretty sweet.

AVR Laser Projector


I’ve seen a few simple DIY laser projectors that just oscillate the beam. This one (scroll past the pong game) has 16 lines of resolution. Sixteen mirrors are rotated by a motor, and an AVR controller pulses the laser to draw the image.
