DIY Laser Image Projector (100ft+ Range!)
I created this unique laser device which can project raster images, like Gifs, over long distances. It uses a combination of a high speed rotating mirror and a galvo to draw each frame. With a resolution of up to 320x120, it's not exactly HD, but the aesthetics are incredible!
