[PuffMag1cDrag0n] shows us how to make a fairly easy projected LED display. The projector is made from a 13×7 LED matrix and a couple fresnel lenses. The layout and construction is similar to the Lumenlab projector setup, only replacing all the lighting and LCD with an LED array. It communicates through serial port and is powered by a picture micro 16f648. We would love to see an RGB version of this. The directions are a bit rushed, but you ought to be able to get the gist. just remember that you need some pretty powerful LEDs to throw a big image.
