Hand Held Video Projector
This just so cool. Its not on the market yet, but its a pocket sized full color video projector (the model pictured is monochrome). Uses laser diodes (one of each red, green and blue) to draw the image. They don’t explain the details, but I bet it uses a DLP or equivalent. Lite Blue Optics (the creator) claims only 1.5 Watts at max power. That means it could be powered by the battery in your PDA or cellphone. My one concern, its so small that tension on the cables that connect it to the PDA/cellphone/computer could cause the projector to refuse to stay level.
