Homemade Full Color DVD Laser Projector
I love video projectors, and have used one instead of a traditional TV for almost 6 years now. The only serious drawback, in my experience, is the expense of the bulbs, and I expect that it will not be very long before full-color laser diode projector technology overcomes it. Red, green, and blue laser diodes are already accessible; the trick seems to be in scanning the beams in an economical and reliable way.
