Remember Carl that made the Spinning RGB LED Ball Display? He has also built a wicked RGV Laser System! I can just imagine using this at the center of a big party. You would have to pass out eye protection though. 🙂
"Three laser beams in primary red, green and violet are combined with the optics harvested from an HD-DVD drive to make white. The total output is 350-400mW, and wavelengths are 660, 532 and 405nm. The homemade TTL constant current driver modulates the lasers to simulate over 16 million colours from an ordinary RGB LED-circuit with PWM, amplified by transistors."

Oops, I got that link wrong. Thanks for the catch.

With the appropriate shutter and scanner you’d have the world’s biggest color projection display in no time.

Is there any chance for some diagrams or build information. It would be really helpful 🙂
