Last month we had the pleasure of bringing you [FireMyLaser’s] green laser spirograph. Just green is great for a while, but why not add red and blue for a full spectrum of color! [c4r0] steps in at this point to bring us his red green blue laser. He dug around inside Blu-ray players and DVD drives until he had a collection of lasers, refractors, and other filters that fit his needs. With some careful toothpick alignment and glue, his setup was complete.
But then he went further by modified his galvo scanner to accept the RGB laser; requiring a custom circuit board and new software, both available on his site. The original is in Polish, but Google does a decent translation. Check after the jump for a video.
