Carl has built some lasers that have been featured here in the past. Well he has sent in his latest creation. It is a small metal box filled with a microcontroller driven array of lasers! Thanks Carl. “My latest work using three lasers (red, green, blu-ray) combined with optics from a HD DVD drive mounted in something called an white fusion kit. I designed a driver circuit to control the lasers with PWM from a PIC to make millions of colours and it has lot of built-in effects.“

This is a pretty amazing hack.

You see him lighting a match with the laser.. And then he is filming straight into the beam.
It’s a nice toy, but how dangerous are the rays?
March 4th, 2010
awesome but i hoe you are wearing safety glasses.

An RGB laser is definately on my post-lottery-winning to-buy/build list.

Pretty freaking unsafe, unless the guy’s wearing a blindfold or welding helmet. As I understand it, laser safety glasses generally are designed to block a narrow frequency of light, which means that you’d need to wear three pairs (one for each color) to look at this one safely.
Still cool though.

No, I didn’t use laser safety glasses for reasons posted above… But I used the next best thing: my camera. The beam is very hazardous, about 450mW.

Thats fantastic. Some big rays there tho. 450mW is high frequency eh. Good work!

[...] How much current does this put out you ask, a whopping 8 plus amps! Yes, this is the same Carl who normally works with lasers, seems like he is branching off into LEDs [...]
