I decided to upgrade the sucky blue laser in my laser projector, and now it can be used as a "burning printer" of sorts.

The old laser was 405nm (almost ultraviolet), 100mW. The new laser is 445nm (bright blue) with a G-2 lens and a maximum output power of 2000mW, but I'm not able to run it at full power yet due to cooling issues. So instead of using 5 volts at 1.5 amps, I'm currently using 3.5 volts (due to my own laziness) at 1.1 amps. Any higher and the driver board's heat sink gets much too hot to touch (the heat sink is only rated for 0.5 amps, anyway).

I hand-traced this graphic as part of a laser show which I made (http://www.youtube.com/watch?v=yFOJoblrFqI) for an event on the 11th of October called "WOTA London" (episode 12)
