[Cyborg] 200 laser diodes

Indeed!  My plan is to basically hack a North Paw board into doing the 
work, but according to my calculations you should just be able to use an 
Arduino.  50mW laser diodes.  If we assume they have a 3V drop (the page 
says "battery: 3-5V"), that means 16.7mA each, which you can drive with 
an arduino pin.  Anyone know the total power an Arduino can drive/sink? 
  I'm just wondering how many of the pins you could have going at once...
