Cut a small round piece about the diameter of your batteries. The copper on one side is isolated from the other side by the board material between them. Solder a low value pot to two wires, then solder one wire to each side of the board. Put the board between two batteries in series or between a battery and a battery terminal in the laser. Adjust the resistance with the pot to control the brightness. Joe Larkin __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
