ok, well it's good I got 2 of them. By the way, does anyone know what brand the module is?
I'm also going to use a capacitor, a switch, and camera flash circuit board to keep from having the laser on for very long (I don't know if that helps with the laser's life while on, but I do know it does when you factor in off time). But the problem is I don't know how to calculate the time the laser module will be on with that kind of setup when the capacitor is full and switched on. Also only thing I know for certain about getting the right capacitor is it has to be 3 volts.
