Laser ohm resistor project question Answered
So I am doing a big modifiction of Kipkay's burning laser project. I am making it into a gun, and the only resistor I can find is a 4.7. Will that do? I have a 5mw module like his, and a 250mw 650nm laser diode. Also I am going to use two C-batteries, so its 12volts total.
