I have a laser diode module that normally operates from two AAA batteries that produce a measured 1.27 mA at 3 V and I want to run it off of a 7-cell NiMH battery pack that produces a measured 5.3 mA at 9.56 V at full charge. (It's for an integral aiming device for an airsoft gun, in case you're wondering.) Given that I = V/R then 7k ohms of resistance should give me the proper amperage, but how do I reduce the voltage to the necessary level?
