What's the recommended method of adjusting the power on the typical 3v laser modules (12x30 or 6x10).
I want to set it up so that I have full power or 1/2 power controlled by a switch.
Is it easy to hack the modules? Is it as simple as a resistor change?
I don't think it's quite as easy as lowering the voltage (by sticking a resistor in series, is it?
It's the current that needs to be varied to dim an LED, or am I incorrect?
