Laser firing sound?
I need a simple cheap way to make a laser during sound fir a project. I don't want something complex like the stormtrooper blaster, but a simmilar sound would be neat. I can fit 3 9v batteries into the case. Also note I will be using a momentary switch to power LEDs fir a flash effect, and I don't want to gave to turn it down. Simple and small is what I need. Whatever works gets best answer and credit in my instructable.
