I appreciate the response, let me Elaborate.
Lasers used in this system use a 780NM IR laser operating on 4, 14, 24, MS wavelengths.
They work off a 3V power source.
I would like to have something small enough to fit down a muzzle of an airsoft gun and to possibly fire off of vibration from the gun itself. Hard-wiring the trigger to use as a device is also possible.
My goal is to have a laser system made by me to operate on this system with minimum cost.
Does this clear it up?
