Gemini Laser Launcher

Classic laser effect that has been copied by many. Manufactured by Gemini (whose lighting division later became LyteQuest), features a 4.95 mW red laser diode that shoots on to a sound active spinning rod that has 8 small mirrors on it. The mirrors are a bit off center from each other so it will not hit more that one mirror at a time.  The microphone has a sensitivity adjustment knob where the power goes into the unit. The output is laser beams that shoot out 1 at a time and scan a high rate of speed.  Very cool unit!
