Simple Laser Show These type of laser shows are so cheap now, it is not really worth building it yourself, but I tackled this project when they were still around $80. You can find commercial systems on sale for around $30 at local music/guitar shops.

Long Time exposure showing you a longer trace

Simple spiral type laser pattern is created by 2 spinning tilted mirrors and a laser pointer. The speed of the 1.5V Radioshack motors is controlled by a 5V power transformer and a 25Ohm trim pot (variable resistor). I had each motor on a separate trim pot using the same power supply.

Please use safety in mind when displaying your laser show.
