DIY Laser Projector using Mirrors and Motors!

Couple years back I made a laser project with mirrors and motors (you can see my laser projector here) but here’s another great DIY laser projector using motors and mirrors, much more advanced.

The main hardware setup consists of a Laser and two motors. A mirror is attached to each motor in a way that the mirror is slightly tilted to the axis of the motor. when the motor rotates the mirror the plane of the mirror is not flat and projects the laser in the form of circles. each motor creates a circle from the light falling on it. this combines to create circles within circles thus creating the effect. to add to the effect the laser light is pulsed using PWM which breaks the circle into lines further enhancing it.
