Transcript of Laser Spirograph

How does it work?
A laser beam is reflected off two mirrors to a wall. As this is happening, both mirrors are spinning at high speed, by the usage of motors
How its made
Schematic
How its made
Solder wires on both of the motors and connecting them to the batteries. You will want to attach your mirrors very early in the building process. There is no specific way to do this. Gluing the mirrors to cardboard works.
Potentiometers are important for the Spirograph, as you need a way to control the speed easily. So use a breadboard(circuit board) to connect the motors and potentiometers
Remember to connect the switch to the laser pen for easy access to turn it on

What is it?
A Laser Spirograph is a circuit projecting laser images on a surface

This eye-capturing device uses the speed of turning motors to create patterns or designs

Laser Spirograph
Materials:
-laser pen
-2 mirrors or more
-AA batteries
-plenty of small wire
