Since 1857, when the scientist Jules Antoine Lissajous studied these kind of figures, they have been used in many industries like cinema, supermarkets, and so on. This project tries to recreate these figures using the reflaction of a laser with two mirrors wich are rotated by motors.

Step 1: Materials
- Laser pointer
- Metallic bottle tops
- Liquid silicone
- Carton box
- Welding wire
- 2 motors (small)
- Soldering paste
Step 2: Preparing the Motor
First, paste the both motors to their respective bases.Then, weld or paste the negative cables to the negative pole of the button.
Step 3: Finishing the Circuit
Weld or paste other cable with the other pole from the button. Then, connect it with the battery. After that, connect directly the positive pole from the motor with the positive pole from the battery.
Step 4: Repeat the Previous Steps
Repeat the previous steps with the other motor, but change the polarity.
Step 5: Creating the Laser Circuit
First of all, roll up a positive cable with a piece of sponge and compress it. Then, put the negative cable above it. Insert it in the back of the laser and try to pin it up. Paste the laser with a wood base. Then, weld or paste both cables with both poles from the button.
Step 6: Pin the Circuit Up
Position all the components and paste all the wooden bases with the box and the buttons with the top of the box.
To make it work, turn on all the buttons and a figure will appear.
If you want to make more images, you have to change the speeds from the motors.
