Homemade Laser Projector

Laser projectors send a thin beam of light across a large distance. They can create spectacular effects, but you don't have to go to the store to purchase a laser projector. You can construct a home-made laser projector with a few simple materials.

Things You'll Need

Towel
LED flashlight
Needle nose pliers
AixiZ laser housing
2 conductive pins
Soldering iron
Solder
Bonding glue

Instructions

- 1
  Lay a towel down on a work surface.
- 2
  Remove the batteries from an LED flashlight. Remove the reflector from the flashlight. Take the lens out of the reflector and throw it away.
- 3
  Use needle nose pliers to take the bulb out of the flashlight. Dispose of the bulb.
- 4
  Get an AixiZ laser casing and take it apart so the front and the back are separate. Throw the front part away.
- 5
  Turn on your soldering iron--be careful as it gets quite hot. Put the back part of the AixiZ laser casing on to the towel. You should see a laser diode attached to it.
- 6
  Use the soldering iron to connect the positive and negative with a conductive pin. Allow the solder to cool down.
- 7
  Connect the AixiZ laser casing with the conducive pins to the LED flashlight. Use bonding glue to hold everything in place. Allow the glue to harden.
- 8
  Attach the reflector to the flashlight. Reinstall the batteries and put the battery lid back on.
- 9
  Test the laser projector by switching the flashlight on and aiming it at a wall. Do not point the laser into the eyes or into people's homes.
