DIY Simple Green Laser Projector

DIY Simple Green Laser Projector

First, you will need a green laser anything 125 mW and above.You also need a diffractive glass that will distribute the green laser beams.You could probably use those cheap diffractive glasses from 3D glasses too.
Second, you will need a plastic epoxy
Third, you need bunch of pipes

You need to drill a hole in the center of the diffractive glass, then epoxy it to the motor. Now, I accidently broke the glass and had to epoxy everything. Just make sure to use a real thin drill and go slow so you don’t make the same mistakes that I did. Then, also epoxy the bottom end of the motor to the 90 degree pipe arm. (Make sure to solder on 2 wires to the motor!).

Build your green laser projector using the pipes and pipe parts sorta like below. Put all the wires through the pipes so it comes out the other end. (Sorry again, I forgot to take pictures of this step.) Then assemble everything. You can fit the green laser through the T-pipe piece. (For the T-pipe piece, I used a bigger size then used electrical tape around the pipes to stabilize it.)
