DIY: Build your own Laser Projector
Do you like laser projects? This is perfect for your weekend projects, you can do on your own with some minor investment going towards laser controller software.
Here’s how the projector works, also check this gallery of the project in making:
The green laser bounces off a mirror then through a green beam splitter, the beam is then separated (The reason for this is later I added a second beam turret projector which did not work well so I removed it and also the beam splitter The Green beam then bounces off a red dichroic filter and into the Scanners. The red laser passes through the red dichroic filter this allows you to mix the two colors into one beam or into dual images if the alignment is off.
(Most all of the video uses the red laser because the green was too bright for the video camera)
Here is some information on my laser system and where you can find the parts.
