I bought a couple of the "star lasers" from a seller on AliExpress a few months ago. Here's a crappy video to show you what the output looks like: Laser2.mp4 I want to mount these in a camera housing out the front of my yard and shine them onto my roof. This should keep the beams away from everyone. What I really needed was a DMX controlled laser, so I have designed a small P-DMX board. It provides the 5.5V DC to run the laser and also controls the rotation motor (speed and direction) as well as turning just the beam on and off. It can also power down the whole laser. Anyway, I've ordered the prototype boards, so once I receive those and write some code for them, I'll post about this project some more.
