Although I later purchased a Lanling laser show, I first decided to make a spiro device.

All three fan/mirrors are independently controlled using a front bay standard computer fan controller. I put in the cheapest PSU I could find. It's like a 380 watt supply but is really only suppling something like 10 watts max.

The short yellow wire on the connector is to let the PSU run in test mode without having a motherboard connected. The laser is an EnVee 80 just sitting in place.

nice work!! ;) ya i used to have a 3 mirror 10mw green laser show, but i sold it for my RGY from lanling. 3 mirrors can get you some pretty wacky patterns!
 
Nice! The second to last picture is with one fan running I assume, the last one, is that 2 or 3 fans running?

Any crafts store should have them. I got a ton from the store and the smallest being the size of a finger print.
 
man those are some truly awsome patterns, I particularly like the first and second to last, keep up the good work.
