i made this over the weekend . it's got 4 motor's with 4 pot's &4 batt's that's it
junk i had on my bench . i have the part's on the way for a 8 motor build with full control speed /forword/rev on each motor . http://www.youtube.com/watch?v=fSevt-ZJPo4
Cool, I always wondered what happens when you add more motors be sure to post that one I remember my first spiro haha it was built from 3 motors I had lying around and a 12V power supply, my only speed control was using my finger to slow down the motors haha.
To the above, the mirror needs to be off set so it wobbles a little. The more off set the bigger the circle it makes.
As for how to offset the mirrors: There are a lot of ways. I used dubblesided tape (or singlesided wrapped around), but thats just for testing. Though, it worked great =) I would imagine some sort of thick glue would do the trick. I'm not too familiar with "international" glue, as I only know norwegian names, but I guess you'll figure something out
ahh.. well i was going to put like 2 inch circle mirrors onto CPU fans.. so what would be the best way to offset the mirrors?

All you need to do is have the mirror at a very slight angle to the fan, something as tiny as 1 degree is fine. I used a big bit of blue tack and stuck a 3cm mirror to some motors. Blue tack worked fine for me, you can adjust the angle easily as well.
Just make sure you use enough blue tack or you might find mirrors flying everywhere.
