Hello every one I recently made a 2 motor spiro with PWM speed control. This thing took me about a day to make but Im pretty happy with it.

I used cut up hard drive platters as FS mirrors and the PWM circuit was based off the 555 timer IC

Very nice, spiros are very entertaining. Adding a third motor will create some pretty wicked patterns
