I think with a better amplifier setup I can get a spirograph type output from it, at the moment one coil is bouncing, it is either doing that or off..... more experimentation to be done me thinks.
I ran it straight from the speaker outputs tonight, you can indeed get spiro patterns ...But with no amplifier...(parts for that on the way courtesy of SenKat)....the output is very small, so not worth filming at the moment but looking to be feasable.
