DIY Help - Turning Audio Signals Into Art - AKA amplifier signals into a Motor and...(To be Determined) Check out the full project Hello All:Background - Skip down to next bolded header if you don't want to read:I posted here a few weeks ago but wasn't far enough along to ask a specific enough question so it got removed.I am trying to represent audio signals in an artistic fashion ideally the end result being some sort of painted or drawn design being placed on paper or canvas.The input mechanism is not fully worked out I thought about making a miniature "guitar" with three strings tuned to a chord and three separate pickups and mini amplifiers. The 3 signals would be fed to 3 "mechanisms" which would apply different colored patterns (representative of their respective wave amplitudes) to a canvas.I may end up just hooking it up to a regular guitar or even an iPod.In any case my question is as follows:After building a mini amplifier I have run it through a variety of motors of varying voltages. My goal was to have the motor spin in an "intimate" fashion representative of the original signal being run through the amplifier so that I could ultimately hook the axle up to some sort of mechanism that would execute the application of drawing or paint.  I would welcome advice on this front as well as I am not sure yet and haven't gotten the first step completed. Specifically I wanted to use the motor to apply paint but it might be hard to get paint to accurately represent a signal or song "pattern" in a way at all reminiscent to an oscilloscope. Of course it need not be as precise.My main question relates to the motor itself. It seems that I need to strike the perfect balance with the motor parameters. Specifically if the motor voltage required for full throttle is too low the motor just spins normally with no perceptible wave patters. My Electrical Engineer friend described this phenomena as pulse wave modulation.Anyway on the other hand I was able to get it balanced with one of my motors (which is probably not powerful enough to power anything that could complete the objective) in a way that it ended up "pulsing" reliably in a fashion that mirrored the given song I played through it.Another friend recommended a low pass filter which I am somewhat familiar with to clean up the signal. He said it could be built with a capacitor and resistor but I have to research more unless anyone here has any suggestions.Hopefully these bolded questions are specific enough but knowing the parameters of the project how can I arrange an amplifier to power a motor in a fashion that would accurately depict the given audio signal I run through it mechanically?Any ancillary advice will be welcomed as I am approaching a stalemate.
