Hey folks,
I am working on a synth chassis that has a goat skull mounted on an upholstery spring (like a bobblehead). I am looking for it to have subtle nods that are correlated to what is happening in the music.
My first idea was to do some sort of beat detection and drive a stepper motor with connecting arms between the skull and the chassis but it is really rigid feeling. If I just give it a thunk right now the skull will bob for a minute just with the energy in the spring and I like that fluid motion.
I am wondering if there is something else less ridged that I could use to actuate spring motion? I have a basic understanding on how spring reverbs work, is it realistic to drive some sort of magnetic coil with my sounds and have it create motion? I rather stay within 5 volts, i do not know if I could create enough magnetic flux.
