Is it possible to create a tattoo machine controller with arduino? Tattoo machines usually work between 5-13vdc at less than 1 amp. Right now most machines operate by opening and closing a circuit containing two electromagnets to pull the armature bar down (pushing the needle down) then breaking the circuit, releasing the needle/bar.
I'd be interested in creating something to either draw it's current from a deep cycle marine 12v allowing me to adjust the voltage or more preferably, something that would allow me to take either 120vac or 12vdc and convert it to an appropriate voltage that would allow me to turn on and off the electromagnetic coils using the arduino.
