Keep in mind that I am a complete noob and haven't even built my C Beam machine yet. I do believe that there are Bluetooth controllers out there or possibly it could be run off of a Raspberry Pi wifi setup. The mechanics of it should be fairly easy seeing that is should only be on an X-Y axis. OR you could put a funky Z axis setup in it as well that brings it forward a smidge once it is in the up position. Sounds like a cool project!
