This is a simple to build device that converts your own human voice into a superior robot voice. It also includes a number of sweet features like an audio-in jack so that you can plug in all of your favorite instruments, microphones and music players, a vibrato mode and awesome pitch shifting buttons. It can be shifted two whole octaves in either direction. This provides for endless hours of fun (at the expense of everyone around you).
