Robot Voice Modulator
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).
