The NerdKits Theremin Halloween Costume is about as nerdy as it gets – a DIY kit that lets you turn yourself into a human theremin.

This video goes over the design and ideas behind the NerdKits 2010 Halloween costume: the Human Theremin. The costume features two homebuilt infrared distance sensors mounted on the wrists.

Someone wishing to “play” your costume can move his or her hands up and down above the distance sensors. One hand controls the pitch of the note, and the other controls the volume. The sound is emitted from a piezoelectric buzzer mounted on the breadboard, worn around the neck.

If you’re planning a electronic-music related Halloween costume, let us know!
