"Are you a musician (or just someone who loves making noise)? Like crazy noisemakers? Want to drive your parents/spouse/kids/dog/cat crazy? Like any product that involves a Big Red Button? You'll love the Beep-it Optical Theremin. It is a hand-held, rectangular device that features a Big Red Button, a volume knob, a 1/4" jack, and a light sensitive resistor. Simply put in a 9 volt battery and you'll be ready to play.

As an optical theremin, it outputs a square wave whose pitch is controlled by the amount of light striking a photoresistor. You control the pitch by casting shadows over the light sensor or by pointing it toward or away from a light source. Using a flashing light can induce a cool oscillating effect. It's fun for amateur noisemakers, but powerful enough for professionals working in experimental, hip-hop, electronic, sample-heavy, and indie rock genres. It is simple to use and powerful enough to appeal to any musician to use in a live set or recording or sampling session.
