We've seen theremin mod
after theremin mod
, but those seeking that distinct sci-fi sound without the physical labor or hefty price tag haven't had much of an outlet until now. Meet Beep-It, a $35 analog optical theremin that sports a simple on / off switch, volume control, one quarter-inch jack, and light sensitive resistor to make you the master of that otherworldly sound. According to its creator, Michael Una
, the little sonic music maker started off as yet another mod -- a "single-oscillator square wave theremin" in a petri dish -- back in 2008, and underwent a number of incarnations before getting the wood grain treatment you see here. Beep-It is now available at select retailers or direct from the company's website -- then again, we suppose you could hire Bobby McFerrin to do the same thing. Trippy demo after the jump.
