I can be such a nerd sometimes

When the power went out on Earthquake Sunday, what did I do? I built a theremin. A theremin is an electronic device that produces a pitch at a frequency proportional to the inverse square of the distance to an antenna. Basically it works by varying the coupled capacitance of the user’s body (i.e., hand) with the antenna capacitance.

I decided to undertake this project because my company is involved with the Lacy Veach Day of Discovery at Punahou School on October 28, 2006. I think this is the 4th or 5th year of the event.

I got this “Minimum Theremin” circuit design from this website:

Art’s Minimum Theremin

I was so proud, that I took the darn thing to work, haha:
