I Saw Her Standing Theremin [Open Theramin part 1]

I am going to need some truly weird sounds to mix into the soundscape for the road animation - so I have literally no choice but to build a theremin. My hands are tied (which may make playing the theremin difficult).

Named after its' inventor Leon Theremin, the theremin is the most science-fiction-y of all instruments, famous for being used in movies such as The Day The Earth Stood Still and Mars Attacks, and also famous for not being used in the Star Trek theme tune (it's actually sung by a soprano) or the Doctor Who theme tune (they used pretty much every possible sound generator except a theremin).

For this DIY project I'm using the Arduino-based Open Theremin v3 design by Urs Gaudenz. You can read about the history of this interesting project, find out more about Leon Theremin and order your own kit here.

 The kit includes an integrated theremin circuit board, connecting pins, switches and LEDs (the Arduino and USB cable were purchased separately) ...

...and also some of these things.

You just need a few extras - the Arduino itself, some kind of stand e.g. a camera tripod, some earthing wire, and either a decent pair of headphones or a speaker and a set of very, very tolerant family members and neighbours.

One round of dodgy soldering later:

My evil plan worked! Now all I have to do is learn to play it...
