Turn Your Coffee Cup Into A Theremug

Here’s something fun I saw highlighted at the Califaudio blog – the Theremug, a DIY project that turns your cup of coffee or tea into a theremin, of sorts.

Here’s Kyle McDonald’s explanation of the Theremug:
1 Prepare some tea
2 Expose the L/R leads on an 1/8″ cable
3 Immerse leads in tea
4 Plug cable into audio input
5 Start up max/pd/processing/etc. and average every 735 samples (882 if you’re in Europe/running on 50Hz)
6 Scale value and drive oscillator

(The tea should not be neglected, be sure to drink it once you’re done making noise.)
