Tea cup theremin


Hardware modding can take you to some strange places: sometimes, you think of really useful improvements to your most practical devices. Other times, you turn a cup of tea into a theremin. This is true at least for [Kyle McDonald], who immersed the L/R leads of an 1/8″ cable in a cup of tea, and connected it to a computer running Max/MSP with a special patch. The result is a working, miniature theremin you can drink after you’re done playing. This process should work with any liquid, so feel free to use beer, cola, water, or anything you think will taste better after you’ve run a small charge through it.

    I’m dubious of this… what’s it doing, picking up the 50hz hum? What does the tea have to do with it?

  7. ex-parrot: Yes, the 50/60 Hz mains hum is what’s being capacitively coupled to the tea cup via your hand. Try it yourself by averaging every 765 samples at 44.1 kHz.

    Theramin, or the logic circuits of a Brambleweeny 57 Sub-Meson Brain?
