  1. Slightly easier to build... by Darius+Jedburgh · · Score: 4, Interesting

    ...I just built myself a theremin based partly on this. It transmits a pair of RF signals at around 1MHz. As you move your hand around it varies the inductance of the coils so that the coils transmit at slightly different frequencies. As a result you get a signal at the average of the two frequencies modulated by the beat frequency. Tune an AM receiver to the average frequency and you get to listen to just the beats. It took a couple of hours to build. (The project I linked to above has an AM receiver built into the circuit but I didn't bother with that as I already had a spare radio.)

    And in tomorrow news :
    Jean-Michel Jarre is claiming prior art...
