What the hell is a luminiferous theremin?

The Theremin The Theremin was created by Leon Theremin (Lev Sergeyevich Termen) around October 1920 after noticing that a high frequency oscillators would change their frequency when a hand (or other object) was brought close to them. He added a circuit to make this change audible as a change in pitch of audio tone. After […]

After demonstrating his ability to play notes and music on this device that he initially called the etherphone but over time became to be known as a Theremin. The Theremin works as the proximity of the users hand changes the frequency of the oscillator feeding the ariel by adding capacitance to the circuit. The problem with this way of detecting the position of the users hands is that the oscillators need to be calibrated each time before use, and have a tendency to drift in frequency when the device is moved, or with changes in temperature and/or humidity.
