Soda Can Theremin Video

We recently published a video about a simple Theremin built using the Analog Discovery and the Analog Parts Kit. A Theremin is an electronic musical instrument which essentially turns the user into a variable capacitor. The user can then adjust the frequency of the sound produced by the instrument by moving their hand in relation to an antenna. As the distance to the antenna changes, the capacitance also changes, thus changing the signal frequency. In the Theremin showcased in this video, a recycled soda can is used as the antenna.

 

The soda can Theremin designed and built by William Wadkins.

This is a great project for anyone learning analog circuit design because a variety of components and signal types are used. By following the instructable for this project, you can re-produce the Theremin; however, if you want to learn more about the concepts used by the circuit, check out Digilent’s Learn site. There is also a great deal of educational material on our YouTube channel, like this playlist about analog circuit design and analysis.

 

Check out the video and let us know if you would like to learn more about this or any of our other projects.
