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.<\/p>\n<p>&nbsp;<\/p>\n<figure id=\"attachment_7661\" aria-describedby=\"caption-attachment-7661\" style=\"width: 600px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/digilent.com\/blog\/wp-content\/uploads\/2015\/06\/theremin-thumb-still.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-7661\" src=\"https:\/\/digilent.com\/blog\/wp-content\/uploads\/2015\/06\/theremin-thumb-still-600x338.jpg\" alt=\"The soda can Theremin designed and built by William Wadkins.\" width=\"600\" height=\"338\" srcset=\"https:\/\/digilent.com\/blog\/wp-content\/uploads\/2015\/06\/theremin-thumb-still-600x338.jpg 600w, https:\/\/digilent.com\/blog\/wp-content\/uploads\/2015\/06\/theremin-thumb-still-1024x576.jpg 1024w, https:\/\/digilent.com\/blog\/wp-content\/uploads\/2015\/06\/theremin-thumb-still-225x127.jpg 225w, https:\/\/digilent.com\/blog\/wp-content\/uploads\/2015\/06\/theremin-thumb-still-800x450.jpg 800w, https:\/\/digilent.com\/blog\/wp-content\/uploads\/2015\/06\/theremin-thumb-still-1200x675-cropped.jpg 1200w, https:\/\/digilent.com\/blog\/wp-content\/uploads\/2015\/06\/theremin-thumb-still.jpg 1280w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\" \/><\/a><figcaption id=\"caption-attachment-7661\" class=\"wp-caption-text\">The soda can Theremin designed and built by William Wadkins.<\/figcaption><\/figure>\n<p>&nbsp;<\/p>\n<p>This is a great project for anyone learning analog circuit design because a variety of components and signal types are used.
