DIY modules are a great way to get into affordable music making - many professional kits are available as well as thousands of projects online. Here we have an optical theremin featuring a pair of very inexpensive TCRT5000 IR Led/Photo-transistors, 2 NPN transistors and a small number of passive components. It sounds superb and the hour of practice paid off.
The schematic is available at the end of the video, made by MeerCreate who explains: "The main goal of this project was to design a good sounding theremin that was accessible to entry-level hobbyists. I think I succeeded in that".
Certainly did! Considering the amount of components, it sounds and plays superbly well.
