Introduction: Make Your Own Simple Theremin
In this project I will show you how the electronic instrument Theremin works and how we can create a simple version of it with the help of 2 ICs and only a few complementary components. Along the way we will talk about oscillator types, body capacitance and much more. So let's get started!
Step 1: Watch the Video!
The video gives you all the information you need to create your own simple theremin. In the next steps though I will present you some additional information to make recreating this project even easier.
Step 2: Order Your Components!
