Introduction: Make Your Own Simple Theremin

Picture of 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!

Watch a bit of Star Trek the origional series, the Theramin is used in the intro music.

Sounds like a theremin, but it wasn't.

How hard would it be to add a circuit to allow it to have a volume antenna as well as the note? Thanks

Chrisf301 (author)Chrisf3012017-11-18

OH, but great project!!!!!!! Sorry I forgot to add that.

what is a Theremin?

HeyBeck (author)JohnC4302017-11-15









View all

The theremin is an electronic musical instrument controlled without physical contact by the thereminist. It is named after the Westernized name of its Soviet inventor, Léon Theremin, who patented the device in 1928. Wikipedia

oh yeah, after asking that question i went on to watch for the next few hours of demos on YT and there were plenty. thanks for explaining.

Hi Great Scott;

The problem with this and many other simple Theremins is they describe only half of the Real Theremin.

A Real Theremin has basically 2 control antenna systems.

1. One is for the pitch.

2. The second is for the volume.

Yours only has the pitch antenna.

There is a volume knob

BennyOne (author)redrok2017-11-14

If you watch the video he explains the logic behind removing the volume antenna in order to simplify the circuits. Its a pretty slick workaround.

You have excellent workmanship. It's being German isn't it?

Mark 42 (author)PirateKittyK2017-11-14

Deutsche qualität?

Very nice project! Thanks.
