This is a project developed during our ”Taller de inventos” (August Build Night), sponsored by Instructables and Jameco. You can read more about the event over here.

Here we’ll show you how to make a light theremin that has a

Here's a video of the theremin

The first step of this instructable is printing the PCB. You'll find attached the necessary PDFs.

Since this task excedes our instructable, feel free to follow these instructables instead:
- How to make the PCB board (available in Spanish)
- PCB making guide

We suggest you mark where every component goes with a sharpie marker on the rear side of the PCB.
