OpenTheremin V4 - Build Instructions
The OpenTheremin Version 4 is a Do It Yourself (DIY) theremin that is easy to build and gives you a lot of flexibility to adapt to your own needs and creativity.
All you need to build the newest version of the open source theremin is a screw driver. The Arduino is now built into the design and while still fully compatible to re-program the theremin with the Arduino IDE, there is no more soldering required and the theremin board comes pre-programmed and ready to go.
A solid tripod stand made from milled solid aluminium with a standard 1/4" UNC thread ensures stable mounting on any commercial camera or smartphone stand.
The ingenious system of plug in turning knobs makes for a flush design with pre-mounted potentiometers on the back of the board. New inserts, pre-assembled in the pick-and-place process make mounting the antennas easy. The antenna connections are completely hidden behind the circuit board and give the OpenTheremin its uniquely simple appearance.
