In the next couple of pages, we’re going to show you how to build your own OpenChord V1.
Basic Steps
To build a V1, there are basically 5 steps you need to do. Each step is covered in detail below, but the steps are briefly:
1: Electrically insulate the strings
2: Attach wires to the frets
3: Attach wires to the strings
4: Install the extra buttons
5: Connect and install the circuit board
Theory
The V1 operates by sending a very small electric charge through the strings and frets to determine where the strings are being held against frets. These connections act like switches, and the the microcontroller is able to read these connections, interpret them, and output the appropriate button information to the console.
