Gram Piano Assembly Guide
This Tutorial is Retired!
This tutorial covers concepts or technologies that are no longer current. It's still here for you to read and enjoy, but may not be as useful as our newest tutorials.
The Gram Piano is a through-hole soldering kit that transforms from a pile of hardware into a tiny piano, ready for the playing. Once built, you can play an octave worth of notes using the capacitive touch keys. The pre-installed software also lets you switch between three octaves using a potentiometer and play a melody with the press of a button. Building and playing with this kit will teach you various skills related to soldering, electronics, music, and programming.
Covered in This Tutorial
This guide will explain the assembly process, the gram piano's default functionality, and will provide an overview of the pre-installed software. After building and playing with the board's default settings, you can customize your board to your liking by diving into the source code.
