Gram Piano Assembly Guide
Introduction
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.
