HOWTO: Build a low cost Stepper Motor organ!

Since the very first time I saw a video of someone using stepper motors as a musical instument I wanted to build this for my own. Unfortunatly I found no infomration on the internet on how they build this besides that most of them were using an Arduino.

A few weeks ago I decided to get myself an Arduino Uno, a CNC Shield V3 the stepper motors and some miscellaneous stuff and build it on my own. Finally it is now working extremly well (See the videos below) and because I don't want others to wonder how to build it I'm publishing this tutorial on How To do it.

I know that Thingiverse may not be the perfect platform for this, but since it is loosly connected to 3D printing I post it here. Have fun!
