BadgerHack: Synth Add-On Kit
Nick Poole 
Introduction
The BadgerStick that you received by visiting a SparkFun booth at one of the various events we've attended can be hacked to perform a wide variety of tasks. It can even make music, depending on your definition of music.

Follow along with this guide and you'll be making sweet noise in no time!
