Stomp Box Design
BeagleBoard and Arduino
The main components of the stomp box are the BeagleBoard and an Arduino. A breadboard was attached to a plastic plate to accomodate the Arduino and its associated connections.

The Arduino connects to the BeagleBoard via USB.
Input / Output
The BeagleBoard communicates with the computer via LAN. The guitar and headphones/speaker connect through the Guitar Link USB adapter.
Audio input/output via 1/4" jacks and USB. Computer connection via LAN.
The physical user interface (UI) elements of the stomop box will be two knobs (volume and tone), one button (toggle effect on/off), and an accelerometer (trigger effect). Here we see the knobs and buttons after soldering.
Build Process
Here are a few shots during the build process. The UI elements (knobs, button, and accelerometer) are being installed.

The accelerometer (shown in hand) will be used to trigger the wah-wah effect.
