Sevy machined a custom plastic HDPE electronics housing. He used a bandsaw to cut the panels and a mill to cut out the opening for the display. It is held together with L-brackets and epoxy from the inside. This makes the box appear slick with no sign of fasteners.

Sevy wired up the LCD (Liquid Crystal Display) to a micro-controller via a breadboard. He then tested the LCD with Arduino code to learn the functions. This example shows testing of the scrolling feature.

This video is an explanation from Sevy and Ryan on how the whole system works.
