So I was thinking about using a beaglebone to integrate features into my ferret cage like an led marquee, background sound, and possibly a webcam. For those who do not know, a beaglebone black is a $45 computer that can fit into an altoids tin and has a lot of generic inputs and outputs. Well, while surfing the web, I found an article on adafruit about some one who created a "gameboy" from a beaglebone and a custom cape he created.
I thought I'd share it here for you to enjoy.
