"Indictron" (You might guess that I like to come up with goofy code names for my projects) is a device I use to monitor the status of the continuous integration servers for some projects I've worked on. It's a USB powered grid of LEDs run by an Atmel ATmega88 processor. The device is controlled by a Windows application that queries the build servers for the status of various projects and then sends commands over USB to the AVR chip.
I should take a moment here to say that I am not at liberty to say for what "build projects" I actually used this, so some details or pictures may be altered/redacted.
In full geek regalia:
