NEW! http://www.youtube.com/watch?v=6hjXGHyHjvI NEW!* A home-made replica of Potato GLaDOS from Portal 2. Constructed using a soldering iron holder, a few nails, some wire, a coat hanger, switch, yellow LED, and two hidden batteries. Sorry, technology can't quite run on potato power, yet. For those curious it is also a working potato battery, capable of generating .438 volts.
