The Kegbot At DefCon 05
One the coolest projects I’ve seen so far at DEFCON was the kegbot, a linux based keg that dispenses beer as long as you have an iButton key. The system keeps track of who you are, how much you’re drinking and in team mode- where you rank. the Kegbot crew built and deployed a kegbot on site at DEFCON, we were lucky enough to get there and document the building of it!
