Hacker Trifecta: iPad, Arduino, kegerator combined in single device

John Boiles, whose extracurricular exploits as an undergraduate at UT Austin brought us iPhone-controlled dance floor lights, R/C cars, and yes, even full-size automobiles, has since moved to San Francisco and scored a job with Yelp. His latest “spare time” project, with the Yelp Engineering crew, is KegMate–a keg-mounted, Arduino-controlled data-logging suite with an iPad-based user interface. Among other features, the system reports and records the keg temperature, tracks which of its registered users is dispensing beer and how much they’ve dispensed, and collects user ratings of whatever brew happens to be on tap. [Thanks, John!]
