In an attempt to make brewing his small batch beer even more fun than it already is, Android hacker and home brewer Paul Carff created KegDroid, an NFC/RFID enabled smart tap for his home bar. Presenting the device with a MiFare-based RFID/NFC compatible tag will cause it to authenticate the user and pull up their preferences on an Android tablet. Users then have the choice and size of beer that’s delivered by an Arduino, a couple of solenoids, and some flow sensors. Sure sounds like my kind of Internet of things. [via /.]
