Kegbot Kegerator Project - Monitor keg volume & control access.

"Welcome to Kegbot! Kegerator monitor and access control. Kegbot is a free, open-source project to turn your beer kegerator into a computerized drink tracker. With Kegbot and our Arduino firmware, you can: Monitor exactly how much beer is left in your kegs and track the temperature; Record the volume of each and every pour; Set up user accounts to track who is drinking, how much, and all sorts of other nutty statistics; Use special keys (tokens, RFID tags, barcodes) to authenticate your kegerator users; Control access to your taps (with special valve hardware) to prevent unauthorized pours; ... and many other crazy things!
