Beerbot - Twitter + Arduino Beer Vending Machine Hack

Metalworks by Maxus presents: Beerbot — the Arduino-powered, Twitter-activated beer rationing system.

Beerbot uses a Rails app to detect when Maxus staff request a beer on Twitter. Authorised Twitter accounts can Retweet to "approve" the beer request.

Beerbot 1.0 featured a hacked fridge with Arduino+Ethernet Shield connecting to Thingspeak API, powering servo-motors to vend the cans.

Beerbot 2.0 is a portability and stability upgrade. Includes Arduino+WiFi shield to interface with the new mini-vending machine electronics. It was upgraded to run on MQTT language (via Cosm) due to overheads with parsing JSON.
