I'd like to introduce you to the @TeaweetBot - a twitter controlled robotic kettle. The idea is simple. On your way home from a long hard day at work, tweet #PopTheKettleOn to the @TeaweetBot and the kettle is switched on, boiled and ready for you on your return.
Built using a number of open source technologies including Processing to listen to Twitter and Arduino to power the motor. I worked on this as my first foray into making and coding. It received a bunch of love from the press and was featured in Campaign Magazine.
