For something completely different comes this project by Johannes Hoffman - with his "Tweety" clock. It's a typical cuckoo clock that has been brought into the 21st century with the addition of an Ethernet-enabled Arduino board and a small thermal printer. The sketch monitors a certain twitter feed, and if the username has been mentioned the cuckoo is activated and the information is printed with the small thermal printer.
Three servos are required for the cuckoo process, and all the hardware is easily available. However the entire project can also be a framework for your own twitter-monitoring device if you're not interested in the clock. Either way, visit Johannes' website for the requirements and Arduino sketch. And for more, we're on twitter and Google+, so follow us for news and product updates as well.
When putting together your next Internet-enabled Arduino project - save time, space and money with the Freetronics EtherTen. Apart from being fully Arduino Uno-compatible, it has onboard Ethernet, microSD socket, full USB interface (so you don't need a costly FTDI cable just to upload a sketch!) and supports optional Power-over-Ethernet.
