Once again it is always interesting to see how people connect forms of technology from two different centuries. The people at tinkerlog have done exactly this by using an old electric typewriter, Arduino with ethernet and some analysis to create a typewriter that prints out incoming tweets. On the surface it seems complicated, but with a few hours of time anyone could do it. See the results in this short video:
Now the search is on for used electric typewriters on eBay... but to get a project like this moving you'll need an Arduino board with Ethernet. Our Freetronics EtherTen orEtherMega boards solve this part nicely - complete Arduino-compatible boards with onboard Ethernet, microSD card and optional POE support:
