DIY external iPhone keyboards get a tad more practical

That 360 Chatpad hack we saw back in November was certainly an impressive enough proof of concept, but if you want to get a bit more typing done with a bit less clutter, you'll no doubt be quite a bit more impressed with this latest mod by the very same Ralf Ackermann. This setup uses a Robotech Bluetooth module that's placed in a modified battery sleeve and connected to an unlocked iPhone (or iPod Touch) which, in turn, communicates with the keyboard using the Bluetooth SPP profile (a VNC server and a few other tricks also come into the picture). Of course, that's still a long ways from an officially supported solution, but if you're looking to give it a go, Ralf is promising to dish out the necessary schematics and source code soon.
