iPhone Keyboard, Sort Of
Not quite ready for mass production or very easy to build, but if you really really really have a problem typing on your iPhone or iPod Touch you can build one of these “keyboard for your iphone” adapters.
By using an Arduino, a 9 volt battery, an iPhone breakout board, and a PS/2 keyboard, Ben Kurts built this keyboard adapter for his iPhone. The Arduino reads the keyboard input and converts it to a serial signal which is then pulled in by the iPhone via VNC. Not exactly a clean way to get it done but you can be rest assured that you’ll be one of the few people around who has an external keyboard for his/her iPhone or Touch.
