N900 Rolodex Machine

One part new tech combined with another part old school and you've got the N900 Rolodex machine that takes advantage of the Bluetooth capabilities of the Nokia device to track exactly which contact card is being displayed. Just touch the screen once you've found your contact to call...

An Arduino connected to the Rolodex© detects the position of the wheel and sends that information over Bluetooth to the N900. Each position indicates a specific contact. A Python script receives the incoming information and uses the xtst library to emulate the key presses and screen touches that would be necessary to view that contact and, when you touch the screen of the phone, to place a call.

A few other rethinking of old school devices over at Tinker.it.
