[josh mason] is in the process of converting his iTrip mini FM transmitter (cache) so that it will work with any device. The iTrip uses the iPod’s accessory port for power and control. The acc. port is what Apple used before settling on a standard dock connector. After he cracked open the iTrip, Josh compared it to an earlier hack we featured and noticed that the wiring was backwards which explains why the acc. port devices won’t work on different generations. He’s got a new headphone jack attached but still needs to construct a power supply. If he wasn’t making the device universal, he could get 3.3V out of his nano’s dock port.
