My commute seems to get longer each morning so I just can't help but trying to think of ways to make it better. I use a cassette adapter to hook my iPod into my car stereo. My car has built in controls for the stereo on the steering wheel, but it's frustrating that I don't have THOSE controls hooked up to the iPod other than the master volume. As far as I can tell the fuax cassette spins as it plays for no real reason other than to fool the stereo that it really is playing a tape. Why not take advantage of that opportunity and have mechanical feedback converted to remote signals to the audio device. The tape FW and RW could be hooked up to next and previous track and stopping the tape should be pause/stop the device. The last one would be especially neat because then I would not have to worry about pausing the iPod when you make stops in your car and it would just resume when the tape started playing again.
