More iBus circuits – iPod control using MFSW
After designing the HKenabler circuit, I prototyped a similar circuit for my friend Gavin (GadgetGav on MINI2). He has an iPod installed in his car using the Belkin kit (reviewed last year on MotoringFile). This kit provides power & sound, but no control.
So we built a simple circuit that monitors the steering wheel MFSW buttons (track up/down and the unused middle button) and puts out signals when the buttons are pressed; these signals are then wired into an iPod remote to simulate button presses. This might sound complicated but it is inexpensive and effective:
(UPDATE: The above pic is *during* the install – afterwards all this disappears and the car looks tidy again!)
The result allows Gavin to control his iPod track up/down using the steering wheel buttons; in addition the middle button now does play/pause on the iPod:
I don’t have any plans at the moment to make more of this circuit – if there was reasonable interest (10 or more people) something could be done. Realise however that the iPod remote is sacrificed by this install (although I believe a replacement is not too expensive).
