iTrip mini universal mod
posted May 5th 2006 11:00am by Eliotfiled under: ipod hacks
[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.
Nice hack and great info.
From TFA: “Currently the iTrip has to be powered by my sisters iPod to function but in the next step I will construct a 3.3v regulated power supply using some free samples from my good friends at T.I! Also this will give me some time to design or think of a good way of containing the Power Supply, Batteries and iTrip.”
I’m *really* looking forward to this part of the tutorial, provided it gets written. The only thing keeping a nano+iTrip from being a good in-car solution is that the batteries are probably aren’t up to task for a long car rides (or switching to mass transit after a short one). So an acessory port adapter for that +3.3V, would really be the icing on the cake.
