I would like to know how make my own iTrip. I could buy one but this would be waaay cooler.

An iTrip is a type of FM radio transmitter. While it might be a relatively intermediate level project to make one, the one you'd make would have only one channel and perhaps not have the quality and range you'd expect/want.
While not impossible, a commercial one for about £10 would probably suit you a lot better!
