FM transmitter made out of different things...Possible?

Hey guys...I need you to point me into the right direction...
I am trying to make an fm transmitter which i can plug into my mp3 player allowing me to listen to it walking around through another mp3 player (which has a radio)....
I have different things which may work but the problem is that i have no idea where to start...
1) i had a wireless FM transmitter but it stopped working...

Having all these three things... it must be possible to build a transmitter or get the first one working??

Buy one off the shelf, thay are only like $20-$30. Look at "Belkin Tunecast II"or the like. Andy
