Parts List:
1. Ipod emergency charger link
(note: the one I used cost 5 bucks at a store called "5 and below", if we could just find somewhere to get the tip, because that is all we need, for a buck then that would be ideal.)
-Dealextreme.com has this one which I think would work as well. Under 5 bucks and FREE SHIPPING!
2. Radio Shack "AAA" battery holder link
3. Soldering Iron
(note: not requires you could just twist the wires together and tape it over)
4. 4 AAA rechargeable batteries
(note: can be had at the bankrupt circuit city for 4 bucks!)
5. A suction cup
(note: picked mine up at the grocery store)
