build your own ipod battery back-up?

I was looking at this, and I thought to myself, that all it does is run off a couple AA batteries. Would it be possible to create my own? I couldnt find anywhere what the voltage an ipod runs off of, but I bet someone here knows. thanks PS: I know it will probably void the warranty

Heres a good one, although it is difficult to build...
