iPod Modification Ideas
tychver:
Why not just build a battery box with a USB female socket in it? Four AAAs and you could have a 1AH external battery. Although if I'm going away I pack my car charger, I did contemplate doing this. If you were really going to build something like this you would want the largest capacity batteries avaliable.

wouldn't 4@800mAH be more that that?

USB doesn't run off of 1.5 volts (AA/AAA).
Assuming 800mah AAAs:
Four AAA cells in series = 6 volts at 800mah.
Four AAA cells in parallel = 1.5 volts at 3200mah.
reid:
If you do replace the wolfson codec (dac) how could one make it work. Could it be done now that an ipod has rockbox. Someone could come up with the proper settings for new dac? I also thought about possibly ( and tell me if this is stupid) getting an outboard adac to dac using the line out. Is that a really stupid idea or using the best of the best chips you dont have to worry about messing with the internal codec.

Assuming you picked a DAC with a spec sheet, you could just write a dirver for it. The hard part would be actually getting it onto the Ipod's board. You'd probably never find one that was pin compatible.

The line out is analog, so you can't do that. You'd need to use USB, and that would be extremely difficult since we don't have the USB stuff figured out (and no one is even quite sure if its possible though I suspect it is).
