My friend asked me to make him an ipod dock/charger, and this is what happened. I think that it turned out pretty well, despite being made from parts that were found laying around the house.
Step 1: Get your stuff together...
First of all, go around the house scrounging old electronics and stuff. You'll also need to "modify" a ziplock, so use one that you don't need.
2 small speakers
A cable to connect them to the iPod
Square ziploc (pictured)
An iPod to try it out on
If you make your own cables - wire strippers, electric tape
Suggested - A hole-cutter attatchment for a drill (this is just to make things easier; a sharpie would work too).
