I just saw this over at Engadget
Build your own IPod docking stationIf you haven't throw down for one of the bazillion iPod docks out there, you may have considered just making your own.
If you're a bit short on cash, or just admire your own handiwork, be sure to keep reading for an internal view, and then hit up the read link to peep a full gallery of construction photos so you don't screw yours up.
I don't have an iPod myself so this particular docking station won't work, but methinks the concept and technique is extremely flexible and can be adapted to my favorite portable media station quite easily.
btw, they seem to have gotten it from digg...
