Materials you need:
Magnet (flat, but stronger than a fridge magnet)
small box (at least 3 inches high for the cord to fit)
Droid AC power cord
razor or sharp knife
Cut 2 slits in the top edge of the box about 4 and 3/8 inches apart. Make the slots about an inch on top and an inch down the side.
Fold in the section you cut ( see photo)
Cut in a 1/4 th inch slot for the bottom lip of the phone.
Tape a magnet (as shown) to the box. Tape it about 1 and a half to 2 inches in from the left slit you made in the box. (Test magnet location and polarity before taping)
Place phone in the dock to make sure the Media Center screen shows up.
Measure and cut out the hole for the power cord.
Now your dock is ready! Use a USB cord extension if you need to reach the outlet.
Decorate to your desired taste.
