when you go to pretty much any electronics store, all of the ipod docks are expensive and usually are pretty simple. with the tennis ball dock, it will only cost you a few pennies and you will have a one of a kind iPod dock (my pictures were made in paint because my digital camera is broken, but as soon as i fix it i will add pictures)

PARTS

tennis ball
screws, or nails, or pieces of wood, whatever you want to use
scissors/knife
iPod (duh)

this is my first instrucable, so please comment and send pictures

Step 1: Carving the Tennis Ball

This is pretty easy, basically just carve a rectangle about the size of the bottom of you ipod into the tennis ball. I used a knife and scissors but you could prbably use anything sharp. remeber this is where you will stick your ipod so make sure the hole for your ipod is not to big or to small

Step 2: Adding the Supports

for this part you will need the four screws. using a pencil or pen, mark the spots where you will put the screws, make sure that it will keep the dock from tipping when you put the iPod in it. once you have the spots marked, put the screws in the holes. You might need to use a knife to put the four holes in the ball.

Step 3: Adding the Hole for the Charger Cord

this is the very last step, and it's probably the easiest. Just cut a small slit in the back for the charger cord, or for a speaker cord. Using the knife, cut the slit and make sure the cord will be able to fit through. Once you have done this, you will be done with your ipod dock.
