I have an Apple Pro Mouse that stopped working. I thought I would tear it apart to see how it worked before I threw it away, at the very least I could salvage the LED from it. As I held it in my hand I realized it was the right size and shape to become a belt buckle. With it's two-layer construction, the design could be custom and interchangeable.
Step 1: Dead mouse
Dead Apple ProMouse. In the background you can see the logitech mouse i found on the sidewalk that made a great replacement.
Step 2: Dismantle
Pry the mouse apart with a small screw driver. Some of it was glued together, so I used an x-acto knife to cut the seams.
Step 3: Custom Image
Here is where you can install your own personal image. For this one, I dug through a pile of stickers I've been saving and found this image of a bird on a powerline (2000 x-games)
I layed the top portion of the mouse directly on top of the graphic. Then I used an x-acto knife to trim it to shape.
Step 4: Apply the design
I applied the sticker, and burnished it tightly around the edges. Other options at this point would include, painting the piece, or applying custom printed images with adhesive..... or leaving it as-is so you can show the world how much you love Apple while keeping your pants up.
Step 5: Drill the tounge hole
Drill a hole 3/16" in diameter in the bottom plate, at the side that is closer to the thumb grip.
Step 6: Tonge and hinge
Use a piece of wire (I used a coat hanger) as the tonge and the pivot connection to the belt. The tounge sticks out throught the hole we made in the last step. The wire then is bent into a rectangular loop, which will be the means of attaching it to the belt.
