This is one of my favorite projects yet! I flip a boring plastic TV remote into a two-toned wooden beef stick. And what did I use for a battery cover? Another remote of course! It's two remotes in one held together with magnets!
If you have a flatbed scanner that's the preferred way of doing this. If not a camera and some grid paper will do. You can use the grid to fix the skewing and perspective in Adobe Illustrator.
