We have introduced many game controller inspired gadgets, but if you want to make something by yourself, the NES controller styled wireless mouse may be more suitable for you.
Champx, and member of instructables created the pretty awesome computer mouse with a classic NES controller and a wireless mouse. As we can see from the images, the iconic mouse buttons have been replaced by two red buttons on the game controller, and the traditional mouse wheel has also changed to the D-pad and just positioned on the side of the old-school casing, of course, you only use the buttons and D-pad to control your cursor instead of Super Mario. The maker has released the detailed steps. If you want also to modify your NES controller into a wireless mouse, jump to champx’s instructables page for more details.
