Back in 2008, Daniel Jansson designed a concept mouse based on the NES controller. Instructables member champx turned the concept into reality and made a wireless mouse that actually uses parts from an NES controller.
As you can see, the champx’s mouse doesn’t look exactly the same as what Jansson imagined, nor is it as polished, but it’s still pretty awesome. As you might expect, champx used a couple of NES controller buttons for the left- and right-click mouse buttons, and a NES controller D-pad as a scroll wheel. Champx used the base of the original mouse, then made the new body out of Makrolon, a brand of polycarbonate. Next, imagine a montage of champx gluing, hacking, sanding and painting set to the music from Punch Out, and voila!
Head to Instructables to see how champx made the mouse. Surprisingly this is actually his third take on a NES controller mouse. He also posted his other builds on Instructables; his first build is literally the entire NES controller itself used as the body of a mouse.
