Make your own wireless NES controller for Wii
Sick of pesky wires and have a PhD-level knowledge of electronic hackery? Then you, my friend, can make your very own wireless NES controller that works on the Wii! You'll need to do some soldering and some serious controller-hacking to get the job done, but if you're game, more power to you. Personally, I'll just have to wait until someone makes up a batch of these and hocks them on eBay. When it comes to soldering, I'd rather just have a sandwich.
