For $8, you can have a wireless Wii sensor bar

The fine folks at avsforums has a post on what you need to get the Wii sensor bar to be wireless. It all comes down to some stripping and crimping of parts totaling $8 from your local Radio Shack. I suggest using a replacement one from Nintendo for $10 to do this little trick in case you mess it up.
