The Wii sensor bar is nothing more than a few IR LEDs, this mod lets you convert an ordinary TV Remote Control into a Wii Sensor Bar. Simply open the old remote and drill a few holes for the IR LEDs. If the remote comes with two LEDs you are in luck, if not you may have to buy a few new IR LEDs. Disconnect the existing battery connection to the remote control circuit and connect it to the mounted LEDs. You should select a current limiting resistor that will prevent the LEDs from being over driven and having a short life. To select the resistor value use an online LED resistor calculator. Now that you have a unique sensor bar invite over some friends and have them wonder where your sensor bar is.
