The Wireless Wii Sensor Bar

[teddy_san]

aqui dejo un articulillo en ingles de como hacerte un sensor para la tele de forma casera, por si se te rompe el tuyo y no tienes pasta pero si maña para solucionar el problema. Esta en ingles, asi qeu como de costumbre, si a alguien le interesa de verdad, se lo traduzo sin problemas, aunque es muy sencillito de entender:


Parts ListQuantity
Description
1
Friend to motivate you and design everything
2
project boxes
2
small bread boards
2
10k Ohm potentiometers (Waaay overkill. Do your math first)
4
High output IR LED's
4
Led holders
1
AC to DC converter, 6V, 300mA.
1
Power connector
Couple of feet
Dual strand wire

I put two LEDs and a pot in series in each project box and connected the project boxes to the power supply via the wire. I set the resistance of each potentiometer at 60 Ohms, and the LEDs have a 1.2V drop across them. The circuit simply looks like this:

6V
|
+---/\/\/\----|>|----|>|---GND
|
+---/\/\/\----|>|----|>|---GND

This probably seems very complicated but it really isn't.

Basics

The Wii sensor bar is merely IR LED's connected to the system for power. There is no information being sent to the system!!! SO, if we connect a couple ( 2 or more) IR LED's to a power source (batteries) we will have a wireless Wii Sensor Bar. The Wii controller has receptors to pick up the IR signal and triangulate the controllers position. This is not a new idea but they Nintendo has been one of the first to adapt it to a gaming console.

So here are some instructions on how someone else made the wireless sensor bar:

With just a perf board, some wires, a bit of soldering, 4 AA batteries, and 4 IR LEDs, I was able to make this:



Yes, it's ugly. Yes, it's ghetto. But, it is a wireless, battery-powered Wii Sensor Bar. And it works.

First, I measured the distance between the middle of the left set of LEDs on the Nintendo sensor bar to the middle of the right set. That came out to be 7 1/2 inches. It wasn't a perfect measurement, but since the Wiimote triangulates the distance, it's accurate enough. Soldering wire from the positive side of the battery holder to a switch, the switch to the positive end of one of the IR LEDs, then to the next, to the next, to the next, and then back to the battery terminal, it was easily completed.





Placed on top of my TV showed that it was a success... the Mii plaza, the Wii menus, Wii sports, and Zelda all worked and moved just as well as it had with Nintendo's stock sensor bar. There is no need for a wireless transmitter or an extension cord. Just unplug Nintendo's stock bar, put your homebrew wireless Wii sensor bar in place, and you're good to go.

And your Done!!!
