Judging by the time we spent with the "candle fix" not really (although it might take recalibration and you also have to contend with distance from bar/angle of the remote- your basic field of vision idea).

Secondly if you are making something can you not just stick two sets on two sets of PCB/stripboard (or indeed float them off the breadboard) to see how it works for you?

 

Step 1: power on Wii with official sensor bar

Step 2: look at sensor bar with Cell phone or webcam. You will see purple/blue lights on the screen.

Step 3: measure LED space.

Step 4: ????

Step 5: Profit!

 

We've just had the living room done up, TV is now on the wall and all cables are hidden (scarts/HDMI and wii AV channelled into the wall, but not the sensor bar cable) so there is nowhere for the sensor bar to fix to.

I wanted to make 2 seperate led units and have made 2 holders for the LED units that hook over the top of the TV. TV is 42" widescreen and actual width is approx 46", so the LED's would potentially be approx 40"-44" apart.

The solution for your setup. Never used them myself, but they seem viable.

 

yeah i'm sure every1 wants wax dripping down their tv

 

I believe the wiimote only detects movement from a light it detects. This displacement is then sent wireless to the Wii, where it interprets the displacement as movement.

The sensor bar doesn't do anything other than light up its lights. The wiimote is sensitive to the light emitted by candles I guess too :/

 

Re candles: hot objects (like a flame on a candle) generate infra red radiation much like the sensor bar (which has a bunch of infra red LEDs* in it) and that is what you wii picks up.


*if you want to see them point your mobile phone/some other camera at them and they will be visible.

 

The problem is there is nothing for the sensor bar to rest on. There is no shelf etc below the TV, just a TV on the wall. The cable are channeled into the wall and go into a hidden cupboard that is in an alcove at the side of the chimney breast where the wii, HDD, BlueRay etc are kept.

Sorted it now anyway. I can confirm that the LED's can be 43.5" apart (although this is not their limit, just how far apart mine are)
