Howto build a custom Wii motion sensor.

Parts, what's essential

4 x Infrared 5MM LEDs (Radio Shack # 2760143)

1 x 15 ohm 1/2 watt resistor (Radio Shack # 2711102)

1 x Battery Holder for 4 AAA (Radio Shack # 2700413)

4 x AAA battery
Small gauge electrical wire (at least 7 1/2")

Parts - what is recommended:

2 x Project Enclosure (3"x2"x1") (Radio Shack # 2701801)

Housing for your device.
1/4" drill bit
Drill holes in the housing for the LEDs and wire.

1 x Package of 5 LED Snap-Holders (Radio Shack # 2760079)
Keeps the LEDs in place.

1 x SPST Submini Toggle Switch (Radio Shack # 2750612)
Turn it on and off.

Four small cable ties
Place on either sides of the wire where it goes through the hole and trim. Keeps the wires from pulling out.

My design consists of two IR emitters connected by a single piece of wire in a series circuit. I left the battery holder on the outside to make it easier to change the batteries.

When you build your own and you're finished soldering it together, put the batteries in, take it in a dark room and flip the switch. The LEDs will have a very faint, flickering red glow. Infrared is beyond the range human sight, but there's a little bleed-through into the visual frequencies. Some cameras with will be able to pick it up as a greenish glow. To use the emitters, turn the device on and place it on a level surface with about 6-7 inches between the two inner LEDs.

I built the wireless sensor bar, brought it over to the theater and tested it on a regular television. Fortunately, it worked! After the patrons left, we hooked the Wii up to the data projector and house sound, put in Wii Sports, and brought the controllers and the wireless sensor bar downstairs. We set the emitters on the backs of two chairs and stood a few rows back. The wireless range of the controllers was great enough to work! We suffered no technical glitches from the distance; we could even play up on stage, craning our necks up at the gigantic image, immersing ourselves in the game.

In conclusion, there's more than one way one can Wii, and sometimes, size does matter.
