Other / Building a IR Array
« on: February 07, 2008, 01:30:00 AM »

I want to build a IR array for the VR experiments; where the Wiimote tracks IR from the reflective tapes paste on the fingers.

I've got a few questions:

1. How many IR LEDs are required?
I want to use if on everything from a laptop screen, PC LCD screen to a projection TV, and LCD TV

2. Do you know the exact wavelength of the IR that wiimote is sensitive?
I recently bought a bunch of IR LEDs that emit a detectable red glow when powered. These are unlike some IR LED I had earlier that has no detectable output seen by the naked eye. I find that the wiimote is less sensitive to the new batch of IR LED that emit the red glow.

3. Do i need a large spread angle?
Do I need to flood that whole area with IR or just a small angle will do?

Thanks and hope to hear some input.

Hey, with Wiimote having 2nd/3rd/4th life as a PC whiteboard, VR, etc tool, will the wiimote price soar?

Will 'oem' version start to appear? :-)

Hi there

Glad to have found this forum!!

I am an electronics hobbyist always looking for interesting projects to do..

Hi there

I want something that is self-powered without any dangling cord. Small but controllable, able to press on/off, and I came up with this:

- Single core wires
- Screws and nuts
- 2 x cable lugs
- plastic washers
- 8-pin I socket
- Micro push button switch
- 2 x LR44 button batteries

I do not have an appropriate resistor so I am driving the IR LED directly from the batteries.
The reason for the 8-pin IC socket is to allow me to add a resistor later on and to change LED whenever it blows :-(
