I can guide you through it on thursday evening if you would like. Fairly easy exercise.
What you have to do with your camera is to open the assembly, remove the lens, remove the IR filter (different from each model), put it back together, focus the lens (just reattach it to the computer and rotate the lens until you get a clear picture)
Then you tape a piece of floppydisc over the camera lens, and presto you have yourself an IR tracker.
All you need to do then is construct the cap/clip. I'll help you with the setup of the software.
