FreeTrack Forum

I have a logitec STX webcam. I've removed the IR filter and plan on using a floppy disc as my visible light filter. Can I just cut it to shape and mound it in the "frame" from which I removed the IR filter? Do I need to do anything special to it or do I just cut it out of an unformatted disc? I was also wondering if I can use the IR emitters from a TV remote? If not, it's no big deal. I would also like to use USB power to run the IR emitters. Is anyone doing this and can you tell me which LED's to buy? I plan on doing a 3 LED setup attached to my mic.
Thanks for your help.

It would seem as though Tristan answered the USB LED question a few threads down. Sorry about the repeat question.

The camera's fully modded for IR (Logitech STX communicate). I've downloaded and installed the FreeTrack software then setup the camera for 28FPS. I even verified functionality with a TV remote(very cool). I have to go pick up a resistor tonight. I purchased some IR LEDs and sanded them flat. Which brings me to a couple of questions. First my LED choice. I got them at the local Radio Shack. The specs are: Absolute maximum rating (25 deg C)
Foward voltage (20ma) 1.6v
Reverse voltage 5v
Reverse current 10uA
Wavelength 940nm

Electrical characteristics:
Radiant power output (100ma) 16mW min.
Foward voltage 1.2v
Foward current 100mA
Viewing angle to 1/2 intensity 45deg.

Do you see anything in the specs that would make this LED a bad choice?

I've sanded the LEDs ending with a 2000 grit sandpaper. should I polish them up? I thought I read to leave them with a matt finish.

Thanks,
John
