Hello guys, I´m new and my name is daniel, I come from germany!
I´d build my headtracking system, but my IR-LED aren´t really working there is only a little red point in the middle of the LED, is that right?!

My schematic:

[+5V USB Power] -> Fuse (60 V; 0.2 A) -> Resistor 10 Ohms -> IR 1 -> IR 2 -> IR 3 ->[- USB]

What could be wrong if it is so, my LED´s are the recommed OSRAM and got right polarity??!
Please help me!

No, they are working. They are IR - "Infra-Red"  LED"s.  They don't pass light through the visual spectrum. So your IR lights are working properly!

Now, the important thing is to make sure that you remove the IR filter now from your camera.  Remove the lens and take out, very carefully, the little piece of orange-red glass out from behind the lens.


Hopefully that helps

Thanky a lot, my system works great! But one question: In which position should i mount my webcam, i´ve got a headset-3 LED-system (vertical)?

I run my camera on top of my monitor. Now your monitor setup will dictate the best placement of your camera.

Remember, you want the camera to be as close to eye level as possible and as centered as possible.

This presents a few challenges for users who have multiple monitors and/ or mounted monitors at eye level.

So, if you run a monitor on your desktop, then I would place the camera above the monitor.

If the monitor is eye level either mount it on the side (if you don't have multiple monitors).  Otherwise mount it on the top.

Now, if the camera is higher or lower than you head, you're going to get some degradation in movement forward and back. Meaning, that you're going to either taper up or down on screen as you move your head forward or back in reference to the camera's position.

Good luck!
