So if i put a battery of IR Leds in the top of monitor, near webcam looking cap and the 4 points reflectors... will it work? Or is necessary to put LEDS on a cap? The price of this "Vector Clip" is 9,95$ in naturalpoint.com Anyone has tried it?

When someone that own this kind of webcam or illuminator, will give a try, we will know for sure. Stay FREE

Class : Habitué Posts : 54 Registered on : 03/09/2007 Off line	OK As Suggested by Kestrel.... ....try to build an IR light source to shine on reflectors and a circular piece of reflective material. So we need also ...a battery pack (2x1,5v) What kind of leds to buy and where? How many leds an illuminator needs? maybe 4 as in the trackir? or we need 6-8 leds? At the end of the work the goal is to obtain a screen like this in Freetrack. Stay FREE

I have a webcam with 2 infrared led pointed in front of me and I used a reflecting stripe removed from an emergency jacket. System work better without ir filter but if you have so light in the room will be a problem.

Class : Apprenti Posts : 10 Registered on : 02/10/2007 Off line	No, I tried using a plastic glass ir filter removed from an old VCR. I was installed in front of remote ir sensor. Do you think a negative photo-film work better?

We need the pfoto film to ONLY allow IR light to the sensor.

Class : Apprenti Posts : 10 Registered on : 02/10/2007 Off line	The IR filter blocks IR light Mmmhhh It was installed in front of reciver ir sensor, if it blocks IR light, how can work the remote control? Also, looking the filter it appear very dark and just some red color can pass trough it. Here my custom vector:

Class : Habitué Posts : 54 Registered on : 03/09/2007 Off line	I've never tried to use the plastic from a vcr, but with the photo film you can add several layers of film until the webcam see only the reflective parts, and surely doesn't block ir rays in input and return. I'm making a test with an 8 IR leds illuminator..I'll let u know Stay FREE

Class : Habitué Posts : 54 Registered on : 03/09/2007 Off line	Experiment just finished! it works fine for me. I've used an ir illuminator with 8 leds, it's a camera for home video surveillance system like this A little reflective piece stolen from an emergency jacket And my webcam Philips Toucam Pro without ir filter This is the result Light condition of the room in the image is a normal strong desk lamp turned against the wall for a diffused light, with the room's chandelier on, the result does not chenge! Obviously if I turn the desklamp on my face my webcam loose the point and all my clear face parts are visible in the screen, but this is no more a test but a suicide...as far as I know, trackir could not be used correctly with too much light in the room. I'm satisfied, but now I must build an ir illuminator Edited by luca on 25/10/2007 at 00h43. Stay FREE
