hi fellows
i´ve built my 3 point clip yesterday. used the recommended leds, a 6 volt power supply and a 47 ohm resistor. as a webcam i got the microsoft vx 3000. when i get it to run, i´ll post some photos. operating system is win xp and there are no other applications running, that are using the webcam. now i´m trying to make it work. the webcam is prepared by removing the ir-filter and i also put a part of the floppydisk in front of the lense. when i start freetrack in "cam-mode" i can see the 3 lights quite bright on the videoscreen, but when i moove the clip, the "head" is not reacting at all.  beneeth the source-button it says 30 fps and 0 jps. the red lights beneeth the center-button do not shine. (i tested it before the webcam modifications, and i could make the head moove a little when i set the threshhold really low) testing with my tv remote control does also not work. i also see the light, but the head also does not moove. i really would appreciate your help. greets |

 Wild guess: Did you change to '1 single point' on 'Model' tab? |

While you are testing with rc, go to 'Model' tab and choose '1 single point'. In bottom right corner it should be icon with head and number 1. Bellow, it should be 1 green and 4 grey 'lights'. It is indication that you have one dot 'in track'.
This is important because with '3 point clip' and 1 light source, head is not supposed to move. Also, try to get closer with rc. Maybe, dot is still small... If it doesn't work, take print screen and post it... Hope it will work at the end |

I've just tried with rc. It have really big dot. I needed to move back, to make dot smaller, to get tracking work. Also my rc light flickers. Just a few jinks moves.
So, I took cigarette lighter (although I quit  ) with blue LED and make SS for you.What are differences (except in cam model) compared to your screen? Do you have cross on light?  |

I'm glad that works
Also, its recommended to change dot color to white. - Go to 'Cam' tab - Before starting tracking click on 'Stream' - Change 'Color space / compression' to 'I420' (or anything else but RGB24/RGB32) |
