Hi allI've substituted my red leds with a standard infrared leds model, and I've sanded as described by Kestrel in some posts.
Confronted to the red leds, now the light is much more shiny, so the 3 dot in FT are a little bit spiky, lowering the threshold to remove spikes makes the white dots too much small and the tracking is not clean.

Obviously I've covered the webcam lens with 1 or more layers of floppy, but no way to obtain a clean image, there are some tips?

no other tips than one layer of floppy disk on webcam (not more  :wacko: ) ...
Stop all auto features of your webcam driver (like auto exposure ...) ...

Your webcam's exposure should be used as the primary means of brightness control, the threshold slider is secondary.
