I think I read someplace that if you remove the red led from the light
sensor it works much better.
Has any one done this and if so how did it work?


Removing the LED makes it work over a wider range (0 to 100), but probably
at a slight loss of low light sensitivity.  There is an analysis of the
subject in the LEGO Light sensor section on my web page:
http://www.plazaearth.com/usr/gasperi/lego.htm  Digging into the sensor is
not easy or reversable.  I would highly recomend you make a passive light
sensor using a CdS photocell you can get from RadioShack.  Information for
this is in the Homebrew section.
