Hi Philo and color light sensor interested people:
I know that Mike Gasperi has designed an unexpensive super color-sensor
based on an input-multiplexer which is driven by switching the RCX from
passive to active sensor-mode all the time. The information is passed
through analog switches. Mike has published this recently in an article. You
should ask him. He also has a ready for soldering PCBoard for this sensor.
And it works well!
Otherwise, I recommend Robolab 2.5 with the Lego Camera or like JP Brown in
his Rubik's Cube solver, the Logitech-camera-package. We are experimenting
with the Camera-feature of Robolab 2.5 and we are really amazed what you can
do with it. Some pages will follow during the next months at our site.
