I was thinking about making a passive light sensor with 2 Csd components
mounted at slightly off parallel ( diverging ) and use the Light Sensor Type
to read the left, then switch it to Touch Type to read the right element. I
should be able to use the change in voltage to determine which element to
read. If anyone has thought of this and made a circuit I'd greatly
appreciate it - otherwise its back to the my old textbooks. It should be
pretty simple, my old roommate dropped out of EE - he should be able to help
me.

| I wonder if the same approach that has been found for touch sensors may apply here to. That is can the Csd Sensors be connected is parrallel to a couple or three series resisters. Then when light hits the left sensor it generates a number and when (...) (26 years ago, 31-Dec-98, to lugnet.robotics)

| This design would prevent multiple switch detection. Only one switch would be detectable (the last one). The designs people have been creating so far have been capable of detecting 3-4 discrete inputs at any time regardless of the settings of any (...) (26 years ago, 30-Dec-98, to lugnet.robotics)
