It occurs to me that a pure Lego solution could be constructed fron a
fibre-optic doodad and a light sensor. Get your mechanisim to rotate the
fibre-optic rotator, use one fibre pointing at the light sensor, and bingo!
instant anero...wossname. and no nasty resistors or solder near your nice lego
:)

| There is a better way to use the fiber optic doodad as a rotation sensor: just connect it to the RCX on an input configured as a light-sensor and count pulses in electrical resistance. Read more here: (URL) -----Original Message----- (...) (URL) (...) (25 years ago, 21-Jan-99, to lugnet.robotics)
