I accidentaly discovered that when the sensor port on the RCX is set to light sensor type, a motor connected to it will run. The motor can only run in one direction with a low torque, but it can be useful when you just need the extra motion and (...) (25 years ago, 18-Jul-01, to lugnet.robotics.rcx)

Whoo hoo-- Toys R Us here in London, Ontario seems to have slashed the price on the RIS 1.5 down to $199CDN (about $120USD). That's a 1/3rd reduction in price and almost as good as the $150 that Future Shop online had last year. Now, how do I (...)
