I got Extreme Creatures about a month ago when it was last on special at S@H for $25. I guess for the Fibre Optic unit and the collection of parts, it's not a bad price. As far as I can tell, it's the only way you can get the FOS main unit from (...) (25 years ago, 5-Oct-00, to lugnet.market.shopping, lugnet.robotics.rcx, lugnet.robotics, lugnet.technic)

(...) You can use any brush-type DC motor as a generator. (...) Well, *almost* exactly: there's got to be at least some loss in the system. But the fact that you can't spot the error speaks well of Technic motors. (...) It takes very strong magnets, (...) (25 years ago, 5-Oct-00, to lugnet.technic)

These motors, used in Mindstorms, have 3 programmed states: On, Off and Float. When 'On' the motor runs at the set power level. When 'Floated' the motor coasts to a stop (power removed). When 'Off' the motor brakes to a stop. This braking is quite (...) (25 years ago, 5-Oct-00, to lugnet.technic)

That alternative implementation gives me an idea. What about putting gear wheels around on arms sticking out at various angles and held together by structural Technic parts, and having various combinations meshing with each other? The only problem (...) (25 years ago, 4-Oct-00, to lugnet.technic)

Ah. Hm, I wonder if it could be used for a lego transmission. I cleaned up my first planetary gear, and I came up with a second implementation. It is bigger, and it is not obviously a planetary system, but I think it is topologically equivalent. It (...) (25 years ago, 4-Oct-00, to lugnet.technic)
