| (...) I have built a GBC ball counting module, that work perfectly well. The trick is to use a LEGO lamp in front of a light sensor, with the balls passing between them (you must also be sure that balls arrive one at a time). Using NQC events based (...)

No slave-slave communication is possible via the current spec (heh heh research people are working on this as well). A small network of bluetooth devices is (...)

| (...) The speed of the motor attached to another robot in the video shows that its speed is significantly slower than the 71427 motors supplied with the RCX 1.0 to 2.0. I suggest more like 60-100rpm rather than 300. This gives more torque for the (...) (20 years ago, 7-Jan-06, to lugnet.robotics, FTX)
