Hi everybody! I recently uploaded on my site PanoBot2, a RCX-controlled panoramic photography head, which can be build with RIS 1.5. See it, along with full building instructions, LeoCad files and sample panorama photographs at (URL) (25 years ago, 16-Oct-00, to lugnet.announce, lugnet.robotics)

Ncm is the metric measure for torque, imperial is ft/lb's hence 5Ncm is the the amount of torque required before the gear will 'slip', 2.5Ncm before it will engage again. the difference is the hysterisis. one would assume that Lego has a range of (...) (25 years ago, 16-Oct-00, to lugnet.robotics)

(...) I think Ncm is Newtons per centimeter, but I can't remember how a Newton is defined. So, if you're spinning the drive shaft, and the counter force on the gear teeth is less than 2.5 Ncm, you're fine. If the counter force on the gear teeth is (...) (25 years ago, 16-Oct-00, to lugnet.robotics)

Using the more restrictive criteria that the resistors only come from Radio Shack retail stores, you can't build a bullet proof four switch mux. However, I came up with a similar conclusion about the range of resistor values to use because of the (...) (25 years ago, 15-Oct-00, to lugnet.robotics)
