(...) $100 for a 1906 is one heck of an oddity. I paid something like $38 including shipping for a brand new sealed copy about 6 months ago, and I don't recall seeing one go over $50 at any other time. Just goes to show you that auctions sometimes (...) (25 years ago, 9-Aug-99, to lugnet.market.theory)

(...) I think someone posted to the list that the micromotor has an internal shutoff when it stalls, so that it can't burn out the coils. This seems consistent with what I see when playing with the motor. If I turn it on an then stall it with my (...) (25 years ago, 9-Aug-99, to lugnet.robotics)

Hi, I don't live in California so I don't usually post in the SF local group (although I lived on Treasure Island and went to Berkeley for a summer)... but I noticed your message about trading for these minifigs. I'm trying to get my hands on a (...) (25 years ago, 9-Aug-99, to lugnet.loc.us.ca.sf)

Hi David, Are you sure Ben's grabber won't work for you? Using a smaller and lighter grabber based on his original design, I can pick up one of those wheels. What exactly doesn't work? Here's my design (Minerva): (...) -- Did you check the web site (...) (25 years ago, 9-Aug-99, to lugnet.robotics)

Thanks for the info John, very informative. If we got group orders in bulks of 50,000 or 100,000, would that be enough to justify a special run of specialty pieces (such as 1x2x2 windows, 2x2 cylinder bricks, 2x2 tiles)? Gary Istok (...) (25 years ago, 9-Aug-99, to lugnet.general)

|

(...) The brake concept can be easily demonstrated. 1. Hook up two motors to two separate RCX outputs. Put a big motorcycle wheel on each so you can see them spinning easily. 2. Hook up a touch sensor to one of the RCX inputs. 3. Program the RCX so (...) (25 years ago, 9-Aug-99, to lugnet.robotics)

(...) A motor is just some coils attached to the shaft, which move through the field of a permanent magnet. When current flows through the coils, they become magnets and react with the permanent field. But I'm sure you already knew that. There are (...) (25 years ago, 9-Aug-99, to lugnet.robotics)

Hello, Ok, I haven't actually done this but I have given it some thought. First, imagine that you just want to lift the arm. A classic way would be to put a gear into the pivot point that was fixed to the arm. Another gear in the platform could turn (...) (25 years ago, 9-Aug-99, to lugnet.robotics)
