So, you discovered the principle of wired-together motors more or less by accident?--then, while (...) (25 years ago, 30-Oct-99, to lugnet.build, lugnet.edu, lugnet.general, lugnet.technic)

|

In the inaugural issue of Ohio Today (Fall 1999), page 18 has an article about how a teacher at OU uses lego to teach math to blind students. They were into Algebra, and even had representations for polynomials. I'm not sure what I'll need to do to (...) (25 years ago, 30-Oct-99, to lugnet.general, lugnet.edu)

I've found that the motors typically have large variations in speed that make the robot veer to (...) (25 years ago, 29-Oct-99, to lugnet.edu, lugnet.technic, lugnet.robotics)

Todd, the stuff with the motors is Very interesting. A friend has two small motors/generators with cranks that he bought at some expensive educational materials store for about $25 I think. They run small pilot lamps well, and can do the (...) (25 years ago, 29-Oct-99, to lugnet.edu, lugnet.technic)
