  Re: NELUG participates in December 2nd and 3rd Greenberg Show.
 
(...) used. I was nice to see some validation of using 4 baseplate wide tables. My table will be the same except my individual modules will be 2x4 baseplates square instead of 4x8. I'm hoping to transport the modules with the Lego on them, and I (...) (24 years ago, 5-Dec-00, to lugnet.general, lugnet.org.us.nelug, lugnet.trains, lugnet.loc.us.ma)

This way they use the omni light from the room as the (...) (24 years ago, 5-Dec-00, to lugnet.trains, lugnet.robotics)
 
  reed switch w/2^n series resister
 
Chris If I understand correctly you can add a series resister to each reed switch using the formula r=2^n*R. Where n is the number of each switch (1,2,3...) and R is some resistence value that is friendly to the RCX. This way you can add several (...)
