(...) Measuring PWM is not difficult, but it would involve a micro (PIC12C508 anyone?) dedicated to the task and then you would have to get it to drive the RCX, which means motor drivers, etc. If you are willing to spend $50 and LOTS of time, then (...)

My original message described the controller with two inputs, one for device selection and one for device power. This could easily be connected to whatever power source the user desires. (...) (26 years ago, 26-Mar-99, to lugnet.robotics)

I think that the solution should also be flexible enough to allow the power to be plugged into either an RCX output port or a battery pack. That way if you didn't want to lug around another battery pack, or if you didn't want to use up another (...) (26 years ago, 26-Mar-99, to lugnet.robotics)

Yeah it probably is! Welcome to our little part of the world :) Where exactly is Prescott?? I'm pretty sure I've been in it..
