Yes it is slow, if you count 1/2 a second slow, but not horrible. The big problem comes with control. Finding neutral again. NQC to the rescue. I find its better for this application than the RIS software. More open for creating servo control loops. (...) (27 years ago, 6-Sep-99, to lugnet.robotics.rcx)

You mean you use the red motor/switch combination as a sort of 'electronic' fuse? Oh, right. While I'm typing I suddenly see what you mean. You use an external power supply for the motors. Clever. Isn't the switching a little slow using the (...) (27 years ago, 5-Sep-99, to lugnet.robotics.rcx)

The best way to avoid high current running thru the brick is to control a small red motor which drives one of the polarity switches which is hooked up to a battery pack and that in turn runs the main motors. We had this problem at the LEGO (...) (27 years ago, 5-Sep-99, to lugnet.robotics.rcx)

MJ, The RCX itself does not need a lot of power. However, if you're going to run 2 motors off each output port (a total of 6), 200 mA won't be enough. I expect the motors to draw at least 100 mA each. Even more when stalled. Maximum power to be (...) (27 years ago, 5-Sep-99, to lugnet.robotics.rcx)

Hi, I have a 9V adapter that will fit the RCX. It has a current rating of 200mA. What is the current rating for ther RCX? I have seen adapters that are rated from 100mA up to 800mA. Thx...MJ (27 years ago, 4-Sep-99, to lugnet.robotics.rcx)

my rcx works fine with a universal ac to dc wall outlet. it has a switch to change the voltage. i've got it set at 9v and it operates at 800mA max. i figured 6 batteries x 1.5v =9v. i think it was originally for a keyboard (musical instrument, not (...)
