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 (...) (25 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 (...) (25 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 (...) (25 years ago, 5-Sep-99, to lugnet.robotics.rcx)

(...) I second that! I tried using the "native" language and its limitations baffled me. I never got a program downloaded. I jumped straight to NQC and have done several now. Good work Dave! DLC (25 years ago, 5-Sep-99, to lugnet.robotics.rcx.nqc)

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 (25 years ago, 4-Sep-99, to lugnet.robotics.rcx)

Woaw ! This could be great to have a full featured rcx expansion board... It should however be not too expensive, and in my opinion very basic to allow anything to be made. A "simple" (hehe :-) 8 bit Input / Output expander would be very, very nice. (...) (25 years ago, 4-Sep-99, to lugnet.robotics.rcx.nqc)
