| 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)
