(...) If the motor runs on 9V anyway, just hook it up to RCX directly (assuming it only draws 500ma). If it needs more than that, hook an external battery up to it via a power transistor (either bipolar or FET). You'll need a resistor in series with (...)

Hi, If you have the SDK2 for the RIS then you have all you need to develop for the Scout. It uses the RCX 2.0 firmware, and all that is different is the following: 1 x built in light sensor (takes away one input). 1 x runnable program mode (select (...) (23 years ago, 18-Feb-02, to lugnet.robotics)

If they are a little bent they can loose that contact, which happened to my (...) (23 years ago, 17-Feb-02, to lugnet.robotics)

You didn't indicate whether it is an old-style 1.0 RCX (external adapter) or not, so I'll asume it's a batteries-only unit. First of all, do you have any experience with electronics? The first thing I'd be looking at after a mechanical shock would (...) (23 years ago, 17-Feb-02, to lugnet.robotics)
