| | | I'll care what the voltage is, becuase I have to buy batteries for it/use a wall wart. Higher voltage == more batteries/more expensive batteries, and also more space. So, it seems to me (since the RCX/siblings are already fairly large on a Lego (...) (22 years ago, 2-Sep-02, to lugnet.robotics)

To at least a first approximation, you'll use the same number of batteries no matter which voltage (...) (22 years ago, 2-Sep-02, to lugnet.robotics)

You need more batteries to get the higher voltage (or a step-up transformer to raise the voltage, but (...) (22 years ago, 2-Sep-02, to lugnet.robotics)

Yes - but in this hypothetical nightmarish world, there would (...) (22 years ago, 2-Sep-02, to lugnet.robotics)

I think you'd have to be pretty desperate to want to do that...especially (...) (22 years ago, 2-Sep-02, to lugnet.robotics)

These outputs could easily be hacked to control additional motors using an external 9V battery box and some simple (...) (22 years ago, 3-Sep-02, to lugnet.robotics)
