Someone sent me an e-mail reply saying that they had used an external Lithium Ion battery pack to power their RCX, and that after a few days of use the RCX appeared to stop working, then they discovered that it only worked with internal batteries. (...) (25 years ago, 3-Aug-99, to lugnet.robotics)

Please note that in this particular case, the RCX is reported to still work with the internal batteries. That means the fault is somewhere in the path from the external connector to the main power "bus" within the RCX. Some component that is only (...) (25 years ago, 3-Aug-99, to lugnet.robotics)

(...) I think you will find that the bridge rectifier is in the internal battery circuit also, as the type of power socket used normally has only a single pole normally closed switch to disconnect the battery. I would suspect either the power (...) (25 years ago, 4-Aug-99, to lugnet.robotics)
