(...) Do you have the Lego part numbers for these? Is the capacitor like the commercial MaxCaps or SuperCaps? If so, we use these for NVRAM backup and could use them or might make them available to interested people. Thanks Bruce Boyes ------- (...) (24 years ago, 26-Mar-01, to lugnet.robotics)

Gordon, That is a good question. And I agree, there isn't much out there in this regard. In my book I talk about very simple (1D) robot navigation - remembering a place that you went to and going back to it. As far as more complex navigation goes (...) (24 years ago, 27-Mar-01, to lugnet.robotics)

This whole Lego capacitor thing strikes me as somewhat intriguing. The super-caps, which are doubtless used, absolutely cannot be charged backwards, they have to have the correct polarity. And all the Lego electrical "stuff" like the RCX sensors, (...) (24 years ago, 27-Mar-01, to lugnet.robotics)

(...) The capacitor is very much polarity-sensitive. It has +/- polarity indicators on either side of the standard 2x2 9V terminal, as does the solar cell, and it will not work if the polarity is reversed. (24 years ago, 27-Mar-01, to lugnet.robotics)
