(...) That sounds like a great plan though we did actually pick a mini-challenge at the last meeting. I should have posted something about it but I guess I never got around to it. My bad.

As no mini-challenge was posted, we'll try a very low-key variation on BrickHeap Wars for this meeting. It will be an individual (or (...) (14 years ago, 14-Jan-11, to lugnet.org.us.smart)

Hi Brian, (...) I was surprised too. I suspect a relatively high internal resistance of the windings, rather than mechanical friction, as the source of losses. No, (shame on me!)
