The above is the title of an article from EDN magazine (Feb 18,2010) I thought it might be very relevant to the search for Mark's secret especially since a rotating field was shown by a spinning compass needle. 
 
I'd post the link but I can't get paste to work in this post.  Do a Google using that title and it should come up. The driver chip is particularly interesting (L6204).

Did you try Control-V ?  Thanks - that's the article above.  It mentions using a PIC controller and doesn't seem to really show a whole circuit.  Not sure how useful that's going to be unless you already are fairly good at circuit design but I might be missing something.  It looks like it basically is using 4 inducters in a circle or square and triggering them in sequence.  I doubt if he was using a PIC - don't think they even had them when he built the first TPU's.  Didn't the first Parallax PIC controllers come out in the late 80's or early 90's?

The B field of a straight wire, with enough current can also spin a compass.  That was the whole point of why he wrote that.  To show it was not a solonoid, but the B field of the transmission line/output collectors.

Hi bruce,


do you think i should use strait wires in a cylinder  or a toroid to achieve this .
i need a solid state rotating field on my circuit .
