Does anybody have a PCB design for the ZLT-CCR2 regulator circuit that is the subject of this thread: http://www.candlepowerforums.com/ubb...art=1&vc=1 ?

I want to make an inductor for this circuit, but my knowledge about electromagnetics is very limited. I was looking at some toroid cores at http://www.elfa.se/elfa-bin/dyndok.p...ok=2011480.htm - can anybody see which toroid, if any, of the ones described there can be used to make a suitable inductor for the ZLT++?
