[sdiy] mine transformer question....

[Rude 66]

did anything ever happen to the grand plans from a while ago to put all this
diy info in a book, on a webpage, etc? there was much discussion about
writng repair manuals, articles, etc. did anything ever come from that? or
was it good intentions as usual, but not enough time? ;-)
