I'll show the setup to my dad (electrical engineer), and see if it's watertight. I know he'll be skeptical about the resonance part, but I know he'll be willing to give it a try.
It seemed familar somehow... I read the same part (on the coil system) on a near-dead web page a few years ago, and it has disappeared since. I'm surprised someone actually still had it written down. Thanks a million. I've already copied/pasted it and saved it to my documents.
Of course, I understand much more of the article now than I did then, and it still sounds just as amazing. There's a ~75 foot tall spruce tree in the front yard, and a ~100'+ poplar in the neighbour's backyard, (but the wood is much too soft to mount anything to). I think I have quite a nice winter project lined up...
