 Speaking for all the idiots out here who know just enough to figure out
which end of the soldering iron to hold, I just have to say that I stand in
complete awe of people like this who can take a relatively abstract
theoretical concept and turn it into a circuit that oscillates (or does
anything besides smoke and blow the fuses). I don't understand quite all of
this, but this is exciting and inspiring stuff! Kudos to Ian, Michael, Peter
and several others who have recently posted about new circuit topologies!
