Sorry for that, but it is officialy dead now. Last year I had no motivation to continue with it - the development consumed some money and a lot of time - in the meantime I sold spectrum analyser, high voltage sources to make the money back, at least partially.

I think the concept is still valid and feasible, but the amount of experimenting needed is unbearable for hobby project. All my output from this project is conserved here, for future reference, so anyone can catch up and continue.
