Unfortunately, I don't think there are any hamfests in my area.... actually,
that's probably not true, I just haven't been looking... In any case, I did
some calulations and realized I could get the exact capacitance I need in
a low loss, high-Q, durable polyethelyne cap with 3 boxes of Ziploc bags, some
aluminum foil, a tupperware container and miscellaneous other components.
I'll let everyone know how it turns out!
I did my first run with the salt water bottle caps, and what-do-you know, I
plug it in, hear a bzzzzzt-crack-hummmmmmmm sound. The bottle caps blew,
leaving an oily mess on my baseboard. I'm sure the poly cap will do better.
