Richard Hull describes the Tesla magnifier work of the Tesla Coil Builders of Richmond (T.C.B.O.R.) group and introduces his "The Tesla Coil Builder's Guide to the Colorado Springs Notes of Nikola Tesla" book.
I saw this material in the form of a printed article, its nice to see the author presenting it (even if I disagree about the lack of usefulness of the underlying mathematics). I have found that a proper mathematical design, coupled with the materials design approach described by RH, requires very little adjustment to get great results with 2-coil and 3-coil systems. By the way, the audio is very quiet and there is a long spell of nothing at the end of the video!
Yep, this one was not from a great source to start with and no matter how I seemed to try and fix it, the audio would get out of sync. I could get it right at the end or the beginning, but not both. So I finally gave up and just uploaded the file directly, as-is.
I don't think Richard's intention was to belittle the role of mathematics to design a well operating system. I think his point was that mathematics can blind you to other possible modes of operation. Experimentation is ideal for discovery, then mathematics comes in so the system can be perfected.
Do you guys keep your smartphones and laptop computers in a metal box? Acting as a Faraday cage when experimenting around large Tesla Coils? What I'm wondering is will the smartphone's GSM, 4G and WiFi radio waves attract the lightnings from the Tesla Coils? Thus risk frying my computer equipment.
