IDK but I think this old book has something related to your projects. "Design, Construction & Operating Principles of Electromagnets for Attracting Copper Aluminum & Other Non-Ferrous Metals" By Leonard R. Crow (1951)
Gee, my Physics Lab partner and I built a TUBE-based Tesla Coil in 1969, my Junior year in high skrul from "plans" in a Popular Mechanics magazine. When the humidity was low, (rare in Okra-Homer) we threw 12 meter "lighting bolts" across the classroom. The "rotary fire cones" were the most spectacular thing. Balance a flattened "Z" shaped needle on the top, and it will rotate at the resonant frequency with a cone of multi-colored "electric discharge" from each end. BEAUTIFUL! We also ground a 4" mirror for a Newtonian reflector telescope (Edmund's Scientific) that ALMOST would resolve Polaris. I got pneumonia and flunked-out of 2nd Semester. Smallest class this REAL "baby-boomer" ever had in Pubic Skrul-only 38 students! "Ancient and Medieval History" with the late Margery Pike (Tony Randall's and my MOTHER'S history teacher!) we had 56 in her class. If you had to "make a trip" a half-dozen others had to move their desks. Tony R. and Momma had (wartime) 70+ in the same room!!!
Shawn and I had to learn it from scratch. We also had to find where the #1 coil could pick up the resonance frequency. It makes such a difference knowing all of that. We are making a big video on it. We are trying to map it all out so people can just buy the parts and make it work without any issue. The goal is to make it more user friendly for people who know nothing right now but want to build one.
so I believe it is a npn. Normally you can use a pnp. They are different connections. I should have made that clear in the video. My coil was 300khz out of resonance in the video. I could have gotten a higher voltage to be steady if I knew it at the time. I should have also used a snubber to stop the heat in the circuit from affecting the power level.
pancake coil, for primary. this is to satisfy 90 degrees out of phase. placing the primary at the 1/4 wave position. format the air/dialectic with the use of the piezo. transmission with sympathetic vibration . format the air at the receiver....
I am going to use the 1/4" copper and just wind it. I don't know if the zvs can do the 90 degrees. If I wanted to run a spark gap the 90 would be perfect for the size of these coils.
You have a signal generator. Can you not find the recount freq of any coil With a simple bridge that balances resistance against the inductance of the coil? and if you have Nothing a variable resistor in series of the coil and adjust until you see the same voltage across the coil and the resistor? You can do this at low power. You had LONG wires in one of the setups that didn't work and those added inductance in series. ?? Old man here . The bridge circuits I remember from Rockwell international. Was lucky enough to work in the Microwave Repair and Calibration department.
The long wires get cut down when the top load goes on and the bottom wire gets soldered. Before I went there I wanted to test the numbers. each one will go down a little as I add the top load. The java shows it with a top load. My goal today to to do all the clean up.
It would increase the dielectric storage coefficient instead of the magnetic, and it would respond with a dielectric field instead of a magnetic field when induced, albeit weak compared to something like quartz.
@@billschwandt1 It's the original and more accurate name for the "electric" field, also called the electrostatic field, aether tension, Faraday and Steinmetz referred to it as such.
