Tesla Coil Dielectric Influence Experiment (5/3/22)
Did a quick mockup test with a Tesla Extra coil to see how increased surface and bulk capacitance affects the result. Surprisingly, despite the coil being a huge dielectric resonator, covering the entire thing in LDPE tape had no measurable impact on the resonant frequency, nor the Q (resonance) factor. Still incredibly sensitive to just…

Shop Notes 4/6 – Finishing+Assembling a 3kw Linear Amplifier
Finally getting in the last remaining parts to assemble this beautiful HAM radio linear amplifier that will soon be used in various Tesla-type experiments, so it’s finally time to put the major parts together and start testing to see if it lets the magic smoke out or not.🤫 I’m thinking of mounting inside a 3u…

Shop Notes 4/3 – Tesla Coil prelim experiment success
As a rough test it’s definitely not flashy, but it’s my first successful attempt to drive a Tesla coil with an external oscillator (HAM radio), and the first successful test with a grid bias board I had designed last month. See, most vacuum tube Tesla coils are usually armstrong oscillators that resonate against their own…

Parametrics and dreams
So, if all non-conservative electrical systems operate based on parametric variation (of permittivity/permeability), then applying a static DC potential and/or current to a simple Tesla Extra coil should result in small EMP-like impulses when the coil is energized with conventional standard RF near the resonant frequency. It’s crazy the things we think up when we’re…

3/28/22 – Linear amplifier initial tests
Doing some initial low-power tests with a cheap ‘100 watt’ linear HF amplifier for Tesla Coil experiments. Oddly, this amp seems to work best without a tuner. Perhaps some quirk with impedance, I haven’t tracked it down yet. Powering a Tesla Coil Extra it lights florescent bulbs nicely at a few feet away, though the…
