Hubbard coil

[z.monkey]

Howdy Y'all,

Hey Grumpy, I had another thought about the more advanced version of the Hubbard Coil you are working with.  The technology used to built the voltage distribution system is archaic.  We should modernize this thing if we are going to the trouble of unlocking the secrets of the technology and documenting it.  Where Hubbard had a motor, V8 distributor and an ignition coil we will do this with state of the art technology.  Just for kicks lets say a Microchip processor driving some MOSFET preamplifers which drive some heavy duty MOSFETs hooked up to individual miniature flyback transformers.  Each flyback transformer is connected to one of the outer coils on the Hubbard Coil.  This way we can programmatically alter rotation, frequency, duration and amplitude of the pulses going to the Hubbard Coil.  All this technology to drive a Hubbard Coil?  Why?  As we explore and learn the secrets of this device it might be useful to have the additional flexibility in the control circuits.  We don't have to use a Microchip processor, that is the brand I am familiar with using.  I have some single channel driver boards like this built already.  So I can just modify my design to make them eight channel instead of one.  I think we may need the flexibility if the Hubbard Coil is capable of doing what I think it is capable of.

After a quick thought about EMdevices' original "infinite bifilar coil" design, I've noticed one thing.

If you consider one direction, voltage of a initial injected impulse will be rising infinitely while amperage dimishing infinitely. In opposite direction, voltage will be diminishing infinitely, but amperage increasing infinitely. How do high-voltage and high-amperage active loads interact when they are connected via bifilar coil?

tonight when I get home I will post a very interesting setup I discovered yesterday evening, by mistake!!

I was setting up a very simple blocking oscillator on my small breadboard, which I had done many times before and I was getting this strange high frequency "hash"  couldn't figure out what was happening.  I changed transistors and the same thing.   I was puzzled for quite a while but decided to explore the phenomena  (ususally means bringing magnets close to the core,  LOL  )   and I noticed it was not changing the frequency that much, but some.   Also, the frequency was so high, never seen it so high before, it was up to 50 MHz or so (not a clean sinusoid, but close).   Then I decided to load the output down with a 100 ohm resistor and the peak to peak voltages were still 10 Volts or so, so I figure a power output of about 10*10/100 = 1 watt,  and the resistor got realy got, but the input amps to this thing was realy low, 50 mili Amps or so from 10 volts,  I'm like all stoked, not sure what this means, but I need to explore it some more to make sure it's not measurement error cause I've been bit by that before.   Like I said, I discovered it by accident, and later determined why my oscillator wasn't working properly,  I had reversed two wires, just as simple as that.    By the way, without the 100 ohm resistor, the output swings 40 Volts plus and minus, never been able to get that before.  Also, I hooked up a variable capacitor and started adjusting, and the core starting singing, but the frequency shown on the scope is too high for sound production, so another weird phenomena.    I'm not sure what resonates, it could be magnetostriciton, but then again, it's way too high of a frequency, maybe it's a higher harmonic or something.  Maybe it's the capacitance around the coils, who knows.   I have a feeling it might be a case like Dr Stiffler's coils, where he found out that he can reduce his circuit complexity down to just a strip of copper, since he was dealing with high frequencies as well.   I'll have to do much more exploring on this to be sure I understand it.

Howdy Y'all,

Aleks, I had considered those possibilities, and was considering wiring the coil in that way anyway.  But after another thought tangent occurred to me I have changed plans once again.

GiantKiller, I once left the ground off the noninverting input of a split voltage power amplifier circuit and it went into oscillation at over a megahertz.  I picked up the local AM station clear as a bell.

Howdy Y'all,

LocalJoe, guitar player, huh, me too...  I have noticed that knowledge of music helps me to understand electronics and resonant systems much better.  You have a thorough understanding of resonance after playing a Dreadnaught.  See, people who don't understand music don't know what a Dreadnaught is, so they just don't understand resonance...
