In the 'Right way' diagram the gate is left to float or
be susceptible to noise. I also mentioned the high side fet made a difference before. Marco and Armagdn3 pointed this out to me. The coil gets hit first when the fet conducts. Later, a post was made that this makes no difference. I still contend, like Otto, this does. This is how I do all my tests now. Coil connected as low side to ground of the circuit.
With the oscillator and the PS isolated the gate is the only bridge between the 2 stages. This makes it look like an antenna. Noise can effect the fet operation.
I will run off a 12v battery and check this too.
In talking with Jason we both agree that the light seen is glowing is current. The color scheme would be red, orange, yellow. If white is never seen then the operation is current and rf. If a white glow is achieved then RE is achieved. The high speed RE reacts with the inductance not the conductance of the filament. So this test is showing a crossover point in understanding and using different bandwidths of energies.
This whole output stage is in series which allows current flow. Granted the current setup is mobius wound. This is a constant! Now imagine this. You dump a cap into a coil. This is very high voltage, high speed. The inductor screams bloody murder! No conduction and the field snaps against the wire going through the middle. The same wire that feeds or bleeds the same conduction pathway. Regardless of polarities, this excitation excludes time as a normal timeframe or measurement we normally understand or work with. The dynamics are of immense importantance because these effects are beyond what we have first taken to the bench in this pursuit.
Jason and I talked about this last night. We are going to pursue this build. Our concerns are focused on the gates of the fet. I want to back up one step and not use a fet but drive that mobius winding with a stun gun using the high voltage shock into the inductor. I did this with the GK4 before. Lo and behold, there were purple dartlets between the outside winding through the space to my finger tip at a distance of 1/2 inch.
Another point I wish to make is the single coil architecture. There are 3 topologies.
1: Machine wound back and forth. Very smooth and layers going in 2 different directions.
2: Hand wound back and forth. Alot of overlaps or messy weaving, like a bad Rodin coil. Random nodes all over the place.
3: Hand wound only in 1 direction with a half of circumference return wind then forward again. Overlaps still exist.
I have a winder that can do option 3. The return wind makes a bump under then next layer though.
Does all this make a difference? Lets say you had a machine wound option #3. The finished coil would look like a pancake coil but with height. Concentric winds like a canister with in a canister and driven in all the same direction. The power of the Pancake magnified. The clue is Tesla sitting in front of his 8 foot pancake coil. He is showing a clue to those who want to know. If coil mechanics didn't matter then we have no basis for what transformers look like.
Gotoluc did a cap charging test with a square coil
I see 2 high voltage spike type circuits.
1 is the BEMF is recycled
2 is the high speed charge is actually after a spark gap into a coil. The coil responds differently.
1 is a loop circuit and 2 is a linear circuit. #2 is where N.Telsa focuses on the majority of his tests. Now there is a loop in all of Tesla's circuits. In the feedback loop is a slower dielectric. Not in the circuit but on the circuit. He boosts the charge far above the medium so the flow doesn't look like losses but emmits discharges.
What does all this have to do with Otto's mobius winds. In a short answer is snapping the fields. Hit a coil with a very fast charge. The forced magnetic moment of the electrons obeying then the coil releasing that immense paradigm change into a cap. We don't get more than what we put in. It looks that way. We boost the energy to charge a medium then discharge that higher bandwidth into a lower medium, the light bulb or cap. But it is what happens after the spark gap discharge. Pump that into a coil to store then let it discharge to capture or see it.
