Hello all,

a long time ago it was said to use at least 12V.

I have a oridinary 12V, self made, power supply.

When you will work with your coils, sometimes, at some frequencies you may need 3 - 4A from your power supply!!! Of course this is not good at all but I will only show you the current. When my current from the power supply is over 2,5A I quickly change my frequencies because the MOSFETs with my heatsinks are VERY, VERY HOT!!
Pulse width always 50 - 50%.
Frequencies used: 0Hz - 1MHz but with my cheap caps in my oscillators Im not able to reach 1MHz and my 8038 IC used as oscillator cant reach this frequency and 1MHz we DONT need!!!

Everything is in the kHz range.

The above is a primer on resonance, for those of you that have forgotten the unintuitive effects of resonance/self-resonance in a circuit.

Take a look at question 8.  250mv AC input. Calculated voltages of over 4volts. That's 8 times input without a sniff of back EMF.

The 'Q' of a resonant circuit (see page 16) is defined as:

   Voltage Across Inductor/Voltage of Source   when at resonance.

You can easily have inductors with a Q of 50 to 100. Even up to 1000 with additional capacitor. That means on 12 volt input you could get observed voltage across an inductor of 600 volts with a Q of 50 at resonance. Resonance is the 'sweet spot'.

As you change frequencies the effective impedance of the coil changes from near enough 0 (high amps) to extremely high impedance (low amps). After all this is exactly the principal on which simple band-pass filter work. The principle of a cross-over network in your speakers to split bass and treble.

This is clearly what I observe with my circuit.

What is power out? I have seen no total power out measurements yet.

Where are the scope shots?

Are there inertial effects?

Spinning compass? 

@Mannix, your account name has been changed to Mannix. Your password should be the same as it was before.

Also, regarding Ronotte's post. I don't think what he did was a reproduction of Otto's setup. I think he did something else. I could be wrong. Perhaps Ronotte could clarify?

Hi Bob,

You make some really great points about the behavior of the circuit, and I believe that you have perfectly characterized its behavior from the standard perspective. But we must also realize that there may also be Radiant Energy effects taking place in addition to the standard electrical resonance effects.

Taking a few steps back, let?s consider what RE actually is. We know that Tesla worked with the stuff extensively with his spark gap experiments, which is all very well documented in his research papers and notes. He first noticed the effect when a switch was first tuned on and off. Now, one may play this off as simply inrush current and BEMF spikes but if you read more into the subject, you find that this oddball electrical effect does a whole lot more than make kicks.

When Tesla started doing experiments to duplicate the effect of the mechanical switching, he found that turning on and off a spark gap abruptly with ever decreasing switching time increase the intensity of the RE effect. When this occurred, he could create all kinds of effects ranging from cooling effects, to anomalous charging of nearby metal objects. He also noted that he felt pain from the discharges, which appeared to be unshieldable, even with a grounded faraday cage or led plate surrounding the discharge zone. I won?t go into further detail about all this but the point is that there could be more going on here in this simple circuit than what is predicted in the standard electrical theory. However, if you look in the physics world, there is nothing miraculous about this at all.

My understanding is that RE is simply super high-energy photons from the vacuum, or put simply, pure potential. This stuff behaves exactly in the same way as normal light photons in how it interacts with the electron. When we pulse our coils and abruptly shut off the flow of current, the radiant energy potential is ejected from the wires at 90 degrees in all directions. We can pick up a component of this discharge as an abrupt increase in the radial E-field around the wires. The intensity of this ejection is proportional to the applied power, and the speed at which the current is started and stopped. Keep in mind that all of this is in addition to the regular resonance and BEMF effects that we would expect to see.

When this high energy potential comes into contact with the electrons on neighboring metal objects, these photons increase the kinetic energy of the electrons in the wire, just like light striking a mass imparts momentum to it. There is nothing mysterious at all about this. So the whole point is that we can decouple the potential in our pulse coils from the source (transfer potential from one point to another without moving charges from the source), which is completely permitted because ultimately, the energy all comes from and returns to the same place, the active vacuum. So the more kicks, the more potential that can be transferred to our collector coil.

I have more to say but theorizing won?t get the testing done any faster. My present hypothesis is if having the collector coil inside the pulse coil makes any measurable difference in the spikes or circuit output, it will be because of the radiant events occurring from the coil. But again, this all needs to be tested rigorously and verified.

@Otto, I recommend that you bring your pulse width way down from 50%. You can get better radiant results that way and use much less current from your power supply. Just a thought.

God Bless,

@ Otto,
I not have at home the MOSFET you said; I tried with the two MOSFET I have.
The bulb is for 12 volt, so I use 5 volt for the coil.

The setup:

1. MOSFET: IRF 530 and NDP506A
2. 50 turns wire 0,5mm in diameter
3. 5V from power supply
4. pulses from oscillator NE555 5 - 12V; 50% on 50% off
5. trifilar inasulated lamp wire
6. bulb 12 volt 5 watt

Result:

with IRF 530:
maximum bright of the bulb at 10 KHz, with prev.neg spikes of 70 volt; great heat on the mosfet and on the coil

with NDP506A:
maximum bright of the bulb at 5 KHz, with prev.neg spikes of 70 volt; heat on the mosfet and on the coil minimum

without the lamp wire inside the coil I see spikes but no so high, not measured but I think half voltage; bulb brighty the same

If instead I use a neon lamp (18 W 70 cm lenght) I have full brighty at the righ freq. for 1/4 of the lenght of the neon and heat


Otto, and now ? Next step ?
