Open Source Project for Tesla/Jackson Wireless Transmission

I just had a thought.

Is there any reason I should not connect the negative of the primary to the negative of the secondary and ground ? Because if I do that I think I would be pumping a lot of energy into the ground.

I am collecting the collapsing field to charge another battery, but if I disconnect it the protection neon fire's, I think if I connect a ground there it will stop the neon fireing but that seems like a waste. Or is that part of the effect ?

Do I need to get higher voltage Mosfets so they can take the field collapse without a recovery battery or ground connection there ?

The charging of the second battery is very good with particular setup, but that is not the goal. It seems wrong to collect the collapsing field with this.

Any thoughts

OK now it's working, at around 50 Khz i can get over 40 volts at the receiver. Light's LED's no probs. It even blew a 5mm LED. The cap I had on the AC was blocking the energy.

I'm still using the aluminium plate for a ground, just laying it on the concrete it isn't even clean, one side of the plate is still covered in plastic.

Anyway what I did was connect the primary negative to ground with the secondary on the transmitter, a "real" ground, then the receiver I use the metal plate layed on the concrete, the LED is the same brightness even if the receiver ground is connected to the transmitter ground or not, must be what he say's is an inductive relationship with the ground ( same thing that ruins batteries if they are left on the ground). And I removed the recovery battery. Neons light from the toroids no problem now.

With about 50 Ma input I can remotely light an LED from the receiver output at pretty much full brightness.

Under load with 1 x 5mm LED ( that's the only LED I have left ) the transmitter toroid reads 2.5 volts AC and the voltage across the LED is 2.94 volts. Which seems like good transfer considering they do not share a ground connection and 50 Ma @ 12 volts input..Care must be taken when using caps on the receiver output because the voltage keeps rising to about 50 volts with no load, that's how I blew the LED.

The effect is there resonant or not so I am very happy. seems to me they work like a step up and step down transformer connected but they are separate.

On second thought I think the coupling distance on the primaries is just fine. As Nikola says these things can be adjusted for our own personal requirements, the coupling distance the number of turns the thickness of the wire the input voltage and many other things could be changed in differing cominations to acheive different effects.

I can't wait to excite it at it's resonant frequency.

The number of winds in the secondary would really be dependant on the distance it needed to transmitt. I think Nikola talks about that.

After I have a sleep I'll make a video showing how I have it working. I never would have thought I could build a Magnifying Transmitter in three days.

I went to shoot a video but the battery was drained, so here are some pics instead. I ended up just putting a choke on the recovery to the second battery, I did try grounding the primary negative but that was wastefull, it's funny but with the choke it only just charges the battery but it makes the led brighter and the neon is brighter when touched to the top toroid. With nothing there is ok but I found this is better with than without.

Setup on floor with ground plate only for the receiver.

This shows the tuning capacitor, series inductor, recovery choke and circuit arrangement, I went back to an old circuit for fear of ruining my new one.
http://wv0v9q.bay.livefilestore.com/...002.JPG?psid=1

When I light a neon on the transmitter toroid it dims the LED a bit.

Exciting the neon through the glass.
http://wv0v9q.bay.livefilestore.com/...008.JPG?psid=1

I'll make a circuit drawing soon of the setup, I am using now a 320 uH inductor and the cap is at full turn at 1300 pF. Running at 50 Khz for these shots. I think I need another 300 to 500 pF for the transmitter cap I'll try the other one the same with it soon.

I wonder what will happen when I connect my toroidal transformer secondary to the transmitter primary with shunt caps between.

Ok I made a video and finally got it uploaded.

YouTube - ‪Transmission Test - 1.wmv‬‏

I've already managed to tune it up to 76 volts at the receiver output ( open circuit ).

Cheers

[cody]

Looking good! Looks to me that your still not in tune though. These coils are very sensitive once you get them in tune, just putting your hand by them will knock them out of tune and you will see the load drop off when you do. I suspect that your square wave is giving it enough of a ping to get it ringing a little bit and your receiver is picking up the HV field. Try separating the coils at a greater distance like 5 or 10 meters and see if you can still get anything with the plate and/or ground wire. Distance effects the tuning slightly so you may need to make adjustments.

[Farmhand]

Yeah I will need to use Mhz to get it into resonance. I can only play for now but I can learn some things. Putting my hand near it does afect the transfer but I have to get it within a few inch's.

Yeah today I make a base for the receiver for testing the distance transfer.

I am using a square wave but it isn't 50/50. Rectifying and storing the output is proving to be difficult. I have an idea from the testatika machine, U shaped magnetised transformer core's or just a steel core transformer might work.

I guess when the transmitter is in resonance the receiver will output a sine wave so that will be much easier to use than the scratchy wave's at the receiver now. An Ultra fast recovery FWBR might also help with storing the output.

I am thinking my Bob Boyce transformer might be good to use on it if I construct a resonant AC tank with series inductors and caps. It will idle with very low standby input and the output is kind of AC but I have it pulsing about 18 times at 2 us then a pause to the next group, could be worth a look for the fun of it I should maybe reconfigre the controller to three phase (three single pulses).

This is what the waveform from the secondary of my transformer looks like. I can make it so there is no pause and all 2 us pulses with 2 us between, well I think I can. However if I reconfigure the controller to three phase I can tripple the effective frequency and hex it if the output is AC.
http://public.bay.livefilestore.com/...006.JPG?psid=1

What happens if I use AC to excite the primary ? Is it better or worse than DC for the primary power ?

Anyway I have to cut MDF boards and paint the edge's. But it is raining all weekend, looks like. I have to stoke the fire to dry the paint. The way I mounted the tall former was I screwed a pill bottle to the board and the pipe slide's onto that.

Cheers

[Farmhand]

Hi Cody, you were right about the ground connection when I put this cap pulser on the receiver output I got just 65 volts on the cap with the ground plate only, but then when I connected the receiver ground to the actual ground connection I got over 95 volts. The discharges in the neon are affecting my computer and making it make the sound of disconnecting a USB device every now and then.

I can't cut boards because of the rain. When it stops I can do it.

Here is a video clip of the 4.4uf neon fired SCR cap dumper working from the receiver.

Magnifying Transmitter Prinipal ?

Anyone ever think about the Magnifying transmitter like this.
http://wv0v9q.bay.livefilestore.com/...002.JPG?psid=1
I just fixed the drawing, I left out an arrow.

I think I am seeing a feedback from a power surging the receiver seems to send back any excess potential it has to the transmitter to equalise thier potentials. Interesting.

Here is a circuit I dreamt up for the receiver, craziest circuit I ever drew.
http://public.bay.livefilestore.com/...001.JPG?psid=1

[Farmhand]

When an atmospheric electrical discharge happens there is a rapid exchange of energy back and forth through the discharge stream.

These two pictures are frame's from a video, I captured them to show the Power Cone, we can only see the cone above ground the inverted one. It's opposite would be below ground .

Phase one.
http://public.bay.livefilestore.com/...s-1.jpg?psid=1

Phase two.
http://public.bay.livefilestore.com/...s-2.jpg?psid=1

And this is a supernova. It is obvious to me these are similar. The supernova picture is taken over a long period of time, so the oscillation cannot be observed.
http://public.bay.livefilestore.com/...250.jpg?psid=1

It is the way of the Universe to swap energy back and forth for eternity for free all losses are recycled immediately no one has to pay the Universe for a lightning strike to take place, and yet they do. The lightening actually looks like oscillations in a big LC Tank circuit if you turn you're head the right way.

It all looks a bit pyramidal and vortexian to me.

The Magnifying Transmitter would have an AC oscillation from top to bottom wouldn't it ? And with an identical Receiver they would have a longitudinal oscillation between them at the top through the air and also at the bottom through the earth and the Receiver would also oscillate with AC from top to bottom.

So we would then have a four way oscillation, all ways trying to equalise but can't.

Pure Genius. Tesla impresses me more and more each day. His name will become almost immortal and he with it.. Through sheer hard work in one lifetime he acheived it, that is very impressive. I have no doubt that in 1000 years time if civilised man still walks the earth Tesla's name will be spoken.



Edit I'll just add this video clip link here.

I prefer using AC for these small tests, you get twice the voltage on the primary that way. Even better is AC square wave, that will smack it real good and get an even greater voltage gain on the secondary. Also with AC you can insert a series capacitor with the primary to form a series tank circuit and that will ramp up the voltage on the primary much higher if designed correctly. But your setup seems to be working real good, Im not really familiar with the circuit you are using but it appears it is inputting a higher voltage than the 12V battery you are running with. Have you measured the voltage it outputs to the primary? DC setups in my opinion seem to become advantageous for overcoming the engineering difficulties of getting really high voltage onto the primary at high frequency. For your recovery on the receiver try to hunt down some 1n4148 diodes. You can usually find them in junk electronics, they are very small and glass. I find them to work great for these little setups.

Ok done some reading, here.

Comparative Study of the Tesla and Marconi LF Wireless Systems

Interesting Quote's from the page.

Power supply waveform

Hertz/Marconi system: perfectly sinusoidal AC at oscillator frequency

Tesla system: dc pulse or square wave at oscillator frequency plus low frequency impulses of great intensity and short duration.

I reduced the number of poles, I think, in 1901. But then I reduced it for the purpose of generating currents of higher frequency. If I had a great number of poles, I could not realize my idea, because these poles would come in quick succession and not produce a rate of change comparable to the rate of change which is obtainable by the discharge of a condenser owing to a sudden break of the dielectric. That is to say, a blow. It has to be a blow, you see. I had to place my poles comparatively far apart, then run them at excessive speed and generate comparatively few impulses, but each of those impulses are of such tremendous intensity that the dynamo is practically short-circuited. That gave me a blow which replaced the arc. . . . [NTAC, p. 15]

Excitation of propagating medium

Marconi antenna / half-wave dipole, the electric field energy and the magnetic field energy are introduced into the field medium in time-phase with each other. The excitation of the medium by the antenna develops an in phase propagation mode shifting to a quadrature phase propagation mode, this taking place over the initial range of transmission; Fresnel zone, also called the radiating near field. The launching structure provides a good initial impedance match with free space resulting in the efficient production of electromagnetic waves.

Tesla antennas, electric current in lower half-space; TM surface wave, spiraling electrostatic and magnetic flux lines in dielectric portion of upper half-space; electric current and magneto-hydrodynamic waves in ionized portion of upper half-space. The launching structure is specifically designed to have a poor impedance match with free space. Its configuration inhibits the launching of electromagnetic space waves. Provided with sufficient input power, a large magnifying transmitter is capable of ionizing and breaking down the denser insulating portions of the earth's atmosphere around and above it, rendering this medium electrically conducting.

In Tesla’s system the transmitter and receiver are interdependent. The transmitting element consists of three sub-elements, a single coiled wire conductor—a helical resonator—possessing inductance, and two conducting bodies of large surface area in relationship to their greatest linear dimension, which have a mutual electrical charge storage capacity. One of these bodies is the elevated terminal positioned above the resonator. The other body is the earth itself. The receiving element also consists of three sub-elements, a helical resonator and two conducting bodies of capacitance, one of which is an elevated. As with the transmitter, the other body is the earth. It is this common conducting body, which forms the ground connection between the transmitter and receiver through which alternating electric current flows. The other connection required to form a closed circuit is through the air by electrical conduction in plasma and electrostatic induction. The movement of energy is in both directions, from the transmitter to the receiver and visa versa.

Looks like a sine wave input is out of the question.

Yes an AC square wave is appealing, but really high frequencies may be easier with DC.

The circuit I put together is basically Tesla's Ignition coil patent drawing modified for the transmitter, the only change is the transformer.

Tesla Ignition coil patent
NIKOLA TESL-A - Google Patents

My circuit. is the generator side of this.
http://public.bay.livefilestore.com/...ver.JPG?psid=1

If the cap is sized right the inductor discharges into the cap and charges it to above supply voltage. Then the cap discharges through the primary coil. I am trying to discover the cap inductor values for this primary, I think I am close. I tried measuring the cap it said 11.5 volts, I think this is a current amplifier because the cap is in parallel with the inductor. The energy stored in the inductor gets added to the supply but I'm not sure of the actual mechanics of it I have yet to determine that, but it is very effective.

I drew it for a spiral transmitter, before you guys showed me this one. Which I think is the better design. Especially for no spark gap because at this time I think he was just using abrupt switching as in the quote in the post above. Hence the closer coupling. i think, i need to read more.

Cheers

I wouldnt say that. The high frequency alternators used by Marconi were actually tesla's invention. They later became known as alexanderson alternators. Either way they were teslas design and he used them a lot for his wireless system. But yes, for his final design he did say he preferred using DC, but either will work. My main reason for suggesting it is because i think its the easiest way to really comprehend how to tune the system and how different things you do effect the tuning. Personally i have found a function generator with a built in frequency counter to be the best learning tool for understanding tuning of the system. I had built oscillator circuits and ran many tests like you are doing and thought i understood the tuning, but it wasnt until i got a decent function generator that i really got a grasp on it. But thats just me.

I looked at your circuit again and it looks to me like a DC resonant charging circuit except you are using a transistor instead of a spark gap. Thats an interesting idea, i like it. I wonder if it would work better if you put in a de q-ing diode between the battery and the inductors. Here is a typical DC resonant charging circuit. See the first capacitor after the bridge rectifier, that is basically your battery. If you add the diode it shoud ensure that no current flows back into the battery before the transistor fires.



So it would look like this:



If you want to read some of the theory of the circuit and why im suggesting to try a diode you can read here:

Hi Guys! I'm interested in replicating the wireless power transmission, but i have no function generator or even a oscilloscope. Right now i'm searching for a variable 4MHz to 10MHz square wave generator schematic that would fit in, or any other oscillator that would work for this project. I was looking here: Square Wave Generator
Does anyone know if this is suitable for such frequencies?
Also, could someone more experienced than me draw a schematic for let's say a 10W or 20W output?
Or can i get any advice about this idea like what transistor to use on the output of the oscillator?

Thx in advance!
