I am starting work on building a Smith Generator.  Thanks to your work here, I am getting the role of Bucking Coils on the circuit.  I found this link for starters, a pdf that purports to tell you how to build one:  

projectavalon.net/forum4/attachment.php?attachmentid=25399

I extracted another schematic and made it an attachment below.  What they do not mention anywhere in the document is that coil L2 most likely is a Bucking Coil, as you have most eloquently shown here!  I guess they do say it is a "Tesla Coil".  I guess that could be a Bucking Coil.  I have seen similar schematics on youtubes by kdkinen, where he shows his replication attempts seemingly at least generating OU.  His schematics I can clearly see the Bucking Coils.  So with this understanding I think I will attempt a replication.   It seems very simple.  You use a 30 ma NST to get thousands of volts.  The front of the the circuit as shown uses a small inverter driven by a 12v battery to get 120v AC, which is fed thru a variac to control the input voltage to the NST.  The final output is supposed to be up to 8000v @ ~20A DC, as the L1/L2 is 4:1 step-up!   Pretty astounding.

I am not going to use a battery to run an inverter to drive the system.  I will just initially plug my variac into the wall.  You do need a real sine wave input for this.

So the front of the circuit feeding L1 starting with the output of the NST is grounded at the center point tap of the NST.  The output of the NST is rectified to extract the starting HV and then reconverted to AC with a spark gap tuned with resistors and caps to the coil L1 for about 31.5 kHZ AC .

Here is a hand drawn schematic online and in the pdf : Hand Drawn Don Smith Schematic

Hi Sampojoe - This is awesome!

If I may, Don Smith made many videos, but very little actual news coverage, very little anywhere except for the videos.

However, the videos contain really good and very accurate information. Careful counting of the turns, there is a 1 to 4 ratio. This is a common theme in these devices.

My main and best snippet id:

 

The Coil Don marks as L2, is actually 2 Coils. I have fount it much easier to think of them this way.

 

 If one treats each Coil Separately, then one can also measure the Current in each Coil and ensure that the Currents are opposing. By Measuring the Currents, one can view direct improvements. But be careful, High Voltage and Current can damage equipment very quickly!

Don Smith was a big believer in the One Quarter Wavelength principle:

One Half Wavelength:

 

One Quarter Wavelength:

 

I also have seen the same importance, and its also been pointed out by many others before:

Resonance frequencies may be maintained quite constant at high power levels so long as the load remains constant. We are all familiar with AM and FM propagation, where in the case as AM, the voltage amplitude varies, and with FM, the frequency is modulated.


 However, the output power sees a constant load impedance, that of the matched antenna system. If this changes, the input to the antenna is mismatched, and standing waves are generated resulting in a loss of power.

Floyd "Sparky" Sweet - Magnetic Resonance

I have said it before, I am still learning, I will always be a student of Life, I do not have all the answers, but I have seen this importance before. When the right Resonance is achieved, the Coils Magnetic Fields Oppose, the Currents are 180 Degrees out of phase, and excess Power is the "Generated" by the Laws of Electromagnetic Induction. Another of my favorite Videos:

 

I know you have great knowledge in these areas, and much of what I have said is most likely obvious to you, but wanted to try to help.

Don Smith did write one of the pdf documents, I have a copy here: Don Smith

Thank You for your post, please keep us updated!

I am starting to line up parts, figuring out the coil build...  If anyone knows anything about this comment would be appreciated.  

wow Chris, thanks, so much info so fast!  Yes I can't help thinking of the L2 as 2 separate coils also. After all I cannot see something being called one coil when it is wound clockwise for half of it and then reversed to counter-clockwise for the second half!

Regarding your first video snippet, I had watched that on youtube before somewhere, and I thought Don was being somewhat deceptive about it being "one coil with the center cut out".  That would imply both parts would be wound in the same direction, while the essential feature of bucking coils are 1/2 CW and the other wound CCW.  After all I think he would've wanted to protect some secrets so he has a chance of making some money and a living off it ;-)

The L2 coil in the pdf is described as a Barker & Williamson Airdux Coil here.  But again that is indicating its a "one coil" thing.  I suppose they could make those coils CW and CCW, but it would have to be a special manufacture request possibly.  They make no distinction when ordering.  But I will try to build it myself I think.  I would like to use insulated wire as opposed to bare. I can't imagine it would change anything but make it safer.  The oscillation frequency on the L1 would be any high amount that you get by adding in the parts accordingly and then it is supplied by the spark gap, I surmise.  Then the L2 capacitance and inductance would have to be more carefully matched at this 1:4 ratio.

Hey Sampojoe, Agreed. Thanks for the link.

I have reason to believe, and I may be wrong here, but I believe it may be possible that the Parallel Resonant Cap on half of L2, might possibly be a Harmonic of the Primary Resonant Frequency, maybe the second Harmonic.

Don Smith might have been good at drawing Circuits, but he most definitely knew most of the technical aspects about Coils, LC Tanks and Wavelength Theory.

I have said before, and as you already know, some of these devices need to be Grounded, to Earth, and not Negative as such.

In the youtube "don smith seminar on how to make it"  at the 24m mark you can see he holds up PN NPS 12010, which I believe is 120v at 10kv.   I ordered this at ebay, 10000V-10KV-30mA-Neon-Electronic-Transformer-Power-Supply-Rectifier-50Hz-60Hz.  I assume since it says its rectified, its DC output, which will save the diodes & rectification on the spark gap side of the circuit I do believe.

So that would coincide with the 1/4 ratio/wavelength, making it a factor of 4 harmonic?

Hey Sampojoe,

Possibly the 4th harmonic, but this would not give us a very good Current Phase relationship in the two Coils marked as L2.

I believe, possibly the 2nd harmonic, may be better because at the sine at 1/4 wavelength on the second harmonic is a forced function of the wavelengths interactions together, for example, they would be opposite at 1/4 wavelength when in resonance.

This way, as long as the system is in Resonance, the Coil L2 would have opposite phase no matter what, Q would go sky high.

Been a long hot day, am tired so hope this is readable and make a little sense at least?

In the YT video I mentioned above, "Don Smith Seminar How to make it" Don is interviewed for about an hour and discusses many things.  I am sure it is in one of your videos Chris, and there is that wonderful Don Smith YT Channel you've found too.  At the 37m mark, Donspecifically stated that the circuit does not have to be tuned or run at a resonant frequency.  He said that the NST is pumping the L1 circuit as the driver and provides what the circuit needs.  I am parapharsing from memory here.  So I would say the circuit should be built to operate near what the spark gap would provide if tuned, something in the RF range, but is not the critical factor to have resonance, and be perfectly tuned.  So clearly what may be important would be the jagged waveform generated by the sparkgap, the high voltage, the step-up to even higher voltage and the Bucking coils to rip open the zero point energy field.  I am eager to put an O-scope on it when I get something going.

I am moving a little slow on this project as I am finishing up a tesla style DC asymmetric motor first, another couple weeks.  It is a real beast with dual commutators eliminating stupid Edison motor Counter EMF.  I have added in some circuitry to try to reclaim all the energy that should be rattling around in those coils I am kind of excited about and have been working on it for many months off and on...  Its a pretty big motor.  These style motors run at nearly twice the RPM as the Edison style motors.

Hey Sampojoe, re the bit about resonance above, if I may suggest, stay reserved on this. I think this is very important, all my experiments show a Resonance is best. Don Smiths book is titled: "Resonant Energy Systems", so it might be an idea to stay very reserved on this.

Only trying to help, don't want to shut doors before you get to them.

Roger that, reading and listening.  Planning a 3-5kw system with grid-tie capability.  Incredible that the system shown in your pic above, and spoken of in videos listed and covered in the pdf with build directions is supposed to be able to do 160KW, or 8000v at 20 amps!  Figuring components...

having trouble finding the bit in the video you mentioned Sampojoe, did you get my PM?

Don did say:

If youre going to go the Magnetic Resonance route, the world is your oyster.

Don Smith - @40:40 Don Smith Resonant Energy Devices Video - 2006 Tesla Tech

 

We know, we have Experiments to prove this is true, Magnetic Resonance, where the Currents are 180 Degrees out of Phase is very important. One being The Mr Preva Experiment.

I have some points of confusion in mapping terminology to designing the coils in the circuit.  My pdf I listed is calling one or both of the coils a Tesla Coil as does Don Smith in any one of his videos discussing this device.  

  • Is the entire L1/L2 assembly a Tesla Coil design derivative?  Not sure if Don just has extreme familiarity and just never describes the details of the construction, is concealing something, or just expects you to be able to build and hook one up blindfolded.  
  • When I studied a Tesla Coil it was composed of a tower coil with many winds all in the same direction.  The pancake coil was described as bifilar with the two wires connected on one end, and had much fewer turns.  I believe the pancake coil in this construction is the bucking coil because if you follow the current down one wire to the joined end going in one winding direction, the current reverses here and unwinds its way out.  So this L1/L2 construction is the opposite, with the bucking coil having more turns.  Is this analysis correct so far?
  • L1 is the "Primary" coil, where power is inserted, and L2 is the bucking coil, but in the Tesla Coil construction I describe, the pancake , or bucking coil, looks to be the primary.  If this is a correct analysis, it looks like things can be switched around and it all depends on what is needed from the circuit for the desired results, step-up, step-down, whatever.

Hi Sampojoe - If I may clarify, what device are you going to build?

In your original post I thought it was the Early device;

 

But after your last post I am not sure. Can you post a picture of which device you have planned?

Chris posted this 3 days ago

I have just seen the Video you were referring Sampojoe:

 

At the 37 minute mark Don goes into a method I have no idea about. I have not had any luck with this sort of circuit, tried similar things a few time but truly not spend enough time to say weather this works or not. I simply just don't know, for all I know, it might.

The success I have had, are only with the other methods. Mentioned above. Where turns, wavelengths and frequencies are adjusted to get the system to work.

The Image above works, this method is very similar to the Kapanadze work, and also follows closely the work of Floyd Sweet. As well as many others.

Those that want to learn can start with The Mr Preva Experiment, Dom Smith's device shown above, is the Scaled Up Version of The Mr Preva Experiment.

In the below video, watching and listening carefully to what Don is saying when he wraps the Looped Cable around his arm, he describes what we have covered for years also:

Yes I am planning exactly the early unit. I really want to build something a little less lethal, say 3-5KW, not 160KW capable.  I saw him describe a 2KW system for a vending machine & refrigeration unit in Japan.  I am thinking the capacitor bank just needs downsized a bit.  

Concerning the last video posted, I am fairly sure it is the earlier device, identical to the picture posted here, which he started explaining at about the 30m mark.  He is just isolating the L1 at 37m.  

Since I am confusing things with my questions in the previous post, let me ask simply to make sure we understand things, 

Would you agree that the L2 of his early system is a Bucking Coil?

I have found another description of a build on-line for a 2kw system.  I have tried to clean it up with some additional explanations I have added.  It has a nice parts list and explains power transmission on the L2 nicely, but it looks like the 160kw early system.  I am going to try to attach it and my original document also for readers.

I want to make this a grid-tie system.  So the question is how to get from ~8000vdc to 12-48vdc.  I am thinking I should not rectify it, but maybe step down the AC voltage first with a transformer, just keep stepping it down until I get it within range for a particular grid-tie inverter.  

Chris, do you think I could insert a step-down operation without breaking the circuit? or maybe not going 4:1 but maybe 3:1, after all I only want 3-5KW.

WOW, if I may suggest: "Little Steps for Little Feet" Start at the start and work forward. Compare what we have talked about already, learn what the requirements are, study, first.

I am a firm believer in hard facts. Perhaps the following snippet, applying the Right Hand Grip Rule, will answer:

 

I also think the last video I posted, with the Looped Cord, wrapped around Don's arm answers this question. Don does say several times, mentions "Generators" and how the Fields oppose.

I would stick to the known facts, not diverge at all, go with what you know to be true.

Then apply known laws of Electromagnetic Induction and expand that just a little.

Chris, do you think I could insert a step-down operation without breaking the circuit? or maybe not going 4:1 but maybe 3:1, after all I only want 3-5KW.

Again, I would not change a thing. Keep everything the same. Throw a bunch of incandescent Bulbs on the end like in the Videos.

I was late to the table with Don Smith. I did not intensely study until well after all my research with Floyd Sweet. I spent a long time proving things wrong, chasing red hearings, and in the end spending a lot of money where I did not need to.

What happened to me? Over night I evolved. It clicked, my small, basic very simple experiments paid off. I learnt about Electromagnetic Induction, carrying a Magnet and Coil around all the time while in the Lab, the coil was always short circuited, and always the coil would expel the Magnet, always appearing to be a greater Magnetic Field from the Coil than from the Magnet. But why?

Time Rate of Change.

Don Smith is spot on! On occasion he may not give the best information, perhaps he did not like the other person. But Don's basic layout and how it all works is spot on! We have proof, we can experiment on the bench and prove what he says to be true. It may not always be easy, but it does work as stated. The Mr Preva Experiment proves what Don says to be true, Floyd Sweet proves Don to be true.

Primary, 4 Turns, Secondary 17 Turns, then Centre Tapped, and Tertiary another 17 Turns, the Tertiary opposes the Secondary, the Secondary Opposes the Primary and the Tertiary assists the Primary, so: 1 + -1 + 1 = 1

What's the End Goal:

  • Amplify Voltage
  • Amplify Current

We do know how to do it, the very simple steps are laid out. Its just a case of following the guide. Lay out the Plan and stick to it.

Hey Sampojoe - Why is a Common Mode Choke not OU? What's the true purpose, and what does it truly do?

There is a few reasons, but one in particular I am looking for.

Why do we have a Power Correction Ratio, or a Power Factor? What's its purpose?
