Sharing

Hi Mike.

I might have started this thread but do not claim ownership of it, and from what is obvious, members of this energetic forum are great sharers anyway.

I build only where I have a prior idea to test, and this is why I have never tried anything related to Mk1-2 Hendershots, not even any failed investigations. Hence I cannot help you any in this regard.

Look forwards to hearing of any conclusions you might make though.

Cheers ......... Graham.

Ok.. so Im definately not an electrician... But I stumbled upon a set of plans for the Hendershot Generator...

First off, the hand woven coils state you should have 57 pegs... is this number crucial?

Secondly... I have been thinking of using a neodymium magnet for the "core" of the unit.. I know these magnets are VERY powerful... any thoughts on this? Or should I stick with a regular steel magnet?

Third... there is no mention of a 4th wire in this design.. I dont know what else to make of that.. but I will attach the schematic drawing for you to have a look at.

Last is about the capacitor and transformer rating.. The only info I have about these components are as follows...

2 X unpolarized capacitors 500 micro farads each
4 X unpolarized capacitors 1000 micro farads each
2 X Transformers 1:5 ratio for 110-240 volts

Hi XXXJAYXXX.

57 pegs ? I do not see how this can be critical. The idea with a basket weave coil is to reduce interturn capacitance without much reducing alternating magneic field coupling.
I believe the most important aspect was to construct self supporting windings in order to be able to insert or replace separately constructed corecaps without need for destroying coils in order to do so.

I do not know enough about neodimium magnets.
Magnets 'ring' and impart same waveform characteristic within any coil or mechanical coupling arrangement when constituting part of a pulse energised magnetic circuit.
Alnico types do not ring as much because their cores are conductive, thus the coil current to mechanical/ armature transduction is more direct.
This is the reason older loudspeakers with Alico magnets remain better to listen to than modern types having higher power ceramic or ferrite type magnets.

Fourth wire ? What fourth wire ?

Capacitors - non polarised motor-run types are available, if expensive.
Where do those capacitor values come from I wonder. Unless any output is low-Z and at least 1kW then 1,000uf is like a short circuit to the Hendershot arrangements. Maybe someone has missed out a decimal point before each last zero ?

Transformers. The TV frame output transformers Hendershot used were quite unlike transformers still made today. They were more like audio transformers with 1k primary and 40 ohm secondary matching impedances, also with gapped E-I cores to reduce core saturation. Mains transformers would not have as finely grained laminations, nor paper gapping within the cores, so any mains transformer substitute would need to be much larger in order not to saturate at the low running frequency, and be toroidal in order to have an improved HF response.
Mains transformers today also tend to have laminations that are side welded whilst having been under pressure. It is possible to hacksaw through this weld and insert a layer of paper yourself (I have done this). Windings on mains transformers also tend to be bobbin separated for insulation purposes. This is disadvantageous for HF coupling; however there is no reason why you could not then wind your own layered transformer after sawing a modern component apart.

Anyone who wants to replicate a Hendershot generator today is going to need to overcome many more obstacles beyond incomplete/ inaccurate circuit records/ instructions.

but don't let that put you off ........... Graham

Yes, there is not any complete instruction set left anywhere; TPTB ensured that !

My conclusion - Lester was very clever, and for all my efforts, I don't come close.
I certainly have not been able to suss out the Mk1-2 versions.
I did however think that tin wings were the 'antenna', or at least a differential capacitor tuning the first set of inductors with respect to the capacitive free space coupling of all the other wiring. Also that the resonance effect was vibrator pulse tuned.
So: Slowly - Slowly -

Cheers ........... Graham.

@Graham,
Thanks for the response, I wasn't sure anyone was still posting here based on previous posts. I agree with you about Lester being very clever. A lot more clever than any available information has provided. I think I want to try my hand at the MkI/MkII, at least for awhile. It sounds like you have attempted this with no success. With the lack of basic information I will more than likely fail as well but you know, you just gotta try. I was wondering if you would be willing to share some information on your failed builds. I could start my investigation from scratch or I could save some time by using some or yours.

coil size, wire size, turns tried, etc.

It does not need to be everything you tried but a starting place. Please post here or PM me, thanks.

With the information given, Hendershot used an old radio given him to build the first version (I am sure he had lots of spare stuff around as well, we all do).

@all,
This seems like as good a place as any, So, I have decided to post my findings here if that is OK with the owner of this forum. No posts here have given any specific information about any builds yet. I don't know if this is the right place. I know that there was an older forum for replications of Hendershot but it seems to be unused at the present time. Let me know where build information should be posted.

Noob Q's

Ok.. so Im definately not an electrician... But I stumbled upon a set of plans for the Hendershot Generator... complete with instructions on how to build one.. After seeing it wired on video.. this does appear to work... However.. Im not very tech savvy and have a few questions..

First off, the hand woven coils state you should have 57 pegs... is this number crucial? I counted the pegs on the picture in the instructions.. and there appears to be 60.. and after laying out my circles in even geometric proportion I wind up with 63 pegs.. Just wondering if this is ok? or is it giong to throw things off ?

Secondly... I have been thinking of using a neodymium magnet for the "core" of the unit.. I know these magnets are VERY powerful... any thoughts on this? Or should I stick with a regular steel magnet?

Third... there is no mention of a 4th wire in this design.. I dont know what else to make of that.. but I will attach the schematic drawing for you to have a look at.

Last is about the capacitor and transformer rating.. The only info I have about these components are as follows... perhaps someone could shed some light on what combination of microfarad and voltage I would be aiming for.. They call for:

2 X unpolarized capacitors 500 micro farads each
4 X unpolarized capacitors 1000 micro farads each
2 X Transformers 1:5 ratio for 110-240 volts

I am hoping to build a 110v system if that helps at all... Any info would be GREATLY appreciated!!!
I will attach a schematic of the device I am trying to build.

In this movie, one could see how a single pulse accelerated the spontaneous magnetization.

Yes a molecular 'magnetic domain' (atom electron spin-orbit alignment) wave development, via progressive quanta share-triggering process, like Barkhausen.

After reading all of the material and the posts in the forum I have come to the same conclusion as both Chris and Graham.

Yes, there is not any complete instruction set left anywhere; TPTB ensured that !

My conclusion - Lester was very clever, and for all my efforts, I don't come close.
I certainly have not been able to suss out the Mk1-2 versions.
I did however think that tin wings were the 'antenna', or at least a differential capacitor tuning the first set of inductors with respect to the capacitive free space coupling of all the other wiring. Also that the resonance effect was vibrator pulse tuned.

Presently I am about to try experimenting with Mk3 replications.
Unfortunately my Geiger Counter recently passed away through old age and I am trying to purchase another.
Why a Geiger Counter ?
Well I suppose I could use a radio or headphones as Lester and Aho did to detect the onset of operation, but listening for and to EM inductions/ radiations is not the same as detecting the atomically reactive output which sustains output.
Also I have no wish to harm myself or anyone else through radiations which might extend beyond magnetically coupled inductions.
So: Slowly - Slowly -

Which version - MkI or MKII

When searching the web I only came across 2 pictures of model airplanes that were associated with Hendershot. One was mounted on a wood stand and the other picture was of Herdershot and his son holding the airplane. After looking at the two pictures I have concluded that the mounted airplane is the MkI version and the other picture is the later MkII version. The MkI version was a toy. By looking at the picture you can see it was made of metal (tin toy) with a modified front end to house the motor. The propeller is too small to be of any use and the wing span is too short. The body seems a bit long as well. This picture shows a very good model building skill of Hendershot. It was nice of him to leave it open so we could see what was inside. The second picture is very bad and it is hard to see any details. But the propeller is bigger and mounted on a pointed nose cone, the wing span is wider and the body length with both Hendershot and his sons hand holding it seem to be in the right proportions as the one that would have been used as the demo airplane that does not need to be in the North/South direction to work.

Claiming that the difference between the MkI version and the MkII version was only within the basket weave coil then we can assume that the apparatus for each was really close. I don’t think that after mounting the MkI version he would take the guts out to build the next version. He had time to rebuild and make the second version work as he claimed, any direction, leaving the first version still mounted and at his home (where is it now?). The first version MkI seems simpler as it relates to the induction compass and I don’t care that it only works in one direction.

Second Thoughts

From the information available Hendershot under other occasions build projects (toys, etc.) that he sold to companies, I could see him selling the information for the MkI/MKII for $25000 (a lot of money back then) and walk away saying that the project was a fake and never talking about it again. I can see him signing a NDA (or what ever they had) to not create another one for the seventeen years of a standard patent. I believe that the MkIII was a result of his commitment and why it took so long for him to expose another version that is a lot different.

First Thoughts

After reading all of the material and the posts in the forum I have come to the same conclusion as both Chris and Graham. This apparatus has some very interesting background and discoveries. I have decided that I want to start in the beginning. The MkIII seems to have to many schematics and for a start project way to hard to get it to start running. Even though to build it looks simple. After Ed Skilling took a working model and disassembled it and then reconstructed it plus built a second one to the exact same specs, he could not get either one to work. He then took it to Hendershot and it still took awhile for him to get them to work again. Where as the MkI/MkII model, from the information available seem to work without any trouble. Hendershot's family didn't seem to have any problem playing with the airplane that Hendershot built plus other appliances when Lester was not around. After the airplane demo the air base engineers under Hendershot instructions (hands off) they were able to build a very large 45 - 60 HP version that seem to work without any problems. The MkI/MkII, I think is where I want to focus first.

An experiment that was performed in tel-aviv university in Shimshon Bar-ad lab by Moshe Elazar .
In this pump (high intensity beam) -probe (low intensity beam) experiment at a fixed magnetic I did an excitation on permalloy with single pulse (pump) and used a kerr microscope and a probe in order to record the changes (with CCD camera) in the sample magnetization as a function of time.
In this movie, one could see how a single pulse accelerated the spontaneous magnetization.

Toy Airplane

Are there any other photos of the toy airplane besides the one side view. I was wondering if the model was a tin toy airplane. The strut that goes for the wing to the body looks like thin metal (tin). Do we know if this is a custom toy or a modified purchased toy. Just curious. I love model planes and these old ones are very pricey.

I expect to have the resonator strip assembly completed today, and initial set-up underway by the weekend. Stay tuned!

Looking forwards to seeing your resonator Chris. Likely beyond what I could fabricate.

This video shows nicely how a wavewound coil is fabricated -

and this patent is quite Hendershot motor like, though in reverse !

Thanks for the insight

I am not sure yet what version is more interesting. Like I said I do have a MkIII schematic with hand written notes like, "capacitor C2 equal to .0062, squeeze with clamp to work, variation of pressure raises value to .01 from .0062". I believe that the circuit was currently being tested. But the idea of the MkI version that can be created any size, in the small airplane or connected to a 45HP motor of 130lbs. I must read for awhile and there is a lot of it. Thanks for the insight, this should be fun.

The name of the article is "Electrostatic Power Generator" that contains only page one and a schematic that is dated Oct. 26, 1958, signed by someone named ES... Sunday 11:30 to 2:30pm. The title on the schematic page is "75 watts output, Meter read 110 volt AC, after 3 min. drop to 90 volts and capacitor starts boiling".

Hi Mike,

Looks like you have a good original find there, for electrostatic is indeed the C1-2 feedback mechanism which maintains generation, yet I do not remember reading this anywhere else.
This was the main reason for my last post, for Barry's 'Mystery' text stating construction of C1-2 will negate electrostatic transduction, whilst Mark's 'Archive' published drawings are correct, as per that last link I posted.

If a capacitor boiled then clearly there was more than enough power generated than that necessary to merely light a lamp, and obviously this was why so many variants existed as the circuit became more developed.

I concur with Chris too - for here there is indeed need to read all texts in order to get a feel for Lester's constructions:
His works were entirely intuitive and yet he 'real-world' demonstrated (what all the scientists said was and still ensist is) the impossible.

Cheers ......... Graham.

PS.
Presently Chris is studying the Mk1-2 versions, myself more the Mk3 variations.

MikeC,

Read them all, in no particular order. As you do, bear in mind that: (1) an electrical current also has a magnetic component at 90° to current flow, (2) that the field of a permanent magnet can be cancelled out or made stronger with a coil wrapped around it, and (3) as Hendershot stated, if you use your finger to physically move a compass needle to the east/west position, it will return to the north/south position when you let go of it. There's no "magic" or "mystery" here. Be child-like in your thinking (as opposed to a totally brainwashed academic who is incapable of thinking outside the little box his professors created for him) and it'll become clear how the Hendershot device works. Start at the beginning as Hendershot did. Pay particular attention to what happens ELECTRICALLY when you make/break a MAGNETIC circuit -- which can happen in a wire even WITHOUT an electrical return path.

Best wishes in your endeavors.
Chris

A little help - Just starting

I ran across the forum with a name something like "get 5 out with 1 in ..." and started to read some of the posts. I read one post that had a schematic of what I have come to learn is referred to as the MkIII version. I noticed that it looked like a schematic I have owned for about 30+ years (I was really young when I got it). I couldn't tell what the name was except that it was something like ES... . I have periodically tried to look up this name but with no luck. I guess I didn't try that hard. The article I have is incomplete so I never bothered to do anything with it. The name of the article is "Electrostatic Power Generator" that contains only page one and a schematic that is dated Oct. 26, 1958, signed by someone named ES... Sunday 11:30 to 2:30pm. The title on the schematic page is "75 watts output, Meter read 110 volt AC, after 3 min. drop to 90 volts and capacitor starts boiling".

From this forum I have found the name of Ed Skilling and decided to find the the above papers. After about a week of searching I found them and in fact the name on the paper is E Skilling. I have always wanted to build this but had no information of any kind. I want to make this my next project but from what I have read in this forum it almost seems that at the present no one is doing much. I have download a lot of PDF files and I'm happy to see that new posts are still being made here.

Can anyone give me an idea of what is the good/bad and the ugly of the PDFs that I have found or where I should go to find out more. There are lots of web sites out there but I am going to stick with this forum until I get more knowledge under my belt about the Hendershot apparatus. I am starting with PDF #6 above, but if you have a better order or other PDFs I should read first let me know.
