This is it !

Hey, no problem man. I took an early interest in the TPU, but it seem clouded somehow. I've got only one video of him (Steve Marks) where his head/face is showing and plus, verifiable information is scarce to say nothing of PesWiki unflattering review of Marks by his associate (whatshisname).

I don't recall much of what I read on the Mark TPU, save that it appeared to function in a manner similar to the advanced mode that Boyce claimed with his own toroid. Due to, as you point out, a dearth of information from some of these guys who are living today, I've focused the bulk of my research on what Tesla was doing, as there is a lot of literature by him on his work, and he's got a proven track record (don't think for a second that oil and other interests won't put people out there with convincing claims to divert out efforts).

Amazingly, I only recently took an interest in Tesla. In Ch XXIII, his toroidal (converter) and polyphase work shows the common thread running throughout many of his creations, I think I see, in Fig 94, are those nine (9) spark gaps (or are those symbols for something else ?) bottom-center and bottom-right ?

Those are all loads. They are described as lamps in the text, which may be a little confusing because of the mention of the term "arc" in the same sentence. I think those aren't labeled well as some one else appears to be writing/narrating at that point. Tesla labels every thing in actual patents, so don't hesitate to grab those for reference down the road, even if you don't have time now (I know it's a ton of reading!).

Based on this, should we be pulsing multiple windings on a (choice) toroid using UNsynchronized free-running oscillators ? ... this is easier to do than 'synching' several circuits to some cadence like 1-2-3, 3-1-2, 2-3-1, 1-2-1, etc... and should we have a primary (secondary-teminology), (other winding) to 'potentially' do something with and should that be providing 'gain' and if so, how much?

I'd stick with one toroid and winding for now. The winding is a pain. Multiple windings will be useful for experimental purposes but just try to do one thing at a time. I dove in head first with the Boyce design so I can't really say I followed my own advice, but this is my opinion from experience at this point. Synching several circuits would be a nightmare from what I've heard through others who have better traditional training than me (self-taught over here ).

I literally used one large 6.5" inductor for making the spikes, and then I used capacitors around the FET drain and source (the point of break), as Tesla did with his spark gap, to allow the inductive spike alone, to pass through the caps, to a second inductor 1"-1.5" in diameter. This second toroidal inductor had the primary and secondary wound as a 1:1 (8 or 9 turns each) relation. On the secondary I placed a rectifier and a pF or nF home made high voltage cap, in parallel. Attached after this was a test neon bulb.

I really need to dig up my old posts on the closed forum with these details as there are a lot. I also drew up a diagram of the circuit which is easier to understand than all this babble. At any rate, I literally copied Tesla's high frequency current patent 568,176 , but I used a solid state pwm in place of the disruptive discharge portion of the circuit (that is the capacitor and spark gap combined). Give me a few days to try to dig up further details as I have a visitor here until Sunday, and I'll want to possibly format and clarify things.

This area of work by Tesla is literally the holy grail that every one wants. He probably figured out even more that he did not publish simply due to him getting shut out of academia, main stream science, and commercial production after he gave the 3 lectures which are listed in that book.

Patience and perseverance!

One of tesla's first inventions after arriving in America was an improved form of "arc lamp."

You are a goldmine of useful tesla patent numbers. Thank you.

Thanks for the clarity on the drawings.

So, did your 568,176 work to produce the effects you sought ?

I've downloaded that patent as well as its two predecessors.

I will take your advice and shoot for one X one on the toroid X coil. The wires can always be stripped and rewound and/or replaced for future revisions. Would it be of any value to begin by pulsing a metglass-cored standard-designed transformer just as a first look, or do you feel that the toroid is the ONLY viable transformer species for this research ?

I know that Sweet's (VTA), Bearden's (MEG) and Naudin's (apparent) successful replications of these devices did not use toroid xformers or even exotic materials ... except for Sweet's magnets and their conditioning and orientation(s) (which after viewing the materials I purchased from Bedini/Bearden, I concluded was useless .. bad investment).

I built the op-amp based impulser mentioned earlier in this thread. It looks very promising. I am going to hook it up to the Stingo next to get sharper, higher voltage impulses. Sharp, high voltage impulses without a spark gap is going to be great!

YouTube - Op amp based impulse generator

Hi, 7imix, could you attach copy of this impulser circuit and designate
how you hook external components to it, especially stingo ? I made it
and i play with it pretty much time, but i am still confusing about some
details...Thanks in advance in the name of all of us who are going to
benefit from your help !

cikljamas, I'll try that circuit tonight, is this the one you mean, it has two batteries ?
No certainty, I could get distracted, i'll try, good practice for a beginer like me. Is it a "Stingo" if it is he looks funny.

Farmhand make simple stingo, forget this 555 circuit, i gave up from it
since Sucahyo wrote that it is not self charging stuff at all...
And when you make it go ahead with questions !
Rgds !

[Farmhand]

Hi all, I failed with Stingo last night, i'm short a couple of parts, lots of farmwork today, try tonight again.

Stingo might be able to play this instrument it looks funny but who knows it may be worth a try, secondaries can go between maybe if you want no need I guess. I don't know how many turns really needed. Should be easy to wind neons in series maybe pulsed by stingo coil to this coil maybe use straight on stingo with no neons. I wish I had time to try first.

Cheers all

Here's the op amp impulser circuit I am experimenting with, and how I am experimenting with mashing it to stingo. This is still very much a work in progress, but it gets some interesting results.

I'm currently driving this with 5 volts. The light bulb in the circuit is just a small bulb.

I need to modify the op amp part of the circuit so that the frequency is adjustable, otherwise this is pretty useless...

Note that when using this with the stingo the duty cycle actually has to be as close to 100% as possible instead of as close to 0% as possible, because of the PNP transistor.

It just occurred to me that having the regular stingo potentiometer feedback from the end of the coil to the base of the PNP may help the impulse shut off faster. If it doesn't destroy the op amp.

Please share any interesting schematics of this that you have come up with too...

Thanks 7imix !
I did similar thing PWM to PNP base (tip 2955) but across another toroid
and it increased a little bit effectivity of stingo but after that i noticed
that if i just put my second toroid in parallel with my first toroid which
is hooked to FWBR it increase even more effectivity of the stingo...
But it seems that you do not use stingo as a whole, but just part of it
Am i right ?...Or you just didnt draw whole stingo ???
I do not have oscillator so i cant see sharpness changing of the wave,
that is why i thought that something is maybe wrong...
But i am still not sure if everything is ok with this VIN, maybe this 2kohm
which goes to the ground can help, i suppose that i should here changing
stingo frequency when i turn that pot. before VIN, but i do not here changed
sound of frequency, but if i put pot. instead R3 (10 k) and turn it there is
changed sound of frequency...
So, to repeat once again : Is that stingo drawing on the right whole stingo
that you use or just part of it ?
Thanks again !

The potentiometer I have in my circuit changes the pulse width. I did not install a pot to change the frequency of the op amp impulser yet. I will try putting a pot instead of R3.

Yes, I'm just using part of the stingo... I left off the potentiometer and resistor that connect the coil to the transistor base. I will make a video soon.

For working with the stingo and other impulse circuits, I highly recommend getting an oscilloscope... The DSO Nano is only $80, although I understand that might be a bit expensive for some people. It's totally worth it though.

Nice JOB!!! I posted the op amp I am using and will receive on Monday. They have 10MHz unity gain. Your slope is most likely the result of the op amp's frequency limits and perhaps better C values and R values would help. I posted this circuit to my FTP because it is simple and works every time. The OP AMPs coming to me are these:

http://02d1852.netsolhost.com/radiant/NJM2060_E-1.pdf

quote me:
"Mouser part# 513-NJM2060D @ $0.63 63 cents each in singles, minimum order = 1 piece. I just ordered 27 because shipping cost more than the parts. I pay $0.53 each (break at 25 pcs). Can't wait to get them !"

I built an 8-bit, binary weighted capacitor array so I can vary the frequency of the circuit by changing C in 255, 1/255 steps. It helped to handle an inherent offset issue with this simple circuit.

Thank you for building it. Your video is very helpful,

Greg

[sucahyo]

TPU work better with sine wave input than pulse input, but pulse input provide safer operation and easier to do, I forget the source, sorry.

I don't know how many turns really needed. Should be easy to wind neons in series maybe pulsed by stingo coil to this coil maybe use straight on stingo with no neons.

Filling up toroid with a coil usually work. There is no use for secondary right now, so you don't have to wound secondary.

It just occurred to me that having the regular stingo potentiometer feedback from the end of the coil to the base of the PNP may help the impulse shut off faster. If it doesn't destroy the op amp.

The chance for that is very high so make sure to use op amp with high voltage rating. anything with the spec of 555 will die easily.


BTW, I got dimmer neon with bifilar. bifilar produce same brightness as series, both half of stingo withonly one filar used.

[Farmhand]

Wow some very interesting things being done, that Captret thing looks awesome, I don't know how i missed that thread, excelent stuff.

I feel like i'm being left behind in a cloud of dust.

I'm still not sure I understand Stingo yet sucayho your mind works in mysterious ways, he's got me baffled. I think I might just try tinker with my Bedini SS to reduce the duty cycle.


Cheers

Aha found some trim pots they might do, back to Stingo .

commercial toroids

Quick question:

How far short of the mark do commercial toroid transformers fall? I mean I was looking at several and most are fairly universal because of the multiple windings they have for configuring them i.e., e.g. parallel or series, etc.

I was just curious if one was, at all, worth the investment.

Thanks in advance,

Greg

Thanks 7mix for your info, and suggestions too
Today i worked on stingo-bedini configuration, so i postponed this impulser
project for one day, but tomorrow we are going to come back to our impulser
If you are in the mood to amuse yourself with what i did today instead of
playing with impulser, here it is :

Hi Greg, what is heck a binary weighted capacitor array ?
I cant wait too you to get them (OP AMPs)

Hi Greg, what is heck a binary weighted capacitor array ?
I cant wait too you to get them (OP AMPs)

A binary weighted 'thingy' is usually based on the binary counting system like computers. A binary weighted resistor could be a DIP-8 switch or 8 switches hooked up to some resistors so that if you flip switch 1 you might get a 1ohm resistance. When you flip switch 2 (sw 1 off), you get a 2ohm resistance, switch 3 (sw 1, 2 off) is 4ohm resistance, switch 4 (sw 1,2,3 off) is 8ohm ... doubling for every switch and so on. If you have 8 switches that's 1, 2, 4, 8, 16, 32, 64, 128. If you turn them all on you would have 256ohms, but also, 1, 2, 3, 4, 5, 6 ... all the way up, 253, 254, 255, 256ohms, just by flipping the switches in combination. Its allot more SOLID than a potentiometer ... and repeatable. You can do the same with capacitors, and end up with a variable capacitor that has a very wide range indeed. These are the two devices I make and use so I can get repeatability with my test circuits.

Greg, can you translate me to english this sentence :

Sorry ! "how something falls" or "where something falls" is informal english for asking if something is "any good" (when compared to other similar things) ... or "where or how does it stacks up" is another expression or a way of saying "what is its standing or ranking" when compared to other similar things. Many english expressions are often only 'parts' of a complete thought and often it must be taken in context with some known situation. Two people might be talking about how often things are thrown away carelessly. On person might say "...you know what they say ..." and no one says any more because each knows what the other means because they both know the phrase "waste not want not". These are probably bad examples, but I know without the culture-part, the language-part is hard.

So, you make it , you do not buy it as finished product ?
If so, than teach me how to do that...But only if it would not be
annoying/bothering to you !!! It means, if you can illustrate this
procedure with one picture or one or two sentences ok, but if it
takes much explanations dont bother yourself with it, because we
have in this thread much more important things to do, dont we ?

Thanks Greg for your teaching, but thanks even more for making me laugh,
i must put this smilie , that is how i looked like when i have read for
the first time above paragraph because i thought i was going to understand
nothing again...Maybe the best reason for this thought was this :
"waste not want not"what a heck does it mean again
But the main part of making me laugh is this : You spend a lot of words to
explain me the verb or phrase or what ever it is how far do toroids fall
but even harder part of that sentence you did not explain to me, and that
is syntagma short of the mark which was the main reason of my
confusion
I remember how one american-english writer once said something like this :
English is the one of the easiest language to speak it bad , but in the same
time english is one of the hardest language to speak it well/good...Is that
right ? And when we add culture-part too to whole this language stuff where
we are ? Probably where all this misunderstandigs began in the first place :
Tower of Babel...Fortunately we do not have to communicate in french
