9130 P-channel Power Mosfet

Hi cikljamas, you can pulse the low voltage winding on a normal transformer.
But you won't get any Kv out. probably only what the usual input rating is.

Gmeast,that is the diode i'm talking about the 1n4007 diode in cikljamas' drawing there(last post). Do I need one of those ? Is that important? It seems important. Do you have a diode there ?

By the way I think 15Kz is dodgy, I think i just accidentally tazered myself but only with 220v at 15Kz, might be a good idea to try to stay away from 15Kz. I took one end of the sine wave in each hand, it felt really wierd. But i'm ok now, I think. I would've been a lot more carefull if it was low frequency. I didn't think it would do that at that high of a frequency.

Anyway I put that away and i'm back on project.

Cheers

That is not similar to the circuit we are working on because the Fet in the drawing is a P-Channnel FET. That diode is protection for the FET. In our project, the coil is connected to Battery+ and we 'ground' the other end with our N-Channel FET. Most of the FETs we're using have that protection diode built in. In the case of cikljamas's drawing (from PJK Book July 2010) you would ADD a Recovery Diode going from the the coil/FET node to battery-.

If you look at the schematic for some of the Mosfet we have been using you will see the protection diode in the Mosfet symbol. Most Mosfets whose part number starts with a "9" are P-Channel Mosfets.

What is the transformer designed to do ?
Measure the resistance of the windings and use the one with the least resistance, and see what happens.
Be carefull.
Is it a step up transformer, center tapped or something ?

Hard to say.

cikljamas, I built that 555 circuit a while back, look in my YouTube account. I wouldn't recommend it, the 555 is not nearly fast enough and does not have fast enough switching times. It may be possible to find a better performing 555 but I don't think it is worth it. I have that 555 circuit built on a board somewhere, if I find it I will shoot some video with it.

Without a scope or at least a dmm that can measure high frequency impulses, there's not much point in building impulsing circuits. The slope of the impulses and the duration of the impulses are at least as important as the frequency, if not more. Save your pennies and get a scope. You might want to look into making a sound card scope. Although they can't sample faster than 44khz and probably won't take very many volts without dying at least it would be useful for measuring the trigger waveforms.

Could you tell me what do you think about this :

Could we make this easier than project that we are working on since it
is already finished project and its purpose is the same as Watkykjy stuff,
selfcharging, selfsustainable device, and there is no microcontrollers too,
in fact it is very old stuff (Tesla), and we still want to reach China across
New Zealand instead of across Pacific ?

7imix,

That's very good advice to cikljamas. I recommended that a scope should be his first priority. I know you can buy a PC Scope for $175 US and that might include shipping. I had to sell my $1200 digital scope when the economy bit my ass, but I got a PC scope (USB2 interface) and that's what I'm using now. It uses your PC's other features like image processing, file stuff, etc., so that's a good way to go if you don't want the risk of a crappy, glitchy used scope or a scope from Eeek!Bay.

7imix, did you like my new scope captures?

my toroid

Well If I would read the Toroid Winding .pdf document carefully, I would have picked up on the line that said:
"So no yellow tape as below to start winding your coil. We should just 86 this photo ... "

And it shows the toroid core wrapped up in yellow 1P802 transformer tape. To be honest, the core is a much nicer surface to wind onto.

This means I don't need to wait for any tape .... HOORAY! ... so I start wrapping tonight ...PHEW! So Glad. I guess if I do a really professional job of it I could call myself a 'Wrap Artist' ... oh booooooo ... Sorry guys.

BTW ... I am building something that will be faster, crisper and less of a headache than a micro. You won't need to know nothin' except that your gate driver circuit is built right ... it's going to be sweet. Frequencies from 500Hz to 100kHz & Pulse Widths from 0.003usec to 2msec. More on the evening NEWS.

Yes, it would be great to build the don smith device, but it's still worth working on the toroid project. You will probably want to have a scope AND a high voltage probe to tune the don smith device... So it's not going to be any cheaper than the toroid anyway...

I'm pretty sure the toroid device operates in a very similar manner to the don smith device. In the don smith device a spark gap/capacitor/primary coil combo sends extremely rich harmonics into the secondary at high frequency. The toroid produces rich harmonics directly by pinging the different coils at different times. The don smith device taps the high voltage, high frequency with extremely fast diodes in a bridge rectifier, smoothing capacitor, voltage divider, 60hz oscillator and step-down transformer. I'm not exactly sure how the toroid recovery works... Since it is self charging and not trying to run other devices it seems that the recovery diode and choke are enough.

[7imix]

Gmeast, your latest scope captures look great. Looking forward to being able to produce waveforms like that. Great oscillations, and it looks like the diode is doing a good job. I want an air core coil with a lot more wire on it. I am working on it. Just using a spool is a good idea. I also need one of the diodes you are using, I just have basic diodes like the 1n4007.

[Farmhand]

Hi all, I got these fast recovery diodes, FR302 for recovery and FR307 (not for this) to make FWBR's they were fairly cheap, they can rectify three amps.

FR302 pdf, FR302 description, FR302 datasheets, FR302 view ::: ALLDATASHEET :::

Last night I made some input leads the same length as the coil I was using, but not much happened, I guess it might be better to try to make only the positive lead resonate. My nano scope must be getting close i've been waiting for four weeks now. That will clear the fog for me a bit, I hope.

I just have to track down some transformer tape now.

Cheers

I thought I was using a 1N5408 ... that's a 1000V reverse rating, but I'm actually using a 1N5404 ... a 400V reverse rating. They are both from the same family and are categorized as 'General Purpose Rectifiers'. They are typical 3A rectifiers, 200A non-repetitive surge and fairly OK thermal characteristics. I didn't realize their forward Voltage drop is 1.2V, so that unfortunately isolates a fair amount of energy (into a 'dead zone') that can never be recovered ... boo hoo. crackahcrackah (where'd he go anyway?) proposes to do what Tesla showed in one of his patents (568,176), and that is to put the oscillations DIRECTLY to work via a tuned LC network (NO recovery diode) and thus avoiding the 'dead zone'.

There are much faster and better rated rectifiers available but I don't have any, don't know which ones would be best for our efforts, and besides, I had these laying around.

[Farmhand]

I'll have a look at that patent, I think Crackah was banned.

I usually use 1n5408's too. Maybe it makes a difference not important for now though really. Mine are still in the packet. I'm using 1N5822's at the moment they don't seem to get as warm as 5408's. I know 1N4007's don't like much current, they get cooked easy.

I tried a pair of "shunt" capacitors on the induced winding of the little torroid, it was strange because I got 220v unloaded and 3.8v loaded with a 240v 60watt light bulb, the bulb was glowing a little bit, and at the same time 20v DC from the FWBR across the coil side of the caps. It was then I tazered myself when I open opened the 220v. So it got a bit blurry from then on. Anyway the shunt caps don't affect the frequency, the current draw go's up when the induced winding is loaded. Looked like normal behavior, except for the 20VDC across the 3.8VAC. Maybe thats normal too I don't know.

The caps are small non polarised one's connected in series with the windings and loaded at the other end, kind of thing. I think using them like this is called "shunt capacitors" i'll edit a pic of the pair of caps setup shortly.
I can't find that darn drawing either can't get back there either.

I want to try locking the output frequency somehow, but how ?

Cheers

Caps, I connected AC load to base caps where FWBR is connected and measured DCV on the DC of the Bridge while the AC was loaded.

This looks interesting-

OS:Tesla transformer - PESWiki

From PESWIKI

Factional distillation of current
The manifestation of discharge current / coupled current is the first stage of the process, accumulated in a capacitor, in advanced configurations, Tesla then performed factional distillation of this coupled form of current. This is not in Tesla's patents, so is not part of the main article, but appears from other sources of information, i.e. Gerry Vassilatos Secrets of Cold War Technology: Project HAARP and Beyond, to have been the development path Tesla took, and is in all probability, the much rumoured free energy secret said to have been held by Tesla. I have created OS:Tesla transformer for OS collaboration, to try and validate the methods by which I believe Tesla distilled discharge current.

[Farmhand]

Tesla's way.

Looks like crackah was right.

It appears as though this is a desciption of his way of doing this.

Almost looks like the circuit I had going last night. Oh wow. The two choking coils are there on the input leads and all. My cap across the break is only 470 uf. Maybe it should be bigger or smaller.

I must study this. These patent documents have so many unecessary words, it make's them hard to read.

Thank you so much Gmeast. That is the desulfator circuit. But without diode recovery. As far as I can tell.

Tesla was a tricky guy thats for sure. Spin a few things around, who needs MOSFETS and Micro's.

Cheers

P.S. Did I mention that it looks as if Seamonkey also managed to get banned. What a pity. I would like to track him down to ask him some questions. I have a feeling Seamonkey was not just a banana eating sailor. It seems we just don't know who it is we are talking too, which is interesting to think about. I guess it really doesn't matter.
Best Regards Seamonkey

You know what ! Now I see that Don Smiths Device that cikljamas wants to replicate is actually a Solid State Tesla Coil with an internal central primary and rectified output, Oh My Goodness I have to have one of those. Moving the primary in and out of the coil changes the Volts x Amps ratio. It's in the Research and Writings of Nicola Tesla, and Don shows that drawing in the video, it just didn't click to me.

Diabolical. Just number up on the secondaries with seperate rectifiers, without affecting the input. Maybe ? .

cikljamas really know's a good thing when he see's it.

Rgds

Ok, so here is the circuit I used last night, I don't have toroidal chokes and a square transformer I have air core choke's and a toroidal transformer, and I have a recovery output directly from the primary negative. But basically the same, the 470 uf cap on the end of the board is across the switch. Wow.

Am I seeing that right ? I just need a HV transformer. Maybe.

[Farmhand]

Interesting development

This is from the Patent 568,176.

It appears to me by this drawing that this is Nikola's Version. Obviously it works.

This is the input current and recovery waveform while charging a second battery with the secondary output unloaded. Output shot would show a + - 300v sinewave.

The bulb only glows a bit and the input current rises to about 2.25 amperes.
But the second battery keeps charging and the AC sinewave shrinks down to represent 3.8VAC, but the DC from across the bridge over the 3.8VAC is 20v. THe meter must be reading it wrong.

I think i can safely say that my transformer is not up to the job, but it is interesting to say the least.

Hi everyone,

I've asked this before, and now I will again. Given the nature of the technologically developing industrial society of Tesla's time, there DID NOT yet exist the 'Big, Bad, Electrical Power Generation and Distribution Ogre' that was dead set on controlling 'us' ... the pitifully dependent consumer. Most folks of the day were thrilled at the electrification of their communities, industries, cities, and all. There was not YET the motivation to decentralize power generation and distribution. Of course the likes of Westinghouse and other industrialists wanted to put 'meters' on everything.

Phew ... ! Now the question:

Where does Tesla EVER say "... here, make this device this way and you may have self-generated electrical power, controlled by you, produced by the environment and you will never answer to the utility company again ..."

Has he ever said something to the effect that his motivation(s) were to provide a means by which the average person can have energy independence ... or is this a product of dreams and wishes fabricated by our perception of what our modern society has become ... that is being subject to institutions and people we don't like very much.

More simply put ... did Tesla EVER (actively, specifically) peddle Free Energy?

If you asked Tesla about 'Free Energy' would he respond "WHAT...ARE YOU NUTS?"

I just don't think what we pursue (here) was (in the least) on Tesla's mind let alone on anyone else's mind OF the time.

All of Tesla's patents and pursuits were big, grandiose, industrial and potentially profitable for him ... such as:
"APPARATUS FOR PRODUCING ELECTRIC CURRENTS OF HIGH FREQUENCY AND POTENTIAL"

I have just never run across anything about Tesla that actually said or hinted at free energy being a goal of any of his research or inventions.

Please show me otherwise. If you can't, then what are we doing here?

This question does not damp my enthusiasm for our present, specific pursuit however.
