HF HV Phenomena Observations

[dR-Green]

Hey Farmhand. That's looking pretty cool Are you deliberately making it spark that slow?

I literally just finished making these



I wasn't going to post anything here because I didn't have anything to show except the fact I've made them, but a test run using a crude primary last night revealed the opposite of what I've noticed with the spirals. With these little coils, smaller capacitance gives a clear higher output voltage, and the significance of that might become clear in a minute. So with that in mind the test run after finishing them just now quickly went from 1860pF of ceramic caps to 200pF vacuum caps. I haven't tried any smaller yet because it revealed an effect that I think is worthy of posting here. So I'll explain the coil specs here, then I'll get to getting some video or pics of it.

I haven't made terminals for the coils yet. What I have in mind is 18mm MDF of a certain diameter using a holesaw, and then spray this with some 99.9% zinc galvanising spray.

Anyway, the specs. 20mm pvc conduit for the secondary, 15.5cm winding length consisting of 28.8 grams of 26 SWG. The primary consists of 28.8g 17 SWG, 12 turns, 42mm diameter. The primary and secondary are wound in the same direction on the coils, but the two coils are wound in opposite directions to each other. But everything is fully dismantleable so the primaries can easily be swapped and I've built them with making/testing different primaries in mind, the basic idea of which can be seen here



28.8g of wire was used because I originally weighed and matched them for the spirals, but as you may remember the 26 SWG was too long to fit on the base. The primary was also weighed before I improved the design of the spirals, so I basically had a complete matching set of wires left over.

So I have no idea of the tuning of it and the resonant frequency or anything. But the primary should be somewhat in tune with the spirals primaries give or take 0.2g of copper so I'll play with that at some point. I'll be back soon hopefully with a video anyway

[edit] Also the big gap at the bottom is so they can be used for Johnny Davro's simple SEC by putting a wire up inside the secondary connecting to the transistor base, so they are supposed to be as versatile as I could think of

[Farmhand]

Hi dR, You're welcome to post here, no probs. Yeah I am deliberately making
pulse slow by maintaining the same input EMF from the transformer while
making the spark gap wider to get bigger discharges firstly to study the
effects and secondly to test out the coils under strain, testing for leaks
.

I just blew through a set of primary caps 5 x 3.3 nF caps in parallel, cooked
em with too wide of a spark gap, I think i found all the leaks and I've
stretched out the discharges to 100 mm now, I've had to use two sets of 5
caps in series for the primary cap. At 75 mm discharges it shows multiple
streamers from the grounded object to the terminal and a single or double
strike back from the terminal to the grounded object. I'll get some more video
and make it short so it uploads quick. The 100 mm streamers look kinda cool.

I'm using a cap bank and tank on the ignition coil as well to do this, if I drive
the ignition coil directly from the transformer and use a small gap it will run
faster and still build up good sparks but not 100 mm without quite a bit of
power, I need an NST or more ignition coils to make it's hair stand on end,
and more circuitry for multiple ignition coils, I'll get there, My goal is to have a
versatile system too.

Those coils of yours are very nice, with the primaries being a tuned length
you will only need a small amount of capacitance for the primary to be
resonant with the secondary with it's toroid and connected to ground or
something. Very cool construction, how far from the secondary is the primary?
Coupling wise I mean, a fair gap helps when increasing the voltage so I found
out, I like the idea of the painted terminals too, I want to try that, the tape is
far too time consuming.

I noticed when tuning mine that connecting the secondary to ground lowered
the resonant frequency quite a lot. My Primaries are not tuned length so I use
capacitance to match the primary to the secondary using the function
generator, which is very handy.

How I build a coil is I imagine what I want the coil to look like for me I like the
three coil design, then I wind the two coils for the secondary and make the
terminal, I then find the resonant frequency with the function generator. Then
i can decide how many primary turns I want and wind that, then I use the
function generator to find the capacitance I need to make the primary
resonant frequency match that of the secondary, then I make the primary
resonant at a bit lower frequency, if the coil is ground connected the
resonant frequency will be lower than if the coil is connected to another coil.

I do it this way because by changing out the primary for one of more or less
turns and changing the primary capacitance to suit I can adjust the input
power and voltage out. The power into the system is limited by the
frequency, the input voltage and the primary capacitor.

ie. if you have a system which operates at 600 Khz and you have only 240 pF
of primary capacitance then you can get into the primary much less power
than a similar system with 10 nF primary cap. Or a system operating at 6 Mhz
with 240 pF will get a lot more throughput than the 600 Khz with 240 pF.

With the frequency fixed at resonance there are two options left for more
power higher input voltage (wider gap) or more primary capacitance with less
turns in the primary, Eric does say only one primary turn is best, a big fat one.

I'll try not to get the camera struck or blow anything else out or up.

I need a HV variable cap for the receiver at least to tune it. Sorry long post,

Cheers

After all that filming, and after going to the trouble of setting the mic up to have sound this time, I had the wrong source selected so there's no sound again Oh well. Also my webcam isn't capable of detecting the effect. Basically the whole wire coming out of the top of the coil has mini lightning bolts coming out all along it. Different spark gap settings determine how far down the wire they go. At a certain setting it looks like the plasma is sort of pulsing in waves going up the wire. Very interesting to look at but the place has never stunk so much of ozone.

All in all I suppose the video isn't really worth looking at especially since there's no sound for any reference to the changes I'm making, but here it is anyway, once its finished processing. When the two coils are used they are connected in parallel. The best view I can get of the wire effect is at around 4:45

Looks like those coils are working well, is the discharge like rope with lots of
individual filaments or is it more flame like ? The second coils output seems to
match the first one fairly well. Hard to see the spikes from the wire with the
youtube video but I know what you mean.

It is mesmerizing to watch the different discharges and think about what is
happening, good work, I can't wait to see them with terminals.

To get the big bangs is hard on the capacitors, as I read Tesla once said when
describing some of his bigger discharges in Colarado, "In order to do so I had to strain my jars to the upmost"
something like that. Sometimes from one spark of the spark gap there can be two discharges, I like to slow things down so I can get a good look.

Also it is very loud, if you did it in the city the police might show up looking for weapons.

Cheers

Hi all here's another video, the neon busted after the first few hit's before I
made the video.

Now I need to make an air cored or oil coil to try replacing the ignition coil with
one that will work at much higher frequencies.

I have some idea's but I'm not sure which way I will go yet.

Cheers

Those big discharges can be pretty scary I think. I didn't have very big capacitance at the time, but it's with big and slow discharges I was getting shocks through the other end of the fluoro. If you watch or read Peter's Free Energy Secrets book/video, or The Secrets Of Cold War Technology, he states that spark duration also affects the kind of effects you get. Some of the effects of the big and relatively long pulses sound very dangerous, including Tesla physically feeling the shocks through glass and copper shields, exploding thin wires etc.

I don't know all the different types of streamers. I would say that with a bigger spark gap it's rope like, and with a smaller gap it becomes more focused at the top/end of the wire and flame like. I've started calling the coil the birthday candle.

The arcs don't quite look the same from both coils in the video because of the angles, but I'm not convinced that they are perfectly matched just yet. There's slightly more lead-out wire at the top of one coil, and more lead-in at the bottom of the other, so my opinion on it at the moment is that the extra length of lead-out wire causes the difference in plasma. I'll know for sure when I make the terminals and cut off the wire I don't need.

I'm very pleased with these vacuum caps though, I can definitely recommend them. They're designed to be high frequency but also their simplicity makes me confident in not destroying them any time soon. They can't blow like a ceramic cap because it's just two metal cylinders inside a glass container. If the voltage gets too high then it should just arc over into the other plate. The only risk is dropping them or getting smashed in the post

As for how far is the primary from the secondary, the secondary is 2cm diameter, and the primary is 4.6cm diameter exactly. (4cm diameter circle with 6mm dowel holes drilled on the 4cm mark, plus the dowel = 4.6cm coil frame). So I'd say 1.3cm distance.

UV protection for the eyes might also be a good idea for this business I'll be back to respond to the rest, thanks I'm interested in this three coil design but have no idea how to go about it. I was thinking keeping it really simple and make a small scale model, and copy the patent exactly using the same number of turns as in the diagram. That approach seems to have worked for Eric Dollard/the spirals

Hello again, I was experimenting again with two Tesla coils having their
primary coils in series oppositely. And I had to stop and admire the beauty of
the streamers, I think I've worked out the manual functions of this DSLR
camera so I hope to get better at using it for time lapse photos.

These pics range from 1.5 to 2 seconds exposure time (shutter speed) and 3.5 to 5 aperture.

Here is the primary circuit I used this time.

I've got some video and will upload and post it in a few hours, enjoy.
It sure is pretty to watch them twirl around and dance in and around each other.

[Farmhand]

OK so the left terminal is + - and the right one is - + the ball is Earth 0.

So we could look at this way the two terminals represent the yin and the yang
and the ball represents the Earth (matter) to form a triangle and completes
the trinity - Chi.

From the alternating potentials of the Aether matter is born.

The yin and the yang love each other but without the Earth 0 they would be
the same and nothing. So there must always be three.

[Farmhand]

Hi all, I made an improvement to my method of power supply and now I can get
a bit more power into the primary caps, so an improvement in constant power.
I'm getting roughly 20 to 30 watts through the setup now, but as soon as I
upgrade some diodes I think I can double that or even tripple I hope.

Anyway here is a short video, towards the end I play around with the four different power levels.

Here are some more pretty lights, it's very difficult to get good photo's of the
moving arcs the video is better.

Lot's of experiments can be done with a variable power Tesla coil. A lot of
effects and things are very difficult to show on film or some even on video.

Well it all certainly looks like it's getting more impressive anyway Have you tried any of the one wire bulb lighting tests and pot of dirt etc with this setup?

[Farmhand]

Hi dR, No I haven't tried any one wire lighting experiments with it. After I've
finished my powering arrangement for the spark gapped setup, I'll do some
more experiments. I refuse to use the wall power though, I have batteries to
easily provide 1 Kw of power and solar panels to charge them as well as other
charging methods. I want to be able to use my setup anytime and for long
periods. ie. overnight.

At the moment I am working on improving my supply circuit and I have made
some improvements with that. Much more to do yet.

Sphere V's Point discharge.wmv - YouTube

All devices of mine after the battery are self built. So I think I'm doing OK.
And learning a lot.

I'll also be spending more time on my two phase AC motor project, I should be able
to use the motor for lots of things including rotary switches. For phasing and
such.

Some people just see arcs, sparks and plasma but I see electrical discharges
to study and learn from.

I watched your video and it looks good, Nice extra coil.

Are your transistors still getting warm ?

Can I ask you what your total power use from the wall is ?

I wouldn't mind betting you could feel the pressure coming off the lights, I can
feel it from the fluros when i hold them near the terminal. I don't think there is
anything special about that, I think it's just HF vibration pressure. I can also
feel the stinging pin prick sensations as well from the disruptive discharges.

I think I solved my transistor heating issues at high power, by using almost
50/50 opposite direction switching on the AC supply transformer the
transients seems to be cancelled and the heat is much less, now a non issue
even over long periods. And the backup batteries are still being charged.

I see some ways to make some major efficiency increases and further improve
my powering circuitry and arrangement.

Cheers

I streamed that video an hour or two ago to watch, got carried away with experiments Transistors are still getting warm but not like before, but I also have a bigger heatsync which also holds the rectifier(s), and a fan to blow the ozone out of my face which is also pointed on one side of the heatsync, so unless something stupid happens then overall it's ok. The setup doesn't seem to want to use over 2 amps now under normal working conditions, any more is a sign of too little base resistance, or the transistor frying, all of which cause a reduced output, so 2 amps is pretty much the max. The minimum is 900mA-1 amp. Due to the spark gap and what not, at this input voltage the minimum with these resistors is 1 amp. When I decrease the resistance the spark gap changes, the bulb gets about twice as bright and the input drops to 900mA. Then there isn't really all that much difference in the light output between 1 and 2 amps. From the wall the transformers on idle are using 30 watts.

Another problem seems to be developing tonight though. The longer I leave it running, the neon starts to come on until it won't go off, if I reduce the gap size then the output gets weaker, it's like the HV spikes are closing in on me Same situation as the tank of water and submarine before

Well done for having built everything btw, very nice work

It's hard to tell about the pressure coming off the incandescent. But I haven't actually touched it because I can feel the heat coming off it, and it's quite hot heat I just made a video of it attracting some aluminium tape though. But I do feel things through fluoros because they happen when I least expect it, I don't like that

Yeah it would be good to run the whole setup completely "free", but like I mentioned before I think, it's a lot easier to get consistency from a mains transformer because of the constant voltage. It's better for me to learn with because there aren't any limits etc. Although now I'm almost within the C20 rate of the battery I was using and unable to use any more so I'm slowly getting closer... Then again that was 12v and now I'm using about 40v. But maybe that multiplier transformer you mentioned could be handy in that case

[Farmhand]

Oh yeah, I'll be working on the PCB layout for the PWM board it'll have two
switches (transistors) mosfet or otherwise on two phases, I hope to have the
first design done on the computer by next week. It should be bullet proof or
transient proof I "hope". I'll need a couple of them for my planned
arrangement.

I want HV at least 1500 volts on four phases at 40 Khz to act like 1500 volts
DC then I can use a resonant charging circuit to double that at HF through
the gap at the resonant frequency of the charging circuit which I will make
the frequency I want to match the secondary .

When I add an inductor to make a resonant charging circuit just before the
primary caps and spark gap the spark gap goes nuts and the terminal voltage
is increased as well of course. I want to try a small bifilar serial connected
pancake coil for a charging inductor, I have a feeling it might be good.

It sure is cool to see the difference it makes, very interesting to think about.

I want to kinda make sure I'm not spending time doing stuff now that I will
make obsolete later. So I need a valid overall plan, well thought out and with
tested principals. I need to test all the individual idea's I have to make sure
they are valid and advantageous. I think I'll use the 0.5 wire I have for the
four converter transformers and get some 0.71 mm or 0.63 mm for future Tesla coils.

Cheers

Yeah good plan I'm starting to get concerned about the number of coils I'm soon going to have because they're already starting to fill other rooms in the house I'd love to get started on a big MT now but there's loads of things I need to find out and understand before that. Personally I think thicker wire makes sense here for overall practical use, unless the plan is to make light show coils.

I'm about to record a video of some interesting incandescent bulb stuff anyway. I think it falls under the HV HF phenomenon category more than MT thread so I'll post it here soon. It looks more like a magic trick or an illusion than reality, reminds me of that line in The Prestige when he's talking about the Tesla character... "This machine was built by a man who could actually do what magicians only pretend to do."
