Joulethief SEC exciter and variants

[Watson]

Well, hold on there. A JT can be built to operate in a resonant state, with the right core and the right amount of parasitic capacitance. The ones I have tuned like to ring in the 400-425kHz range. While your standard JT with whatever toroid, etc. likely will not be tuned to a high Q resonance, its is certainly possible to tune a JT for this behaviour.

Are you sure that the ringing is not caused by the test equipment? A scope probe, for example, has some capacitance, and that may be interacting with the inductance. It may help to put a resistance in series with the probe to damp the ringing.

My Supercharged JT (Watson's eBlog) seems to have a point where it is broadly tuned. Typically it likes to have a capacitor in the 560 pF to 1 nF range. The frequency is typically three or four times that of a conventional JT.

@xee2 nice vid. The field I get from that transistor is not dissimilar.

@slider where have you hooked up the probe for the scope shot? Everytime I hook mine up it kils the oscillations.

I attatched an AV plug to my probes on my multimeter. Not sure how "real" the 180Volts it says it's giving off is but it seems to reflect where the cfls light up etc.
I'm using a c2331 that was liberated from a Humax sat receiver.

Well, the problem may be that the AV plug is made with 1N4148 diodes. These are good for a maximum of 75 volts, some go as high as 100 volts. So say you used two 1N4148 diodes to make the half wave voltage doubler (AKA AV plug), and the two diodes have about 180 volts breakdown voltage total. So when the rectified voltage gets up to 180volts, one or both of the diodes break down, and limit the maximum output to 180 volts.

So you could play games with the 1N4148s and put two in series instead of one. That should double the breakdown voltage. But it also doubles the forward voltage drop and there will be more loss. You could get some higher breakdown diodes such as the BAV21 (200V IIRC) or get some UF4007 rectifiers. The 1N4007 rectifiers have poor reverse recovery time and are very lossy at frequencies above powerline frequencies. They may be 1000 volts and common as dog doo-doo, but they are not recommended for this situation.

If you put two 1N4148s in series, the voltage may climb up to 300 to 400 volts, and then the breakdown could again become a problem.

Another power supply for Slayer ckt

This one can be loop back to the source battery and spply te Slayer circuit
but Lidmotor's Muller replication is getting better

Quick video from me.
I've never seen this done before and didn't realise until uploading it. Not trying to 'big it up', the audio is low volume as is common for plasma speakers, but...
This one is after wondering about using the plasma that can be sent from wire to tower, rather than the other way around.
Would it work for audio ?

@twinbeard
Is that why some have a high pitched whine sound that can be tuned with a variable pot ?
The high pitched sound appears to be directly relevant to output...LED's increasing or decreasing in brightness with the pitch changes.
At 41 years old i'm just glad I can still hear such things

A decent track was selected on YouTube (SL2 - On a Ragga Tip) and experiments began.
It was found that the toroid that's been sat on the top recently, works well to adjust tone and give (minimal) bass and spacial response.
No soldered connections are needed with toroid pieces above the tower and so I show pieces being taken away and the plasma still working. Maybe of interest when looking at the tiny toroid that sits away from the tower and at 90 degrees.
Then, a piece of plastic type mirror is placed on the top and the plasma works through that.
Finally, the wire is swapped for another and all still runs. It's kinda different

What?!?

There is no tuned circuit in a JT, therefore there is no resonance. The rest of this... Is this gibberish for real?

@Jim..
Chris Carson is no slouch with such matters either is he I'd seen the first part to that series, but not the others...the sidebar link videos get a bit appealing when we first start out eh lol. Thanks to your linking i've now watched the rest and can see the importance of Eric and his work.
Longitudinal was well explained by the pipe, readdressing thoughts of an LED that seems to 'lose range' illuminating again at some distant point, when the wave is re-encountered. But if the wave is not a traditional sine type wave and in fact a longitudinal cord, then the frequency of reception of it is way out in every experiment i've ever conducted !
The 12V to 24V car system was good...parallel charge, series discharge. That sort of thing warrants experiments within the primary coil sections of our systems ?
Great pictures above btw !

[Watson]

Looks like a jule theif. Jule theif has two wires three ends, and resonates at a very high frequency around a common iron ferrite toroid core. JLN's toroid is single wraped and pulsed at a mere 200 hz, close to the natural oscillating frequency of magnatisem around a special soft ferro magnetic toroid core. Power is generated from a propagated magnetic field flip in the nanocrystaline toroid. Even though close in appearance, it has nothing at all in common with jule thief.

This next one is a 6v lamp with wireless plasma

[jimboot]

Doing this on an iPad so sorry for multiple posts. I've been watching and reading a lot of eric dollards work. Wow. Don't understand it but am getting an intuitive understanding on it. Here are some pix. Running at 7.5v 220ma below is a xenon tube with wireless plasma

[Slider2732]

Cheers xee2...I think a large part of this may be that i've wound bunches of micro aircraft coils in the past and so can readily 'knock one out' where other folks may suffer frustrations. 6 or so hours to wind a 'Windsor' is quite ridiculous isn't it lol
The toroid is from some random junkbox circuit board from a while ago, when I was looking at Joule Thief's and purely magnetic induction based wireless circuits. It sits near enough just as it came off the circuit board and the idea had been to rewind it. Any toroid will do...if I solder one to another sat on top and then another on top of that, the plasma will still work from the Space Shuttle or a wire. Range is reduced for wireless plasma by about 25% like that, but the whole thing would now be sat an inch or so higher off the top of the tower.

I found another section of similar wire to the previous video and wound an exact same coil, in the same direction too. Then put one upside down inside the other in the Bashar/Russell manner. See morpher44's recent work with the Bashar antenna...cos that's what I did lol. Fascinating in it's own right.
The bottom coil was left as it was in the previous video, the new coil was wired oppositely, Collector to the outer of the coil, Base to the inner.
Fired it up.
It works !
That's a huge amount of metal inside the tower now at least, surprising enough, but the fact that this is all so very crude at the moment raises thoughts on refinement
5th dimension plasma portal coming up hehe
An unfortunately rubbish pic is attached, but hopefully the video shows it better and does show the concept running:

adapter.
This video was the shock result and leading to refinement thoughts of a raised coiled inner Primary
(it also features a paper Space Shuttle, with piece of wire behind, that emits plasma toward the tower !)

Your results are amazing. I am still waiting for #38 wire to arrive. What is toroid on top?

On my 2x3" Walgreen pill bottle, the L2 works equally well with 1, 2, or 3 turns and the turns can be almost anywhere around L1.

[Slider2732]

It's just a piece of thin wire Jim
The breakout point at the top of a tower is normally where we see plasma, so, if we deny the breakout point then a sharp end approaching the tower will form what could be termed a breakout point running the other way. That's why the toroid is on the top. It's soldered to the L1 output with a thick solder joint to also deny breakout at the join.
It seemed a fun idea...but may have practical uses too, with a launch tower being the Tesla tower and some scenery - to commemorate the last Space Shuttle flight as a desktop toy type of display. Nano sized missile models on what looks like a plinth also appeals.

The twirl and pull L2 kinda reminds me of the Bashar thread and the Walter Russell energy coil designs...at least I can think they do something similar and then hide them out of the way under a tower lol

[jimboot]

Nice. What is behind the space shuttle? I'm finding i need to be at 250ma to get plasma regardless of tranny. Using a 1818 pnp ATM. Simply reversed polarity of voltage and l2. Still just using only a tranny in the circuit no other components and starting it with an av plug.

The coil arrangements make one wonder a bit in that device


Coil arrangements featured for my latest 'thing' test.
A scrap of thick insulated copper wire, from a small transformer.
It was messed up and bent up and so was just coiled and tried to see what it would do as a Primary coil, inside the Windsor tower.
Transistor was an A1020 PNP at 7.5V from the 3V-12V adjustable wall adapter.
This video was the shock result and leading to refinement thoughts of a raised coiled inner Primary
