Hi jim
nope thats Jiffycoil secret laboratory lol
Everything has its place quote from Jiffy wow

I've never seen such a clean and concise working environment as Jiffy has. I mean, I just couldn't imagine having everything to hand, knowing where everything is and being able to readily pick up the exact tool needed for a job lol. His work area even has a framed pic of Tesla on the wall...i'd misplace even that !

Great demo of the 'quack set' Jim. Brilliant to see a reuse of equipment that's 3/4 of a century old !!!

Totoalas, bifilar pancakes, hmmm, maybe that's where i'm going wrong. I have a vid on YouTube where I have a phone charging using a single wound pancake and all of that is fine with LED's and other gear. But, there has been zero motor power from a pancake so far and it's perplexing
The tested phone charges at a comparable rate to the wall adapter, which means a good amount of power is being enabled, yet motors are flat dead

Tickle those airwaves Scott

I am tempted to tickle them with another coil with an audio signal running though it

Thing is, I bet we've all done exactly the same when messing with these fields !

That is a good thing.All this open work with good documentation makes it much easier.

Great vid, it really showed how the effects could change.

Thanks. I should have something novel for you soon

Cheers

Looking forward to the audio experiments
I do hope my comments were received correctly..I just meant that moving our hands around the energy field in such ways is a lot of fun.

Found another good transistor for the lower voltages !
The D471, or to give it the full name, 2SD471.
Datasheet here: http://www.cbtricks.com/radios/galax...pdf/2sd471.pdf
This one came from a cheap brand boombox and has been sitting in a storage drawer for years. I wired it up to a 'Walgreen' tower, just to see if it would run and was very impressed indeed. Plasma is the strongest yet, audibly buzzing and hissing using the Nokia phone charger and all traits are perhaps superior to even the best so far otherwise, the C3198 !
It has an available output of 1W, much better than the common 150mA or so of other small transistors.
An audio frequency amplifier, the D471 ought to be found on mid 1990's radios and hi-fi's.
This one is marked 'L', which is a mid range example.
The vid also shows a dipole receiving idea for a neon, which increases the field reception well. Dipole wire gauge is the same as the bell wire used for the primary 2 turn coil (if you're familiar with ventriloquist Jeff Dunham, it's a neon light......on a stick)

@ Slider2732

I have replicated your pill bottle tower using 2N2219 transistor. It lights neons and fluorescent tubes but no plasma so far. I will post more info if I get it working better.

[Slider2732]

Cool, do you have a pic by any chance ?

Looking at the 2N2219 datasheet ( 2N2219 pdf, 2N2219 description, 2N2219 datasheets, 2N2219 view ::: ALLDATASHEET ::: )
I note the saturation voltages are comparatively high and the DC current gain to be quite low at 75. Max output is good, at 800mA though and they are very very quick switchers !
It would seem, from my experiments, that low saturation voltages ( around 0.3V), high output current (1A) and a good current gain (around 200) work strongest at around 5V 300mA from wall adapters. The general concensus seems to be that my trusty old Nokia charger is probably putting out that sort of voltage rather than 3.7V
Also, the strongest performers get mildly warm after a few seconds and will become greater than hand hot after 1 minute. A heatsink of pretty much any type will sort that out. Super glue can be used to attach transistors that don't have screw mount holes, at a pinch. Much safer to wrap a piece of bent soft metal around it with pliers. I generally spin one up without a heatsink and note the temperatures, then fit a heatsink to suit.
I'm no expert at all though.

That d471 is amazing. That's a massive field and strength you're getting from such a small tower. Is that plasma arcing to something or is it just spittng out the end? Think I need to research these transistors more. Thanks!

[jimboot]

@slider I hooked up an av plug to my multimeter probes and got some readings. Close to my coil i was getting 165v. Wondering if you've measured the walmart tower? Its prolly already been done by others but the readings seemed to match the field strength demonstrated by the LEDs

Your output is increasing by each post lol
I used terminal block to cool off mpsa06 plus tranny mod with 12v dc supply
Unfortunately the longer the operation the transistor popped and cracked
Youre right maybe set my goal back to 5 v dc for this kind of transistors
will start collecting the Nokia chargers

cheers

Thanks xee2, that's the same circuit as I use, with just 3K as the resistor. Every transistor is different though.
3.1MHz eh, that'll be a good approximation for the frequency of any Walgreen system ?
Heck though, I believe I need to be at around 6Hz for Tesla replications ! Time to break out the 555 circuits and see where things go

Yep Jim, just free running plasma into the air
Got 3 DVM's here and none work...I need a DVM to fix them. Got 2 analog volt meters and yet they don't work either !!! So, figures as xee2 posted on his Imageshack circuit pic are really gratefully acknowledged.
Have attached a scope pic (Eico TR-410 s/h from Ebay for $20 uncalibrated). It's of my Wensleydale tower and surprised me with not being a proper sine wave. Else, well, otherwise it's got the same infectious disease as the DVM's lol

Ah totoalas, yes I need the increases for my flight stuff. Kinda the driving force behind all this. It opposes much of what was thought would be needed, by going smaller and smaller and using less and less power to gain equivalent results. The final flight system is to fit in a standard R/C transmitter case. The first version may have a jack plug on the side to plug an external lift tower/mat into, for take off's. That's where Slayer/Jonnydavro/Lidmotor's wonderful work with chokes may become integral.
Here's something plucked out of the ether which i'm pondering on - what's a resonant 'Darlington' choke ? lol. The mental flash image is of 2 chokes, the output of one feeds the second, like connecting transistors. But, both are in unison, resonating and ramping as they produce the power. The energy resonance of the second also feeds the first, yet draws no extra power from the circuit in doing so.

Actually several MHz works better for wireless because more power will go through a small capacitance. But,lower frequencies work better for ground conductance.

@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.

That seems a fair enough amount of field energy xee2, the major differences are normally within the transistors and then the primary coil placement..maybe the smaller the tower the more finicky. Strange effects have been noted in my own tests, where one will work best with the primary at the base of a coil, another with it part way up and some only giving plasma when the primary is right at the top. All is a Goldilocks situation eh

Interesting video Jim. Always useful to have real world figures and an important step when extending the range. Loss figures from 1 wire transmission springs to mind, for selecting the best gauges to use.
About the scope - I don't connect the leads anywhere ! They can sit a foot or so away from a tower and the waveform is seen. I saw a vid a short while back (forgotten who posted it unfortunately) where he said scopes may be damaged if directly connected to HV. If the probes are close to the tower then the waveform can be too large for the screen, if say 3ft away then too small. About a foot away, just placed together is how I use mine.

@ Slider2732

Do you know what size wire you are using for L1 coil?

I tried several transistors with higher current gain. The following worked but did not produce plasma. All are plastic and thus hard to heat sink.

MPSA6515
TIS92B
TIS97

It seems that the plasma secret is in the L2 coil design.
