Joule Thief

[NickZ]

  I'm glad to hear that you can take it... My current joule ringer set up has over a 1000 volts going through it, and when I touch it,  anything in my hands goes flying across the room, as I jump out of my seat.  The ferrite rod cores are the worst, there is nothing "cold" about it, you can probably burn your name in wood with the output, like WoopyJump has shown.  In any case, I always feel invigorated afterwards.

Because it is cold electricity
from the secondary and the
primary uses hot electricity.
There is very little current
from the secondary . You
need Current more so than voltage for a Tesla input . I
guess you can try and reduce
the Voltage down with a
transformer of some sorts to
12 volts and see if that
increases your current enough to power up a Tesla supply .

Thats not what i meant. If the primary coil of a tesla coil could somehow get a cold electricity, it will oscillate on itself because the cold electricity supply additional energy to the coil and prevent it from stopping. This will eliminate the need of complex oscillator circuit to maintain oscillation in the primary coil and the need of feedback from the secondary for energy supply in the primary. So instead of building efficient oscillator circuit, we must discover how to make the primary self oscillate with help of cold electricity. I know theres a way but we must discover it.

Well, it would sure be nice if you turn out to be right. I'd like to know how to make that kind of cold electricity, though. If you have any ideas please let me know.


Shocking!! Yep, dittoes on the smell of burning meat and the flopping around. Always keep one hand in your pocket around real HV!
The sstc I showed in the earlier video almost cost me a finger. I'm quite familiar with taking the "cold" discharge of a properly operating TC onto a wrench held in hand, without any sensation at all. But for some reason I reached out and tried to move the setup by touching it with the side of my index finger, just above where the primary is. Not even anywhere near the top! And I got a RF burn from that that penetrated nearly to the bone and took weeks to heal. It was like someone had stuck a red-hot soldering iron into my finger only worse. The weird part is that at first it didn't hurt and looked like a pinprick. But the flesh was instantly cooked throughout a volume about the size of a large pea, and once my body realized this, oh boy. If it had gone a bit deeper actually to the bone I don't know what might have happened to the finger.
Fully healed, though... it's hard even to find the scar now.
I made a static machine, the Dirod, that charges to a voltage depending on how many turns you turn the crank. It has a 400 pF capacitor stack on it, and when it's charged to 50 kV it delivers a very startling but hopefully not dangerous shock. Without the cap stack in the circuit it is much less aggressive, and we used to give it a few turns and deliberately take the shock from that, as a little pick-me-up, like a shot of espresso.

The secret of the Joule Thief is revealed in the oscilloscope analysis file nov12.xls and the full pdf explanation.

The pulse switching induces a high voltage BACK EMF that leads-out electron motion energy.

The particular configuration showed HARD evidence of Output Power > Input Power with COP around 50.

I took the trouble of downloading your spreadsheet file. Here's the image from that file.

LTseung is scoping directly across a battery, not hooked up to anything .... and is obtaining a SINE WAVE with a stated "peak to peak" value of 1.44 V.
Then he hooks the battery to the circuit and scopes across the battery and gets another much smaller signal that his scope is telling him is 220 mV "peak to peak".

The Question of Input Voltage? Boy, I'll say.

I want to know this: How do you measure a DC voltage source... a BATTERY.... and obtain a sine wave output, with a value of 1.44 volts PEAK TO PEAK ?

Is it possible, LTseung, that you have made some kind of..... ERROR ??
