I wouldn't pay too much attention to MileHigh.. He is only a distractor and usually give litmus tests to befuddle and never answers anyones requests to answer questions posed to him. Just go to his profile and check his posts.. You will see what his methods are and they are proven by those massive posts. He is a distractor meant to frustrate anyone trying to do any outside of the box thinking. Why because he has an ego the size of Russia and just as filled with gas... Some of it pointless gas.. Just ignore him like I and many others do. He is a self appointed police for this community driven by his many many years of in the box thinking. Only doing what he was told and paid to do, never going outside of that little world and never having an original thought in his whole life.


Take this for what you will he doesn't mater one bit but to the others who "police" this forum. You got to ask yourself who is paying him now?

You are a classic glazed-eyed forum-paranoid guy with no understanding of electronics.  I am just explaining the simple truth behind a simple circuit to help someone.

What you are basically saying to Sm0ky2 is "Don't learn the truth about this simple circuit, drink my Kool-Aid instead."

You should be ashamed of yourself and at the same time it is very sad.

MH has helped me, and many others, understand basic electronics 101...for free....no invoice or credit card needed.

I, for one, really appreciate that.

Bear in mind the Steven Mark devices ran on a single capacitor, charged only once to start the device.
and it operated the transistor for weeks, sometimes months before the power dissipated.

There went what little credibility you had left, out the window.

As for the rest of your statements about JTs and resonance etc ... I refute thee thusly:

[sm0ky2]

The JT transformer is not even being excited with a continuous signal.  It sees a voltage source across its terminals when the transistor is on and then it sees nothing, no excitation, when the transistor is off.

When you get the timing right, as soon as the transistor cuts off - the field collapse induces a current in the opposite direction, and just as that stops, a pulse comes from the transistor again.

I will use "inductor" instead of "transformer" for the discussion below.

Transistor on:  The inductor is being energized.  Current flow through the inductor starts at zero and starts to increase linearly.  During this phase battery energy is being stored in the inductor and the LED is off.

Transistor switches off:  Now you have a circuit like this:   Battery -> inductor -> LED.    Here the inductor "looks like another battery in series" but that's a simple easy-to-grasp way of stating it.  To be more accurate the inductor acts like a discharging current source with a finite amount of energy.   The real circuit is this:   Battery -> current source -> LED.

The battery and the inductor current source will discharge into the LED until the inductor runs out of energy.  Because it's a current source, you can just as easily discharge into 20 LEDs.  When there are 20 LEDs instead of one LED, the inductor will discharge more quickly.

That's the basic cycle for a Joule Thief.  It has nothing to do with the self-resonance of the inductor.  Since the stimulation for the inductor is <voltage clamp> <nothing> <voltage clamp> <nothing>  there is no real mechanism for self-resonance.

In Resonance::

I will use "transformer", because it is center-tapped bifilar inductor, which makes it a "transformer"...
[The signal through the transformer is no longer a function of pulsed DC, but rather an A/C waveform, of energization and field collapse in rhythmic pattern, as visible on the scope. the energy from the battery is being converted to a higher voltage and the current changes over time, until the LED turns on. Since the resonant frequency is (100Khz-xMhz) faster than the response time of the diode, the LED does not turn off.]

Flip Switch:
Current flows through base and voltage is stepped up until it reaches cut-on potential::

Transistor on: the Inductor is being energized - current flow is not linear, but a function of COS, change in voltage over time is a function of the inductance times the time-variant current flow. In resonance, this is not linear either. Voltage increases until the LED turns ON.


Transistor switches off:  Current reverses direction through the inductor as the magnetic field collapses. The other half of the sinewave presents itself across the coils, since there is a diode, it only exits out the secondary.  Which makes a connection to both the battery and the base resistor. The induced voltage, and the time-variant current flows through the resistor until it reaches cut-on potential and the transistor turns on again. The LED has not yet stopped emitting photons.

By the time the inductor runs out of energy, the transistor is on again, recharging it. <- if not, the system is NOT in resonance.

Transistor On Again: remaining voltage flowing from secondary coil + battery recharges inductor, and the cycle repeats itself. Adding to the voltage each time, until it reaches system maximum.

a bunch of LEDs will discharge it more quickly, but also take longer to charge the inductor. and the voltage drop across each diode affects the total voltage over time induced in the coils.
You will notice each diode you add, they all (except maybe the first one, depending on the type of transistor you use) will get dimmer and dimmer, until no more of them light up at all. Your circuit may handle 10, 20, maybe 40, but eventually you will reach its' potential.

The mechanism for resonance is not "real", its simulated, by the switching of the transistor in place of where a capacitor would be in a resonant LRC. The inductor doesn't know the difference.

A Joule Thief is nothing more than a mechanism for energizing an inductor and discharging that inductor through an LED.   You could do exactly the same thing with a 555 timer output controlling the switching of the transistor via the base input.

Pulse-type switching and discharging are not the same thing as self-resonance at all.

Instead of replacing the transformer,  you can take your transistor out and replace it with a 555, if you set it to switch at the resonant frequency.
The inductor doesn't know the difference.  although the 555 has its' own internal capacitance, so this will change the resonant frequency slightly.

So all of your links and stuff about self-resonance do not apply.   
MileHigh

It applies if you apply it.

I attached an annotated series of waveforms for a Joule Thief.

The red arrow shows the moment the transistor switches off.  You can see how the current that was flowing through the inductor the moment before the transistor switches off becomes the current flowing through the LED the moment after the the transistor switches off.   Then the whole process starts all over again when the inductor is fully discharged.

Do you see any "resonance" in that timing diagram?  The answer is that you don't, you are looking at a switching circuit, a.k.a. a "pulse circuit" and there is no resonance at play.

Yes I can see that by your waveform, its not sin   <---- fix that before you continue
