Pulsed DC JT by TK Labs
« on: October 10, 2021, 08:14:20 PM »

This is an unknown device created by TK
It appears to resemble a joule thief (at least that was my take on it)

Im not sure if this device was intended to operate in this mode,
However, attempts to fire this up using constant DC have thus far failed.


So i am using a high frequency pulsed DC i optionally added some external inductance in the power lead using a bi-filar tesla coil that TK made. (im sure any coil would have sufficed)


Heres a short vid

Thanks for sharing this. Interesting deployment of the spark gap. Your series wound bifi coil should be upping your voltage tremendously, and taking advantage of it with a spark gap makes sense to me. The spark gap, following the logic of Don Smith, should render your setup an open circuit. Being no longer closed, it can access, via the spark gap, the ambient charge present in the electrostatic environment. I would invite you to consider putting a larger LED load on this - this, I believe, would give you a clue as to whether the bifi coil + spark gap combo has rendered this setup load-driven, versus battery-driven.

If you can put an inline volt meter after the battery's positive lead, you may find the battery draw actually dropping as you light up a load, indicating that the draw is coming not from the battery itself, but from the electrostatic environment.

Again, thanks for this - very refreshing with possibility.
Regards,
Bob

So i took some measurements around the circuit
The bifilar seems to be ramping it up from 0.2v to 0.5v
But only with the gap, if i directly connect the battery
Im reading 0.2v and the device doesnt power up under 0.3v


Theres a 0.1v drop across the shotkey and
im not seeing any voltage drop across the lit LED
at least not that my meter can detect.
0.4v before and after the led to ground, and across it.


So its holding right in its’ operating range.
I have not yet needed to push the ferrite deeper into the variable inductor
We’ll see how long this battery hangs in there

Update:


Day 6, the battery is finally showing signs of depletion,
Ferrite is now 3/4 inserted before it kicks on, and not quite as bright anymore


Battery has dropped to 0.18v
(still reading a steady 0.4 across the led)


its an extremely efficient little JT, specially since i can adjust the inductance
and ‘tune’ it back in.


For those that don’t understand what that means:
this is somewhere close to the min cut-on inductance for the transistor w/ the circuit
(generally speaking)
in this range is where you will find the most efficient rlc frequency
brightest light, max output with min input, etc.
and where you will find a resonant node for the inductive part of the circuit.
To visualize this on a scope, a secondary winding is useful to separate the inductive signal
from the digital switching spikes of the transistor.


this can be cleaned up by adjusting the gate resistor, to achieve a nice waveform
(on vs off switching times and waveform symmetry)
Note that doing so will change the frequency requiring an associated adjustment in inductance
to ‘tune’ it back in.

I don't use batteries anymore and only use input/output capacitor banks. Capacitors do not lie and are natural integrator-accumulators. Whatever the voltage or current going into or out of the capacitor it always shows us the energy based on the voltage change ie. Energy = 1/2 C V^2. We can also get an accurate measure of the energy flow instantly with out having to wait. Ergo... there foolproof.

I use a voltage divider or opt isolator on the input and output capacitors tied to an Arduino to monitor the Energy and the change in energy which gives me power and current flow. I included a picture of my older basic setup below and there's not much to it. I also use a data logger on the Arduino so I can save my test runs however the new Arduino IDE has graph plotting. In the picture below the whenever the total energy in the input/output capacitors changes we know whether were losing or gaining energy within the system.

Another neat trick is using the input/output capacitors to easily loop a circuit and use a separate isolated PMW circuit to add energy to the input capacitor to maintain it's voltage. Thus whatever power(VxI)/energy(VxI)/T is added to the input capacitor to maintain it's voltage is our total circuit losses. As I said it's basically foolproof and if the capacitor(s) voltage is dropping we know as a fact there is no gain to be had...period.

I just got tired of all the BS and wanted a foolproof method to show me where I'm at with respect to an energy loss/gain. That's what all this is about isn't it?, to know where were at and what direction we should be heading. It's strange and while many are preoccupied with current or voltage my only concern is Energy, Energy is what defines what happens in these systems. Understand Energy and Free Energy becomes much easier to understand...

With respect to the graph in my last post...
Capacitor C1 is discharging into C2 through a 1" ferrite toroid at a frequency of 1 kH @ 50% duty cycle.

We see the energy E1 fall on C1 as the energy E2 on C2 rises. The total energy E1+E2 also falls about 20% which is our total system losses. We also see E1 falling more than E2 is rising which is why E1+E2 is falling. So based on how the energy changed we can say one energy cycle was in fact only 80% efficient.

What neat is that the energy transfer can have any frequency,  waveform, voltage or current and this system will always show the exact efficiency. It can do the same job as the best DSO or power analyzer for a fraction of the cost.

It can do this not by using complex calculations and measurements but the nature of its components. That's pretty neat in my opinion...

O.U. as reactive power,  there is little doubt.

https://www.youtube.com/watch?v=MNzbc-N-e9c

IF someone could manufacture an     LED   to    photo diode     combination
that is          high efficiency.

i.e. like unto an optical isolater... 

Perhaps one that is restricted to a narrow band width of light ? 

Real power, other than just for lighting LEDs could be obtained ?

We just need to turn the corner and we are there !
   Vamanos !

@ Floor,
I like your idea: LED with Photo-diode combo......
For information see/read below the details.
https://electronicscoach.com/difference-between-led-and-photodiode.html

Difference between LED and Photodiode
The LED operates on the principle of electro-luminance while photodiode works on the principle of the photoconduction.
In a Light emitting diode, when electrons and holes recombine, the energy is released in the form of light.
Thus, it is termed as Light-emitting diode.
On the contrary, photodiode generates current when it is exposed to the source of light.

LED and Photodiode are reverse of each other. LED generates light with the help of charge carriers while photodiode generates current due to incident photons. In a nutshell, LED converts electric energy into light energy but Photodiode converts light energy into electrical energy.

Comparison Chart

PARAMETERS   LED (LIGHT EMITTING DIODE)   PHOTODIODE

Biasing Mode   Forward Biased Only   Reversed Biased Only
Problem of Leakage Current   No leakage current   Reverese saturation current is significant. Dark current flows when no light rays are incident on it.
Applications   Indicator in AC circuit, Alphanumeric and Numeric display etc.   Switching, high speed counting, ac coupled signalling etc.
Definition
LED
LED is an acronym for Light Emitting Diode. It is formed by a forward biased PN junction. When electrons in N-type semiconductor combine with holes in the P-type semiconductor, they release energy in the form of light or heat.

Light Emitting Diode

In germanium and silicon semiconductor the energy is released in the form of heat or light. While in semiconductor materials such as GaAsP and GaP, the energy is released in the form of light. Therefore, these materials are utilized in the construction of LED.

The electrons in conduction band possess higher energy than holes in the valence band. Thus, recombination is possible only when electron gives some part of the energy. This concept is called electro-luminance and LEDs are based on this.

One more crucial point in the construction of LEDs is the usage of the thin film of Gold. This is because the light if enter into the internal structure of LED will reflect to the top surface by this gold film. Thus, the intensity of light emitted will be high.

But if the semiconductor material is reverse biased, i.e. the P-type semiconductor is connected to negative terminal of the battery and N-type is connected with positive terminal of the battery, then LED will not emit light.

LEDs do not operate in reversed biased mode. If we operate it in reversed biased mode, it may lead to deterioration of LED.

Photodiode
A photodiode is also made up of PN junction diode, but when the PN junction surface is placed in the light source, the charge carriers in the photodiode get energy, and they start moving. The movement of charge carriers in the diode results in the generation of electric current in the photodiode.

Photodiode

This process is termed as photoconduction as the process of conduction is possible only using Photons. Photodiode operates in reversed biased mode.

The entire structure of photodiode is placed inside a plastic case so that the light radiation do not get scattered. One of the surfaces of the plastic case is chosen for illumination by light rays, and another surface is painted black. The intensity of light radiation will decide the intensity of electric current generated.

Based on this principle of photoconduction, phototransistors can also be made. Instead of using diode we can use a transistor, and electric current can be generated using photons.

Key Differences Between LED and Photodiode
Function: The function of the LED and Photodiode is contrasting. LED emits photons due to electron-hole recombination, while Photodiode provides energy to electron and holes by exposing itself towards light radiation.
Operating Principle: As we have discussed above the operating principle of LED and Photodiode is also different. The principle on which LED works is called Electro-luminance, i.e. Lumination using Electric charges. While the photodiode works on the principle of Photoconduction which means conduction using photons.
Biasing: LED always operate in forward biased mode, it cannot be operated in a reversed mode as it will destroy it. A photodiode is a device which operated in reversed mode only.
Conversion form of Energy: LED converts electrical energy into light energy and photodiode converts Light energy into electrical energy.
Material Used: LED is made up of GaAsP or GaP. Germanium and silicon semiconductor are not used in the manufacturing of LED. Photodiodes are made up of Germanium and silicon semiconductor.

Conclusion
LED and Photodiode, both are two terminal devices, but they differ in their working mechanism.
They are completely different devices. One generates electricity and other generates current.
The intensity of light produced by LED is directly proportional to the applied voltage.
The higher the voltage, the higher will be the light intensity.

Similarly, the intensity of electric current generated by the photodiode is directly dependant on the intensity of light rays falls on it. But a term is associated with photodiodes, i.e. dark current, this is the current that flows in the reversed biased photodiode when no light is incident on it.

@Kampen
Thanks for the thorough breakdown.  Next is the question of maximum efficiency
available / achievable.

This is incorrect and voltage(an electrical pressure or difference in potential) is the reason a current (moving free electrons) flow. One thing cannot generate "electricity" and not voltage or current because these two components are electricity.

The intensity of an LED is a function of power (V x I) and Energy(V x I)/Time. This is true because we can have power but if it only occurs for 1 microsecond then the energy/intensity will remain low. Energy matters...

Here is an excellent resource which explains the concept of electricity and energy...http://amasci.com/miscon/elect.html
