I wondered too :|
In your above photos on the circuit I cannot see the capacitor which originally connected between choke L3 (labeled as negative out) and the negative supply rail.  That series LC gives the feedback for the oscillator, without feedback there can be no oscillations.   Sorry if you have that capacitor on the board in the above pictures but I cannot see it.   :(
Another issue:   In the original schematic, the 1N4148 diode output (labeled as positive out)  is connected to one of the LED pins.  Where did you connect the other pin of the  LED ?  Originally it connected to the variable capacitor and the negative output of the choke L3,  but where did you connect it?   It is lit....   and this is why I asked whether it is lit by oscillations or ??

Have done a lot with the GBluer circuit over the weekend and can make some observations on your struggles erfandl.
My own version works, but hasn't the output brightness shown in either GBluer's or Lidmotor's versions.
1.5V AAA powered, using 1000uH axial inductors.
The circuit doesn't start up on its own with my breadboard build, it needs the transistor Collector to be momentarily grounded.
Tuning with an AM/FM radio variable capacitor sort of works, but only from max brightness to minimum brightness, with no sweet spot.
As the var cap is turned, the ground to Base LED fades out - I note that your LED isn't on at all, so the tuning appears to be out of range at least.
It'll run an LED on an AV plug directly from the Collector.
Brightness of the whole thing increases markedly, if you sit both of the input inductors right next to each other. The circuit suddenly flips into a higher output if they are touching lengthwise.
Transistor type affects output, based on hFE and the usual factors, so it's not a switching situation.
2SC3198 is best so far, but i'll try MPSA06 and MPSA18 this morning.
Extra 1000uH inductors in parallel dim the output, which I thought was odd.

All in all, my own has a long way to go too.

Shown here with a 1W LED on the output.

yeah capacitor is connected between L3 and negative rail. the other led pin is connected to variable capacitor and negative output.

Gyula,

i will tinker again this evening.

concerning the used led strip, i found the following website showing an example and put down some specs below:
https://www.beslist.nl/klussen/d0018768908/R7S_LED_Lamp_11W_Warm_Wit_135mm.html

# Replacement for 150W 240V halogene lamp
# 11W @ 90-260V AC
# Type LED Epistar 5050 SMD   

It has 3 strips (parallel??) and i use only 1 strip, meaning it can handle/supply about 11 / 3 = 3.6W (50W equivalent)
I estimate the brightness i had yesterday on about 1/3th of it being on the grid.



Nick,

concerning the L3 coil, i found this website/picture:
http://www.tuks.nl/Mirror/Dr_Stiffler/SEC18_1.htm.html

Comparing with the 1N4148 diodes (3.5mm long) i guestimate that the coil has the following dimensions:
former diameter: 20mm
former length:   50mm
nbr of turns:    70

But its like seychelles says, its not that critical.

Itsu

   Itsu:  Thanks for the info on the L3.
   The mag wire he used looks fairly thick, and with fewer turns that what I'm using now. So, I'll try to remove some more turns, and see what happens. But, I think that to actually see the effect, we may not be very close, at all. And considering the low light output from the LED, as compared to the input source.
   Could you please PM me the shipping order number, again, so that I can verify that it is your order that has come to the post office, instead of to me house.
   BTW: Has Dr. Stiffler mentioned what transistor he is currently using on his latest tests?  No?
As the transistor he is using now, (may be that critical), in order to see the proper effects, along with a 13.5MHz tuned L3 coil.I think that it's there, that the mystery lies, and which the Doc is not mentioning.

Nick - good point, I think the presumption of any Dr. Stiffler demo is MPSA06, as uV mentioned and as are fitted to SEC-18's. But it would be good to know. I've also never seen a comparison vid of an MPSA06 and 1 of those special transistors, perhaps side by side running something.


Update: some progress with the GBluer circuit.
A 120+120 of 40AWG on a ferrite core dramatically improved the Base LED, to the point of looking 'normal' for this circuit lol
The Collector output 1mH axial inductor remains the same.
The 1W LED looks the same as it did in the previous pic, so you can tell the difference that the wound version has made.
It still doesn't auto start up with a 1Meg resistor, or any value down to 100K.
 

Update again: Holy buckets of fish...check out what happened when the 3rd axial inductor was removed and the 1W LED was connected to the Collector diode and Base (2SC3198) !!!
The Base LED was knocked out of action and the var cap does nothing, but the light output of the 1W LED is vastly improved.
No idea what it's done to the current input yet.

   Slider:   Aren't you limiting yourself to having no wireless output, by using an led as an indicator, and too low a voltage to see any capacitive or wireless effect? As you can't raise the voltage past 4v, with that 3.5v led there, as you probably already know.
Or not?

Yep Nick....was just shocked at the difference, considering it's a 1W on the output.
From here, a more traditional Slayer L2 could be put on the output is the thinking, similar to Gary's latest video.
Current measured through a 1ohm resistor this way is 27mA, so that's not so great, but is still very low for the LED brightness. Batt voltage is 1.383V
Interestingly enough, the other way around with the inductor on the output i'm measuring 32mA with the 1W LED removed, but 28mA with it in place. The Base LED remains the same brightness, but the 1W LED drops the current by 4mA.

  Slider:  Yet, that 1 watt led is only partially lit. And the small led is only limiting what you can do.
You will get a JT type of output using a 1.5v battery as the source, that's all. No capacitive wireless output.
  Is this all just about getting some light from a tiny bit of input power?  How exciting is that... 5 minutes worth.

yeah capacitor is connected between L3 and negative rail. the other led pin is connected to variable capacitor and negative output.
Okay then, your oscillator works.  Try to seek for resonance with the chokes,  especially L3 and make the trimmer capacitor to cover a higher pF range.  (GBluer indicated a 2-512 pF variable.)  The base resistance then may also be varied. 
Each oscillator has its own 'soul'...   :)

Gyula---Your comment, "Each oscillator has it's own soul."  is so true.  This latest G. Bluer circuit is no different.  Gary builds weird circuits---always has and he doesn't explain much in his video.  To me they are puzzles and going back many years I have enjoyed them.  His 'Slayer Exciter' like the Joule Thief is a classic.  This 3 choke exciter is a 'tinker toy' and meant to be played around with.  I did get the original circuit to run but quickly modified it (like Slider and Gary are doing).  Mine does not self start so I am using a BBQ lighter spark near it to jump start the oscillator.  I eliminated the 1M resistor.  Here is a tip: Just take two chokes and put them side by side and wire them up to the NPN in a regular Joule Thief circuit.  If you get good led performance like that you know that the chokes and the transistor like each other OK.  If that works then it is just a case of reconfiguring the two chokes into the new circuit.  The third choke can be replaced with a Slayer Exciter tower if you want and the cap doesn't do much I found.  Keep the 1n4148 diode and led going from the (-) to the base for this thing to run right.  I'm am not seeing the super low amp draw on mine that Gary shows but it will run down to about .6v.  Any 2N2222 type transistor works fine. Stay under 4v to keep it alive.

All--Dr. Stiffler's latest video is about using three coils resonating together ----driven by a function generator.  I think I know why he is doing this and where he is heading.  Remember these days?  Guess what that 'special frequency' is that he talks about in this video from 2011.
https://www.youtube.com/watch?v=7lbYjqU48Mw

I wonder if he had his function generator (set at that 'special frequency) connected to something near that AL block sitting on the far right side of the elevated board?  Hummm.

Even if this device was not 'self-running',as people thought, to me the fact that it worked at all is amazing.  Now that I have a signal generator perhaps I can replicate this experiment.  I always thought that perhaps he just had another SEC running near by ----but what if it was just his signal generator broadcasting at 13.6 Mhz pumped out at about 1 watt.

thanks. but there is no 512 pF trimmer available  in my country. I found only 0-120 pF trimmer. is that help me ?

Yes, it can help you.  And you can always add fix capacitors in parallel with it if the 120 pF is not high enough.  (Of course the setting range suffers.)    You may have access to old AM pocket radio in which a plastic cased variable capacitor can be found, normally such has 2 x 260 or 2 x 300 pF variables.    Or you collect a range of fix capacitors like 22, 47, 100,  200 pF and place them in parallel in gradual combinations.

Thanks Itsu.  Regarding the virtual ground to start up the oscillator: have you tried to connect the common point of the diodes to the negative (or maybe the positive) supply rail with a short piece of wire?   That my also help start up but without that longer piece of wire. 
If it works like that you may increase the potmeter setting to a higher value like 50-70 kOhm maybe to reduce dissiparion if the circuit lets it doing.
Very likely you need to retune the tank, we do not know how many pF the back plate of the LED board introduces into the tank, maybe it would detune the tank too far from 13.56 MHz, so keep this in mind.  it is possible the variable capacitor should be turned to its minimal pF setting or even to remove it and yet the back plate capacitance would be still higher than the originally needed 30-35 pF. 

Addition: with the tap at the 2nd turn, the 22 pF capacitor between the collector-emitter may need to be modified to a higher value to increase feedback, this way the oscillator may start-up without any virtual ground, this can be true for the tap at the 3rd turn too.   Try to set not higher than 60-70 mA collector current but that may be really needed for the 230V LED board. 

Do you have the specification of the LED board the manufacturer gave on it?  Input voltage I guess is 230V AC originally.   Now is the brightness we see close to the brightness this LED board produces from the mains with its original internal circuit?  I think these questions would be put by Nick too...   ;)

Thanks,  Gyula

Gyula,

Still tap at 2th turn.
Replacing the virtual ground cliplead by a short wire to the negative or positive rail does have the same effect, the leds turn on brightly.

In this state, i can reduce the 100K pot setting for 60mA input current (32K) but that gives less brightness on the leds.

Replacing the 22pF cap in the above situation by a 47pF or a 100pF one does not make the oscillator start without a virtual ground (short lead to + or - or cliplead).



Going to the tap on 3th turn starts the oscillator only when inserting 100pF across collector/emitter (so without any virtual ground) but with much reduced brightness on the leds (100K pot still at 32K drawing 70mA).

Hi Itsu,
Many thanks.  This may mean the series capacitance of the back plate of your LED board towards the conducting LEDs and the two diodes common point is small enough so that the variable capacitor can still be tuned for max brightness, I suppose?
Okay that a smaller current yields less brightness, I thought to reduce it so that such changes should not damage anything.
