Hi Nick,

Yes, the best way to close out stray field from the AC mains within the rooms of your house is to turn off the breakers.
If the red LED continues remaining faintly lit, then the next step would be to take the coil + LED assembly (or your oscillator circuit as a whole) out from the room and / or from the house and see its brightness whether changing or whatever.
Watch for the brightness when removing the connecting wires one by one while attempting to take the circuit assembly out of the room.

The data provided by Itsu is based on conventional i.e. known science. The aim would be to build oscillator circuits to provide high enough RF voltage which is able to substitute a function or signal generator to replicate Doc's setup with the air core coil + LED board as he showed.  From Lidmotor and others replications and tests it is clear that there is no need to use the 13.56 MHz frequency, it is not 'magic'.  Notice that the Doc has not claimed overunity.  So far the tests I have been aware of shows higher achievable efficiency with such setups driving a LED lamp than driving the same lamp by its original off the shelf circuits to get similar brightnesses.  Efficiency for the driving circuits applied in the off the shelf LED lamps may range from say 80 to 90%, not really higher.  The conversion efficiency of the LEDs themselves from their DC input to light is a totally different question.

Hi erfandl,

What is the transistor type you are using in that circuit? 

IF you use a 1 MegaOhm resistor for biasing the base from the positive supply rail, then try to reduce it to the some hundred kOhm values and see how brightness may change. Do not go lower than say 47-56 kOhm though but this much depends on the hFE value of the transistor.  IF you find improvement in brightness when you reduced the 1 MOhm, then try to change the 30 pF trimmer and also try to add the 22 pF in parallel with the trimmer capacitor to find any chance for higher brightness. Do this trimmer cap setting again whenever you change the base resistor value down from the 1 MOhm to find better and better operation.

Gyula,

i tested with the tap on 3 and 2 turns.

At 2 turns the oscillator won't work without any virtual ground near by the leds, so i connected a cliplead again to the junction of the 2  1N4148 diodes.

I tuned for max output on the leds by turning the 100 trimmer pot and the variable cap.
The screenshot 1 below shows the signals where blue is the output (3 turns on the toroid) and purple the collector/emitter voltage.

The 100K pot was set to 18K and the current drawn was 110mA (when pulling the x-tal it goes to 150mA).

No saturation / distortion was seen, but there are many peaks across the spectrum still, see screenshot 2

The variable cap measures 37.5pF using my LCD meter.

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

Hi gyula. I used 2n2222 transistor. OK tomorrow testing with 100 kohm or lower resistor and share the result.
thanks

  Gyula:  I was wondering how you see the calculations on Itsu's device, so far.  80 to 90 percent?  Which can be obtain by any efficient inverter. Of course, no offense to Itsu. As I appreciate his tests and videos, immensely. Along with all his help.

  Well, one of the problems I see, is that these little transistors can't handle 20 to 25v. Not even 12v, without a meltdown. In order to be able to replicate what the Doc has shown when using his SG at 20v, and no ground.
Yet, even he is producing a limited output, no where near what the grid powered bulbs can provide. Maybe half the brightness, or so.   
   I can't even get an answer concerning the proper way to wind an L3, other than on a battery. Although I do appreciate that information, and Lidmotor's measurements on the L3 coil.

   So, if the Doc wants to see other people replicating his ideas, then he needs to provide the needed specs. Or at least close to it. That L3 coil, along with the crystal is the heart of his circuit. Yet, he has given no info on the coil. At least not lately. 
The Doc told me once that, "no use kicking a dead horse", and that I should get a horse that I can ride.
Because I didn't have a scope or SG, back then.  And, I'm still looking for that horse... now that I can play ball. Little league, with my limited voltage SG.
    Sorry guys, but,  I think I need a Snickers bar.

   Itsu:   I don't expect to find OU, either. But, I'm hoping to find something useful and practical in what the Doc has been showing. It would help to know exactly how the right L3 is wound.

HI NICKZ. IT IS NOT ROCKET SCIENCE STUFF, AND YOU BEING WELL VERSE IN ELECTRONIC.
IT IS AS EASY AS ABC..ALL YOU NEED IS A ROUND ELECTRICAL CONDUIT, 15 OR 20 MM,
THEN YOU NEED A PIECE OF 2 M ENAMELLE COPPER WIRE. THEN JUST WIND THE THE LOT
NEATLY ON THE TUBE. THEN YOU SWITCH ON YOUR CIRCUIT. THEN TO TUNE UNWIND TILL YOU GET THE
LED TO LIGHT, AND THEN YOU CUT AND SOLDER, DESMOND IS YOUR UNCLE.

Hi nick,  The MPSA06 was a type close to what was being studied. What we have is what we are allowed to have.
In sorting through that episode we are told to stay tuned. The real transistor is not commercially available. It has an
hfe of 400-750 and a Vbe of as low as 0.17 volts. Most of the projects do not rely on special transistors.

So there was more than what meets the eye. I do see that the Doctor usually socially concerned and careful.
He was still off and on with the big semi conductor people. That is how the corporations operate,
everyone waits on them, sometimes lifetime waiting and never getting past their lawyers that control them.
That is where the high horses roam.

I am not sure everyone followed the harmonics in general. The signal generator can be set to square wave and duty cycle
set to 25 % or 43% so that the width is set less than 50. To see the effect. The (AV) or half rectifier diodes effect can
also reduce the width of the sine. Maybe someone can show the effect of narrowing on the harmonics.
Because the negative resistance oscillator frequency becomes lowers when a load is applied it would be nice
to reuse what is left. If the harmonics behave the job is less difficult.

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

Hi Erfandl,
No, forget it, it is surely not fake.  Pay attention to all the comments GBluer made under his video and under Lidmotor's replication video.   Hint: possibility for choke coil resonance   and one of ways you can tune this oscillator is by adjusting the input supply voltage and watch peaks in brightness.  OF course, this is very component dependent.

What input voltage and power your LED board (you show for this circuit at the bottom of the previous page) is specified for? 

Lidmotor replication showed a 1 W LED probably a single LED and not an array and also GBLuer showed a 4 W LED and estimated the brightness of half of that by his eye.   I guess the LEDs Lidmotor used needs  3.5 -4 V input maximum and the LED GBluer used may also need less than say 12V (my rough estimation).

thanks for reply. input source is 3.7 volt battery @ full charged level. now I using simple white led the brightness is good but it cannot be working with 1.5 volt ( like Gbuler circuit ) output voltage is 3 volt

I wonder whether your circuit now works as an oscillator  or the 3.7V battery drives the LED via the collector choke and via the series diode to the LED?   :-\
