Itsu--  I agree that at this point it is difficult to know which way Doc is going with his experiments.  I found this video dealing with capacitive power transmission using just the signal from a function generator and it may apply to what we are looking at:

https://www.youtube.com/watch?v=YegIW-1hbvQ

NickZ---  It looks like you now have things working right.  Any thoughts about it?  What do you think is happening?

--Lidmotor



   Lidmotor:  Not much, it's still a very low power system, and I don't see much advantage or use for it, as yet.
The actual light output is not much to right home about, either, and this circuit is not going to save any money on my power bill.
Nor do I see any advantage in the "loop",  over a direct connection. A direct connection is better, and stronger, like just connecting the leds to a battery. Otherwise, it's just a very weak although efficient Exciter circuit. 
   I will continue on for a while longer, to see what the Doc has up his sleeve, if anything.

   You mean, how much current it will consume, compared to how much light (lumins) it can provide???
   That will be an interesting test. The "big picture".

   Using only LED bulbs will limit what the system can do.  As compared to my HV Kacher circuit, running off of the same 24v batteries. Which can light a 100w incandescent bulb, or many LED bulbs, at a much further distance from the source.

   I'm more interested in light output, than a limited output, in the name of efficiency.
   Good luck with your tests. I think that this crystal circuit needs some power behind it, to see any use able effects.
I already have "night lights", and I'm not looking to make more of them. So far, I don't see the Doc showing much light output, yet, as compared to the same 120v led bulb on the grid.

   BTW:  No need to capitalize the text, we hear you just fine.

NickZ and Seychelles--- OK for guys like us the meaning for this 'light' project has a more real world meaning than most.  It is all about lumens per watt and can we light up our place on a small amount of power.  For me I am looking for a light on a small sailboat 30 miles from the grid.  For years I have worked on these light projects hoping to solve my lighting problem using a design we worked on here at the forum.  Some worked pretty good and I did use them on trips but now I am using just this simple $5 solution.  It is basically a rechargeable 130LM led solar powered light.  For what my wife and I need on a 4 day trip this gets the job done.  There are several versions of this light but this one has an internal 850mAh Li battery, red led charge indicator, on/off switch, and the connectors are compatible with normal USB power banks. 

  I know that this is off topic but I thought I should mention something I have found that really works.  On our 32' boat we use two of them.  The small solar panels are placed in the cabin window inside the boat and charge up the lights during the day.  They do not need direct sunlight to charge.  We use the light for 3-4 hours each night.  We are at 34 degree N latitude and the summer sunlight here in Southern California is a reliable free energy source.

You can find them on EBay for $5-$8 delivered.

I just had enough 1n4148 diodes to complete this dual loop setup (2x 16 diodes), so i decided to replicate Stiffler his latest setup.

2x leds strip in series with a single led inbetween, driven by 2 diode loops 16 diodes each (1n4148), powered by the L3 coil via 2 100nF caps.

It seems indeed that each led (strip) is taking what it needs to just turn on, 2.57V for the single led, ±21V for each ledstrip.

Screenshot shows the voltage (yellow) across the single led, current (green) in the input line to the leds.

   Does any one have an idea why the leds are only taking in 2.5v? And will not fully turn on to 4v. So the output is not able to deliver the full amount to the bulbs, and therefore the brightness is reduced to only the dimmer 2.5v level.
   Thanks for hanging in there, Itsu. Much appreciated.

Hi Itsu,

Thank you for doing this test.
Would like to ask that out of the double loops have you checked the current waveform in any of the single loops how they look like?  I ask this because your current probe embeds both of the loop wires simultenaously as you showed. I know the current should have the same shape (in theory) in both loops and I also think if there is some difference say in amplitude too, then it may come from the small differences in the diodes not being identical to the last mV. And very likely the current amplitude in any of the single loops is only half of the measured 2.85 mA RMS, can this be correct?  (I mean the two loop currents seem to be summed via the common series LED boards.) 

Nick, The LEDs are only taking in 2.5 V (to 2.7 V as the Doc mentioned) because the forward current flowing in the loop is only so small that it is able to bias the LEDs only that small voltage. A white LED needs about at least 3 V to 3.2 V forward voltage to give a decent brightness, this normally involves any forward current between say 10 mA and 20 mA for a single LED.
Notice that the 4 V forward voltage you wrote would already overdrive a normal white LED and kill it in a short time.  MAximum a 3.5 or 3.6 V should be involved.
Obviously, the near or close field from L3 coil is not high enough (maybe yet) to create the 3 to 3.2 V forward voltage which would involve the higher loop current hence the higher brightness, I agree with you.
 I think Itsu drove the earlier single loops with DC input voltage to compare it to the measured AC loop current and he found them within ball park to have similar brightness. (If I do not recall this correctly, then Itsu surely chime in.)So simply there is still not enough RF juice to drive the loops.
Here I have to mention the Doc's 'explanation' on the LED self capacitance which would provide the current for each LED so that the brightness should come from the potential the self capacitance continuously picks up from the field and discharges it via its own LED, this may or may not be correct. To check this, you would need to connect a small value capacitor across each LEDs to see any change in brightness. The small value cap could be say a 22 pF or 47 pF for each LED in parallel.  OF course I may be mistaken with this latter.

   Gyula:   Well, it may be that there is not enough juice to fully power the leds, but, I have provided over 100v from my crystal oscillator, and still not fully lighting the leds.   It does not seam to make much difference, if the input is 12v, 24v, or higher.  The leds are not being fully lit, and the actual brightness suffers.   I do not have the right 120v led bulb, with the metal backing. But, my series connected 10 led bulb will light, even without having the metal backing. As the led PCB all have the copper plating on the board itself. Which may not be as good as the additional aluminum backing, but works to some degree.

   All I'm saying is that there is little use able light coming from my crystal oscillator set up, for me, so far. Comparable to a single or maybe two fully lit small led bulbs worth of lumins. 
   I think that the above may be due to a less than perfect match and sync between the oscillator, and the L3 coil.  Or not?
But, I don't see that the Docs bulbs are being lit anywhere close to fully on, either.

   We need to test further the idea that the leds are what is producing their own light, from the tiny amount of input provided.As even that additional power to light the led bulbs has to come from,  somewhere, also.

Gyula,

the both loop currents basically are identical and half of the total current, see screenshot below
which shows in Ref1 (R1) the total current, and in Ref2 (R2) and Ref3 (R3) the both seperate currents.

When using the oscillator instead of the FG i can get some more voltage across the leds and they get a little brighter then.

Nick,  okay on the as high as even 100V from the crystal oscillator but let me ask: what DC voltage amplitude would be needed for your LEDs to get what you consider already as full brightness, did you check it too?  Your 10 LEDs in series may need say 31 - 33 V DC to operate with full brightness from a DC supply I would think and then the current draw would be say around 15-20 mA ? (If you check this, make sure to use a few kOhm resistor in series with the LEDs to protect them from extra current draw.)

Now I assume that when you use an L3 coil that creates the near field (rather than the choke coil in the collector), then you make sure that the L3 coil should be spot on the crystal frequency, otherwise the use of L3 has not much advantage. You surely know that anything near to L3 may detune it. And if you use a ferrite piece to fine tune L3 then the core material should have low loss at the crystal frequency. RF powder iron toroids could be used if you slip them close next to each other onto a piece of plastic or wooden rod. Such RF toroids I mean:
https://www.ebay.com/itm/282774499025  and data sheet http://toroids.info/T50-6.php
Of course these cores when you push them into an L3 coil, then L3 in itself should have already a higher resonant frequency than the crystal frequency so that the cores could reduce the original coil frequency. Also, when any so called 'top load' is connected to the floating free end of L3, it also reduces coil frequency, so the use of the cores should be considered accordingly, may be some turns should be removed. Sorry if you know all these fine tuning details though, and your thought on the match between the oscillator and L3 coil is correct.

The energy to light the LEDs should come from the RF field the L3 coil produces from the oscillator. Unfortunately, this is a lossy conversion process: one is the DC input to the oscillator (oscillator conversion efficiency), the other is (radiation efficiency of L3) the field of coil L3 is all over in its vicinity in quasi every direction in the near space i.e. the field is not concentrated solely for the LED boards and / or LED wires, it is spread over in quasi every direction, the strongest field being around the top end of the coil where the voltage maximum should be.

 Itsu, Many thanks for checking the two loop currents, that is how I thought.

The signal transistor such 2N5179 make great oscillators however we can modify an oscillator for good transfer using a ferrite torus which allows the density of
the magnetic flux to build which is like a very efficient small dynamo.

The power transistor now has what it needs to amplify. The 2N7000 has been shown to improve efficiency in D or E class mode. It was a good suggestion
made earlier here. In some cases found 40 % increase. By not over driving the signal transistor, simply moving the mA to the power transistor.

I was very excited about the latest video on bidirectional loop in fact could not sleep, a lot of possibilities. The ongoing projects are also making great progress paving the
way, we will definitely be seeing better designs coming up.

The latest video has piqued interest:
https://www.youtube.com/watch?v=66KTJGlbKmM

Dr. Stiffler is using a 12V SLA, a SEC circuit, a couple of L3's, a 100ohm resistor, the diode loop and the Cree board.

What I like is the description underneath:

Doing final check on the parts to be used in the loop distance test. There will be no single wire, test will be through the earth only.


Outdoors through the earth...exactly what many have been stuck on, including myself most frustratingly for years.

Slider--When I saw Doc's latest video I thought of you right away.  We have been stuck on this idea for years and years.  I made a video of a single wire feed off a SEC to start getting up to speed with what Doc is now doing.  A number of people are commenting on how the "Stiffler Loop' works and one guy thinks that it is basically a 'Ring Modulator'.  The more I look into it the more I like that theory.  Here is the video I did today on my one wire feed.  It deals with how the link to the Loop is done.

   Here is the basic 'Ring Modulator' circuit:

I agree about the Ring Modulator. It immediately made me think of synthesizers, having built analog types and their component circuits in the past.
Looking around, yep, same thing here: http://www.usefulcomponents.com/main_contents/projects/simple_ring_mod/simple_ring_mod.html
It would perhaps be interesting to throw different frequencies through, but with a dozen 1N4148's. Was thinking a couple of years ago about using blocking oscillators and other circuits we work on within music....strange music maybe  ???

If the Doc gets further than 6" from source to receiver outdoors, then my eyebrows will be on the ceiling !

Now to view your vid :)
