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.

----Lidmotor

Lidmotor,

thanks for pointing to this old video, he seems to be going in some specific direction.
Thanks also to RAMSET in the followup post for the link to the latest Dr. Stiffler video here:

https://www.youtube.com/watch?v=lxRbckLedjU

I tried to replicate this setup/test and build me 3 L3 coils (16mm diameter former, 72 turns)
which measured to be 26.7 (2x) and 27uH.

I put the 2  26,7uH coils on a wooden rig so i can change the distance between them (allthough that
seem to have little influence on the leds output).

Using the FG at first, set at 20Vpp, sine wave, 13.6Mhz and using the red lead only.
Input to the first L3 coil goes via a 1 Ohm csr to take some differential measurments.

Screenshot shows the signals across the 1 Ohm csr (blue input side, purple output side, red math function Blue - Purple).

Video about this test here: https://www.youtube.com/watch?v=gEhW7oQyHrA&feature=youtu.be

I see very little or no difference in signals across the csr meaning no additial load (current) seems
to be drawn from the FG with the L3/leds combo inserted and lighting the leds (rather dimly).

Itsu - Good point about the crystal frequency, thanks for the pointer.
Am using a C3198 in the circuit, broadly similar specs. The 3904 is a bit faster but the C3198 is 80MHz rated. hFE is more on the C3198 which could factor for the Base components. In fact, i'll just swap in a 3904 and take that bit of the equation out !
Will swap out the crystal for lower values too :)

Hi Slider,
Try to connect a choke coil of about 47 uH to 220 uH in series with the collector resistor, this will enhance amplification factor at 13.5 Mhz.  The 4.7 k to 6.8 kOhm in the collector have much less values at that frequency than at the lower frequencies, with the series L the AC impedance increases on which the transistor can amplify.   

What DC supply voltage can you assign for feeding such voltage amplifiers?  What is the maximum DC output of the step up DC converter you have?

Itsu:  Glad to be of some help with the original L3 coil specs, I appreciate all of your efforts and the good work that you share.  You and Gyula (excellent knowledge and patience) provide very good technical info
to learn from in your back and forth team effort.  Thanks to you both, I'm sure there is much more to be learned here.

Gyula - yes, thanks so very much for your continued insights. I'll certainly try the inductor.
Thinking about this, Lidmotor made reference to a regular Dr. Stiffler wound L3 being approximately 100uH...could that be used ?
Am guessing that there wouldn't be an advantage of it over an axial type though in that spot.
Output of the booster is 15V, it can go up to approx 30V.

Hi Slider,

Yes, quasi any kind of coil having any inductance from say 20 uH to 100 uH or higher could help increase the impedance in the collector. This is a good reason again to visit the shed...  :)   to find some RF coils on that board with the many crystals.
If you find that such a coil causes only a little increase in collector voltage amplitude (monitorod on your scope versus the negative rail),  then connect some more similar in series. 
You can also use that coil you refer to, if nothing else.  Or if you have an RF type ferrite core, then just wind 20-30 turns on it from any enamelled wire and see the amplitude. Radial or axial type chokes are also useable here.

What is the output unloaded amplitude of your AD9850 sig gen around this 13 -14 MHz?

Playing around with my 3 coil setup.

Now measuring not the input, but the output to the led strip.

Using the FG it turns out that i have 18V dc across the leds turning them on faintly.
I compared with another similar led strip attached to my PS set at 18V dc.

Lateron switching over to the crystal oscillator instead of the FG.
It will not light the leds directly attached to the 3 coil setup, only via a capacitively
coupled setup (double sided PCB touching the input wire isolation).

The output on the led strip is the same as when on the FG, like about 18V dc.

Screenshot shows the purple and blue signals being the plus and minus side of the led strip,
with red the math function blue - purple to show the resulting DC voltage (18V).

Hi Itsu,

The 18V DC is created by the AV plug diodes across the LED diodes (7 LEDs in series and this is in parallel with another 7 LEDs also in series). You know the voltage - current characteristics of LEDs are like that of Zener diodes hence the 17.8 to 18 V DC level automatically developes across the array (LED string).   Seemingly the basic 3 V forward voltage for a single white LED is not valid here because 18V / 7 = 2.57 V only, instead of the 2.9V to 3.3V range but I think this lower value comes from the parallel connection of the two series strings. (like for Zeners or for normal diodes the parallel connection does reduce the original Zener breakdown or forward voltages)

If you connect two such LED boards in series to add their '18V levels' and feed them with the AV plug, then the input RF energy may be able to light them both, albeit they maybe would not have similar brightness than in the single board case. And you would then see a 33-35V or so DC on the scope Math. 

By the way, I assume if you connect an electrolytic cap across the DC wires of the LED board with the correct polarity, then it would serve as a puffer capacitor for the AV plug diodes and maybe you could check the DC level not only with the scope but with a normal DC voltmeter. A 47 to 100 uF, 25 or 36 V rated electrolytic would be ok for such test. (Notice: if you remove the LED board from the puffer cap, then a 160V DC rated capacitor should be used to handle the unloaded DC level from the AV plug.)

Regarding the need for a capacitive coupling when the xtal oscillator drives the 3 coils instead of the FG, I think also the input of 3 coils may represent a low impedance and loads down too much the toroidal tank. Perhaps you can see this on the scope what happens to the near 100 Vpp across the toroidal tank when you attempt to drive the 3 coils.

Could you use a low pF value trimmer capacitor instead of the PC board? I mean a few pF, max say 10 pF. To make the tuning of such capacitor relatively hand_effect_detuning free, you could make a 'trimmer cap' by twisting two enameled wires together, say you make a 10 cm long twist and leave the 2 wires open at one end. Then connect the two other wire ends as a coupling capacitor between the tank and the 3 coil setup. To tune such capacitor, just cut down the open end of the twist gradually say by 1 cm or half a cm at a time and see the brightness.

Nice experiment by the way, thanks for showing.  Would have one question: what is the LED board current when you drive it from the power supply 17.8 V DC?

Gyula,

thanks for the comments, i will digest them later this weekend.

The question you have i can answer, as the current pulled by the PS at 17.8V was 2.2mA.

Measuring the current from the battery feeding the oscillator was fouled up by RF? as i could not get
a correct reading.

And another reply for Gyula :)
A 100uH axial inductor was tried and unfortunately has pulled the output further down.
Will try various other methods, including winding on a ferrite core and seeing how the output changes with increasing winds. Will start at 1 turn.
Sorry about the delay, been publishing books. That's 4 in the past few days, 2 of them today.

Here are 2 scope shots.
The first is the 13.5225MHz 2 pin crystal circuit output running through the boost circuit.
The second is the AD9850 at 13.6MHz.
Scope probe is on the 100uH output from the Collector, other end is on the Ground of the boost circuit.

   I've got my oscillator going, and lighting an led bulb on an AV plug. I think that that bulb may have been an AC bulb before being gutted.  My best output when running on 12v, so far, has been 39v, at the collector/emitter.  But, for some reason, the voltage starts to drop after a minute, or so.
   I've got it lighting on 12v, and just being careful not to overheat the transistor. I tried adding a 150K resistor in line with the 100k resistor that's on the base, but it would not start. And so I removed it, until I can find a more suitable one.  I've also, just had my first peak at seeing a wireless field effect, from this little oscillator. Lighting an led/AV plug an inch or so away. Finally!!!
   I'm excited... about my Exciter.

Thanks for the screen shots. Everyone having fun.  Hope you will forgive this comment, the projects are progressing nicely.
Some of the problems in years past has been matching first stage to the second with SG, variants, the nature of AC at RF.

I tried to find a video a professional good setup Zzz and also a hobbyist instruction so we can determine a good
impedance match.  Using a toroidal ferrite is one method of joining the signal to the amplifier for example.
The math and a little adjustment can give an outstanding result. An efficient transfer of energy.

Hopefully this will ad some content latter with Doctor Stiffler's concept and approach also not without electrical science.
The projects move toward understanding the SEC 18 hopefully get more definitive as it goes. (L3= ?Z) Crystal oscillator ?Z
On Impedance matching. Where to start ? output impedance, or input impedance, or maybe back and forth in small approximations.
Example: 10,000 ohm high impedance and a 300 ohm low impedance example could possibly use some math at first.

Slider,

something is not right i think, the signals are to small and wavy.
Are you sure your probe is ok, like is the tip firmly attached to the probe and/or is your ground lead
solidly attached to the probe (the lead sometimes breaks within the isolation).



Nick,

way to go, but are you running at 7.25MHz?




Microvolt,

thanks for the refresh on impedance, i think it will be important to take some impedance measurements of
the severall parts/components.

   Itsu:   
   I'm using the 7.2MHz crystal for now, as it shows the highest output at the led bulb. The oscillator will also run on the 13.5MHz crystals, but not as well. As that crystal runs the oscillator a few volts lower, like 32v, instead of 39v, like the 7.2MHz crystal.    Wireless field effects start to show up at around 40v, on, but are too weak below that voltage.
   Slider: I think that your scope's negative probe may not have been connected.
