Dr Ronald Stiffler SEC technology

   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.

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.
