Well there must be some power used by the circuit and one might think the crystal would use some...so try taking the crystal out.
 
That's what I did, along with changing the 1K resistor to a 1000uH axial inductor, following Lidmotor's lead.

Ladies and gents, we have a new Exciter circuit.

Hi slider thanks for share. is this point in the blow picture must be connected together ?

erfandl - Yes, that point is connected. I should have put a dot really to denote.

shylo - Most often the answer is yes, to a point. Those 4 may be the max but quite often another could be made and they all have that intensity. Then if a 3rd such load is made, all 12 LED's would dim down by a noticeable amount. Quite often there are demo's of a bank of say 40 LED's all glowing brightly from an Exciter, the thing being that number 41 may begin the dip. It's about the amount of RF being utilised and a maximum draw point that affects all loads.
I like the idea of the caps...unused energies could periodically dump with some kind of zener circuit (as sometimes seen on Bedini SSG's) back to the input. It would then work as a harvester if tuned to that max RF usage point.


I tried the WTF (What's The Frequency ?) Exciter up to 20V last night.
It does best at 12V for noticeable improvements, being able to use the Doc's clip lead technique to gain a large area of field energy.
Today is going to be about changing the 'L3' for better running of the DT mains bulb and looking into how much of a frequency change can be derived from that coil with different turns amounts.
Another will be made as a fresh build, using a replaceable axial inductor too.
Interestingly, at the moment this circuit sits between several other Exciter circuits for initial frequency range. SWES and other pancakes tend to run at about 500kHz, Slayers tend to run at around 2MHz, this one is at 6.7MHz, then we have the Doc's 13.6MHz. 
I also think the LED in the feedback to the Base of the transistor will function similarly to the indicator of field strength LED of Slayer Exciters. At 12V it's always on and might vary with tunings. But one function is that it's protecting the Base with the light output.

All----I hooked up my crystal circuit to a scope today to verify that I was at the right frequency and wave form.  I am.  When I get my function generator in the mail it should produce similar results ---I guess.  Hooking that up to the tail end of mt setup should light up some leds. We will see.
  Dr. Stiffler made a comment on my last video and stated that the exact frequency is 13.6 but that I was close enough at 13.56MHz.  My cheap computer O- scope showed a good sine wave signal from 13.4 to 13.7 MHz.  The spectrum analyzer function showed a tall spike at 13.5 which looked very familiar and was what I was hoping for.

   Here is what my scope showed me today:

Cheers,  Lidmotor

before the crystal circuit parts received, I testing the extracted LED from the filamnet light. driving the LED with a super joule thief circuit and a 2.7 volt 500 farad supercap. the LED is running for 30 min
Tomorrow testing with crystal circuit and share the result. 

I designed a small Colpitts 6.7 Mhz it draws 2 mA.
The intended to be used with 6.7 Mhz crystal then a doubler 2nd stage.

Looks like Stefan hasn't solved the images thing, following the board maintenance message...oops.

uV - I believe the Doc started off with a Colpitts, then refined and refined.
My SEC 18-1 should be shipping by Monday and can't wait to see what a real one does !

Lidmoter - Most definitely, in my opinion. For one thing, with a very efficient circuit we could build our
own readers into watches or as a cellphone accessory etc.
There was some discussion a while ago about tracking rodents in a house and a circuit could have a loop
that tagged mice/rats/things would run through. The tags are cheap enough to log each creature and its
movements. Another use would be for a power supply for example. Put a tag on the object to be powered
and fit the circuit to the power supply. As the device is brought close to the power supply, the tag is read
and its number is used to set the output voltage and current.

Related to some of that RFID talk is something within my latest video upload.
A credit card styled Stiffler loop, that has a 360 degree ability for wireless energy pickup.
What i've done is to rework the WTF Exciter to not need the clipleads and now uses 3 coils.
It's edging toward understanding and building something more similar to Dr. Stiffler's circuits.

   Mikrovolt:   Did you make the circuit, or are planing to?    I would think that that would be a better way to go, as it has a feed back circuit.
    Let us know how it goes.
