I keep trying to increase capacity at times, and made ​​a coil with an external capacitor for better tuning , resonance now caught very easily, and the amplitude of the sine is greater than 100 volts.

I am, for one, is grateful for the video. However, the biggest questions I have are all regarding the coil and the external capacitors.
You see, the ferrite cores available to us are, somewhat, different to yours. It doesn't mean that we can't make it. It simply means that we are not able to directly replicate your device.
What would really help is the actual data of the coil, i.e. the number of turns and/or inductance as well as the value of the external capacitor.

If I were to have those, I would adjust my device accordingly.
Another question is about the scope. Where do you connect you scope to and what was that frequency. You mentioned that the frequency is low, but how low is low?

I hope that you can answer these questions. I would have thought that we can help but we need to level with you first before we can go further.

Амплитуда синуса зависит от частоты, а частота от емкости. Подбирается конденсатор на максимальную амплитуду резонанса, это будет самая эффективная частота. Я пробовал от 10микрофарада  до 1нанофарада.....остальное пока не могу сказать.
Я пробую 2 последовательных CREE светодиода.
The amplitude depends on the frequency of the sine and the frequency of the container. Selected capacitor at the maximum amplitude of the resonance, it is the most effective frequency. I tried to 10mikrofarada to 1nanofarada else ..... I can not yet say.
I try 2 consecutive CREE LED.

Concerning the squeezing i can concure with TK's comments.
What if you keep the squeezing force constant and superglue two large masses to the core laid horizontally?

Я могу поделиться видео на этапе настройки, вы сами убедитесь что резонанс поймать легко, и не нужно все усложнять. ;)

I can share video during the setup phase , you'll see that the resonance catch easily, and do not need to complicate things . ;)

Hi All,

Would it be fair to view the Core, Coils and the Capacitive Plates like the following:

Note: Each Copper Shield is a Capacitor Plate.

All the Best

Yes i think that is what semenihin-77 is saying.

Then i will first try if i can get resonance with help of external capacitor.


Thank you  :)

Очень похоже на то что надо, только надо емкость подобрать по максимальному пику и контролировать потребление.

Very similar to what is necessary, just need to pick up the capacitor at the maximum peak and control consumption.

О какой ёмкости говориться, которая между 3 и 4 ножкой у 34063 микросхемы или о какой?

Maybe build a 4 sided structure from glass plates with the pot core halves glued to two inside surfaces with a small gap. The tiny amount of flexing should be tunable, as also the gap. A cutoff section extruded aluminum channel might work, but for really hi Q, maybe construct from hi carbon steel with magnetically insulating risers.

I'm thinking of gluing the core halves to the inside poles of a U shaped piece of non-metallic hi Q material, open portions of the cup cores facing each other, gap adjustable. This could make for a dandy parametric inductor.
------------------------------------------------------------------------------------------------------------------------
BTW, the above posted schematic (circuit.png)makes a bit more sense than any of the schematics I've seen, the transistor VT1 acting as a synchronous rectifier switch to utilize the hi Q ringing of the tank circuit and add to the 470uF.

As shown, with a low frequency drive for the transistor, and un-synced to the main oscillator, it is hit or miss rectifier, hoping to  close on the peak of a positive excursion of the ringing frequency and open at the peak of the last positive, it will add 1/2 cycle of the ringing energy to the 470uF storage cap. It will zero to a null, operating randomly unless the LF oscillator can lock to a subharmonic of the main oscillator.

It would.
...and if you had a short HF low current winding there, its inductance would reflect the instantaneous width of that gap. A very useful information. 
The MC34063 can extract this info as an easily integrateable pulse widths, when operating in constant current mode with constant load.

What is your idea how to utilize the kinetic energy gained by the core halves?
