Hi folks
I left on this idea a little provoked by Joel's Peg cell. I was thinking about his reasoning when he started building this little Peg named source to break the dipole.   I think he managed to get this cell with a very high internal resistance(I hope I'm not wrong about that) I took the information more on the fly, without documenting the information very well. 
So I thought of a simpler variant which is the one I'll show you right away.
I sincerely hope I can have time to develop this attempt which constructively is completely different from the Peg cell, but would have the same goal. I repeat... I hope I'm not wrong in my judgment. It can also be an interesting topic to approach. We will see...


Good day to all.    realco.

Hi Realco,

Very interesting experiment !

Let me see if I understood it right.

So you've been inspired by Joel's method of applying pulses to his quantum cells but you're actually using natural quartz instead of cells, right ?

Applying 36 V pulses (with 0 current) to a natural quartz crystal and makes it responding back with 342 V.

Basically your crystal in amplifying the input voltage pulses almost 10 times ?

This makes me think... what if I convert the voltage produced by my cells to pulses and apply them to a natural quartz crystal so it can amplify those pulses almost ten times ? Because these cells are also producing voltage with almost 0 current just like your input. It's true, they're not producing 36 V, just about 1.2 V - 1.4 V but if the crystal quartz can amplify this voltage almost 10 times it would be great !

Two questions:

  • Do you think it will work with any natural crystal quartz which can be bought from the market or it's a specific type of quartz ?
  • Is there a method for determining the specific frequency of each natural quartz crystal where its response (negative amplified voltage pulses) is the highest ?

Thank you for sharing your experiment !

Regards,

Fighter

Hi fighter
The scenario you have worked out is very correct. It took me patience and a few days to find a surface that would correspond to the two virtual poles + and -. It has to be understood that the internal structure of the quartz is fundamentally different from what we can understand, if we have not studied this chapter before
To summarize... a quartz chip has in view a hexagonal prism shape, and cutting it, for example to manufacture crystals for different frequencies, is not done according to the hexagonal surfaces. 
So for this reason many of the small pieces have to be sampled until a roughly suitable position can be found for inserting it into a circuit.

For the pointed questions you asked me:
1. If it is a natural crystal - yes it should work
2. As far as I know, I don't think there is a method to determine the exact frequency at amateur level.  The only way is to roughly determine the position of the poles and bombard it with a wide spectrum of frequencies varying the duty cycle until it responds.
Be careful with oscilloscope sensitivity!  It should be used on 20 or 50V - 1x scale to avoid errors.

Have a nice day everyone!

Hi, I think you might like this if you are into crystals. A very good document, like all army documents from that time.. Straight to the point, everything very clearly and comprehensibly explained. I recommend!!

Perhaps this is the same effect used by Piezoelectric Transformers. I found a few of them on some PCBs. I haven't tried anything with them yet.

Thanks Abit. 
I'm not a quartz crystal enthusiast, just reading up.  
As for the video it is very much for me!!! I know a little about this mineral, but what I saw in the video with your kindness, is beyond an amateur's possibilities. Regarding transformers ... To me they're cosmetic issues for efficiency, I think at first glance.
Very nice of you. realco....

Here is an informative comparison of magnetic vs crystal transformers by Texas Instruments:

Comparing magnetic and piezoelectric transformer approaches in CCFL applications

It also describes "a circuit used to control a piezo-electric transformer in a resonant push-pull topology".

That's true, but I said in a post above that we are amateurs. That's why we hang around the forums.I personally believe that there are still things in our swath that need to be discovered without such high end technologies where we can't get to, or at least I do. 
Have a peaceful day or night everyone.       realco...

That's another reason why I love these documentaries. When you see it, those people were able to do incredible things with completely primitive technology, from today's point of view, of course.. Most of the hi-tech tools of that time can be assembled by people today in a garage with things from AliExpress or trash. Today, even an amateur can experiment with properly scientific things, or how to say it.. It just requires knowledge and great skills with measuring and interpreting data.

Hi every body
 Lest you think I haven't already had an approach involving piezo elements in a transformer... Look! Obviously still at the sample level. Nothing spectacular !
