Tesla Bifilar Style Chokes - Interesting Result
« on: February 25, 2013, 04:29:03 am »
Today I hooked up 2 Tesla style bifilar chokes in my circuit as shown in the attached diagram.  At the moment I connected them to my plastic covered test cell my oscilloscope showed an oscillation between them and my cell ranging between 13.6kHz and 14.4kHz before I turned the power on.  The RMS voltage showed at 335mV and peaks P-P up to 500mV.

I turned on the driving circuit trying to tune into the same frequency.  At one point it locked into resonance at a mich lower frequency, but interestingly I had 2 different frequencies on the different leads to the cell!  The one was at 900Hz and the other was at 350Hz (both approximate).

I was able to duplicate the off oscillation twice, but I then contaminated the water I was using and lost the self oscillation.  I'm not entirely sure how to duplicate it again.  The original water was rain water that the cell had been sitting in for a couple weeks.

I have also attached an image of the tesla bifilars I am using as chokes.

Ok, TS.

The roles of the wfc and the bifilar coil are as follows:
Coil = induction
Coil = capacitor
WFC = resistor

Meaning, you get a RLC resonance circuit.
If one of the compents change, so does your resonance frequency.

You probably all knew this stuff....

timeshell, Very interesting results you have demonstrated here. The coils the most interest to me. They seem to be wound inside of a cd case, maybe ? How did you arrive at the exact number of turns or did you fit what you could inside the case you used ?  I am working on a large cell of a different type myself and have been looking at other coil designs to play around with. Any thing else you can tell us ?

Yes, I wound the coil inside a CD case. I didn't choose any defined number of windings, just wound for the capacity of the case.  I used double side carpet tape to get it to stick to the case during winding.  Not the most effective way, but did the job for a quick coil.

I'm afraid I don't have much more to report at the moment on this coil set.  My attention at the moment revolves on the concepts of electrolytic capacitors and how the "excitor array" (in my opinion) may be an exotic sort of electrolytic capacitor.

I'm very proud of your creativity! I have not seen anything like what you're doing. This is nice stuff.

13.5 MHz I think water was at, Google it to confirm. You got Khz, I think it was MHz, I forgot.
