I`v built this VIC and hope to have close measurments to the actual measurments provided by Dynadon.
I used awg30 because I had difficulty finding awg29 to ship to my country.
primary 650turns
secondary 3500turns
choke L1 3500turns
choke L2 3500turns
I`ll take resistance and inductance measurments later today

Interesting measurments!
spot on!
-
As for the primay i`m getting 12.7ohms and 46mH
and for the other three coils i`m getting around 90ohms and 1.26H~1.35H
Considering that i`m using slightly thinner wire (with some more resistance per the length used) those numbers make sense and look pretty close to stans.
primary 12.7ohms vs meyers 10.5ohms
secondary and chokes 90ohms vs meyers 75ohms

Hi hydrogenmask,
Good work!
For actual measurements close to SM VIC. :)
Do you know the frequency of the meter used for the readings?

Nice vic! I hope you post your results.
What perm is your core?

Dont have an idea as for the frequency use by the meter to measure inductance. But check it out with another meter and measurments are aproximatly the same.

Tested this setup yesterday.
Using a 2mm gap 3" insulated tube cell
Pulsed the primary with a 50%dutycycle squarewave from about 200hz to 20khz.
found 2 sweet spots were the VIC resonated that were @ about 4.5khz and 14khz.
However unfortunately there were no phase shift as I was especting :( i.e. voltage sinewaves were same in amplitude and in phase at the +ve and -ve terminals, and therefore no substential potential difference across the cell.
What I`v learn from these 3 experemnts is that
1/ water in between the electrodes should be totaly isolated from ground.
2/ earth ground connected to SM isolated ground seem to help in achieving VIC resonance better.
Still disappointed with the results so far ???

Thanks for sharing!
We known the feeling of disappointements, HM!
1000 tests with 999 failures....
Hangin there.

Hi HM,
How did you build your wfc? Is it insulated in delrin? Any photo's you want to share of your setup?
yes, lots of questions we have... 8)

Hi Webmug.
Yes, my test setup consists of 4 different cells and experiments were done to each one individually for diffirent capacitance value purposes. Cells were encased in pvc and it was designed so that water can circulate through in between the exitors.
the 4 cell specs are:
1) 6" long 2mm gap
2) 3" long 2mm gap
3) 6" long 1mm gap
4) 3" long 1mm gap
I can show you some pics of the construction but maybe i will create a new thread

Wow nice test cell! have you thought about machining one to Stan's specs?

Yes that is the next step. I`v built 3 VICs and now the task is to match them to a cell. What I intend is to built twelve 3" insulated cells and by connecting them in series/parallel while experimenting there might be a matched combination between the VIC and wfc.

After spending some time with this VIC I managed to get the 180deg phaseshift without the cell connected. The negative choke should be flipped. You cannot just flip the terminals, you must iether wind the choke the other way round if the chokes bobbin is one piece or if bobbins are seperate you can revolve the -ve choke. This is the only way to achive symetrical waves. In the clip below I`m getting resonace at 12.5khz. and as the cell is connected the signal is killed.

Hey Lads thanks for all the good work and experimenting you all do it is appreciated as im sure there are others like me who at the moment dont yet have the resources available to experiment like you do.
a thought crossed my mind. Reflecting back to the sonic heater (in nz many years ago) where the inventor tuned 2 bell shaped pieces of metal to each other using music tunes to tell the sound of each and as a pair, formed a crucial part to their equation of having their device working when they applied both a voltage that had a waveform to it.
might there be a possibility for both wfc cells and water heater devices may require a tuned set/pair of electrodes to function in tune with the vic/chokes and the waveform/voltages applied to them...?
cheers

Hi, hydrogenmask. I want to ask you about the cell resistance. Because mainly that value shunts out all the resonance phenomena before anything happens. This of course depends on the water type used.

I`m using distilled at the moment.
