reverandkilljoy must be meaning time constants

@Sulaiman

Stan's Vic does not have a steel core, it has a ferrite core material and the vic produces frequencies in the AM range.

I hope that is the case.

So would something like this be suitable?

Good for 10Khz looks like to me. Talk to you more about the AL value when we talk again on skype.

Thanks Matt for the older Excel file....looks Great, kinda works for me but than crashed on my very old version of Excell...I will find a newer version.

I think Sulaiman missed a very important fact with the VIC.
If I am correct this is the first mono directional LC circuit I have ever seen.
I could be wrong?

PS: Matt I have a very large core A=94 B=76 C=30 E=37 when I stuck a bobbin on it the inductaince was... Huge!... I don't think we can use it...If you want it I will sell it for cheap.
Take care

Thanks so much Ronnie for the explanation on impedance matching .i did not get it entirely but i re read the grobs chapter on that isue.
I see you guys have all bunch of cores but dont want to gather for 1500 pieces order...its a bargin for 1$a piece.i would take 10 cores without thinking.

I would too, but only if I'm convinced no other off-the-shelf-cores will work.  I'm starting from zero here pretty much, unlike many of you guys and I'd really like to see this whole thing workable with parts anyone can get.  If we get painted into a corner where there are parts you can't buy or make yourself, that lets a lot of people out of this deal and makes it very difficult to actually share the technology.

I'm glad you can at least see it and play with it a little now.

I used some VB code and macros to kick-off the goal seek and calculate perimeters.  BTW, I never knew calculating the circumference of an oval or ellipse was so difficult.  I used oval shaped bobbins so they would fit on the cores, but keeping track of the wire length so I knew the exact ohms per turn was a real bearcat.  That's some code you guys should probably hang on to if you ever need to make those calculations in the future, especially if you don't know what a gamma function is.

Apparently no one is checking my work. Made a goof on the spreadsheets.

Please download them again and delete the ones you have.

I thought we already went through this and the GPS twin core was the way to go?
Oh found 1 more large core on the shelf...88x94 core =16mm

I do not know if it helps but as there are deliberate significant air gaps, you can use ferrite blocks glued together.
I have built several inductors and flyback transformers this way.

Blocks give some geomety options
and for bulk purchase, 100 pieces = 50 x 'C' core transformers or 16 x 'block' transformers

Question for today:
As the dielectric changes in the cell from water to gas, Does the cell capacitance change?
Everyone please chime in.

That's easy...
Tap water sucks as a dielectric so untill the water is mostly gone you don't have a dielectric.

It should do, water has a relative permitivity of about 80, so capacitance with water should be 80x capacitance with air.

I have made electrolysis cells with distilled water ... very quickly (seconds to minutes) the water becomes quite conductive due to ions from the metal electrodes,
as a first approximation, the conductivity of distilled:tap:sea water is 1:1,000:1,000,000
so measuring the cell capacitance with water may not be simple due to the conductivity of the water.

Stan used Tap water

My guess is that the capacitance decreases the more gas there is in the cell.

Matt buying an of the shelf core means that you have to redesign the whole vic from scratch.Using Stans core you have the advantage to use his coils and cell parameters

dont forget the famous statement. KISS

Stan once said that he wanted everything to be made from parts at the local hardware store. ( he stated this in a video )

now some times prototypes you cant do that, but i feel that there is a way to make it with off the shelf parts. thats the only way of mass reproduction.  this is the entire KISS method.

my 2 cents

Yes, It will,

if i set the values for the distance of the plates and the area of the plates and do not change theses....

water has a dielectric constant of 80.10

lets say we have water the cell, will be n value, lets say its 7.092054F

if we change dielectric constant to 1 ( for lets say air) we get a capacitance of  0.08854F

so indeed the capacitance will change. it will be come lower with more gas in the cell, i do not expect it to become the full value of air / H2,O2 mixture.  i believe it will be be only change some amount, there will still be water paths between the bubbles.

between the bubbles, this is where the water will become highly polarized, hence the " bubbles come from the center of the cell, not at the plates"

this i have seen.

Come on guy's weight in on the question of the day.s

Thanks Russ, I'm about to explain something about this, and I needed some people that has done some real testing.

hows this for real testing :

~Russ

more about that here:
http://open-source-energy.org/?topic=188.0

done get detracted by it, just thought if people missed it it is there.

just a proof of conspet to generate HV, Gas, and using almost no input...

although that is a simple form... the complete VIC is needed to take this to the next Step.

it might even use different principles that that of what Ronnie is explaining. so like i say, done get distracted ...

~Russ

Russ i know what you are saying...but i'l give you a practical example of using tv flyback cores.With those flyback cores i get inductances of 10H to 13H.To get stans values you have to have a very big distance between the cores,so big that you loose almost all the mutual coupling so its not that KISS
