Russ,

Recieved my core and bobbins today!

Once I get it all together and the circuit working I am going to perform many tests on the coils before I connect to the cell. I will report my findings and tests and explain why I did them.

Thanks and blessings to all!

Interesting.  It looks like the LCR you have is this one also goes under the
brand name of NEWCASON and a different model of XC4070L

 http://www.dealexcel.com/lcr-rcl-inductance-resistance-capacitance-meter-4070l-sku647_p647.html

 For $20.00 not bad, but it is a Chinese Shenzhen special. It's sold all over the internet but the original manufacture is hard to find.  Here is the best I can do for instructions, if it's the same unit.  

EDIT (6/7/2012):

NOTICE:

I need to make clear that this data from testing the VIC circuit is inconclusive. It is experimental/informal data and is not final data. Other testing methodologies (not known and not done yet) need to be employed for more data to be available until arriving at a conclusion. All this data is neither good nor bad data.


I have seen that there may have been objections to the testing methodology I have used to arrive at this data. If the testing methodology I have used is not good enough, please prove it.


DEFINITION:

testing methodology (or test method) - strategy or method that produces data or a result.



Here's an addendum to the inductance measurements with a scope shot:

This was an attempt to get a maximum peak voltage from the 1200 permeability cores with the VIC circuit. Other circuits need to be tried (i.e, a standard or gated frequency generator).

• Power consumption was 12 volts at 600 milliamps with a hot primary coil.

• Voltage peak was up to about 15 volts.

• Probe leads were wired across both choke coils.

Im about half way done with the VIC box sketchup.  Need to start the cover next.



I'm 99% sure on most of the measurements.  The measurements in the Z axis are hard to pull from the photos.  All the important measurments are good though.

Nate

Started testing coils tonight. I'm taking measurements and making calculations before I try connecting to the cell.

I have been testing coils individually with the core inserted and bolted down. Resonance of each coil has been found. Interesting to note that the L2 Choke (directly across from the primary coil) has a resonance which is several orders greater than the other secondary coils.

The testing continues.

Coil Specs:

Primary
34.2mH, 12.5 Ohms
Feedback
28.7mH, 13.2 Ohms
Secondary
1.038H, 77.4 Ohms

I still have to start the cover, my "day" job keeps eating up my "OS" job time! lol  Might have time tomorrow.:cool:  I will eventually add the wire fittings too, still looking for something that fits the 2 hole pattern inside of the box.  I'm thinking of some kind of 2 screw terminal strip with mounting holes on each end.  Possibly a black plastic PCB style phillips screw terminal, I just cant find what im thinking of.  The holes are for 6-32 screws.

interesting, could you post your other test data also? like each self resonant, ect?

that is with the new core, yes?

cool! thanks for sharing! ~Russ

Yes all this info is with the 1200 permeability cores that we special ordered;)


Primary
34.2mH, 12.5 Ohms   Fres: 60.1 kHz
Feedback
28.7mH, 13.2 Ohms   Fres: 20kHz
Secondary
1.038H, 77.4 Ohms    Fres: 10.5 kHz
L1
.823H, 77.9 Ohms     Fres: 44kHz
L2
.820H, 76.5 Ohms     Fres: 13.5 kHz

I will test everything again tomorrow to confirm these numbers. I am also going to remove the core and test Fres of each coil. This is so I can calculate (estimate) the coils capacitance. From there I will make some calculations and try to understand more about why the coils are producing AC from a square wave signal.....

I will also connect the driver circuit soon so I can test with a unipolar square wave to see if the polarity is shifting. I believe that is one of the problems with getting this tech working.

and the data is in... man that's a lot of work! lol

Hi,

Looking good, we almost got the right values!!!

NOTE. You say the core MN67 is 1200 perm, but it is 1100 perm.
They changed the data-sheet a couple of times! (1200, 1100, 1250) http://www.cmi-ferrite.com/Materials/Datasheets/MnZn/MN67%20ISO%20WEB%20DATA.pdf

First posted here by me:
http://open-source-energy.org/?tid=170&pid=3704#pid3704

Thinking about the core material:
Now we use Mn-Zn FERRITE with 1100 perm.
Getting lower perm is changing from Mn-Zn FERRITE to Ni-Zn FERRITE.
Using lower than 1100 perm to get the measurements correct, take for example CN20 Ni-Zn FERRITE 925 perm. Or http://www.cmi-ferrite.com/Materials/Datasheets/NiZn/CMD10.pdf

Looking at temperature curve, perm is also not stable but lower than 1000 (-50 to 100 degrees Celsius)

Thoughts?

well we went from 2000 to 1100 and i'm thinking 900-800 or something...

i think we need to test these and try to find a company that can supply us with a smaller order!?!?

just some thoughts. lets test and see where we come up... i think we can make these work if there going to... these will show some signs of proof...

Hi,

Yes, test this core first. We can all learn a lot from this setup... ! :cool:
(Waiting on the core etc.) :)

Br,
Webmug

I have been looking at ferrite 43 for some time.
It has an initial Iu of 850.
More research has to be done before purchasing the material though.

I think this coil is really going to be a challenge to get working properly.

In the mean time I hope all will share their findings so we can have a clearer understanding of the circuit.

The more that is discussed and shared, the more we will learn.

I found out what the name is for the terminal strips I was thinking of.  "barrier terminals"  I think this may be what stan used inside the box to the splice the high voltage wire to the coil:
http://www.molex.com/molex/products/datasheet.jsp?part=active/0387007312_TERMINAL_BLOCKS.xml

The hole spacing is very close and the barriers between the terminals makes sense for blocking arcs.

I still have to start the cover, my "day" job keeps eating up my "OS" job time! lol  Might have time tomorrow.:cool:  I will eventually add the wire fittings too, still looking for something that fits the 2 hole pattern inside of the box.  I'm thinking of some kind of 2 screw terminal strip with mounting holes on each end.  Possibly a black plastic PCB style phillips screw terminal, I just cant find what im thinking of.  The holes are for 6-32 screws.

I found out what the name is for the terminal strips I was thinking of.  "barrier terminals"  I think this may be what stan used inside the box to the splice the high voltage wire to the coil:

The hole spacing is very close and the barriers between the terminals makes sense for blocking arcs.  

Nate

I have some of these.:D

OK

I have calculated more on the 5 coil VIC I have constructed:

Each coil has a very narrow bandwidth and a high Q factor. What this may mean is that these coils will act as bandpass filters. A square wave can be Fourier decomposed into an infinite number of sine waves at different amplitudes. When you try to pass a square wave through a bandpass filter the filter will only allow certain frequencies to pass through it. What this means is that the square wave will not pass through the coils and the result would be a number of different possible waveforms at the capacitor which will change with frequency. The bandwidth can be increased by adding resistance internally to the coil (higher resistance coil).

I am not sure if the high Q coils will have much of an effect on the overall circuit at the resonant freq, more testing will follow.

Primary Q 1033 Bandwidth 58
Feedback Q 273 Bandwidth 73
Secondary Q 884 Bandwidth 11
Choke L1 Q 2917 Bandwidth 15
Choke 2 Q 911 Bandwidth 14

Also, I am thinking the capacitance of the secondary is coupling to the L1 Choke and the smaller capacitance primary coil is coupling to the L2 choke which may be why it has such a high resonant frequency when compared to the other coils. I still wonder if there was a glitch or I made a mistake with that coil, but after several tries the Fres remained at 44kHz.

I have been looking at ferrite 43 for some time.
It has an initial Iu of 850.
More research has to be done before purchasing the material though.

I think this coil is really going to be a challenge to get working properly.

In the mean time I hope all will share their findings so we can have a clearer understanding of the circuit.

The more that is discussed and shared, the more we will learn.

I agree with all you are saying here!

Guys,I want to place an order for cooper wire for the vic bobins,can you tell me the diameter in mm because there are many gauge tables and verry confusing,from the pics I think is 0,35..waiting for reply,Br

It's 30awg heavy insulated wire which is about .0113- .0115' with the coating. Bare 30awg is .0099- .0100".
Convert to mm and you get .251-.254mm bare.
With the coating you should be around .269-.302mm.

Be sure you get the heavy coating, not the single build.

Hi Jeff,
Firmware is for ATmega644P, this version wouldn't work for a ATmega328p controller. But if you can find/make software for ATMEGA running a Pololu A4988 Stepper Driver, let me know. Got also a ATmega328p board.
But I needed a "simple" DIY winder configuration so a got this as a result. Can be much simpler :D without the RepRap functions embedded in the firmware etc. :D

I wonder if floaty boaty could help with this, he is really good with software. He could possibly even just write a program to control the speed and count the turns [opto] as it's winding, maybe even run a display for speed and count. To do the count we could use one end of the square bobbin to pass through the opto as it turns, make the opto adjustable for different size bobbins, as well, that would really be cool.:D:cool::P

No problem.  Looking into it now.  :D

Thanks Johnathan:D

Small note: "Jonathan" not "Johnathan". :P

So here it is.  Sorry for the wait - learning all about stepper motors and what-not at the same time, plus that ecs for Russ's hho engine test (how's that going?  it could be used for the WFC project as well).

Simple configuration: one motor to spin the spindle, and one stepper to feed the wire; no stepper driver needed (maybe relays).  Check the "config.h" for configuration.

Cool.  Let me know if you have any questions about any of code.

Thanks HMS-776 ,I see ,I was confused because 30awg looks very thin and in the pics looks much thicker,I even measured the picture wire with a measuring tool and give me 0,35, 0,33...
Ah,and one more thing look at one of the pics where the wires ends  are hanging ,look at the solder end,looks to me that is no special insulation ,and is still 0,35...I may be wrong..

The sizes I said before are all right. I got them off of the MWSwire.com
They are in inches but that's easy to convert.
