Could i use this hardware as a signal/frequency generator ?

http://maplin.co.uk/Module.aspx?ModuleNo=220045


Thanks.

@Deepcut

Its frequency range looks proper. You are going to need a voltage divider
"level control" potentiometer. The output signals may be zero to +5vdc. If you need +/-2.5Vpp use a 2uf or larger non-electrolytic dc blocking cap in series with it's output. In a signal generator the signal will always be +/-centered about ground. The transistor side injects it's own dc bias onto
the signal.

@gotoluc

Are you tempted to add two thicker coils of a few turns each over the existing coils. This way you can measure any output on them while in resonance compared to slightly off resonance. You can do the same to your one wind coil and compare output results. If both are the same output, then we can scratch our heads even more. One would assume that more inductance means more field but does it mean more output.

That is a good idea wattsup ;)... the only thing with that is at frequencies the two coils may to resonate on harmonics and give a higher output which may not be a true linear output test.

I always liked the idea Magluvin had to wind an output coil at 90 degrees of the pulsed coil. This shows more the return flux energy since it can only picks up when the main coil is switched off since the cores magnetic flux does not care of the angle the pickup coil wire is at.

@Luc,

I think we need to make it an asymmetric system, or drive it into a parametric resonance state.  We're already working on the non-linear MH curve by placing the magnet on the toroid, so I don't think we need to worry about this, other than finding the best position.  Maybe the dual coil is, or could be used to create an asymmetric system with very little modification of the circuit.

Thanks GB for bringing this point in.

I also agree! if it has value it could be done without too much difficulty.

Thanks for sharing this.

Yes, the introduction of a second signal into the resonating circuit is key.  Here is a link to a video(rather old) that mentions exactly that.  He is talking about a solid state N-Machine http://www.youtube.com/watch?v=X0L9rq87n3w#t=5m20s

Most intriguing that ssOrbo is also a multi frequency device.  Can it really be this simple?  Sure hope so, either way 2010 is shaping up as a banner year for OU research.

Thanks redninja for sharing this video.

I wonder what he is talking about that it is front page new in India that they will be energy independent?  anyone here know what he is referring to?

Hi djeri,

thanks for your post :)

Many of us here are aware of Jean-Louis Naudin experiments.

Please note that this is not free energy as he is putting in the main coil much more current then he is getting out. I do agree with Jean-Louis Naudin that the energy picked up by the secondary coil is from the return flux of the permanent magnets to the core.

Back in January I made this video: http://www.youtube.com/watch?v=Y3_vr8VIdpE

It's a replication of user Magluvin's ferrite core toroid with primary and secondary coil that are wound at 90 degrees of each other. Once the primary coil is shut off the permanent magnet flux returns to the core and this is what is picked up by the secondary coil. I saw that back then, so it is not new to me what JLN is doing now.

One of the many differences here is, we are bringing the main coil to resonance, which makes it much more efficient in current it uses.

From my best test to date the main coil can resonating at 12 KHz and feed its own pulse circuit at the same time and only use about 10 mirco Amps at 3vdc.

I do not know of any pulse circuit in the world that can just operate the gate let alone the main coil of a IRF640 mosfet with this low a current using 3vdc at 12KHz. If someone knows of one please post the circuit and the factual test data.

We are far from our goal but I am hopeful we can find ways we can further increase the input voltage without increasing the current too much and maybe we can get some usable current from the device.

Hopefully with more development we may get it to produce more current out then what is going in. That is the goal.

At this time, this is the main difference between what we are doing here and Jean-Louis Naudin research work.

Gotoluc,

I am trying to calculate the number of turns on your core given the inductance. To do this accurately I need some more information about the core parameters. The turns can be given by this equation:

N = number of turns
Al = nominal inductance
L = inductance of toroid in mH

N = 1000*sqrt(L/Al)

When I calculate this with a core of mine that that has inductance of your core (1050 mH) has permeability=850 and Al = 1000 I get 1026 turns. Can you give some more details about your core like the dimensions, permeability, and most importantly nominal inductance. The Al is almost always given when you buy a core.

I am excited about this because it may be the first public motionless research platform for ferroresonance. Having a motionless device to study is important because it allows us to reduce the variables that have been stopping all of us from isolating this phenomenon.

Thanks,
Chad.

Hi Chad,

thanks for your interest. I calculate a total of around 800 turns or less are on the dual coil Toroid.

To make one turn of wire around these ferrite cores using the AWG 30 or 0.27mm wire used to make this toroid coil takes 35mm of wire length (on first layer) for each turn.

I have no information on the ferrite cores as they were a lot purchase (different sizes) on ebay with no details.

Hope the above help you to find the core specs.

Gotoluc,

Based on the information you gave me I was able to estimate the core permeability.

L=1050 (inductance in mH)
cw=3.5 (circumference of winding in cm)
N=800 (number of turns)
le=7.2 (my estimate of average circumference of toroid in cm)

Ae=((cw)^2)/(4*pi)=0.975 (area of toroid cross section in cm^2)
Al=(L*10^6)/(N^2)=1641 (nominal inductance L in mH)

finally...
permeability=(Al*le)/(4*pi*Ae)=967

The accuracy of this depends largely on the accuracy of the input values that are just approximations. Considering the permeability and appearance of your toroid I am guessing it is a NiZn ferrite.

I have wound quite a few cores in my time and know how hard it is. I cringe at the thought of winding 800 turns. There are machines that can quickly wind toroids and with this information you can place an order with a winding company (that's what I am doing).

Thanks,
Chad.

Hi Chad and Luc,

Recently I have come across a very good (and freeware) software on calculating toroidal coils inductances for any core. See here the mini Ring Core Calculator 1.2:

http://www.dl5swb.de/html/software_for_amateur_radio.htm

It can be used not only for known cores (where you know AL or u permeability but for complitely unknown cores.  But this latter requires the unknown cores outside OD inside ID and height sizes and also a certain number of test turns what you can measure with your inductance meter.
Then the software uses these data in its Tools feature to calculate the relationship between AL and u permeability and imports that for further calculations.  A very useful program.

So if Luc posts the OD, ID and height for the toroidal cores in question we can learn the core permeability pretty precisely. (MAybe Luc already posted the core sizes I have no time to wade through the thread.)

rgds,  Gyula

Thanks Chad for calculating the core permeability.

They most likely have a permeability of 1000 seeing your result.

I picked up a digital caliper and here are the exact measurements of the core.  Opening diameter 0.814" or 20.67mm Outside diameter 1.358" or 34.5mm Maximum height point is 0.465" or 11.82mm Minimum height of rounded sides is 0.375" or 9.53mm Width is 0.27" or 6.87mm

Thanks for sharing

Thanks Gyula for the link to this toroid calculator software.

The core size is in the circuit diagram but I just picked up a digital caliper and here are the accurate measurements.

Opening diameter 0.814" or 20.67mm Outside diameter 1.358" or 34.5mm Maximum height point is 0.465" or 11.82mm Minimum height of rounded sides is 0.375" or 9.53mm Width is 0.27" or 6.87mm

Thank you Luc, and please one more data: a single layer of (any) number of turns gives ? uH or mH,  I know somewhere it could be found too... :)

Thanks, Gyula
