My Inkscape script again, for these who have analog oscilloscopes. So that it will not disappear. In fact the CSV that the digital oscilloscope outputs, is time and voltage, and a separate CSV for both channels? So properly it should generate CSV the way the oscilloscope outputs, and then the calculation script should input that. But i don't know exactly what the format is, so by now it's just a list of voltages. So one may have to use a spreadsheet or an online converter, to convert CSV to list. Someone show me a single example of the CSV that oscilloscope outputs, as i couldn't find a single one, that should be enough to rewrite both scripts to using exactly that CSV. Thanks.

When the signal is sine then phi is enough to see overunity, right. Showing the multiplication of the current and voltage on the coil shows overunity as well. But it may not always be exactly sine, and in all cases calculation is likely necessary to finally calculate and confirm the input and output power.

Zero power factor, i guess it is when the average power is near zero, right? It may look like that zero power is not very important for overunity. But this is exactly what we are after. When average power is zero, then positive and negative powers are equal. The best i think we can dream of is when the negative power is slightly greater than the positive power, and this shows as a near zero average power.

Many thanks. The format is even simpler than i thought. Tektronix has a great precision, 1000 units in the time scale, that's huge. I see it can output math channel, which makes the calculation very simple, but not all scopes can do that and i make it generic.

For analog scopes there has to be both channels drawn in Inkscape. The way that the path for channel 1 is drawn first and the path for channel 2 is drawn second. It doesn't matter where these paths are located on the drawing, it only matters that the channel 1 path is first and channel 2 path is second. The x length of both also has to be more or less the same, the shorter of these determines the length of CSV list.

Takes some time to figure out. Nothing complicated at all, but the usual stuff about what is where.

It is said "The inductance generated by the capacitor in circuit 1 would generate Current in the coil of wire in circuit 2 indirectly". By the virtue of the Holy Spirit?!

There is no magnetic coupling between circuits 1 and 2 because they do not share a magnetic flux (they are transverse). There is a capacitive coupling but no current because once an electron has been attracted to a capacitor plate, there is no longer any reason for it to move, we are in DC. When the electron "e" is capacitively attracted to point "A" (see drawing), another electron from circuit 2, on the other side of the coil, is attracted in opposition to the other end of the coil. The resulting effect for a current is nil.
To induce a current in a coil inside a capacitor, or from the coil to the capacitor, the axis of the coil must be perpendicular to the capacitor plates and the current must be AC. We face a childish crackpot who mixes capacitive and magnetic coupling without understanding either one.

Partzman, BTW, your data is about what? It gave the results, input power 5.6 W, output power 23.4 W, looks like overunity, or what is it? I calculated assuming the circuit, coil and resistor in series, and that the resistor was 47 ohms, if it differs, then the results may not have any meaning.

Interesting posts.

Words and numbers are just words and numbers until they induce a thought or idea at which point they become something else. I often wonder why so many have such a limited perspective of electrodynamics... why limit it?. We could just as easily say an Emf is a signal, a current a transmission and any dissipative circuit elements a receiver. We should also note that as many have said in the past, we can take mechanical and electric analogies literally.

That is we know a particle cannot act on another particle directly but only through a field indirectly. Thus every force including an Emf must constitute a transmission of energy by way of a field. Unfortunately many ignore the field or delegate it to some unimportant spooky action at a distance.

In the past I also looked at the notion of electro-magnetic phenomena as a signal transmission which conveys information through fields from a computational perspective. Assigning the equivalent of logic gate functions to all the discrete phenomena we see in electrodynamics. For example Lenz Law is a NOT gate or inverter with respect to an induced magnetic field change. An XNOR logic gate translates to field coupling and whether an external field is present and can act on something or not. So we build truth tables to represent all the electro-magnetic functions and at some point we find the electro-dynamic realities we know can be represented by form of software. All one has to do is look at the humble beginnings of the logic gate and how far we have taken it in computing to see the potential.

When we start looking at the big picture from many other alternate perspectives we can often learn many new things. Who could have predicted that a simple logic function in punch cards could have created the automated world we know today let alone Artificial Intelligence. It is very strange isn't it?. It begs the question... if AI which may soon surpass our understanding of things was born from the simple relationship between patterns of "1's" and a "0's" then how far can we take electro-dynamics?.

The trick, I have found, is not to get too bogged down by underachievers or those with business interests. Do your own thing, have some fun with it, imagine the possibilities. Our goal was never to lower ourselves to that level but to rise above it and we cannot take them with us. limited seating capacity...

Onepower, what is a field? Space is a grid, in the grid, the nodes cannot interact directly. The way to do it, is to send quanta, that way one particle "finds" another. You may call it digital, it's not a computer though, the matter is that it's a grid. But it's certainly discrete.

What is the Lenz law, it's that everything causes an opposite reaction. And it's because everything protects its integrity. Like you step on the rake, it hits you, it's because rake maintains its integrity.

Again the first point of both paths determines their x axis and the beginning of the x axis for both paths. And it doesn't matter at all where these paths are drawn or what is their location relative to each other. It only matters that channel 1 path is drawn first and channel 2 path is drawn second.

Those test results were taken from a voltage driven T225-26B powdered iron toroid with a bifilar litz winding.  The Math channel indicated the energy in one of the windings over time and the "Inductance" was calculated in Excel.  The second bilfilar winding had one end connected to ground with the correct dot polarity that allowed the first winding to discharge it's energy thru the distributed capacitance between said windings producing the voltage waveform in CH2(blu).  There was no additional resistance other than the wiring, mosfet switching loss, and coil resistance of 1.15 ohms.

Other thing, next() now returns 0 when there was no number. This enables to get all values, like the following calculates your energy per cycle. It's in J if your instantaneous power was in W. I don't know the frequency to calculate power. Your instantaneous power was always positive, why?

It may look strange, but it's the right way to overcome what is missing in Python, and make it straightforward. Using list with an element string Instead of string, makes it modifiable by function. Inkscape script and its trinket.

Not really the topic here, but there are ways in Inkscape to convert oscilloscope traces to path, by not copying the path from the image completely by hand. I'm no expert in Inkscape, so the Inkscape experts forgive me, i can only tell the little that i know, please share your knowledge if you know some great things.

As much as i know, there is no way to convert a trace into a single line path automatically. If one knows any way to do that, please say, maybe there are some tools other than Inkscape that can do that.

In the Inkscape Path menu there is an item "Trace Bitmap". This and the "Stroke to Path" from the same menu, enable to convert traces into a circular paths. These will not be lines, they have some thickness.

At the right edge of the Inkscape screen there are buttons to select different modes of snapping. One is "Snap to paths". One can draw a zigzag path inside the circular path of the trace, so that the ends of the segments will be on that circular path. The other snap mode is "Snap from and to midpoints of line segments". This enables to draw path through the midpoints of the segments of that zigzag path.

This path will be a calculated approximation of the trace by a single path. This is not hand copied, but transformed from the original image. It may be too complicated though. There still has to be snapping to grid, and also considering all kind of imperfections of the image, a path copied by hand may much better match the trace than this semi-automatic transformation. But just to let everyone know, that there is such option.

A line from the beginning of the x axis may be drawn later. At the left side click on "Edit paths by nodes". Holding down the shift key, select the paths and the line segments to be joined. Then "Join selected nodes" at the upper edge of the screen, joins the paths into a single path.

Btw, what one thinks about the circuit on the figure below? What happens there, when the pulse is on, and after the pulse ends? Can one simulate it in any way? The caveat there is that these are not two separate coils, the two parallel lines indicate that these two coils are on the same core, so they cannot be simulated as two separate coils. That is to understand, what the capacitance between the windings really does.

This can be simulated with python, or c if one likes, if there is no existing simulator that can simulate this. Something like, solenoid  phi = mu0 * mur * n * i * a / l , what about toroid? The current is split, part goes to the left coil and part to the capacitor, magnetic flux is however the sum of the magnetic flux that both coil segments generate. Faraday's law of induction  e = - dphi / dt , which is voltage on the coil segment. Capacitor  i = c * dv / dt . One should start from induction, because this is the engine of change.

No, unity is not written into these equations, if there is unity or overunity, then it supposed to come from applying these equations.

Interesting? This question usually means, who will now do the dirty work. Why should i do?
