@Grummage and @all
This post is relative to your thread entitled Re: Akula0083 30 Watt Self Running Generator located here.....
http://www.overunity.com/14378/akula0083-30-watt-self-running-generatorYou look at past works and how they are portrayed and this will give you a basis for present work from Akula. He has always drawn his coils as they are. If that E-core had anything else but one wind left and another wind right, I am so sure Akula would have drawn it in his circuit just to save a million questions from potential replicators, so I am convinced the @T1000 coil wind method is not right. Just follow the diagram as it is shown.
Also, doubling the frequency means nothing . The flux path of the E core will not react in a greater way. You are simply making double the frequency most likely this is cutting the amplitude in half because you are creating cancellation points from both sides of the center core. Doubling the frequency means you have half the time to produce the same voltage rise but if that rise is not twice the intensity your voltage will drop from its original point to half. Pulse frequency and amplitude is everything. The higher the frequency, the less time you have to produce the same spike. That's why if the amplitude does not increase as the frequency increases, the waveform will drop. Also in almost all coils with a core, you will hear a squealing sound anywhere between 150 and 6000 hertz but this does not mean you are at a sweet spot.
What I think is you are mistaking how Akula winds his air core towers and how he winds his transformers. You can wind air cores in a million ways and always expect an effect once you find that sympathetic frequency. But with a core, there is no million ways. The flux, its limitations to augment on pulse and then to try and reset or return to neutral bias on off pulse all come into play. The core needs to be told to swing one way, then it also has to be told to swing the other way. It does not just revert back like a spring. Air cores do not work in the same way at all.
Why do you think Tesla was so happy when he invented AC. At last he had both a positive and a negative signal alternating so his core would not only be pulsing but undergoing a forced rebiasing at the same time. Less heat more action. Unfortunately I am sure Tesla was not 100% happy because like DC, his AC is only active on one side of the coil since the other side always stays neutral and the side receiving the AC swing is happening gradually, sloping up then sloping down. For coils, there is better then AC and DC but that could be discussed on another day. hehehe
No matter what Akulas' device does more special then others, it has to involve alternating a north and a south field in proximity of a secondary. But DC starts at 0, not at any minus voltage. So how can it rebias the core and the atoms in the copper to get them fully ready for the next pulse. That is the Achilles heel of our DC coils is getting the flux in, then out, to have clear path again for the next in. If the out is not complete, then the core cannot create a maximum flux change and your secondary will only feel the lazy changes and not the extreme changes plus the core will heat up.
I think the copper strip is used to do that. You put in a pulse and when it is off, the copper strip may help sink out the flux as fast as possible so the next on pulse has a clear slate to once again re-energize the core.
For the normal EEer designing devices for our normal daily use, yes they have concern of energy consumption but their concerns are not the same as ours. Where they look to destroy havoc, we look to take advantage of it. Where they choke, we want to spike. Where they dampen, we want to increase.
I am including a link, located on my fpt OU web site, of a pdf on cores that I find is one of the best I have read. Lots of math but if you know how to read between the lines, you will understand more about the core. From this pdf, and the descriptions of the materials, I think the #18 will be the best as an overall performer but the top EEers here may have other opinions.
Another point.
Always remember that capacitors discharge when connected and inversely, inductors (coils) also discharge but only when disconnected. This means never disconnect the transformer while it is in operation because this could toast your circuit. Always wait till everything is turned off before disconnecting the main inductor. I have toasted one regular FG (16.5v at mA) plus one big FG (100v at 1 amp), power supplies, big powers supplies that prove this one fact. You get caught up in the moment, pull a wire and zapola, the FG or power supply is toast.
The other point is this. Your output is your only way of judging how well your unit is working. I will always use a capacitor with a diode on the output to let the output load the capacitor. Then if the energy increase is enough you can put an LED (one or more) across the cap with your volt meter as well. Now this is the best way to see how the output is performing and changing as you play with adjustments. But the output diode you will use is the most important part of your system because if you have the wrong one, it could give you 1 volt loading on the cap while the best diode can give you 20 volts loading under the same conditions.
Seems like this has not set into the minds of OU researchers yet, but I am always trying to push this as the most important part of your system. We work our asses off to produce output at which point most neglect the output diode choice. Just a crazy way to work. Just look at my youtube here for the umpteenth time;
https://www.youtube.com/watch?v=nj0ShZV6bhYIf this part of your R&D is just relying on one available diode, then you may as well just stop working in OU because chances are that the best results from your experiments will never be known or manifest. You look at a circuit diagram that has no model numbers. It says diode, so you take any diode, do the test and it does not work so you say "this test shows this circuit does not work". But that is not the case. It only shows that this diode does not work. You need to try a good 10 different diode models to make sure and I don't really care how experienced you are in EE or if you say "I'm using a fast acting diode". Now if you make any further changes on the circuit and redo the test, you will have to hunt again for that best output diode. Even if you find that the same diode is the best with the circuit changes, YOU STILL HAVE TO TRY THEM ALL TO MAKE SURE. That's how you learn and find new things. It is the methodical process of investigation that will help you learn the effects. Sometimes the smallest comparison can offer the greatest insight.
Also, at this stage when just pulsing a coil and checking output, you should not use a ready made bridge rectifier. You need to do as above. Once you find the right single diode, you can always make your own rectifier using four of the same. These ready made bridge rectifiers are good when you are working at 60 hz or when output efficiency is not a concern, but as soon as you start working at higher pulse frequencies, they are simply not worth relying on for true results unless you make a Diode Carousel with 10 different bridge rectifiers to find the best one. Hmmmmm.
I'll repeat. Most of our works involve making a set-up then hunting for the right frequency, but we then neglect to hunt for the right output diode. Once you have identified the right frequency because the scope waveform found a peak setting with any diode, you need to then hunt for the best diode at that point. Then you can work to make it in a stand alone circuit. Neglect the diode hunt and you are again working blind or at best working with a possible major handicap. It's like driving a car with low air in the tires. Well the car will roll but you are not going to win any awards.
If a circuit diagram shows a specific diode model, just know that this model is not identified just for fun and that any other diode may not necessarily work in its place. Diodes are as different in reaction times as there are different women on this planet. hehehe One is more or less finicky then the next and usually only one will be the "right" one for you. I pronounce you Man and diode. You may kiss the output. hahaha
Another point. You have a primary coil wound on a core. You now have two ends to the coil. One end is closest to the core or the first layer or let's now call it the Primary Core Layer (PCL) end and the other end is the farthest away from the core, Primary Outer Layer (POL). So you have this pulse system that produces your make/break. But which side of the primary do you want to make/brake is a very important consideration. Yes, you need to test pulsing from each side and compare results, but, technically, you're best side to produce your make/break at the Primary Core Layer. That will be the coil end that experiences the most change to happen nearest the core because the other side is always connected to the same unchanging signal.
I have come to realize that all coils suffer from what I call Half Coil Syndrome (HCS). (I believe that's why Tesla invented AC as a semi-solution). At best, only half the total wind is in active changing mode while the other half is the support half that just does not change as much. I will start covering these points when I continue my Understanding Overunity thread in the coming days. So consider this........When you have one primary, half is active but if you put two primaries in series, now one complete primary will be active because that complete primary is half of the total series primaries that the pulse will still consider as being one complete primary. So what will happen when your primary is totally active over a core? hehehe
Last last point. Many guys will pulse a coil and put their scope probe at one side of the coil and they see this waveform. Many think that this waveform is homogeneous across the full length of the coil so they think that is what's going on in the coil. Not so man. What you are seeing is the energy and frequency at that specific point and no where else. Put your probe on the other side of the coil and see for yourself. Or include several taps in the coil and put the scope on those points (only use the probe without the ground)) and you will see how the energy decreases as you get further into the coil. So in your mind you have to think that there is a gradual change in the initial impulse. This is very common unless you are working at much higher frequencies in which case most all components will show the frequency.
More to come.
