I saw your last two vids. Great move and love them crickets in the background. Very soothing. Very zen.
So to simplify this discussion let's just call the iron wire the primary or pri. The secondaries as sec, secs (not sex) or sec1, sec2, sec3 where sec1 is the secondary closest to the make break side of the primary.
I know you are presently into pulsing both the primary and secondary and i will weigh tin on that on another post later but I think without changing the build there are some preliminaries needed. @szaxx I am also following your foray and wish you the best. My lack of comments is to not mix up things more then they should be.
OK, where to start? Your pri is now x length with 10 x 4t secs spread evenly on all the length and not just the first half, so just leave it like that so we can all learn a few things as it is.
By the end of these trials it should give you a better idea on what is going on and what resonance is in a wire. This may be somewhat tedious but in such conditions one has to take this methodically and you will quickly understand why.
You will need some paper to take down some values as you go along. You'll need a fast diode like the 1N5817 or 1N5819 going to a capacitor. I use a 10uf 370 volt, but whatever you have around should do as long as it is not too high in uf. The tank will act like an rms agent so readings will be steady. Depending on the pulse strength, you may elect or not to put on a few leds as a load as long as they are used throughout the test to produce that same data. A volt meter across the capacitor would be a good idea or you can use your scope since it does give out the voltage readings but if voltage gets too high please be careful with the scope.
There are two ways to use the pri. Either it is pulsed to the sec resonance or pulsed to its own resonance. We'll start with the former.
So you pulse the pri to the sec1 resonance, write down the pulse frequency, width and amplitude and the voltage reading or grab the scope screen. Repeat for Sec2 and so on. Resonance point will be the point of highest voltage output. As you approach Sec10 if the voltage readings are too low just try to find any peak possible in the same range. So you will have 10 data point lines. What we want to see is if the resonance frequency for the secs are in the same range as we go from sec1 to sec10 and what are their output levels. We also want to confirm the sec polarities at resonance.
OK, next. This time you scope the pri and pulse it to its own highest resonance point and keep it there so it does not change. Then tank and read sec1, then sec2 and so on and write their voltage outputs or scope grabs. Here as well we want to see how a pri at resonance will be conveyed to the secs as you get further from the make break point.
Hopefully with the above small tests these will open up new avenues for you and others to see and anticipate effects and figure out news ways to do small tests that tell you more then most big checkmate builds.
OK, another point. When you have 10 secs that are in parallel on one pri, if one of the secs does not output its fair share of the total output, what does that sec become? Right, it becomes a load like a heat source. If one of the secs polarity is not in sync with the others what does it become? Right, it becomes a cancellation source. These all have to be checked one by one to then confirm all 10 secs are confirmed for polarity before going to parallel.
After these small tests we can have a good discussion on what was learned and then we can explore ways to then integrate SMs discussion about the canon to cannon effect with this same build.
Hope I am not overburdening you or others who may think this is all useless.
Keep up the good work and most important don't lose the passion.
