With all of this quiet I'm wondering if anyone figured out why one of the hall-effects is not facing a magnet.
Instead, it faces the side of a coil.

Please elaborate.

This is not related to your question. I think I realize something about this device that did not dawn on me earlier but I think it is a very important aspect that has been overlooked.
I do most all of my own experiments with coils and my two pulse generators. My baseline is simple. I always use the same output retrieval via a diode to one of my many capacitors. On the cap I will put an LED bank that starts lighting up at 5vdc, plus I will have a volt meter reading the cap. If something happens out of the ordinary, I will see it right away. At 3vdc I will only see it on the meter. At 8vdc on my meter, my LED will be blinding. This is not peak to peak but more an RMS voltage since it is the voltage with my cap loaded. I am not really concerned about precise , measurements because I can still see the gain or loss happening in real time and know from experience what is going on when I make slight changes to the device under test.
But what I have most is that the diode on my capacitor is not one diode, but a terminal holding 6-7 different diodes pointing in parallel to the cap with other ends open. When I pulse a newly built coil or device, one output is on the cap and the other in my hand and I will try each diode and read the output and look at my led bank. Some diodes will give nothing on this new coil but other diodes do give and one of them will give the most. That is the one I will use for this new coil.
So for me, I would say there is something wrong with guys building an elaborate wheel, to then use a standard off the shelf fwbr. Something very wrong indeed. For me, on my own bench work the output diode is the most important and first component and should be chosen with lots of care since all future tests will be dependent on that diode working in the range I am working around to pass and hold my output.
Standard fwbrs are usually used on the secondary of clean AC 60hz driven transformer coils. They may not have the right specs or attributes for the outputs you guys are working with but I could be wrong, but I don't think I am wrong. In any event, you can test your own diodes with your wheel to see if you can find better diodes to make your own fwbrs. Seems to me the standard off the shelf type may be working against your outputs and guys may have to do what I would call "output diode hunting".
What I would do is this granted it is much more trickier to do with a wheel then a set of coils.
Set up your output capacitor. I would say any non-polarized cap with 100uf or more should do. Find all the diodes you can get and make yourself a diode bank as shown below. Put an LED Bank or small bulb on the cap along with your volt meter and even your scope.
1) Run the wheel with only one gen coil, not a pair.
2) Connect one end of the coil to the open terminal and by hand use the other coil end and try each diode one by one checking the output reading on the meter and/or the bulb brightness.
Yes I know with AC it is more confusing but that is not important. With one diode you should be able to pass half the cycle and see how the diode let's the energy pass at your nominal rotor rpm.
3) Once you have found the diode producing the highest or strongest output, use that model to make an fwbr.
4) Try the fwbr on the coil and put the dc output on the cap again via the diode bank to find the best output diode.
Don't take for granted your EE skills in this regard because there are no calculations to predefine what you are looking for. Well for me anyway. I am more hands on. My opinion, the only real component that has been overlooked by all builders is the fwbr and it just so happens that it is the most important component of the lot.
If you change major working parameters or output coil connections, like from parallel to series or to cascading, you then run the device again that way and hunt for the best diode once again. It may be the same you had, but don't take a chance because your next umteen tests will depend on it. Once you have it, keep going.
I guess what I am trying to say is if the wheel is not an ordinary output method then why would you suppose a standard fwbr is all you need to make it work? Whatever method you can elaborate yourself to find the best diodes, since some may elect to make two diode banks each pointing in opposite directions to quickly test both sides of the AC coil at the same time, it is just more fun.

PS1: Find your own diodes for your own device. Even if someone tells you to use this one or that one, get as many types as you can on a terminal and test it anyways. Be sure for yourself. Each device will have its own.
PS2: Found this ready made coil. Looks very interesting. What do you think for a small test wheel?
