@br549,

very nice stuff. I also believe weight and length ratios are very important, and try to incorporate them in my builds/replications. The two allegedly succesful Don Smith replicators stoker_x1 and Ming Cao said primary(s) should be 1/4 the weight OR 4 times the weight of the secondary(s). Nick Gianopolus from PJK book, who claims to have build OU device with 2 Tesla coils, says the same...

totally IMHO: I think 1:1 ratios work too, but maybe with worse efficiency.

kind regards

In most cases, the scope probe references (ground clips, BNC shields) are connected together at the chassis of the scope and also are connected back through the line cord to the housewiring "ground" wire, which may or may not be at the same potential as your true Earth ground shown in the schematic. This is also usually true for the Function Generator "black" or shield output lead. If you turn off the equipment and use your DMM in the "continuity check" or low Ohm resistance range you can check this ground continuity to see if it is true for your test equipment. My old Interstate F43 has a "chassis isolation" switch and fully isolated BNC connectors so its output can be completely disconnected from the chassis line cord ground, but most more modern FGs apparently don't have this feature. And of course as soon I connect even the isolated F43 to another instrument with a BNC patch cable, like a scope or frequency counter that is chassis-grounded, this isolation is lost. My Link DSO (computer parallel port based) has both probe shields/references connected together at the chassis, and also to the parallel port "hood" and thus to the computer's chassis ground,  but uses a 2-wire "wall wart" power supply so is isolated from the line wiring Earth ground, at least. Both my analog scopes have all probe references connected together at the chassis and also back through the 3-wire line cords to the house wiring Earth ground. It's easy to create unintentional ground loops if I'm not careful to connect all grounds/references to the same physical point in the circuit under test.

It would be interesting to know if your FG and scope probe references are 1) connected together at the scope chassis, and 2) connected to the line cord ground wire. Could you do a continuity test for us?  You may have actually connected your FG "black" output lead and the scope probe references to the circuit's Earth ground point after all, through the groundloop from the instrument chassis grounds and power supply cords.

I had though about a ground loop between the signal generator and the scope a while back , so I  plugged the signal generator into my 12VDC to 120VAC inverter and got  the same results. I thought I may have miss read the results the first time so I just tried it again, (same results?). I also tried to plug my scope into an inverter, but the scope has a real hard time locking onto anything. Not a true sign wave. (Freaks out the scope).

Been working through some basic coil experiments and found this one interesting, so I thought I would share it and would
encourage any positive feedback and comments. Along with the current circuit is a little video explaining my measuring
process and results.
Have a Great Day

Hi br549. Your measurements are not correct. You must take phase difference between current and voltage
waveforms into account, (you can't do that with the way you connected your probes), and you can't rely on the
RMS readings of your scope, as they are typically not very accurate unless all the waveforms are sinusoidal
and very symmetrical about the 0 line, and not distorted waveforms in any way. You will have distorted waveforms
on the LEDs for example. There are other factors here that can affect measurements as well.

Hey Jeg.
Happy New Year to everyone as well....
All the best...

From other Planet:
I tried different gauges of wire (same Length, 42") on the secondary, and it does seem to make a big difference. I'm not going to bore you with all the different sizes that I tried, but the present size and weight worked the best. I did not try multipals of L1s weight (like 1/4 or *4) but I think I will do that next. I'm not sure if I am on the right thread for this kind of experments, If not do you know a more appropriate one.
As always Have a great day

Thanks for the drawing FOP! It is really interesting how this diode arrangement works. I always thought that Carlos had purposely mistaken on here. Is there any case for you to have the same effect even if you disconnect the lower diode from your circuit?

br549, well done with your results. Take in account Tinsel's and Void's suggestions and try again. I think that you are almost there..! This primary and secondary weight analogy looks like very important.. Thanks for mentioning it!

Hi Forest! Those days i was looking at your last years posts and i see that you have a consistence at your suggestions and propositions. You mention some very interesting facts which i have cross checked in Tesla's interview, like the importance of low ohmic resistance in tank circuits combined with hi inductance coils. You also mention that there is a specific ratio between those two characteristics for making an oscillator to ring almost for ever. I wonder if you found out a ratio threshold or something that worths to be tested..
