Two things:
The ring configuration is in the vein of the ECD and the scope shot shows major promise. The ringing shows up symmetrically in the
on time. But the
off time has a higher peak to peak and faster oscillations. This is most important! The self oscillation start is in the
off time. His scope shots show the same pattern I started with. The next test is to
reduce the on time or change the
on time to 25%. His signals are 75%/25%. You want the
off time oscillations to overlap the back end of the
on time ringing. In other words
'The two sets of waves will overlap'.

Then you see the consecutive spikes building. We push the swing at the correct time...
The constant DC at the back end of the
on time stabilizes the polarity of the electron torque. All is quiet. This stops the oscillatory function. Then the
off transistion has to start up again only to loose any reverberation that might happen. The reverb or echo is necessary to start an acoustic or wave tidal imposition. This whole process uses the established wave content or standing wave as a bias or stored energy. That is the constant resource that resonance supplies.
Here is what I have seen: The coil produces intense noise in the
off time. If the duty cycle is lowered the next check is to see where the
off time oscillatory function stops along the
off time window. If it stops short of the impending
on time occurance then 2 things have to occur. Change the input frequency or the coil winding/configuration. Sm stated he 'snipped wires'. This can happen in alot of ways and do alot of things.
Now the unfortunate news:
This is the feedback process that is like a teseract in a house of mirrors. You change one parameter then go to another part of the configuration and adjust something else. It could be electrical or mechanical. That is the nature of the beast. I got to this point and the next step is to work the power output stage. In other words:
Once you have established the echo you then need a target. Whoa!
Previous efforts have attempted to drive a coil to get power. This is basic transformer action and will not work. Doesn't matter if you use square, sine, or spark gaps. Just because you step on the gas doesn't mean you'll make it around the corner faster.
