Self resonance circuit

Hi justawatt,


Please reduce the size of the image in your second post so it fits the format of the thread.


Why are you calling the circuit in your first post a self-runner?  As soon as you disconnect the 9 volt source the circuit will stop.

Ruslan has said in the past that Akula was very tricky and that this circuit is basically
some sort of trick. Ruslan said the circuit self runs, but that the ferrite core gets destroyed
(crumbles away) after running for a while. Ruslan didn't elaborate on why the ferrite core
gets destroyed like that after running for some time. Sounds like possibly some sort of galvanic
battery effect might be at play if the ferrite core breaks down and crumbles after running for a while,
if Ruslan was telling the truth.

Akula did wrap a strip of copper foil around the ferrite core from what I recall. I think iron has a
galvanic voltage around -0.65V and copper has a galvanic voltage around -0.35V, so that is only a
voltage difference of about 0.3V, but if that generated galvanic current was pulsed though a coil it might
be enough to power a low power switching circuit for quite some time. If you have a galvanic battery with
iron being more negative than copper, which metal electrode will get eaten, the iron or the copper electrode?
If it is the more negative electrode that gets eaten, then that might be an explanation of why the ferrite
core disintegrated (assuming Ruslan was telling the truth about the ferrite core disintegrating is his replication test). 

Edit: I just looked it up, and it is apparently the least noble metal electrode that deteriorates in a galvanic reaction
between two electrodes. That means it would be the iron that would deteriorate in a iron-copper galvanic reaction.
So that may possibly explain why the iron or ferrite core eventually disintegrated in Ruslan's replication test, and why the circuit
was able to self run for some time.
