Absolutely no active component. I saw on he winding before covering with tapes.
We don't try it on super capacitor.
He said this FEC , motionless generator ?

Hi Zon,

Thanks,  it is absolutly amazing if there is no active component for changing the flux in the coils or in the ferrit core because the permanent magnets have a static (non changing) magnetic field and something has got to induce AC voltage in the (output) coil for the diodes to rectify...

I have drawn a possible schematics on the FEC circuit from the three pictures as I can see the components connected, see below.  I guess normally the output comes from the 4700uF capacitor but as shown in your photos the output and the battery input is connected together to charge the 1.2V battery, this is why the short wires from the crocodile clips go to the output capacitor.

Now what remains is to find the coils data, the ferrit core material data and probably the poles of the magnets facing the cores/coils...

I like this circuit , I will take a guess and say the magnets have the same poles facing the core (in opposition) but balance this opposition in the core as attraction. Any small imbalance in the core would then produce oscillations which can be maintained with a feedback loop. Tesla once stated a neon bulb is a superconductor when excited having no resistance, but could possibly have external electrostatic effects on the circuit as the wires are very close to the neon's.
Very cool

I agree with what you are saying, yet when looking at the circuit the 100nF is useless, it is in parallel with 4700uF. Any such oscillation would be well below 1Hz, unless the actual feed back circuit is not shown in the diagram??

Yes, I agree with both of you.  However, am I correct to assume that in order for the neon bulb to work as a kind of 'superconductor',  the level of the DC or pulse voltage across it must reach the ON or striking voltage limit of the gas inside the bulb?   which is about 85V for the NE2 bulb type and this is NOT reached because Zon says the neon bulbs remain dark during operation.

Something (either components or wires) is still missing from the schematics but from the three pictures Zon uploaded I cannot make out any better schematics ...  If anybody could improve on the schematics I would welcome him!
Hopefully we can learn some more "secrets"  from this very interesting circuit sooner or later.

Thanks for your comments.

I am constantly "concerned" about the use of DVMs in any of our experiments...Somehow I have a feeling that they are either skewing the measurements or interfering with the measured circuits.
On more than one occasion I have noticed irregular readings, which have mostly happened when the battery power of the DVM was (or nearly) running out. Low battery is not an isolated incident and still I think that even with fresh batteries there could possibly be interference from the DVM to the circuit being tested.

What are your thoughts on the implications of use of analog panel meters as a replacement for DVM in these tests?
