The bifilar pancake coil at its resonant frequency

[Grumage]

Thanks for posting that clear schematic.

ETA: When you disconnected your power supply in that video there was quite a nice spark there. What do you think caused that spark?

Dear Mr. Koala.

You're welcome.

That PSU has literally been " to Hell and back " used in many environments, mainly damp ones, the Crock clips are rather rusty IMO it was just some Iron oxide burning off.

Cheers Graham.

I think, Nelson Rocha's circuit would deserve it's own thread - if anything else than because it doesn't contain pancake coil (according to its diagram this coil even isn't bifilar) and it's the only selfrunner in the wild and also author communicating at overunity.com forum in this moment (i.e. of much higher importance than some abstract discussion and frog&mice battles about interpretation of well understood phenomena). For me it looks like Joule Thief circuit with ferroresonance overunity.

when i

Zephir , please don't put words that i did not say . I never say that circuit is a self running . I just say that circuit is interesting, to people that search the OU theme, and could be made easily  because is cheap to be made and could be observed interesting points , and that is one of the circuits that i share in this same forum when i'm working in opensource years ago nothing more .

That is only to show to some that sometimes ask me by my claims and about hi not opensource my work  that in other times if they want validate something they could easily do that, but  years ago .

Hope i being clear about that subject and my position , and i don't need any thread about me or any of my circuit's .
I share in pm even with you , because i don't need to publicity what i do or what i design in this moment , but people are free to try if want .

cheers

OK - if it's not self-running, which this circuit is supposed to be interesting with?

Hi Zephir ,

I already  explain to you in PM what you could observe on that circuit, no is not a self runner , is only one of the circuits , that you could see interesting behaviors, if you don't want replicate them you could see the videos associated to them , Grumage share their own replication , but if you search , you will find other replications by other users even by myself  .
I said that circuit should be used to study some interesting effects .
Like other circuits i made , i use them to study , and of course you or anyone are free to replicate them and see by yourself , and validate them because when i share them was in opensource , and in that way he still remain in same way .
The good new is that you don't need to spend much money to replicate them , but you are free to decide that .

cheers

You simply need to convert to "Joules". The Joule is one "watt second".

yes, the joules are easy to calculate. i guess its all parallel,  so about  10 joules in 3 seconds.

but Im interested in the power that puts the charge in the caps. its not linear,  at first there is a sudden great rise of voltage,  and then when it reaches its maximum voltage,  the voltage rise slows down.
so the current seems large at the start of charging,  when the voltage is still low.

so to say 10 joule in 3 seconds is 3.3 Watts would be wrong.
I wonder what power could be used. if i would put a load on the capacitro,  and the voltage would drop to 12 volts,  howmuch current would it be able to provide.

for me its a though question. also,  because its part of a resonant system, that needs to keep resonating.
if any one could shed a light.

@ Grumage,  tnx for posting that schematic
