Hi guys! This tread is a place to share my experience with the POC. It will be as simple as I am. So do not ask for measurement, it all about the phenoment. Hope you will appreciate and participate! π

Here are one of my first experiences with the POC.
Hey Wistiti,
Excellent thread!
My first Experience with POC was experiments prior to Jul 18, 2011, published in this video:
These experiments included observing the necessity for Current Flow:
Floyd Sweet making the same observation:
If the voltmeter draws no current, there can be no electromagnetic force on the free electrons of the wire. Therefore, the E.M.F along the path of the metal conductors including the moving conductor is zero.
Its worth noting, the Positive Energy passage talks about Clockwise and Counter Clockwise E.M.F's. Directly after this passage, Floyd Sweet talks about: INDUCED MOTIONAL FIELD - NEGATIVE ENERGY, unfortunately there is not much useful information in there.
Any and all Insulated Copper Conductors when carrying a Current have an associated Magnetic Field. Voltage can be present with NO Current! Current is a function of the Load and the Source.
Chris
Completely agree Chris!!! And I will add when using DC for the source, the current from the output POC must be extracted to buck the primary DC source... Like I do is this video. (Sorry for my English) π

Wistiti, one of my favorite videos of yours!
I started with a few small, for most perhaps insignificant, effects. Just a few coils, having a bit of insight, looking for something. Knowing in my heart that there was something to find there. Took me some years to make real progress, much confusion and mistakes along the way.
You my friend are a natural! Also, your English is perfectly understandable!

Hi wistiti
Very interesting this video. I take note of it.
You know in this forum we learn things that move us forward. Thanks for sharing.
Jagau
Yes my freind!
And this is (openly sharing) what we move us forward! Thanks to Chris to bring it back to us!!!
Now it's up to us (as a team) to improve it!

Hi guys! Just let you know I have passed the last day's playing with POC.
I build a toroid transformer (really long to wind on a toroid...π) on a plastic ring (so air core) . The effect is there but way less than when using a magnetic core. The couplings seem not optimal... I will continue my experiment with magnetic core. π
That toroid looks awesome. If you have only been playing with it a day then its too soon to give up IMO, but you need a signal generator to get the most out of it. PM me if you want to sell it.
Thank you Zanzal ! I have not yet give up on it. It took me so much time to wind it I will keep it for further test. π I don't have a signal generator. But agree, it might have a sweet frequency spot. Have you a good one not to expensive to suggest?
Yes, I don't blame you, it is a work of art, personally I'd mount it on my wall before I sold it had I built something so nice.
Regarding function generators your best pick for a starter is the JDS6600 15Mhz for $65. For a more complete answer I posted more options in the Function Generators thread.
Nice coil Wistiti! Agreed that a function generator will be useful, resuming the latest information we have to look for magnetic resonance, and the frequency depending on the corematerial, so we can assume that for an aircore much higher frequencies will be required, like in the aircore devices from Don Smith. Also a disruptive discharge on the primary could likely set up a resonance. Wish you success , Vidura.
Thank you Vidura . Disruptive discharge is the way I explore now to improve the effect.
It seem to be a must... I'm looking for a way to do it at low voltage. I try with a reed switch at the base of a transistor and have interesting results but I'm wondering what are the other ways I can make this kind of abrupt discharge without hv and spark gap...??π€
Any idea are welcome!
As a suggestion i had good results with a mosfet and capacitor array, one device you can see in many of my vΓdeos, it has five mosfets in parallel and a capacitor bank on the supply rail and with very short dutycycle it give good pulses for striking the resonance. Also a SCR with a neon as trigger works very well at a little higher voltages. Sorry that I cant load up image's until fixing the internet installations, my phone dont have enough memory to do it. In a few days it should be up again ,then I can share some circuits I have used.
Any idea are welcome!
You could try using an avalanche pulse generator. Basically you need a HV source, through a resistor you charge a HV low pf capacitor, the capacitor gets discharged when it reaches the avalanche voltage of the transistor. You can adjust the frequency of the pulses by changing the resistance, but you want to keep enough resistance so that the capacitor cannot recharge too quickly after discharging.
You set the voltage by using a number of cheap transistors with a known avalanche voltage in series. So if you use an npn with an avalanche voltage of 200V and you want 600V pulses you just use 3 of them in series. Keep the capacitance low to avoid damaging them. So at 100pF it might be ok, but 600V at 100nF you might have dead transistors.. Or that's how I understand it anyway (never built one myself).
You can see an example of the most basic one like I described here: Avalanche Pulse Generator Circuit
Thank you guys for the info! Vidura I will wait to see your picture. Have a good day!
Hi freinds!
I have a spare time to experiment and i want to share my findings with you.
I have rebuild the Skywatcher bucking coil inverter and have good results.
Since now, im charging my 3rd 12v 7,2ah battery with a 5v 5.3ah usb power bank.
The usb power bank have drop of 0.03v and im toped 3 12v 7,2ah batt to 15v!!
The new thing i have done is give a space between the POC on my ferite rod. The primary is still a joule thief. The output diode have to be oriented the good way to assist the primary.
My little bit to share.
Keep on experimenting!!!!
Hey my friend,
Very nice! Excellent work! Power coming out at both ends!
Chris
Thank you for your report of the interessting results.
Do you have a schematic of the skywatcher poc circuit / coil windings?
Regards Roland

Sure! Here it is. Make sure to have a space between the POC. Reverse the diode to have the best output snd see a reduced consumption of the primary's when the secondary is loaded.
No one online at the moment

Ere many generations pass, our machinery will be driven by a power obtainable at any point of the universe. This idea is not novel. Men have been led to it long ago go by instinct or reason. It has been expressed in many ways, and in many places, in the history of old and new. We find it in the delightful myth of Antheus, who drives power from the earth; we find it among the subtle speculations of one of your splendid mathematicians, and in many hints and statements of thinkers of the present time. Throughout space there is energy. Is this energy static or kinetic? If static, our hopes are in vain; if kinetic - and this we know it is for certain - then it is a mere question of time when men will succeed in attaching their machinery to the very wheelwork of nature.
