No so fast, please. The LED is on the INPUT side of the DC2DC converter, as Nali2001 was so kind to show us all. Thanks again Nali2001! Therefore, the LED can not be powered by the driving circuit (Yes, I was aware of the protection diode; I’ve pretty much did my homeworks, have entirely read all thread and carefully followed it in real time but until now I was simply silent, except for the older post you found where I could not be clear enough due to time constraints and language barrier.)

To save everyone’s time, I’ll use this post to clear another other issue too:
The motor consumes  about 1A at 12V and full speed; Stefan pointed out that input current is maybe decaying exponentially. I’m not certain it decays at all because the start-up current is around 2.2A so maybe it does the opposite, increasing at low RPM. However, even if current decreases, the exponential is in respect with actual RPM alone (and nothing else, for the given setup, but RPM) and because in about 3s (time the capacitor discharge time on 10ohm load, which is in good fit with my initial estimate of 1-2s that I derived from the RC time constant,) the rotor does not slow down considerable, the exponential decay of current would be very slow (almost negligible). In short, a gap of more than30-35s remains unexplained and unexplainable imho.

I’m glad Romero is back. Maybe he can enlighten us but so far please don’t accuse me because I was right so far.

Best regards,
Tinu


PS I apologize for the members who could not follow; please see the last post of redrichie, namely the following quote: “My laptop power supply has a led indicator light.  sometimes it stays on for up to a minute after I unplug it.  My laptop must be a fake.”
For how long stays the same led on if you turn on your laptop, with your power supply unplugged?!
Same issue here. I wasn’t talking about 47mF/15V cap discharge on a LED and 1K resistor; that’s indeed tenths of minutes, maybe hours…

@RomeroUk,
I think many understand your situation, however many people are attempting to replicate your device including others who do not post here but observe. There seems to be a lot of confusion and debate about how many of the components are wired. I know you have indicated (and I am sure everyone understands why) you do not wish to further contribute, but perhaps you may be kind enough to do a simple hand drawn wiring diagram with all the components (like the feedback diode). This may assist many from blindly feeling in the dark and through application gain some of the understanding you have that will not be restrained by normal physics. This is a real paradigm shift for many.

PS Chris C..can you email me..I am in the USA next week.

hi Romero

happy that you are well

OK for me the work goes on

And having wounded a second coil with exact same quality as the first one, i can situate the voltage at about 24 volts for a binome coil under no load at 1280 RPM

And also confirm that this binome of coil can produce about 2 Watts , so 7 time 2 watts could be a 14 watt. I hope the litze will bring more, but waiting for my delivery.

Something to further check is that , under load, the voltage comes very fast up to arround 1200 rpm and than very slowly . I pushed up to 1600 rpm without a lot of gain.  ?? Seems to be a threshold at some point depending of each config.!!

OK good luck and fun to experimenting at all

Tinu,
What is it you just don't get!
Once the power to the coil drivers are switched off, the output of the DC/DC converter goes to 12v or higher because of the recovery diode.
With no load on the DC/DC converter but with 12v still provided from the large 47,000uf capacitor the only draw is the LED.
How long could a 47,000uf capacitor keep an LED lit?
D.A just give it up!

@tinu, maybe you miss 50% point of this thread and romerouk point (not talking about the LED ).
1) we are searching for an undocumented effect, so there might be no logic about it, just a simple observation result
2) people here like to build and analize things
3) romero asked the guys who know what they are doing to ivestigate this interesting setup and share their conclusion

So, sit back and enjoy the ride ? Even if this proves to be "fake", i think there are interesting parts of this circuit that are worth at least investigating by most of us. If i could afford the time i would not care 1% if this is fake or not, would build it myself just for fun.
