Selfcharging cap circuit from Larskro fake or real ?

So, that motor is from one of these?

Yes it looks pretty like that, except the threaded end is on the outside for the ebay offer and Larskro shows such head with the thread obviously inside because of the thicker collar ending where he helds it.  https://www.youtube.com/watch?v=jmG-MaijNv0

But this mechanical fixing difference cannot matter for the built-in generator, so it is very likely that the same type of generator is embedded in the ebay offer.

Here's another type of mini generator. This thing/torch has button cells in it which get recharged, I thought that odd. But even if the switch is off the LED's light up when pumping the mechanism to spin the magnet. One pump and the magnet spins quite a while. I guess it depends on how charged the batteries are.

Anyway the coil can be changed fairly easy on this thing I think. This one has a disconnected LED wire so I thought I would show it here while I had it apart.

I'm not sure but I think that the thing probably never actually sees AC from the motor coils, except in the sense of the inductive ringing. I think it's operating as a quasi-synchronous pulse motor. So the coil is pulsed once, briefly, during one half of the rotation and coasts the rest of the time. There will be some generator effect during the coasting probably but I can't quite wrap my head around it without actually having a working apparatus in front of me.

I tried another micro relay, had it all wired in, only to discover that it, too, has a diode across the coil. So I'm going to have to build my own little motor I guess. And dig up a plain reed switch from somewhere. Although I have been playing around with a Hall effect sensor; maybe I can get that to substitute for a reed switch.

Okay, thanks.

Using a Hall effect sensor sounds a good idea, its open collector output itself might be able to survive the peak voltages.
I will ponder on a kind of controlled rectifier too.

Hi Farmhand,

PRobably the generator you show is able to work as motor when you give pulsed DC or normal AC to its 'output' coils?
I mean there seems to be no brushes and Larskro's generator also seems brushless so this is why I ponder,  chances are the type you show can work also as a motor.
