New videos found on youtube, tiny generator with 2 coils

@Low-Q

What you say makes sense, especially when you consider the software running on the laptop is for RC aeroplanes !

I think these are just 2 coils between a magnet rotor.

The basic circuit is this as the attached circuit.

Sorry for the bad resolution, it was just done via my crappy phone camera.

Maybe he just uses the bifilar windings in each coil just in parallel to get
more capacitance inside the coils.
Or are there really more than 2 connections on each coil ?
In the first movie he uses a 2.4 Volts battery to run it which consumes
100 MilliAmps, so he is using about 240 MilliWatts of input power.

In the second video he is charging up a big cap, probably a supercap
from 2 batteries at the beginning of the video and uses it to run the circuit.

The question really is, if the rectified 60 Volts DC output has more
power than the 240 MilliWatts of input power ?
The LEDs are not very bright ...Hmmm...

My Spanish isn't very good, but this is how I read the description on Youtube:

“This motor operates on the basis of an electromagnetic field which is self-induced by coils that repel a rotor which consists of a magnet that has a flywheel with two weights below it to create inertia. A battery is connected as the initial source of power, supplying 2.4 volts which turns the coils into electromagnets. The effect of rotation on the coils is to produce in its turn an alternating current in the secondary winding of each coil. This alternating current is taken and rectified by diodes as pulsed direct current. A capacitor is used to smooth the current, yielding 60 volts as a result.  The coils work as inductors and as transformers in turn. Each coil consists of two windings of wire. The motor consumes 100mA, and the rotor turns at about 7000 rpm.”

On this basis Stefan's circuit diagram is an over-simplification, as it omits the fact that the the diode bridge takes its input from secondary windings.

This device looks a bit like a cross between the Turtur device (modified so that the magnet rotates in a magnetic field produced by primary coils that are connected to a battery), and Muller/Adams/Romeruk devices which rely on the interactions between coils, rotor magnets and stator magnets.

It's worth emphasizing that this device, like the Turtur device, does not seem to have anything that you can describe as a driver coil, and has to brought to its operating speed by an external starter (in this case, the Dremel).

You could look at this as a variant of the Turtur device in which the resonator is provided by the primary circuit so that an alternating current is produced in the secondary windings.

Edit:
@allama: yes, you are absolutely right,

sorry on misleading you guys in wrong direction, I remember similar device from 2005 or so that had 4 magnets and used one as energy source

Hello. I´m spanish and i think that the schema could be this one, with only one magnet (youtube video description says that the others are only weights)
