New videos found on youtube, tiny generator with 2 coils

[Poit]

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...

Exactly... Leds can be very deceptive with their input current. This forum knows all to well that Leds can run as low as Microamps.... so for this guy to ASSUME that ALL 75 Leds are running at 25miliamps is stupid! especially since he doesnt messure it. This fella knows his way around a multi meter... he shows the voltage .. can do ohms law etc... so why oh why did he not do a current check on the leds?!!! all he had to is hook the multimetre up in series with it!!! NOT BLOODY HARD!

I know why he didn't... because it wouldn't be impressive any more... think about it... he tells you EVERYTHING.. even the damn hertz the thing runs at... EXCEPT for the current and voltage draw on the leds (the 60 volts he shows you is UNLOADED, means nothing)....

his maths =

"75 leds = 1 led = 25maX75 =1.85Amp"

sure.. thats about correct.... but he fails to mention is that his leds are running below 2.5miliamps per led.. giving a total of 190miliamp draw..... hmmm.... 200miliamp going in.. 190miliamp going out....thats a net loss of 10miliamps.. AND thats being extremely generous... its  most likely going to be a 20 - 40 miliamps loss..

He would be better off connecting the super cap / lithium battery (depending on which video you watched) to a joule thief and then running the 75 Leds... would run for longer than his contraption.

Can anyone speculate what is  this component(s) held by the left hand?

Interesting videos

Hi Mike,

I think he has two button cell batteries in series in the lower part of that component (this may explain the 2.4V) and there is a Neo cylinder magnet attached to the top part of the 2.4V battery pack.
(here is such a battery pack, searched at random by google, he probably removed the solder tabs from the outsides of the batteries:

Regarding the creation of the 63V or so DC voltage in the capacitor I think he uses a reed switch hidden inside one of the coils and this reed switch probably is in series with the coil to interrupt the 2.4V battery current and the spike from the collapsing field is also rectified by the diode bridge.
The type of the capacitor cannot be a supercap because in that small mechanical size supercaps normally have 2.4 or 5V DC ratings.

There is another possibility: the reed switch is not in series with the coils but in parallel and performs as short-circuiting the coils at the the induced sine wave peaks. See coil shorting technics elsewhere in this or at other forums.

Hi Gyula
Yes, it doesn’t look like neo mag(s) or capacitor(s). As you commented it looks like a battery.
A small alkaline 23AE comes to mind too, outputs 12V or button cells.
So there may be a battery power source there in the system.
