3v OU Flashlight

[T-1000]

Hello everyone,

As the topic was brought up after years of silence, I would like to share little secret behind this little device.


The whole circuit is making ferro-resonance which in turn is making strongest magnetostriction possible. Because it is also electrical resonant system it does not take much for this effect to happen and is running close to unity in terms of COP. Just that is not enough for making circuit self-run and the second source of power is needed.


And here is where Piezoelectricity effect utilization comes into action. While having grinded piezoelectric ceramic material film on top of copper foil and having 1 foil inside of coil and 1 foil outside of coil will make good mechanical power conversion into electricity (which would be wasted otherwise). Make it right and it will give decent high voltage power from resulting magnetostriction vibrations. Then feeding that back into circuit makes device run for weeks or months until ferrite core finally breaks into pieces from mechanical damage.


Hopefully that clarify what is happening in those circuits.


Cheers!

High T1000 any chance of a sketch or photo or any other information on this please.

Aliengrey,

LED1 is in wrong direction, because the blue coil of Tr1 gets negativ at the hot end ( while the transistor collector current in the red coil of Tr1 increases) and current is drwan from the positive pole of the battery to this hot end and down to negative pole of battery.

This redrawn scheme also provides data for the number of windings.

Took me 8 hours to read the complete discussion via google-Translator.

Another remark on the winding direction of the three coils on TR1: all coils are wound in one direction.
In the scheme of user GREEN the arc-arrow is wrong ( hot ends are correct )

Hope this helps.

Thanks might have a go at that one there seems to be some stuff that has been thought out and works.

But there is more.
From what I have read the effect is not magnetostriction based but its a prnciple - yet to be veryfied - called "Magnetic Flux Multiplication".
On page 56 user "extreme spin" posted a link to this website here however google-translator does not show the circuit-diagramms
