Ok, i will try to use the BEMF and connect the supercaps...!

Please do not feed BEMF in supercaps.
It will create very tiny holes in the inner structure, making them leak energy. A supercapacitor is NOT able to withstand a higher voltage than rated, even 3 Volts in stead of 2.75 is already shortening the life considerably. A better way to do this is by putting another capacitor which itself is connected with a diode to the supercap (plus to plus with a diode in between from cap to supercap).

A better way to is to transform the BEMF down first, that way you loose less of the possible charge.

Happy experimenting!

Ok, thanks i did the experiment last night but with one of the pancake coils, not with the BEMF, with a rectifier, and i sow that the voltage produced was 6 volts (and with a capacitor 14 volts) and desisted continue the experiment, because i know that i can damage the supercaps...!

I view the problem that you are suggesting as being highly unlikely.  When the BEMF goes into the supercapacitor, the voltage will be very low.  If you start off with the supercapacitor discharged, then the voltage starts at (very close to) zero volts and then slowly climbs as the supercapacitor charges.  If you are careful and monitor the supercapacitor voltage with a mulimeter as you charge it, then you can stop the BEMF charging before the voltage gets too high.

If you are thinking that the BEMF outputs high voltage when it discharges into a discharged capacitor then that is not the case.  The voltage is determined by the slowly increasing capacitor voltage.

The one possible issue is related to how much charging current in amps that the supercapacitor can sustain without damage.  This might be in the datasheet.  My gut feel is telling me that the initial charging current from the BEMF in Skycollecion's setup will not be so high that you have to worry about that.

Yes and no.  How fast the external circuit switches current into the supercapacitor and the inductance of the supercapacitor will determine the peak voltage across it as a result of a switched current such as BEMF.  A little filter placed in front of the supercapacitor will protect it.

Thanks and I stand corrected.  You learn something new every day.

hola Jorge
Un trabajo impecable con los pancakes, felicitaciones.

Creo que el producto mencionado es "dioxido de Titanio, TiO2"
que es supuestamente inocuo para la salud.
el producto recomendado de hecho es una base de maquillaje.

Para info más detallada: http://es.wikipedia.org/wiki/%C3%93xido_de_titanio_%28IV%29

abajo, en referencias, hay un artículo muy interesante (inglés) acerca de su uso
como ánodo (polo negativo) de baterías en una nueva invención:

http://media.ntu.edu.sg/NewsReleases/Pages/newsdetail.aspx?news=809fbb2f-95f0-4995-b5c0-10ae4c50c934

¿ puedes aclararnos para qué uso te lo recomiendan?
gracias
un saludo
Alvaro

Hello Jorge
An impeccable work with the pancake congratulations.

I believe that the mentioned product is titanium dioxide " TiO2 "
which is supposedly harmless for your health. (a face makeup)
see TiO2 in Wikipedia

A very interesting article in the references, about a new invention using it as battery anode

@Skycollection,

Good advice from MarkE:

"A little filter placed in front of the supercapacitor will protect it".

MILEHIGH: Ok, i will discharge the supercaps and i will MAKE THE EXPERIMENT...!


ALVARO: That is that Stefan propose.....: Try to wrap a coil around some Beta Decay mineral and see, if you can exite the radioactive decay with the BackEMF pulses,,,, This way you might get radioactive free beta decay electrons that work like a negative resistance...! [/font][/size]
This is the commentary of Stefan and i don´t know what kind of effect could be the result of using BETA DECAY O DIOXIDO DE TITANIO.[/font][/size]

@Skycollection,

You need to leave enough charge in the capacitors to start the oscillation. Remember, the BEMF recovered is only a fraction of the input, so the capacitor's going to drain and not over charge and explode.

Synchro1: Thanks i know that i need charge in the supercaps to get self oscillation, and if you see my video, in my circuit i have four swiches, one is for the supercpas, one is for the batteries, one is for the BEMF and other is for my saving lamp....!


I can make the experiment with the initial power of the batteries and the supercaps discharged, i have to see what happen with the supercpas with the ammeter...! i think in all posibilities.

Yes and no.  How fast the external circuit switches current into the supercapacitor and the inductance of the supercapacitor will determine the peak voltage across it as a result of a switched current such as BEMF.  A little filter placed in front of the supercapacitor will protect it.

The other usual practice when dealing with capacitors that have high inductance is to shunt them with a high quality film or ceramic capacitor to absorb the spikes. I would also add an excess voltage shedding circuit in the form of a low voltage Zener and auxiliary load so that excess charging can be shed into the load. There are numerous ways to do this in addition to the simple Zener. Series/ parallel strings of LED that begin to light at the appropriate threshold voltage would work if light is the end product needed.

In the case of needing only light output it would be better to eliminate the super capacitor altogether and drive the high current BEMF pulses directly into the LED array.

@Skycollection,

Congratulations! It appears the LEDS just turned on by switch alone, without spinning the rotor magnet to trigger the oscillation. The the new addition of the oscillascope looks very impressive.

Maybe you can start a small factory to begin to manufacture those encased Pancake coils?
