Single AA battery to light WHITE LED for long-long time

[Feynman]

Here is me replication of amigo's circuit.   We will fix this soon! 


C'mon... light, little one!!!




And here is my replication of groundloop's circuit




I will post scope traces as soon as I can locate an ample supply of beer.  Since it's after midnight, this might require a trip to local bar.    
EDIT:  I just found some Guinness.   

For the spark gap , I am trying to reach a contact at a university lab which has microscope. Suffice to say we can thank JetBlue and the generous budget of Duke University.

As promised, here are those scope traces from groundloops circuit, which is pictured above.




Circuit frequency is approx. 20khz.  And now for the energy measurements... which were surprising...

Battery Voltage:


Drain at LED (milliamps):


I didn't believe this number so I checked the analog meter


Well the gear says it's official.  We are using about half a volt and under half a milliamp and we are lighting a blue LED.  Kinda cool  huh

Did anybody yettry toimplement a sparkgap from dissimular
metals like copper and graphite into this circuit to
have a real recharging effect of the battery ?
At these low voltages you have to use probably mikrometer distances.
Or use a higher turn additional winding where you have High Voltage from the transformer
and feed these sparking pulses back to the battery.

It will be then based on the Newman effect and is a direct conversion of graphite ( carbon)
into electricity.

Ich denke, dass niemand die Funkenl?cke noch gemacht hat. Ich werde versuchen, Ein in den n?chsten wenigen Wochen zu machen. Ich denke, dass wir die Entfernung kalkuliert haben, muss 4/1000 cm sein. Nachdem ich Zugriff auf ein Universit?tlabor ich erhalte, werde dies versuchen.

Vielen Dank f?r Ihre Ideen. 

PS Warum verschiedene Metalle f?r die Funkenl?cke?

I think that no one yet made the spark gap.  I will try to make one in the next few weeks.  I think that we calculated the distance must be 4/1000 cm.  After I receive access to a university laboratory I will try this.

Thank you very much for your ideas. 

PS Why different metals for the spark gap?

Marco,

In the second photo, the motors appear to be wired in such a way that the HV actually passes through them, with opposite wires connected to the case of the motor and the other ones leading away. Is that correct?

You also say to magnetize the needle, do you mean the rotor shaft?

Thanks.

Hi Amigo

The mechanical spark gap as shown with the DC motors is not for use in a HV setup.
They can be used in HV setup but then you need to spin them with a battery or something externally.
The motors are wired in series and though their cases in such a manner that when the rotors touch each other, the motors start to spin.
By magnetizing the tips that are touching each other you can keep it running fine but you can also mount the motors with tape or whatever.

You can raise the voltage by using more numbers of turns and redirecting collapse via diodes.
This way you can easy put in like 9Volt and get 200Volt Out as a spike.
