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

[gyulasun]

Hi Zon,

Ok on the schematics correction,  now the neon bulbs' connections make more sense for me, although I am still puzzled by the role of the third bulb in parallel with the LED:  usually a white LED has a 3.1-3.2V forward voltage drop and a neon bulb usually is a totally open circuit at such low voltages...  so what is its role?

Re on your earlier news:  Good news.
My friend want to share what reference he use for build T02.
Look at http://magnetism.fateback.com/Sweet.htm
I found that similiar coil setup (not exactly the same).

I ask if there is any further news on the T02 transformer?  Unfortunately I am puzzled by the reference link theory you gave the link.  Do you understand it?

Thanks, Gyula

@gyula

I haven't continue T02 transformer because it's not my design
Here is some clue (last answer), he never told me , why it's works.. he just built and go.

Hi ZOn,

Thanks for the drawing, seems interesting and mysterious...

Have you managed to measure your LED current already?  Sorry I forgot to mention to switch the battery out before disconneting the LED for current measuring, otherwise voltage goes up high DC on the cap...

By the way, do you keep on operating your latest circuit for 3 weeks now and battery voltage more or less stays around 1.2..V ?

Thanks,  Gyula

Hi all
Mi circuit, zon revision 16:





The wire diameter is not accurate. The magnets (in a pic) are of an old hard disk. I ignore the distribution of the poles, i think left-right, not up-down

Observations:
BC549b drain 25.4 mA
MPS2222A drain 40.7 mA
2N2222A drain 61.8 mA

BC549b:
across Led: 2.9 V
2 Leds drain 25.8 mA

I don't observe effect with magnets, different sizes of magnets, battery drop slowly. But with strong magnet (see pic 3) if magnet touch wire the led not lights. I have used a (hitech ) cardboard separator.

Time   Battery V.
00:00  1.325
00:12  1.324
05:00  1.208
17:00  0.883

Hi Hhx,

many thanks for the replication trial.

Well, as long as we don?t know the exact effect behind the circuit from user zon
and his friend, it is very difficult to get the same effect with different parts...

@zon,

what are your 2 hexagonal  magnets made of ?
Are these ferrite magnets ?
Where did you get them from ?

also what is the cut off text of your last circuit diagram at the top ?

Can you scale this circuit up,
so that it constantly light up 10 to 20  LEDs brightly from maybe 3 or 4 batteries
without dropping the voltage ?

If you can scale this circuit up into the 1 Watts range, that would be really great !
Many thanks.

Regardsm, Stefan.
