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

[amigo]

Hi Marco,

That's pretty interesting about backlight inverters in laptops, I'll look some up if I can find cheap.

Something else came to mind, I am not sure if you have seen that video with Eric Dollard called Transverse and Longitudinal Electric Waves?
To make the story short, in it Eric says that using the analog networks they have devised (basically combinations of chokes and capacitors) they were able to achieve high voltages and behaviour similar to Tesla coil's but without the big coils and spark gaps. They have used a generic signal generator passed through an audio amplifier to boos the signal up into those analog networks.

Do you have any knowledge of that, how it would be done in our present times (using more available solid state components)?

Thanks.

Hi,

Here is my latest circuit design, revision no 07.
Combining with Time Energy Pump (i hope it's right or relevant). Honoured Jean Louis Naudin
3rd coil  act as feedback coil too.

Wow, and now i got more longest than before. Battery drain very slowly. Only 0.003 Volt every 30 minutes !!!

Anyone could help me to see on oscilloscope at point transistor collector lead.

My friend will arrive at my place on 8th April 2008, I hope he will tell me what i should do.

Hi zon,

What frequency is your toroid rated for because there are many different kinds and they are colour coded for specific frequency ranges/responses?

Thanks.

@amigo

I don't know the frequency , I've got.
My target as my friend's concept between 30 Khz to 350 Khz
I wound 1200 mm coil on that toroid size.

@zon,

I've tried your modification and my result is the same/similar to my earlier circuit (groundloop design).

2N2222A transistor, 60~65mA drainage. I somehow cannot get the circuit to >30mA like others do. The funny thing is that the drainage is the same with 1,2,3,4,5,6,7,8 and 9 LEDs. Still at 65mA. In fact, the current drops slight from 1 to 2 LEDs.

Strange.

Now voltage dropped to V556 and current at 20mA. Removed all and leave only 1 LED. It is still bright.
