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

[Feynman]

@Groundloop

nicely done!

i can't wait until my toroids get here.

@Feynman,

Why wait? If you can find a non working PC power supply then you have your toroid.
I even found a MPS2222, the two diodes, a capacitor and the resistor in one of my
old (defect) power supply's.

Good idea 

Now I have enough experiments to fill the whole weekend!    All I need now is the favorite local beer.

@All,

I removed the electrolytic capacitor. I found it unnecessary. My 1600mA NiMeh is now almost emty.
I started out with 1,2 Volt (Twelve hours ago) and is now down to 0,585 Volt on the battery.

Now the funny stuff. My ultra bright white LED is still lit. I reckon the light output from the LED is down
to 1/8 of full brightness. The oscillator is still running well. The voltage seems to have leveled out and is
steady on 0,585 Volt. The battery is not being drained anymore?

I will let the circuit run through the night. We will see tomorrow if the battery still holds a charge or not.

@all of u will make replicate

Please keep the ratio of Bedini SG diameter of coil , why i use SWG 38 (0.1520mm)  and SWG 35 (0.2130mm) for  bifilar coil.

Bedini SG Ratio  Trigger Coil / Power coil
         AWG 26 / AWG 23  =  0.4040 mm / 0.5740 mm = 0.7038

My Ratio :    SWG 38  / SWG 35 = 0.1520 mm / 0.2130 mm = 0.7136    (near to)   

The third coil, number of turn and diameter are free,  depend on the load u want put it.

If third coil generate/transform more voltage, maybe will burn your led.

With third coil , we can make high voltage gun

Note: DANGER ! : Please keep of your eye not stare on the led.
        Put a papertape on the "glass" of LED for safety.
