Joule Thief

[kooler]

@All,

Is there anybody who has a good Joule Thief circuit for me???
I need a JT which can power up 1, 2 or 3 superflux leds from a single battery.
Amp draw is less important then brightness!!!
Leds need to be at least 80% bright.

Thanks

see if that works for you.. that 10mm led he is using isn't a regular 10mm it pulls 100ma from 3.4 volts..
hope this helps..

Thanks for the link, looks very promising.
Do you know the amp draw of the circuit when driving the led?
This would meet my needs when i parallel the 3 leds up.

I finished my solar garden light today.
Thank you Kooler for your help.
I will post the solar circuit tonight or tomorrow, i made my own circuit in stead of using lidmotors circuit.
I have a new laptop and need to install software to shrink the pictures first.
Also i will take a tew foto's tonight (dark action foto's).

He may be a physics professor but he does not seem to understand electronic circuits. He appears to be measuring the instantaneous output power produced by the collapsing magnetic field of the output coil against the simultaneous input power. This is indeed over unity for an instant but only because the energy stored in the coil over a long part of the cycle is being released in a very short time at that point in the cycle. If the "energy in" over a complete cycle is compared to the "energy out" over a complete cycle the efficiency is less than 50%. If you take a car battery with a trickle charger and let it charge for 24 hours and then put a 1 ohm resistor on the battery and measure the input to output power it will also be over unity for a short time. But that is not a true measurement of over unity because it is using stored energy.
