@all

I see soon , a gas powered generator running on a hho cell from a joule thief on a earth battery ...

welcome back gadget !

@ Neptune01,
Welcome to the Joule Thief forum.

I need some help and advice since I am unable to get this working.
Could someone please verify and correct me where I am wrong.

Thanks
J

When you are first learning the Joule Thief, this circuit is about the best there is to learn on.

The resistor to the base of the transistor is generally 1k (1,000) ohms at a 1/4 watt (its quite small in size phisically) for the circuit you posted.

The 5 watter would fry the transistor base, too much current would be alowed to pass.

Try a white LED between the Collector and the emitter, it should light.
If it dosent light, turn it around.

Other transistors to try would be the 2N2222 or any general NPN type.

When you get some success, swap the BC548 for a 2N3055

Happy JT ing. ;D

i have been rechargeing the 4.5v 2.1 ah battery  my supply aa went dead over night .. so i plunked in another week battery this morn ..  yep sure is rechargeing ... but this is a slow process 

i started at 4.1v in it im up to 4.33 now but i bet that battery pack could power this charger quite a few days ....

so i tryed a a sealed battery 12vdc 3.6 ah  and it was 7.1v when i hooked it up

i must say it charges MUCH  faster than the alikline 4.5v 2.1ah  its only been on like 5 min im already up to 7.41 vdc in my battery ... 

ill let it charge while i build my next toy ... 

To understand the action of the local condenser E in fig.2 let a single discharge be first considered. the discharge has 2 paths offered~~ one to the condenser E the other through the part L of the working circuit C. The part L  however  by virtue of its self induction  offers a strong opposition to such a sudden discharge  wile the condenser on the other hand offers no such opposition ......TESLA..

THE !STORE IS UP AND RUNNING ...  WE ARE TAKEING ORDERS ..  NOW ..   ISTEAM.CA   AND WE CAN AND WILL BUILD CUSTOM COILS ...  OF   LARGER  OUTPUT ...

CAN YOU SAY GOOD BYE TO YESTERDAY?!?!?!?!
