Also, in the link i posted, doesn't the circuit posted differs from what he did?
Yes it is the same 5 pin transformer. The pins are 1,2,3 for the 3 pins windings and 4,5 for the two pins windings while in the image the pins are 1,2 for the two pins windings and 3,4,5 for the 4 pins. So, should the transistor base be soldered into the first pin from the left of the 2 pins side, like the guy did, or into the first pin in the 3 pin side, like the image with electric components symbols? Got it?
I'll see if the transistor and diode are working, but i don't know how to see if the transformer is...
No, there's no numbers nexto to the pins. All i was saying was in the two pictures i posted in my first post, one is the circuit schematics and the other one is the "real" components connected. The two images have different pins number and therefore different connections of the elements.
For example: the transistor base is connected to one of the three pins in the schematics, while in the components image, the transistor base is connected to one of the two pins.
BUT, considering that what the guy showed in his photos is the right circuit, mine still doesn't works. I'm getting ~1V output even without resistors (tryied with an open circuit).
With only a 1.5V battery, what lights the LED? Most LEDs have a Vf > 1.5V???
