hiiiiiiiiiiii.....i hav seen videos of joule thief......n i have made one from the site evil mad scientist...the basic joule thief circuit with transistor 3904 ,1 k resistor, 1 white led, ...n its working well...
i hav few questions,
1. i hav heard tht this circuit doubles the output voltage n current. but when i check in my circuit it comes the same as input voltage...n current is decreased.....???
2. how many led i can connect with this basic circuit....parallel or in series????
3. i hav seen in many video they connect a supercap in circuit ....can u plzzz tell me wht is the benefit of connecting a supercap? n how & where to connect supercap in circuit??
4. plzzz suggest me how to improve this basic circuit for more led approx 10 led??
5. in many videos i hav seen tht they provide high input like 3v and gets tremendous output voltage (in some videos approx 200v ) how they can do it....in this basic circuit how i can do this...??
is this circuit allow me to do tht???plzzz tell me how to do it???
and plzzz also tell me little bit abt inductors n its windings.....can more winding produce more voltage n current?????
plzzz help mee...
