i didnt get an email notification to this posting so i neglected to reply asap. apologies
sorry too, i left off the negative on the emitter.and the 2nd resistor is 2.7 k
it works very well as it is on 1.5 volts. with 2 x 1.5 volt batteries its really really bright.
i have been trying to replicate this for 3 weeks now. ive spent about 30 hours all up trying every manner of things including winding 3 of my own coils (very difficult being so miniature).i even wound a trifilar toroidal coil which turned out to be an excellent charger but wont light the cfl. so that ones being kept for that project now
my problem is i dont know exactly how the original coils are wound. i can see the guage of the wiring from the protruding ends. .7mm for the cfl side and .5 for the 2 joule thief windings. i have every identical component except for the transformer .
good to hear Suchayo say about getting some current . how do i measure current ?
thats what i havent measured as i dont know how.
the only thing i have been concentrating on are the high voltages which i can produce without a problem.
i really really want to replicate my
working model and not destroy it to see its internal workings just yet as it may be the only one i ever get to work like this
How did you use the CFL, by using its filament or shorting the filament?
not sure i understood this. i just pulled it apart as per imhoteps video and twisted the 2 strands from each end together into a single wire, from each side of the cfle tube ends
