Description

Took an old tv apart, and decided to remake my joule thief by using the ferrite i got from the old tv

1 x 200 winds 0.5mm wire (you can always try any other kind of wire)
1 x 13 winds 1mm wire (you can always try any other kind of wire)
1 x ferrite core from old tv
1 x transistor S9015

the coil does not make any sound, i could not measure the amps cause it kept on saying 0, could be because my batt is getting empty of the multimeter

Tip: if this does not work reverse the connections of L1, and/or to start you need to touch the 2 leads of the LED
