Intro: High Voltage Joule Thief!
this is how to make a high voltage joule thief!
the ones i made were 90 and 180v but the more
hv turns you do the higher the voltage(about 1v per turn)
this circuit runs best @2.4v-3v
Step 1: Materials.
you will need:
2n3904(sometimes others work too)
winding wire(0.15mm approx)
0.2-4mm as well!
neon glow lamp (i used maplin rx70)
Step 2: Wind the Hv Windings.
Get your 0.15mm wire and wind at least 85 turns
through the middle of your toroid like the pic.
Step 3: Wind the Low Voltage Windings.
twist the high voltage wires together to make winding easier
using your 0.2mm wire wind 5 turns and make a center tap
and then wind another 5 the center tap is the positive 2.4v.
Step 4: Put Together All the Parts.
now put all your parts together .
and test it!
