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

Materials.
you will need:
toroid core(ferrite)
2n3904(sometimes others work too)
512ohom resistor
winding wire(0.15mm approx)
0.2-4mm as well!
neon glow lamp (i used maplin rx70)
time!

Wind the Hv Windings.
Get your 0.15mm wire and wind at least 85 turns
through the middle of your toroid like the pic.

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.
