Parts
C4242 transistor = 1
Resistor
1k =1
3.3k =1
50k preset =1
1N4007 Diode =1
Capacitor
22uf (16v) =1
1uf (400v) =1
You can check dc 3v to 150v any led
One LED or series panel
Input voltage : 3.7v battery 5v usb power Input voltage
Output voltage : input volt 3.7v to out 100v-130v / input volt usb 5v to out 150v-200v
Verry safe output volt, use output capacitor 1uf - 4.7uf (400v)
No heat transistor Im use old computer psu transistor C4242, you can use [ 13007,D313,E13009,C3866,C5353 ] any transistor
Transformer winding : old two cfl bulb transformer Rewind one transformer copper wire remove to second transformer one pin connect (center tap) windinding all wire. turns 150 tap 150 simple winding.
