Joule Thief

A couple of pix
These show the safe way I am doing this.
I will not grab the ends because it is all so stable.
the diode and where the cap and stripe are.
The scope showing over 1000v, 2.39khz
That it is quite a capable jtc for a cfl of 10-20w size... more probably.

I am afraid these components won't do, or something.
They are both rated for 1000v which means plenty.
They shut it right down. Close it off.

@all, thanks for your help,

Prompt what кандинсаÑ,ор it was used in this circuit, give the exact data?

What to put polar or not polar?

Attached is what you should have except with a larger capacitor and the bulb would go where the voltmeter is after the capacitor is charged (only takes several seconds).

100uF........?
220pF........?


This circuit works?
In advance thanks !

@zhak

if i recall correctly jeanna's circuit used a 1uF not polar capacitor.

xee's circuit uses a not polar capacitor also, 200uf.

This is not a specific circuit. It is an example meant to show how I measure the output voltage of the pickup coil. Any type of capacitor can be use but the voltage rating of the capacitor must be as high as the output voltage of the pickup coil. I use ceramic capacitors that are not polarized.

EDIT: I use capacitor values of 100 pF to 1000 pF for measuring voltage.

approximately -
On how many capacitors volt V? 
100uF........?
220pF........?
