Joule Thief

[gadgetmall]

Hi everybody,
Last week I dug my old iMac out of a box and as of today I have a working running debian linux system!!! Whew. well, a few things are running right. I still have challenges, but I am so pleased.

@Gadgetmail, I noticed, finally!, that you are using a PNP transistor. I bought a few of those a couple of years ago but never used them. Is there some reason that you use PNP? or is it because it is a germanium transistor that you use it?

Jeanna I have a newer Circuit look here . .202ma total .81 for 4 leds Its yours and Mine a hybrid http://www.overunity.com/index.php?topic=6123.msg154173#msg154173  Pm me for the SECRET !

@electricme . your right kc  kilo thousand cycles mc  mega million cycles American terminology Hertz European  same thing   . Pm me for the SeCRET !

Another great video. Thanks. Is the coil air core? If the fluorescent tube won't light with 1.5 volts try 3.0 volts. It looks like your components will take 3 volts and that would show how close you are (I think tube will light with 3 volts).

How many turns on coil?

Yes the coil is an aircore, although I use a axially magnetized cylindrical magnet and it fits perfect inside, and this can give you slight tuning capability and an audible feedback, like a speaker.  Cores seem to hinder the performance.  I tried a soft iron core, and it almost put it out.  I didn't count the number of turns, I wound about 9 layers of bifilar 22, and 24, and perhaps about 7 or 8 layers of a third coil of 22.  So you want a the 3rd coil to be longest to step up the voltage. The coil form I'm using is about 2" wide by 2/1/16".

Sorry about the last picture.
I hope this one is better.

I noticed on the second coil you can allso unhook it from the collector and just have the power and base hooked up.
And it still speeds up and puts more power out but when its all hooked up it puts out a lot more power.
But it allso uses a lot more to just have to try to find a sweet spot.

i resized your pic slayer

im gonna repost it

im gone to find bobbins 

ist!

@all

I promised to post a schematic today:
It is of my pulse motor running on a 7 bifilar turns joule thief.
