You can post the template used for the pic programmer so we can replicate it in the meantime you get the other variables together.

@nievesoliveras
Just posted a similar answer above, but it's in dutch.
I have the diagram on paper for the PIC programmer i will scan it for you,
but have to work tomorrow so maybe i'll post it tomorrow but probably will be the day after then i know for sure i've got the time to post it for you and every-one else ofcourse.

   Hello, anyone feel free to answer my question, Thanks !!!

     If I had a Joule thief  putting out say... 60 Volts at around 10-25 mA's , I should be able to put
     10-15 LED's in series and all should light up nice and bright !!!

     Would that be correct ?  as long as each LED gets about 3v or so.

Maybe even twice as many.  Give it a try.  If the leds are in series it should not make all that much difference on the amp draw to add a few more lights.

By the way, the leds are not needing the whole 3 volts as they are only on for a very short time depending upon the transistor you are using.  Let us know what happens but, I would bet you can get a bunch of them pretty bright.

Also, how do you know what the output is?  If your meter reads 60 volts, well, due to the freq. and the limitations of your meter the real output is probably much higher anyway.  Very difficult to measure the output of these neat little circuits.

Hello guys,

Here is the scanned document (of the pic programmer) i promised.
I adjusted one thing tho and this is important!
The zener diode on the circuit (the 5.1 Volt) isn't a 5.1 volt but a 5.6 volt.
This is because of the diode right behind the zener it takes the voltage down and you want a voltage as close as possible to 5 volt so 5.6 volt is the closest!!!

Further the circuit is one on one.
I didn't build it as an ICSP but if you put a header where the socket is it is converted to an ICSP programmer (it's as easy as that).

If any of you guys want to see it in action look at my previous posts for the youtube link.
Enjoy.

Thanks for posting this but...

Holy crap!  This is well beyond my understanding of anything.  I have so much to learn.
