Second Stage Joule Thief Circuits

Congratulations!!!

I have a newbie question though.
Does that circuit needs to be connected to a computer to work?

I ask this because you said that it will use a software.

@nievesoliveras,

No.

The micro controller needs the software.
It is a plug and play circuit.

EDIT: OK, everything is working now. First test with bcap is ongoing. This test is only to see
if the feed back and discharge happens at the correct voltage levels. I have attached a zip
file containing the Eagle CAD (from www.cadsoft.de) design files, some gif files and the SW.

Hi Groundloop if the micro controller needs the software than as Jesus said one has to connect this to a computer and program it with a software as you're doing no?
Can one do this circuit analog or it would be very complicated?
Thanks

@guruji,

Yes you need a programmer to get the HEX file into the PIC16F88 micro controller.
One really simple and cheap controller can be built as described in the attached file.
The program can be downloaded here: http://www.qsl.net/dl4yhf/winpicpr.html
This program will control the attached drawing. You will need a serial port on
your computer. A USB to serial dongle will NOT work. You can also use one
of the many programmers found on the net.

Thank you Alex . It is Indeed a very nice but complex circuit . Only the Best and every project i ever saw from you was a master piece . .
On a side Note . I made an exact copy of the jt i made for you and guess what . It will not do the same thing??? It must be the transistor . This one works completely different with the exact same components . The only difference is component placement . There Must be some impedance  in the length of wires coming off the toroid .  Well you got the best one i have ever made and i don't think i will be able to make another on e BUT i will try to remember by the pictures and video I made and Maybe find the reason it put more out than in . When you get get see if i was right ? Definitely need your second opinion but as i said this one will not put more current out than in
