Thanks very much for the reply... Just to tell you -> I'm 14 years old  and I am a "school kid" (sounds as though you think I'm a teacher)  ;D ;D ;D... Perhaps my name should have been ScienceBoy not ScienceMan ha ha... But anyway thats besides the point...

Thanks a whole lot for those instructions and like I said earlier, I'm gonna make the JT this weekend and post results and photo's etc... Thanks again :)

Thank you for the warm welcome! I do have another question that is not related to the fuji circut that perhaps you or someone else might be of some help. I built the JT from the instruction's at evilmadscientist.com and I got all my parts from radioshack. Right now I am simply connecting LEDS to the main one in the circuit and there all in parallel. I have got around 15 LEDS running just fine. And I am sure I could add at-least 15 more. I think most of the people on this forum put there's in series, is there a reason for this?

The more I read in the forum the more I think I am missing something. Should there be a diffrent coil then the one the LED's are connecting too? My coil is only 6 turns or a 3/3.

I noticed on here that some coils have way more turns then mine. I also completely removed the resistor once I added more leds to the main circut. And my mA drawn went down slightly.

Again thank you for the warm welcome!

Take Care!

Welcome , and yes try something put one more coil on it and connect your led on it , they will light , 1 turn may be enough to light all your led , now if you can light all the led you have parallel on it , how many 1 turn coil can you put on your toroid
And how many led can you put on those , the answer is to many , for the money a have.

I only connect leds in series to check voltage , but in parallel is the way to go.

Edit @all also longer jt coil lowers battery draw.
