The Information is Correct for this Schematic Alone . Jeanna Is not using this Configuration ! OK so leave it as is and Lable is Fusionchip/with Jeanna Secondary . Number 2   LPJT   . Ok when Jeanna Gets the new torroid and decides to wind one like this she can put her measurments ok . Thank You Jesus . You get those part Yet ?

I have only received @pirate's fuji circuit with a slide switch.

@pirate
I tried it and it is the same as the one I made with the first neon bulb. The transformer is six legs but one leg has nothing on it, it is only a pin inserted on the plastic.
But at least I have it! Thank you @pirate.

Nice work :)Ok, so that's this one? Quote: "There Is a 220 ohm resistor on the bas I replaced it with a small 10k pot and added a cap on the circuit across the last leg of resistor to coil ."
Sorry to start bugging you but the pics are very unclear, could you perhaps draw a little schematic if you have the time?
Thanks.

Yeah that sure sounds good!
Keep up the good work!

Best regards,
Koen

Hi Thanks . No i wont be Drawing up a Circuit but if you have a Fugi board all you do is short out the Diode . Hook your lamp up to where the cap was .. look at the transformer on the component side. there is a small resistor there between the transistor . remove it and put your pot there or i have found that 3000 ohms works good , . Next turn the board over . trace the resistor to the coil connections . this  is where the 68pf cap is soldered . Thats It ! I'll post a Clearer picture of the back in a little while . !! EDIT ITS POSTED CLearer  . Also when using the resistor ion my third unit i built today i added a "Start"Switch . Its a  small momentary pust to close connected across the resistor if your CLf or tube Will not light up bright to start with . When the batt reaches 1.1 volts or lower this is needed  or either a variable. BTW My 13 watt CLF is still lit  Batt is 1.17 .. I will let it run for another two hours then recharge the battery . . Number two has been running since 8 this morning CLF 45 watt thats 7 hours so far on that one  ) Much Better . I bet this will light 400 leds for a LONG time !

@ All

Congratulations to all on your concerted efforts on this thread.

Been watching this thread for awhile and noticed that there are a lot of variations on the circuits so here's one without electronics for you all.

This is using a joke buzzer that gives you quite a jolt btw, I used it to light an NE2 bulb.  I took out the 3 button cells and ran it from a 1.2 V AA battery, I even had it going through a bridge rectifier which would charge a capacitor to over 100 VDC then another NE2 across that cap would bleed the charge back down to 82 VDC and start all over again.

I didn't try lighting LED's because of the high voltage

Nice . I wonder if your joy buzzer will power a MOT

Nice . I wonder if your joy buzzer will power a MOT 

oh  ...   lol    i know it does ...  and when IST'S NEOZAP  is at play it gets wild ....

cheers .... 

mag amps are almost done ...  pics soon

ist

if this is correct i will build 4 more EXACTLY THE SAME ... but i will hook 4 up parelell and 4 up serial   gonna need a bit of help with that ...



also i matched primary to secondary  all 22 gage wire  1/3 pri 2/3 secondary    14 turns primary ...  28 turns secondary

so what i was thinking with this unit is ...   power  this with a single jt ... but hook it up with the jt     meaning include this in that curcuit just throw it in line with it   2 cores are for  pulse coil and 2 for trigger coil ... 


think it will work ?

so now i will wind a standard jt to power this unit ...   i will make it 28 turns bifillar 22 gage

if it works out proper it should be 1to1 mass tuned

@ All
ok the first Fugi lighting  13 watt CFL DIED at 1.16 volts and ran for 12 and a half hours !

I can get it to go more by adjusting the pot but the current draw goes up to about 30 ma . I will put a fresh battery in it tonight .. I think it would run a string of LEDS much longer . Some one is going to have to drag out there Christmas Lights (Pirate ) and see Mine are packed up and unreachable until Christmas .. # 2 is running fine since 8 am this morning !..
I have a few different camera boards like the Kodak and some i got from gold mine(unknown ) . i'll play with them tonight and see if i can boost there performance . 
For those that didn't read the post a few pages back  have a look Back at them and you will know what i am talking about .L8r
