those are the exact boards i have been useing keon1 ...

great ... 

i have been lighting 2 9w cfl from 2 aa's also with 1 wire ... at times   does not last long even with gm's mod.....


but you get 1 hell of a zap 

try it ... lol   make sure you hook it up as 1 wire ....  into the cfl and touch the cfl wire and the other power wire    ZAP!!   EVEN MORE BITE  THAN MY MOT ZAPS WITH A 12 V SUPPLY ...   BUT OF COURSE THAT IS IN 1 PUSH OF MY BUTTON ...  and the cam is open and closing the switch many more times ......    hence the bigger feel ...  in the ZAP .... 

ist!

just built mk1's 4 core magamp ...   wound EXACTLY AS SHOWEN AND IT DOES NOT WORK WORTH SH!T

i will re check the damm thing but so far junk......

im gonna build it with just a few turns to see if there is a diff ....  i hope so ...  sheesh    i the 1 i built i used 3' primaries and 6' secondaries

poor results ...  might be my fault ...   i dont know   i hope to find out it is ....

that looks like a fugi board keon1. IF YOU WANT 100% SUCCESS with  the FUGI  AA version only ! The way i FIX a FUGI board . is:::: tear the board out of the camera . i throw away everything including the film except the Board and battery .. VERY VERY SIMPLE MOD ..

STEP 1 : I KNOW THERE ARE VARIOUS WAYS TO DO THIS BUT THIS IS HOW I DO IT AND IT WORKS EVERY TIME  :::::::::::::::::::::::::::::::::REMOVE THE CAP and STROBE

STEP 2 : JUMP THE DIODE JUST SHORT IT DON'T CUT IT

STEP 3 : re place the 220 ohm resistor between the transformer and the little transistor with a 10 to 20 k pot

STEP 4: NOT Needed - future

STEP 5 : hook up your load to where the HV CAP WAS !!!

STEP 6 : SHORT OUT  The TWO SWITCH SOLDER PADS or PUT A SWITCH ON THEM .. you can cut the trigger fingers off (the thin long copper bars sticking off to the side )

thats it except adjust your current draw with an AMP meter in series with your battery to the lowest point you have usable light on you cfl /tube or what ever . this should be between 32-12 ma with  one battery 1.18 - 1.58  volts. thats it .NEVER RUN THIS BOARD WITH MORE THAN ONE BATTERY .ITS JUST NOT NEEDED you run it with either an  AA, AAA, watch battery (NOT LITHIUM 3volt ) C or D cell

these are the instructions to reduce the current . I can  tell you how to engage the other transformer but  it is  complicated .
IF YOU DO THIS JUST LIKE I SAID YOU WILL GET at least  10 to 12 hours of CFL light . and way more Juice left for 8 more hours to run at least 200 leds . the power reading was 220 volts when my cfl runs out of enuff voltage to fire it . Now i Know this works  because i am looking at two of them right now i put a recharged battery in them at 3 am this morning when i got up . they are still lit and its 2:45 pm  EdIt light went out here so 11 hours 45 minuets on 45 watt .. 15 watt lasted another  40 minuets . Approx 12.5 hours  same as yesterday ..
THE END

@ slayer007

did you wind one at a time

I used two separate single layer coils.

@ gadget.......

i have re built EVERY CAM CURCUIT I HAVE EVER USED ON ITS OWN BOARD I TOOK WHAT I NEEDED FROM THE CAMS AND RE BUILT THE THING

WITH ONLY THE REQUIRED PARTS.........


IST!


THANK YOU

i did this with your simple mod as well and it poorly lights mf cfl only for 15 min or so.......   hummmmmmm

sure i found the sweet spot ....  as the bulb gets brighter than falls out if i go to far ......

not near full brightness of the cfl .... why?... my cap says 68 it is a brown creamic a small one ....   my pot is 10k....  put this where the resistor should have gone ...

no diode ....  on the out ....  all else is the same is this YOUR MOD??  OR IS THERE SOMETHING IM MISSING....   tryed cap across battery many diffrent sizes ....  gets a tiny bit brighter ....   i could not notice a diffrance much between values of caps ......   tryed many ... from high uf  to low  uf ....   same results .... on the bulb   


i dont know im only useing a 9w cfl.....

THANK YOU

Its cool man . just giving the proper instruction for My MOD to the FUGI  . Ok .. your welcome .
