ok guys ...

easy way to tell if your doing this correctly ...




first i did was solder the switch...

so now it turns on soon as you put the battery there ... i did this after i removed the flash and the big cap ...

then i took a neon ... it has 2 identical prongs inside it ...  so i checked to see if it would light it did but ONLY 1 SIDE OF THE PRONGS..

ok no problem ... it was fairly bright but it would not light a cfl ...

so i just bridged the diode next .. i checked agin with the neon ...  now both prongs light.....  ok ...  so now i have it flowing both ways...  i have not checked the cfl

i still have not removed the 100 ohm resistor ..

so i would expect it will light the cfl dimly now ...

still my led on the board is not lit

ist!

i get 0 light in a cfl.....    funny cuz my OTHER BOARDS LIGHT IT NO PROBLEM WITH OUT ANY MODS....  JUST NOT FULL BRIGHT!!!!!

got to be the bulbs..... 

sounds like you get the bad stuff down there gadget ...

it was putting out 260vac ....   un loaded 67 vac loaded ....  not near enough ....  the others put out 380 or so un modded and it is dimm

not near your brightness...   

must be the bulb ...      what is your modded aaa fugi putting out in voltage gadget??

@ Gadget

Here's a pic of the Fuji board with the D1960 transistor, it barely lights the neon at the output.  I cut off the 68pf cap lead which you see hanging in the pic (point 1) and the diode short is clearly visible (point 3), also notice the "Achilles heel" spot is not touching so no short there (point 4).

I took a reading of the pot after taking the pic and it's reading 0.68 K ohms (point 2), that's where the neon is brightest but as you can see it's nowhere near really bright.  I'll solder the 68pf cap back in but it really wasn't doing anything for the brightness of the neon.

neon nice and bright no cfl light ??

@all

I know about zener diodes but not that much , so i wonder if you send lets say a 60 volts in a 6 volts zener , yes you get 6 volt out but what would happen to amps.?

Anyone has idea?

[innovation_station]

where will we find zener diodes... to play with ?

i discovered the glass diode in the fugi is 1.5meg ohm  ...     

now i was looking for 1 of thease a while ago.... 

on my mk2 supply board i used the same diode on the super cap as the bridges ... i should replace those diodes with the tiny glass one on the fugi board ..

my cap would fill higher ...   and most likely charge the aa batteries faster...

that is what i think ...

ist

what is the diode in the sunbeam cfl unit ??  a zenier?

so i get another retarted idea lol

so i have thease 3 chaseing leds from ramma ... well  add 3  jts to them inplace of the leds...  and a few caps that fire when full

with the full caps that fire on there own   do it agin only with 100vdc     use what comes back as out put ... 


now you got your tpu ...

well almost ..
