Joule Thief

[gadgetmall]

@ 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.

Regards,
Paul

Goat .  that yellow wire with the + is hot and the one beside it is hot . ok then you need to measure the resistance acrosst the middle leg of your pot to the outside led  . get it close to 220

Latest  bridged version of my joule thief.

This is another one without a ferrite core, just a simple transformer - 16 / 26 windings - 16 for the current producing coil and 26 for the voltage collecting.  This one is turned on by a bridging the positive lead of the LED with the positive of the battery.

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??

I think its the Bulbs also . Must be different regulations in Ca. We got Ge bulbs i dont know if i have seen a sunbeam spiral .

withthe bulb off it put out 275 vac with it on only 170

@ Dr. Mk1 
      Hey thanks for the clipper tip . that baby put out on the magnetic field the piggy back bedini uses . another 110 volts to play with  ! . thank ya ! those coils are very Nice .. I had three of them and so My dog is Buried and i cut My own hair with Scissors sooooo.... hehehe ,,



@ all . Well its got to be the CL is Different in other countries  We are GE energy Smart Cfls . at least that is what is at the dollar store ,wallmart , big blue , kmart .. they work nice .. Maybe we can include them in a kit .. IF Customs don't get em .
