@stprue,
Very very nice.
congratulations!
OK so somehow you got your 2N3055 to start with those base and collector coils in the opposite  (normal) arrangement.

Hmm. It is what I expected, but did not find.

The restof it...
I know the pot is on the base resistor

What is the bridge doing and where is it?
And also please say where the caps are.
0.01pF Are you sure? and where is this one?
oh anyway, where are all of them.

Thank you.

Yes the 2N3055 will start up hooked up either way but if I switch it around it is like 2 or 3 hundred volts.

Th bridge only has the basic primary in it like Hazen1 would do.


The metalized cap might be .1pF I didn't have time to check on all my parts but it is either .01 or .1 at 400v

the one metalized cap is coming off the bridge and is on both the - and + ( be careful this will blow most LEDs)
the supercaps are hooked up on the input voltage side but are at the end and past the coil wires ++ and - for the emitter

I hope this helps but if not let me know and I will post some closeup pics for you tomorrow, as for now I need to sleep for my real job!

Good night!

The circuit  will not  shut  off  without disconnecting  the battery
The   LEDs  blink rapidly ...... the  meter reading the  battery  current  reads 0
The  battery  voltage is going up

I  was  not quite right about this .
The circuit does  turn off ......at least mostly off.
It may still be charging slowly ......with no tank  cap
WIth  a 1uF  tank cap  the array  glows  a little .
With  a 5uF cap  in the tank  the array flashes rapidly

hi all,

ima have try 2 make the AAA fuji circuit run but no luck still...

i try 2 follow the info from gadgetmall but i think hes info is only 4 the AA circuit.
the AAA circuit is abit different.

1 = remove HV & strobe...done...see pic
2 = jump the diode dont cut it...np...see pic...i hope thats the way 2 do it tho?
3 = replace 220ohm with a 10 to 20k pot....well i don have a 220ohm resistor on it...see pic.
maybe its the 102 one on this board?...maybe another 1?
4 = where 2 place pot...see number 3.
5 = np...can do that...

any help on this is much appriciated...

Peace!

Hello Free,

It looks close. Can you give me a reading from the leads where the cap was so I can know what your getting?

Thanks!

Wind it up!!!

That is some very nice work! I love the way it looks so perfect!

Nice job!

Finished product.

2 20W's and I know I can get more.

P.S. When I fist hooked this biggo up I was getting 879v but after messing with it I got what you see.  More then evough to have some fun with

Nice! Keep up the good work.
