Joule Thief

OK ist,
But see, I never get anything from a diode. I do not care which way it goes.
Last year mark said I needed a full bridge plus an additional diode on each end... that works. I could do that. That is what I will do if nothing else, but, I am not looking to vaporize the bulbs or myself. but I see this IS possible, and there is an underlying principle that tesla used and is in shreds in our modern system.

If I close the ends of the secondary it all stops.
I could probably make a spark bridge the gap at the end, but then that is what a cap might be able to do.
If I put a cap in parallel at the end (like the fiji cap) nothing happens because it needs to be influenced to go into the cap. enter the resistor... or diode.

When I made my astable multivibrator with 2 transistors etc, each cap had one resistor in parallel.

Maybe that is where the clue is.

Kooler, kapandanze, xee2, have all been able to light filament bulbs. It is close.

the unmodified cfl is highest priority too.

xee2,

These bulbs were lit with a 1 uF capacitor charged to 400 volts. This is the flash produced when connected to capacitor.

great, and how were they connected to the circuit or are you talking about kooler's circuit?

UN-MODIFIED?
I did buy those bulbs  after A. yeay!

Does the fuji board have an scr??

Really, I am asking if the caps should be parallel or series and if a resistor is put into this should it go parallel or series?
....
I appreciate your caring, unfortunately, out of frustration I might do something stupid like try some things anyway if I don't get an answer to this.

I will try the single diode on the cfl now.
Since the cfl  light already went on without any extra cap, this may not be so hard after all.

I do want the filament bulb secret, though. Didn't you vaporize the filaments in yours?

thank you,

Please read my updated post. I think the original suggestion was too dangerous.

I like that orb.

Please continue posting good coils, I like good coils!

And on another note; Those same coils look like those high precision DC motors ( compact DC squirrel cage ).

Please read my updated post. I think the original suggestion was too dangerous.

xee2,
It is not working at all.
I do not know how to make it accumulate.
If I put a cap across the secondary wires nothing happens.
Sometimes it seems to stop it.

I am sure you know what I mean because you were so pleased when kooler brought forth his circuit.

Have you ever been burned with a fuji camera?
I got stung with those a couple of times.
It was not even as bad as a horse fly bite.
I have been getting occasional little stings with the 1000v secondary as I hold the wires and touch various parts of light bulbs.
I am not too careful, because I have the experience that these secondary ends only sting less than a mosquito bite and they never swell or itch. I say ooo and that is all.

I promise to be careful because of all your cautions, but at the moment there is no accumulation and there is a way, but I do not know it.
scr will probably help, or is a scr necessary? no because the fuji does not use one.

thank you,

jeanna

i used a db107 bridge rectifier ...  perhaps your coil is not tuned for your diode .....

i used those big bridges  too  the mountable ones ....  it worked well  ...   i plunked this on after the cam transformer using the orignal diode ..   

then right into an ac 275v cap the yellow ones ...  non poiloized ...  then i put a diode off of it ..  drew pos from that diode ... and neg from the cap .....  and it went


zeeeiiiiiiipppp   bang zzzziiiippppp   bang  lol   

for a long time .... 

w

used a cheepie c battery! 

this is the unit ... 

i lit the un modded cfl with

but i un plugged the the microwave board ...  this  was a while ago...  maybe i didnt use a diode .. 

i cant remember now ...  i only built like 400 things since then ....

now take the bulb away ... and BANG A COIL!   

: )

YW

YOU MUST PORTECT THE SOURCE OR YOU BLOW IT UP ....

DIODE AND SPARK GAP ON INPUT ....  OF COIL YOUR GONNA BANG
LMAO!! 


naughty girl!   lol   ; )

you can ALSO CAP AT GAP ON INPUT of banger coil ...
