Joule Thief

[crowclaw]

I had something happen that surprised me tonight.
I have a cfl across the secondary wires of my jt secondary.
It lights... ok normal.
Then I added a bulb that is screwed into a bulb socket with wires, and I added that in series with the cfl. so they are both across the secondary and in series with each other.
The cfl goes on, but the other bulb does not.
How is that possible?
I expected that if the juice doesn't pass through the second bulb, then the first one wouldn't light either.
Is this normal?

Thanks,

jeanna

@ jeanna
Your series circuit comprises of a low resistance bulb fillament and a CFL (which requires a high voltage pulse to ionise the gas between it's electrodes) It's resistance to any current flow is very high so the current flow is insignificant. The filament is just seen as a straight piece of wire in this high resistance circuit. Hope this helps.

@ jeanna

sure...

0.74mH =  9 turns.

Thanks.

your filiment bulb serves the same use as my loaded cap trick .... 

forces your jt to pump harded

just like the song ... 

better faster harder stronger takes the ladys extra longer ... 

cept J  course !

i mesure dc and ac from my coils  1 diode in place ...  must be ac or my meter wouldnt read it .. and must be dc ... or my meter wouldnt read it ...

no bridge ...

fact i can read much smaller amounts on my meter no diode .... 

: ) 

i know the diff between oscolating ac and dc and radient ...  and bla bla bla ..

lol

1 more fact if i put magic maker all togather agin : )

i can pull all i said and more from it

including neg and pos .. osc ac and dc ac dc radient ... 

all at 1 time .. 

peace .. 

single aa or cap if i so desire to run both..

ya right thats only off the back side ...  now i need to make it do something on top all that to be usefull ...

This guy's nonsensical prattle grows tiresome.

EDIT:  @IST, I was not talking about your prose, but user, "qweqwe," in the links above.  Sorry about any misunderstanding.

i did find years ago how rude you were ... 

never liked it ...  : )

here we are ..

care to talk bout your coil ? 


perhaps we have growen since then ?

w

how ever i like your coil...  and  i  dont think many know how it operates.. if you felt like speaking bout it .. im all ears ...

if not ...  well guess i can play ..it too...

wasent it a coat hanger 3 stack tpu ...  otto on steel ... ?   viboratory induction genny as well as magnetic currents ... 

kinda think it was ... 

i was cleaning the lab all day yesterday ...  still not done ... yikes ...  how ever i pulled out THE 6 MOT ...

it now rests on table #4   to be driven from the wobbly 404 ....  through the 12dc cap full pulser then the construction caution light .. then the mot to the 6 mot board ... 

and i got me another 1000 ways yet ...

thank you !
