@ jeanna

Why don't you try to EXACTLY duplicate a circuit that was shown to work.

I thought I was. !!

OK so, I see the one that is also connected to the pos and I made a wire with a fork in it for something gadget did. I will see how that works.

It is a funny question you ask.

I will do my best. 


Was it a Hazens circuit you were making that worked?

I will be back.

Nope, didn't work.
I put the pos and the 1 side of the pick up on the one pin and
the other pickup wire on the other pin.

nothing.
I also tried the cfl which has been relieved of its case.
I also tried the 15w which is higher wattage but less than 20 of xee picture and happened to turn on more readily with my fuji.

Hey, anyone got a light?

And this one jt and electric guitar http://www.youtube.com/watch?v=aOz1pN8FROo

Thanks MK1
Thanks wilby for reminding me to look.

Maybe Larry Fishman should see that. hmmm

@all

i made a drawing of the stark , why because he uses bemf , but really because of his automatic neon switch on the triac when the cap reaches 80 volts.

I can see some easy improvement like removing the led , maybe finding a bulb that could act like the neon at 12 or 24 volt , choosing the right size cap get a fast enough discharge to pulse a core at 12 or 24 volts or even 80 volts.

We can charge caps with secondaries and bemf.

7watt fluoro tube
15 watt fluoro tube
no go on the cfl.

I needed some magnet action to make it turn on
Not the one that connects to pos, but just the pickup
and 100uF across battery rail
100nF (104k) across base resitor

yeay!!
