Beautiful, IST.
If that doesn't light a cfl immediately I want to know.
Please follow up with performance.
It is as important to know which designs do not work as those which do.

I think Ali is amazing. I especially like the way up is in all directions.
At the very least, it means she has had open minded teachers, and a good start.
Thanks for showing.

Let us know about this new toroid, please.
You gave this

primary coil on this wind is 2' trigger is 6" secondary / pickup 18'

Details like
#turns you gave 2T,6T, so how many in the pickup? That would be xxT
Kind of transistor
Resistance at the base
Input and output voltages.
Then we can make sense of the rest of your information...please.

im working on it ...

i was gonna try the 3055 tin cans ..

but i cant seam to find one that works ...

im playing with it now .. i will make videos  once it is running ..

forgive me ..  it has been a while since i did any  hooking up ..

and i hope to locate more transistors .. 

w

turns on pickup are 54 so 27 each way ..

got it running the way it is .. im useing a 4401 
at 13.36 khz it is vhf .. off my 20mhz scope .. 100v + peek to peek ..

i can tune to much larger peeks .. but freq decreases ..

im not happy with this unit ..  i think i need finer gage wire .. maybe as a jt ..
but i will keep playing with it for now

@ kooler

I bought a new ignition coil and tried it in the SCR circuit. Results attached (not very good).

@xee2

i tried using zeners and diacs , a resistor ... i blow more scr's with the zeners ... so i stuck using the neons right now.. (cheaper to fine tune with.. )
the diac's dont seem to be stable enough.. always tripping before the volts get it
since my magic transformer blew.. i been using jeanna's toroid setup 3.38 with 300 turns
but i have to use a brigde in front of the cap before it charges... weird..
even wit a 0.047uf cap i can make the filiment burn in a 120v 4watt bulb (nite lite)
but keep in mind i am dumping the cap at 232-237 volts.. according to my meter hooked to the cap...
if it wasn't so cold in my cellar i would do more testing.. and another video..
my wife won't let me play with stuff like this or solder in the house
she sees a spark or hears the toroid hissing...
she lays the law down..!!

@kooler

You made my day the Wife bid was so funny...

But please say more about the magic transformer , we need to know , now that it is not working , you could even open it .

Why is it magic , coil design , coil mass , core design , core materiel .

I have seen your stuff since you joined , good work keep it up , the future is in green solution , old business model are moving to india or asia leaving us unemployed either we find new technologies to make and sell or we wait for a third world status .
