@XEE2 .. This is what i need ! . Do you mind if  i use it . What kind of Spark coil did you get ? Part # > I need a faster way to charge up that Bcap  . but i need it not to kill the battery so fast it can't be replenished .

Sorry. It will not help you. The total power out is less than out of just the JT. It just provides the power in high current pulses instead of a steady low current.

@ jeanna

The circuit provides a second stage for the JT that will provide high current pulses. These can be used to produce a much brighter light than could be produced from the JT alone. It will drive LEDs with amps instead of just milliamps. Think how much more light that can produce.

I am sleep deprived because of a neighbor's barking dog, and the thought of the noise from the sparks is really an uncomfortable one.
So,
I am wondering if the spark is needed why you cannot just use the 1kv-2kv wire ends from the big toroid secondary?

I guess I also didn't realize you had to have a break in the line to produce amps.??

@gadget,
I saw one of those at wallmart. Good find on the cigar box too.

I am not looking to diffuse the cfl.
A cfl is already diffuse.

It is the led that needs the diffuser.
All that brightness goes straight onto the ceiling.
An LED only brightens a room if it can be diffused.
Make sense?

I think it will work with high current pulses . . Maybe not But i could try to do your first stage and check it out . I need more than 5 ma i get now . It charges it but takes a day . If i had 20 ma it would cut the time considerable . I need to play with My Hv flyback and see if the cap will convert it first i guess . if it does then a spark gap charger with high current pulses might work , i think  ? no ? HAve any of yu tried to charge a 10f to 30 supercap up ? or just a plain electrolytic  ?

Sparks are just for testing.

hello
my next video was going to be of me running it thru a 1:1 toroid about 30 turns on both sides
it only shows a couple of volts on the meter but when you bridge into a cap you would be surprised

and yes i do like sparks and things that go boom!!
but, no the spark is to show the volts output that a normal meter can't read
if you seen the the microwave transformer... that spark has some current in it...
and yes it charges caps very fast.. its only 10 lbs.  hahaha

i do have other HV stuff but i don't think it is safe to show on u-tube ( it messes with my camera)

xee2
the only way i could get a toroid transformer to charge my cap fast enough i had to bridge it
and also i notice that larger triac and scr's steal from the output
