@ J ya!

it lit as it should ... if i was to fill the caps faster ...  it would run like in the wall  CONSTANT!

J  think about a HIGH RESISTANCE DIODE..... and low restance coil then in reverse ...

What is a high resistance diode?
And do I use one? or 2?

Which way should the stripe be on the secondary?
Does the cap go across?
Or is this with no cap?

thanks,

jeanna

i will work on my old circuit more soon.. so i can show the uses of it
the only way to do it safe is to (start out small)

I totally agree.

small output secondary and a cap three times larger than your output..

ah excellent!
this is the kind of thing I need!

and make sure you have a load on the scr at all times

Do you mean a neon? or a cfl?

i been trying to make it with less parts..

yeay!
...

and you don't need a ign coil to light small light bulbs
the ign coil is just a testing unit.. cause you can adjust it easier by looking at the spark for matching current and voltage going to the ign coil.. and after you tune it just right.. its time to put what ever you want on the output...

So, then I can use something in place of the ig coil but not the scr.??

I got these 2 scr's last week:
6Amp, 600v
15Amp,600v

I always want to do it myself, but like with the fuji ckt, I am willing to use something else first.
I have cam transformers but I also see there are nice transformers in the cfl bases... along with caps...

just don't put 700 turns on one of those 3.38 toroids and run the output from the unit in to it....
my table is metal and i found a bare spot.. haha

better the metal tabletop than grandma's hand embroidered tablecloth!

thank you,

why not a matched pair! ?



high and low resistance diodes .... 

all i used was cam out .. to a bridge after the cam diode to ac cap then through diode 1 side of cap ... to cfl and back to cap!


ill have to digg it out .... a  and make a new video explaining it ....  i will do it agin ...  not sure if i have any unmodded cfls left or not tho!

w

know why loggie said that ... ?    my plasma ball is audio driven!   lol   

i found wire to try for secondaries ...

alum
iron  garden wire .. coated
copper clad mig welding wire
rubber coated flex tie ...
magic twister ... twist tie roll 50'

Sorry,
I mean how do I know which kind is a hi resistance or low?
Also how do I recognize an AC cap from another kind?

all i used was cam out .. to a bridge after the cam diode to ac cap then through diode 1 side of cap ... to cfl and back to cap!


ill have to digg it out .... a  and make a new video explaining it ....  i will do it agin ...  not sure if i have any unmodded cfls left or not tho!

Does this mean you did these steps you just described using an UNmodified cfl??

A video would be great, but please remember to explain how to recognize the parts.

thank you,

an ac cap has 1 of thease on it ... 


a wing .... 

~ lol

my meter does diodes

crystal diodes are higher resistance thus gives higher voltage ...  lower resistance gives lower volts higher ma's

ist

yes un modded right out the pac... 

ill make a video when i can find the thing ...  i honestly have no idea where the orginal unit is ... 

im looking for it tho !
