UZ,
This is an indication of looow permeability too high flux. they are opposite low perm=hi flux
you need 11,000u anyway.
See what he says.

It is disappointing, but it is good for learning the parameters.
I was really lucky at first because everything I touched worked (normal for me but really NOT normal for me in electronics!) I was very encouraged, and only later did I run into expensive duds.

I am glad you did this. Carry on!

edit,--- I missed the first post.

Maybe he will appreciate it if you do not go when you are sick.
This will give you a speck of time to wind a few more.
There is no point in going too fast at this point.
Make a few, learn then order 2 dozen, but you don't want to get stuck with them.

Be well,

I guess I will try again tomorrow.
I got some sparks at the wire junction with the charged cap, but not enough to turn on the unmodified cfl or the filament bulb.
The funny thing is that with the diode and cap, I was also not getting the cfl to light by touching it as I had easily done before.
OK tomorrow is another day!
I only have 2 high voltage ceramic caps a 105 which is 1uF and a 581 which is 580 picoF and way to small.
I have something I cannot count that is 1000v from a cfl. Maybe I will remove that and try it tomorrow.

fyi:
The safe set up is nice.
I am using that ceramic bulb base which is wired for house current.
I clip the + end of that bulb to the + end of the cap and the reverse, then I can put the battery in.
When It didn't work, I could safely remove and only touch just the one side of the secondary so the cap could charge, observe the spark, but not get zapped.

Too bad it didn't light.
Maybe I should try this in reverse since I always get these things in backwards??

I  show boards i made some small rings bridges diodes caps ...  i found the old cam cap motor thing board ... 

ENJOY!

It is pretty risky.

Maybe you should get a battery from the A store first and see.
In any case, your battery will most likely be fine, but DO NOT have your computer any where near it when you are doing this OK?

Last year when we were first playing with the HV from the fuji cameras, several of lost our computers or HD's. It could have been coincidence, of course (, but it sure was a coincidence!)

If we don't hear from you for 6 weeks, we will wonder what happened.

Thanks Jeanna for response. I have never opened my computer battery. When putting out the battery does one loose data?
Gagdet if you have a board please I would like one.
Thanks

Try reversing diode. Your caps are probably too small, but large caps are dangerous. You should buy a CK06 that is 0.1 uF (or two that are 0.22 uF and put them in series to get higher voltage rating). I was able to light the Christmas tree bulb with 0.22 uF charged to 400 volts. You should be able to light one with 0.1 uF charged to 1000 volts (if the cap does not short out). It is only going to blink, it will not stay lit. Once you can do that safely, then you can work you way up to larger caps in small steps.
