   Not sure if it will work in this setup but look at a zenier diode. They dont conduct until the rated voltage is reached. In this case it will reach it and dump and fall below again. Getting one for the voltage you need may be a pain. But then you might use a resistor in series with it to drop the voltage down.  Just that the spikes may cause havoc with it just not sure.

Thanks. I am going to need something like that soon. But this circuit continues to drain battery after it stops charging cap so someone has to switch off battery when neon comes on.

Well i don't see a problem there the circuit keeps the secondary alive .

But explain what you mean ?

@All,

I was reading up in a diode web site that there is a certain point where ordinary diodes will begin to loose performance at high voltages and very high hz, at AC for example when the cycle ends, the diode is still open, it hasnt shut fast enough, so when the next pulse comes through, some of the next pulse flows backwards before the diode can shut off.

So there seems to be a point when we will have to switch over to use high switching diodes.

This will give us all more pulse for the energy, at least it won't be waisted.

Got to do some more reading up on this first though.

No problem, just needs watching.

now maybe someone can try to enlighten me but if the neos are not moving and thus not inducing a current then what the heck are they doing thats assisting in lighting a light?

Is it true that a magnet must be moving to conduct a current?

Anyway, even if that is true.
The assist happened when I added the magnet, which means it was moving.
The light went on as soon as it snapped into place.
I was then able to remove the magnet and the light remained on and as bright as before.

It makes me wonder how much lower the voltage could have been; or if the  combo voltage frequency could have been much different.

@Jim,

thanks.

@All, I have a comment that belongs at the thread

It is about adding magnets to the earth.
