hey A and gals
i went into the foxhole  to nite and was looking at my 3rd and 4th stage .. the toroid with (700 turns) on it.. so sorry i chicken out..
what scares me.. is it doesn't show any A high voltage but if you touch it ..
man .. i'm turning into a pus..
well put it this way it will fire a 13watt unmodded cfl just like you put in a socket and run it constant
its only 300ma at 120v.. but it hurts like its 500v at 20 amps...lol...hahaha
sorry i wussy out on you guys at making a video..
my wife has done warned me..maybe soon, i refuse to not show you guys since all of you have help me .. with your different post
thanks
maybe soon

Did she make you take out a large life insurance policy?

Please be safe.

Please be careful, there is a lot of energy stored in the capacitors. To test to see if the caps are being charged, you can replace switch and filament bulb with a neon bulb. If the capacitors are being charged to over 100 volts the neon will light. If a fluorescent tube is used instead of the neon, it will light if the capacitors are charged to over 500 volts.

Well,let me understand this... that must mean you expect significant dampening in the circuit, because right now, I can light a cfl and a neon because there is 1kv, but it is flowing or pulsing and not pausing in a capacitor.
It is that pause that accumulates so much.

How much do you recon it takes to light a filament?

I am wondering if I have a bad batch of 4007's. since I have never-- ever had the expected results. Since I was new, I figured I was putting them in wrong, but now, this zero volts last night  makes me wonder. I have some 4001's and maybe I should use them.


I will let you know.
Not now, tomorrow.

thank you,
jeanna

@ jeanna

Does the neon or tube light when put across the capacitors with the diodes in series?

Your JT may need adjusting to work into the capacitors.

nah she just hates electricity.. ever since i built a jacobs ladder with a 6 volt battery and she was watching and said if i ever bring something like that in the house.. i was gone.. she also said that she hated my new hobby.. so i said its just small batterys.. it can't hurt no body...haha

i have trouble with diodes sometime.. but i stick a bridge in there and boom all the volts i need..
one of the reasons i show a bridge in all my videos.. is because i have trouble with the jt and diodes
so i use a bridge and then a cap

i bought a bunch of bridges from these people for 39 cent each once
1000v 4 amp
fast ship and billing
it's were i buy my scr's and sidac's

@ jeanna

I agree with kooler - a bridge will sometimes help (and seldom hurts) performance. Also eliminates having the diodes in backwards.
