Building DS Plasma Globe

[Paul-R]

You should remember that you are dealing with an LR circuit driven by an alternating driver source.

Tegherfore, there will be a resonant frequency. You need to run at that frequency.

Paul thanks for the input,
I am only partially confident that the place I am taking the Freq reading is correct, it is around 15.1 khz. Oh, please forgive my arrogance, As we all know many EE, et al professional and experimenters have tried to accomplish what I am with little to no success. I am not too concerned with the resonance just yet. time will tell if that is what I eventually get to.  That being said I am only somewhat competent with testing and parts arraignment.
I really do not have a clue as to what I am really doing with this device.
Sure I am getting results but for me to explain what I have is only by trial and error.
This thing is really getting dangerous. I took another jolt from this thing today I got it on video and oochi wa wa 700 V well over that in amperes.
I will post that video when I get calmed down.......
I changed the circuit and the caps charge two to three times faster.  400V in 10 to 12 sec.

I must put more things together to make it safer and safer..
This thing is starting to get my respect! I have picked up many bad habits handling wires before I made the circuit so now at this stage, I cannot afford to get sloppy....
I must slow down and be conscientious about this being a power supply unit!!!!!!!

Please everyone this is my most sincere direction about this circuit be careful!

Here is the video of the new circuit. it is working ok.
I will try to clean up my act and not get shocked again.

@ Mags and wilbe,
I am not ignoring you guys I am dumber than both of you guys.
I can't make any sort of light light.
I have done a bunch of looking on utube and the instructables before now and picked up some incites I do not want to try. The one guy on tube had a long list of comments where  I learned a bunch of stuff that will melt a hole in the glass, things like that I do not want to try. just putting your finger on the globe when it is in high resonance will cause it to get warm.
There also is the fact my wife told me I was going to ruin it.
She is funny, I don't abuse it or anything, but she had to say that. Like she wanted to put some gri gri on my project or jinx it. I have to be carefull not to break my PWM plasma globe.

Thanks guys for the input.

The reading I took today before the new circuit design came out like this...
From the L-2 through the circuit;
The time it takes to get voltages of 100, 200, and 300 are as followes;
Bottom of L-2 = 3, 6, and 19 sec.
Top of L-2 = 3, 8, and 22 sec.
I realize I will need to accomplish this at a much faster rate when this thing is pulsing the IT but OK for now.
I will take the readings on the new circuit tomarrow to see if these charging rates are faster.

I am not too concerned with the resonance just yet.

Its OK to feel your way in the dark. We all do this. But most stuff to do with Tesla, including Don Smith, needs resonance to get results. The circuit needs to be tuned.

I wonder if you play the guitar? If you have a guitar that is properly in tune, then when you play the lowest 6th string, the highest first string will also sound off. (Best noticed with strings 2,3,4, and 5 damped). If the guitar is not properly tuned, then when the low string is plucked, the top one will be silent.
