I'm interested in HV physics and two years ago I made my first HV circuit system. I used this system:

I want to study my self more HV physics and I'm going to do next summer something.
For example, I would like to do to this system:

That system would be very funny and interesting. But I think if I try to make other people stuff I will never learn anything. So should I make my own system? And how can I start to?

It would be nice if you can tell how you have started too?

That is usually how everyone starts! Get some experience, and learn why these circuits work, then design your own.

I started with an ignition coil and a 555 with some 2n3904's. I made a jacobs ladder and a small tesla coil, the obsession still lives...

i started with a 555 + hv transistor flyback driver driving a small audio xformer ^^. I still remember how i felt when i saw it working (putting a small 3mm spark

) It was dated back to 2003, 4 years since then...

Now i have learned power electronics, microcontroller programming, built an audio amp, some power supplyes, several flyback drivers, 1 coilgun pistol and a 3 stage halfbridge coilgun rifle, plus a levitation device and a sinusoidal function generator ranging from 0.1Hz to 17MHz. Now i am building a 3rd generation coilgun submachinegun (0.5-1 hz rate of fire) microcontroller controlled with programmable pulsetimes.

I started off with a Radio Shack "50-in-one" kit that I got for Christmas when I was six years old (in 1982). No, there were no "high" voltages involved. Still, by the time I had any clue what I was doing, many of the components on the board had been reduced to black, sooty stars

Of course, with high voltage, the potential exists (no pun intended), for *you* to be reduced to a black, sooty star on the floor of your garage

So if you plan on just "plunging in", the least reading you should do is the reading of the "Safety Sheet" on http://www.pupman.com, and any other safety tips you come across. And a fair measure of paranoia is always a good ingredient in any HV project. There is no shame in being afraid to touch things, no such thing as standing "too far back", etc.

I'm fairly contemplative when it comes to these kinds of projects, and generally like to feel as though I understand how things work before I built them. I usually find, after building them, that I *still* don't understand them, but that's another matter.

I read posts on the TCML for more than two years before building my first Tesla coil. That is obviously "the other end of the spectrum"

Somewhere in the middle is probably more enjoyable!

I started with a 20 in 1 radioshack kit about 4 years ago. my first HV epitrienance is a manualy triggered ignition coil driver. I was so happy that I could light up a HeNe laser and a xenon flashtube. I also could make small holes thru paper. I did that with a tishue and it caught on fire.

heh, i started with a self oscillating relay circuit and shocked myself with it. then i found out it was back emf...

Do you know any electronics? Pick up basic electronics and the rest should follow.

I started off with a ign coil and a 12vac transformer.
Just wire the two together and a nice arc 4mm max or so.
