weren't you once talking about studying agriculture or something like that? anyway there are pll ic's, i have found a nice website on this topic, which i included a download of, because it is not online anymore. (see attachment) the state-of-art way would of course be a microcontroller.
edit: i found a link on archive.org: http://web.archive.org/web/20080214161414/http://www.uoguelph.ca/~antoon/gadgets/pll/pll.html

thanks stevie i'll read through the topic you mentioned where unclefester posted in regularly.
also i finished building the "cell" today, i begin to wonder if the inventors ever built this thing, 5mm is a large gap for an electrical field but a small gap to see if there's any production going on. my high voltage wire arrived too. will post some photos soon.

Ya I was studying in construction plan designing

But I dropped that , too boring .

Im better in electronics , and I think it suits my passion better lol .

Ok Dankie.
Thats the way to go. Just followe your hart and passion. Then only, you can be succesfull.

Well my cell is assembled and when filled with water it has a capacitance of ~500pF (0,5nF), depending on which electrodes i use (from 480 with the largest spacing to 540 with the smallest). With a little light it's possible to look through the side-walls and see exactly what's going on. Will be awesome if the whole thing works.

I put  water in for half an hour, seems to be water-proof except for one side, where slowly tiny amounts of water pour out of the container into the plastic sheet - electrode gap. It's not much, but water at a high voltage electrode doesn't seem like the best thing to me. Unfortunately it's all sealed with plastic glue, cannot change it without destroying.
Electronics will be assembled when the parts arrive here ..

For a simple test a 555 may be adequate,  but implementing any kind of current control, feedback etc will be more than challenging.  I would set the 555 frequency at 15 Khz or so and the pulse width at 1 us. Then gradually increase  the pulse width  while looking at a scope reading of primary current.  The primary current signal should look similar to what you see in the Spice simulation. Operation should be in discontinuous mode,  meaning the current should rise to Ipeak and then fall to zero, with some dead time in between current pulses.  A CMOS  555 cannot adequately drive a Power Mosfet  so some kind of driver circuit will be needed.  A  non CMOS   555 can source and sink about 200 ma,  and while not ideal, should be able to directly drive a FET.
Skipped this one too ;)
I'm mainly using my mikrocontroller pwm to give the pulsed dc. Driver circuits are included in the patent, also descriptions of duty cycle and frequency range.

skipped a party for this yesterday  ;)
I built a circuit that matches the description in the patent, it's two pwm's with gating where the gating time is set by a 555 and the actual frequency is adjustable by my pwm box which i made. Also you can see they are turned on and of in a flip-flop style, with a little pause between the pulses. photos done with mobile phone, quality sucks.

one channel is the upper pulses, the second the lower:

pwm box powered by an atmega8 mikrocontroller:

the actual circuit on a breadboard:

and last but not least the cell, i know it looks like a piece of shit, i'm not exactly a skilled craftsman, there's also already some aluminum-oxide because of the few water drops. :(

thats a nice clean layout there .

Nice box too.

finished the driver circuit, identified the pins of my two flyback transformers. just have to cut and connect the high voltage cable and hope that everything works ;)
the aluminum oxide layer on my aluminum foil got pretty large. i hope it is conducting now.. and of course after some time water will get through it, probably short out the whole thing.. i'll see how this can be solved.

my plan to disassemble the thing went horribly wrong. don't use pattex plastic extreme glue if you want to get something loose again  ;D

anyway, have to order the parts again. now i know why research costs are so high if half of the stuff gets destroyed in the process..

Thats that dark site of the force...i mean, hobby..

alright, i got my new parts,assembled it. fixed it around 20 times so that it wont leak and then finished the circuit.
i got high voltage at ~15W input. 15Volts / 1 Amp. Every minute or so the capacitor would discharge/spark through the air, i have to isolate the connector panels better. but anyway, i should have had over 10.000Volts, because the gap it sparked over was around 1cm. No gas...

In the future I'll try to regulate the voltage to the 18V needed for Full HV with the flybacks, well i'll see. i also cannot know if both sides charge right, because i do not own a hv probe. i'll play around with voltage and frequency tomorrow.

so far disappointing
