Fracturing Water Using High Frequency Electricity.

[hypersoniq]

I have an old Soundblaster Live! card in my aging lab PC. It has a front panel headphone jack that puts out very low power even at full volume. but it has a 1/4" input (just right for a guitar cable)
I have an RMS DMM that measured the frequency of a signal (program set for 923Hz and meter reads 925Hz)
not bad for a free signal generator! my limit is 20KHz due to the soundcard.

I would like to try testing this in a small plastic container (like a tic-tac box) and check it with no magnets, then another test with these 1"x1"x1/2" N50 NdFeB blocks I just got...

my meter measures freq to 2Mhz max so for now that's the limit of my experimentation....

making sure I got this right, frequencies of interest so far (that I am currently capable of working with)
923Hz
600Hz
software lets you choose from square wave, sine wave, triangle wave... should be set for square waves? if so, what duty cycle? (default is 50% max is 99%)

For some good information on thyristors go to http://en.wikipedia.org

I think you will find what you need there. Just put thyristor in the search box.

OK. i have installed the new transistor, this one can drive 400v and 12 amp, i needed to modify the control box a little to, removed the N MOS, and installed a OPTO to drive the new
transistor.

I don't plan to use all the power (240v and 10 Amp) more than some sec, just to let me messure the volt and AMP's on the pipe, in different freq. its a little scary to use 240v and water brrrr

The purpose of this experiment is to test if i can find some fluctuation in the volt in different freq. then try to lover the volt...

Like hunting av mosquito with a shootgun... hopfully i hit something...

Hi TMGhost,

Without a heatsink on your transistor and running 10 amps (you didn't say the expected voltage drop across the transistor), I'm betting that baby will cook before you can get a stable reading on a digital multimeter.
Good luck and please take care!

About transistor ... It is in switching mod so u can add 50 % more power, coz it working only "open time" time when current passes junction. My suggestion is to test with smaller current first. If u will exceed maximum power first thing u will notice is momentary temperature increment and if u will keep it going then it will just burn inside. So test with lower currents first for longer period of time, you may want to know temperature inside is much higher so u need to run it for longer time to notice changes. depends on material .. so far as i know 300 c is max but im not sure. 

BTW how u made inductor ? how many turns and so on. Maybe you can gimme some tutorial sites ? Or you just used oscilloscope by "try & error" technique. So far as i know induction element .. as smoothing element depends on voltage and current. so if u will change input u will get changes in output.
