still dongt know who is this...

i think nobody understood my bad english hahaha

yea kinda hard to understand what youre saying.....

It seems like you said at certain frequencies with 12v pulsed dc square wave you get a graph that shows a 7hZ sinewave that doesnt cross zero but approaches zero.
At some frequency you pull a few amps and make some gas in a sealed single tube cell with some amount of KOH and polished electrodes.
It appears to absorb a 7hZ current from something other than your pulse frquency.....

Hard to make anything out of it....im glad you decided to use a little KOH and at least make some gas....to many people forget what the purpose of the circuit is....MAKE GAS :)
If we could all get the point of actually burnning the gas we would have some interesting things to discuss.

yes kind of i couldnt insert 7hz to the water it created a sine like wave that had only the positive side....on the current graph being ploted in real time...

i have some work to finish if i can i will make a video of it later...

also the water shakes maybe because of the bubbles.. being generated...

i was thinking that perhaqps this aberration on the cuurent measure can be also because of the bubbles..

i found that this false reading may not be what i expected.. it is maybe a probem of the labview module limitation of 14 samples per second....  so driving at this frequencyes low it canot avarage correctly and so gives this strange waves....
the module i use is ni9211 http://www.ni.com/datasheet/pdf/en/ds-197

but the water still shakes

My digital oscilloscope does very low frequency reading...

i will do a set of tests and film it so you can get more familiarized with what i´m doing and maybe more of you can understand what to do and do and maybe share back with us...

i really hope for all you that you can understand what i´m trying to say in the videos.. .i´ll do my best to be clear...

i will post all to my channel sebosfato  in youtube... hope it helps we start a good discussion,,, ,

That's coob Seb, I havent done anything since my wire arived....im glad i didnt use it yet for my inductors...according to most that have posted the  inductance of those washer drain pump coils are 150mH and they are wired in serries ....i need those as a salvage part in my efforts in using off the shelf parts in my quest....im really liking the thought of a mechanical oscillator now :)

i´m glad you started to get it! now i think its time to get and try!
