lol ok
If you need a basic schematic let me know.

While I work on that watch this videos if yo have not already .The end of this first video shows how to deliver Hydrogen  to the engine . Try and  watch it all if you have not . This is about straight Hydrogen but  you are also using Oxygen  which can be thought of as an enhancer . Does not matter the intake system should be setup the same way. This is just so much easier than for me to explain if you have not already done this.

EDIT

Try this it will help in production.
Then attach and drop it into the container :)
Oh and you don't need a real thick Plexiglas here.
I just made it thick so you can see it.If the fit is abit to tight  just bevel
the edges with a sander.

Frequency,amps and voltage control
All my S-Cells use controllable PWMs  . The large ones are Kurtis controllers
that have been moded .But the 48330 ESC Speed Control is my fav
this is  mid volts,big amp, programmable controller .
http://robotcombat.com/marketplace_speedcontrollers.html

My Cells are made in a specific way
for resonance. This is why I dont tell people to buy these
type controllers . They might not work on there cell design as the design itself can be the problem.Not all Cells will work in frequency .So it is best to experiment in a small cell with a little 40$ PWM  to start out. There are many thing you can do to tune the cell and signs that you learn  when the cell responds to a change. This is also why the Cell I teach is a free floating plate system . So the plates can be removed and respond freely .
Its very complicated to explain. I am learning more and more how to do that every day.

Yeah, I think I'm going to try both. That is, feeding a line through the carb, and also removing it and rigging something up like he does in the next video. I'll try them both and see which one the engine likes best.

I've also got a second carb for this engine that I can play around with. But I'm going to cookup a backflow bubbler first. Plenty of time; I don't care if I come in last, as long as I win. lol.

Yes but... won't that restrict waterflow? How does the water get in around the cells and the hydrogen escape?

Heh... I'll try it; afterall, I've got nothin' to lose!

self pumping  in through the bottom out through the top . and if you add a pump it will increase even more  output.
the cool thing about GOOP is you can pull the stuff off like a rubber band most of the time. I would also say to sand all the plates down with a 24 or 36 grit   to open the surface up   this also will aid in production. Sanding in a vertical fashion is what I have found to work the best.

Do you know mozon1967 on YouTube . He is also working on a tractor.
Really nice guy  . He just had a pretty scary explosion a few days ago

Yep, I've been watching in the background. Haven't contacted him yet... maybe I should handshake. :P

Have been trying not to bug people too much until I'm a little further along. There's only so many hours in a day for all of us. Doesn't seem right to borrow other people's time too much until I've at least proved that I'm serious.

Mark.

What a day.

I installed a bubbler, but... no bubbles?

Added a dash of electrolyte. Overheated my coil & blew my primary fuse. Visited a half dozen stores for a replacement fuse. Nobody carries that style.

Bypassed fuse. Lots of activity in the cell but still no bubbles.

Leaks. Must be leaks. 

I borrowed a suggestion (I think from IH's thread) to turn the cell upside down. Nice. I can't find the reference now, but thank you to whoever suggested it.

All the gas had been pushing out through the holes for my charge terminals, which is a little scary since the only accidental pop I've had so far was caused by the spark from taking a gator clamp off the terminal without cutting the power first.

I'm starting to appreciate the importance of safety and... perseverance.
And to think...this is only the beginning.

IronHead:  if you're reading this... it's okay to stop laughing now. :-)

Cheers, Mark.

Last week, I hooked my (10x) 3"x11" plates up to a 400watt 110v inverter... but fried the inverter.

This weekend I drained the water, added new distilled water with no electrolyte, and put 12v to the cell for 5 mins to warm it up. There was virtually no draw, sparse activity in the cell.

I replaced the 400watt deal with a 1kw, 115v AC inverter fused @ 20amps. Plugged-in the cell, and popped my fuse.

I decided to try hooking my unit up to the power mains, which produced absolutely no activity and blew a  20 amp fuse after 5 mins of runtime. I don't understand why I would get good activity in the cell @ 12v & 10a, and then nothing when I bump up to 115V! And why is there so much draw with absolutely no electrolyte?

So... I'm now planning to put this project on the back burner for a little bit, and get my hands on some new Stainless and set myself to work at reproducing IH's test cell. And I'll go from there. In spite of my 12v successes with this cell, I know it's not producing enough to run my 12HP engine.  It's time for me to join the rest of the class.

The good news is: my 12HP engine and gen head will be ready and waiting for me when I come out the other side. lol.

Cheers, Mark.

Yo, Mark;
If ya cain't reduce the conductivity of yer water, try deionized water  if y'all can get some.   Better yet, go thru the cell and double yer spacing.    Conductivity is a function of gap times dielectric coefficient of water, or the reciprocal of that, I think.

D I water only in the cell, and slowly adding a one molar solution of KOH [ that's 56.1 grams divided by percentage purity = add this weight to 1 litre D I water] will get you there, as long as y'all mix thoroughly whenever ye add.   Stick an air hose in the bottom af cell and let the bubbles mix it fer ya.   Jes a little whisper of air.

Thanks, Turtle... but I still don't understand why there was absolutely no production @ 115v. Does this make any sense to you?

Try adding a diode to change the ac to dc, not a rectifier... ;)

@chuukie;
A single diode will allow half-wave ac to reach the cell, and the pulsing may indeed be beneficial.  The bridge rectifier is four diodes in a diamond configuration, and when properly arrayed, will provide constant full wave (albeit 120 Hz) DC  out.

@ Aphasiac;
Don't tell me yer sendin' AC to that thar monster... Say it ain't so, Martha!?!

AC won't git y'all where you wanna go.   Gots to be DC with each plate maintaining the same polarity all the time.   By pulsing, we refer to sending a pulse of DC current, then shutting it off fer a time, thenceforth applying said pulse once again, ad infinitum ad nauseum.   Not unlike the light bub in yer flashmight whenever ye turn the switch on and off in rapid succession.

AC reverses the polarity 60 times a second (or whatever yer system runs at) and there ain't no time for the electrolytic process to get underway before the current turns around and heads the other direction.

Yes, there are systems that use AC riding on a DC main... we ain't goin' there in this thread  (and I know next to nuthin' about that at this stage anyhow).

Mark, ol' buddy... y'all ain't lost it, have ye?  Say it ain't so!!!
