To whom.......... There is a relatively cheap gas flow meter availible on E-bay. I hate to keep metioning them, but I find if I can't find it anywhere else, you guessed it, it's on E-bay. That's where I finally found the high current C-mos chips available for the project Gary is discussing here. By the way, in case some one else doesn't know, a different method for making PC boards is available now. No more messy photo resist etc. I just found this on Youtube.com, I've tried it, works great. Uses "Press-N-Peel PCB Transfer Film." You have to have a laser printer, or copy machine. I used the local Library's copy machine (only cost 5 cents.) Be aware this method adds a step so you have to ad another to re-reverse the image. I use Print Artist Platinum to "flip" the image before I head to the Library. I didn't try it, but I've heard bubble-jet ink won't work. Thanks, Ron.

No, the bubble-jet printers do not work. You have to have toner deposited on the transfer film to work. One other recommendation. Don't use steel wool to remove the oxidation layer on the pcb. Find a scratch free product or give a quick immersion in etchant. I've found that deep scratches allow etchant to get under the resist layer. The result is that very fine lines are often degraded or broken entirely. You want your board to be etched quickly. I am going to try the muriatic acid and peroxide formula. Will let you know. rmeyn

I'm told that the High Current Mosfet is Also Available from Digikey. But I just use an "RFP50N06" 50 amps at 60 volts. And Cheaper. I have also just Updated that Current Limited PWM article and Schematic. Presently I am working on a good 7 cell Series Cell, that can be easily made by anyone interested in doing so. Lots of other things to do, but I hope to get this posted in the near future. Along with real Data. Gary To whom.......... There is a relatively cheap gas flow meter availible on E-bay.

Well, I guess I won't be mentioning E-bay any more. Be aware, as of Sept 1, you will only be *allowed* to buy and sell with Pay-pal. M.O.'s and checks will no longer be allowed. I resigned my membership earlier today. I've heard they now have 51% control of Craig's list.

I resigned my membership earlier today. I've heard they now have 51% control of Craig's list. I can understand no cheques, becauseof bad ones. I have only ever bout 3 items from Ebay. All were CASH money, actually mailed to the person. (Actually, only Cash to buy Everything I get.) And If they won't accept CASH, I won't buy from Ebay anymore either. I hate all this money tracking on credit cards and Pay-pal.

IN THIS PROJECT imade a PSB and solder some componenets on it but still not complete, ifeel if it will work(sure) then how i will oxegon from it and how I will saprate hydrogen fron it , please send me complete diamention clearly to under stand JAR or Box where this is assambeld Thank you

But Seperating the Hydrogen and Oxygen REQUIRES a Special type of cell. Not really very Practrical if you intend to use this in a car.

Gary, As my name says I am John. I live in Port Elizabeth South Africa. English is not my mother tongue but I'll do my best. We must bear with people that are not as well versed as we are, seeing as we all hail from different backgrounds. To everyone battling with the language, hang in there, it does get easier in time. Quite an interesting site you offer Gary, and rest assured, I think we all appreciate your doings. I actually originally became a member to get the circuit on the lazer alarm. In our country, crime is rife and we have to contend with a lot. Better to be safe than sorry.

hello, I have been working with a dry cell for over a little over 1 month now, i have built the Pulse width Modulator that I have picked out from the electronic projects from Chemelect. I would have to say it works Awesome!!! The Duty, Limit and Freq, work great, and all can be noticed with a simple light bulb. Though i had a hell of time trying to get it to work the first time, but once I did, it did wonders for my Cell and my cars Battery (Amps) and production of HHO. Anyways, if anyone is wondering what is the best Mosfets to to use on their projects, i would have to say to do your homework on what is best for what you are using it for. First of all (if it is going to be used in a car using an electrolyzer) i don't think you need anything over 30 AMPS but i would have to say a 50 amp wouldn't hurt to install. If anyone is having a hard time getting a PWM going, I can give out a hand ...Gosh i can even just give you the Express PCB Layout that i made myself from CHEMELEC Projects also FROM AKA ( ZeroFossilfuel..www.alt-nrg.org). Well anyways if anyone is interested i am just an email away.
Thank gbetromero@hotmail.com
