Will you actually build prototype circuits for folks, or just the PCB and provide assistance?
I review alternative Energy sites, and have been interested in building some of the devices, but my knowledge of electronics has prohibited me from doing it. That coupled with the fact that I am concerned about building a quality device. If I build half *ssed electronics, and it doesn't work, all I've proved is that half *ssed stuff don't work.
For example if I wanted your waveform generator that you suggest is good for playing with electrolysis as a completed unit, that I supply the battery/power input and the actual cell to, what would you charge?
If I wanted to vary the output voltage to the anode/cathode, what type of circuit/equiment would be needed? What voltages can be acheived within reason?

Paul, See the Email I sent you.
But just for others readng this: I Prefer NOT to Build any of these projects. The Purpose of my site is to give the Hobbiest Plans and Schematics of devices THEY CAN MAKE THEMSELVES.

get a couple of easy electronic projects, some places do soldering course kits that include a couple of simple project pcb's, these are really easy, once you get confidence with that constructing stuff from plans will not be so hard. if you have a local electronics component shop, they bloke behind the counter can be very usefull advising what to do, alternative components etc, i know, i used to be one of those blokes. sean.

I "prefer" to only supply PCB's and assistance. Sometimes I will build Completed Units, But NOT in the Summer time. I have Better things to do. Possibly in the Winter when it too cold here do do other stuff outside.
It would depend on "What Exactially you want", and also "where you live".
PWM Doesn't Vary Output Voltage. It Varies Duty Cycle.

Hi, My name is Johan. Can you assist me with signal pulse generators that can be used with a hydrogen generator on-board a vehicle? I tried to reach CL SYSTEM with no success.
Contact me on p.g.eng@mweb.co.za
Thank you
Johan

I Prefer NOT to build any completed devices. THATS BORING, doing it over and over again. Besides if you don't understand How to Build it and How it works, you will never succeed. Quality Device? What is That? Also, PWM DOES "NOT" VARY THE OUTPUT VOLTAGE or Even the OUTPUT CURRENT. It Varies the DUTY CYCLE, Which in Essence varies the "AVERAGE CURRENT CONSUMPTION". You Need to Understand This. As it says in my Write-up: I Don't believe that my PWM Circuit does ANY Better than just Plain DC. Except it Allows for a good AVERAGE Current Control. On the Other hand, If you have a Circuit of a Device that Really Does work and is "Efficient" in Producing Hydrogen, I would like to see it. And If I believed it had Possibilities of REALLY WORKING, I would Build it and Test It. And If it worked, I would Give it to you for FREE. As to Practical Limits on that Simple Hydrogen Generator Circuit. At 12 Volts, Probably 100 hundred amps or so. At a Voltage of 100 volts, Probably up to 10 amps. At a Voltage of 500 Volts, Possibly 1 amp. Higher, Depends on What Voltage MosFets are Available. Take care.......Gary

Hi, I just made a hydrolyser but I have no idea how much gas it produces. How can I measure the gas output? Also, how many plates or conducting surfaces is considered ideal? Just as a word of warning, don't try to light the hydrogen to get a flame. It burns back too quickly and blows up your bubbler!!!

The Easiest way to measure the amount of gas is to use a bottle that is full of water and Inverted in a Container of water. Than you place your output tube so it bubbles into the bottle. Time How long it take to fill the bottle with gas and How Long it takes. Knowing the Volume and Time, you can calculate Gas Flow. If you want to Ignite this gas, ALWAYS use a well designed "Bubbler" to Prevent an explosion of the cell. Hi, I just made a hydrolyser but I have no idea how much gas it produces.

Thanks Gary, that is very helpful. The reason I made the bubbler out of tranparent plastic was to see the gas produced. This being my first attempt. Won't put flame to it next time! Is there an ideal number of reactive plates when using a 12 volt power source?

Not sure of your definition of "Reactive Plates"?
In My Opinion, The Best cell is a Series Cell, consisting of one postive and one Negative with 5 or 6 Neutral plates between these.
And this cell must be made so No Water passes around (also not under or over) any of the plates.

Hi Gary, I am not sure I understand why you wouldn't connect each plate to power +-+-+- to get current flowing between the plates so the electrolosys is more effective? In this way each plate has two reactive sides except the two outside plates. Also, why can't these plates sit in a common solution like in a cannister or bath? Sorry about all the questions but I would like to understand more about it. Thanks

Sorry about all the questions but I would like to understand more about it. Thanks A +-+-+- Creates a Parallel Cell. (It Draws High Current at a Low Voltage.) Typically a Parallel cell has an operating voltage of about 2 Volts. But your supply is 12 volts, so you now have a Greater drop through the PWM circuit to Control the current. In a Series cell, you have + N N N N N - for about 12 volts. Or + N N N N N N - for about 14 Volts. In the Above, Cells, Voltage Equils Close to Battery Voltage. This gives Greater Efficiency. If Water flow Around the Plates, that current flow Around the plates Creates mostly HEAT in the water, but not much hydrogen. This would be like having a series of flashlight batterys wired in series and having a Resistor connected from + to -, Wasting Power. (The water flowing around is Like this Resistor.) But Build whatever you want!

Thanks Gary that explains a lot. How do you monitor the water level in the seperate cells and what ratio of sodium hydoxide to water do you need for best results? Using the series cell example, what sort of amps would you draw from a 12-14 volt system? I have built a parallel cell with 3 tubes which pulls quite a few amps. Will more tubes mean more amps? Thanks, Stew.

Using the series cell example, what sort of amps would you draw from a 12-14 volt system? I have built a parallel cell with 3 tubes which pulls quite a few amps. Will more tubes mean more amps? Thanks, Stew. I don't know why people try to come up with Fancy Names like: "Pulsed hydrolizer"? It is plain and Simple, "Electrolysis of Water". Possibly with the use of "PWM" to help control current. YES, More Plates or Tubes Equils More Surface area, and EQUILS MORE CURRENT. And Tubes are NOT as Efficient as Flat Plates. They only give the "APPEARANCE" to produce more hydrogen, because of the relatively Small opening at the top of the tube. How Much, It Depends on the Quality of the Sodium hydroxide used. So its really not practical to give an exact amount. Some Commerical grades of Sodium Hydroxide are not very good. Reagent or Analytical grades are much better and usually come with an analysis of the content. I suggest building a particular cell and monitor Current, while you increase the concentration. (And Make Sure your Voltage also Stays CONSTANT.) ** Use a Specified amount of water, say 1 liter and Add the sodium hydroxide in Specific Amounts, possibly 5 grams at a time. Than you can determine a precise ratio for your particular chemical. But requardless of getting Maximum Current flow with the Sodium Hydroxide, (which increases efficiency and Reduces Heat production) you now should use a good PWM circuit to Control Current. Currents Greater than about 20 to 25 Amps in a car is NOT very practical. Especially if you want to protect your alternator.
