Why not use one of these drivers (Or similar.) and use an NE555 to generate the clock pulse. https://www.ebay.co.uk/itm/TB6560-3...tor-Drivers-/350922320630?hash=item51b499aaf6
To build one from scratch you need to build two H bridges and a PWM method of controlling the current through the winding. If you just build a driver were the current is only limited by the winding resistance then the maximum stepping rate will be very low due to the inductance of the windings limiting the rate of rise of the current with a small available drive voltage.
Hi Les, I'm not wanting to build a driver, or am I not understanding your meaning?
Thanks Les, I'll check it out.Hi Jeff,
Here is a schematic for a pulse generator that uses two NE555's but you could also use a single 556.

You need to scroll down to the heading "Variable Pulse Generator Circuit Operation"
You would probably not need to switch between different capacitor values for your purpose. The output from this would go to the step input of the driver . You would just need a switch to set the direction input to zero or 5 volts to change the direction. You could also have a switch connected to the enable input of the driver module to stop and start the stepper motor. (Again setting the input to either zero or + 5 volts)

I agree with you Les, after building the circuit (with out the alternator) and testing it, I as much as proved that the circuit did not work as thought or suggested. I used the circuit for other applications, not water related, learned a bit.Hi Jeff,
The first 555 is a low frequency astable with a variable duty cycle that gates the second 555 on and off. The second 555 is also an astable with variable duty cycle. This is basically a PWM controlling the current through the rotor of the alternator which results in the power output being controlled. My opinion is that the designer does not understand electrolysis properly. Pulsing the power to the cells serves no purpose so the first 555 is not needed. The rate of production on hydrogen and oxygen is directly proportion to the current flowing through the cells.

Who would have thought a 555 timer would finally break the laws of thermodynamics and save the world with free energy!! Just think what Myers could have done with a Micro!!
I split water last year in Chemistry, we didnt do it correctly as our measurements agreed with modern physics so clearly we did something wrong! Actually I do alot of electro chemistry these days, its a good way to produce Hydrogen or oxygen for certain reactions. It can be slow but its a nice cheap and controlled way to generate small amounts of gas. I have also done alot of other electro chemistry like building a Chlorate/Perchlorate cell. Its also great for making fine copper powder, if you need it ball milling then at least your starting with a pretty fine powder to start with. I am not so keen on ball milling, I had a small batch of charcoal and sulphur go bang. Stupid to mill together in the first place!
Well, the 556 would I think give a little more control. I have looked at the 555 circuit and it should work, but really leaning toward the 556 as it will have the versatility I am looking for. Just checking to see if someone here has either built one or can steer me in the right direction to this end. Thank you for inquiring.
It depends how you make and use it, I have tried because I was interested and the following is based on that.Well LG, I don't know about breaking the laws of thermodynamics, all I do know is that Stan had something and there are many around the globe reverse engineering his invention. I am a moderator on a few other forums and have personally talked with several I know who are on the brink of cracking that egg. I have seen their equipment, their applications, their experiments, read Stan's Patents enough to know, they are very close.
I already have the drivers, what I am looking for is step and direction control for the drivers, so a circuit utilizing the 556 IC to produce a pulse to the driver circuit. This circuit could be used to test drivers and stepper motors, also for break-in of CNC equipment movements.
I guess we're all talking about different things here. You say you have motor drivers, but you want something to change speed and direction. Then you talk about pulse length(PWM). Any stepper driver I'm familiar with only uses pulse frequency not pulse width. And direction is controlled by the signal being either high(a digital '1') or low (a digital '0').
A simple 555 astable timer with a pot to vary the frequency will do for the speed. No PWM needed or wanted by the motor driver.
It depends how you make and use it, I have tried because I was interested and the following is based on that.
IF you have say an extra battery and use that to produce gas, you can feed the gas into a engine (was a 4 stroke generator for me) and you save some petrol (well obviously). But the saving is only because its cheaper to use electric to make gas than the price of petrol.
If you use the generator OR another alternator (I tried both) connected to the machine your feeding gas into, then you save nothing. Also I noticed that HHO wasnt great for the engine, if you split water and feed HHO in an engine and burn it you get............ Water, water isnt great for an engine, What I did find was a bit more power from feeding just the oxygen in, but I couldnt produce enough to keep up with revs. When I used more current and got some more Oxygen I used more petrol.
So yes you cant argue against it if you use an outside source to generate the gas, after all your adding the outside power to the engine so using less petrol. But that is way different from claiming a closed system can somehow give a net gain or something for nothing.
Often things look like they work because people dont understand the underlying mechanism, a great example was a you tube video with a demo of a special electric engine that took 12V and made 35V!! It was a super coil thing but basically a motor that floated on magnets. What the guy was excited about was the fact that he was feeding 12V in and could measure 35V on the output mosfet's.
What he didnt understand was he was measuring the inductive spike as he didnt have flyback diodes! But had he measured current instead of voltage he would have realized he wasnt gaing anything in terms of saving. But again I do think if you had a ultra efficient solar panel roof on a car then you could power a HHO cell from that and save a small amount of fuel, but your not gaining anything as such. All that happens is your turning an external power source (sunlight) into energy (electric) and using that energy to make a gas, as you feed that gas in of course you use less petrol!
But the fact remains if you use the cars alternator or even a extra one added to the engine to make the gas you use more petrol, I noticed the more gas I produced (higher current needed) the harder the engine worked(more revs needed to compensate from the alternator), as I said mine was a generator but the same works on a car. The best saving I have made by far was for our tiny tractor, I now use converted waste veg oil and mix with 20% red diesel. I save money in red diesel but it costs to make the bio fuel and it takes time, but there is a overall gain cost wise.
Simply looking at chemistry will show why it dosnt work with HHO, you use energy when you burn the gasses together and they make water. I cant remember the electron Volts and all the details but clearly there is a net loss. Shame it dosnt work as it would mean a secure energy future.
