Selfrunning HHO system with 400 Watts additional output

[bolt]

You don't have to make advanced PWM's to test this engine.  DC is good enough already COP 3 via ICE so if you tune everything correctly it will work from the get go. Even if you are very sloppy and use all of the COP 3 to keep the engine running with nothing left for a load it makes a nice OU water powered heater:)

While Les has covered all the dots and crossed the t's IMO is terribly complex for DIY replication. It looks like a 1980's TV circuit LOL

You can do everything required using an AVR micro which only cost about 15 bucks. Then you add a hall sensor to pin 2, one power fet to pin 5 via a driver and a car ignition coil and you are good to go.

Agreed!

Yup!

Yea
Les's PWM circuit is awesome, especially the clock synchronization/amplification stages.  Yeah it's old school, but I'm gonna mod it for TPU type work, in combination with a microcontroller to replace the frequency generator chip.

Anyway, I use Arduinos normally; I looked it up and your 'AVR microcontroller' is Atmel, which is nice.

So where do you mount the hall sensor and its associated magnet to modify the generator to run on HHO?  How does the car ignition coil fit into the circuit?   Do you have schematics / source code for the HHO engine modification using the Atmel microcontroller?

Thanks,

Put the hall almost anywhere to collect the pulses off the magnet that's already on the flywheel. It should be somewhere advanced so everything in software has delay control. Just remake simple fet trigger to car coil for new spark system and make everything factory fitted redundant. Basically as the German guys did on their machine.

My brother is doing the code he might open source it i don't know its up to him. He could even charge a small fee for it when its ready.  I can hack code and tweak stuff and do a few lines here and there but im not a code writer.  I just put the flow chart together for start init, set first pulse delay, find engine spark phase blank, set run flag, set angular degrees, set run speed, adjust pwm for gas control and i got emergency over speed control to adjust to the timing etc.  There is even a bit of Fuzzy Logic so the timing sets for best running and lowest HHO usage.

Its a fair bit of coding but the idea is we have no mechanical modifications whatsoever from standard engine. There are no plastic timing cogs, no magnets bolted on inlet  valves the only thing to do is take off tank and carb and make a little bolt on air manifold/ HHO injector. So everything can go back to make this a virgin genset. Its planned to start off the mains directly via control stuff or using jump start batteries 24 volts to gas up the cell. It should only need 300 watts to get a start loop going.   Once the engine is running  pull the jump cables off. Hand pull or electric drill start will do either.

Its not running yet its taken since Christmas for parts procurement, money and time to do this but we are very close now.

Seeing that this [HHO] is where you are spending your time and hard earned money [and I know from your posts you ain't rich]
That speaks "Volumes" to me!
What are you using for a cell?User Woodpecker hasn't been around here for a long time ,his cells I understand are quite
effective!


Thanks

Bolt... that would be cool if you brother open sourced the microcontroller code.  I generally open source my microcontroller projects -- but I'm lucky enough to have a day job.

The idea sounds great.  I am sure it will work. Have you decided on a particular genset , or do you think any brand and type will work?

Thanks,
