I will add a comment to Bob's last mention on vibration, harmonics and transmutation. I was involved with a vacuum tube production problem with what we called plasmoid formation, aka EVO's. One of those things that came from the investigation was micron and sub micron surface topology. Secondary was carbon contamination. Sound familiar? Carbon contamination was minimal. The surface was nearly glass smooth on examination. We wanted to eliminate the EVO's. The fix addressed both suspect issues. Sand blasting the surface to create 1 to 5 micron topology features and in effect removing adhered carbon. EVO's went away and never returned.
We will need SEM/EDS to better characterize what is happening with the BG plates and particularly the floating plates after break in. While transmutation is important, I want to understand molecular formation at and in the vicinity of the plates. I expect to see a self organized topology that could be revealing on differences in various HHO configurations and efficiencies.

Hi John,

May be worth acquiring the spare panel, thanks for finding that.

If any of you want to have access to the live document to add details of components or edit it in other areas, please make a request.

Also, I can provide a common server space for people to exchange files easily, let me know if you are interested.

The CPU board is a relatively simple 2 layers PCB with very straight traces, so it would not be too difficult to derive the schematic: this would simplify a lot the work and will give some clues for understanding the code. To this end it would suffice a good quality high resolution picture of both sides of the board.
My guess is that the program control loop runs on polling for most of the external resources, due to non critical timings, and perhaps employs the external interrupt for the ADC only. If we can get the schematic we can figure out the peripheral addresses and so link the code to its activity and purpose. Without the schematic this task is quite hard, IMO.

Not to be critical... Just painful experience as reference.
Cheers

Quoting Mats002:
Ok, so we have a measure of electrolyzer current
going into the ADC going to the microprocessor as
8 bit(?) resolution. What can output be? A control
signal to the DC electrolyzer? DA conversion can
be constructed very simple, no need for a chip.

Ok. So speculation just slows us down until we can get a good schematic down. Current is key measure, you have to have the overall picture before understanding and interpreting the details.
