Today I tried soldering the 12awg wire as a output for the electrodes
I was able to solder as long as it was directly come from clean step to solder still wet
After copper is oxidized by air it become harder
It still not very solid but made a good electric connection although fragile can be better fixed with epoxy
For that I used battery fluid for preparing the electrode and for the electroplating (sulfuric acid)
Current was much better than the solution I had before
At 2,5 v copper deposited well very rapidly… i than rinsed and brushed with steel wool and repeat 3 times
Only some 30 seconds electrodeposition at a time and the polished desired side must be not facing the copper anodes
This electrodes will be glued at an acrylic and wires will be isolated
This will form a two cell stack with the 4 electrodes
They will have a ring separating the water in one stack from the other
It will have a hole so the gas can go out from it at the region where there should be zero volts… so only the upper cell will be visible in the vertical stack with the top open
The acrylic has 200mm so as the pvc pipe and the two II cores that goes inside of it
Outside the pipe goes the giant coil
The core will make the voltage linear over the cell until it saturates
