I shot a little video of my latest experiment with borax. It is controlled with an Android phone, IOIO microcontroller, and relay bank. I am switching back and forth between AC and DC current supplies. Pardon the mess of wires as I am early in the process. It is interesting how the electrolyte turns a copper brown color. That was after running 1 1/2 days on DC current at 5 to 13 watts. I'm using the same 8 nickels on the thoriated tungsten rod as a cathode and 4 stainless steel washers as the anode. There is more heating and almost no bubbles on AC. I'm not sure what brown color is about. I've seen this repeatedly.
What I'm interested to try is to see the max temperature achieved by AC alone, then DC alone, and then AC and DC alternating for different periods of time. http://youtu.be/sH90M85S2mE Regards, Jack
