Can you elaborate? Formula or charts? I'm new to this, so pardon if the question is ignorant, but doesn't the the surface area of the electrode in solution figure in? I would guess that the emitted silver for any surface area could be normalized though (surface area * current or something like this?). > I am ordering a few parts tomorrow to build the prototype, and > everything you need to build it will be detailed by the end of next > week.

I am assuming that the relay is for alternating the polarity to the electrodes here (other than evening out the wear on the electrodes, is there a point to this?). An "H Bridge" might be more efficient and less succeptable to fail over time than a mechanical relay?! > This will put a stop to all of the questions as to why "my CS turns > color," and what is my ppm. You really have to "screw-up"to get yellow. Again, I'm pretty new to this, is there a FAQ somewhere that might explain why ending up with the yellow color is not a good thing? While I am still a long way from finalizing the design :-). I'm thinking about a microcontroler that would deal with temperature of solution (this seems like an important value in the equation) and control of time, voltage (maybe) and current. Even with all I have read on this to date, I don't see how one gets any degree of consistancy with the methods and equipment that I've seen recommended / being used. Granted, again, I am new to this. I do have some experience with industrial process control and maybe I am trying to make this more difficult than it need be, but I have a hearty respect for "making medicine" that I am going to put into either myself or someone I care about :-). I've seen the abandon with which the "conventional medicine establishment" seems to dispense meds and the results :-(. Paranoid? I'm not sure yet :-), further research is required :-).
