Hi Everyone, Well <blush>, there has been an interesting turn of events here as best I can tell.
The experiment that I declared failed earlier this morning has taken a twist. Since I had such a "pathetic" (and unchanging) current flow and NO Tyndal effect (nothing visible to my eyes or anyone else here), I declared it "failed" and moved on. I modified the code for the controller to change the polarity switching delay from 20 minutes to one minute and uploaded that. I hooked the H-Bridge circuit back together and since there "hadn't been any effect" I hooked it up to the same container (and DW) I had used for the "failed" experiment. fully expecting to see the same basic initial current flow I normally have had when starting up using the 27V supply. Surprise! It first looked like the current was 2.77 ma (not an autoranging meter). Humm, think I, this is in the range of "Done" for a batch. I power down and pull the probes and wipe them off - a smallish amount of medium grey deposit wipes off. Hummm.... I pick up the glass and take a swig, sure tastes like CS to me. Ok, I turn off the lights (not normally necessary) and hit it with the laser - NO Tyndal effect (this had been running at around 45 ua for 12 hours before I changed over). Now I am really confused. I hook the probes back in and cable them up. Turn on the power and look CLOSELY at the ammeter. Ah, it reads 0.366 ma - a LONG way from "done". No Tyndal and a definite taste of CS. It dawns on me that further research is *dead* for me until I get some measurement tools. Something here "isn't right"... or something is "very right". There does seem to be something here to look at, but it is going to take real measurement instrumentation to determine what is happening. I expected that if there was silver in the solution that it would show up as a Tyndal effect (if even dimly). The taste says "CS", but the Tyndal effect is simply not present. What I *think* is that I must have an incredibly small particle size ?!?!?!?!? Suddenly I am more confused about this than I was to begin with. Just keeping everyone informed :-).
