Hello All, I'm *way* behind in all this, sigh...
Things have been hectic with job hunting and life in general as of late. I haven't posted any new EDRs on the web site because of the above. I do have a couple of notes on these. Continuing to run these with Ole Bobs parameters shows a definite consistancy. From whatever beginning Ico (current) I find I am reaching 4 mA in less than an hour in almost all cases. With all the distractions, I have been doing a poor job of recording the results every 15 minutes :-( but around 50-55 minutes current limiting has cut in. Thanks to Steve, I have a TDS meter to play with. Whether or not this is useful, it gives me something to look at before and after batches. Starting with whichever water I use (just starting to use a store brand (Safeway) but still have some of the Cullysprings stuff left). Both types start out with a TDS PPM of 1 (one). At the end of the run to 4 mA (run stops at one hour or when I notice current limiting in effect) I am reading a TDS PPM of 7 at the end for both batches. As a SWAG from Ole Bobs data, I was guessing at 13-15 PPM (SWAG = Scientific Wild Arsed Guess :). I rather doubt that a 2x multiplier off the TDS reading is meaningful other than that it might be telling me that the conductivity of the solution is consistant with the process. Comments? The generator is essentially "done". I still want to add an ADC (analog to digital converter) to be able to read the current value into the Stamp, but that will happen when it happens. I hope to get the schematic integrated into the web site soon. I've added the ability to control the time of run, switching frequency and current limiting to it via potentiometers (the stamp reads and controls the time of run and switching frequency, the current limiting is not (currently and may not be) dealt with by the stamp). At this point the PC is still required in the loop to be able to see the time of run and switching frequency values :( to set these, although I may well be able to calibrate them with panel labels. When I convert this from the Stamp to a Pic, I will have the hardware resources to drive an LCD display as well (the code to drive it is simple enough that code and variable space is not an issue). Well, "essentially" done :-). I'm also trying to decide if the forms and graphs of the EDRs on the web site are working as intended. They are *ell to get formatted locally and I have no idea what other people are seeing. I am considering going to a less sophisticated format. Just the table of process values, table of time, voltage, current and computed resistance in a raw preformatted *plain* text format and perhaps the charts. I would specifically appreciate hearing what people are seeing from this area of the site and comments. I'd much rather this be easily accessable, no larger than it need be (other folks in different places pay heavily by how much they download) and most of all remain with the minimum of "glitz". Comments solicited and most welcome. That's about all the news that is fit to print :-).
