Hi again all, I'm here to probably bore most of the list to death with this technical crap :-).
I had thought about this and Mike (our illustrious list owner) provided the final push to get me to try this. The BASIC Stamp (and Pics) are capable of sinking 25ma and sourcing 20ma, which is more than enough current for CS. I was concerned that this is at roughly 5 volts (+/- 10%). So I wired up a stamp, stuck a couple 2K2 resistors from the port pins in series to the probes and cobbled up a short program to do the job. I started this at 2015 my time and it is now an hour later. The initial current flow was 40 uA (micro amps or .040 ma). Now I have 48.8 uA. All other conditions are as I have done in the past - same glass, DW, probe spacing, etc. If this is going to work, it will take a LONG while, I think. Did a couple of things "just to see what would happen". attached the probes directly to the port pins - no change in current flow (expected). Immediately moved the jumpers back to the other side of the resistors :-). Tried moving the probes closer together and at around 1/8" (the wires are far from straight :) I got the current flow up to 0.1 ma. Moved those back to the original 2.75" spacing. Not quite sure what to think. First thought is that a higher voltage will get the job done a lot faster :-). Time is not quite of the essense, but there comes a time that is too long. I'm trying to decide whether to let this run overnight or not. May just let it run until I go to bed. Anyones thoughts on this solicited.
