Bob - it would be much appreciated if you could indicate the details of a
switching circuit that keeps on working!

Kevin,
"Ole Bob" sold a number of constant voltage reversible polarity machines
about two years ago. I might even have a shemactic left around here somewhere.
The develpoment unit had a relay but it lasted for only a few runs then I went
to all solid state using a motor control IC for the output.

A while back I came to the same conclusion re cathode area and plate-out.
After having little improvement with going from large area stainless cathodes
to 1/16" diameter stainless wire cathodes, toyed with borrowing an idea from
the Microwater people - cocoon the cathode(s) in a membrane such as chamois,
that allows current flow but restricts access of silver ions to the cathode
surface. However I believe the best solution is to borrow another idea that a
CS vendor (can't recall who) uses - reverse the polarity regularly. I think
that vendor's machine switched polarity about once a minute. An adjustable
timer is preferable, as optimum switching period probably will vary depending
on the particular setup used. It neatly solves a number of issues. No need to
clean the cathode surfaces of oxide buildup. No need to filter the brew. No
need to worry about how much silver is lost via plate-out - should be
negligible. The disadvantages are increased complexity and cost, and the need
to ensure that all electrodes are silver. To me, benefits outweigh costs. Any
electronics enthusiasts on the list willing to come up with a DIY circuit
design?
