Terry,
Gee, I don't see how you can get 50 mA with 12 VDC with neat
water.
I'm only getting 1.1 mA with 9 VDC. Larger surface area?
The cell Patrick is talking about has only two or three neutral
plates - you have 16 total - 14 neutral, correct? Your
plate-to-plate voltage drop in tiny.
The neutral plates would divide the voltage drop, which you want
to be under about 1.2 per plate so that electrolysis does NOT take
place, but close to that level so that the max current can flow
w/o gas forming.
With 16 plates you can probably use 20 volts. Do you have a
wall-wart near that level? Some of the HP large block transformers
that they used to sell with their printers are 24 volts ... What
about using two wall-warts in series? you have so many free wires
you could use the plates one and sixteen (like now) and the attach
the second leads to plates 5 and 11, or some such series
arrangement.
or else try to find a block with more ripple or else what about -
one AC and one DC? sounds weird ... you could use the DC on the
end plates:one and sixteen (like now) and the attach the AC on
plates 5 and 11, or some such arrangement to get the net current
WAY up from what it is now....
