It spins way too fast for making CS.
High velocity particle collisions [DC and AC out gens] enhance aggromeration.

bubbles on the electrode, creating more bubbles

gets pretty slow... haven't timed it

Solutions:
Use a very small spinner
Go to pulse width motor control to keep the starting and low speed torque.
Use a gear motor.
Just barely moving the water works best.
Or best of all, just buy a mag stirrer base from you, Ode. LOL.
Aggregation is also created by a standard laboratory magnetic stirrer.

Dunno about getting one from the main man, but you can't buy one from his

How important is a mag stirrer ?
I make CS with Maple leaf coins
and 4 - 9v batteries.
I may make one using your design
if you think the brew is better with the stirrer.

With your setup you probly don't brew large volumes do you? So a stirrer may
not be necessary in your situation.

The water will not go faster than the stirrers RPM no matter how big the
spinner is.
You can slow the water velocity down using a high RPM stirrer and small
spinner, but everything [tallness, diameter] becomes interdependent and it
can get tricky...plus, there is a tendency to create a

side of the water currents on round electrodes, or eddy side where pressure

10-40 RPM works well. 100 might.

Hi Steve,
I've had good luck with ~30 to 40 rpm in a pint wide-mouth jar. The
length of the stir-bar can make a difference too; I go for ~ three
fourths of an inch, maybe up to 1-1/2. I get magnets from:

...the silverpuppy site has a nice one for a good price. cool looking too.
i shopped stirrers w/ hotplates on ebay for quite awhile while broke and
after experimenting with a hotplate decided that part isn't worth the money
since it works best to start out with the water hot but let it cool
Won't a magnetic stirrer cause the positive ions to either repel or attract
toward the stirrer and maybe even plate to it? I'm assuming the stirrer
itself is a plastic covered metal rod of some kind.

I've seen hundreds of these devices used in chemistry labs with no
cautions I am aware of as to their use. Maybe there is a chemist on
the list that can address the issue.
But just for the sake of argument lets suppose that either of these
two things happen. If the agglomeration occurs on the
Everything is chemistry... If the use of a magnetic stirrer doesn't
affect 'other' chemical reactions why should CS be any different?
In your scenario the charged particles can only move in one
direction on the flux line. If so then how is a particle more likely
to have a collision with another
