At this point I'm talking hypothetically, else I would be posting this in the projects forum. I've been thinking how to slowly rock the etchant solution in the bowl/pan back and forth, say around 5 seconds per cycle. It needs to be gentle, since I really don't want to make a mess.
The base arrangement might be something like this, using a piece of wire as a fulcrum.
Two separate methods suggest themselves, each with their own problems and solutions. One is a couple of magnets and electromagnets, to cause it to rock. Breadboarding a power oscillator is a snap, but the hardware is awkward.
The other is a drill motor set for slow speed and an offset cam, made out of wire or wood. I can even put a wheel on it. Mounting the motor is a minor hassle, but it is heavy enough to stay put I'm thinking.
I thought of sparge, but that can be very messy, and I don't want to mess to much with these chemicals.
Anyone else do something similar?
