A single cellphone vibration motor won't be enough to shake up a "normal" amount of fine classified material. As there are many types of such motors around with diverse offset weights, experimentation is required to find the ideal number of motors and placement which will shift the heavies down, and the lighter stuff towards the edge of the pan. If your test run can shift a decent amount of iron sand, it'll probably work well for gold. Avoid vibrations from the motors cancelling or partially nulling out each other.

Waterproofing's the easy part. I can suggest gluing a waterproof bag to the bottom of the pan. Dicapac, Aquapac and Hypergear makes small bags suitable for the purpose. A base for the rig with 2 "C" rails can be made from acrylic or spare bits of metal; this base is glued to the inside of the waterproof bag, ensuring good (indirect) contact with the bottom of the pan.

The motors are mounted in the desired placement pattern on a piece of acrylic (lets call this the sub-base) and slid into the base. Ensure tight contact between base and sub-base. If your batteries and controls are externally connected to the rig by wires, use a cable gland (IP68 waterproof rating) to allow ingress into the waterproof bag. You'll have to make some kind of fixture to attach the portion of the cable gland to the base, otherwise an undue strain will be put on the waterproof bag's material. Add a few dabs of silicone around the cable gland's base for added safety, toss in a sachet of silica gel to absorb any moisture in the waterproof bag, and you're done!


LOL!   Toys you can order that come in a brown Wrapper have them motors.

Somehow I just knew this thread was going to end up in the gutter. Smiley

Still going to try this out when the time provides. If anyone else toys around with this before me, please post your results so we don't duplicate our efforts.

Ye old curmudgeon me say there are some things that you can't change like summer,winter,fall and spring and then there are things you shouldn't mess with.  The old proven way of panning for gold is one of those things.  You can change the shape of the pan and even slip in a few riffles, but using batteries, solar panels or what ever is a no-no.  A vibrating gizmod-o isn't going to settle the gold to the bottom any better than thumping the pan against your hand a few times.

The tried and true gold pan is simplicity it's self, don't try to reinvent the wheel or the pan, they work just fine the way they are.  Wise
