Plankton Sampler
(Click on the thumbnail for larger view)

This is Charlie Miller's Plankton Sampler.
The basic idea is that sea water is pumped into one of the possible nets,
and then the passing disks can be used to select another net.

Here is Charlie Miller again, working on the ring.

This shows the factory floor where pieces are being assembled.
There is a pump in the background, and a water cone in the center.
The sliding disks are in the foreground.

This shows the pinion which drives the disks past each other.

This shows the pump which moves the water around.

This is another look at the pinion.

This is the carousel drive motor package. It contains a DC gearmotor
which is coupled via a shaft seal to the external sprocket. A roller
chain drives the shaft that extends upward, not installed when this
picture was taken, via the universal joint. A pinion at the upper end
of the driveshaft meshes with an internal-tooth ring gear to turn the net carousel.

Here are Mike and Charlie assembling some pieces on the bottom of the disks.
