Chiton eyes maybe be the only light field or plenoptic camera to occur in nature.




Chiton a hard shelled mollusk has hard ceramic eyes on it's back.  These eye's can not focus and produce low resolution images.

In seeing these images, having these low resolution eyes in fixed locations may actually give this creature excellent 3D depth perception and it may have excellent vision possibly far better then most fish.

This is done by combining each smaller image to act as part of a larger image sensor, where focus is achieved computationally.

Hacker Dojo Lightning Talks, 2015-04-17





I am at 11:33 in.

Wooden gears and linear positioning.  Conjugate profiles.


Here is a Linear position system that's low cost, precision, low wear. 


I wanted to use Low cost off the self parts.  This means no precision machined Steel. 

I stumbled on the Roller Pinion System (see below)  I wondered if I could do this in reverse.

To use a Roller Chain or set of Rollers (which could be ball bearing rings and a spacer in to an Aluminum L extrusion)

Roller Pinion System - The Reverse of what I want to do.
Two or more rollers engage the rack teeth in opposition at all times eliminating backlash. There is no tooth slap as with traditional rack and pinion, instead the RPS rollers approach the tooth face in a tangent path and then roll smoothly down the tooth face. This provides a smooth, quiet, low friction, fatigue free, high-efficiency rotary to linear motion conversion.

Sylvester Marsh was issued a U.S. patent for the general idea of a rack railway in September 1861,
