The storage unit is a corn cob with various kernels punched out/left in to represent ones and zeros. The cob is held via those little corn forks, except it can rotate freely around its long axis so that a given row can be aligned beneath a bar on which rides a belt-driven read-head. The read-head is a light sensor that feeds into a small microcontroller that uses a dynamic algorithm both to position the head axially and linearly over the kernels, and to judge kernel presence/absence. The controller must contain logic to identify kernel spacing, similar to timing recovery in an analog modulated bit stream.
Not sure what I'd use it for... Maybe for controlling my robot corn army! Oh wait, I didn't just say that. Have a corn dog and some corn brandy!
