"Contestants Jen and Earl compete to see who is most entertaining while eating corn off the cob. This is a style competition, not a race!"You may want to keep the kids in the other room when you watch this video (its a BIT racy). Say Jen, come to my place, and I'll give you a challenge!
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.
