Esquire

As we mentioned in our earlier post on the Esquire E-Ink cover, we have uncovered some additional details regarding the operation of this interesting E-Ink evaluation board set. There are two eight-stage shift-and-store bus registers (HEF4094BT) that drive each of the two E-Ink panels. The PIC12F629 controls the state of the HEF4094BT outputs: positive voltage, negative voltage, high impedance off, and shift register stage.

Not since the November 3, 1948 Chicago Tribune erroneously blared “Dewey Defeats Truman” has a publication’s cover caused such a visceral stir among its readership. Attempting to make a solid technological statement, the October 2008 cover of Esquire magazine featured two embedded 2 ¼- x 5-inch E-Ink panels.
