PIC Tock Video Clock - PIC-Tock is a video clock using a PIC16C61. In the tradition of Marv Newland's "Bambi Meets
Godzilla", there is far too much ROM space spent on credits, which are smooth-scrolled horizontally on the
bottom of the screen. . . . [Circuit designed by Eric Smith]
PIC16F873 Digital Clock - On this page, I will introduce the PIC controled circuit which is the heart of Ultra High
Accuracy Digital Clock. For the details of the clock, refer to "Ultra High Accuracy Digital Clock version 2".
As for PIC, PIC16F873 is used in the relation of the input-output port. Also, to make a circuit compact, CPLD
is used for the peripheral. . . . [Seiichi Inoue's Web Site]

PLD implements fast four-phase clock generator - 10/27/94 EDN Design Idea The circuit in Fig 1a can clock pipelined logic in PLDs by an
external agent at one-half the usual frequency. You can use this circuit when designing pipelined ALUs and
switched-capacitor circuits. I used this circuit to drive a 40M-sample/sec CMOS flash. . . [by Said Jackson,

Poor Man's Timer - Often during testing of certain equipment and components, you would like to keep track of
the elapsed time in hours, minutes and seconds. There are some nice commercial digital timers and counters
available for just this sort of application. However, . . . [Hobby Circuit designed by Dave Johnson P.E.,
