7400 competition entry: 4000 series CMOS 24 hour clock

Posted on Friday, October 12th, 2012 in 7400 contest, contest by DP

Easton made this 4000-series CMOS 24-hour clock as a final high school electronics class project. Rather than using a microcontroller he chose to use CMOS ICs including a 4060 and 4013 to generate the 1Hz signal. This is the latest entry in the Open 7400 Logic Competition.

For the last couple months a friend and I have been working on a 4000 series based clock in electronics class. After having failed building a FM receiver, we opted for a clock. We didn’t go the microcontroller way, but old school ICs. So, we created a circuit for a simple clock.

Build something that uses or abuses a logic chip and get amazing boards, tools, and other swag. The Open 7400 Logic Competition promotes awareness of the basic building blocks of modern circuits. Devious geeks ignited the computer revolution with discrete logic computers, what can you do? Details and entry form here.
