Title: [Entry] CMOS Digital Clock
Post by: Giuss on October 18, 2011, 03:33:48 pm
Hi, here there is my digital clock based only on standard 40xx chips.

The clock have four 7 segment display, crystal timebase and back-up battery. I built it few years ago and it works perfectly.

I've published the project with schematic and real pictures on my personal website, let me know if I must publish it directly in the forum.

This is the link : http://http://www.webalice.it/giussdp/cmos_clock/

Sorry if my english is not perfect :)

Regards
Giuseppe
