7 Segment Counters Circuit Tested

A project log for Hackaday Clock A Day Entry: CMOS Logic Clock

This is my entry into the informal Hackaday "Clock a day" project. A 7 Segment LED CMOS clock.

 I built a small test circuit for the CD4026 decade counters and 7 segment LEDs and connected it up to Ben Eater's clock, which I built a while ago. All good, everything worked.

Next up: build the 1Hz crystal oscillator test circuit. After that, the counter logic reset circuitry needs to be tested and then I will be ready to move to PCB.
