Back in October 2019, I finally got around to designing a PCB for the 8-bit counter. It uses the same components as the proto-boarded version, but in a small/more organized package. The design ended up being pretty simple. I used DIP packages, 5mm LEDs, and 1/2W resistors so that everything can be soldered easily by hand. No SMD components were used.
Below are some photos of the PCB design.
