These are the Kicad design files for a CD4060 based small clock divider.
A crystal (up to about 1.5 MHz) can be used, or an external clock source can be connected. A solder jumper enables the latter.
One of the divisor outputs can be routed with a solder jumper to drive the output transistor which is open collector.
