Dual CMOS Clock Dividers
Dividers contains two independent clock dividers, each based on a different CMOS chip. One divides by powers of two, from /2 up to /128. The other has just one output, with a division between /2 and /9 selected by a rotary switch. Dividers accepts any gate or clock and can even work with audio rate signals.
Available as a built module or a beginner-friendly DIY project. All components are through hole and easy to source.
