Rhythm generator

[David Halliday (Volt Computer)]

Electronotes had a list of how to do symmetrical ( 50% duty cycle square
wave ) divide-by for all integers from 2 through 13 or so ( don't have the
issue in front of me ). including odd integers ( 3, 5, 7, etc... )

I seem to recall that this is also in Art of Electronics

Scott,

This would require separate parallel counters and some decoding logic driven
from a common clock.  A binary counter will only generate powers of two
divisions.
