I am doing this with a 4060 counter but my delay time is a big number, up to all day. It is a lot more parts tho.
A .001uf cap and a 100k resistor settles things down prety well on POR.
I'm working on a solar pool/spa controller. Folks are saying PIC but I still like CMOS, particularly when it is a fairly simple truth table. Still looking for a clock but I am seriously leaning toward a garden variety alarm clock with 2 events. The more I work on this problem the simpler the logic is actually becoming.
