I was interested in making a digital clock out of 74* series chips. The only thing I am stuck on is generating a precise clock cycle. I'm assuming a 555 is no where near accurate enough.
I was thinking about using a crystal, but I have no clue how to make one work, or how to divide one down to 1 Hz.
Could someone point me in the right direction? I don't mind ordering another type of crystal but the ones I do have on hand are 8 MHz and 4 MHz.
Update: If anyone stumbles upon this thread I did eventually build this clock using a quartz clock circuit as the time base. Thanks for the advice jgessling!
