Dudes,
I know this topic has been posted a million times, and also I have already know how to set up one, the only thing left are the chips which I'm going to order soon.
Basically, I want to run this clock on a +9V battery source, which is much easier for me.
However, the 74 series TTL is very picky as they only needed +5V and also voltage regulation.
So, if I have to use a battery, I have to change them all to CMOS, or just put a +5V voltage regulator for the 9V battery and then feed +5V to the 74 chips from it?
