there are three different clocks that i have built in this showcase,
they all have some of the same principal rules;
the buttons above the 4 digit bit inputs are to move the face below it up by 1;
the button off to the side on the first and second are used to reset the clock if need be;
the input next to the box labeled 'P' is to turn it on or off
they all have slightly different quirks though
the first one is the very first prototype of a digital clock that i have made
the second is a smaller design that i shoved the wires from the previous into their own bok to make it look nicer; this was the first legitimate one though.
the third and final clock is what i dub the mini clock because it is my smallest clock that i have ever made; i essentially made some tweaks to the wiring and then put that on to its own very small circuit, the mini has a toggleable reset and power
There's several buttons in the circuit. If you figure out what those do, the laws of time of this circuit's universe are yours to behold.
Note to future me to fix the following bug (if it even exists in the real world due to propagation delay).
The set 1 function of #2 works in the sub-circuit but fails to work for the output pulse in the main circuit. This is troubling to say the least. So I've decided to change hour 12:00 to 00:00.
