:? :roll: Ummmm
I think it would be not very difficult to do with a microcontroller.
Always thinking you want to get something like this:
"0E : 1B" from usual "14: 27"
Just make a routine that waits for a second. Each time the routine is ended increment a "seconds register". Each 60 seconds you can increment your "minutes register" and clear your "seconds register". Each 60 minutes you clear both and increment the "hours register". Repeat this until you get 24 hours. Then reset all those registers, and let it start again.
With this you now have a clock. All you have to do is to connect it to some 7-seg LED blocks or to a LCD or to a LED array. Then you'll have to decide how do you want to show the hour, maybe in hex, maybe in dec, maybe in binary or in ternary or in whatever you like. They are, anyway, characters to be displayed in any sort of screen. You see? :mrgreen:
