So having a diploma in electronics and you cant even design a simple counter circuit?
You can do this with 74 series ics, ( I'd say doing it with a processr/pic is out of the question as it is too advanced for you but would be easier......)
I'll give you a clue, There are 60 mins in an hour, 60 secs to a minute, if you took a 50hz oscillator and dicide that by 50, that would give you one pulse per second...
Set a counter to advance by one count per second until it reaches 59 at which point it pulses another counter that counts upt to 59, so now we have a counting sequence that will count up to an hour...Does this help?
I'll leave the display function up to you to resolve or if some other helpful type wants to pitch in.....
I'm going to go and hide now, so I dont receive a beating for the assistance I've given you
