60 LEDs and a mcrocontroller is one way. Another might be a half dozen Johnson decade counters like the CD4017
A guy did something like this with all transistors instead of an IC. I think it took about 200 transistors in order to accomplish a effective clock, nowadays you can simply get it in an IC. I don't know of any IC's out there that would do the trick, but If you google it I'm sure you could find it.
The coinage "googled" is becoming more popular!
How accurate does it need to be?
I'm sure he'd like it to be as accurate as possible. Does that answer your question?Originally Posted by birdman0_o
If that's the case then running the 4017's with a 555 is out of the questionI'm sure he'd like it to be as accurate as possible. Does that answer your question?
True, but then it would depend on his budget and also his preference. Would he like to afford a better clock with more accurate circuitry involved, or does he want to make do with parts he may already have?If that's the case then running the 4017's with a 555 is out of the question
Based on the specification in the original post 60 LEDs and a 60 position rotary switch and just turn the knob once per minute would work.
