Hello,

What kind of chips do you have?
Are there digital chips from the 7400 or 4000 series?
Is there a NE555?

Greetings,
Bertus

What Bertus said, what are your parts? There are lots of ways to do this, we'll keep it simple as we can. You're about the same age as I was when I started, maybe younger. I always liked the simple visual stuff best, though sirens are always good.
