50 years old this year; a timer / oscillator that I first used in school in the 70's & 80's, and currently using as part of a circuit to make semaphore trafficators more obvious to modern traffic



Makes me feel old!

I'm ashamed to say that I wouldn't have known what it was when I was at school.

The only timer I remember was the metronome that I used when practicing the piano.
