The (long) story of the relay clock
maxwell3e10:
Yes, I guess I've come across these projects too, using a Dekatron or just individual neon tubes as gates. But that is very advanced 20th century technology:) Using relays, incandescent lamps and a pendulum one can stay entirely in the 19th century.

It is possible, I have a "pictorial diagram" for this, but it would double the amount of relays. Capacitors are a must though.
Then you can definately say it's a rats nest of wires.
Oh, and accuracy would be hard to get aswell

No relays or transistors were in the neon clock...

Ok, but I think that would require high voltage, and I don't want to go there honestly....

Use a mechanical pendulum for timing, relays for counting, and small incandescent lightbulbs. I wonder if such a thing was ever made during the early electric era.

This is what I meant would be possible

Here is one approach using just relays and resistors to build a counter.
