For example here is Nikola Tesla's impoved spark-gap:

And here is a map of Earth's magnetic field:

It's true, they didn't had the advanced materials, electronic tools and components we have today but maybe when we transitioned to theese we lost some things and ideas which Tesla and other researchers demonstrated in these experiments.

I find the craftmaship and ingenuity of these experiments and tools fascinating.

I attached one document containing just a part of these tools: "Catalogue No. 10 of Physical Instruments".
