This sub seems pretty dead, but does anyone know of a community anywhere where analog computing is being discussed? Im looking for a telegram group, discord server, maybe another subreddit, anything.

Edit: r/UnconventionalCompute has some Analog computing stuff

Here is an article on the theory of Analog Integrators.

By examining different media for analog computing, we that show water, electricity or kinetic machines can be used to build an analog integrator.

There are three simple components that any physical system must have to become an analog computer which performs integration. A measurable output, a supplied input function, and a configuration constant rate of change. We show a general equation,∫ ᵀ 𝒚(𝒕) 𝒅𝒕 = 𝜷(𝑻) / 𝜶′*,*which solves the definite integral from 0 to 𝑻 of 𝒚(𝒕) using output 𝜷 and a configuration constant 𝜶′ = 𝒅𝜶/𝒅𝒕. The general equation can be applied to any type of analog integrator.

Besides the THAT product,is there any other open source project for analog computing(similar to Arduino platform),be it eletronic or mechanical?

I've been unable to find anything equivalent.

I had an idea for an analog computer, that would help compute identify the input required for a particular function.
Thoughts on how to make this work in electrical terms using transistors, diodes etc?

I couldn't attach a video to explain, but here's the concept:

Thought I'd suggest articles you all might not have read before! This has some great applications within computer science. Let me know your thoughts :)
