We need a -punk fiction genre and aesthetic where computing never went digital.
Like going to the doctor and it hooks you up to something that looks like s modular synths, that displays patterns of colours on oscilloscopes that get interpreted by the medic.

Blip was a handheld battery powered pong game by Tomy.
what makes this game brilliant is it has no computer chips or transistor logic. it’s entirely driven by electromechanical components, with game logic being implmented in the mechanical part of “electromechanical”, and batteries only used to power lights.

it might seem a little boring and obvious but one of the most ancient and popular forms of #analogComputing is, creating lookup tables of precomputed values.
visualising data tables as charts and graphs was apparently not something anyone thought to do until the 18th century (1700s) as an reapplication of nautical maps production to non cartographic data.
the history of magic needs more attention, because it is devalued - associated with women, and minority populations. But bound up in magic is a hidden history of science, mathematics, engineering, psychology and chemistry, all before these fields got their proper names.

A vibrating reed frequency meter
it contains rows of metal reeds each tuned to resonate at a particular frequency. these worked essentially like an electromechanical fourier transform.
these were used for a variety of purposes but this one was used at power stations to tune the frequency of the alternating current. the reeds resonated with the frequency of a copper coil, electromagnetically humming with the current

the video channel “Maker’s Muse” is quite good, attempting to recreate many of the mechanisms from this 507 movements book, along with some others, using a 3D printer.

it’s a cool book, and a neat website, but for some mechanisms you just don’t get it until you see a real device moving.
there’s an anazing birdsite thread in which an artist uses these as the basis for fururistic scifi themed UI.

This is quite famous, but I’m betting that not everyone knows about this website, and that would be a shame.
