Hi, I found these videos fascinating and thought some of you would too!
From the description:
-
This introduction to the series Albert Michelson’s Harmonic Analyzer celebrates a nineteenth century mechanical computer that performed Fourier analysis by using gears, springs and levers to calculate with sines and cosines—an astonishing feat in an age before electronic computers.

I tried to also post just links for iOS users but I couldn't get it to work, sorry, links were automatically converted to embedded players??

Also there is some more bonus video on the youtube channel if you so wish and I recommend the engineer guy's other content. Great explanations and demonstrations of science and engineering.

Wow - that's amazing! Thanks for sharing this.

A little bit of CRAZY maths, but the operation for adding cosines to produce a waveform is also the same operation used for analysing a waveform to produce the cosines!
So basically by creating a machine that sums sines and cosines, you have also created a spectral analyser!!!
