@bikerglen High frequency noise, even low amplitude, can be a bear for the derivative since it “amplifies” high frequencies. Depending on what your noise looks like and whether you care about the time delay of the extra analog_read calls, a low pass filter might help.

Check out the guts of a #Soyuz mechanical navigation computer thought to be from the The Apollo-Soyuz Test Project. Apparently this style of nav computer was still used until ~2001.

@kenshirriff how has reverse-engineering this mechanical device compared to your normal electronics reversing process?

Fascinating thread.

As a committer on a couple of medium-popularity projects I couldn't agree more with this:
