Looking inside the Mercury Earth Path Indicator with Adam Savage

A rare navigational instrument from the cockpit of the early Mercury spacecraft. I know I had to invite him over when I learned that Adam Savage built a replica and exclaimed: “This is maybe my favorite instrument of any cockpit ever” and “I would kill to have one of these.” Photos and analysis: flic.kr/p/2owNqf1

This would be a Great STEM project for middle/high school.
A bit of mechanical engineering, and a little electrical?
