Electronics Fun & Fundamentals: Analog Reborn
A Make: magazine article by Charles Platt introducing analog computing concepts through a simple DIY project called EASY (Elementary Analog SYstem), derived from the 1961 General Electric EF-140 kit. The project uses three potentiometers and a multimeter to perform basic analog multiplication, division, and square root operations. The article also discusses the resurgence of analog computing, referencing Anabrid GmbH's educational product THAT (The Analog Thing) and the historical context of analog computers in aircraft simulation.
