"Sunburst and Luminary" author Don Eyles was a Ham, a Hacker, and a user of Plywood who Understood Juju

-- As a kid, Eyles took a summertime shop class with W4LRO.  Eyles himself went on to get his ham license -- he was K4ZHF and was active for a while on the 40 meter and 6 meter bands. 

-- He writes of how the Apollo software acquired more "juju as labor and logic were poured into them." Juju. 

-- He describes the electronics lab in the MIT Instrumentation Laboratory: "If you had a private project you could sometimes get some simple milling done for a smile, and you could scrounge the odd resistor or capacitor... On the second floor there was a small "hackers shop" with a drill press, metal shear, a bending brake, and a few hand tools which was open to anyone, including software engineers. That was the first use of the term "hack" in a technical context, that I can recall hearing. I took the term as referring to the sometimes messy process by which perforations of suitable sizes were made in the aluminum boxes, or chassis, that were used for constructing electronic devices."  Indeed.  We hack.   

-- After describing the first integrated circuits, Eyles looks back at high school and notes that he and a friend, "after learning about truth tables, James Chambers and I had experimented with similar devices composed of relays mounted on a piece of plywood."  Plywood.
