Paul Elkins started filling sketchbooks at age eight, and by adulthood he had gone through 25 more of them, doodling mini submarines, backpack helicopters, gas vapor carburetors, and turbo-powered skateboards. The film follows him from page to workshop, where those doodles become working objects: a Mochet-style velocycle pedal car, a foldable kayak built from Coroplast that weighs seven pounds, a bicycle camper, and micro-shelters small enough to carry but fitted with solar showers and running water. Elkins learned to build this way before the internet existed, teaching himself from Popular Mechanics, Mother Earth News, and whatever library books he could find, a research method the film contrasts with how easy tinkering has become today. He calls himself a conceptual artist rather than an inventor, having never patented or sold a design, though with retirement from Boeing approaching he considers releasing plans to fund further work. The film treats his garage and his blog, ElkinsDIY, as the real record of a self-taught engineer who never stopped doodling.
