With electronics, the sophistication of modern devices makes it difficult to combine these values. Instead, when people make electronics today, they generally use toolkits and other prototyping processes that aren’t well suited to extended use. This dissertation investigates digital fabrication (of both electronic circuit boards and enclosures) as an alternative approach to DIY electronics, one that can support individuals in both making devices and using them in their daily lives. The dissertation explores three questions: (1) What are the scope and limits of the personal fabrication of electronic products? (2) How can we engage people in the personal fabrication of electronic products? (3) Why make electronic products using personal fabrication? These questions are explored through two investigations. The first is a DIY cellphone, including an autobiographical approach exploring my making and use of the device. Also documented are workshops and other dissemination in which others have made their own phones. The second investigation is a six-week workshop in which participants designed and made internet-connected devices. The investigations reveal personal fabrication as a robust, open- ended, and nuanced means of making devices for use in daily life, but with limitations and constraints imposed by the commercial ecosystem surrounding this DIY practice and by the nature of electronic products. Analysis of the workshops reveals multiple trajectories that people take in these activities; the computational concepts, skills, and practices they develop; and strategies for engaging them. Finally, the investigations reveal multiple values for the personal fabrication of electronic products, including its ability to transform people’s relationships with the technology in their lives.

They serve a purpose, allow us to do things we couldn’t do otherwise, or to do them faster, better, easier. Other things provide us with an opportunity to exercise our creativity, to enjoy an experience, to develop our abilities. Making things for use in our own lives is a chance to combine these values. When we knit a hat, build a chair, or even just cook dinner, we exercise our creativity and invest meaning in an activity — but we also have something to keep us warm, a place to sit, and food to eat. In some areas of our lives, it’s difficult to combine these values. Today’s electronic products provide us with incredible value. With these devices, we can stay in touch, access information, and entertain ourselves wherever we are. And yet, while these products increasingly pervade our lives, most of us have little idea of how they’re made and almost no involvement in their production. This wasn’t always the case. In the 1950s and 60s, it wasn’t uncommon for technically-minded individuals to assemble their own products from do-it-yourself kits. These kits were often comparable in quality to commercial products and significantly cheaper. Assembling them for oneself involved similar processes and tools as the ones used in industry, just on a smaller scale. These kits didn’t necessarily provide much flexibility or creative freedom to the person assembling them — but at least they were an opportunity to participate in the process of making an electronic product. The complexity and sophistication of today’s electronic products — and the tools and processes used to assemble them — means that it’s no longer possible for individuals, no matter how skilled, to replicate these devices on their own. Instead, over the past three decades efforts to engage amateurs in working with electronics have frequently taken the form of toolkits, collections of higher-level physical modules which can be combined in a variety of configurations. These toolkits have a number of advantages. They encapsulate the underlying complexity of the electronic circuits involved. They facilitate tinkering by making it quick and easy to try out new configurations of modules. They provide a curated set of components which work well together and suggest possible uses. These properties make them well-suited to creative exploration and meaningful experiences. Toolkits, however, are less well-suited to the construction of products
