Homebrew Computing refers to the practice of building and modifying personal computers and related hardware by enthusiasts, often using readily available components. This movement gained popularity in the 1970s and 1980s, particularly with the rise of the Homebrew Computer Club, where hobbyists shared ideas and designs. The term also encompasses the DIY culture surrounding software development, where individuals create their own programs or modify existing ones. This spirit of innovation has led to the creation of many influential technologies, including early versions of the Apple I and Atari systems, which were often developed by passionate individuals working from home.
