Do-It-Yourself (DIY) has been a fundamental part of human life for a long time, but it is undergoing major changes driven by new tools and information. Advances in computers, software, and the internet have created an explosion of accessible DIY tools and information. This has transformed DIY from primarily practical activities motivated by need into a broader range of activities also motivated by enjoyment, self-expression, and mastery. The widespread availability of information and ability to collaborate online has further accelerated this transformation of DIY.
