However, while many enjoy the products of the digital electronics revo- lution, comparatively few understand the principles behind how these tools function, and fewer still have the skills required to reconfigure these systems to perform different functions. In order to ensure that these technologies support the needs of the broadest spectrum of civil society, more people need to engage with the technical mechanics of information systems – both to improve their everyday use and extend and adapt their function to meet new challenges. one of the simplest ways to engage more people in the techniques and skills required to maintain and adapt information systems is to set up computer reuse and reclamation projects. such projects offer a wide scope of opportunities for those who wish to take part: • They can learn more about how these systems can be used to create more interactive media through the development of online content and audio/video media recording/editing; • They can learn about the functioning of information systems through the installation and configuration of operating systems and software; and • They can develop electrical and mechanical skills through the main- tenance, disassembly, and construction of machine hardware. In this unit we'll examine the last of these options – developing prac- tical computer reuse and recycling projects. such projects are the foundation on which the community use of information technology is based. Creating the independent capacity to reclaim and re-purpose IT hardware allows a whole range of other projects which rely on the use of these technologies to take place. 10.1.
