Do It Yourself Instructions Motherlode: Appropedia Wiki
For truly sustainable change, our technology needs to not only provide a solution, but it needs to be appropriate - appropriate to the environmental, economic, and cultural situation. Appropriate technology tends to be simple technologies which are suitable for use in developing nations or in less developed rural areas. For instance, photovoltaic panels and large battery banks don't make much sense for areas without the means to purchase or maintain them.
The absolute best resource that I've found for appropriate technology is Appropedia, an appropriate technology wiki with user generated and edited content. Do it yourself-ers, people looking for ways to help others help themselves, and anyone working for positive change in the world will find something to use and to share at Appropedia.
