Instructables is a web-based documentation platform where people share what they do and how they do it, learn from and collaborate with ­others.

Instructables is the combination of a number of things. Firstly, there are the Instructables themselves. These are step-by-step descriptions of things people want to share. They are educational, inspirational, and often replicable.

You are also given the opportunity to comment, ask questions, give praise, or offer improvements; this sets up a conversation between the project author and the community. Why not try and build the amazing Tesla CD Turbine.
