“The purpose of this instructable is not to tell you how you can do whatever you’d like your home to do. Instead it has been written to make an idea a reality but also turn madness into sanity by understanding the limits (technology, cost, time required, safety…). There a lot of very good guides and articles on the web to understand many things in very extensive details. This is not what we want. We want the big picture. What are the basic skills we can learn or improve. What we should touch.”
