For Instructables Halloween is a really busy time of the year for them, and a perfect time to mention the community as a resource to build some great projects year round for both the young and young at heart.
Autodesk acquired this super creative community back on August 1, 2011. Instructables is a wealth of knowledge and community of Makers and do it yourself types sharing ideas and techniques to make your ideas a reality.
There are tens of thousands of instructions created by the community covering everything from how to make robots, some 3D printing projects, some woodworking projects by Autodesk Chief maker and CEO Carl Bass, my 3D printed cabbage moth decoy to baking a cake, a nice drink, or even learning to play the bass guitar. I am always surprised at what I find on Instructables.
