Sometimes, finding a workspace is impossible, which is why Instructables user hp07 built a workstation that can fold into a tiny little box.
The workstation includes a big set of tools, but what's really interesting about it is the fact that you can mount it to the wall and fold it away when it's not in use. When you do want to use it, the workstation folds out into its own little desk. It looks like it works well, and it doesn't take up much space. Head over to Instructables for the full guide.
