This project is called a "wood gasifier camping stove". It's a portable, homemade stove, of the gasifier type. This means, that the thing you're heating is heated by hot gas that's created by the burning of a fuel source, in this case it's wood.
You'll need two food cans, one larger than the other. I used an empty ravioli can and a large can that held either peaches or pie filling. You need to keep the lid to the larger can and remove it with a safety can opener if you have one. If not, use a regular can opener sideways. The top rim needs to stay in tact. As far as tools, I did mine without anything electric, but if you have a drill, it'll make things a whole lot easier. I used a piercing type can opener (sometimes called a church key), an awl (kinda like an icepick), tin snips, pliers, and a grinding stone.
