Another yet redstone device!
This 1 is easy and not so complex.

--SET-UP---
1. place 1 RAW wood in the double chest
2. place 4 dirt in the hopper next to the furnace below the double chest(leave 1 slot open)
3. place the rest of any RAW wood on the hopper that is on top of the furnace then it will start to cook sharcoal.

Got alot of wood and dont know what to do with it? well you will have not 458904238904 RAW wood but 1 stack of wood left!
