Roast Your Own Coffee Beans With A Drill!

If you're a coffee enthusiast, you've probably looked into roasting your own coffee beans at some point or the other. Well, Tim Eggers is a coffee nut and he used $10, a soup can, and a drill to jury-rig his own coffee bean roaster, now that's cool!

We've never thought about using a drill, but it looks like Tim's contraption works very well. It takes about 13 minutes to roast 100g worth of beans. The key to this build is to keep the beans moving so that you get an even roast. While Tim was pondering this, he decided to use his drill to see what would happen.

His drum was made from a soup can. He cut and added vanes so that the beans would tumble around, getting a better chance of an even roast. Another soup can was used to focus the heat from his stove-top burner. You can check out this forum for more variations on his idea, but all in all, the basic idea stands.

This is definitely an innovative idea to roast your own beans. It's cheap and easy enough so that everyone can try it out, which is why we really like it a lot.
