Dog Bowl Coffee Roaster

Dog Bowl Coffee Roaster Make 2
Create a coffee roaster with stuff you may already have at home! Via Make:

Here’s a cheap, quick, and reliable machine that roasts a decent amount of coffee beautifully with only 5 main parts: two $9 Black & Decker screwdrivers, a $15 heat gun, a cheap power supply and, oh yeah, a (new) dog bowl.

Various incarnations of the heat gun/dog bowl technique are well documented online. This one takes the concept to the next level. It’s easy to build in a day or two, quick to roast, and, best of all, the roasting process is automated, reliably exposing the entire surface of every bean to the same heat.
