Mecha Turbo Crazy coffee roaster


I’m a wee bit of a coffee geek. This roaster was built by [farmroast]. It’s a highly modified of version of the roaster that I’ve been using for the last year or so. A convection oven up top provides the primary heat source, while the beans are spun around in the roast chamber below. A pair of thermocouples let you know what’s going on inside the chamber. When the roast is done, pop the top, dump the beans into the drawer, and a fan mounted below cools them to room temperature in about a minute. It was put up for a home roaster building contest – You might be interested in the other entries.

I hope the coffee wars at defcon are this interesting.
