I knew about this when it came out, but it never made it’s way to Hack-A-Day. We’ve mentioned a computer controlled roaster before, but this one is far and away the best I’ve seen. [Jeffrey Pawlan] has been selling individual units to the coffee industry (and extreme coffee geeks) – with good reason. He modified an already sweet Hottop coffee roaster (~$500 US) to be completely computer controlled. He wrote a complete software interface that accounts for room temperature to create complex, repeatable roast profiles. More than anyone, I’ve lamented the lack of details on the system. It’s a safe bet that he’s using more than a few thermocouples with a multi-line A/D converter. Anyone feel like writing some open source coffee roaster software? Modifying my current setup wouldn’t be that difficult.
