Another take on roasting those beans

[Andrew] takes his coffee very seriously and like any hardcore aficionado he wanted to do the roasting himself. The coffee roaster design uses a heat gun for the roasting and sources an old bread maker as a vessel. As part of the automatic bread making process there’s a little agitator arm inside which keeps the beans moving while the heat is applied. A computer controls the heat gun, adjust with feedback from a temperature sensor. We had a bit of a laugh reading about melted temperature sensors, but design flaws aside this computer interface allows rather strict control of the roasting profile.

Reader [Youseff] tipped us off about this after seeing the Popcorn Coffee Bean roaster from last week.
