Ever wanted to roast up fresh coffee from green beans? In small batches?
Currently on the NESIT work table is a small batch coffee roaster. It’s a conversion job created from a donor popcorn popper, two thermocouples, a solid state 120v/20A switch, and an ATMega168 board. Later the popper may receive an ARM system, such as the OrangePi or Raspberry Pi, to run artisan – the coffee roasting scope. Think an osilloscope for coffee with temperature and timing software and you’ve got the idea.
