Posted about this today at Home Barista, but posting here too. Using an old Popcorn Pumper, with Artisan running on a macbook, and an ESP32 with a TC4 to read Bean and Env Temps. Using PID function in Artisan to control the roasts. Artisan sends burner level commands to the ESP32. ESP32 controls a Crydom SSR for heater power with a PWM output. Wireless setup with Bluetooth interface between mac and ESP32. Just have to plug in power. There is a dimmer is to manually control fan power. All the project Info with a link to ESP32 software code is here: https://sites.goo...dy/roaster My ESP32 code is based on stuff I found, but I also had to add some things I haven't seen, like using the ESP32's native PWM output. Attached plot from this morning's roast, 160 grams start weight of an Eth Yirg green from Klatch
