The BoxFishOven controller supports multiple reflow, annealing, curing and drying profiles selectable from the LCD display and a design that makes it easy to add new profiles.
The target oven has two SSRs controlling the top and bottom elements (although we only turn them on/off together), a relay to control the oven's convection fan, and a PWM controlled blower that forces room air into the oven to cool it down rapidly.
Built to run on an Arduino Uno or similar with the Adafruit LCD shield and a MAX31855 thermocouple board, plus transistor/mosfet drivers for all the relays.
A built-in simulator allows the program to be tested and evaluted without any special hardware (thermocouple or relays or an oven).
