An easy to use graphical reflow controller for your toaster oven. Source files available on github. by Unexpected Maker:
Reflow Master really started out as a microcontroller-based graphing experiment… I wanted to visualise the temperature in my toaster oven when I manually reflowed my PCBs.
I had a K-Type probe in my oven connected to my digital multimeter, and though I could see the temperature, unless I also used a stopwatch, I had no real idea of how long I was reflowing for and at what temperature… it was VERY scientific.
So I thought about using a MAX31855 module connected to a micro-controller to read the temp from my probe and simply drawing this as a graph of temperature over time on a small TFT screen also connected to the micro-controller.
