In this video, I show you the prototype of my reflow hot plate. The hot plate is just a simple "desoldering heating plate" that you can buy from popular webshops. However, the coding part, especially the graphical user interface (GUI) is much more sophisticated. I created a fancy GUI that allows the user to enter any arbitrary reflow curve and then run the program and follow the development of the temperature in realtime. The circuit also has a MAX6675 thermocouple module for measuring the temperature and a simple BD139based transistor circuit that switches on two tiny fans at the end of the program to speed up the cooling/solidification process.

In the upcoming videos, I will put these things on a proper PCB and further improve the coding part and will try different heaters.
