“What’s up my friends, welcome back. Since I’ve reviewed the TS100 soldering iron, I’ve been working on my own portable soldering iron. So, I’ve made some tests, some research, create the PCB and finally made this project. We need a heating element to heat the iron of course. But we also need a thermocouple to read the real temperature value and then create the PID control. But using the thermocouple is not that easy, so we also need a thermocouple amplifier IC. I’ve used the MAX66 75, so I’ve bought the SMD IC so I could place it on my own PCB. This IC has a SPI port so I could communicate with it.”
