HAKKO soldering pencil driver update

Arhi compares his soldering iron driver with commercially available products. After designing and building a open sourceĀ soldering stationĀ for Solomon or Hakko soldering pencils, he posted a full analysis of his project. While his driver has some overshoot, once it stabilises the temperature has less swing then the original drivers. With some PID tuning even better […]

Final universal soldering iron driver update

Not much to be done here (except change the mcu and then push more functionality to it). It works, the Solomon handle works perfectly (Ktype thermocuple sensor) and the HAKKO (ptc sensor) works satisfactory (I’m […]

The tip temperature is held pretty good and it all works great, it’s just that “values” are meaningless. The 500C […]
