Arhi compares his soldering iron driver with commercially available products. After designing and building a open source soldering station 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
arhi posted the final update on his universal soldering pencil driver: This is I think “final” version of this design. 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 […]
HAKKO soldering pencil driver update
arhi posted an update on his HAKKO soldering pencil driver: The driver actually works like a charm – if you take the “numbers” on display as some “arbitrary value” and not temperature in C :D. The tip temperature is held pretty good and it all works great, it’s just that “values” are meaningless. The 500C […]
HAKKO soldering pencil driver
arhi made a control board for HAKKO soldering pencils. Add a power supply, probably from an old PC, and you have a quality DIY soldering station. From the project log forum: Upgrades from v1 1. thermocouple is read properly. The circuit used to get the K-type to go 0-5V came from microchip’s app note 2. […]
