Soldering station to drive HAKKO 907 handles

Dilshan Jayakody published a new build: To keep it simple we choose LM358 dual operational amplifier IC to monitor the 907’s thermocouple and drive the TRIAC. The entire control circuit of this soldering station is powered by single rail 5V DC power supply. To drive both handle and station we use 12V-0-12V 8A step down […]

Review of the Hakko FX-888 soldering station

John reviews the Hakko FX-888 soldering station. It’s the latest iteration of one of the most cloned soldering stations, the Hakko 936. The stations are simple and sturdy, with a wide selection of tips. The tips are backward and forward compatible, 900M tips fit the FX-888 and the T-18 tips fit older 936 stations. Although […]

Open source soldering iron driver test videos

Arhi made some videos of his open source soldering iron driver tests. SID is capable of driving any soldering iron with RTD or ThermoCouple sensor. In this video I’m testing the HAKKO soldering iron and a HAKKO clone iron made by GORDAK. In the next test he compares the heater/sensor readings to the actual tip […]

Soldering iron driver update

Arhi continues to develop the universal soldering iron driver. This is a rendering of the third generation PCB. The soldering iron driver can use soldering pencils with K-type or PTC type temperature sensors like Solomon, Hakko, and Weller, to name a few… Generation 3 has a reworked analog section. It that now fully supports PTC […]

Soldering iron tip selection guide from Hakko

Arhi contacted us about this useful guide for selecting the right size and shape tip for your soldering iron. First part of the article compares various diameter tips used over the same soldering point. Graphs show that for the fastest work-flow is when using larger or same size tips as the solder point. The second […]

HAKKO soldering pencil driver update

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 […]
