Summary of DIY Arduino Soldering Station
This project shows how to build an Arduino-based soldering station for a standard JBC soldering iron, covering thermocouples, AC power control, zero-cross detection, parts sourcing, and a 3-part 3D-printable enclosure. A companion video provides core instructions and the article supplies extra details and component links.
Parts used in the Arduino based soldering station:
- Toroidal Transformer
- 2x 2W10 Full Bridge Rectifier
- BTB26 Triac
- MOC3020 Optocoupler
- 4N25 Optocoupler
- Arduino Pro Mini
- SPI OLED LCD
- MAX6675 thermocouple amplifier
- 2x 1000µF Capacitor
- 3x 100Ω Resistor
- 1x 330Ω Resistor
- 1x 2kΩ Resistor
- 50kΩ Potentiometer
- 3-part 3D printed enclosure (123D Design file)
In this project I will show you how to create an Arduino based soldering station for a standard JBC soldering iron. During the build I will talk about thermocouples, AC power control and zero point detection. Let’s get started!
Step 1: Watch the Video!
The video gives you all the basic information you need to build a soldering station. In the next steps though I will present you additional, helpful information.
Step 2: Order Your Components!
