Hardware hacking is more fun with open source, DIY tools. That’s why Arhi designed a completely open soldering station controller motherboard. And we designed a through hole version that is now available as a PCB only at Seeed for $7
The completed PCB is the heart of a soldering station, able to control several types of name-brand (and clone) soldering iron pencils. The key to this universal design is the analog front-end which is capable of reading both thermocouple and PTC temperature sensors commonly used in most soldering irons.
Tip status is monitored by a mircrocontroller, and accurately adjusted via PID temperature control. Temperature, configuration, and calibration settings are shown on a 2×16 character LCD display, and controlled with rotary encoder knobs. Soldering pencils currently tested by the community include Hakko 900 series irons (most commonly cloned soldering iron), Solomon irons, and Weller PES51 irons.
- Compatible with most PTC or TC type soldering irons
- Accurate and adjustable PID temperature control
- Potential for USB data logging, and firmware updates
- UART/serial data logging
- Uses a HD44780 2×16 character LCD
- Low noise, zero crossing AC heater control
- Dangerous Prototype’s version is public domain (CC-0)
This is just a PCB. You will need to source parts, a transformer, and most importantly a suitable fuse.
This PCB is intended to be used with hot pointy things and dangerous voltages. This is a community developed board, copies are available to interested experimenters. NO SUPPORT OR WARRANTY IS AVAILABLE WHATSOEVER. This project is not recommended for everyone.
