Open Soldering Station PCB

Hardware hacking is more fun with open source, DIY tools. That's why Arhi designed a completely open soldering station controller motherboard. 
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 2x16 character LCD display, and controlled with rotary encoder knobs. Soldering pencils currently tested by the community include Hakko, Solomon irons, and Weller PES51 irons. See a full list of tested soldering pencils.
Features

• 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 2x16 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.
WARNING
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 anyone.
