This driver can be used with Weller tips which have integrated heater element and temperature sensor. More precisely, tips from WMRP (soldering pen) and WMRT (soldering tweezers) series can be used. Hardware is kept as simple and cheap as possible while still trying to give special attention to usability and accuracy.

Here is a demonstration video of the station in action and overview of the various functions:

Features

Supports Weller WMRP and WMRT tips
Very quick heat-up time and response
Supports WMRP bare tips (with 3.5mm stereo plug)
Supports the original Weller cables/handles, including readout of PTC for cold junction compensation and reed switch for in-stand detection
Accurate temperature readings with auto-zero opamp
Mains frequency filtering for noisy environments
Setback temperature, setback delay, standby, offset settings as in original Weller stations
Possible to change step size and temperature unit (°C or °F)
Diagnostics functions to show thermocouple temperatures from both tips of WMRT, cold junction PTC temperature, reed status and recognized tip type
Uses internal reference of microcontroller. Possible to calibrate it with multimeter and diagnostic menu setting.
All functions controlled with one knob

For more information, design files, firmware, source code, see the project web page at http://kair.us/projects/weller/index.html
