README
README.mdWMRPController
DIY soldering iron controller for Weller RT tips.
There are many projects of controllers for Weller tips, but most use a DC power supply and PWM power control. This one uses AC power for the heating element. The power is controlled using zero-crossing switching, so EMI is reduced to a minimum.
I used a 3D printed handle for the RT tips, which can be found here: http://kair.us/projects/weller/diy_wmrp_handle/index.html.
This project is a playground for learning C++ on microcontrollers, so don't expect perfectly clean code ;).
What is already implemented and works well
- AC control using triac with zero-crossing switching
- PID temperature controller
- User interface
- Storing settings in EEPROM
- Storing the last set temperature in EEPROM (uses wear levelling)
- Standby and auto power off
What needs to be improved
- Temperature measurement. There is a small glitch (drop) in temperature every ~15 seconds
What is NOT going to be implemented
- Cold junction compensation of the thermocouple. This device is for hobby use only and small difference in the tip temperature is not really a problem. Adding this feature would require additional wire and a temperature sensor, which would make the cable for the handle less flexible.

Questions
How big is the WMRPControllerBoard PCB?
It measures 89.5 × 51.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the WMRPControllerBoard use?
41 parts, built around the BT138-600E, AT24CS08-SSHM-T, MOC3023M and BC337. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the WMRPControllerBoard KiCad files?
From the ekihorf/WRMPController repository on GitHub, at the commit this page was made from: the board is hardware/WMRPControllerBoard.kicad_pcb and its schematic hardware/WMRPControllerBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the WMRPControllerBoard design in my own project?
Its repository states no licence, so its author keeps all rights: ask ekihorf before reusing the design.
