This is a more simpler design than the DIY SMD SOLDERING STATION WITH AVR (MEGA2560 VERSION) due to the controller core (Arduino NANO instead of MEGA2560), the UI (a 4 rows / 20 characters LCD instead of the TFT) and the supporting of only PTC type soldering irons. The power supply is still separated (external power pack at 24V used).
All the information for the user is presented continuously and simultaneously for the actual temperature and desired temperature by the form of bargraph and numbers. For the present, only the Celsius scale is supported but I am still working on updated version with Fahrenheit scale and a very simple menu function for making the adjustments.
The final view of this simple construction is like the following:
I made all the necessary files for the PCB and a good friend of mine (Kostas), the order for ten prototypes. The design was a clear Through Hole project in order to be easily constructed as kit even from young people. In the near future, I will write a very easy-to-read guide for assembling and programming.
I thank Kostas for the kind offer of the prototype PCB and also the spread of this project to other friends.
The schematic is the following (also in .pdf):
The PCB is the following:

UPDATE 14 AUG 2016:
The updated version of the soldering station is a new design with the implementation of an Arduino Micro PRO instead of Nano. The overall dimensions have been reduced and the code was re-written to support a small serial I2C OLED display.
