SMD Soldering Station for Weller Soldering Tips [140010-I]

The project is about a cheap SMD solder station built as an Arduino shield (Arduino UNO). It supports active soldering tips from Weller (RT series) which contain the heating element as well as a sensor and provides a standard 3.5 mm jack. Together with the corresponding female connector you will get a compact SMD soldering iron with very fast heat up times of a few seconds. The shield consists of a low-noise amplifier for measuring the temperature via the ADC of the AVR, a power MOSFET stage to control the heating using PWM and a 7-segment LED display and push buttons for setting and displaying the temperature. The controller is realized digitally on the AVR. Further information can be found at: http://www.martin-kumm.de/smd_solder_station

this project is crying out to be ported to a standalone AVR micro!
BASCOM AVR would be perfect for the firmware.
the circuit could be smaller and cheaper to build;as the only 'extras' required would be a 5v supply to support the AVR and the op-amp.

This project cannot be published in Elektor due to exclusivity issues.
We would like to port it to Platino and publish it that way. What do you think?

Hi Martin,
great work!
It's ideal to work with a car supply of 12V for outside using.
What type of temperatur sensor have the Weller RT series?

I also say : nice project. What power supply are you using?
Why not using a ATmega328 PRELOADING and program with RS232 interface ?

Looks good, really a nice project. What power supply are you using?
It will be (a lot) less expensive than a Weller soldering station, but you could still save on the costs if you replace the Arduino board with just a microcontroller.
