Self-Assembly Kits

I am planning to offer a self-assembly kit. This will include the PCB, all parts, cable and connector for the solder tip. The price of the kit is 35,- Euro. Optionally, I can offer an Arduino for 15,- Euro.

If you are interested in the kit, the Arduino or the solder tip (35,- Euro), please contact me with a short mail via mail-at-martin-kumm.de.

Project Description

This page provides documents 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 (see pictures below) 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.

Hardware and software are open source.
