This project provides firmware and schematics for a simple solderstation based on the RT tips from Weller, which can be connected through a standard 3,5 mm jack.
The electronic is mostly based on the original project from Martin Kumm. Most notable differences: The user interface is simplified (no display, just some LEDs and buttons) and a (optional) circuit for protection against a PWM freeze is added.
The firmware is a complete rewrite for Arduino Uno.
The used PID module is Brett Beauregards Arduino PID library with some minor formatting adjustments.
For PWM generation Sam Knights Arduino PWM frequency library is used.
