Although the decision to create a DC-AC power inverter using a microcontroller can be somewhat divisive, Danish enthusiast Michael has gone ahead and done just that. It's a relatively simple design based around an Arduino-compatible circuit which could be used to generate mains power from solar cells, car batteries and other portable sources. If you're interested in doing it yourself the sketch, schematics and notes have been provided. In the following video a quick demonstration of the output voltage is given:
An interesting application for Arduino that could be quite useful. Please note that working with mains power can be lethal, so consult a licensed electrician. Otherwise visit the project page for more information (opens in Google Translate). And for more, we're on twitter and Google+, so follow us for news and product updates as well.
If you're wanting to reproduce the project above - you'll need a an ATmega328P MCUs with Arduino Uno bootloader:
This is the same Atmel AVR ATmega328P microcontroller used in the official Arduino Uno, as well as our Eleven, EtherTen, USBDroid, and other boards. Perfect for building your own Arduino-compatible project directly on a breadboard or on a custom PCB, or for replacing the MCU in an existing board. Comes with the Arduino Uno bootloader pre-installed. Better still, it even has a special label stuck on top with details of the pinout, so you don't even need to look up the datasheet when connecting it up in your project!
