ATtiny 85 EMF detector
arduinomaster @ instructables.com has build an EMF detector based on ATtiny85 mcu able to detect signals from 0-999Hz. He writes: An EMF meter can measure AC electromagnetic fields, which are usually emitted from manmade sources such as electrical wiring, while gaussmeters or magnetometers measure DC fields, which occur naturally in Earth's geomagnetic field and are emitted from other sources where direct current is present.
