Simple Arduino EMF detector

Friday, May 24th, 2013

Here's a simple Arduino EMF detector  by Aaron ALAI: This is an improved version of an Arduino EMF detector from Aaron ALAI. It uses one resistor and a piece of wire to detect if there is any EMF (elector-magnetic field) around. Nice and simple idea! Via PCBheaven.

More projects using Altoids tin boxes as enclosures

Monday, September 17th, 2012

In response to our "Disposable metal boxes make excellent shielded enclosures" app note post, Sverre shared some of his projects using the same enclosures. They are mostly RF projects, benefiting from the tin enclosure's EMF protection. Nice post which triggered me to picture some of my own Altoid projects. Via the...

Arduino EMF detector

Saturday, January 1st, 2011

High electromotive force/electromagnetic field (EMF) readings can cause interference with precision electronic equipment, and have even been associated with paranormal/spirit activity! DTN's blog has an Arduino project designed to detect high EMF levels. It uses an Arduino mega with a 4 inch wire antenna on pin 31 and 16 LEDs...
