Lightning Damage Costs Double for Electronics
The cost of insurance claims for lightning strikes nearly doubled between 2004 and 2011, and insured losses reached $1 billion last year alone according to a study by the Insurance Information Institute. The National Lightning Detection Network recorded nearly 23.4 million lightning flashes nationwide in 2011, but the rising cost isn’t entirely to do with the weather. In fact, … [Read more...]

College Students’ Satellite to Help NASA Learn More about Solar Flares
A group of Arizona State University engineering and business students have been working on the Sun Devil Satellite 1 project since 2009 to help advance NASA’s knowledge about solar flares and their effect on Earth’s magnetic field. Solar flares can be signs of the formation of gigantic solar storms, which can propel powerful electromagnetic bursts of charged particles from the … [Read more...]
Scientist Builds Tesla Gun that Fires Sparks
Self-confessed “mad scientist” Rob Flickenger has created a Tesla-inspired gun based off of images from the graphic novel The Five Fists of Science. The cover of the graphic novel features an image of a young Tesla holding several weapons containing Tesla coils. Flickenger designed and constructed his Tesla-inspired gun over several months and claims to have “tapped Seattle’s … [Read more...]

Fundamentals of EMC Design: Our Products Are Trying To Help Us
INTRODUCTION We often design electronic products only to find that when we test them for electromagnetic compatibility (EMC), their emissions and/or immunity are not as good as we need them to be. Usually, at this time, we feel as if we are fighting against the laws of physics to contain the conducted and radiated emissions, or to reduce susceptibility. But in fact the laws of … [Read more...]
