It's that time a year when winter storms begin causing havoc across the United States, and when "rotating outages" are common to help sustain the electrical grid during intense cold periods. That means pretty much anybody with snow and ice in their backyard can succumb to power outages. And no electricity means no electric heat.
I love making beeps and bloops with the Arduino pitches library, but sometimes archaic 8-bit tunes just don't cut it. Whether you want your robot to terrify your enemies with a demonic synthetic voice, you just need a pocket boom box on the go, or you want to a miniature guitar amp, a simple LM386 amplifier can crank up those signals loud enough to play through any speaker.
Building a DIY Alarm System: The Concept So, you want to protect your property, or maybe a room, car, or even your backyard. The concept of an alarm system is to notify the "alarm administrator" that there is an intruder entering the previously designated boundaries. The triggers for this boundary could be as simple as a pressure sensor, or as complicated as a laser network. They all do the same thing, but some work better than others.

Not that long ago, touchscreen-friendly gloves were an outlier accessory, something you had to track down at a specialty brick-and-mortar store or solely online. But as the smartphone has become an integral part of our lives, so, too, has the need for fashion accessories that cater to our desire to be always connected. So now, touchscreen gloves are everywhere.

About a third of the methane released into the environment comes from the production and transport of natural gas. The gas leaks as it moves along the transport chain from gas wellheads to market.
While the world is only recently becoming aware of its existence, augmented reality has been around in some form or another since the '90s. In the last decade, with the advancement and miniaturization of computer technology — specifically smartphones and tablets — AR has become far more viable as a usable tool and even more so as a form of entertainment. And these are the people behind mobile AR to keep an eye on.
In order for software developers to do their jobs as new hardware reaches the market, they will need the right tools to get their projects off the ground and into augmented and mixed reality devices. There have been completely new approaches to development when it comes to AR and MR, and these are some of the faces behind them.
Our quest to find novel compounds in nature that we can use against human diseases —a process called bioprospecting — has led a research team to a small frog found in India. From the skin slime of the colorful Hydrophylax bahuvistara, researchers reported finding a peptide — a small piece of protein — that can destroy many strains of human flu and can even protect mice against the flu.

From time immemorial, human beings seem to be at odds with one another. When these differences become so heated and unresolvable, it eventually erodes into physical violence. This violence has manifested into some of the most horrific exercises in human history, things which every school child is aware of and none of which we have to recount here. Although humans have been cruel and violent for a very long time, the 20th century may have epitomized that behavior. With two World Wars and many,...
As someone who's dependent on glasses to see on an everyday basis, losing or misplacing them is obviously a bad thing. I can't even see clearly enough to find the glasses that I just lost, so I'm pretty much blind now.

At the same time, major players are attempting to standardize various hardware designs and delivery methods, while still others are rushing to claim their piece of virtual property through AR clouds and application stores.
Fireworks are the best part about the Fourth of July and other celebrations, but they can easily cause accidental injuries. It's both safer and more fun to set them off remotely, so we'll hack some standard fireworks with nichrome wire, a relay, and an Arduino to ignite remotely over Wi-Fi using any smartphone or computer.

It's September 1st, 1859, and the Earth looks more or less like something out of an apocalyptic movie or Sci-Fi novel. All communications have failed, it's so bright outside at midnight that people are getting up and making breakfast, and people all over the world are seeing auroras.
