The Trijicon Ventus looks like a set of binoculars, but in actuality it’s the world’s first hand-held device capable of providing three-dimensional wind data at multiple points between a shooter and a target up to 500 yards (457 m) away.Continue Readin… Continue reading Ventus: The world-first hand-held 3D wind-mapping rangefinder
Weather stations are a popular project, partly because it’s helpful (and interesting) to know about the weather at your exact location rather than a forecast that might be vaguely in your zip code. They’re also popular because they’re a good way to get experience with microcontrollers, sensors, I/O, and communications …read more
A simple attack on an unpatched server could have been catastrophic for the Utah-based utility. Continue reading Solar, Wind Power Utility Disrupted in Rare Cyberattack
How many of you plan to build a wind-powered generator in the next year? Okay, both of you can put your hands down. Even if you don’t want to wind your coils manually, learning about the principles in an electric generator might spark your interest. There is a lot of …read more

Wind storms can cause a great deal of damage to coastal areas, producing waves that erode the shoreline and destroy facilities such as marinas. A newly-proposed “floating forest” could help, however, by blocking both the wind and the waves…… Continue reading Shorelines could be protected from wind and waves – by a floating forest
Building a weather station isn’t too tall of an order for anyone getting into an electronics project. There are plenty of plans online, and you can even put your station on Weather Underground if it meets certain standards. These usually have access to a reliable source of power, though, and …read more

Home weather stations are a great way for hackers and makers to put their skills to practical use. After all, who wants to hear the current conditions for the whole city when they could setup their own station which drills that information down to their very own street? Such a setup doesn’t need to be any more complex than a temperature sensor wired up to a microcontroller, but then not all of us are quite the weather fanatic that [Richard] clearly is.
The system he’s built to monitor the wind over his home is, to put it mildly, incredible. We …read more
It is three weeks after the apocalypse. No zombies yet. But you do need to charge your cell phone. How do you quickly make a wind turbine? If you’ve read this project, you might reach for a few empty water bottles. This educational project might not charge your phone without some extra work, but it does illustrate how to use water bottles to make a workable air scoop for turning a crank and possibly generating electricity.
That takes care of the wind and water aspects, but how did we get solar? According to the post — and we agree it …read more

Wind turbines are great when the wind flow is predictable. In urban environments, especially in cities with skyscrapers, wind patterns can be truly chaotic. What you need, then, is a wind turbine that works no matter which way the wind blows. And just such a turbine has won the global first prize James Dyson Award. Check out their video below the break.
The turbine design is really neat. It’s essentially a sphere with vents oriented so that it’s always going to rotate one way (say, clockwise) no matter where the wind hits it. The inventors say they were inspired by …read more
