Vaavud plugs into your smartphone’s headphone jack to take quick and accurate wind speed measurements wherever you are, whenever you need them. This simple and durable design stands up to the elements.
Why We Love It
The basic design has been around for hundreds of years, but Vaavud is still a feat of modern engineering. With absolutely no electric parts (even the part you plug into the headphone jack is just a plastic mount), Vaavud uses the air around you and the technology in your phone to give precise wind speed measurement readings from 2 to 56 miles per hour on the fly. As its arms spin in the breeze, the magnetometer in your phone detects the field created by the two magnets embedded in the Vaavud’s rotor. The app then converts the rotations of these magnets into wind speed using modified sound processing algorithms. It’s a totally unique use of the sensor (normally applied in compass apps) and a brilliant solution to a tricky problem!
Vaavud’s all-plastic body makes it incredibly durable and lightweight. With no metal parts or delicate electronics inside or out, it can stand up to continued use even in the rain or salty ocean spray (it’s also compatible with some waterproof phone cases like the Optrix). Vaavud is dirt- and sand-resistant, and comes in a little drawstring neoprene bag for packing or storage. The two-arm design gives it a low profile when stowed so you can safely toss it in your bag or clip it on your hip without worrying about snagging or snapping.
We’re offering the Vaavud in either red or white. Both colors include replacement base pieces for use with the Samsung Galaxy S2 - just go to vaavud.com/support for installation instructions.
The Vaavud has been confirmed for use with the following hardware:
iPhone 4, 4s, and 5
iPad 2, 3, 4, and Mini
Samsung Galaxy S2, S3, and S4
The Vaavud app is just as clean and easy to use as the peripheral. Hit “Start” and Vaavud will instantly begin recording and graphing wind speed data over time. When you have your sample, just hit “Stop.” The line graph shows you variance in speed during the sample and draws a mean average. You can scroll horizontally through the graph and even pinch to zoom in and out of specific parts. Up above, the app displays the mean, actual, and max wind speeds. Tap on the unit to cycle instantly between mph, kt, m/s, and km/h. The Vaavud team is hard at work on ways to share all of this data, including integrating Vaavud measurements into Weendy, the world’s fastest growing social network for real-time weather reports.
Why We Love It
We love technology, but we also love getting outdoors. A new piece of technology to take on our adventures is just the best of both worlds. It’s a practical tool that’s fun and easy to use, and small, lightweight, and tough enough to bring anywhere.
It’s also one of those great data gadgets that just makes you want to measure things. With no windsurfing trips on the calendar, we found ourselves busting out the Vaavud to measure whatever we could, just because we could! A breeze down Third Avenue, the rush of wind as the subways pulls into the station, even the differences between the low, medium, and high settings of a window fan. At home, it made for some fun rounds of “Who can sustain the highest speed the longest” while blowing into the Vaavud.
