A nice gadget for your Iphone to check how much wind there is at your spot:



Have you ever wondered how strong the wind is, exactly at the spot where you are? If you are a kitesurfer or windsurfer like us, then the answer is probably yes. But perhaps as a sailor, paraglider, model aircraft pilot, etc. etc. you would also like to get a precise reading of the wind, right on the spot? Then the Vaavud wind meter is just what you need!

The Vaavud wind meter enables you to take precise and reliable measurements of the wind anywhere, using your iOS or Android phone. And of course you can share your measurements online, and see live wind readings from other users on a map. So Vaavud can help you plan your trip, choose the right gear when you get to the spot, and alert others of the conditions before they go.

The Vaavud wind meter contains no electronics, but still connects wirelessly to your phone... Wait, what ??

Yes, you read it correctly :-) The secret is two small magnets in the rotor. The magnetic field sensor in the phone can detect when they rotate, and by using algorithms normally used for sound processing, the rotations can be converted to wind speed. Complicated engineering, made user friendly and simple. In fact, nobody has utilized the smartphone magnetometer in this way before.

The device has been very thoroughly tested and it has been calibrated in a wind tunnel at The Technical University of Denmark. It will be manufactured with keen attention to detail, so it will great looking, durable, and easy to use.

To realize this project we need to make a significant investment in production tools, and meet minimum order requirements - so we need your help! Please back our project, and share it with your friends.
