Our new wind meter

Wind is an important factor for a wide range of activities, but the greatest places in the great outdoors are far away from any weather station. In order to give you precise and sharable wind readings on the spot, we created the first Vaavud wind meter and launched it here on Kickstarter. People loved it!

Now we are back to launch the world's first handheld wind meter that actually measures wind direction, as well as of course wind speed.

This is made possible by our unique asymmetrical rotor design (for further details scroll down to the technical stuff).

We have gone through countless iterations on the rotor design and we have obsessed about every little line and detail, to make sure that both performance and looks are second to none.

The Vaavud app

The new device will work with the popular Vaavud app, which features the world's first real-time graph on a handheld wind meter; a global live map; your personal measurement history and much more to come.

             

Device compatibility

Currently we have confirmed the new device to work with the following phones and tablets, and the list keeps growing!


*iPods do not have a compass, so on those the app will show wind speed, but not wind direction

Timeline

We are working towards a shipping date in November 2014, and so far all is set to achieve that target

Rewards

Stretch goals

Colour choice: The third colour will be the one that gets the most votes from all backers, once the campaign is over. More info on this will follow when we get there

Mount + data export: The mount will be printable on most common 3D printers, and will be designed to work with a standard jack-stick extender cable. The design files will be made available, so you can do all the modifications you want to. The data export feature will upload a time series for each measurement as a CSV file to a dropbox folder of your choice

Special carry case: This will be a neoprene hard case similar to the ones known from Oakley sunglasses etc. but tailor made to the Vaavud wind meter. We are quite happy with the current neoprene bags, but this will be something special; a snug fitting, robust, exclusive case made just for your Vaavud V2.0

Welcome on board!

Our Kickstarter legacy

Comments from backers and press about our first Kickstarter campaign

The technical stuff

We are using an optical sensor that measures 40.000 times per second, so we can detect even the slightest variation in rotation speed. By making the rotor of the wind meter slightly asymmetrical we get it to accelerate a bit when the largest part is hit by the wind. We can then compare the point with the highest speed to the compass direction and derive the wind direction. At the same time, data from the highly accurate sensor can be used to derive the average rotation speed and thereby the wind speed.

The graph below shows the change in velocity during one full rotation for one of our prototypes. For this one the difference in speed is a bit more than 3%, and the maximum speed is reached at about 45 degrees from start.

Risks and challenges

Any hardware project faces risks - there is no denying that. But we are at a point, where we have eliminated practically all technical risks, so now it is a matter of getting the final design details in place, source the components, and get production started.

Things can of course get delayed in the production process, because rework is needed after seeing the initial production samples, or because a component from a sub-supplier is delayed or turns out not to be in the right quality etc. etc. etc.

However, we learned a lot from launching our first product here on Kickstarter. It went pretty smooth, but we can also see lots of big and small things that we can improve. Furthermore we have teamed up with a great design & engineering company here in Denmark, to help us with finding and managing suppliers - something they have a lot of experience with. So we are doing everything we can, to identify any bumps on the road well in advance, and on managing our way around the ones that will inevitably appear.

Furthermore we have our entire logistics set-up in place. This is one of the biggest headaches for a hardware project, with backers from all around the globe. But we have this up and running, so even if production gets delayed, we should be able to absorb all or most of it, because our shipping will run smoothly.
