Skiing with a drone

A few weeks ago I got a present from my IETF friends: a Mavic Pro drone. Thank you! We've already played a lot with it, me, Olli, Janne, and many of our friends, with everyone having loads of fun with the device!

Although there's a lot to learn for drone newbies. Olli even got interested enough to order parts for his own open-source drone.

And it is an amazing device. I've tried some copter toys before, but this one is the first one that is actually easy to fly. It does exactly what you want it to do via the controls, and if you let it go it stops right there, whatever the speed, be there wind or not.

It flies automatically back home, and recognises precise landing spots through video. The radio range is impressive 7 kilometres, and the drone flies roughly 25 minutes on a single charge. The basic drone controls are on a dedicated device that attaches to your own smart device. The smart device is the user interface for the more advanced functions, shows video feed from the drone, locates the drone using a map, and so on. I'm using my iPad mini for this purpose.

And some of the tech in the drone is even scarily powerful. You can click on a person on the screen and have the done follow it merely based on image recognition. The above was a somewhat disturbing clip of the scary people-following tech inside this drone.

These advances functions are powered by the drone's 8 CPUs, having altogether 24 cores. Shortly after starting the drone, its powerful internal fans need to start cooling the electronics :-)

Of course, the one application I had in mind was skiing. We've now tested it a couple of times in the closed ski areas nearby. First in Peuramaa, when Kauniainen was still surprisingly open last weekend. And this weekend then in Kauniainen. The snow conditions are by the way excellent, all slopes still fully covered in good snow.

In Peuramaa, the golfers are already taking over, there were many people golfing right next to the slope. Summer is coming, I guess. (But I'm glad no one got a drone-in-one shot!)

The Mavic Pro shoots 4K video and the default settings produce the views as they were, in high-quality and without burning out or underexposing any of the details. The drone has a number of automatic modes, from following its controller on GPS to tracking based on image recognition and automatic lift-off and return-to-home features. The image-recognition-based tracking modes can also have the drone fly on the side of the target or circle it, with camera pointed to the target at all times. We have not tested all of those modes yet though. Initial experiences from the basic video-based follow mode indicate that snow is a good high-contrast environment to ensure that the drone can see the target clearly, but that the drone needs some manual control in addition to the automation to adjust flying altitude as the skier descends.

Here's a clip from our first test of shooting skiing in the automatic follow mode, in Peuramaa's a bit cloudy day. The drone is here in completely automatic mode, following me based on the recognising the skier on its video:

And then in Kauniainen, on a slightly more sunny day, and with some additional manual control in addition to the automation we took this clip:

(IN) Spire - Bird Completes a First Descent Down Liberty Bell Mountain’s North Face

Witness an historic first descent between some of the most iconic spires in North America. Bird fulfills a dream to complete a pure ski descent of a long sought after dream and lays turns down Liberty Bell Mountain massif's north face. Its easy to see why he named it (IN)-spire, as this jewel of a run is literally hanging between the spires. Hold on and take a ride with me. You might wish that i had brought my wing.  Maybe next season eh?  hehe. Full wingspan -Michael Bird

Mad Trees’ The Falcon Celebrates A Special Flavor of Van Life

Admit it, your vehicle says a lot about you. Especially if it’s the kind of vehicle that frequents the Mount Baker Ski Area parking lot. Enter Sophia Rouches and her Ford Falcon camper van. These things popped up in the late 80s and early 90s, and a surprising amount of them are still running just fine, taking skiers like Rouches to the zones of their choice. Of course, Rouches likes nothing more than to bring her friends along for the ride – no matter how uncertain it might be, given the

Behind The Line – Caite Zeliff Vs. The Cave Air

The Jackson Hole backcountry is filled with a bucket list of classic mega-airs, and it’s turned into a rite of passage for any young ski talent to start checking them off. For North Face athlete Caite Zeliff, the season spent filming for was full of days dedicated to working through that list. One air, in particular, stood out though – the infamous Cave Air, which had seen some of the masters of the sport put tracks down it. With inspiration from the likes of Sam Smoothy, Lynsey Dyer,
