Ski areas are setting formal policies for drones left and right, but what happens when your drone isn’t a drone but is instead a tethered iPhone with wings swinging around you like a ball-and-chain flail as you careen down a mountain? [nicvuignier] decided to explore the possibility of capturing bullet-time video of his ski runs by essentially swinging his phone around him on a tether. The phone is attached to a winged carrier of his own design, 3D printed in PLA.
One would think this would likely result in all kinds of disaster, but we haven’t seen the outtakes yet, and the making-of video has an interesting perspective on each of the challenges he encountered in perfecting the carrier, ranging from keeping it stable and upright, to reducing the motion sickness with the spinning perspective, and keeping it durable enough to withstand the harsh environment and protect the phone.
He has open sourced the design, which works for either iPhone or GoPro models, or it is available for preorder if you are worried about catastrophic delamination of your 3D printed model resulting in much more bullet-like projectile motion.

Several of us got Cheerson CX-10 mini quadcopters last year. We even bought some more to hand out as Christmas gifts. If you haven’t seen them, they are diminutive little flyers about the size of an English muffin. Thee’s no denying they are fun to fly around the house, and they do annoy the dogs.
However, like all cute toys, you eventually get bored just buzzing the dogs and cats. [JustforFun Media TK] decided that his needed a facelift, so he converted it into a paper airplane. This isn’t the paper airplane you folded up in school, either. This is a slick-looking jet aircraft.

We have to be impressed by [amazingdiyprojects] who completely totaled their manned multi-copter build, which has been spanning over eight videos. He explained the crash in video number eight and is right back at it, learning from the recent mistakes.
When you get right down to it, this is as dangerous as this seems. However, a giant multicopter is probably the easiest flying machine for a hobbyist to build. It’s an inefficient brute-force approach, but it sure beats trying to build a helicopter from scratch. This machine is a phenomenally un-aerodynamic chair on a frame that has a lot in common with the lunar rover; with engines on it. Simple.
There are a lot of approaches to this. One of the crazier ones is this contraption with a silly amount of electric motors. [amazingdiyprojects] went with eight gasoline engines. We’re really interested in his method for controlling the rpm of each engine and dealing with the non-linearity of the response from a IC engine throttle. Then feeding that all back into what is probably the exact same electronics from a regular diy drone.
Honestly, we’re surprised it worked, and we can’t wait for him to finish it so we can see him zooming around in his danger chair. Videos after the break.
Thanks [jeepman32] for the tip!

Late last year, the FAA expanded a Special Flight Rule Area (SFRA) that applied to Unmanned Aerial Systems, drones, and RC airplanes around Washington DC. This SFRA was created around the year 2000 – for obvious reasons – and applies to more than just quadcopters and airplanes made out of foam. Last December, the FAA expanded the SFRA from 15 nautical around a point located at Reagan National to 30 nautical miles. No remote-controlled aircraft could fly in this SFRA, effectively banning quadcopters and drones for six million people.
Today, the FAA has rescinded that ban bringing the area covered under the Washington DC SFRA to 15 nautical miles around a point inside Reagan National. This area includes The District of Columbia, Bethesda, College Park, Alexandria, and basically everything inside the beltway, plus a mile or two beyond. Things are now back to the way they were are few weeks ago.
The 30-mile SFRA included a number of model flying clubs that were shuttered because of the ban. DCRC is now back up. The Capital Area Soaring Association worked with the FAA and AMA to allow club members to fly.
Of course, limitations on remote-controlled aircraft still exist. For the most part, these are rather standard restrictions: aircraft must weigh less than 55 pounds, fly below 400 feet line of sight, and must avoid other aircraft.
A lot of people got drones for Christmas this year (and many Hackaday readers already had one, anyway). A lot of these drones have cameras on them. The expensive ones beam back live video via RF. The cheaper ones just record to an SD card that you can download later.
If you are NASA, of course, this just isn’t good enough. At the Langley Research Center in Virginia, they’ve been building the Greased Lightning (also known as the GL-10) which is a 10-engine tilt-prop unmanned aerial vehicle. The carbon fiber drone is impressive, sure, but what wows is the recent video NASA released (see below).

According to this report at FOX News Technology, the FAA may use “deadly force” against your remote-controlled quadcopter, ahem, “drone” if you’re flying within a 36-mile radius of the Super Bowl this weekend. We call shenanigans on using “deadly” for things that aren’t alive to begin with, but we have no doubt that they intend to take your toys away if you break the rules. We are curious to see how they’re going to do it, though.
The actual Notice to Airmen (NOTAM) has the details, and seems pretty comprehensive. You can’t fly your sea plane or go crop dusting either. Model rocketry is off the table within the circle on Sunday afternoon. It tickles our superiority-bone to note that only “drones” made the headlines.
But we also see our loophole! The ban only extends from the ground’s surface up to 18,000 ft (5,500 m) above sea level. (No, we’re not thinking of flying quadcopters in tunnels under the stadium.) They didn’t rule out high-altitude balloon flight over the Super Bowl? Don’t even think about it.
On the other hand, those of you near the game should count your blessings that you don’t live within 30 miles of the US Capitol and spend the day drone racing.

Rutgers University just put out a video on a “drone” that can fly and then drop into a body of water, using its propellers to move around. This isn’t the first time we’ve covered a university making sure Skynet can find us even in the bathtub, but this one is a little more manageable for the home experimenter. The robot uses a Y8 motor combination. Each motor pair on its four arms spin in opposite directions, but provide thrust in the same direction. Usually this provides a bit more stability and a lot more redundancy in a drone. In this case we think it helps the robot leave the water and offers a bit more thrust underwater when the props become dramatically less efficient.
We’re excited to see where this direction goes. We can already picture the new and interesting ways one can lose a drone and GoPro forever using this, even with the integral in your toolbox. We’d also like to see if the drone-building community can figure out the new dynamics for this drone and release a library for the less mathematically inclined to play with. Video after the break.
