Humans didn’t come with wings from the factory, and most efforts to fit them after the fact have been at least as far as flight is concerned, largely fruitless. That doesn’t mean you can’t cut a devastatingly sharp aesthetic though, and [Natalina’s] fiber optic wings are a great way to do just that.
The wings are a leathercraft project, consisting of a harness worn around the torso. This serves as the mounting point for the fiber optics, as well as the RGB Critter flashlight used to drive the lightshow. Leather parts are lasercut to the right shape, making it easy to create the delicate feather shapes in the design. The pieces are then dyed appropriately and sewn together into the final shape. Bundles of optical fibers are then wound through the harness, sprouting from either shoulder of the wearer. EVA foam is used to help create the right shape for the wings, allowing the different layers to remain separated to create more visual depth.
It’s a build that looks absolutely striking at night, and unlike some other wing-based cosplays, doesn’t have as many drawbacks as far as crowds and transportation. It would make a killer look if you’re going as a Hacker Angel for Halloween this.
Makers certainly know how to craft some cutting-edge wearables. Got your own sweet build? Throw it at the tips line!
While there are some fixed-wing drones in the hobby world, most of us around here think of the quadcopter when this word is mentioned. There have been some fixed-wings around, and lots of multi-rotors, but not much of a mix of the two. [Paweł] wanted to see what would happen if he mixed these two together, and created a quadcopter drone with retractable wings, essentially just to see what would happen.
This isn’t something that can convert from fixed-wing flight to helicopter-style hovering like a V22 Osprey or Harrier, either. The lift and thrust is entirely generated by the rotors, and the “wings” are essentially deployable air brakes that allow the drone to slow down quickly without consuming as much energy under propeller power alone. The air brake wings are designed to automatically deploy as a function of throttle position, too, so there’s a lot that could be built on this idea in the future, in theory.
[Paweł] notes that this design is somewhat controversial, and although few of us are in the drone racing community we can imagine how a functional change like this might impact in an arena such as that. He also only saw marginal performance increases and isn’t planning on perusing this idea much further. If you’re interested in a drone with “true” wings, though, check out this one which gets fired out of a grenade launcher.

[PeterSripol] has made an RC model airplane but instead of using normal wings he decided to try getting it to fly using some KFC chicken buckets instead. Two KFC buckets in the place of wings were attached to a motor which spins the buckets up to speed. With a little help from the Magnus effect this creates lift.
Many different configurations were tried to get this contraption off the ground. They eventually settled on a dual prop setup, each spinning counter to each other for forward momentum. This helped to negate the gyroscopic effect of the spinning buckets producing the lift. After many failed build-then-fly attempts they finally got it in the air. It works, albeit not to well, but it did fly and was controllable. Perhaps with a few more adjustments and a bit of trial and error someone could build a really unique RC plane using this concept.

In recent years, Cosplay as a hobby has seen improvement in the props department by leaps and bounds. Thanks in part due to the rise of the Maker culture and the easy availability of design and manufacturing tools and processes. Case in point is this awesome set of Animatronic Wings that programmer [Nelson Stoldt] built for his daughter who wanted to be Nightmare Moon.
[Nelson] had no idea what he’d gotten himself in to when he answered “Sure, I can do that”. Making motorized cosplay wings that open up to 8 feet wide and close again at the flick of a switch without weighing a ton is not a trivial project. The final rig did end up tipping the scales at just over 9 kgs, but we guess that’s a load that Cosplayers are used to hauling around.
Using a nifty program called Linkage, he played around with a few different design approaches until he found a mechanism that worked well. If you ever want to build one of [Theo Jansen]’s Strandbeest, give this program a spin. Armed with this information, and a spreadsheet to help determine the exact length of each linkage element, he modelled the project in Sketchup. The wings are operated by a scissor mechanism that is driven by a motorized screw operated sliding carriage. Wing position is measured by a potentiometer coupled to one of the wing elements. Basically, he just built a huge, powerful servo.

It seems almost compulsory that we start off with a dose of Star Wars. Here’s an epic AT-ST build that motorizes the iconic walker.
That two-legger isn’t going to be lonely. It bigger-slower brother, the AT-AT got a bit of motorized love as well.
What? You were expecting a BB8 build? We have one of those too. [DrYerzinia] has begun a design that hides a quadcopter inside of the BB8. The four 17″ DJI propellers fold up when not in use, extending through hatches in the outer shell when it’s time to take flight. This retains the rolling design you’ve already come to love in the BB8 and we’re going to keep our eyes on it!
Do you have a Teensy and some extra WS2812 strips hanging out on your bench? [etix] put his to use with an ambilight clone. This works really well: simple hardware which connects via USB to communicate with VLC. We applaud [etix’s] choice of Kung Fury as a demo video… a truly bizarre and entertaining short movie. +1000 for its use of VHS tape artifacts.
We just missed Halloween, but this set of wings is far too great of a build to be reserved for that one day. Alas, there is only the demo video but seeing the huge feathered structures fold and unfold is really impressive!
[Truebass] added an artistic accent to one of the walls in his home. He had several cellphone chargers from old phones in his junk bin. These were used to regulate power for some white LEDs. The finished sconces are made from chip-board covered in cherry veneer, all leftover from previous projects.
Want to drink your beer out of beer-byproducts? How about your coffee out of coffee-byproducts. It sounds strange, but 3DOM is marketing it that way, encouraging you to print your beer stein with this beer-byproduct-based 3D printer filament. They also offer coffee filament and have plans for future oddball building materials. Printer inception?
We ran a post about the secret computer of the New York subway system. There wasn’t a ton of information there, but that could change. The New York Historical Society is running a Kickstarter to expand their Computing History made in NY.
Not many people will argue with flying RC airplanes is super fun. One big bummer is when a crash damages a part beyond repair. Sure, the RC pilot could keep buying replacement parts but doing so will add up after a while. RC plane builder and general guy with a cool name, [HuckinChikn], decided to build a hot wire foam cutter so making replacement wings would be quick and cheap.
The actual hot wire part is nothing special, just some wire pulled taut across a frame and a 24 vdc power supply pumping out current and heating the wire so it melts any foam in its path. The unique part of the build is that one side of the hot wire frame is secured in place and only allowed to pivot about that point. The other side of the frame traces an airfoil-shaped pattern. This setup allows [HuckinChikn] to make tapered wings. The difference between a straight wing and a tapered wing is similar to that of a cylinder and cone.
Check out the video after the break for a quick demonstration how easy it is to make a wing when you have the right tool!

At the opposite end of the spectrum from the various blimp and rigid-hull airships Goodyear has created over the years stands the Goodyear Inflatoplane, the company’s foray into experimental inflatable aircraft. Goodyear had recently created a rubberized nylon material they called Airmat, the faces of which were connected internally by nylon threads. This material was originally developed during research into the viability of emergency airplane wings.
The United States military became interested in the Inflatoplane after Goodyear had performed successful testing of demonstration model GA-33. They believed that the Inflatoplane could be dropped from the air in a rigid container to facilitate an emergency rescue, or trucked around with the rest of the cargo as a last resort for just exactly the right situation. It seems like a good idea on paper. The Inflatoplane could stay packed into a fairly small container until it was needed. The GA-468 one-seater model could go almost 400 miles on 20 gallons of fuel, and required less pressure to inflate than the average car tire.
This episode of the Discovery Channel series WINGS includes a real-time demonstration of taking an Inflatoplane from crate to air set to late ’80s montage music. It takes the pilot a full five minutes to unfurl and the plane, and he does it on a nice and level grassy spot by a lake that looks more like a cozy picnic spot than threatening enemy territory. While it’s better than not having an inflatable emergency aircraft, it just isn’t that practical.
Goodyear had all kinds of plans for future improvements, such as a vertical takeoff model and a rocket-powered version. But the Inflatoplane military initiative was grounded around the time that someone speaking for the Army deadpanned that they “could not find a valid military use for an aircraft that could be taken down by a well-aimed bow and arrow.”
