Gerrit and I were scoping out the Intel booth at Bay Area Maker Faire and we ran into Nolan Moore who was showing of his work to mash together a Nintendo Power Glove with an AR Drone quadcopter. Not only did it work, but the booth had a netted cage which Nolan had all to himself to show off his work. Check the video clip below for that.
The control scheme is pretty sweet, hold your hand flat (palm toward the ground) to hover, make a fist and tilt it in any direction to affect pitch and roll, point a finger up or down to affect altitude, and point straight and twist your hand for yaw control. We were talking with Nolan about these controls it sounded sketchy, but the demo proves it’s quite responsive.
The guts of the Power Glove have been completely removed (that’s a fun project log to browse through too!) and two new boards designed and fabbed to replace them. He started off in Eagle but ended up switching to KiCAD before sending the designs out for fabrication. I really enjoy the footprints he made to use the stock buttons from the wrist portion of the glove.
A Teensy LC pulls everything together, reading from an IMU on the board installed over the back of the hand, as well as from the flex sensors to measure what your fingers are up to. It parses these gestures and passes appropriate commands to an ESP8266 module. The AR Drone 2.0 is WiFi controlled, letting the ESP8266 act as the controller.
Quadcopters are gradually becoming more affordable and thus more popular; we expect more kids will unwrap a prefab drone this holiday season than any year prior. [Samy’s] got plans for the drone-filled future. He could soon be the proud new owner of his own personal army now that he’s built a drone that assimilates others under his control.
The build uses a Parrot AR.Drone 2.0 to fly around with an attached Raspberry Pi, which uses everybody’s favorite Alfa adapter to poke around in promiscuous mode. If the SkyJack detects an IEEE-registered MAC address assigned to Parrot, aircrack-ng leaps into action sending deauthentication requests to the target drone, then attempts to take over control while the original owner is reconnecting. Any successfully lassoed drone doesn’t just fall out of the sky, though. [Samy] uses node-ar-drone to immediately send new instructions to the slave.
You can find all his code on GitHub, but make sure you see the video below, which gives a thorough overview and a brief demonstration. There are also a few other builds that strap a Raspberry Pi onto a quadcopter worth checking out; they could provide you with the inspiration you need to take to the skies.

[Max Ogden] wanted the option to add sensors to his Parrot AR Drone. This a commercially available quadcopter which runs Linux. This makes it rather easy for him to use Node.js to read the sensors from an Arduino board. The use of the Arduino is merely for easy prototyping. It is only needed to bridge the drone’s serial port with a sensor’s delivery method, so just about any microcontroller could be substituted for it.
There are some hardware considerations to take into account. The manufacturer was nice enough to populate a 0.1″ pitch pin socket on the serial port (if only this kind of invitation to mess with hardware was an industry standard). But the device expects 3.3V levels so pick your hardware accordingly. There is one commenter who tried the project for themselves and found that the drone wouldn’t boot up with the Arduino already connect — he had to boot and then complete connections. Troubles aside this makes adding your own sensor payload very simple and you don’t have to wait until landing to get at the data.
Maybe we’ll have to add some shock voltage data reporting to our shockerDrone.
You’ve all seen taser like devices built from disposable cameras. We have seen them mounted to rubber gloves, finger tips, even potato gun ammo! We had not yet seen them on a quadcopter. This was quickly remedied once we had one to play with. Meet the shockerDrone, a Parrot AR Drone with built in shocker attachment.

As I mentioned earlier, we’ve got an AR Drone to play with. One of the common mods that popped up on the internet were ways of extending the range on the AR Drone. It normally uses a local Wi-Fi connection to your phone or tablet for control and video signals. Many found this quite restrictive and have gone pretty far in extending that range.
The first and easiest was just to set up a higher power Wi-Fi Bridge where you’ll be flying. The Drone only has about 15db of wi-fi magic in it, so anything stronger than that is an improvement. There were too many variations on this to delve into the details, but as you see, there’s not much too it.

Ever since we played with the original AR drone back at CES a few years ago, we’ve been keeping an eye on them. While we all agree there are better quadcopters out there, the price point for a ready-to-fly quadcopter of this size is really great with these.
When the fake video from FPS Russia of the weaponized drone made the rounds earlier this year, we were surprised at how people reacted. Anyone who has messed with quadcopters recognized it as fake right off the bat (not to mention the overly cliche fake russian character).
We won’t be adding a full fledged firearm to this. Mainly because it simply can’t lift the weight (There are ones that can, but we couldn’t justify the cost just for that). We do have some ideas though.
Lets go over the specs of the AR Drone 2.0 first.
