Tearing An Old Laptop Apart To Build A Ground Control Station

August 31, 2013 by Mathieu Stephan 53 Comments

Being tired of assembling and disassembling parts/cables every time he went outside to fly his plane, [Elad] figured that he’d be better off building his own ground control station.

The core of the station is based on an old laptop with a broken screen he had laying around and (luckily) an older laptop screen he had found. As the latter only accepted LVDS, an adapter that could generate theses signals from the standard laptop’s VGA output was needed. [Elad] therefore disassembled his laptop and fit all the parts in a Pelican case he bought, as well as a lead-acid battery, a 12V to 19V stepup converter (to power the laptop), temperature/voltage/current sensors with their displays, 40mm fans, an AC/DC converter to charge the battery and finally a pico-UPS to allow uninterrupted use of the station when switching between power sources.

Because [Elad] didn’t have access to any machinery, PVC foam was used to maintain all the parts in place. Autonomy of his station is around 2.5hours on a single 12V 7Ah battery.

FPV Drones With An Oculus Rift

July 16, 2013 by Brian Benchoff 21 Comments

It was only a matter of time, and now someone’s finally done it. The Oculus Rift is now being used for first person view aerial photography. It’s the closest you’ll get to being in a pilot’s seat while still standing on the ground.

[Torkel] is the CEO of Intuitive Aerial, makers of the huge Black Armor Drone, a hexacopter designed for aerial photography. With the Rift FPV rig, the drone carries a huge payload into the air consisting of two cameras, a laptop and a whole host of batteries. The video from the pair of cameras is encoded on the laptop, sent to the base station via WiFi, and displayed on the Oculus Rift.

Latency times are on the order of about 120 ms, fairly long, but still very usable for FPV flight. [Torkel] and his team are working on a new iteration of the hardware, where they hope to reduce the payload mass, increase the range of transmission, and upgrade the cameras and lenses.

Turning Anything Into A Drone

For his graduate project, [Jasper] wanted to do something with a quadcopter drone. Not content with simply building any old drone, he decided to make a kit that turns anything into a drone. Everything from a bicycle wheel, to a computer keyboard, and even a phone is more than able to take flight with [Jasper]’s Drone It Yourself kit.

The DIY drone kit consists of a few 3D printed parts that include four clamps and mounts for the four engines. Also on board are ESCs, a battery, receiver, and an OpenPilot autopilot that will hopefully keep a drone in any shape imaginable hovering in the air. All this packaged in a sleek aluminum briefcase make it look like something out of an eccentric Bond film parody.

This project isn’t for sale – at least until the Brookstone catalog steals the idea – but you can get the bill of materials directly from [Jasper], just in case you’d like to make your own random flying object.

An Autonomous Boat Across The Atlantic

July 8, 2013 by Brian Benchoff 42 Comments

While we may be waiting for unmanned drones to deliver a pizza, there’s already an unmanned ship plying the Atlantic on a transoceanic voyage. It’s called Scout, and it’s the product of about two years worth of work by a very close-knit group of friends.

Scout is a 12.5 foot ship constructed out of foam and carbon fiber loaded up with solar panels, electronics, an electric motor and a SPOT satellite tracker. The team has been working on Scout for the last two years now, and this last week the autonomous ship finally set out on its mission: a 3500 mile journey from Rhode Island across the Atlantic to Spain.

Right now, Scout is just over four days into its mission having travelled 90 miles from Rhode Island on its way to Spain. You can follow Scout on its journey on this very cool live tracking site.

The Thunderball Jetpack Becomes A Quadcopter

At the beginning of the fourth Bond film, 007 escapes from a French château with a jetpack. While the jetpack has yet to take off for those of us who aren’t secret agents, there is a way for anyone to fly just like Bond. It can’t lift a full-scale human yet, but [Rodger]’s Project Thunderball can let a mannequin hover for several minutes.

The stand in for [Sean Connery] in [Rodger]’s build is a 2.2 lb mannequin – actually an ‘inflatable companion’, if you will – stuffed with styrofoam peanuts. The actual jet pack is a quadcopter souped up with larger motors, propellers, and enough batteries to deliver 1kW. There’s no belt for this quad; the mannequin rides the machine like you would a horse, straddling the electronics while very high-speed props spin just inches away from the tender bits of an inflatable plastic doll.

[Rodger] is able to get about 8 minutes of hover time out of his quadpack, an impressive feat that also allows his flying machine to deliver beer and pizzas.

Giving An Electric RC Plane An Afterburner

March 25, 2013 by Eric Evenchick 40 Comments

The folks at Flitetest decided to add some extra power to an electric DH.100 Vampire RC plane by adding a butane afterburner. After some testing, and a bit of fire, they were able to make it fly.

Their afterburner uses a small butane canister for fuel. A servo motor actuates the valve on the canister, forcing fuel into a tube. This tube is set up to regulate the flow of butane and ensure it vaporizes before reaching the afterburner.

At the afterburner, a circular piece of tubing with holes is used to dispense fuel, much like a barbecue. This tube is connected to one side of a stun gun’s flyback generator, and the metal surrounding it is connected to the other. The stun gun creates sparks across the gap and ignites the fuel.

With the extra components added, the landing gear was removed to save weight and the plane was given a nice coat of paint. They started it up for a test run, and the plane’s body caught fire. After some rework, they managed to take off, start the afterburner, fly around, and belly land the plane. It achieved some additional thrust, but also sounds and looks awesome.

After the break, check out a video walkthrough and demo. We promise you fire.

DIY Arduino Pro Mini Quadcopter

March 19, 2013 by Ryan Fitzpatrick 5 Comments

[execUc] took a stock V929 quadcopter and started making some crafty customizations. The main change – the control electronics were replaced by an Arduino Pro Mini (16Mhz model). He soldered all the modules on a prototyping board and, although admittedly a bit heavy, the little guy takes flight with no problem.

Among other details, an HMC5883L (magnetometer) and MPU6050 (accelerometer / gyroscope) are used as sensors. A LiPo 7.4V battery pack supplies the power. The brushed motors are controlled by pulse-width modulation from SI2302 MOSFET with added diodes. He plans to swap out the micro-controller for an ARM7 stm32F103 for extra computing power, and needs to play with the PID values to correct a slight problem he seems to be having when rotating.

Check out a test flight video after the break. [execUc] has a thorough list of all the alterations he made in the video description, so be sure to read it.
