After going to an SMD soldering workshop at the Stuttgart hackerspace ShackSpace, [Corvus] decided to be an over achiever and build a flight controller for his very own unmanned aerial vehicle.

The airplane itself is a regular store-bought foam contraption, and not terribly interesting in and of itself. Autonomous flight piques some interest, though. A custom flight controller PCB was designed and built by [Corvus] to work alongside a tiny STM32 Linux board. These two boards, combined with the OpenPilot project allow the plane to keep altitude, bearing, speed, and position in check autonomously. Telemetry between the ground station and vehicle is handled by UAVTalk and a ThinkPad.

In the video after the break, [Corvus] piloted the plane up to altitude, then directed it to fly 500 meters North and turn around. The result was an autonomous flight of over one kilometer. The next stage of the project is implementing some SLAM applications with optical path finding and obstacle avoidance.

Imagine our surprise when we learned [Bruce Simpson], who made headlines in 2003 with his $5000 DIY cruise missile, is still alive, not illegally interned in a black ops prison, and still doing what he does best: building really awesome remote-control airplanes.

The first successful mass-produced pulse jet aircraft was the German V-1 flying bomb. The V-1 had a very primitive guidance system, but the unmanned pulse jet aircraft quickly evolved into a few target drones used by the US Air Force. There was never any significant advancement towards improving the fuel consumption, noise level, or heat signature of pulse jets, so they were superseded by the superior turbojet. Despite their failings, pulse jets are remarkably easy to build and amazingly fast.

Instead of being antagonized by the New Zealand and United States governments, [Bruce] spends most of his time now working on pulse jet projects. He’s flown quite a few modified R/C planes and has an electronic Engine Control Unit for his jets. One of his most impressive projects is the 100 pound thrust pulse jet that was later attached to a go-kart. His no weld version of a pulse jet can be built in even the most minimalist work shop and is the epitome of an easy-to-build jet engine.

To get an idea of how fast [Bruce]‘s planes can be, check out his Long-EZ R/C pulse jet in action after the break.

If you had the pleasure of attending last year’s DEFCON conference, you are no doubt familiar with [Mike Tassey] and [Richard Perkins]. There, the pair showed off a work in progress DIY aerial drone named WASP. Short for Wireless Aerial Surveillance Platform, WASP was impressive when we brought it to your attention last year, but the duo has spent some time completing their project, adding a few extra features in the process.

The drone still packs the same pico-ITX computer which now runs Backtrack5, and utilizes a 340 million word dictionary for cracking WiFi networks (pardon the pun) on the fly. While updated pen testing tools are well and good, the most impressive update is that the drone can now act as a standalone GSM tower. This allows the pair to trick nearby phones into routing calls through WASP before being relayed to their carrier’s network.

Once WASP is launched, the plane flies autonomously along a preset route, sniffing, hacking, cracking and gathering data until [Tassey and Perkins] summon it back to Earth. The drone is as impressive as it is scary, and we can’t wait to hear what the pair has to say about it this time around.

Continue reading to watch a video demo of WASP taking to the skies and doing its thing.

Controlling a long-range unmanned aerial vehicle is much easier if you have an augmented reality system like [Fabien Blanc-Paques] built. On board the aircraft you’ll find a sensor suite and camera, both transmitting data back to the operator. As the title of this post indicates, the display the operator sees is augmented with this data, including altitude, speed, and a variety of super-handy information. For instance, if you get disoriented during a flight there’s an arrow that points back to home. There’s also critical information like how many milliamp-hours have been used so that you can avoid running out of juice, and GPS data that can be used to locate a downed aircraft. Check out some flight video after the break.

The WiFi Aerial Surveillance Platform, or WASP for short, is an autonomous drone aircraft that sniffs out WiFi networks. But it packs a much larger punch than that. Built into this US Army surplus target drone you’ll find an ITX form-factor computer with a Via C7 500 MHz processor that is running Backtrack 4, the popular penetration testing Linux suite. But what if you want to do some real heavy lifting that the onboard PC can’t handle quickly? They’ve thought of that too. There’s an integrated 3G modem which allows for control over the Internet and facilitates the outsourcing of load-intensive operations to the cloud. It’s not shooting fireworks from the wings, but this payload has the potential to cause way more trouble.

[Karl-Engelbert Wenzel] developed a UAV capable of taking off and landing on a moving platform autonomously. The platform operates aircraft-carrier-style by driving around the room in circles. The quadcopter tracks a grid of IR LEDs at the front of the landing deck by using the IR camera from a Wii remote. The best part is that the flight controls and processing are all done by the copter’s onboard ATmega644 processor, not requiring a connection to a PC. The landings are quite accurate, achieving a maximum error of less than 40 centimeters. In the video after the break you can see the first landing is slightly off the mark but the next two are dead on target.

So build yourself a mobile platform and pair it up with your newly finished quadcopter to replicate this delightful hack.

An unemployed electrical engineer can be a very dangerous thing. [Cybrown] has turned his skills toward darker, more awesome applications by building an armed unmanned aerial vehicle. This is a remote control airplane that has a movable camera mounted in the cockpit. Video and GPS data are sent back to the pilot who views the picture via a wearable display. We’re betting this doesn’t have the range that the 100km UAV did, but that’s good because this one brings doom from the skies. Check the wings in the picture above, this RC is fireworks-enable. We’ve embedded flight footage and attack video after the break.

Update: Here is a forum post covering this nugget of awesome. There are just a few details but the entire thread is interesting. Someone pointed this out in the comments but they don’t get credit because they didn’t leave a link.

[Jack], [Cory], and [Maciej] are playing Pac-Man with Roombas on a lab floor. The Roombas are outfitted with ALIX3d2 single board computers running Gentoo and a software suite developed for UAVs at the University of Colorado at Boulder’s Research and Engineering Center for Unmanned Vehicles. The hardware and software sections are quite in-depth and make for a good read.

[Terence Bordelon] sent in his impressive UAV (Unmanned Arial Vehicle). The hack is a culmination of his other projects. It can be turned to fully automatic at the flip of a switch. It will fly itself to gps way points, land, and take off. The UAV has a range of 100km thanks to his home built RF Unit which runs on ham bands. The brains of the setup is his custom IMU (Inertial Measurement Unit). The unit is controlled by his ground station which either allows him to fly it normally or toggle through the various modes.  [Terrence] is also a game developer and has worked on many popular titles such as Zoo Tycoon 2 and Ratchet and Clank.

These Autonomous Underwater Vehicles are all competing in the 12th annual AUVSI competition. They have to complete an underwater obstacle course that involves some tight maneuvering, retrieval of a briefcase, dropping bombs, and firing torpedoes. We’ve seen several UAVs before, but we haven’t ever seen them weaponized and in action. Yeah, those weapons don’t look lethal, but isn’t that just a matter of ammunition?

The first talk of ShmooCon was [Ethan O'Toole] and [Matt Davis] presenting their OpenVulture software for unmanned vehicles. In the initial stages, they had just planned on building software for Unmanned Aerial Vehicles, but realized that with the proper planning it could be used with any vehicle: airplanes, cars, boats, and subs (or more specifically, their Barbie PowerWheels). The software is in two parts. First is a library that lets you communicate with each of the vehicle’s modules. The second half is the actual navigation software.

They’ve spent a lot of time sourcing hardware modules. They are looking for items that work well, aren’t too expensive, and have a fairly plug and play implementation. For their main processor, they wanted something that wasn’t a microcontroller and could run a full Linux system. The ARM based NSLU2 NAS seems to be the current frontrunner. You can find the opensource software and descriptions of the supported modules on their site.

They’re building the first test UAVs now. One has a 12 foot wingspan for greater lift and stability. We’ve covered the Arduino based Ardupilot and other UAVs in the past.

The Ripsaw MS1 is an unmanned ground vehicle built by two brothers in Maine. The tracked vehicle can go 0-60 in 3.5 seconds with an 80mph top speed. In its current form, it has a 2000 pound capacity, which opens the possibility for many different types of weapon systems. Control is provided by two people: one driver and one gunner. They work in independent remote stations. The Ripsaw could potentially be used in any application normally reserved for a tank. It could lead a charge without putting soldiers at risk.

We’ve been watching this project mature since 2005 when it was being marketed as a Grand Challenge competitor. This week it’s being demoed at the Army Science Conference. Check out footage of it in motion below.

The Cambridge Autonomous Underwater Vehicle, built for the SAUC-E Challenge, is a fantastic example of UAV construction. The competition is to build a UAV that can complete an underwater assault course. This baby has a full computer inside it, based off of the worlds smallest full featured x86 motherboard, the Pico-Itx.  It has a 1GHz EPIA PX 1000 Board, 1 GB of RAM, Wireless Network capabilities and runs Ubuntu server 8.04.

The CUAV suffered from leaks which ultimately cost it the competition, but the information on the build is fantastic. They have detailed pages upon pages of information about the Mechanical, Electronic, and Software aspects of the design.  They even went back in and added notes from what they learned during the competition.  The project is also outlined in much shorter form on the mini-itx website.

Usually, when someone mentions military drones, we think of something much smaller and less intimidating than this monster. This is an Airforce Phantom II, retrofitted to be a computer controlled killing machine. Able to carry 18,000 pounds of stuff that goes boom, a single computer can control up to 6 of these in formation.

Sounds scary doesn’t it?  Actually, though these are capable of being offensive, they are mainly used for target practice. These are decommissioned units that have been fixed up and modified to be radio controlled.

We wrote about [Chris Anderson] before when he released the Arduino based autopilot. He has since crashed his first Predator UAV, due to an underpowered motor and poor control of the v-tail only steering. He has since released a pro version of the autopilot controller, and is modifying this UAV Predator drone kit to work with it. One ATMega168 processor handles flying and the other handles GPS navigation, but because they work together, it results in a fully autonomous drone. He also has a BlimpDuino version we have covered before.
