Whether you call them UAVs (Unmanned Aerial Vehicles), UAS (Unmanned Aerial System), Drones, or something less polite – people are more familiar than ever with them. We’ll call them drones, and we’re not talking about the remote-controlled toy kind – we’re talking about the flying robot kind. They have sensors (GPS and more), can be given a Flight Plan (instructions on where to go), and can follow that plan autonomously while carrying out other instructions – no human pilot required. Many high-end tractors are already in service with this kind of automation and we’ve even seen automated harvesting assistance. But flying drones are small and they don’t plant seeds or pull weeds, so what exactly do they have to do with agriculture?
There are certain things that drones are very good at, and there are things in agriculture that are important but troublesome to do or get. Some of these things overlap, and in those spaces is where a budding industry has arisen.

This Thursday, December 10th at 5pm PST we will be hosting a live HackChat about aircraft. If it’s man-made and it files, it’s on topic! Full scale and model planes, helicopters, multicopters, gyros, blimps and gliders will be on the agenda. Our host this week will be Hackaday Community Editor [Adam Fabio] who is also the author of this well-written blog entry. In addition to being an electrical engineer, [Adam] brings 30 years of experience as a Radio Control model enthusiast. Over the years he’s worked as a professional R/C Blimp Pilot for the New York Islanders Hockey team and as an aerial photographer. On the full-scale aircraft side, he’s designed radar and air traffic control software used to keep the skies safe over land and sea.
Aircraft HackChat starts Thursday at 5pm PST (here’s a timezone cheat sheet if you need it). Participating in this live chat is very simple. Those who are already part of the Hacker Channel can simply click on theTeam Messaging button. If you’re not part of the channel, just go to the hacker Channel page, scroll to the bottom of the “TEAM” list in the left sidebar and click “Request to join this project”.
HackChat takes place in the Hacker Channel every few weeks and is a friendly place to talk about engineering and the projects you’re working on.
L.A. artist [Jonathan Fletcher Moore] sent us this fantastic tech-art piece on dehumanization and drone warfare. Talking too much about art is best left to the artists, so we’ll shut up and let you watch the video below the break.
The piece is essentially a bunch of old cap guns with servos that pull their triggers. A Raspberry Pi with an Internet connection fetches data on US drone strikes from www.dronestre.am and fires off a cap every time someone is killed. At the same time, the story version of the data is printed out in thermal paper that cascades onto the floor.
Viewers are encouraged to sit underneath all the cap guns and wait. Talk about creepy and suspenseful. And a tiny reflection of the everyday fears that people who live under drone-filled skies.

This homemade glove and gesture controlled rover was created by [electro18]. It can send temperature, battery level, and object distance to the LCD panel on the wrist. Instead of a typical joystick, this wireless system taps into an embedded accelerometer to maneuver the robot like magic.
The main chassis platform is made of clear acrylic and has additional acrylic strips fixed to the edges for additional strength. A LM35 temperature sensor is wired to the front that monitors the environments that the rover explores. An HC-SR04 Ultrasonic Rangefinder acts as the eyes of the machine. The photodiode is covered with an adaptation of a 6mm heat shrink tube to avoid false readings. Once hooked up and turned on, the robot can be controlled with the futuristic power glove consisting of two parts. An accelerometer strap and a display strap are the biggest parts. The project shows that it is relatively easy to make a system like this. Other items like quadcopters and tiny water boats could be controlled with a similar type of setup.
A video of the axis glove maneuvering the vehicle on a slope can be seen after the break:

North Korean drones! Yes, your local hobby shop has the same aerial reconnaissance abilities as North Korea. Props to Pyongyang for getting v-tail mixing down.
There’s nothing quite as satisfying as the look of a well laid out resistor array, and the folks at Boldport have taken this to a new level. It’s an art piece, yes, but these would make fabulous drink coasters.
Here’s something even more artistic. [cpurola] found a bunch of cerdip EPROMs and bent the pins in a weird chainmaille-esque way. The end result is an EPROM bracelet, just in time for mother’s day. It’s a better use for these chips than tearing them apart and plundering them for the few cents worth of gold in each.
[John] still uses his original Xbox for xmbc, but he’d like to use the controllers with his computer. He never uses the third and fourth controller ports, so he stuck those in his computer. It’s as simple as soldering the controller port module to a connector and plugging it into an internal USB port. Ubuntu worked great, but Windows required XBCD.
[Kerry] has modified an FT232 USB/UART thingy as an Arduino programmer before. The CP2102 USB/UART is almost as popular on eBay, a little less expensive, and equally suited for ‘duino programming. It requires desoldering a resistor and soldering a jumper on a leadless package, but with a fine solder tip, it’s not too bad.
The world is buzzing about drones right now. Even we’re joining in the fun with some antics of our own. Right now, it is basically a legal free-for all since no one is enforcing regulation, but is that about to change? Should it?
Lets start off by establishing the definition of a “drone”. For this article, we’ll settle for any “unmanned aerial vehicle”, though we can all agree that that limiting this to airspace is fairly restrictive. This is the specific type that are making the news right now and quite possibly catching the eye of people who make the rules.

There is no shortage of government and entertainment-related agencies chomping at the bit to shut down the Pirate Bay for good. While the group has not suffered a permanent service ending raid like [Kim Dotcom] and the Megaupload crew, they are always thinking up novel ways to ensure that the site can endure whatever law enforcement throws at them.
In a recent blog post, representatives from the group unveiled plans to put their front line servers in the clouds, courtesy of custom-made autonomous drones called “Low Orbit Server Stations.” The project is in its infancy, but the general idea is to mount small computers like the Raspberry Pi on GPS-controlled drones kept aloft 24×7 (presumably) using solar energy. These drones would communicate with clients on the ground via radio transmitters which they state can provide a “100Mbps node up to 50km away”.
Calling the claims grandiose would be an understatement, but then again the Pirate Bay has proven to be a difficult organization to quash in any substantial way, so only time will tell.
