Will John Deere Finally Get Their DMCA Comeuppance?

When it comes to activism, there are many different grades of activist aside from the few who you may encounter quietly and effectively working for change in their field. There are the self-proclaimed activists who sit in their armchairs and froth online about whatever their Cause is, but ultimately aside from making a lot of noise are pretty ineffectual. Then there are the Rebels With A Cause, involved in every radical movement of the moment and always out on the streets about something or other, but often doing those causes more harm than good. Activists can be hard work, at times.

If you are within whatever Establishment that has aroused the collective ire it is not the screamers and banner-wavers that should worry you, instead it is the people who are normally quiet. When people who spend their lives getting things done rather than complaining turn round en masse and rebel, it’s time to sit up and take notice. If people like the farmers or the squaddies are on the streets, the probability of your ending up on the wrong side of history has just increased exponentially and maybe it’s time to have a little think about where you’re going with all this.

The video below the break follows a group of Nebraska farmers fighting for the right to maintain their farm machinery, in particular the products of John Deere. Since all functions of a modern Deere are tied into the machine’s software, the manufacturer has used the DMCA to lock all maintenance into their dealer network. As one farmer points out, to load his combine harvester on a truck and take it on a 100-mile round trip to the dealer costs him $1000 every time a minor fault appears, and he and other farmers simply can’t afford that kind of loss. We’re taken to the Nebraska State Legislature and shown the progress of a bill that will enshrine the right to repair in Nebraskan law, and along the way we see the attempts by lobbyists to derail it.

We normally write Hackaday stories in the third person, but it’s worth saying that this is being written from a small farming community in Southern England, and that there is a green and yellow tractor parked outside somewhere. Thus it’s from first-hand experience that you can be told that Deere is in danger of becoming a damaged brand among its staunchest supporters. They still make damn fine tractors, but who wants to be caught with brief weather window to get on the land, and a machine that’s bricked itself? It’s hardly as though Deere are the only manufacturer of agricultural machinery after all.

This video is quite important, because it is a step towards the wider story becoming more than just a concern to a few farmers, hardware hackers, and right-to-repair enthusiasts. The last word should go to one of the farmers featured, when he points out that all his older tractors are just as capable of going out and doing the same day’s work without the benefit of all the computerized technology on their modern siblings.

Travel In Style On An Electric Air Sled

What do you do during the winter months in Ohio? Sledding of course! Sledding normally takes place on hills, but [Peter Sripol] is no slave to the terrain. He’s built an air sled to conquer the barren wastelands of unplowed parking lots. Air sleds aren’t as outlandish as you might think — the Soviet Union had decades of success with them.

The project starts with toboggan style plastic sled. [Peter] built a frame into the plastic using an aluminum square. The frame is used to support a motor pod at the back of the sled. The motor, of course, comes from his DIY electric plane project. Don’t worry — [Peter] didn’t cannibalize his plane. The plane’s motors are being upgraded, and this is one of the originals.

The motor itself is quite a beast. It’s a 150cc equivalent brushless outrunner motor from HobbyKing. It’s not cheap either at around $450 USD.  The motor is controlled by an equally beefy brushless controller wired into a standard R/C car receiver. A pistol grip transmitter makes a great wireless throttle for the system.

Steering is a much more mechanical affair. The sled’s rudder is controlled much like that of an airplane. A steel cable pull-pull system is connected to a stick mounted in front of the pilot. The unreinforced styrofoam rudder turned out to be a weak point in the build — check out the video after the break to see the full story.

Smaller And Smarter: The Electron Rocket Takes Flight

On January 21st, 2018 at 1:43 GMT, Rocket Lab’s Electron rocket lifted off from New Zealand’s Mahia Peninsula. Roughly eight minutes later ground control received confirmation that the vehicle entered into a good orbit, followed shortly by the successful deployment of the payload. On only their second attempt, Rocket Lab had become the latest private company to put a payload into orbit. An impressive accomplishment, but even more so when you realize that the Electron is like no other rocket that’s ever flown before.

Not that you could tell from the outside. If anything, the external appearance of the Electron might be called boring. Perhaps even derivative, if you’re feeling less generous. It has the same fin-less blunted cylinder shape of most modern rockets, a wholly sensible (if visually unexciting) design. The vehicle’s nine first stage engines would have been noteworthy 15 years ago, but today only serve to draw comparisons with SpaceX’s wildly successful Falcon 9.

But while the Electron’s outward appearance is about as unassuming as they come, under that jet-black outer skin is some of the most revolutionary rocket technology seen since the V-2 first proved practical liquid fueled rockets were possible. As impressive as its been watching SpaceX teach a rocket to fly backwards and land on its tail, their core technology is still largely the same as what took humanity to the Moon in the 1960’s.

Vehicles that fundimentally change the established rules of spaceflight are, as you might expect, fairly rare. They often have a tendency to go up in a ball of flames; figuratively if not always literally. Now that the Electron has reached space and delivered its first payload, there’s no longer a question if the technology is viable or not. But whether anyone but Rocket Lab will embrace all the changes introduced with Electron may end up getting decided by the free market.

IoT Doorman: Eye-Controlled Door For A Girl With Cerebral Palsy

Kyleigh has an eye-controlled computer on her wheelchair but something as simple as her bedroom door was still beyond her reach… until now! [Bill Binko], recently filmed a demo of an automatic, IoT door opener built for the young girl with cerebral palsy. [Bill] is a co-founder of ATMakers, an organization that enables makers interested in assistive technologies to collaborate with users to improve quality of life.

Using her eye tracking tablet (PRC Device), Kyleigh has two new icons that make the relevant call to a website, pushing a simple command to either open or close her bedroom door. The device attached to the door uses an Adafruit M0 WiFi Feather board, a DC stepper motor and wheel, a UBEC buck converter, and a potentiometer.

Since other family members are also going to be opening and closing the door, there’s potentiometer which measures the door position for proper operation next time Kyleigh wishes to use the door. The installation also maintains a fairly inconspicuous profile for the assistance it gives — the ‘brain’ is enclosed in a small box on the door, with the motor only slightly larger on the door’s base.

[Bill] believes the project has a few quibbles and wants to work out a smaller wait before the open/close process is executed and optimizing the open/close speed. You have to check out the video below to see that it works really really. We’re also excited to see Kyleigh using her gaze control to talk to an Amazon Echo. [Bill] foresee a door control improvement that links it to Alexa. And how much did it cost to improve the quality of life for this young girl? $70.

We love seeing makers help people, and cannot wait to see what 2018 will bring! If you’re looking for more inspiration, don’t miss the eye-controlled wheelchair project called Eyedrivomatic which won the 2015 Hackaday Prize. There’s also the top Assistive Technology projects from the Hackaday Prize.

Asgard: The Open Source Air Data Computer

We get a lot of awesome projects sent our way via the tip line. Well, mainly it seems like we get spam, but the emails that aren’t trying to sell us something are invariably awesome. Even so, it’s not often we get a tip that contains the magic phrase “determine Mach number” in its list of features. So to say we were interested in the Asgard Air Data Computer (ADC) is something of an understatement.

Now we’ll admit right up front: we aren’t 100% sure who the target audience for the Asgard is, but it certainly looks impressive. Team member [Erik] wrote into tip line with information about this very impressive project, which is able to perform a number of measurements on incoming air, such as true speed, viscosity, and temperature. The team says it has applications ranging from HVAC to measuring the performance of bicycles. We don’t know who’s going so fast on their bike that they need to measure air speed, but of course the hacker community never ceases to amaze us.

Even if you don’t have a jet fighter that could benefit from a high performance ADC such as Asgard, you have to be impressed by the incredible work the team has done not only designing and building it, but documenting it. From the impeccably designed 3D printed case to the stacked PCB internals, every aspect of Asgard screams professional hardware.

Data collected from Asgard can be stored on the internal micro SD if the device is to be used in stand-alone mode, or you can connect to it over USB or Bluetooth thanks to the HC-05 module. The team has even put together some scripts to merge the Asgard’s generated air data with GPS position information.

We’re all for putting high quality sensors in the hand’s of the community and seeing what they can come up with. The spirit and build quality of this project reminds us of the impressive work [Radu Motisan] has been doing with his distributed air quality sensors.

Wrecked Civic Rides Again As Cozy Camp Trailer

It may not be the typical fare that we like to feature, but you can’t say this one isn’t a hack. It’s a camp trailer fashioned from the back half of a wrecked Honda Civic, and it’s a pretty unique project.

We don’t know about other parts of the world, but a common “rural American engineering” project is to turn the bed and rear axle of an old pickup truck into a trailer. [monickingbird]’s hacked Civic is similar to these builds, but with much more refinement. Taking advantage of the intact and already appointed passenger compartment of a 1997 Civic that had a really bad day, [monickingbird] started by lopping off as much of the front end as possible. Front fenders, the engine, transmission, and the remains of the front suspension and axle all fell victim to grinder, drill, and air chisel. Once everything in front of the firewall was amputated, the problem of making the trailer safely towable was tackled. Unlike the aforementioned pickup trailers, the Civic lacks a separate frame, so [monickingbird] had to devise a way to persuade the original unibody frame members to accept his custom trailer tongue assembly. Once roadworthy, the aesthetics were tackled — replacing the original interior with a sleeping area, installing electrics and sound, and a nice paint job. Other drivers may think the towing vehicle is being seriously tailgated, but it seems like a comfy and classy way to camp.

Now that the trailer is on the road, what to do with all those spare Civic parts? Sure, there’s eBay, but how about a nice PC case featuring a dashboard gauge cluster?

3D Printed Hovercraft Takes Flight

Last time we checked in on [Ivan Miranda] he was putting a drill press on the Internet. Lately, he has been trying to 3D print a hovercraft with some success. He made four attempts before arriving at one that works fairly well, as you can see in the video below. We will warn you, though, the screwdriver cam is a bit disconcerting and we suggest waiting at least an hour after you eat to watch.

The starboard impeller broke midway through the test, although with a single impeller it was working pretty well. [Ivan] thinks he can print the impeller frames more strongly to prevent future failures. The design is in Fusion360 and there is enough detail that you can probably duplicate his work if you have the urge. There’s a mount for a headlight and an action camera on the bow.
