A month ago, Hackaday landed at the NYC TechCrunch Disrupt, a bastion of people up all night on MacBooks and immense amounts of caffeine and vitamin B12. For 20 hours, everyone was typing away trying to build the next great service that would be bought by Google or Amazon or Facebook. Tucked away in one small corner of the room was the Hackaday crew, giving out dev boards, components, and advice to the few dozen hardware hackers at Disrupt. [David], one of these Hackaday enthusiasts won the Twilio Sponsorship Prize at Disrupt, and now it’s a Hackaday Prize entry.
[David]’s dad has a little bit of paranoia of accidentally leaving the stove on. This usually manifests itself a few minutes after leaving the house, which means turning the car around just to make sure the stove was off. At the TechCrunch hackathon, [David] built a small IoT device to automatically read the temperature of the stove, send that off to the Internet, and finally as an SMS via Twilio.
The hardware [David] is using is extremely minimal – a thermopile, a gas sensor, a WiFi module, and a microcontroller. There’s a lot of iterations in this project, with [David] looking at everything from TI MSP430s to Teensys to Arduinos to ESP8266 modules. Still, rough prototype thrown together in 20 hours is all you need to win the Twilio prize at Disrupt, and that’s more than enough for a very good Hackaday Prize entry.

Normally, when we talk about companies and institutions looking to silence security researchers and their ilk who have tried to expose potential threats, the story ends without tragedy. United Airlines, for instance, went on the attack on Chris Roberts, who may well be an idiot, for exposing in-flight WiFi security concerns. CyberLock decides to go legal on a researcher who had been trying desperately to contact them about a security flaw in a number of its electronic locks. Johns Hopkins, meanwhile, ordered the disappearing of a blog post detailing how its own servers might be compromised by the NSA (or used with permission) to defeat encryption schemes.
But in all of those cases, even if some shenanigans were had, there was no real damage done as a result of ignoring the security advice that those organizations subsequently attempted to silence. So, what is the consequence of ignoring that device? Well, as it turns out, the consequence is anus. Very, very, tragically, unfortunately infamous anus.
The affluent denizens of Atlanta’s Buckhead neighborhood received a fun treat this week when they looked up at the corner of Peachtree and East Paces Ferry: a famous internet man’s giant, ruddy, gaping spread asshole, displayed on an enormous digital billboard.Great, so because whoever is in charge of managing that electronic billboard couldn't be bothered to take the advice any competent technology person who came across the setup, of which there must have been at least one, the great people of Atlanta were treated to one of the most disgusting images in human existence. I'm generally loathe to blame the victim, but the owner of a public-facing billboard must have some culpability when it comes to securing their display. And I say that there was at least one person who warned them about this, because at least one has come forward publicly.
The billboard above [Techdirt editor: which I'm not posting, because obviously I'm not] is one of the thousands of YESCO digital billboards installed across the country. Naturally, it comes with an internet connection. The setup is exactly as insecure as you’d imagine: many of these electronic billboards are completely unprotected, dangling on the public internet without a password or any kind of firewall. This means it’s pretty simple to change the image displayed from a new AT&T offer to, say, Goatse.
Not only was this a case of incompetence, but gross negligence: security researcher Dan Tentler tweeted yesterday that he’d tried to warn this very same sign company that their software is easily penetrable by anyone with a computer and net connection and was told they were “not interested.” Even after the billboard was defaced, Tentler said the company still hadn’t secured its software.Probably best to just sick the lawyers on Dan. After all, this all must be his fault, somehow.

Airports around the world are slowly being upgraded to accommodate all the electronics we now travel with, but the process is slow. Finding an available outlet while waiting for a flight is often still a challenge, but with Bluelounge’s new Portiko in your carry-on, you’ll at least never end up sitting on the floor to ensure your power cords reach.
Really bad things happen. Though everyone should know this, here’s a lovely slow motion video reminder on what happens when you pour water onto an oil fire in an attempt to put it out: the fire gets even crazier because the water vaporizes into steam which expands causing it to spit out the oil which makes the flames even bigger.
A team at the French École Polytechnique Fédéral de Lausanne has developed and built a quadcopter with arms that unfold just before takeoff. The idea is that you can fold the device back up when you’re done with it, making it possible to store a bunch more of the quads in your backpack for instance.
The unfolding mechanism relies on the torque of the rotors spinning up to swing the arms into place. Once fully extended, a spring-loaded flap folds up, catches on some magnets, and forms an L-shaped structure that won’t re-fold without human intervention.
Under normal flying conditions, quads have a two left-handed propellers and two right-handed ones and the motors spin in opposite directions. In order to do the unfolding, two of the motors need to run essentially in reverse until the frame has clicked into place. They use a sensor (Hall effect?) to detect the arm locking, and then the rotors quickly switch back to their normal rotation before the quad hits the floor. In the video, they demonstrate that they’ve got this so well tuned that they can throw it up into the air to launch. Wow.
Everything’s still in prototype phase, and one of the next goals is “strengthening the arms so they can withstand crashes”, so don’t expect to see these in your local hobby store too soon. In the mean time, you’ll be able to see them in the flesh if you head up to the IEEE International Conference on Robotics and Automation in Seattle that started today and runs through Friday. If anyone goes, take more video and post in the comments?

You know all those GoPro videos you see on the Internet? You know the ones. Where crazy people skydive off planes and fly in wingsuits and snowboard and ride motorcycles and jump off cliffs and live Very Extreme Lives. All of that happens in the trailer for the remake of Point Break. Only they slapped a dark and gritty filter to make it “cinematic”.
