London Gatwick Airport Closes Runway In Alleged Drone Strike

July 4, 2017 by Jenny List 118 Comments

London is one of those cities with an identity problem when it comes to airports. There is no one London airport, instead a group of airports serve the city at various distances from it. London Gatwick is the second largest of these, and sits with its single runway in the Sussex countryside about 30 miles south of the city.

If you follow British news sources, you may have heard a little about Gatwick in the last couple of days. Its runway was closed for two short periods and a selection of flights were diverted, because of what is being reported as a drone sighting. This is an extremely serious matter, responsible multirotor owners will be painfully aware of the distance and altitude regulations surrounding flights near airports.

If you are familiar with the way that drone stories are reported by the mass media, you will probably not need to click on the link above to the BBC reporting to find out its tone. There is significant concern within the multirotor community that it presents a very one-sided view, and takes at face value the assertion that the sighting was a drone, when in fact there is no proof at all of that being the case. For those of us who have seen many such stories come and go it is difficult not to agree with the drone pilots, there is at best some lazy reporting in the air, and at worst some outright journalistic irresponsibility.

As Hackaday readers, you are used to writers with an in-depth knowledge of the subjects upon which they write. We don’t know all possible facets of technology and we occasionally get things wrong, but we all have very strong backgrounds in the tech, hacker, and maker industries and communities we write about. We have engineering education, we’ve worked in a wide variety of technology industries, we build our own stuff for fun, and we’ve founded and run hackspaces.

By comparison the journalists whose work you will read in the mainstream media are generalists. They will have a specific educational background and a particular set of interests, but in their work they cover whatever stories tumble off the endless conveyor belt of events. Thus when a drone story appears, they find themselves out of their normal comfort zone of politics or local news, and can not rely on their experience to inform their coverage of it. The responsible journalistic approach is to do a little research and ask the pertinent questions asking for concrete proof of drone involvement. We’re still waiting for that to happen in these allege drone encounters.

Multirotor building and flying is a significant feature of our community, and anything that brings the attention of law enforcement to the kind of work we do should be a worry to us all. Multirotors are not the only things covered by Hackaday that could be misrepresented in the same way. We’ve visited this topic before, take a look at our analysis of a series of air proximity reports blamed on drones. Some of them, you couldn’t make up.

New Ransomware Crippling Chernobyl Sensors

June 28, 2017 by Jack Laidlaw 87 Comments

[The BBC] reports Companies all over the world are reporting a new ransomware variant of WannaCry. this time it has taken out sensors monitoring the Chernobyl nuclear disaster site.

We have all heard of the growing problem of ransomware and how Windows XP systems seem especially susceptible to WannaCry and it’s variants which were originally zero day vulnerabilities stored up by the NSA then leaked by WikiLeaks. Microsoft did release a patch. It’s been everywhere in the media but it still seems that some people didn’t get the memo.

Ukrainian state power plants and Kiev’s main airport, among others, have been affected. Probably most interesting and scary of all is that Chernobyl monitoring stations have been taken out, and monitors have to take radiation levels manually for the moment.

It seems that most reports are coming from old Soviet Bloc states (Ukraine, Russia, and Poland), which raises the question of where the attacker is based. Kaspersky Lab is reporting that it’s believed the ransomware was a “new malware that has not been seen before” with a close resemblance to Petya. So as a result, the firm has dubbed it NotPetya.

NotPetya is spreading rapidly affecting companies all over the world with no signs of slowing just yet. Will we see an end to WannaCry variants any time soon.

[Update Thanks to [getrekt] , It now seems that this is fake ransomware which just destroys your data whether you pay or not.]

CastAR Shuts Doors

June 27, 2017 by Brian Benchoff 100 Comments

Polygon reports CastAR is no more.

CastAR is the brainchild of renaissance woman [Jeri Ellsworth], who was hired by Valve to work on what would eventually become SteamVR. Valve let [Jeri] go, but allowed her to take her invention with her. [Jeri] founded a new company, Technical Illusions, with [Rick Johnson] and over the past few years the CastAR has appeared everywhere from Maker Faires to venues better focused towards innovative technologies.

In 2013, Technical Illusions got its start with a hugely successful Kickstarter, netting just north of one million dollars. This success drew the attention of investors and eventually led to a funding round of $15 million. With this success, Technical Illusions decided to refund the backers of its Kickstarter.

We’ve taken a look a CastAR in the past, and it’s something you can only experience first-hand. Unlike the Oculus, Google Cardboard, or any of the other VR plays companies are coming out with, CastAR is an augmented reality system that puts computer-generated objects in a real, physical setting. Any comparison between CastAR and a VR system is incomplete; these are entirely different systems with entirely different use cases. Think of it as the ultimate table top game, or the coolest D&D game you could possibly imagine.

Flash A Light Bulb, Win A Prize

June 25, 2017 by Dan Maloney 47 Comments

How many geeks does it take to flash a lightbulb? Judging from the list of entries in the 2017 Flashing Light Prize, so far only seven. But we suspect Hackaday readers can add to that total.

The goal is almost as simple as possible: build something that can flash an incandescent light bulb for at least five minutes. The system actually has to power the bulb’s filament, so no mechanical shutters are allowed. Other than that, the sky is the limit — any voltage, any wattage, any frequency and duty cycle, and any circuit. Some of the obvious circuits, like an RC network on a relay, have been tried. But we assume there will be points for style, in which case this sculptural cascading relay flasher might have a chance. Rube Goldberg mechanical approaches are encouraged, as in this motor, thread, stick and switch contraption. But our fave thus far is the 1000-watt bulb with solar cell feedback by Hackaday regular [mikeselectricstuff].

Get your entry in before August 1st and you’ll be on your way to glory and riches — if your definition of rich is the £200 prize. What the heck, your chances are great right now, and it’s enough for a few pints with your mates. Just don’t let it distract you from working on your 2017 Hackaday Prize entry — we’re currently in the “Wheels, Wings, and Walkers” phase, so maybe there’ll be a little crossover that you can leverage for your flasher.

A Goldmine Of Radio Shack Goodies Is Up For Auction

June 24, 2017 by Jenny List 49 Comments

Where did you buy the parts for your first electronic project? That’s a question likely to prompt a misty-eyed orgy of reminiscences from many Hackaday readers, if ever we have heard one. The chances are that if you are from North America or substantial parts of the English-speaking world, you bought them from a store that was part of the Radio Shack empire. These modestly sized stores in your local mall or shopping centre carried a unique mix of consumer electronics, CB radio, computers, and electronic components, and particularly in the days before the World Wide Web were one of very few places in which an experimenter could buy such parts over the counter.

Sadly for fans of retail electronic component shopping, the company behind the Radio Shack stores faltered in the face of its new online competition over later years of the last decade, finally reaching bankruptcy in 2015. Gone are all but a few independently owned stores, and the brand survives as an online electronics retailer.

The glory days of Radio Shack may be long gone, but its remaining parts are still capable of turning up a few surprises. As part of the company’s archives they had retained a huge trove of Radio Shack products and memorabilia, and these have been put up for sale in an online auction.

There is such a range if items for sale that if you are like us you will probably find yourself browsing the listings for quite a while. Some of it is the paraphernalia of a corporate head-office, such as framed artwork, corporate logos, or strangely, portraits of [George W. Bush], but the bulk of the collection will be of more interest. There are catalogues galore from much of the company’s history, items from many of its promotions over the years including its ventures into sporting sponsorship, and numerous examples of Radio Shack products. You will find most of the computers, including a significant number of TRS-80s and accessories, tube-based radios and equipment from the 1950s, as well as cardboard boxes stuffed with more recent Realistic-branded items. There are even a few retail technology dead ends to be found, such as a box of :CueCat barcode readers that they evidently couldn’t give away back in the dotcom boom.

If you are interested in any of the Radio Shack lots, you have until the 3rd of July to snap up your personal piece of retail electronic history. Meanwhile if you are interested in the events that led to this moment, you can read our coverage of the retail chain’s demise.

Thanks [Mark Scott] for the tip.

Heathkit’s New RF Meter: Who Is It For?

June 23, 2017 by Al Williams 25 Comments

Electronic hackers and ham radio operators of a certain age have a soft spot for the Heathkit brand. Maybe that’s why we had a rush of nostalgia when we saw the Heathkit site had a new product. You may recall that Heathkit had gone the way of the dodo until a few years ago when the brand started to resurface. Their latest kit is a precision RF meter which is available on preorder.

Before there were websites and hacker spaces and all the modern push to “do it yourself,” Heathkit was teaching people electronics through kit building. Sure, they were known for ham radio and test equipment, but many people built stereos (hi-fi), TVs, radio control gear, computers, and even robots. All with manuals that are hard to imagine if you haven’t seen one. They were world-class.

EV3DEV Lego Linux Updated

June 23, 2017 by Al Williams 8 Comments

The ev3dev Linux distribution got an update this month. The distribution targets the Lego EV3 which is a CPU Lego provides to drive their Mindstorm robots. The new release includes the most recent kernel and updates from Debian 8.8. It also contains tools needed for some Wi-Fi dongles and other updates.

If you haven’t seen ev3dev before, it is quite simply Linux that boots on the EV3 hardware using an SD card. You don’t have to reflash the computer and if you want to return to stock, just take out the SD card. You can also use ev3dev on a Raspberry Pi or BeagleBone, if you like. There’s a driver framework included for handling sensors, motors, and other items using the file system.
