Rovers To The Rescue: Robot Missions Tackles Trash

July 18, 2017 by 15 Comments

Everyone knows plastic trash is a problem with junk filling up landfills and scattering beaches. It’s worse because rather than dissolving completely, plastic breaks down into smaller chunks of plastic, small enough to be ingested by birds and fish, loading them up with indigestible gutfill. Natural disasters compound the trash problem; debris from Japan’s 2011 tsunami washed ashore on Vancouver Island in the months that followed.

Erin Kennedy was walking along Toronto Island beach and noticed the line of plastic trash that extended as far as the eye could see. As an open source robot builder, her first inclination was to use robots to clean up the mess. A large number of small robots following automated routines might be able to clear a beach faster and more efficiently than a person walking around with a stick and a trash bag.

Erin founded Robot Missions to explore this possibility, with the goal of uniting open-source “makers” — along with their knowledge of technology — with environmentalists who have a clearer understanding of what needs to be done to protect the Earth. It was a finalist in the Citizen Science category for the 2016 Hackaday Prize, and would fit very nicely in this year’s Wheels, Wings, and Walkers challenge which closes entries in a week.

Join me after the break for a look at where Robot Missions came from, and what Erin has in store for the future of the program.

Badge From Diamond Age Comes To DEF CON

July 14, 2017 by 12 Comments

We’re huge fans of [Neal Stephenson’s] work and are usually looking to assign some of his vision to the gear that pops up in the real world. But there’s no stretching or squinting necessary with this one. [Kerry Scharfglass] has built a functioning Drummer’s Badge from the foundational Sci-Fi novel The Diamond Age.

The badge is called Sympetrum, which is a genus of dragonfly. In explaining what the badge is and does, [Kerry] instructs you to go and read the book first and we couldn’t agree more. This isn’t recommended reading; if you’re a geek you need to read this book.

The dragonfly badges are from a portion of the book that gets pretty weird, but the gist is that rod-logic (machines build from microscopic carbon nanotubes) is so pervasive that at all times you’re covered in mites that are actually machines. At a party, one of the characters notices everyone is wearing dragonfly pins that begin to pulse with the music and synchronize with each other. They’re actually indicators of what the mites within the wearers’ bodies are doing — synchronizing people with other people.

This badge is a working recreation of that, presumably without the billions of mites controlling people (but who knows, it is DEF CON). At the center of the badge is an STM32 driving ten APA102 modules. Interactivity is based on IR signaling. The badge will cycle random color animations when alone. But each badge also projects clock sync and metadata over infrared, so put some of them in the same room and they’ll tend to synchronize.

Simple, beautiful, and a great geeky backstory. This example of Badgelife proves that hardware badges don’t need to be packed with features, or have a huge BOM cost. If done well, you can do an awful lot with just a little hardware and strong dose of inspiration. It also makes hand-assembly a lot more approachable, which is what you can see in the images above. Thanks [Kerry] for giving us an early look at this badge, can’t wait to see them at the CON.

We’ll be looking for this and all other #Badgelife offerings at DEF CON 25. Join us for a Hackaday meetup on Sunday morning as we once again do Breakfast at DEF CON

Hackaday Superconference: Tickets And Proposals

July 10, 2017 by 21 Comments

We’re thrilled to announce Supercon tickets are now available. The 2017 Hackaday Superconference is November 11th and 12th in Pasadena, California.

This is the ultimate hardware conference. Hackers, designers, and engineers from all over the world converge — from the greenest beginners to those who have made history with their designs. This is the Hackaday community, and the Supercon is your chance to experience all things involved in hardware creation for one great weekend. There will be unparalleled talks and workshops, but the experience of Supercon transcends the organized event. We call it a conference but it’s truly a hacker village.

Call for Proposals

Want to present a talk (or a workshop) at this year’s Supercon? Great, please submit your proposal using this form.

The number one question we get about CFP is “I’m excited about X, should I submit a proposal?” The answer is yes. Don’t self-eliminate — if you have an idea for a talk we want to hear from you. Supercon is a flat conference, your proposal will be judged on the idea and how you plan to present it, not on how many other amazing speaking slots you’ve secured.

To help get your mind moving about topics, we suggest that you consider this list of themes your talk might fit into: Engineering Heroics, Prototyping, Research, Product Development, Full-Stack Fabrication, and of course Wildcard.

Tickets! Get Your Tickets Here!

Are you a true believer? We’ve just opened up the Call for Proposal today, so we can’t tell you who’s speaking or what workshops will take place. However, we suspect there are many of you ready to take the plunge right now. Those first 96 true believers get an incredibly low ticket price of $128. This covers admission for both days of the con, admission to the Hackaday Prize party on Saturday night and food on both days.

This is the third year we’ve hosted the Hackaday Superconference. You can check out all of the talk videos from last year, there’s a slew of articles on the event, and of course it was really fun seeing the geeky and unique shirts on exhibit throughout.

Get your ticket and book your travel. We look forward to hanging out with a huge chunk of the Hackaday community at Supercon!

This Way To The Ingress: Keeping Stuff Dry And Clean With IP And NEMA

June 30, 2017 by 26 Comments

When designing a piece of hardware that has even the faintest chance of being exposed to the elements, it’s best to repeat this mantra: water finds a way. No matter how much you try to shield a project from rain, splashing, or even just humid air, if you haven’t taken precautions to seal your enclosure, I’ll bet you find evidence of water when you open it up. Water always wins, and while that might not be a death knell for your project, it’s probably not going to help. And water isn’t the only problem that outdoor or rough-service installations face. Particle intrusion can be a real killer too, especially in an environment where dust can be conductive.

There’s plenty you can do to prevent uninvited liquid or particulate guests to your outdoor party, but it tends to be easier to prevent the problem at design time than to fix it after the hardware is fielded. So to help you with your design, here’s a quick rundown of some standards for protection of enclosures from unwanted ingress.

The Arduino Foundation: What’s Up?

June 19, 2017 by 65 Comments

The Arduino Wars officially ended last October, and the new Arduino-manufacturing company was registered in January 2017.  At the time, we were promised an Arduino Foundation that would care for the open-source IDE and code infrastructure in an open and community-serving manner, but we don’t have one yet. Is it conspiracy? Or foul play? Our advice: don’t fret. These things take time.

But on the other hand, the Arduino community wants to know what’s going on, and there’s apparently some real confusion out there about the state of play in Arduino-land, so we interviewed the principals, Massimo Banzi and Federico Musto, and asked them for a progress report.

The short version is that there are still two “Arduinos”: Arduino AG, a for-profit corporation, and the soon-to-be Arduino Foundation, a non-profit in charge of guiding and funding software and IDE development. The former was incorporated in January 2017, and the latter is still in progress but looks likely to incorporate before the summer is over.

Banzi, who is a shareholder of Arduino AG, is going to be the president of the Foundation, and Musto, AG’s CEO, is going to be on the executive board and both principals told us similar visions of incredible transparency and community-driven development. Banzi is, in fact, looking to get a draft version of the Foundation’s charter early, for comment by the community, before it gets chiseled in stone.

It’s far too early to tell just how independent the Foundation is going to be, or should be, of the company that sells the boards under the same name. Setting up the Foundation correctly is extremely important for the future of Arduino, and Banzi said to us in an interview that he wouldn’t take on the job of president unless it is done right. What the Arduino community doesn’t need right now is a Foundation fork.  Instead, they need our help, encouragement, and participation once the Foundation is established. Things look like they’re on track.

Intel Discontinues Joule, Galileo, And Edison Product Lines

June 19, 2017 by 195 Comments

Sometimes the end of a product’s production run is surrounded by publicity, a mix of a party atmosphere celebrating its impact either good or bad, and perhaps a tinge of regret at its passing. Think of the last rear-engined Volkswagens rolling off their South American production lines for an example.

Then again, there are the products that die with a whimper, their passing marked only by a barely visible press release in an obscure corner of the Internet. Such as this week’s discontinuances from Intel, in a series of PDFs lodged on a document management server announcing the end of their Galileo (PDF), Joule (PDF), and Edison (PDF) lines. The documents in turn set out a timetable for each of the boards, for now they are still available but the last will have shipped by the end of 2017.

It’s important to remember that this does not mark the end of the semiconductor giant’s forray into the world of IoT development boards, there is no announcement of the demise of their Curie chip, as found in the Arduino 101. But it does mark an ignominious end to their efforts over the past few years in bringing the full power of their x86 platforms to this particular market, the Curie is an extremely limited device in comparison to those being discontinued.

Will the departure of these products affect our community, other than those who have already invested in them? It’s true to say that they haven’t made the impression Intel might have hoped, over the years only a sprinkling of projects featuring them have come our way compared to the flood featuring an Arduino or a Raspberry Pi. They do seem to have found a niche though where there is a necessity for raw computing power rather than a simple microcontroller, so perhaps some of the legion of similarly powerful ARM boards will plug that gap.

So where did Intel get it wrong, how did what were on the face of it such promising products fizzle out in such a disappointing manner? Was the software support not up to scratch, were they too difficult to code for, or were they simply not competitively priced in a world of dirt-cheap boards from China? As always, the comments are open.

Amazon Echo Show

June 15, 2017 by 22 Comments

Back in May, Amazon announced the Echo Show, its new version of Alexa with a 7 inch touchscreen. The Echo Show is an interesting device, but will the great unwashed masses pony up $229 to buy the show? That’s $50 more than the original Echo, or $180 more than the Echo Dot. With 5.2 million units sold in 2016, Echo has been a resounding success. This has been in part due to Amazon’s open approach to the API. Anyone can build an Alexa compatible device using a Raspberry Pi. Google has (finally) followed suit with their Home device.

It’s not just the hardware that is accessible. Skills Kit, the programmer interface for extending Echo’s functionality, is also open. At CES this year, Alexa was the belle of the ball. Third party devices are being introduced from all corners, all of them connecting to Amazon’s cloud and responding to the “Alexa” keyword.

The Echo Show takes the family in a new direction. Adding a touch screen gives the user a window on the the world not available with voice interactions. Echo Show also includes a camera, which opens up a whole new set of privacy and security questions. Amazon touts it as a device for viewing security cameras, watching YouTube videos, and making video calls. This puts Echo Show dangerously close to the internet appliance category, essentially a barren wasteland littered with the corpses of previous devices. Does anyone remember when Palm tried this with the 3Com Ergo Audrey? How about the i-Opener? Will Alexa persevere and succeed where others have failed? A lot of it will depend on the third party developers, and how Amazon treats them.
