The new Enviro+ environmental monitoring sensors for Raspberry Pi

The alarming drop in our air quality is something that’s really important to understand. Devices like Enviro+ allow fine-grained, detailed datasets that let us see shifts in air quality through time and across different areas of cities. The more devices that contribute data, the better quality the dataset becomes.

My Dad, the Facebook Addict

Laughing Squid: Filmmaker Dylan LeVine hilariously documented his birthday candle-phobic father Vincent‘s obsession with Facebook and in particular, his overwhelming need to build an arsenal of memes, just in case. The elder LeVine shared how he researched and alphabetized every meme to ensure a full state of readiness should an argument ensue, until it became all he could think about. His family expressed repeated concern about the amount of time Vincent was spending online, but it was only after he was put on a three-day Facebook ban that he realized how much time and energy he was wasting in front of the computer.

Raspberry Pi retail store Cambridge

MagPi Magazine: The new store sells a wide range of Raspberry Pi boards, accessories, kits, and merchandise. More importantly, it has interactive product demonstrations and breakout areas for people to learn all about digital making with Raspberry Pi.

Gordon Hollingworth, Director of Software Engineering at Raspberry Pi: “The concept is about trying to get closer to a less connected demographic, people who aren’t involved with technology, and show them that coding isn’t an inexplicable dark science reserved only for a few. Instead show them that it is possible, with the right instructions and an inquisitive nature, to learn about computers and coding.”

The Raspberry Pi store has been gestating for “over six years,” says Gordon. But each year Gordon and Eben Upton, Raspberry Pi CEO and co-founder, “decided against it.”

Things changed when Maplin closed all its stores in 2018. “With the demise of Maplin, we decided there was the possibility of recruiting just the right person to launch the store for us.”

How iFixit Became the World’s Best iPhone Teardown Team

Motherboard: Every year there’s a race to become the first to tear down the phone, with teams from around the world flying to Australia—where it’s first released—to compete to be the first to look inside the world’s most coveted new phone. Motherboard embedded with iFixit, a California-based company whose primary mission is to make it easier for the average person to disassemble and repair their electronics, for its iPhone X teardown.

We went inside iFixit’s office, the “headquarters of the global repair movement, which features a tool laboratory and a parts library with thousands of electronics parts and disassembly tools. Then we went to Sydney, Australia, as iFixit tried to become the first team to tear down the iPhone X.

ZeroPhone

Hackaday blog: There are several open source phones out there these days, but all of them have a downside. Hard to obtain parts, hard to solder, or difficult programming systems abound. [Arsenijs] is looking to change all that with ZeroPhone. ZeroPhone is based upon the popular Raspberry Pi Zero. The $5 price tag of the CPU module means that you can build this entire phone for around $50 USD.

Features:

  • Raspberry Pi Zero in a PCB sandwich
  • No proprietary connectors, hard-to-get parts or chips that are tricky to solder
  • All the specifications for making this phone yourself will be available
  • Python as the main language for developing apps (aiming to add other languages later)
  • UI toolkit making development quicker and easier
  • Numeric keypad, 1.3" 128×64 monochrome OLED screen (with screen header supporting other types of screens)
  • 2G modem for phone functions, can be replaced with a 3G modem
  • WiFi (using an ESP8266), HDMI and audio outputs, a free USB host port
  • GPIO expansion headers for customization
  • RGB LED and vibromotor – for notifications
  • Tons of Pi Zero-related hacks that were discovered along the way, that I'll share with you as the project goes =)

Portraits of Imaginary People

A work in progress by Mike Tyka:

For a while now I’ve been experimenting with ways to use generative neural nets to make portraits.

Adding a third stage allows upressing up to 4k. However I dont have any actual training data at that resolution, meaning the network only learns to generally predict smooth edges etc, It can’t know the details of what skin pores or eyelashes look like. A super-highres database of faces would be needed here. Still for purposes of printing it’s nicer to create some interesting looking artifacts at this resolution, rather than bilinear interpolation of just pixelation.

Anyways, the goal is to make these into printable physical-world art pieces but I found in practice the resolution and detail has to be pretty high or it just doesn’t look nice printed. Like I said, it’s all work in flux and progress, more soon.

DermalAbyss: Colour changing tattoos that monitor your health

DermalAbyss: Possibilities of Biosensors as a Tattooed Interface

MIT Media Lab researcher Katia Vega: The Dermal Abyss presents a novel approach to biointerfaces in which the body surface is rendered an interactive display. Traditional tattoo inks were replaced with biosensors whose colors change in response to variations in the interstitial fluid. It blends advances in biotechnology with traditional methods in tattoo artistry.

We developed four biosensors, reacting to three biochemical information in body fluid and changes colors: The pH sensor changes between purple and pink, the glucose sensor shifts between blue and brown; the sodium and a second pH sensor fluoresce at a higher intensity under UV light.

Researchers at MIT Media Lab and Harvard Medical School teamed up to create tattoo ink that reacts to your body’s chemistry.

DermalAbyss

Co.Design: Researchers are getting closer to turning the skin into an interface, while designers imagine what these interfaces might look like. Do they come in the form of a tattoo, like Vega suggests, or a temporary tattoo that doubles as a circuit? Do they act like a second skin? Will we use them to control our devices, or to better understand our bodies? Either way, there’s a whole lot more to explore on the surface of our skin.

Crypto is hard: The secret cryptographic features of Barbie typewriters

The Barbie Typewriters are low-cost electronic typewriters developed as a children’s toy by Mehano in Slovenia (formerly Yugoslavia) and sold worldwide by Mattel.

Crypto Museum: Apart from a range of typesetting features, such as letter-spacing and underline, this children’s toy was capable of encoding and decoding secret messages, using one of 4 built-in cipher modes. These modes were activated by entering a special key sequence on the keyboard, and was explained only in the original documentation.

E-115 interior

When the E-115 was adopted by Mattel as an addition to the Barbie™ product line, it was aimed mainly at girls with a minimum age of 5 years. For this reason the product was given a pink-and-purple case and the Barbie logo and image were printed on the body. As it was probably thought that secret writing would not appeal to girls, the coding/decoding facilities were omitted from the manual. Nevertheless, these facilities can still be accessed if you know how to activate them.

SLO: 3D Printed Camera

SLO: 3D Printed Camera

Amos Dudley made made his own 3D printed camera, with lens.
He has even made the design files available for download so you can print your own.

SLO is a single lens objective. SLO is the mechanical shutter. SLO is the speed of good design, and the feeling of capturing life with a camera you made yourself.

A 3D printed camera body could look like anything, but I decided to optimize the design for printing speed and material usage. Most of the larger parts are designed without overhangs in one orientation, so they can be printed without supports, straight off the build platform. Separating the body into modules let me prototype each component individually. The shutter and lens are modules, and can be swapped out for different designs without reprinting the entire camera.

Creating a lens with a 3D printer is a challenge – your typical FDM printer won’t cut it here. […] The result was mixed- the lenses looked transparent, but weren’t optically sharp. Surface reflections were still blurry, which is a sign that a surface still has microscopic grooves that scatter light.

There’s no adjustment for shutter speed, except for the speed the button is pressed by your finger.

35mm is the most common film standard, and the natural choice for the SLO. It’s also the only film size that’s still relatively easy to get developed at a reasonable price. The choice of a film size informs many aspects of a camera’s design and function.

HP Pavilion Wave - front

HP Pavilion Wave

I really like the look of this new HP desktop. The Amazon Echo-esque form factor makes a lot of sense — if the voice assistant is the way of the future, the PC should absolutely be a speaker. And this has a B&O speaker, so it should be pretty decent too.

  • HP: HP’s newest desktops: Not your father’s PCThe small, triangular shaped HP Pavilion Wave – about 15 percent the size of a traditional tower – has a distinctive design that was formed by arranging the internal components into a layout that would be optimal for the most demanding computing tasks. On one side is the motherboard, including the processor, discrete graphics card and SSD, while a second side holds the hard drive. The third side contains the thermals – heat pipes that extract heat from the motherboard and graphics card, push it through copper pipes, across cooling fins and out the machine’s top.
  • Windows Blog: HP announces new Pavilion Wave and Elite Slice with Windows 10For customers who want a PC that can fit into small places, the new offering is a beautiful and compact design with the power of a full-sized desktop, running on Windows 10. The dual microphones enable voice integration with your digital personal assistant, Cortana.

  • The Verge: HP’s new PC looks like a speakerWhile the Wave isn’t a speaker, HP is still advertising its prowess as one. The computer has a large central speaker, which has its sound sent out in all directions by blasting against the sloped top cover of the PC. It’s a neat trick — and, during a brief demo in a small space, it did appear to get pretty loud — but it’s probably not a replacement for a dedicated speaker.

US government framework for handling cyberattacks

The Verge: The White House now has a color-coded scale for cybersecurity threats

The Presidential Policy Directive on United States Cyber Incident Coordination builds on the action plan that Obama laid out earlier this year, and it’s intended to create a clear standard of when and how government agencies will handle incidents. It also comes with a new threat level scale, assigning specific colors and response levels to the danger of a hack.

Cyber Incident Severity Schema

The cyberattack severity scale is somewhat vague, but it’s supposed to make sure that the agencies involved in cybersecurity — the Department of Justice, Department of Homeland Security, and Office of the Director of National Intelligence — respond to threats with the same level of urgency and investment.

Conceptual rendering of a “battery case” style introspection engine, piggybacked on an iPhone6.
Shape of things to come

The Introspection Engine

NSA whistleblower Edward Snowden has been working with hardware hacker Andrew “bunnie” Huang to develop a way for smartphone users to monitor whether their devices are making any potentially compromising radio transmissions.

“Trusting a phone that has been hacked to go into airplane mode is like trusting a drunk person to judge if they are sober enough to drive.”

The Intercept: Since a smartphone can essentially be made to lie about that state of its radios, the goal of Snowden and Huang’s research, according to their post, is to “provide field-ready tools that enable a reporter to observe and investigate the status of the phone’s radios directly and independently of the phone’s native hardware.” In other words, they want to build an entirely separate tiny computer that users can attach to a smartphone to alert them if it’s being dishonest about its radio emissions.

Snowden and Haung are calling this device an “introspection engine” because it will inspect the inner-workings of the phone. The device will be contained inside a battery case, looking similar to a smartphone with an extra bulky battery, except with its own screen to update the user on the status of the radios. Plans are for the device to be able to sound an audible alarm and possibly also to come equipped with a “kill switch” that can shut off power to the phone if any radio signals are detected. “The core principle is simple,” they wrote in the blog post. “If the reporter expects radios to be off, alert the user when they are turned on.”

Against the Law: Countering Lawful Abuses of Digital Surveillance, paper by Andrew ‘bunnie’ Huang and Edward Snowden:

Our introspection engine is designed with the following goals in mind:

  1. Completely open source and user-inspectable (“You don’t have to trust us”)
  2. Introspection operations are performed by an execution domain completely separated from the phone’s CPU (“don’t rely on those with impaired judgment to fairly judge their state”)
  3. Proper operation of introspection system can be field-verified (guard against “evil maid” attacks and hardware failures)
  4. Difficult to trigger a false positive (users ignore or disable security alerts when there are too many positives)
  5. Difficult to induce a false negative, even with signed firmware updates (“don’t trust the system vendor” – state-level adversaries with full cooperation of system vendors should not be able to craft signed firmware updates that spoof or bypass the introspection engine)
  6. As much as possible, the introspection system should be passive and difficult to detect by the phone’s operating system (prevent black-listing/targeting of users based on introspection engine signatures)
  7. Simple, intuitive user interface requiring no specialized knowledge to interpret or operate (avoid user error leading to false negatives; “journalists shouldn’t have to be cryptographers to be safe”)
  8. Final solution should be usable on a daily basis, with minimal impact on workflow (avoid forcing field reporters into the choice between their personal security and being an effective journalist)

Lessons about language from a Turkish typewriter

What I learned about languages just by looking at a Turkish typewriter, by Marcin Wichary, Design lead & typographer at Medium.

I don’t speak Turkish, and can’t read it either. I have never been to Turkey. I honestly don’t even know that much about Turkey. Why did I ask for a Turkish typewriter, then? Because it has one of the most fascinating keyboard layouts ever.

Some highlights:

  1. We’re not beholden to Q·W·E·R·T·YThe new layout had nothing in common with Q·W·E·R·T·Y. It was ergonomically superior, and measured to be up to twice as fast in typing; Turkey went on to break dozens of world records in typewriting championships before the end of century.
  2. Accented characters aren’t always second-class citizensTo me, this keyboard says “we’re proud of our language and we will treat it with respect.”
  3. Each language has a crazy secret…in Turkish, i gets capitalized to… İ, its tittle still there. But I exists also! And its lowercase form is, you guessed it… ı. Dotted i and dotless ı coexist in perfect harmony, and both have separate keys on the keyboard.
  4. Some of those other languages need to be accommodated alsoLook at the Turkish keyboard. There are three letters, w, x, and q, in a somewhat unusual location: right next to the digits in the top row.
  5. Punctuation is the first to go when sacrifices need to be madeSince backspacing was often physically difficult — welcome to the mechanical world — typewriters invented a certain power user shortcut. To type two characters in one space you would hold the spacebar, press as many characters as needed, and then release the spacebar to move to the next position.

Movie written by algorithm turns out to be hilarious and intense: Ars is excited to be hosting this online debut of Sunspring, a short science fiction film that’s not entirely what it seems.

Sunspring screenplay sample

Benjamin is an LSTM recurrent neural network, a type of AI that is often used for text recognition. To train Benjamin, [researcher, Ross] Goodwin fed the AI with a corpus of dozens of sci-fi screenplays he found online—mostly movies from the 1980s and 90s.

As the cast gathered around a tiny printer, Benjamin spat out the screenplay, complete with almost impossible stage directions like “He is standing in the stars and sitting on the floor.” Then Sharp [the director] randomly assigned roles to the actors in the room. “As soon as we had a read-through, everyone around the table was laughing their heads off with delight,” Sharp told Ars.

Sunspring

For Sharp, the most interesting part of the Benjamin experiment has been learning about patterns in science fiction storytelling. Benjamin’s writing sounds original, even kooky, but it’s still based on patterns he’s discovered in what humans write. Sharp likes to call the results the “average version” of everything the AI looked at. Certain patterns kept coming up again and again. “There’s an interesting recurring pattern in Sunspring where characters say, ‘No I don’t know what that is. I’m not sure,'” said Goodwin. “They’re questioning the environment, questioning what’s in front of them. There’s a pattern in sci-fi movies of characters trying to understand the environment.”
