Woah, the cyber-future is here! Flexible E-Ink has been demo’d at high tech events for years but now you can actually get your paws on it. This display is true E-Ink / E-Paper, once an image is displayed it will stay even once you remove all power. The image is also high contrast and very daylight readable. It really does look just like printed paper!
This flexible display sports a 2.9″ monochrome (black and white) display. It has 296×128 black ink pixels on a white-ish background. The monochrome displays also take a lot less time to update, only a couple seconds instead of 15 seconds.
Please note: this display is flexible but that doesn’t mean you can constantly flex it.
Using our CircuitPython or Arduino libraries, you can create a ‘frame buffer’ with what pixels you want to have activated and then write that out to the display. Most simple breakouts leave it at that. But if you do the math, 296 x 128 pixels = 4.7 KBytes. Which won’t fit into many microcontroller memories. Heck, even if you do have 32KB of RAM, why waste 5KB?
Note: This is just the display. You’ll want your own eInk Breakout Friend too!

“National 4‑H Council announced a new $6 million collaboration with Google to bring computer science (CS) education to underserved youth across the country. The collaboration will expand the 4‑H Computer Science (CS) Career Pathway to reach more than one million youth over the next three years, with a focus on rural youth and populations that have traditionally had limited access to CS education.”
“RYOR, Okla. (AP) — Google has announced a $600 million expansion project at a data center in Pryor, Oklahoma, and a $6 million grant for computer science education for students in 4-H chapters in rural areas of 20 states. The announcement was made Thursday outside the data center. The expansion project is expected to add about 100 jobs to the more than 400 now employed at the center that opened in 2011. National 4-H Council President Jennifer Sirangelo said the grant through Google.org will focus on computer science training for an estimated 1 million children in rural areas that have limited access to computer science education. Google CEO Sundar Pichai said the grant will be used to teach coding and leadership skills to students.”
Google’s funding will expand 4-H’s Computer Science Career Pathway (PDF) to reach more than one million youth over the next three years.
We look forward to helping 4-H in the efforts and thank Google.org for an amazing grant to 4-H!

Festival season is upon us! And I just got a new bike. That means it’s time to take my old Trek mountain bike to the next level and turn it into a fancy, pretty, silly mermaid bike with blinky lights and lots of style, so I can stand out this summer while I’m getting where I need to go.
It’s already mid June, so I’m already feeling behind. I want to have this bike ready by late July at the very latest, which gives me a month to plan, paint, decorate, build, program, and stress-test. It’s definitely time to get started.
My focus is going to be on durability first and style second. I do not want to have to repair any LED strips while camping, but I’m going to put together a repair kit anyway just in case. But my mantra for the build is going to be all about robust-ness. I’ve made a light-up mermaid tail that swims underwater, so I’ll be using some of the same techniques to get this bike as break-proof as possible.
I’m creating a tutorial on the Adafruit learning system as I go. Follow along with the process as you start dreaming about your own ultimate Playa Bike!

What is turtle? For Python it is…
Turtle graphics is a popular way for introducing programming to kids. It was part of the original Logo programming language developed by Wally Feurzig and Seymour Papert in 1966.
Turtle graphics are often associated with the Logo programming language. Seymour Papert added support for turtle graphics to Logo in the late 1960s to support his version of the turtle robot, a simple robot controlled from the user’s workstation that is designed to carry out the drawing functions assigned to it using a small retractable pen set into or attached to the robot’s body. Turtle geometry works somewhat differently from (x,y) addressed Cartesian geometry, being primarily vector-based (i.e. relative direction and distance from a starting point) in comparison to coordinate-addressed systems such as PostScript. As a practical matter, the use of turtle geometry instead of a more traditional model mimics the actual movement logic of the turtle robot. The turtle is traditionally and most often represented pictorially either as a triangle or a turtle icon (though it can be represented by any icon).
Today, the Python programming language’s standard library includes a Turtle graphics module. Like its Logo predecessor, the Python implementation of turtle allows programmers to control one or more turtles in a two-dimensional space. Since the standard Python syntax, control flow, and data structures can be used alongside the turtle module, turtle has become a popular way for programmers learning Python to familiarize themselves with the basics of the language.

War, natural disasters and climate change are destroying some of the world’s most precious cultural sites. Google is trying to help preserve these archaeological wonders by allowing users access to 3D images of these treasures through its site.
But the project is raising questions about Google’s motivations and about who should own the digital copyrights. Some critics call it a form of “digital colonialism.”
When it comes to archaeological treasures, the losses have been mounting. ISIS blew up parts of the ancient city of Palmyra in Syria and an earthquake hit Bagan, an ancient city in Myanmar, damaging dozens of temples, in 2016. In the past, all archaeologists and historians had for restoration and research were photos, drawings, remnants and intuition.
But that’s changing. Before the earthquake at Bagan, many of the temples on the site were scanned. One of them, Ananda ok Kyaung, stands out for Chance Coughenour, a manager at Google Arts & Culture. “This is a temple that has incredible murals, floor to ceiling across the inter-passageways and the inter-chamber of the temple,” he says.

If you mastered the local course, stop by the Nelson-Atkins Museum of Art to play golf with an artistic twist.
It could be said that the art of miniature golf design reached its pinnacle when some crafty individual decided to plop a windmill on a course, challenging players to sink a hole-in-one past its rotating blades. Over time windmills have become synonymous with the miniaturized sport, so leave it to a museum to shake up mini golf course design for the first time in years (insert golf clap here).
Taking inspiration from its vast collection of artworks, the Nelson-Atkins Museum of Art in Kansas City, Missouri, has created a nine-hole golf course that changes how we view not just mini golf, but also art. Appropriately titled “Art Course,” each hole reinterprets a piece of art in the museum’s permanent collection. And the best part: It’s completely interactive.

Purrfect prom pics of a furry friend! Everyone should get glamour-shots of their pets. Via My Modern Met:
When you’re a pet parent and have someone else taking care of your furry friend, the best you can hope for is that they feed them on time and clean up after them. But when actor and photographer Josell Mariano’s friend asked him to “babysit” her beloved feline Jade, Mariano surprised her with something a little extra. He used his Canon 6D camera and a strobe light to snap a series of striking portraits of the all-gray shorthair. Set against a dark gray background, Jade looks pawsitively distinguished—even when she’s making goofy faces.

Parallax has the hardware origin story that many dream of. Chip Gracey was selling self developed hardware at 15, bailed on college, and started his own company first building expansion cards for the Apple IIGS. Parallax hit the map with their BASIC Stamp microcontroller, which was one of the early and now most prevalent microcontrollers on the market, really before “maker” electronics were even a thing.
The Gracey brothers recently joined the MacroFab podcast recounting these early days, and talked a lot about the intricacies and challenges of manufacturing, especially with regards to integrated circuit development. It’s been 32 years since Parallax was founded, and they are on the cusp of launching their latest self developed chip as a part of their Propeller 2 board (coming later this year).
The Propeller 2 cost hundreds of thousands of dollars up front, and their last design change cost $82,000! The host, Parker Dillman, commented with a hyperbolic but enlightening bit of wisdom from his earlier hardware days:
You want 1 custom chip? It’s a $100,000 dollars. You want 100,000 custom chips? It’s $100,00 dollars.
The upfront cost is huge. There needs to be a ton of research and modeling done before production even begins. Designers of the latest cutting edge chips are looking at hundreds of millions in costs to just get their first manufacturing run going. This really narrows the field on who can design new chips. With the Propeller 2, Parallax is turning away from this, sticking to their roots of accessibility and less arcane functionality.
Listen to the whole show here, there is a lot to take away and with the Propeller 2 nearly at launch, there is a lot to look forward to.

HyperCard was a software application and development kit for Apple Macintosh and Apple IIGS computers. It was among the first successful hypermedia systems predating the World Wide Web. Could this model be resurrected to run on modern IoT handhelds?
HyperCard combines a flat-file database with a graphical, flexible, user-modifiable interface. HyperCard includes a built-in programming language called HyperTalk for manipulating data and the user interface.
This combination of features – a database with simple form layout, flexible support for graphics, and ease of programming – suits HyperCard for many different projects such as rapid application development of applications and databases, interactive applications with no database requirements, command and control systems, and many examples in the demoscene.
HyperCard was originally released in 1987 for $49.95 and was then included for free with all new Macs sold. It was withdrawn from sale in March 2004, having received its final update in 1998 upon the return of Steve Jobs to Apple. HyperCard runs in the Classic Environment, but was not ported to Mac OS X.
Below is an introduction to Apple’s Hypercard from 1987 for context.
With the advent of other software, HyperCard was no longer sold with Macs by the turn of the century. The software can run in computer emulators but that is an extra layer of software and hardly portable.
It would be a natural fit for bringing together the current breed of microcontrollers, like the Microchip SAMD51 and increasingly cheaper LCD displays to implement a hypercard-like program on hardware. Microsoft MakeCode Arcade is spawning a new generation of Internet of Things devices with a strong microcontroller coupled with an LCD screen. These devices run CircuitPython, a natural language for applications development, with strong graphical capabilities, access to storage like the Macs of old, and now Internet connectivity, if desired.
Adafruit Industries is leading the technology industry in hardware integration. Starting with their PyPortal IoT Screen, they’ve subsequently introduced the PyBadge series and the PyGamer series. These low cost, high performance devices would be a natural fit for hypercard-like software.
Keep an eye on the Adafruit Blog for additional details.
There are still learning materials available online for knowing how to use HyperCard. See this Adafruit Blog post for details.

A retrofit by cmot17 of a Logitech MX Master upgrades the battery and USB-C. The battery was upgraded from 500 mAh to 950 mAh. The USB micro B connector was carefully cut away and an Adafruit USB-C breakout board trimmed to fit in its place. Delicate work to ensure nothing vital was cut.
Since [cmot17] didn’t change the mouse’s original electronics, the newly upgraded Logitech MX Master won’t actually benefit from the faster charging offered by USB-C. If anything, it’s actually going to charge slower thanks to the beefier battery. But considering how infrequently it will need to be charged with the upgraded capacity (Logitech advertised 40 days with the original 500 mAh battery), we don’t think it will be a problem.

Lovely, educational activity from Scientific American.
Springtime is when nature appears to come back to life after winter. Trees grow leaves, grass gets green, and flowers sprout, displaying beautiful colors and sometimes spreading a delightful scent. But have you ever looked at a flower in more detail? What parts do flowers consist of? Are all flowers alike? In this activity you will find out by dissecting, or taking apart, a flower piece by piece. How many plant parts do you think you can identify?

Another dizzying video by Páraic Mc Gloughlin (previously) pairs shots of architecture and infrastructure with electronic music. Mc Gloughlin’s latest work is for the band Weval’s track “Someday,” and features the filmmaker’s signature fusion of geometric shapes found in historical domes, skyscraper facades, and farmland irrigation systems. The tightly edited video shows quickly-passing frames that shift in time with the music, visually quaking or smoothly transitioning depending on the percussive and melodic elements of the song. Macro shots of escalator stairs and grates are interspersed with far-away aerial views of landscapes and forests, for a fast-paced tour of the patterns around us, hidden in plain sight. You can see more from Mc Gloughlin on Vimeo and Instagram.

Wonderful story about how Dr. Chester Pierce helped build the world of Sesame Street, from Mother Jones.
Sesame Street is celebrating its 50th anniversary this year. The rush of stories and social posts about the iconic children’s TV show has inspired numerous stories about Muppets and cast members.
Few, however, noted the role of Dr. Chester Pierce, a psychiatrist and Harvard Medical School professor who was instrumental to the show’s early development and vision.
In 1969, Pierce signed up to be a senior adviser to Sesame Street creators Joan Ganz Cooney and Lloyd Morrisett. The founding president of the Black Psychiatrists of America, Pierce blamed television for furthering racist tropes, but also saw the medium as an opportunity to break those stereotypes, according to Undark Magazine.

In anticipation of the historic 50th year anniversary of the Stonewall Riots (the landmark black and brown-led 1969 rebellion that gave birth to the modern LGBT rights movement)—the Baldwin Hansberry Project will partner with the Schomburg Center for Research in Black Culture to host a special one day symposium entitled “After Stonewall: 50 Years of Black and Brown Resistance.”
The keynote event of this symposium will be a staged public intergenerational dialogue between leading black LGBT activists reflecting on the various “lessons” that Stonewall teach contemporary activists (i.e. the importance of letting Transwomen lead; the political effectiveness of disruptive direct action; and the power of multiracial organizing). During the symposium, we will launch the hashtag #BlackStonewall50 as a public awareness campaign that highlights the black and brown roots of Stonewall.

Regardless of how you feel about BigFoot or the Sasquatch, the FBI just released files on their investigation.
Byrne first wrote to the FBI in August of 1976, writing that his institute had been working for six years to uncover the truth, whatever that may be, about Bigfoot. Byrne had recently discovered a tissue sample containing fifteen hairs and some skin which he was unsuccessful in identifying. Working under the assumption that the FBI had previously examined purported Sasquatch hairs — information reported in the 1975 publication of the Washington Environmental Atlas — Byrne requested the FBI take a look at his sample. Byrne further clarified in his letter, “Please understand that our research here is serious. That this is a serious question that needs answering.”
On September 10th of the same year, Byrne received a response from Jay Cochran Jr., Assistant Director of the Scientific and Technical Services Division at the FBI. Cochran stated that the agency had received several inquiries as to the Bureau’s activities in examining evidence of Bigfoot, since the publication of the Washington Environmental Atlas, “However, we have been unable to locate any references to such examinations in our files.”

Building Iron Man
SEASON 1, EPISODE 1
Adam Savage teams up with a daredevil inventor to build an authentic Iron Man suit that flies and stops bullets just like Tony Stark’s.
Savage Builds is on Fridays at 10p E/P on the Discovery Channel (following the new Battlebots).
On to the review, is it worth watching? YES. Everyone is busy, the competition for 41 minutes in our lives is street brawl with no rules. If you like making things, how things are made, how they are “unmade” with explosives, this show has it all. The show premiered Friday night, however Limor and I watched it Sunday night since Friday to Sunday afternoon was electronics, coding, and prototyping. Our cable provider does on-demand now, so we were able to watch it any time, and skip (some of) the commercials. It’s also online. I feel this is important, it was not hard to watch this when we had the time.
Savage Builds to me seems like an evolution of Mythbusters: and then some… Mythbusters: tested something that may or may not be true, where Savage Builds celebrates the builder, the maker, the super-advance technologies that can make a Tony Stark functional Iron Man suit come to life, get shot (no damage), blown up, and fly.
What sparks any of us to decide to make something, or a kid who decides to take the life long journey of being an engineer? For some, it might be this show. Can we (humans, 2019) make something we see in the movies like an Iron Man suit? Yes, and wow – the build is as impressive as any special effects and CGI. The 3D printing of titanium, the flying, it’s all possible, just gotta have the skills which are obtainable with smarts, dedication, and working with other talented people.
If you are a young person now, watch this show, you can do this, you can make this, while it’s technically impressive, it’s not magic, or movie magic. It’s engineering. There has never been a better time to jump in. Imagine what you’ll be able to make in less than 10 years if this is possible now.
3D printing with titanium, about 250 parts! It must have taken MONTHS of print time.
Riveting titanium plates with Clecos. Handy tip!
Craig Brice, professor of mechanical engineering at Colorado School of Mines, helped Adam Savage design and build the suit.
Seeing the challenges of learning to fly with a Gravity Jet Suit in hours. Richard Browning of course makes it look easy.
It was also great to see Jen Schachter‘s work on the show builds as well.
Savage Builds is off to a perfect start, we’re looking forward to the rest of the episodes. Congrats Adam and team.

How It Works
The Oura ring tracks your blood volume pulse directly from the palmar arteries of the finger with infrared LED sensors. We deliberately designed Oura as a ring (rather than a watch) because the arterial pulse at the finger delivers a significantly more accurate reading than what can be collected from the wrist. From that data, Oura’s algorithms calculate your resting heart rate and heart rate variability (HRV).

“…Playdate, the most amazing and exciting product announcement, for me, since the original iPhone.” – John Gruber
I’ve read John’s site for years and probably still will, even with this comment to his 371,000 Twitter followers about Kevin’s open-source product, the Arduboy.
I suppose this is one way to get developers (or anyone) interested in Playdate since John is one of the first high-profile, super-vocal promoters of Playdate. Putting this post up here to see what type of game development community emerges from Playdate as it gets closer to shipping, and if it’s going to be welcoming or as the person who tweeted back said, “snooty.”
There’s enough room for all types of hardware in gaming, everyone plays games, just like everyone “makes” something.
We signed up for the Playdate SDK/dev stuff, we’ll be picking one up and trying to make games for it and maybe some hardware accessories too.
What is Arduboy?
Arduboy is a miniature game system the size of a credit card. Installed with a classic 8-bit game and can be reprogrammed from a library of open source games available online. Arduboy is open source so you can learn to code and create your own games.
Read more. It’s $49, shipping now, games are black and white, there are a lot of things that are like the Playdate, and if you’ve made games for the Arduboy, you might want to check out Playdate too.

From VH Home Insurance:
Originally intended chiefly for military operations, drones or Unmanned Aerial Vehicles (UAV) are increasingly being used for commercial, scientific, recreational, agricultural and other purposes. When it comes to usage in real estate and for home inspection, the ability of drones to capture spectacular aerial views through cameras attached to the device is what separates them from any other technology.
Welcome to drone day on the Adafruit blog. Every Monday we deliver the latest news, products and more from the Unmanned Aerial Vehicles (UAV), quadcopter and drone communities. Drones can be used for video & photography (dronies), civil applications, policing, farming, firefighting, military and non-military security work, such as surveillance of pipelines. Previous posts can be found via the #drone tag and our drone / UAV categories.

The TS80 is a chic and smart soldering iron powered by USB Type-C and QC3.0 standard input. Normally we’d scoff at trying to power a soldering iron off of USB, but thanks to the new USB C standard, the power plug that’s included is a 9V 2A so you get a reasonable ~20 Watts of power. So, this is the first USB iron we would feel comfortable stocking, it’s a nice iron, good enough for every-day use. We dig the slim pen iron (so comfortable to hold), adjustable temperature (oooh there’s a OLED screen!), durable grounding cord, and fast heat-up (about 22 seconds)!
Comes equipped with an OLED screen, so you can keep an eye on the temperature. With a built-in STM32 chip, it can control the rise and fall of tip temperature, and it features sleep, automatic power-off, and other modes. The code application layer is open source; you can develop firmware for the soldering iron. You can even customize the boot up screen with your own 96×16 pixel BMP image!
When you don’t need a full soldering ‘battle station’, this pen-type iron will work well, either on a bench-top or in a tool box. It can handle any task you throw at it, and the handy buttons set the temperature. Once the soldering is complete and the iron has cooled off, you can easily coil it up to keep your work space clean and tidy.
This soldering iron has an adjustable temperature range from 100ºC to 400ºC. For most lead-free soldering, try 400°C. For lead-based solder, 350°C will do. Adjust as necessary! It may not be as powerful or easy-to-use as the full stand-up Hakko, but it is a lot more portable. We also carry a soldering iron stand (and a deluxe model as well) in case you want to keep it from rolling around your desk.
The soldering tip is connected via a 3.5mm push-in plug, making replacing tips super easy. The tip it comes with is a nice general-purpose D25 screwdriver tip for all through-hole and larger-SMT work, it’s got plenty of metal behind it so it retains and transfers heat well. Note that the tip is not Hakko-compatible!
Kit also includes USB C power supply, the tiniest Allen wrench for attaching the optional grounding clip, and said grounding clip.

This is a screen for advanced hackers who like the look of the TFT screen we’ve put into the PyPortal, PiTFT Plus, and TFT breakout. This display has 320×240 pixels and is driven with the ILI9341 chipset. This is just the display module! No PCB is included! You can talk to this chip with SPI (4 or 3 wire), 8 bit parallel, or 16 bit parallel. It also can be put into “dot clock mode” for raw TTL signal in but we have never done this ourselves so there’s no example code for that.
We’re selling this module bare for those who want to integrate it into their own project. If this is your first time working with this TFT we suggest our breakout board which makes it easy to use SPI or 8-bit interfacing and also has mounting holes, level shifting, etc.. Otherwise you can pick up one of our 50-pin FPC breakouts and an 50-pin FPC connector and solder it up by hand. For the TFT command set, the data sheet is very complete, but we also have some Arduino code you can refer to here to get started.
A 50-pin, 0.5mm pitch, top-contact FPC connector is required to connect to this screen. You cannot solder this connector directly to a PCB – a matching connector is required, you can pick one up here.
The resistive touch screen is a classic ‘analog’ touch screen which requires either a micro controller with analog inputs OR the use of a touch screen controller, such as this one.

Via Fast Company:
That’s the idea behind The Embroidered Computer, an artwork that looks like an embroidered tapestry but is actually an electromechanical computer that is similar in power to the eight-bit computers of the 1950s. Those mainframe computers filled entire rooms with their wiring, but this computer was made with handmade copper coils, a magnetic bead, and gold and silver conductive thread.
Using traditional embroidery methods, the Vienna-based designers Ebru Kurbak and artist Irene Posch hand-stitched electromechanical switches out of these conductive materials. As with any computer, when an electrical current passes through the copper coil, it creates a magnetic field that causes the magnetic bead to flip to an “on” or an “off” position based on the direction of the current. The entire art piece has a total of 369 switches, which makes up an eight-bit computer that can perform simple calculations.

Following nerve damage, [the] Icelandic composer/producer/musician was unable to play the piano. With his ‘Ghost Pianos’, he gets that ability back, through intelligent custom software and mechanical pianos.
This frames accessibility in terms any of us can understand. Our bodies are fragile, and indeed piano history is replete with musicians who lost the original use of their two hands and had to adapt. Here, an accident caused him to lose left hand dexterity, so he needed a way to connect one hand to more parts.

Comcast is introducing eye control to its X1 cable platform, a new effort that the company says will improve the experience of watching TV for millions of people with physical disabilities. Eye control lets customers change channels, pull up the X1 programming guide, set DVR recordings, and navigate through other menus of the cable box using only their eyes.
Comcast says it’s supporting basically all popular eye gaze hardware and software on the market to make the feature as accessible as possible — including devices from Tobii — plus “Sip-and-Puff switches and other assistive technologies.” Tobii president Tara Rudnicki said, “we are pleased to see how Comcast continues to make their products and solutions accessible.”
For details see the above YouTube video and the complete article from The Verge linked here.
