Turn the page on your e-reader through voice


This DIY device allows a user to turn the page on a Kindle with nothing more than their voice. 


With over 250,000 Americans alone affected by a spinal cord injury, projects like this one from Justin Shaw can prove to have a long-lasting, life-changing impact on a tremendous number of people. Nearly half of those injured are quadriplegic, meaning unable to use their extremities, like Shaw’s friend Steve. One of the most simple things that he missed was the act of reading a book. And while there are e-readers out there, like the Kindle, they still require a user to turn the page. But what if that could be accomplished through the sound of one’s voice?

IMAG0025-650x495

That’s what Shaw set out to do with a DIY system comprised of MCUs, Bluetooth and voice recognition. The first prototype consisted of a big blue button, which when pressed with a forearm, would send an ASCII code for “right arrow” over Bluetooth, turning one page at a time. This worked well until multiple pages turned, and with no back button, it became quite a nuisance.

Upon testing the voice recognition capabilities of an Amazon Echo, the duo wondered if the same technology could be applied to switching pages on a Kindle. And so, the second iteration of the project — entitled Voice Page Down (VPD) — was conceived.

IMAG0138-650x368

“We live in a magical time. VPD would have been a huge undertaking 10 or even 5 years ago. Today, it is practially a drag and a drop,” Shaw explains.

In order to bring this fruition, the Maker employed an Arduino shield stack for most of the project: an EasyVR Shield 3.0 to detect “page down” commands, a Bluefruit EZ-Key module to send HID commands to the Kindle via Bluetooth, and a Power Boost Shield for power management. Meanwhile, VPD is based on an AlaMode MCU (ATmega328P). These electronics are all housed inside a 3D-printed and laser-cut custom enclosure, which also includes a microphone and speaker.

Arduino announces availability dates for the Zero and Wi-Fi Shield 101


Massimo Banzi reveals a U.S. manufacturing partnership with Adafruit, a sister brand and the availability of its latest boards.


Earlier this afternoon, the one-and-only Massimo Banzi took the Maker Faire stage for the highly-anticipated “State of Arduino” address. Undoubtedly, all of us have seen the latest string of stories around the brand name and other challenges it has encountered with its former manufacturer. However, instead of focusing around its ongoing legal battle, the co-founder used the time to share a number of recent advancements to a jam-packed DIY crowd. These included a New York City manufacturing partnership with Adafruit, the launch of a sister brand dubbed Genuino (“genuine” in Italian) for boards outside of the United States, as well as the availability of the Arduino Zero and Wi-Fi Shield 101.

“Adafruit and Arduino.cc have been working together on open-source software and hardware for almost 10 years in a variety of ways, this is expanded partnership and manufacturing is part of our collective goal to make the world a better place through the sharing of ideas, code and hardware with our communities,” Adafruit’s very own Limor Fried shared in response to the big news. “We’re currently manufacturing the [ATtiny85] Arduino GEMMA with Arduino.cc right here in New York City at the Adafruit factory, it instantly became a top seller and we’re looking forward to bringing our manufacturing expertise and processes to start shipping more versions and types of Arduinos right here from the USA as soon as possible.”

Genuino

As for the unveiling of the sister brand, Genuino, this enables “Team CC” to resume production of boards in all of its markets, and allows for more localized manufacturing. MAKE: Magazine’s Mike Senese notes that the new brand will still emulate the 8- and 32-bit chips that Makers have grown accustomed to over the years, such as a Genuino Uno in a familiar teal and white color scheme.

CFJ7MNdUEAAv342-1

What’s more, Makers will no longer have to wait for the release dates of both the Zero and Wi-Fi Shield 101 either. That’s because Banzi revealed that the Zero will be available as of June 9th, and the Wi-Fi 101 Shield not too far after on June 25th. Debuted back at last year’s Faire, the 32-bit board is based on an Atmel | SMART SAM D21 Cortex-M0+ MCU and boasts flexible peripherals along with Atmel’s Embedded Debugger (EDBG) to facilitate a full debug interface on the SAM D21 without requiring any supplemental hardware. Meanwhile, the Wi-Fi Shield 101 is powered by an ATWINC1500 wireless controller and protected with an ATECC108 crypto engine. This provides users with a simple extension that can be seamlessly connected to any Arduino to make way for high-performance, secure Wi-Fi connectivity.

CFJ7MV2UsAAF5OQ-1

Banzi also touched upon a few other key announcements, like the first modular product produced in their Bangalore office, named Modulino, as well as a new set of online tools, known as Arduino Create, that will accelerate the building process for Makers by eliminating the need to switch between various resources.

These movement-responsive wristbands emit real-life superhero sounds


Bam! Pow! Zap! Boom!


If you’ve ever read a comic book, then you’re well aware of the one thing that every superhero has in common: they all have a special power, whether it’s memory manipulation like Professor X, web-spinning and crawling like Spiderman, or x-ray vision like Superman. Unfortunately in print, a reader can’t actually experience the sound effects that coincide with these actions. Instead, they are typically spelt out inside a callout bubble. BAM! POW! ZAP! BOOM! 

c7a0ed196adf5ce735aa8b12e66e721e

Well, Makers Niki Selken and Annelie Koller thought it would be a fun idea to channel their inner superhero by creating what they call Action Bandswristbands that emit sound and light effects as they move. In other words, these wearable devices bring those callout bubbles to life.

To accomplish this, the Maker duo used an Adafruit FLORA (ATmega32U4), an accelerometer, a piezo, conductive thread, a LiPo battery, some NeoPixels, a headband and laser-cut plexiglass icons. These icons were then attached to a store-bought headband and shaped with a sewing machine to fit the wrist.

circuit

From there, the FLORA and accelerometer were connected with conductive thread. The Makers then loaded the code to produce sounds and light effects depending on X,Y and Z coordinates and acceleration. The sounds were compiled from a library created by MIT, while the LEDs employed the Adafruit NeoPixel Library, of course.

“The hardest part was discovering the X-Y-Z access thresholds for the gestures that trigger the sound. We have three unique gesture sets that trigger three different sounds. Part of the fun is finding those gestures and discovering the sounds we programmed,” Selken explains.

12 projects that are redefining storytelling


In honor of World Book Day, here are some Maker innovations that are redefining storytelling…


They say stories can come to life, and well, these projects have taken that saying to an entirely new level.

This isn’t your typical coffee table book

104104647456798521350816554561385745032841n

Jonathan Zufi’s coffee table book entitled “ICONIC: A Photographic Tribute to Apple Innovation is the ultimate must-have for any Apple aficionado. The hardcover recounts the past 30 years of Apple design, exploring some of the most visually appealing and significant products ever created by the Cupertino-based company. The commemorative piece features a special white clamshell case along with a custom PCB configured to pulse embedded LEDs — like that of a sleeping older generation Apple notebook when moved — controlled by an Atmel 8-bit AVR RISC-based MCU.

This magical device will add augmented reality to storybooks 

HideOut-Book

The brainchild of Disney Research, HideOut explores how mobile projectors can enable new forms of interaction with digital content projected on everyday objects such as books, walls, game boards, tables, and many others. The smartphone-sized device enables seamless interaction between the digital and physical world using specially formulated infrared-absorbing markers – hidden from the human eye, but visible to a camera embedded in a compact mobile projection device. Digital imagery directly augments and responds to the physical objects it is projected on, such as an animated character interacting with printed graphics in a storybook.

This interactive piece of art tells a narrative

va_00_lowres

Created by Fabio Lattanzi Antinori, Dataflags is a narrative series of artwork that explores the financial troubles of corporations as they head towards bankruptcy, while highlighting the pivotal role data plays in today’s society. The piece — which was originally displayed in London’s Victoria & Albert Museum back in September 2014 — was powered by Bare Conductive’s incredibly-popular Touch Board (ATmega32U4) and some Electric Paint. The printed sensors were concealed by a layer of black ink, and when touched, triggered a selection of financial trading data theatrically sung by an opera performer.

This book judges you with its cover

a-cover-that-judges-you-by-moore-group-amsterdam_dezeen_468_1

Have you ever judged a book by its cover? Well, Amsterdam creative studio Moore is turning the tables on the old-school idiom by designing a sleeve equipped with an integrated camera and facial-recognition technology that scans the face of whoever comes near. The idea behind the aptly named Cover That Judges You was to build a book cover that is human and approachable-hi-tech. If someone conveys too much emotion – whether overexcitement or under-enthusiasm — the book will remain locked. However, if their expression is free of judgement, the system will send an audio-pulse to an Arduino Uno (ATmega328) and the book will unlock itself. The built-in camera is positioned at the top of the book’s sleeve, above a screen that feeds back the image when it detects a face in close proximity. Artwork featuring abstract facial features is displayed on the cover so that the user can line up their eyes, nose and mouth in the optimum position. Once the correct alignment is obtained, the screen turns green and a signal is relayed to the Arduino that opens the metal lock.

This interactive book lets you feel characters’ emotions

beach2-1024x687_slide-5c7b1107c070d417d3079c31ad6d20fb4da2c8f3-s1100-c15

A team of MIT students unveiled a wearable book that uses networked sensors and actuators to create a sort of cyberpunk-like Neverending Story, blurring the line between the bodies of a reader and protagonist. The sensory fiction project — which built around James Tiptree’s “The Girl Who Was Plugged In” – was designed by Felix Heibeck, Alexis Hope, Julie Legault and Sophia Brueckner in the context of MIT’s Science Fiction To Science Fabrication class. The “augmented book” portrays the scenery and sets the mood, while its companion vest enables the reader to experience the protagonist’s physiological emotions unlike ever before. The wearable — controlled by an [Atmel based] Arduino board — swells, contracts, vibrates, heats up or cools down as the pages of the book are turned. Aside from 150 programmable LEDs to create ambient light based on changing setting and mood, the book/wearable support a number of outputs, including sound, a personal heating device to change skin temperature, vibration to influence heart rate, and a compression system to convey tightness or loosening through pressurized airbags.

This storytelling tree reads with you

img_0853-1_1000x667-720x415-3

In an effort to bring more interaction to story time, Northwood’s Childrens Museum in Wisconsin created a storytelling tree capable of reading along with you. The old computers inside the the museum display were retrofitted with a Touch Board (ATmega32U4) from Bare Conductive. In fact, this was a welcomed replacement as one staff member said that the computers “broke constantly and hogged power, keeping us from updating sounds files periodically throughout the year.”  Unlike its embedded predecessor, the MCU allowed sound files to be changed in an expedited manner, and was slim enough to nestle neatly into the trunk’s design. And what would a treehouse-like exhibit be without a makeshift walkie talkie comprised of cans strung together? Creatively, a set of headphones were also placed inside the can to make it exciting for participants to listen to the story.

This book blends the analog and digital worlds

book-7

Makers Israel Diaz and Ingrid Ocana were on a mission to find new ways to bring children closer to the vast universe of reading. In doing so, the duo figured out a new way to enhance a traditional book with basic electronic components and some Arduino Uno (ATmega328) programming to interact with user intervention through simple built-in sensors, AC motors, LEDs and speakers.

This tale is told with the turn of a music box handle

STory

Night Sun is an interactive audiovisual installation which tells a story with the turn of a music box handle, powered by an ATmega32U4 MCU. In order to bring his idea to fruition, the Maker commissioned an Arduino Micro to control the exhibit. The Arduino was instructed to send a ‘play’ command to a computer when it sensed the touch of a passerby. Once the wired music box handle was turned, the window would light up. A pre-recorded sound would then send a signal to the computer and begin playing… and just like that, the story unfolds.

This pop-up book is made for the digital age

A Maker by the name of Antonella Nonnis recently devised a unique interactive electronic book powered by two ATmega168 based boards. The book, titled “Music, Math, Art and Science,” was inspired by the work of Munari, Montessori and Antonella’s very own mother. The book contains movable parts and uses the electrical capacitance of the human body to activate sounds and lights and other sensors like a button for the math page. Comprised of recycled materials, the book is powered by a pair of Arduino Diecimila, which control the paper pop-up piano and the other controls the arts and science page.

These soft puppets are recreating fables for kids and parents

capano_footprint01-1024x762

Footprints – which was prototyped using an Arduino Uno (ATmega328) – can best be described as a network of interactive soft puppets that help create and share illustrated stories. Designed by Simone Capano, the project links various aspects of a child’s life, including school and family, by collecting and storing relevant data in the cloud. Footprints is typically initiated by a parent. Using a smartphone, the parent can record a little vocal story, add some images proposed by Footprints about the story that was just told, like the story’s characters or other objects related to it. Afterwards, the parent can send it all to the child’s puppet. The child can then listen to the story by placing the puppet on the tablet and playing with the images he or she has received to create a drawing about the story. Once the drawing is complete, Footprints send it back to the parent who then tracks the path of the stories shared with a child via the smartphone app.

This book really sets the scene

Created by Bertrand Lanthiez, Hvísl is described as “an invitation to both a visual and audible journey.” Pre-recorded sounds from Icelandic atmospheres are emitted with the help of electronic sensors hidden in some pages connected to a MaKey MaKey board (ATmega32U4). These effects accompany the reading and the contemplation of pictures from the country’s landscape.

This bookmark makes sure you never miss a part

Tired of having to reread pages in because you forgot which paragraph you left off on? Devised by 7Electrons, the aptly named eBookmark is envisioned to serve as a bridge between analog and digital worlds. The device — which is based on an 8-bit AVR MCU, various Adafruit components, 16 tiny LEDs and a resistive touch strip — allows the reader to save his or her place on the page, and with a switch, also select the left or right page. The top portion of the eBookmark extends for use with larger books.

This fiction machines lets you create your own narrative

photo-1024x768

Who could forget those ‘Choose Your Own Adventure’ books that became popular in the ‘80s and ‘90s? The series of children’s gamebooks where each story is written from a second-person point of view, with the reader assuming the role of the protagonist and making choices that determine the main character’s actions and the plot’s outcome. Similarly speaking, software developer Jerry Belich has created an interactive arcade machine that works on the same premise. The Choosatron is an interactive fiction machine that lets users select the story, while it prints out a transcript of the chosen story paths. In essence, the machine is a cardboard box with a small thermal printer, a coin acceptor, a keypad, an SD memory card and an Arduino-compatible board.

This hoodie can sense and react to weather


This hoodie will emit various lighting effects based on the forecasted precipitation, temperature, and wind speed.


As they say, April showers bring May flowers. Or, in Barbara Eldredge’s case, a flower-covered hoodie that illuminates based on the weather forecast.

hoodie_0025_Screen Shot 2015-04-21 at 7.28.25 AM

The aptly-named Spring Hoodie, which is actually a combination of two inexpensive hoodies from Old Navy, is packed with an Adafruit FLORA (ATmega32U4), a CC3000 Wi-Fi module and a lithium battery, all hidden inside an inner pocket. 18 NeoPixel LEDs were embedded inside of fake flowers adorning the hood. In order to protect and conceal the wiring, the Maker turned one of the two sweatshirts inside-out and placed it directly within other. (Or as Eldredge calls it, create a “hoodie sandwich.”) Just so she never had to take the FLORA out, the Maker also added a button that is tasked with turning the wearable on/off.

“When I turn on the hoodie, the Wi-Fi module tethers to my phone, and the FLORA uses it to connect to a simple PHP web page pulling three-hour forecast data for the predicted precipitation, temperature, and wind speed from the Open Weather Map API,” Eldredge writes.

hoodie_0005_20150421_075310

Once the FLORA is connected over Wi-Fi, the lapel flower emits green to show that it is indeed working. When it connects to the webpage, the ATmega32U4 based MCU collects the weather information and uses it to control the color, brightness and changing of the LED flowers. The color adjusts based on the amount of predicted precipitation. In other words, the more rain that is predicted, the more the LEDs will become blue (and not red/orange).

Meanwhile, the intensity of the LEDs is dependent upon temperature — the warmer, the brighter. Though she wanted some slight pulsing or suggestion of movement in the lights, the speed of this movement is actually dictated by the predicted wind speed. The faster the wind, the faster the lights will change or flicker.

hoodie_0022_Brightness_Contrast%201

“The Spring Hoodie is admittedly a pretty wacky piece of clothing. But after the cold wet winter we’ve had, I’m ready for flowers and color. And I like that it’ll always let me know how the weather’s going to be,” she concludes.

Interestingly enough, for those spring days where you can’t decide as to whether it’s too cold to wear a lightweight jacket, the hoodie will do it for you. Should the temperature dip below an appropriate level, the wearable won’t turn on at all.

Throw on a pair of #Ravespecs for your next party


Wondering what to wear for that party? Make yourself some LED glasses.


What do you get when you combine basic safety goggles, an laser-cut acrylic frame, some electronics and plenty of RGB LEDs? One electrifying pair of #Ravespecs, that’s what. Throw ‘em on and you surely become the ‘light’ of any party.

Screen1

Created by Lorenzo Wood, the glasses were originally a last-minute, thrown-together idea for a friend’s party. Initially conceived as a mask, the Maker felt that glasses would be “a bit more social.” He thought about powering the specs through a remote battery tucked away in his pocket and running wire to the glasses; however, Wood realized that it would be much more fun, portable, and of course, aesthetically-pleasing to make them self-contained.

“In spite of the rushed build and the shoddy wiring, they turned out to be quite robust. The reason that there are wires visible on the front is that for speed I wired the power with just two stripped wires, threading them in and out of the LED strips and connecting them with solder. I don’t recommend that.”

The shades are built around an A-Star 32U4 MCU (ATmega32U4), adorned vertically with Adafruit NeoPixels and powered by standard Lithium AAA batteries mounted to the frame itself. Since the LEDs consume quite a bit of power, a wearer can expect anywhere between one to two hours of continuous use before having to replace its batteries.

Polou

Beyond that, a wearer can easily change the lighting sequences or down the brightness with a little coding, and even try to create designs that don’t engage all the pixels at once, such as strobing rainbow, chasing or police-like effects.

“Because of time, I only had one go at the frame design. I positioned the slits around a typical inter-pupillary distance of 55mm-65mm. In fact, pretty much anyone can see through them (even small children), because the frame is held quite a long way from your face by the safety goggles. The slits could therefore probably be sightly narrower so you could get even more LEDs on.”

With the party now behind him, the Maker reveals that he has already begun working on improving the #Ravespecs. Enhancements include more complex patterns, adding radios for synchronizing more than one pair and enabling wireless controlling, as well as incorporating different sensors. The glasses will be able react in more expressive ways through sound, motion and hand gestures.

See them in action below! If you liked this project, then you’ll love these programmable LED shades from Garrett Mace as well!

Building a life-size Iron Man Hulkbuster suit


A Maker has designed a Hulkbuster costume in homage of the upcoming Avengers 2: Age of Ultron film. 


With Maker Faire Bay Area just around the corner, there’s nothing like some life-size cosplay to spur a little excitement. While we’ve seen a number of pretty impressive Iron Man suits in the past, James Bruton’s latest creation may take the cake. The UK-based Maker has designed a slick Hulkbuster costume in homage of the upcoming Avengers 2: Age of Ultron film.

mock01

“I had planned to build a real life suiting up robot gantry for my Iron Man MKVI build. However, since the suit and its strapping system have progressed, the idea has become less practical. Also, as the Iron Man/Avengers series of films has progressed, Tony Stark has moved away from a special room full of robot arms to do the suit-up, towards suits that put themselves on,” Bruton writes.

With that in mind, the Maker had taken it up himself to create a next-gen getup with Hollywood-like appeal. To complete this task, Burton wanted the suit to not only be self-supporting for when the wearer climbs in and out, but 3D-printed using his Lulzbot TAZ machine and powered by several embedded electronics as well.

Stilts

In order to make the suit free-standing, Bruton designed a set of stilts with space for a remote locking mechanism for the feet and legs. The stilts, along with portions of the frame, were comprised of plywood pieces coated in silver paint and connected by domestic door hinges at its joints.

The Maker included an end stop to prevent overbalancing, along with 3D-printed bearing blocks hinged around the costume’s thigh section and a locking bolt/pin to keep the joint in an upright position. Meanwhile, the joint between the torso and thighs consist of a bungee cord, a 3D-printed rubber buffer piece and plenty of padding to ensure comfort. Bruton also added some snowboard bindings to serve as locking mechanisms for the feet.

handsV2_12

The suit’s 3D-printed hands and forearms even feature Iron Man-esque animatronics, which are powered by an Arduino Uno (ATmega328) in each arm that trigger servos to drive the hand plates. The forearms were designed to have “pop-out weapons” that required various mechanics to hinge backgrounds to point the repulser forward. Another Arduino is embedded within the torso of the suit, and connected by data connectors to activate features located in the body from joysticks in each arm. As for the hand itself, there are three fingers, with the middle one being a bit wider to resemble the suit from the soon-to-be-released flick. These hands are mounted to the suit, and Bruton says cordless screwdriver motors were used to enable the grippers.

“I’m using cordless screwdriver motors to drive the features, these are mounted in pairs on each arm on a 3D-printed bracket with a pulley assembly to pull the finger cords. These parts have to support the arms and allow movement in multiple axis, so I have two spaces for bearings on each axis,” Burton writes. “The elbow hinge will also act as a pulley with another motor to drive the joint, I’ll be springing the arm in the middle of it’s range of motion so that the motor only needs to pull it off centre rather than supporting the whole load around the pivot point. The arm is suspended with a combination of bungee cord and wooden dowel with 3D printed ends. I’m using some larger metal geared motors to drive the elbows — this are Como-Drills 919D motors with an 810:1 gearbox. The bungee and dowels are covered with fake pistons made from PVC pips and 3D printed spacers.”

handsV2_14

As for its shoulders, these will also be open to not only allow the helmet to hinge back, but for the “weaponry” to be revealed. This will be made possible through four-bar linkage and some additional frame parts. One end is hinged on the existing M8 studding which the arms are mounted to, while the other runs into a channel. Bruton notes that the lever mechanism is sprung so that it can stay in either position or be activated by cable control.

Beyond that, the back of the suit is completely open to let a wearer easily hop in and out. As the Maker reveals, its rear panels needed to be able to be remotely activated and while the wearer is inside the suit, in addition to having a safety release for a quick exit in the event of power failure.

Like a number of its other parts, a majority of the chest plates were comprised of foam PVC, plastazote foam and 3D-printed components. The main plate is mounted, enabling the opening of panels on each side of the Unibeam to later hold internal detailing. These parts will be driven by an R/C servo so that they can open and close.

uni06

And, what would Iron Man be without an Arc Reactor? Designed in collaboration with Adafruit, both the Unibeam and Arc Reactor unit are illuminated by a series of NeoPixel LEDs and driven by a GEMMA microcontroller (ATtiny85).

Overall, this may be one, if not, the most elaborate and truly impressive cosplay projects we’ve seen. We wouldn’t be surprised if a few Hollywood producers call Bruton for prop jobs after this display of creativity. Intrigued? You can find an extremely detailed breakdown of the build here, or simply watch his 29-part video tutorial.

ChairVoyager lets you travel the world in under 10 minutes


ChairVoyager is a unique chair and floor mat pair that mentally transports the user through space and time.


Conventional wisdom would tell us that traveling the world can be found on many, if not, all of our bucket lists. However, that requires both time and money. And much of it. Given most of our work schedules, getting off the 80 or so days that it would take to go around the globe is nearly impossible. That’s why the team behind ChairVoyager has developed a way that it can all be done in as little as eight minutes, right from your very own cubicle.

Pic4

Designed as part of a critical making course at UC Berkeley, the aptly named ChairVoyager is comprised of a customized office chair and a vinyl floor mat that mentally transports a user through space and time.

“We believe that transportation is more than a physical movement from one spot to another,” its creators note. With that in mind, the group of students wanted to explore the idea of feeling as if you traveled to far away places without actually having to hop on a plane, find a place to stay, and of course, navigate unfamiliar land.

Pic3

The ChairVoyager works by moving around an office chair along a mat covered in vinyl cutouts representing each continent. As the piece of furniture moves along the floor, an embedded light color sensor below the chair detects what country it has landed upon and a built-in speaker system emits curated news podcasts from that specific region. The team notes that the noise is very low-key, which makes it perfectly suitable for any office setting, should the urge to travel world come about. The stories being heard are also shared via Wi-Fi with the user’s mobile device for future reference.

The bold colors of each vinyl cutout that denote each continent make it clear where one ends and another begins. Beyond that, the white background portraying the ocean can be programmed to play naval-related news or whale songs as well.

“We originally designed ChairVoyager for office workers. We want to make it easy to catch up on current global even, and allow their mind to explore and connect to the larger world. And we saw their breaks, as they kick back with a relaxed gaze and listen to their ChairVoyager travels, as the perfect opportunity to do this.”

Pic2

In order to bring this project to life, the team equipped an everyday office chair with a SparkFun audio breakout board, an Adafruit Wi-Fi module breakout board, an Adafruit RGB color sensor at its base (just above the floor), and a 6V power supply directly under the right armrest. These electronic components were are all integrated into one SparkFun RedBoard (ATmega328) and housed inside an aluminum case. Meanwhile, a “surround sound quiet speaker” was installed in place of its existing headrest, so that the stories would be played close to the user’s ears — without distracting other colleagues.

Maker decks out his wingsuit with 300 LEDs for a night jump


We’re not quite sure what it is, but there’s certainly something magical about watching hundreds of LEDs fly brilliantly through a night sky.


In preparation for this most recent jump, skydiver Nikko Mamallo embedded his Squirrel FUNK wingsuit with 10 Adafruit NeoPixel strips — three in each wing, four in the tail. As you can imagine, with 300 animated LEDs in total, this made for one unique experience. (Not to mention, countless “UFO sightings” from onlookers.)

CBlxBCnUMAA_t5G.jpg-large

According to Mamallo, the entire build took approximately two months to go from mere concept to flight. The LEDs were programmed using an Adafruit Pro Trinket (ATmega328). The Maker also added a NeoPixel status light to the board, a trigger switch to start the LED animations inside his wingsuit belly pouch, and a killswitch in his glove to turn the lights off/on if necessary.

“Though I built this with the skydiving environment in mind, there are a few things I’d change for a V2 to make it a little more robust and durable as I did break one of the strips on the daytime test flight when I crushed it sitting on the floor of the caravan and I did have a data short on my left wing from a loose data cable,” Mamallo writes.

Footage of the late night dive from 13,000’ was captured using a GoPro Hero 3+ Black and a GoPro Hero 4 — which you can watch below.

These smart socks will let you know what’s up in the washer


Get ready for the I-o-Feet.


When you think of the billions of “things” that will one day be connected to the Internet, socks may not be one of the first items that come to mind. However, as recent reports have suggested, the smart clothing and electronic textile segment is expected to grow by leaps and bounds, so it was only a matter of time before the IoT would head to our feet.

First reported by our friends at Adafruit, Maker Guido Burger has developed an intelligent sock prototype packed with a LilyPad ProtoBoard, a LilyPad RGB LED, an Arduino Pro Mini (ATmega328), and most importantly, an Adafruit FLORA 9 DOF sensor. The sensor is tasked with driving the RGB LED and enables a user to do one of two things: monitor the sock during the washing process and find answers to questions that they may’ve never thought about. For instance, have you ever wanted to know how many g-forces a sock has to survive or how many times will it be washed?

The idea was first conceived after Burger had been working on a smart home hack. When presented with the option of a smart oven, fridge or washing machine, he decided the latter was the most interesting one.

“Because why the heck do you need a smart washing machine at all? They are already smart (weight sensor, special washing programs), but I got interested as the cloth in the washing machine was not at all connected,” the Maker reveals. “So, taking the possibility to transmit data from a sensor being under water was a great basis – a must have.”

While working on the project, Burger discovered that he needed to coat the electronic components with acrylic resin — except on the through-holes for the conductive thread. The Maker also tells Adafruit that he switched from a LiPo battery to a coin cell, as it had a better rating for this rough and tumble temperature changing life.

With the prototype complete, the Maker has embarked on the next iteration of the smart sock. This time, it will be equipped with Bluetooth Low Energy, which will allow for it to work with an accompanying app to collect and visualize data from a smartphone. As seen in previous projects from Burger, Platinchen (or blueIOT) is a platform from Fab-Lab Germany that combines a certified BLE module along with an ATmega328P MCU.
