Mercredi, Février 19, 2014 - 21:51Reebok CheckLight Teardown #WearableWednesday
The Reebok CheckLight is a sports activity impact indicator for athletes at risk of head injury, like football and hockey players. The lights at the back of the neck light up in reaction to severity and cumulative number of head impacts as sensed by an accelerometer and gyroscope. Check out the guide on the Adafruit Learning System for more closeup photos and a list of the parts on the board.

Mercredi, Février 19, 2014 - 20:58Bi-Color 24 Bargraph – Control small LED matrices with ease
This version of the LED backpack is designed for these bright and colorful bi-color bargraph modules. Each module has 12 red and 12 green LEDs inside, for a total of 24 LEDs controlled as a 1×12 matrix. We put two modules on each backpack for a 24-bar long bargraph (48 total LEDs).
This backpack solves the annoyance of using lots of pins or a bunch of chips by having an I2C constant-current matrix controller sit neatly on the back of the PCB. The controller chip takes care of everything, drawing all 48 LEDs in the background. All you have to do is write data to it using the 2-pin I2C interface. There are three address select pins so you can select one of 8 addresses to control up to 8 of these on a single 2-pin I2C bus (as well as whatever other I2C chips or sensors you like). The driver chip can ‘dim’ the entire display from 1/16 brightness up to full brightness in 1/16th steps. It cannot dim individual LEDs, only the entire display at once.
Mercredi, Février 19, 2014 - 19:54This Mind-Reading Bicycle Helmet Will Tell You When You’re Stressed #WearableWednesday
Biking reduces stress. That is, until you hit the pavement and start weaving in and out of traffic, pedaling alongside cars, trucks and a string of crowded buses. City cycling is an unnerving experience — one that’s bound to leave you perpetually paranoid you’ll be pummeled by the poorly-planned opening of a car door.
Arlene Ducao, a recent MIT Media Lab graduate, has felt a similar anxiety biking around New York City. To stay safe, she smartly straps on a helmet. Not just any helmet, however; one that reads minds.
Ducao has been working with Ilias Koen, whom she met at New York City’s School of Visual Arts. Together, they’ve spent the last decade focused on scientific data visualization, all while tricking out their bike helmets, rather recreationally, with different caps and lights to make it more visible.
MindRider is a helmet that’s undergone several “rounds.” The first? Translating the cyclist’s brain state to different colors on the helmet, similar to traffic lighting. Green is equivalent to calm and focus, while yellow represents slight agitation, and red equates to stress and a blinking red light symbolizes panic. The coloring is a way to present bikers’ mental state on the streets, according to Koen, although that’s just one way stress can be used.
The helmet is also capable of developing “Experience Maps” of cyclists’ geo-located brain activity. With these maps, MindRider is able to analyze relationships between the user and the environment, and assist other riders in charting a safer course.
“The data access of MindRider has evolved into something more useful for them,” said Ducao of the startup’s initial cyclists. “They could look up a map of all the users and all of the brain states and use that to plan their route.”
Knowing where you get stressed and others get stressed isn’t just helpful personally, however. The feature can also aid municipal government organizations looking to more effectively plan out bike lanes in their city. All data is customized to a user’s privacy settings, yet MindRider encourages cyclists to “add to street maps that show [their] community’s experience” and “share them with friends, other cyclists, even transportation planners.”
Mercredi, Février 19, 2014 - 19:44How to make a “thing” - Lessons from the founder of @littleBits
My name is Ayah Bdeir, I’m the founder and CEO of littleBits, an open source library of electronics that snap together with magnets for prototyping, learning and fun. Each “brick” has essentially one function — light, sound, sensor, motors, logic—and the bricks come together to form larger circuits that can do anything: from an obstacle-avoiding robot, to acrayon lathe, to an interactive toy.
We have been called “LEGO for the iPad generation” but I’d like to think littleBits is much more, it is a versatile, age-agnostic, gender neutral hardware platform — the most extensive and easy to use invention platform in the world.

Mercredi, Février 19, 2014 - 19:01A Digital Condom a Reality Thanks to Arduino
[Bill Gates]‘ foundation is currently offering up a ton of prizes for anyone who can improve the condom. It’s a laudable goal, and somewhat difficult; one of the main reasons why male condoms aren’t used as often as they should is the, ”male perspective… that condoms decrease pleasure as compared to no condom.”
While most of the work inspired by the [Gates] foundation is work investigating a change in the geometry of the condom, [Firaz Peer] and [Andrew Quitmeyer] of Georgia Tech managed to solve this problem with an Arduino.
The basic idea of the Electric Eel – yes, that’s the name – is to deliver short electric impulses, “along the underside of the shaft for increased stimulation”. These impulses are delivered in response to different sensor inputs – in the video example (surprisingly safe for work) they’re using a force resistor wrapped around the chest for an electrical stimulation with every breath.
Although this is only a prototype, the hope is the conductors in the condom can eventually be implanted along the inside surface of a condom during manufacturing.
Video after the break.

Mercredi, Février 19, 2014 - 18:51It’s a Bird! It’s a Plane! It’s a Fendi Drone! #fashion #drones
Via The Cut.
Fendi is going to broadcast its fall/winter 2014 show on Thursday not just by regular photography or video, but by drone. A fancy little bot will fly above the runway during the show, taking aerial pictures with a high-definition camera that will be immediately visible on the show’s live-stream. This confirms our sneaking suspicions: Live-streams really are better than going to the actual show.
The Fendi drone, which the house hails as “an innovative project” that “surpasses the traditional notion of fashion shows,” is supposedly a sign of Fendi’s commitment to innovation and creativity — but demonstrates no discernible link to Jeff Bezos’s Amazon drones that will soon take over the world. To us, the Fendi drone just sounds like a good way to mix up the tried-and-true format of a fashion show.
But the real question: Will Fendi put them on key chains? The new Fendi bug bag: the Fendi drone bag?
Mercredi, Février 19, 2014 - 18:07NEW PRODUCT – Infragram DIY Plant Analysis Webcam
NEW PRODUCT – Infragram DIY Plant Analysis Webcam – Use this specially modified webcam to analyze plant health, in combination with the Infragram.org image processing tool to measure photosynthesis. Based on the same multi-spectral satellite imaging techniques used by NASA, this USB camera lets you take simultaneous infrared and visible photographs at 1600×1200 pixel resolution.
The pre-installed filter (also sold separately if you want to convert your own camera) allows you to take an infrared photo in the “red” channel of your camera, and a visible image in the “blue” channel. These can be used to measure photosynthetic activity; you can read more about the technique here and here.
This technique was developed by contributors to the Public Lab, an open network of collaborators who develop affordable environmental science tools. Weighing less than an ounce, it’s perfect for connecting to your laptop, a Raspberry Pi, or a mobile sensing platform, and with unscrewable lenses and no infrared-block filter, it can be adapted for other uses as well.

Mercredi, Février 19, 2014 - 16:00Audio Networking With GNU Radio
Thought GNU Radio was just for radio? Think again. [Chris] has been hard at work turning the signal generation and analysis of the best tool for software defined radio into a networking device for speakers and a microphone.
The setup uses GNU Radio to generate a carrier signal whose frequency is modulated with a data stream. With this modulated signal piped over a laptop’s speakers, [Chris] is able to send UDP packets across his desk using nothing but sound.
[Chris] had recently used a similar technique to transmit data via audio with GNU Radio, but this latest build is a vast improvement; this is now a duplex networking, meaning two computers can transmit and receive at the same time.
In the end, [Chris] created a strange, obsolete device called a “modem”. It’s not exactly fast; sending ‘Hello World’ takes quite a bit of time, as you can see in the video below.

My final project I made for my video productions class “Cutaway Productions” (Search them for their channel) at my high school. I don’t own the rights to the song or the pictures and I am not trying to claim them, I just did this video for fun and i spent many a hour on it.
Mercredi, Février 19, 2014 - 15:15Making Elektra’s Sai
Elektra Natchios’ weapons of choice are two sai. Karen Cosplay made an Elektra costume based on Kotobukiya’s Bishoujo statue. She used metallic red lycra for the costume and constructed the sai from papier mache, spackle, and craft foam. She put the process together in a photo tutorial, and it’s opened my eyes about using spackle for sculpting. Check it out:

Generating Embroidery with an Arduino on Hackaday:
Embroidermodder is an open source tool for generating embroidery patterns. It generates a pattern and a preview rendering of what the embroidery will look like when complete. It’s a cross-platform desktop application with a GUI, but the libembroidery library does the hard work in the background. This library was ported to Arduino to pull off the hack.
