Vendredi, Février 7, 2014 - 22:30Make Your Own Hylian Shield
When you’re tackling a costume, do you ever worry about not having the required skills? Everyone is a beginner at some point, and all you can do is jump in and try. Cosplayer Vy didn’t know how to work with wood or metal or painting before she made props for her Link costume, but it didn’t stop her. Vy decided she needed a Hylian shield and figured it out. She started with thin plywood and went from there – she documented the process with words and comics at her blog. Here’s how she got started:
I drew half a shield on a giant piece of paper, folded in half. Cutting it out this way will ensure that your shield is properly symmetrical!
See how the Hylian Shield has that nice silver border? After cutting the shield shape out, I hand-copied the border shape onto my stencil and cut that out as well. Keep it folded when you do so that the border is also symmetrical!
Using this stencil, I drew two shapes on my plywood: One for the shield, and one for the border.

Vendredi, Février 7, 2014 - 22:30Mapping where people run
Nathan Yau from FlowingData created beautiful maps by using publicly accessible exercise app data:
There are many exercise apps that allow you to keep track of your running, riding, and other activities. Record speed, time, elevation, and location from your phone, and millions of people do this, me included. However, when we look at activity logs, whether they be our own, from our friends, or from a public timeline, the activities only appear individually.
What about all together? Not only is it fun to see, but it can be useful to the data collectors to plan future workouts or even city planners who make sure citizens have proper bike lanes and running paths.

Vendredi, Février 7, 2014 - 22:00Reverse Engineering A Bank’s Security Token
[Thiago]‘s bank uses a few methods besides passwords and PINs to verify accounts online and at ATMs. One of these is a ‘security card’ with 70 single use codes, while another is an Android app that generates a security token. [Thiago] changes phones and ROMs often enough that activating this app became a chore. This left only one thing to do: reverse engineer his bank’s security token and build a hardware device to replicate the app’s functionality.
After downloading the bank’s app off his phone and turning the .APK into a .JAR, [Thiago] needed to generate an authentication code for himself. He found a method that generates a timestamp which is the number of 36-second intervals since April 1st, 2007. The 36-second interval is how long each token lasts, and the 2007 date means this part of the code was probably developed in late 2007 or 2008. Reverse engineering this code allowed [Thiago] to glean the token generation process: it required a key, and the current timestamp.
[Thiago] found another class that reads his phone’s android_id, and derives the key from that. With the key and timestamp in hand, he figured out the generateToken method and found it was remarkably similar to Google Authenticator’s implementation; the only difference was the timestamp epoch and the period each token lasts.
With the generation of the security token complete, [Thiago] set out to put this code into a hardware device. He used a Stellaris Launchpad with the Criptosuite and RTClib libraries. The hardware doesn’t include a real-time clock, meaning the date and time needs to be reset at each startup. Still, with a few additions, [Thiago] can have a portable device that generates security tokens for his bank account. Great work, and great example of how seriously his bank takes account security.

Vendredi, Février 7, 2014 - 21:44NEW PRODUCT – Adafruit 9-DOF IMU Breakout – L3GD20 + LSM303
NEW PRODUCT – Adafruit 9-DOF IMU Breakout – L3GD20 + LSM303 – This inertial-measurement-unit combines 2 of the best quality sensors available on the market to give you 9 axes of data: 3 axes of accelerometer data, 3 axes gyroscopic, and 3 axes magnetic (compass). We tested many different ‘combination’ sensors and found these were the best value, with stable and reliable readings.
The L3DG20 gyroscope + LSM303DLHC accelerometer/compass sensors are all on one breakout here, to save you space and money. Since all of them use I2C, you can communicate with all of them using only two wires. Most customers will be pretty happy with just the plain I2C interfacing, but we also break out the ‘data ready’ and ‘interrupt’ pins, so advanced users can interface with if they choose. A 3V regulator with reverse-polarity protection means you don’t have to worry about frying the boards by accident. There’s level shifting circuitry so the IMU can be used with 3 or 5V logic boards. And check out those mounting holes! You can securely attach this board to your rocket, robot, art project.
Each order comes with one assembled and tested 9DOF breakout board and a small piece of header.
- L3GD20 3-axis gyroscope: ±250, ±500, or ±2000 degree-per-second scale
- LSM303 3-axis compass: ±1.3 to ±8.1 gauss magnetic field scale
- LSM303 3-axis accelerometer: ±2g/±4g/±8g/±16g selectable scale

This is the first time I’ve done a project that I design, etched, soldered and programmed and works directly the first time without any hassle of unsoldering or repeating the process again. It feels like you are inside a casino with chips in your hand and you are tempted by the house to win all the time ” (read more)
Community Projects from the Adafruit Blog
The folks over at Raspberry Pi have dubbed this pan flute project “music hack of the decade”: “Panflute Hero was the result of a weekend at Way Out West Hackathon 2013. It’s a very silly panpipe version of Guitar Hero, which doesn’t use a plastic guitar controller. Instead, it’s controlled by a hand-built, bamboo set of faux panpipes (which are built according to the Golden Mean), all equipped with Arduino sound sensors that detect blowing, and controlled by a Raspberry Pi sending “blow” events to a desktop over TCP. Simulated flute noises are emitted when a “blow” is sensed, and…well, see for yourself.” (read more)
A team at Chico State University designed The Safety Attention Monitor (SAM) using a raspberry pi, leds, and more to help drivers to stay focused behind the wheel: “The team designed SAM using OpenCV to track your face in order to recognize when you aren’t watching the road. It alerts you through a variety of audible beeps and LED lights, and is programmed to only alert you after set time values — i.e. it’s not going to go off when you’re checking your blind spot, unless you’ve been checking it for over a certain length of time. It also has a silence button you can press for situations like looking around while you are parked. The proof of concept device was built using a Raspberry Pi, the PiCam, and a breadboard to accommodate some manual controls, the buzzer, and LEDs. It also continuously records video of you on a 30 second loop, and in the event of an accident, it saves all the video — perhaps proving it was your fault. Can you imagine if all cars had this installed? On the plus side you wouldn’t have to argue with insurance companies — but if it really was your fault, well then you’re straight out of luck.” (read more)
Every Chell costume needs a portal gun, and Redditor Pastlightspeed put one together on the cheap. She wanted to carry it during a 5K run, so it was also important that the weapon be lightweight. She put the gun together for less than ten dollars with cardboard. No excuses — you need one of these! (read more)
Lasercut Castell Construction Kit by vellab – Thingiverse Thing 240571: “‘Castell‘ is a human tower built traditionally in festivals at many locations within Catalonia. I’ve seen it several times in TV but watching it live in Barcelona was a totally astonishing experience. This is my version of homage to castellers.” (read more)
Sandy Noble shared a Polargraph project using an Adafruit Motor/Stepper/Servo shield for Arduino v2. kit! “The whole system is fairly technologically agnostic, but the current incarnation uses an Arduino microcontroller and an Adafruit Motorshield, along with a couple of stepper motors. The application that drives it from the computer is written in Processing. It decodes a bitmap and creates a map of the file using a polar coordinates system, recording pixel position, size and brightness. The hardware requests each pixel in turn, and renders it on the page using it’s own shading and movement algorithms.” (read more)
The G Ball from Argonaut Industries uses an Adafruit TRINKET, LSM303 & NeoPixels: “The G Ball is a Nerf-style soccer ball studded with lights which respond to the motion of the ball. When held in your hand, the lights are yellow on the top of the ball, green on the bottom, regardless of how you rotate the ball. When the ball is in free-fall (flying through the air, for instance), the lights turn blue. When the ball experiences a sudden acceleration (when being thrown or caught), the lights flash red.” (read more)
Customizable Super Flowers (drooloop flowers) by peetersm on Thingiverse as Thing 240158: “Make your own unique one-of-a-kind flowers with this openSCAD file! Print beautiful flowers as a gift for that special someone, or just to help decorate your world. They print fast and easy (see instructions). Get creative and incorporate flowers into other models or for fashion (see picture of the tie jewelry).

Sean Charlesworth shared his devotion to Adafruit and the Minty Boost kit through his excellent walkthrough tutorial for how he created a 3D printed enclosure for his kit: “I am a huge fan of Adafruit Industries, which was founded right here in NYC by MIT engineer, Limor ‘Ladyada’ Fried and is a supplier of great DIY electronics projects and an excellent source of information. Adafruit hand-picks quality electronic components, designs their own boards and kits and has an amazing tutorial section. I am no electronics wiz and have managed to put together some pretty cool stuff with their guidance. I love this place. One of Adafruit’s first kits was the MintyBoost USB charger which you solder together yourself, runs off of two AA batteries and fits in an Altoids mint tin. Throw one in your bag and they are super handy when you need an emergency phone charge. It’s worth the looks you get when plugging your phone into an Altoids tin. I’ve built five of these and from those builds thought of two improvements I wanted to make. The first problem was if the batteries were left in for an extended period of time they would eventually discharge to the point that they would leak and I killed two MintyBoosts this way. The second thing I wanted was enough room in the case to fit a small charge cable, so I decided to design and 3D print my own enclosure.” (read more)
Why did the Raspberry Pi click the link? To check out this detailed tutorial by mazzmn on how to make a joke machine that will leave you in stitches (ba-dum-ch): “I recently received a new Raspberry Pi and wanted to create an Intro to Raspberry Pi project. My Pi included a 16×2 LCD display and a Wi-Pi Card so I created the Wireless Raspberry Pi Powered Joke Machine. Just press the push-buttons and the machine will look up a one-liner and scroll through it. (Admission of guilt here…I originally thought it would be neat to create a desk-toy that could display inspiring and educational famous quotes…the Joke Machine can do this, but when I found I could just as easily generate one-liners, I decided that would be more fun ) This Step by Step Instructable walks you through the process of setting up a new Raspberry Pi, adding the the PiFace Control and Display LCD, the WiPi wireless and the provided python script TheQuoteMachine.py which looks up jokes and quotes on a free service called iheartquotes.com. it’ll also describe how to access your Pi without need for a keyboard or Display using VNC remote access.” (read more)

Vendredi, Février 7, 2014 - 21:283D Printing: Coming to a Classroom or Museum Near You
Maureen Kelleher reviews the growing trend of libraries and museums carrying and using 3D printers in educational exhibits, via remakelearning.org:
If 3D printing—which builds an object layer by layer based on precise, computer-assisted design specifications—hasn’t come to a school or museum near you yet, you can bet it’s on its way. Some industry watchers predict 2014 will be a big year for 3D in the classroom. While top-of-the-line models still cost a pretty penny, CNN has reported some smaller, stripped-down 3D printers are selling for only $200-$300.
The technology has already made quite a splash. As Pittsburgh’s own Gregg Behr, executive director of the Grable Foundation, recently pointed out in the Huffington Post, “People are already using 3D printers to make edible food and artificial body parts (what?!).” No kidding. (Read more about those body parts here.)
Since 2011, DIY-ers of all ages have flocked to the Children’s Museum of Pittsburgh for a chance to play around with the 3D printer in its MAKESHOP. “I’m a big believer that if you provide materials for kids and if you provide them with inspiration and you provide them with mentors, they will be inspired,” Jane Werner, the museum’s executive director, told us last year.
Or animal skeletons, or archeological finds from ancient civilizations, or other replicas of artifacts students don’t normally get to touch. At New York City’s American Museum of Natural History, students explore the intersection of paleontology and technology by examining allosaurus bones and using 3D printing to make a model skeleton. “It really taught me how paleontologists reconstruct and study dinosaurs and how they deal with disarticulated bones…and broken bones,” said Jordan, an 8th-grader, in this video about the experience.
At The Browning School in New York City, kindergartners aren’t just baking cookies—they’re making the cookie cutters, too. Engineering has become part of the curriculum across the grades, from 3D-printed cookie cutters to homemade Lego-style building blocks. You can see photos and video of their work here.

Vendredi, Février 7, 2014 - 19:10STEM Kits for Preschool and Kindergarten
Check out these STEM Kits for Preschoolers and Kindergarteners from hatch early learning:
The U.S. Department of Education began the STEM federal initiative for preschool in 2011. There are no greater natural scientists and engineers than young children; they are inquisitive and naturally learn as they play. Our STEM learning center, the lessons in the Activity Guide, and the materials in this Kit provide children with structure to build upon their natural inclination to explore, to build and to question. To learn more visit our blog post by Hatch expert, Jenne Parks…
…For each kit the activities are scaffolded, presenting information and ideas with increasing complexity to give children an introduction to the basic concepts of technology and promote literacy and other school readiness skills along the way. Each kit also comes with unlimited access to video-based online courses to help your teachers make the most of the kit in the classroom.
Vendredi, Février 7, 2014 - 19:00Hackaday Retro Edition: Retro Roundup
Inspired by the Palm Lifedrive in the previous retro roundup, [Bobby] dug out his Palm TX and loaded up the retro edition with the Blazer browser. Given this device has WiFi and a browser, it’s not much, but [Bobby] did run in to a bit of a problem: Palm never released WPA2 for personal use, and this device’s WPA abilities are buried away in a server somewhere. Interesting that a device that’s relatively young could run into problems so easily.
How about another Palm? [nezb]‘s first smartphone, back in 2003, was a Treo 600. He dug it out, got it activated (no WiFi), and was able to load the retro edition. Even the Palm-optimized edition of Slashdot works!
How about some Xenix action? [Lorenzo] had an Olivetti 386 box with 4MB of RAM with Xenix – Microsoft Unix – as the operating system. The connection was over Ethernet using a thinnet card. Here’s a video of it booting.
[Eugenio] sent in a twofer. The first is a Thinkpad 600, a neat little laptop that would make for a great portable DOS gaming rig. It’s running Mandrake Linux 9, his very first Linux. Next up is the venerable Mac SE/30 with a Kinetics Etherport network card. It’s using a telnet client to talk to a Debian box.
Here’s one that was cool enough for its own post: [Hudson] over at NYC Resistor salvaged an old Mac SE with a BeagleBone Black connected to the CRT. This effectively turns the SE into a modern (if low powered) ARM Linux box. Emulators are always an option, though, as is loading our retro edition in xterm.
Links to the pics below, and you’re always welcome to dust off your old boxxen, fire it up, and load up the retro edition. It’s new and improved! Every half hour or so, five classic hacks from the first 10,000 Hackaday posts are converted to pure HTML. Take a pic and send it in.

Vendredi, Février 7, 2014 - 17:21The Michelangelo of Lego Who Quit Law to Play With Toys
Kevin Fallon’s profile of Nathan Sawaya in the Daily Beast chronicles the famed lego artist’s transition from corporate lawyer to a mini-brick laying specialist with an eye for re-imagining iconic paintings:
While still working at his law firm, Sawaya would post his finished Lego sculptures on a website, brickartist.com. Soon, he was getting commissions to create custom pieces. Then requests started pouring in from all over the world. One day his website crashed because it was getting so many hits, he says, “so I left the law firm to play with toys full time.”
It wasn’t an easy transition. His colleagues and his family thought he was out of his mind. Quit corporate law to play Lego … can you blame them? Other reactions ran the gamut. “Some of my colleagues were jealous because I was following my passion,” Sawaya says. “Others were just confused.” But even after making the decision, it wasn’t all child’s play (heh) to go from the lifestyle of a lawyer making six figures to the lifestyle of an artist, unsure of whether he can pay rent each month.
“In 2007, I got my first solo show,” Sawaya remembers. “At the time I thought it was going to be my last solo show.”

As always, we keep you updated with the latest Raspberry Pi book reviews and upcoming events.
Vendredi, Février 7, 2014 - 16:59MakerBot Stories | How Architects Can Build a City of Ideas
Buildings designed today may not open for a decade, so architects make models to help people understand the future. Before presenting ideas to the clients, governments, and communities who must buy into (and pay for) their vision of the future, architects need to envision it themselves, through sketches, computer renderings, animations, and physical models.
“The earlier you can look at a physical object, the sooner you can understand a building and also make better design decisions,” says W Scott Allen, an associate architect and designer for Perkins+Will, a global architecture firm that has seven MakerBot Replicator 2 Desktop 3D Printers in its offices.
On a recent morning, Allen set out more than 40 six-inch towers on a conference room table at the global architecture firm’s New York office. The towers, process models used to reimagine the space around the Bernardine Monastery in Lviv, Ukraine, ranged from thin spires to fat blocks to something resembling a stack of old Life Savers. “You might have an entire set of models that are exceptionally functional and some that are wildly impractical but just look really awesome,” said Allen, who made these models on a MakerBot Replicator 2.
Rapid prototyping “profoundly changes our own creative process,” says Allen, who will set up the 3D printer before going home for the evening, returning the next morning to analyze the models with his colleagues. Then Allen will go back to the computer and generate new designs for the next night’s print run.
“Making all of these on the MakerBot frees us up to test more ideas for clients and come at a nicer solution in the same timeframe,” says Allen. The great thing, he adds, is that “you can almost print at the same speed that you can draw.”
Vendredi, Février 7, 2014 - 16:38Program a Yún without writing code! Temboo’s Sketch Builder
Today’s guest blogger Vaughn Shinall from Temboo‘s team updates us with a new feature to ease your way into smart homes.
Choose your sensor, choose what action you want it to trigger, and voila–your Arduino Yún is doing it. Sending texts when a light sensor detects night, logging temperature data to a Google spreadsheet while you’re away, calling you when it sees an intruder in your home.
With our new Sketch Builder you can program your Yún to do all these things and more in no time. After choosing from multiple sensor types and actions, you can set the conditions and pins for your set up and have the code generated in an instant right on Temboo’s website. Then it’s just a simple copy-paste-upload job, and you’re on your way.
Go give the Sketch Builder a try today. Support for more sensor types and actions are on the way, so let us know what you’d like us to add.
Watch the Sketch Builder in action:
PS – You should also check out this cool Arduino Yún project where the user managed to get Temboo running straight from the board’s Linux distribution by installing the Temboo Python SDK on the Yún.
Vendredi, Février 7, 2014 - 16:01Thumbs-Down Songs on Pandora with Your Mind
[Steven] likes music. Like many of us, he uses Pandora to enjoy the familiar and to discover new music. Now, Pandora means well, but she gets it wrong sometimes. [Steven] has had a Mindwave Mobile EEG headset lying around for a while and decided to put it to good use. With the aid of a Raspberry Pi and a bluetooth module, he built a brainwave-controlled Pandora track advancing system.
The idea is to recognize that you dislike a song based on your brainwaves. The Mindwave gives data for many different brainwaves as well as approximating your attention and meditation levels. Since [Steven] isn’t well-versed in brainwavery, he used Bayesian estimation to generate two multivariate Gaussian models. One represents good music, and the other represents bad music. The resulting algorithm is about 70% accurate, so [Steven]‘s Python script waits for four “bad music” estimations in a row before advancing the track.
[Steven] streams Pandora through pianobar and has a modified version of the control-pianobar script in his GitHub repo. His script will also alert you if the headset isn’t getting good skin contact, a variable that the Mindwave reports on a scale of 0 to 200.
Stick around for a demo of [Steven] controlling Pandora with his mind. If you don’t have an EEG headset, you can still control Pandora with a Pi, pianobar, and some nice clicky buttons.
