    UV-Detecting Hat with FLORA #WearableWednesday


    IMG_0606

    Liz in the Adafruit forums writes:

    You can’t really see without a video, but the display alternates between showing the current UV index and the total exposure since turning the hat on. When the exposure display fills all the pixels, I’ve reached the ‘barely perceptible 24 hours later sunburn’ level and it’s time to go inside. I plan to keep the hat on my desk at work for lunchtime excursions. I don’t normally wear sunscreen to work, so having the hat to keep track of my exposure is really practical.

    Code Mode Light


    Adafruit 2964

    Code Mode Light @ Fairgoods.

    Jessica Hische has spent a lot of time learning web design and development over the past few years — and a lot of time asking her husband for help. “I noticed his concentration was impenetrable when he was coding and to bring him out of it was to wish death upon yourself. Once I started doing web work myself I would go intosilence zone mode or code mode often. Now I use the term to describe any time I’m in the zone with work and can ignore just about everything else.” She wanted to make something for her wall to let her studio mate know her code mode status, “so he wouldn’t think I was ignoring him. I just get too deep in work to know when he’s talking to me!”

    Jessica hand-lettered the words IN CODE MODE, and the light itself — which is made from powder-coated steel, powder-coated white aluminum, and translucent vinyl — was built by Palette Industries.

    You could make/mod a net-connected version or one that knew you were actually coding too!

    LED Bib Necklace #WearableWednesday



    Agy writes:

    I’ve always wanted to make a bib necklace but didn’t get around to doing it as I wasn’t really sure what materials to use. Then a friend passed me an old jean skirt that no longer fitted her toddler. I used the jeans as the necklace base and strengthened it with felt. I added black lace scraps from the upcycled LBD project, a few Swarovski crystals (a few because they were so expensive!) and a couple of craft gems. The project was finished off with a black ribbon.

    To give the project a sparkle, I sewed on the LilyPad board, light sensor and LED lights. This project glows when it is dim or dark, and flickers when it is bright. You don’t have to do the electronics, but I think I’m hooked ever since doing the blink bike bag! Read below for the tutorial.

    Sci-Fi Contest Roundup: Science Nonfiction

    Yep, we have a Sci-Fi contest on our hands, with a week to go until entries are due. There are amazing prizes for the best Sci-Fi build, but in the spirit of the Internet, a few teams have elected to put together a science nonfiction project. We won’t hold that against them, because these builds are really, really cool.

    Rockin’ bogie, man

    rockerFirst up in the ‘real life science fiction’ category is an adorable little rocker bogie robot designed and built by a team at MADspace, the Eindhoven Hackerspace.

    A rocker bogie suspension is rather unique in that it can be used to drive over obstacles twice the size of the wheels, has a zero turning radius, and is found on every rover that has ever gone to Mars. The suspension system has articulated rockers on each side of the chassis , with pivoting wheels at each of the four corners of the robot. While this type of suspension can’t go very fast, it can go just about anywhere.

    The team loaded up their bot with a Raspberry Pi, a pair of webcams, 20Ah of batteries, gyro, and a web interface. The suspension works beautifully, and most of the parts are 3D printable. Very cool. There’s a pair of videos with this bot in action below.

    Spider bot. Just add two more legs.

    Hex

    Continuing on with the science nonfiction theme of this post is a cute little hexapod walker reminiscent of designs that have been proposed to visit the moon and asteroids.

    This is a rather unique hexapod, controlled entirely with 12 PWM channels on an ATMega1284. Although each leg only has two degrees of freedom (the software has support for 3 DOF, though) the movement is surprisingly smooth. It’s an inexpensive build, too, with 5 gram servos providing all the power to the legs. Video below.

    This Jacket Heated by Arduino #WearableWednesday



    A group of physical computing students in Italy have created a stylish jacket with heat functionality. The zipper activates a heating unit in the collar, while capacitive sensors initiate heaters in the pockets. The jacket uses an Arduino Uno and comes complete with IKEA-like instructions on the inside flap. We actually think the instructions are a nice touch as they transcend any language, making this product ready to go for international sales.

    The group cleverly named their jacket Odisseo, the Italian name for Odysseus.  Just as Odisseo is the hero of the Trojan war, this jacket is the hero of daily life. Considering the latest in temperature swings, this jacket may continue to be a hero in spring. Thinking about heating up your own wearable? You might want to look at our electric heating pad.

    Upgrading the OpenWrt-Yun image on the Yún

    ArduinoYun_orizz

    Today we released the upgraded version of the OpenWrt-Yun image on the Arduino Yún.
    This version includes all the latest and greatest from stable OpenWrt, the latest (Python) Bridge (with a php contribution and fixes to the file module), we also added Mailbox support to REST api and other fixes to some open issues.

    The new image contains also the fix to the well known Heartbleed bug, a big security issue that impacted on almost all websites of the world.

    If you own an Arduino Yún we suggest you to follow the link and read the procedure to update the board.
    You’ll need to download the zip file from the download page. Remember that updating the OpenWrt-Yun image will cause the loss of all files and configurations you previously saved on the flash memory of the Yún.
    Enjoy!

    Need An Idea For Your Next Kickstarter? Check Out This Kickstarter!

    META

    Kickstarter has become the most powerful force in kickstarting new hardware projects, video games, documentaries, and board games, and now everyone wants a piece of the action. The problem obviously isn’t product development and engineering; you can just conjure that up with a little bit of Photoshop and some good PR. The only you really need for a good Kickstarter is an idea, and META is just the tool for the job. It’s the Arduino-powered Motivational Electronic Text Adviser, the perfect device to generate the next big idea in the world of crowdfunding.

    The Arduino-powered META includes three buttons and an Arduino-controlled LCD display. Press a button, and the next big hardware project to wash across the blogs faster than the announcement of a campaign for a $300 3D printer will appear on the screen.

    Because META is Arduino-compatible, it’s compatible with existing Arduino sketches. This makes turning the META into the next home automated Bluetooth low energy 4.0 internet of things a snap. Because this is open hardware the laser cut enclosure can easily be upgraded to an RGB LED 3D printer robotic drone bluetooth boombox.

    If Kickstarters aren’t your thing, there’s also a cloud-based META that will generate ideas in the mobile app browser cloud. Bitcoin.

    I2S Audio And SPI Display With An Ethernet Module

    LCD[kgsws] is working on a small project that requires some audio and a display of some sort. While this project can be easily completed with a bigish microcontroller or ARM board, he’s taking a much simpler route: the entire project is built around a cheap router module, giving this project amazing expandability for a very meager price.

    The router module in question is the HLK-RM04 from Hi-Link, commonly found via the usual Chinese resellers for about $25. On board this module is a UART, Ethernet, and a WiFi adapter along with a few GPIO pins for interfacing with the outside world.

    [kgsws] is using the native SPI pins on this module to control the clock and data lines for the tiny LCD, with a GPIO pin toggling the chip select. I2S audio is also implemented, decoded with an 8-bit DAC, the MCP4801.

    It’s an extremely inexpensive solution for putting audio and video in a project, and since this board has Ethernet, WiFi, and a few more GPIO pins, it’s can do much more than whatever [kgsws] is planning next.

    The Faint’s new high-tech live tour features Adafruit neopixels! @thefaint #neopixels #wearablewednesday


    NewImage

    The creators project sat down with The Faint to talk about their new tour and they name dropped Adafruit!

    Can you talk about the new show, and the programming you’ve done for it?

    We’re certainly still in the middle of it. I’m using a few programs to create the content. We have lights that are programmed, many via MIDI, and that’s the way we’ve done it for ten years or so.

    We’ve got a strand of video panels straight back and scattered around the stage, and thats what I’m just starting to create content for: the videos, that will show up on the screens. They’re triggered via MIDI at this point, and we’re using a variety of programs to make that all happen.

    There’s this program called Isadora: we’ve been using it since the very first time we did projections back in 2000. The program was recommended to us by a friend, and it worked great, but didn’t have one thing we needed. We got ahold Mark, who writes the program, and he wrote a new section of the actor that we could use so the videos preloaded and would start instantly when they were hit with any note. It’s user-friendly like that; he’s helped us out every time we’ve run into an obstacle. There’s just so much you can do with video, lighting, and MIDI with that program, it’s amazing. Any time I have an idea, I seem to be able to write a program in Isadora that will do it.

    Do you have a programming background?

    Other than The Faint, no (laughs). This is all stuff that I’ve figured it out. The first time we got a Groovebox, I’d never touched anything like it. I started figuring it out, then we started running our show on an MPC. I guess I’m the kind of guy who decides to learn something he doesn’t know anything about. I always enjoy that stressful process—in the end it’s rewarding; I’ve figured something out. Once you start to understand the aspects of one programming language, the others start making more sense. I randomly dove into Isadora, bit by bit.

    One other element of the show is this clear drum set I had made by C&C, and I installed LED lights in them that are all custom programmable through this Arduino board I built. It’s a little micro-controller, so I built a little Arduino controller.

    This is my first Arduino project, using the first board I’ve bought. Basically, Adafruit sells these strips of NeoPixels with sixty LEDs per meter. They’re each individually programmable, and you have to write software in Arduino to get them up and running. I built a little box that powers them, and I can send the data and power through quarter-inch cables. I have quarter-inch jacks built into each of the drums, and so I can trigger the MIDI with drumsticks, or a sensor. As far as what the patterns do, it’s however many looks I program in the software. I’ve got some software writing to fix for sure, because I’m just guessing, and when it doesn’t work, guessing again.

    Do you find any intersections between writing code and writing music?

    They’re very different, but if I’m in the same process of writing a song or jamming out on things, I end up with parts in my head when I go out to eat. You hear little melodies and you think, ‘Oh, I should try that.’ Oddly enough, the same thing happens with writing code. If I’m in that mode, I’ll be out driving around, and my brain starts running functions to turn the turn signal on. You get sucked into both, and in that way it’s similar. But as far as actual thought processes go, it’s pretty different. I wouldn’t relate it other than that your mind gets locked into whatever creative mode when you’re doing it a lot.

    Since 1998, your growth as a band has run parallel to the dawn of all this contemporary technology. The world has changed very drastically since. I’m wondering how you guys have responded to this brave new world, and where you see it going.

    Technology has changed a bunch, which is good for us. Originally, we always had ideas for things that didn’t exist yet. Or, we’d find crappy versions of those ideas, implement them into our set, and by the end of the tour, find out about new programs that would have made things way easier. We’d been running the set on MPCs for years, and at some point I was like okay, if we switch over to a laptop it’s going to be a lot safer to go out and back it up. In a day, you could have your show ready for that night, and try out your software. An MPC is a solid machine, but if something does go wrong, it’s hard to find one that has the right amount of RAM, and all the outputs, plus they’re getting rarer and rarer…

    We had to shift, like, ‘Let’s update into the modern world for our live show so we don’t get stuck too far behind.’ I think in general, we keep up on most things. I don’t feel like I’ve really embraced the social media part of technology, but everything else I feel like I’m in tune with, as far as computers and knowing what’s up are concerned.

    Adafruit NeoPixel Digital RGB LED Weatherproof Strip 60 LED -1m: You thought it couldn’t get better than our world-famous 32-LED-per-meter Digital LED strip but we will prove you wrong! You wanted twice the LEDs? We got it (well, its 1.875 times as many but that’s within a margin of error). You wanted thinner strips? Now only 12.5 mm wide, 10 mm if you remove the strip from the casing. You wanted less noticable strip color – this strip has white-colored flex PCB, which will be less visible against white-painted walls. This is the strip with white flex PCB, its identical to the black 60 LED/meter except it has a different color mask on the flex strip Read more.

    LED Bike Helmet Gets Shouts #WearableWednesday


    LED Helmet On

    K-Fai Steele started to get concerned about riding her bike without a helmet as she heard more stories about head injuries. However, the thought of having the typical helmet just seemed like a downer. Luckily she stumbled across our LED Helmet tutorial that fit her fashion needs.

    I feel like when you put a helmet on, you lose the cool factor, but with this helmet, I get a lot of shouts from people when I’m riding.

    K-Fai is no stranger to technology, as she heads up a program with the Philadelphia Library called Maker Jawn — an initiative which is turning teens into makers at local library branches. So, needless to say, she is comfortable with a soldering iron and programming. In fact, the helmet is another example project she can show off and everyone loves LEDs. She feels the helmet, which uses a FLORA microcontroller and a NeoPixel strip,  is still a work in progress.

    I didn’t use the GPS module like in the tutorial, but I did add an accelerometer. I’m interested in finding out whether I can affect the lights with how fast I’m going.

    LED Helmet Guts

    She hasn’t done the coding yet for the accelerometer, but it is in the works. In the meantime, she is famous for being the rainbow bright rider on the streets of Philly. Our thoughts — why leave the LED fun just for the helmet?  Why not get to work on bike bling with our LED Handlebar tutorial. Biking never looked so good, and it is preventative medicine for crashes. So, light up the night.

    Electromagnetic Spiderman Webshooter Railgun / Grappling Hook

    spiderman grapple hook rail gun

    As technology continues to advance, make-believe props and technology from movies are coming closer and closer to reality. [Patrick Priebe] has managed to put together a working Spiderman Webshooter with the help of electromagnets!

    He’s built a tiny coil gun that puts out 100 Joules of energy using a 350V capacitor bank, which straps cleanly to his wrist over top of a Spiderman costume glove. It makes the classic high-pitched hum as it charges, and launches a small barbed brass arrow capable of skewering Styrofoam.

    He didn’t stop there though! He’s created a handy little winch using a small high-powered brushless motor with an ESC. A weighted disk acts as a flywheel to increase the pulling power of the fishing line, and he’s built it on a pivot so when you launch it, the fishing line just slips off the end without resistance. To engage, you flip it back perpendicular to the line and turn on the motor.

    This isn’t his first ridiculously cool gadget either — remember his 1kW Laser Pulse pistol?  Or how about the 1W Iron Man Repulsor beam?

    [Thanks Tom!]

    Bionics pioneer Hugh Herr’s prosthetic ankle mimics the power and control of its biological counterpart #WearableWednesday


    NewImage

    MIT News has a great profile on Hugh Herr and his incredible work on bionics.

    These days, Hugh Herr, an associate professor of media arts and sciences at MIT, gets about 100 emails daily from people across the world interested in his bionic limbs.

    Messages pour in from amputees seeking prostheses and from media outlets pursuing interviews. Then there are students looking to join Herr’s research group. “The technology inspires young people to get into the field, which is wonderful,” Herr says.

    It’s a mark of the groundbreaking work Herr has done at the MIT Media Lab over the past two decades. An amputee himself, Herr has been designing (and wearing) bionic leg prostheses that, he says, “emulate nature” — mimicking the functions and power of biological knees, ankles, and calves.

    Last month, Herr’s TED talk made headlines, as Adrianne Haslet-Davis, a professional dancer whose leg was partially amputated after the 2013 Boston Marathon bombings, used one of his prostheses to rumba on stage.

    Most of these prostheses have reached the world through Herr’s startup, BiOM (originally called iWalk). Since 2010, the company has brought the world’s first bionic foot-and-calf system to more than 900 patients worldwide, including some 400 war veterans.

    “It’s always good to design something people will use. It’s great to do the science, yes, but it’s also great to see humanity using something that one has invented,” Herr says, adding: “Translating technology out of the lab keeps engineers honest.”

    NewImage

    Initially developed by Herr’s research group, BiOM’s prosthesis, dubbed the BiOM T2 System, simulates a biological ankle (and connected calf muscle), delivering a “natural ankle function” during strides.

    Using battery-powered “bionic propulsion,” two microprocessors and six environmental sensors adjust ankle stiffness, power, position, and damping thousands of times per second, at two major positions: First, at heel strike, the system controls the ankle’s stiffness to absorb shock and thrust the tibia forward. Then, algorithms generate fluctuating power, depending on terrain, to propel a wearer up and forward.

    When fitting the prosthesis to patients, prosthetists can program appropriate stiffness and power throughout all the stages of a gait, using software created by Herr’s group — a process the company calls “Personal Bionic Tuning.”

    Among other things, the system restores natural gait, balance, and speed; lowers joint stress; and drastically lowers the time required to acclimate to the prosthesis (which can take weeks or months with conventional models). “Often, within minutes, a patient is walking around, even running around,” says Herr, BiOM’s chief technology officer.

    The system, Herr says, could also help prevent osteoarthritis, a joint condition caused by age and leg strain, by providing calf and ankle power and support even in old age.

    HummingBoard, The Vastly More Powerful Raspi

     

    Humming

    The Raspberry Pi has been around for a while now, and while many boards that hope to take the Pi’s place at the top of the single board ARM Linux food chain, not one has yet succeeded. Finally, there may be a true contender to the throne. It’s called the HummingBoard, and packs a surprising amount of power and connectivity into the same size and shape as the venerable Raspberry Pi.

    The HummingBoard uses a Freescale i.MX6 quad core processor running at 1GHz with a Vivante GC2000 GPU. There’s 2GB of RAM, microSD card slot, mSATA connector, Gigabit Ethernet, a BCM4329 WiFi and Bluetooth module, a real-time clock, and IR receiver. There’s also all the usual Raspberry Pi flair, with a 26 pin GPIO connector, CSI camera connector, DSI LCD connector,  stereo out, as well as the usual HDMI and analog video.

    The company behind the HummingBoard, SolidRun, hasn’t put a retail price on the board, nor have they set a launch date. You can, however, enter a contest to win a HummingBoard with the deadline this Friday. Winners will be announced in early May, so maybe the HummingBoard will be officially launched sometime around then.

    It’s an amazing board with more than enough power to rival the extremely powerful BeagleBone Black, with the added bonus of being compatible with so many of those Raspberry Pi accessories we all love dearly.
