Woven's wearable platform for gaming, cool points and a whole lot more (video)
TshirtOS showed us one take on wearable gadgetry earlier this month, and now it's Woven's turn. This particular e-garment packs quite the selection of hardware, as you can see above -- a trio of LilyPad Arduino boards (and some custom ones), a Bluetooth module, 12 x 12 RGB LED "screen", speakers, bend sensors, a heart rate monitor, shake motors and a power pack. You'll need to accessorize, of course, with a smartphone for hardware harmony and to run companion apps. So what's it for, you ask? Well, the creators are touting it primarily as a "pervasive" gaming platform, and even seem to have a working first title in the form of SPOOKY (think gesture-based ghost-fighting). Other uses (which appear a little more conceptual) see Woven as a workout companion, TV remote, Wii controller, social network alerter or simply a fashion accessory. Check out the videos below to see it in action and imagine all the fun you could have in the five minutes before you're ushered into that padded room.
Personal Energy Orb Arduino project knows you haven't been exercising, cripples your computer
Spending too much time indoors? You need a Personal Energy Orb, a glowing Arduino powered ball that allows you to trade physical exertion for a tolerable mouse speed. Developed by two students at the University of Munich for a physical computing course, the PEO connects to a bike-mounted revolution counter to note how far a user rides, counting the total distance toward usable time on a computer. A fully "charged" green orb will allow a user to use their PC unhindered -- but a spent red orb will drag Windows' cursor sensitivity settings to its lowest. The idea, the project's creators say, is to annoy the user off of the computer and back on to their bike. It sure sounds aggravating to us. Check out the full homework assignment at the source link below, complete with goals, follies and Python scripts.
Arduino GSM/GPRS Shield gets helping hand from Telefonica for data, remote control
Arduino devices have had the option of a GSM linkup for awhile, but getting that cellular link to truly strut its stuff hasn't always been easy, even for those of us who'd be inclined to program an Arduino in the first place. Enter Telefonica, which wants to be the backbone of your internet of things. It's backing a new version of the GSM/GPRS Shield add-on (shown here) by offering both the expected machine-to-machine SIMs for the cellular connection as well as freshly added remote control of the board through the carrier's BlueVia pages. The Shield itself is getting a quiet upgrade in the process -- the software both takes up a smaller footprint and can now talk to the world in the background while the Arduino keeps on keepin' on. If you happen to be in Berlin, the new Shield is making the rounds at Campus Party workshops until April 25th. Neither side has said how readily available the new part will be available after that; for now, you can familiarize yourself with the current technology at the source link.
Liquidware team crafts laser tripwire that tweets intruder alerts, keeps fake sharks at bay (video)
Laser tripwire security systems can be expensive propositions that don't always work as planned -- just ask Raytheon, which saw its $100 million Perimeter Intrusion Detection System for JFK International Airport undermined by one wayward jet skier. Taking that as a form of dare, Justin Huynh and teammates at Liquidware have devised a much cheaper (if also much smaller) tripwire of their own. Any interruption of a laser pointer's beam is caught by an Arduino light sensor that promptly sends the alert to an Android-running BeagleBoard xM; if a toy like Bruce the shark dares cross the line, the BeagleBoard sends a Twitter message to let the authorities, or at least Huynh, clamp down on the trespasser. The invention won't replace Raytheon's handiwork anytime soon, although Huynh notes that additional or more powerful sensors could theoretically catch real, muscle-bound sharks and not just their plastic counterparts. The supply checklist and source code are waiting on the company's project page below, so those who'd like to ward off miniature invasions can get started today.
Digispark, Arduino's unofficial kid brother, takes Kickstarter by storm (video)
Hobbyist Erik Kettenburg was concerned that the size and cost of Arduino stifled his ability to craft, so he set about developing Digispark. It's an Arduino-compatible board, the size of a quarter, that offers a few pins at around a third of the cost of an Uno -- so you don't have to worry about taking projects apart when you're done. Designed to be fully compatible with the Italian standard, it's packing six I/O pins, 8k memory and a full USB connection amongst other things. The aim is to retail the gear for $12 a piece, and has been so popular that it's made nearly $100,000 in Kickstarter pledges, smashing its original goal of $5,000. We've got video for you below, and you can still throw some cash Mr. Kettenburg's way if you fancy getting your hands on one quickly.
Bioshock custom rig is Big Daddy of pinball machines, gives players a taste of Rapture
If you're going to revisit a certain underwater dystopia, you might as well have a ball. At least that's the approach being taken by Sweden-based DIYer rasmadrak, who has decided to build a Bioshock-themed custom pinball machine just for kicks. The project is filled with lots of neat little touches from Rapture, including Little Sister vents and a few Big Daddy homages. The builder also does a pretty good job of drilling into the details and providing insight on the creation process -- like the challenge in using two different systems such as Arduino and chipKIT together, for example -- via detailed posts in the Poor Man's Pinball! blog. The project proved to be a pleasant shock to the system for fellow pinball aficionado Ben Heck, who gave the project a sprinkling of Heckendorn love via Twitter. Pinball geeks can also follow the saga, so to speak, by checking out the source link below.
Check 'N Chew Foursquare-enabled gumball machine hands-on (video)
When Tyler DeAngelo asked if we'd be interested in checking out his new project, we jumped at the opportunity. After all, we were pretty blown away with Fifth Avenue Frogger, his hacked arcade cabinet that incorporated real-time webcam footage of a busy Manhattan street into gameplay. His latest project, Check 'N Chew certainly has more apparent commercial applications, offering up a form of immediate gratification for social media users. The concept is fairly simple: check into Foursquare, get a gumball. DeAngelo (with help from fellow modders Matt Richardson and Ben Light) has hacked an off-the-shelf gumball machine with a stepper motor, Arduino and an XBee radio. There's also a port on the rear of the machine that plugs into a wall to power it all. The Check 'N Chew communicates wirelessly with an ethernet-to-wireless gateway device. When someone checks into an authorized location, information is sent from DeAngelo's server to the gateway, and a gumball is dispensed. The whole process is quite speedy, only taking a couple of seconds from Foursquare check-in to gumball dispensing.%Gallery-162652%
Arduino-based SocialChatter reads your Twitter feeds so you don't have to (video)
If you prefer reading your RSS feeds without the backlight, there's hardware for that, and if you'd prefer not reading your Twitter feeds at all, there's now hardware for that as well. Mix an Arduino Ethernet board, an Emic 2 Text-To-Speech Module and the knowhow to put them together, and you've got SocialChatter -- a neat little build that'll read your feeds aloud. The coding's already been done for you, and it's based on Adafruit's own Internet of Things printer sketch with a little bit of tinkering so nothing's lost in translation. If your eyes need a Twitter break and you've got the skills and kit to make it happen, head over to the source link for a how-to guide. Don't fill the requirements? Then jump past the break to hear SocialChatter's soothing voice without all the effort.
Raspberry Pi teases finished Gertboard I/O extender, revs creative engines (Update: pre-orders open now, video)
The Raspberry Pi faithful have been looking forward to the Gertboard almost as much as the main device itself: Gert van Loo's I/O extender promises to flash lights, spin motors and otherwise take on the tasks that the Raspberry Pi doesn't directly manage on its own. While we've seen work on the project since late 2011, the expansion now looks to be closer to reality following a fresh teaser. The refined design's biggest tweak is replacing its original PIC controller with an Arduino-powered chip -- an element no doubt familiar to the crowd that would already be looking at a very hackable, miniature Linux computer. Most everything else is a refinement, although Gert has brought in three physical buttons and two-channel analog-to-digital and digital-to-analog converters. We'll learn the full story later this week, and until then we'll be dreaming of all the off-kilter Arduino projects that might be made better with a little Raspberry Pi companionship. Update: The wait turned out to be short, and interested parties ready to do some soldering of their own can pre-order the Gertboard for £30 at element14 now. Check the Raspberry Pi blog (2) for more info, or check out a video interview with Mr. van Loo himself embedded after the break.
Super Angry Birds USB controller puts the sling back in your shot (video)
Yeah. We know. There are pretty much as many ways to play Angry Birds, as there are people who play it. That's a lot. However, the Super Angry Birds controller you see above speaks to us. Why? Because it's not just a sling shot, or a fudged use of existing technology. That wooden "sling" hides one of those motorized faders you see in big music studio desks. Using some coding magic (i.e. a force curve stored in a table), the creators were able to give it a realistic resistance feeling, sans elastic. The rest of the hardware is programmed in Max / MSP and Arduino, with a "Music and Motors" microcontroller. It's not just the sling part, either, with angle and special power triggering available from the same device. A pretty neat solution, we think. Now, we wonder if we could scale this thing up?
Hacker finds flaw in hotel locks, can ruin your vacation with $50 DIY gadget
Admittedly, the headline is designed to get your dander up. You're in no immediate danger of a technologically-gifted thief plugging a couple of wires into your hotel door and making off with your sack of souvenirs from the Mall of America. But that's not to say it's impossible. Cody Brocious, who was recently brought on by Mozilla to work on Boot to Gecko, is giving a presentation at the annual Black Hat conference in Vegas where he demonstrates a method for cracking open keycard locks with a homemade $50 device. The hack only works on locks made by Onity at the moment, and real life testing with a reporter from Forbes only succeeded in opening one of three hotel doors. Still, with between four and five million Onity locks installed across the country (according to the company), that is a lot of vulnerable rooms. The attack is possible thanks to a DC jack on the underside of the lock that's used to reprogram the doors. This provides direct access to the lock's memory, which is also home to the numeric key required to release the latch -- a key that is protected by what Brocious described as "weak encryption." Ultimately the source code and design for the Arduino-based unlocker will be published online alongside a research paper explaining how these locks work and why they're inherently insecure. The hope is that manufacturers will take notice and improve the security of their wares before the world's ne'er-do-wells perfect Brocious' technique.
Arduino Leonardo finally launches with new pin layout, lower price (video)
We caught our first glimpse at the new, simplified Arduino Leonardo at Maker Faire back in September of last year. At the time, we were promised a late October shipping date, but it failed to materialize. Finally, Massimo Banzi has taken the wraps off the slimmed down microcontroller and its now in stock at retailers across the web. The Leonardo sports a new pin layout, dubbed R3 (which the Uno has also been updated with), that will become standard across all Arduino boards. That's a big deal for shield makers who only have to design and manufacture an add-on once to ensure it's compatible with the entire product line. The new layout also adds some extra pins and versatility, especially in the realm of shields, which can use to the new IOREF pin to determine the voltage of the processor and thus its model. That means a shield doesn't have to be designed specifically with the new ARM-based Due in mind. The other big news is that the circuitry for converting USB to serial communication and the processor itself have been combined, which not only simplifies the design and drives down costs, but allows it to communicate directly with a computer and imitate all sorts of accessories (such as keyboards and mice). Best of all, is the price. The Leonardo, complete with headers, costs just $25 -- a good $10 less than the Uno -- while the headerless, solder-friendly version retails for $22.50. Check out the video after the break for a few more details from Massimo himself.
Arduino Kegerator hack checks in your homebrews on Untappd
Quite possibly the two greatest things in the world -- beer and Arduino -- have been married once again in a hack does them both justice. Accomplished maker and alcohol enthusiast Jeff Karpinski turned a spare Uno and an Ethernet shield into a gadget that automatically checks him in on Untappd. The build is connected to his kegerator through a hall-effect flow sensor that sits in his tap lines. Every time he pulls himself a pint of homebrew, the Aruino makes an API call to the so-called Foursquare for beer nerds, and updates his profile. Obviously, publishing to the site every time the keg is tapped could get messy, so there's an automatic five minute time out to avoid getting repeat hits just for topping off. There's also a button that manually engages the five minute lock out, allowing Jeff to pour his buddies a cold one without claiming the drink for himself on Untappd. And updating is a snap thanks to the simple web server that's integrated. Changing what beer is on tap in the API call is as simple as opening a web browser. Interested in upgrading your own kegerator? Check out the source link for complete instructions and a parts list.
Bad Posture tells you to sit up straight, replaces your mom with an Arduino
At certain point in every geek's life, their mother gives up and stops yelling at them to sit up straight. If the lack of constant reminders to maintain good posture has you slouching and hunching, there are countless technological substitutes. Even a few nice DIY ones. But we've got to give Ellen Sundh props for the simplicity of her solution. While similar projects rely on accelerometers, which can be difficult for the budding hobbyist to work with, to monitor the angle of your body, Bad Posture sticks with a simple bend sensor to keep tabs on your spinal cord. The flexible plastic is arranged vertically in a fabric belt that also houses an Arduino, a Wave Shield from Adafruit and a push button for calibration. Sit at your optimal angle, press the button and you're ready to go. Bend too much and the Wave Shield plays a warning -- "bad posture!" Check out the video after the break to see it in action.
OLED Lego train station emerges from Adafruit and Arduino gear, minifigs to get home on time
Who knew Lego characters had to be somewhere in a hurry? Adafruit did, as it just whipped up a minifig-sized train schedule. The invention mates one of Adafruit's own 1-inch OLED boards with an Arduino Uno controlling the schedule behind the scenes. It looks to be a straightforward project for the DIY types, although the display is currently all show: the schedule doesn't (yet) pair up with the train tracks to automatically let your minifigs know if their trip to the pirate spaceship castle has been delayed by ghosts. You can check the source link for the full instructions. Duplo builders, alas, are kept out of the loop.
Crayolascope hacks toys into foot-thick 3D display
Artist Blair Neal, as many other great creators have before him, turned to children's toys as the source of inspiration for his latest project. Crayolascope is a rudimentary 3D display hacked together from several Glow Books, a light-up play on a flip-book from the titular company. The installation, currently housed at the New York Hall of Science in Flushing, layers 12 of its component clear plastic sheets to create a roughly one-foot deep display that plays a simple pre-drawn animation. The whole thing is controlled by an Arduino Mega, that can either play back the neon scribbles at varying speeds (controlled by a knob built into the console) or scrub through frame by frame. Neal isn't quite done tweaking the Crayolascope either. As it stands he's limited to between 14 and 18 frames, before it becomes too difficult to see through the sheets. And it requires near total darkness for optimal operation. To see it in action check out the video after the break.
Sassor wants to let users know just how much electricity their gadgets are wasting (hands-on)
Everyone knows that their game consoles, appliances and HDTVs are energy vampires, and while Energy Star-certified products tell us which gadgets are more green-friendly than others, we still don't know just how much juice they're actually sucking down in a given day. Enter Sassor, a start-up from Japan that's created a system to monitor the electrical consumption of anything plugged into a wall outlet -- from PCs to refrigerators. It tracks power consumption using current sensors clamped onto power cords, which communicate wirelessly via ZigBee with a module (based on an Arduino design) that uploads the info to the cloud. Through the web portal, users can track energy consumption on a per-device basis in real-time, letting them figure out which gadgets are most responsible for their sky-high utility bill -- and take appropriate steps to correct the problem. Currently, it's aimed solely at businesses, but once Sassor's on its feet, funding-wise, the plan is to also put them in people's homes. The company told us it'll ditch ZigBee in favor of a WiFi solution in such future iterations, and it'll make an SDK and the system APIs available to all so that people can program for the platform and improve it in ways currently not contemplated. Alas, there's neither a timetable nor a price for the consumer version just yet, but you can see some pictures of the hardware's innards below.
ArduSat wants to put Arduino satellite, your experiments into orbit
Short of scoring a spot on the ISS experiment docket, putting your scientific aspirations into orbit can be a bit tricky. Why not try crowdsourcing your way into space? ArduSat's barking up that very tree, asking Kickstarter contributors to help them get a Arduino CubeSat off the ground. Headed by NanoSatisfi, a tech startup operating out of NASA's Ames Research Center, the project hopes to raise enough funds to launch an Arduino bank and a bevy of open-source sensors into orbit. The payoff for backers? Access. Varying levels of contribution are rewarded with personalized space broadcasts, remote access to the space hardware's onboard cameras and even use of the machine's sensors to run experiments of the backer's own design. If all goes well, the team hopes to launch more satellites for the everyman, including a unit dedicated to letting would-be stellar photographers take celestial snapshots. Sure, it's far cry from actually launching yourself into the stars, but would you rather be a tourist, or a scientist? Check out project at the source link below, and mull over that for awhile.
Hexy: hands-on with the adorable, affordable hexapod (video)
The Artisan's Asylum has a few guiding principles, one of which is anyone can "make." We assume one of the others is "you can never have too many hexapods." If Stompy, the giant rideable bot, is a bit much for you to handle (or store), then maybe Hexy is more your speed. He's got six legs and 20 servos, but at only $200, he's much cheaper than similar hexapod kits and, most importantly, more adorable. The bot is the brain child of Joseph Schlesinger, a resident at the Somerville hacker space who saw a need for a low-cost but serious robotics kit. Since hitting Kickstarter in May, his creation has raked in roughly $86,000 in pledges, far surpassing his original goal of thirteen grand. We swung by Joe's booth to get a taste of what exactly his hundreds of backers have bought into and to find out what's next for the budding bot entrepreneur.
Rascal Micro hands-on (video)
Not far from the bustling labs of Northeastern University is the even more bustling hacker space known as Artisan's Asylum. The roughly 30,000 square foot complex is home to more than 100 makers, tinkerers and artists who building all sorts of crazy contraptions. One of the less ostentatious projects being worked on within its cavernous halls though, is the Rascal Micro. This tiny board is home to an ARM-based SOC and has its hungry, open-sourced eyes on competitors like Arduino and Beagle. Brandon Stafford, the creator, boiled down its primary selling points to this: "it's maybe 25 times faster, has 1,000 times more storage." Where as the Arduino excels at making things blink, move or Tweet, the Rascal Micro has enough power to function as a full-fledged web server. %Gallery-158223%
