Insert Coin: Modkit Micro asks us if we're ready for six-year-olds coding Arduino boards
In Insert Coin, we look at an exciting new tech project that requires funding before it can hit production. If you'd like to pitch a project, please send us a tip with "Insert Coin" as the subject line. What does microcontroller programming have in common with Tetris? Quite a bit if you're doing it with Modkit Micro from a Kickstarter project out of Cambridge, MA., which allows almost anyone to visually set up their hardware using graphical blocks to write the code. The partially-hooded trio behind it promises that the software is ideal for use with prototyping boards from Arduino, Evil Mad Science, Lilypad, Seeed Studio, Wiring and SparkFun, and they even claim that elementary school students have used it to "take their projects from concept to reality in just a few hours." Purists should have no fear either: you can still get into a code view to see what's going on behind the scenes. A web-based Modkit Micro is being offered online starting June 1st for $25, and there'll be a desktop variant for Windows, OSX, and Linux as early as July if they reach their funding target. Check out the video after the break and then try to get your kids to wait for college before inventing version 2.0 of this.
Panasonic preps samples of next-gen ReRAM devices, NAND preps for early retirement
The Galaxy S III may rock an impressive battery life, but if Panasonic has its way, even greater benchmarks could be on the horizon. The company is ready to start making samples of a new ReRAM microcontroller, and -- like Sharp and Elpida -- it could start mass production as soon as next year. Here's a little refresher: ReRAM is a new kind of memory with re-write speeds far superior to NAND because it doesn't need power to hold onto information. Panny's chip will initially be used in simple devices like fire alarms, but the tech could eventually find its way into our TVs and even smartphones and tablets. But seriously, are we even capable of living in a NAND-free world?
KegDroid dispenses beer with the help of a Xoom tablet and an Arduino board
Here's an instance of NFC technology that's more exciting than yet another tap-to-pay scenario. Google employee Paul Carff combined a Motorola Xoom running ICS with an Arduino microcontroller to create KegDroid, a friendly green beer dispenser. The Xoom acts as a gatekeeper to that brewed goodness, only letting the bot dispense drinks after users swipe an authorized badge. The badge is read by an NFC scanner on the bottom of the case and is then authenticated (or rejected) by the Arduino board. Once the system grants access, users can choose from two selections on tap via a custom Android application displayed on the Xoom's screen. As Android Community points out -- and as you'll see in the video below -- the KegDroid hasn't mastered a bartender-level pour (read: there's way too much foam). Still, this is oodles cooler than your average keg, wouldn't you agree?
ARM Cortex-M0+ is a low-power, low cost 32-bit processor for the 'internet of things'
The "internet of things" is quite the buzzed about phenomena these days and everyone wants in on the action. But, much of the hype so far has been associated with that DIY staple, the Arduino, and its admittedly under-powered 8-bit MCU. ARM is looking to put more power at developers fingertips, though, with the Cortex-M0+, an ultra low-power processor designed for embedded applications. The 32-bit chip is based on the existing M0, but with significant tweaks that greatly improve performance while keeping power draw to a minimum. Freescale and NXP should be first out the box with licensed processors and, while we wouldn't anticipate these showing up in a refrigerator or printer just yet, we wouldn't be shocked if they drew some interest from hobbyists. Check out the complete PR after the break.
Pinoky makes it easier to pretend like your stuffed animals are real friends (video)
Seated above, from left to right, are Ms. Snuggleberry, Mr. Cuddlekins, and Professor Puddles. They congregated atop this egg yolk for what they thought would be another customary meeting of Mammalian Malice -- a vaguely neo-Jacobean slam poetry collective founded in the aftermath of the Crimean War. Little did they know, however, that they were walking straight into Yuta Sugiura's trap. Sugiura and his colleagues, you see, have created a toy known as Pinoky -- a small, ring-like device that wirelessly brings stuffed animals to "life," as Snuggleberry, Cuddlekins and Puddles soon discovered. Developed as part of a project at Keio University, Pinoky uses a micro controller, a Zigbee input device and a servo motor system to move an animal's extremities, with a set of photo sensors designed to measure the angle at which it bends. All you have to do is grab your favorite imaginary friend, strap a Pinoky around his limb, and use the accompanying remote controller to make him flail around like a fish on house arrest. See it for yourself, after the break.
Add lasers to a tennis ball, drive your dog crazy (video)
It's a "programmable disco ball," a "cat toy for humans," and a "personal laser light show," all rolled into one. That's how one Matt Leone describes his latest creation, aptly known as the Laser Ball. To realize his dream, Leone drilled a set of holes into a garden variety tennis ball, and inserted about 14 laser diodes, each with an attached strip of diffraction grating. Said diodes were then synced up with an Arduino-equipped Teensy microcontroller nestled within the ball, alongside a rechargeable battery. As a cherry on top of this DIY sundae, Leone then incorporated an infrared remote package from Adafruit, allowing him to remotely jump start his next house party. The result is a cyborg-like ball that makes any LED cube look... square. Check it out for yourself, in the video after the break.
Broadcom's got a WICED game it plays, to make smart devices feel this way
Broadcom wants you to fall in love with its BCM 4319 WICED (Wireless Internet Connectivity for Embedded Devices) platform -- a weeny 802.11 a/b/g /n WiFI module that can be added to any device that uses a microcontroller. Jimmy one into your fridge, digital camera or aircon and it'll find its own way to the cloud. With instant networking for kit like this, doctors could monitor patients vital signs, your holiday snaps could find their own way online and, most importantly of all, you can make sure the kids aren't fiddling with the darn thermostat again.
Virtual MIDI piano glove even makes MJ's sparkly one look tame (video)
When a piano necktie or keytar just feel too showy, why not opt for the more subdued wireless MIDI piano glove? An excellent choice for daytime or night, the hand accessory allows you to tickle the virtual ivories without putting a finger to a real eighty-eight. It works as such: wired with resistive flex sensors, move a finger and the glove will send an electrical current through a voltage divider and microcontroller to create the corresponding MIDI note. The result? Single notes or chords of musical greatness truly worthy of a bad karaoke singalong. Check out the MIDI throwback video after the break.
Insert Coin: BoardX is an open-source, modular motherboard for prolific prototypers
In Insert Coin, we look at an exciting new tech project that requires funding before it can hit production. If you'd like to pitch a project, please send us a tip with "Insert Coin" as the subject line. We're more than a little enamored with Arduino and its DIY microcontroller ilk. But we'll admit, there are a few limitations that the compulsive prototyper might find bothersome. Chief amongst them is the lack of modularity, Now, sure, you can easily add all sorts of sensors, ports and radios to your Uno (or Duemilanove if you're old school) but that generally requires piling shield, upon shield, upon shield, until you've got a stack of boards three-feet high. And, if you want to use an ARM chip instead of an AVR for a project? Well that's a whole other set of boards. Kevin Greene has decided to address these perceived "weaknesses" with BoardX -- a modular, open-source prototyping platform.
Freescale joins ARM A5 and M4 cores at the hip for performance and power savings
You may have noticed a trend recently -- pairing slightly less powerful cores that sip power, with more robust ones that can chug through demanding applications. NVIDIA's Tegra 3 will be packing an underclocked fifth core, while ARM's big.LITTLE initiative matches a highly efficient 28nm A7 with the beefy A15. Now Freescale is planning to use the same trick, but you won't find its asymmetrical CPUs in your next tablet or smartphone. Its platform, which marries a Cortex M4 to a Cortex A5, isn't meant to compete with the latest Snapdragon. These chips will find homes in factories and in-dash infotainment systems which have increasingly sophisticated UIs, but don't need to push thousands of polygons. Software development tools will land before this quarter is out and the first batch of silicon will be announced in Q1 of 2012. Looks like the era of "dual-core" meaning two identical cores has officially come to an end.
Arduino-powered lighting system infuses your LED with some Ambilight-like pizazz (video)
Why spend your hard-earned money on one of Philips' Ambilight displays when you can just make your own, using some Arduino-based wizardry and a little bit of elbow grease? Fortunately, Minty Boost creator ladyada is here to help. All you'll need is a strand of digital RGB LED pixels, a five-volt DC power supply (along with a female power adapter), any USB-equipped Arduino micro-controller and, of course, the appropriate Processing programming environment. You can find the full how-to at the source link below, but the results are pretty impressive -- a capture-based sketch system that's compatible with just about any media player. See it for yourself in the video after the break. [Thanks, Phil]
Tacit sonar gauntlet gives the blind ultrasonic eyes (video)
Sure, your Arduino project can make a stuffed monkey dance, but is it really doing anything for the greater benefit of mankind? Okay, maybe -- but not to the same degree as Grathio Labs' Tacit glove, an Arduino powered sonar device that can help the vision impaired navigate foreign environments. This wrist-mounted gauntlet is comprised of an Arduino microcontroller, a few ultrasonic sensors, and a pair of servomotors to apply variable pressure to the user's wrist to indicate their distance from an object or obstacle. Best of all, the gizmo's circuit and software are registered under Creative Commons, which means you're free to snag the plans from the source link below, and build your own. Go on, build one. Sure, it's a lot of work, but would you rather rock a wrist-mounted sonar gun, or don an ear-tugging bicycle helmet? Your choice.
Kinect / Arduino hack makes stuffed monkey dance for your amusement
Just when you thought that people had squeezed the last drop of creativity out of Microsoft's Kinect, something like this comes along. It's a stuffed monkey with a robotic skeleton that can mimic the movements of the person standing in front of it. "Monkey Business" is an art installation of sorts created by Jan M. Sieber and Ralph Kistler. It uses a camera sensor from a Kinect, an Arduino mircocontroller, and 10 servomotors. The smirking robo-monkey, meanwhile, is suspended from the wall, giving it a full range of movement. The resulting video is pretty darn delightful.
LED coffee table busts a multicolored move (video)
It might look like something out of MJ's Billie Jean, but this colorful LED array won't be under moonwalking foot -- that is, unless the party gets crunk. This colorful grid is actually a table top, brought to you by way of TI's MSP430 microcontroller, and it knows how to get down. The table is made up of 128 frosted glass cubes, each apparently capable of emitting 16 million colors. Its creators also produced a special beat-detection software, that could very easily have your furniture outshining the bumpers and grinders at your next party. If you're looking for a little extra something from your coffee table, you can find full build instructions at the source link below.
Simple DIY cellbot ditches Arduino, jousts poorly (video)
Want an adorable little Android cellbot to call your own, but aren't quite ready to tackle Arduino code? Darrell Taylor's got you covered with an audio-controlled, jousting cellbot: no muss, no fuss, no microcontroller. The Make project, called TRRSTAN, accepts commands via Google chat, web browser, or Wii remote piped through the headphone jack of your Android phone -- the robot's brain, of course. Tack on a few makeshift weapons procured at the local dollar store, and you've got a homemade warrior you can be proud of. Want one? Taylor has a ready-made kit available for just shy of $50, and offers a 'fully assembled' option for the extra-lazy robot enthusiast. Of course, you could always go back to playing Android-bots with your Legos if you aren't quite ready to big-boy world of DIY. Just sayin'.
Modder miniaturizes 5.25-inch disk drive, brings microSD support to Atari 400
You aren't looking at a retro microSD card reader, you're looking at an Atari-compatible serial disk drive that just happens to use microSD in lieu of 5.25-inch floppies. In a Zork inspired fit of nostalgia (we've all been there), hardware modder Rossum paired up an Atari connector with a LPC1114 microcontroller, capable of emulating up to eight Atari drives, managed by a custom, auto-booting app. The whole package is neatly packed in to a tiny 3D printed replica of the original Atari 810 disk drive, and is available for sale never -- but don't let that stop you: Rossum's schematics are free for the taking. The word's biggest little Atari drive is just a DIY away. [Thanks, Francesco F.]
Netduino Plus earns you Ethernet and microSD, an approving nod from Microsoft
The two new Arduinos should spell good things for the Arduino heads out there, but meanwhile, on the other side of the tracks... Secret Labs is launching its .NET-friendly Netduino Plus, which adds Ethernet and microSD to a regular Netduino board (which in itself is a sort of high powered, Visual Studio-compatible Arduino, with a 32-bit 48MHz ARM7 processor, instead of Arduino's 8-bit number, but pin compatible with Arduino "shields"). Unfortunately, the networking code eats of a good majority of the board's already meager code storage and RAM, but you can always flash the original Netduino's firmware on here if you'd like. Right now the board is in a "public beta" while the firmware gets some extra tweaks, but you should be able to drop $60 on the final model by the holidays. %Gallery-103288%
Arduino Uno and Arduino Mega 2560 get friendly new USB plugs, new look
Arduino is so much about what is made with Arduino boards that we hardly spare a thought for the boards themselves. Well, Arduino cares, and they've just gone about redesigning their base model, now dubbed the Arduino Uno. It's of course backwards compatible with existing Arduino add-ons, but sets itself apart with a new USB controller with lower latency and driver-free operation on Mac and Linux. This should make Arduino slightly more friendly to the super novices, but of course the USB chip can be reprogrammed by the experts to be all sorts of things. Meanwhile, the Arduino Mega is getting the same USB chip along with an ATMega2560 processor with twice the memory. Right now only 128K is available, but that's a software limitation and they're working to unlock the rest of the memory space. The Mega sells for $65, while the Uno goes for $35. Next up? An Arduino board with built-in Ethernet and microSD. Crazy, we know. %Gallery-103287%
The multimeter clock doesn't fail to electrify us
This is the multimeter clock. It's made of three actual multimeters -- one each to display the hour, minutes and seconds with a 16F628A PIC microcontroller to do the actual timekeeping. Do we want one hanging in our living room? Not really: but it's still very cool.
Students program Human Tetris into 8-bit microcontroller, give away schematics for free (video)
Sure, Project Natal is the hotness and a little bird tells us PlayStation Move is pretty bodacious, but you don't have to buy a fancy game console to sooth your motion-tracking blues. When students at Cornell University wanted to play Human Tetris (and ace a final project to boot), they taught a 20Mhz, 8-bit microcontroller how to follow their moves. Combined with an NTSC camera, the resulting system can display a 39 x 60 pixel space at 24 frames per second, apparently enough to slot your body into some grooves -- and as you'll see in videos after the break, it plays a mean game of Breakout, too. Full codebase and plans to build your own at the source link. Eat your heart out, geeks.
