Raspberry Pi Pico is a $4 Arduino alternative
The Raspberry Pi team has released the Pico, a $4 microcontroller that competes with Arduino.
Freescale makes the world's smallest ARM controller chip even tinier
Apparently, Freescale didn't think the diminutive Kinetis KL02 was tiny enough -- it just unveiled the KL03, the new world's smallest ARM microcontroller. At 1.6mm by 2mm, the Cortex-M0+ chip is 15 percent smaller than its ancestor. That's miniscule enough to comfortably fit inside the dimple of a golf ball, folks. Despite the shrunken profile, it's both easier to program and more energy-efficient. The size isn't just for bragging rights, of course. Freescale sees the KL03 helping out the internet of things, where a fraction of a millimeter can make a big difference. Companies can't start using the chip in earnest until it enters full production this June, but it may lead to very compact smart appliances and wearables once it arrives.
Hands-on with BITalino, a microcontroller board for quirky and serious projects alike (video)
It's safe to say that BITalino isn't your average DIY electronics board. For starters, the sensors that spring from the main unit (which comprises the microcontroller, Bluetooth module and power unit) are more at home in a hospital than they are scattered over a tinkerer's workstation. Jutting off the main board are a light meter, accelerometer, heart-rate sensor (ECG), muscle activity sensor (EMG) and a sensor to measure sympathetic nervous system activity (EDG). There's also a standard LED, and while all the above forms a single structure, each module can be snapped off to mix and match for specific projects. BITalino is a semi-finalist in our Insert Coin competition being held at Expand NY this weekend, but before that kicks off, we caught up with its creator Hugo Silva to talk about the board's inception, applications and what lies in its future.
Insert Coin semifinalist: BITalino is a self-contained physiological tinker lab
You might be asking yourself, do we really need another electronics tinkertoy / microcontroller kit? And we say, you can never have too much of a good thing. BITalino takes the standard setup, and includes all the sensors you could want to get started building your next DIY project. There's a light sensor, an accelerometer, as well as sensors for electromyography, electrocardiography and electrodermal activity. All that data can then be fed to a host machine over Bluetooth. It even comes in a variety of forms: one where the sensors can be unplugged and rearranged, one where the components sit on perforated boards that can be snapped off should you want to position the sensors away from the main board and one where the company has already disassembled the various components for you. You can see all of the Insert Coin semifinalists here.
Olympia Circuits' Arno Shield lets Arduino newcomers bring their own board
While there have certainly been attempts at easing the Arduino learning curve, many of these still demand a new board or simplify just one aspect of a much larger universe. Olympia Circuits' new Arno Shield could help strike a better balance between starting fresh and diving into the deep end. It includes all the buttons, lights and sensors needed for 40-plus educational projects, but grafts on to existing boards such as the company's LeOlympia or an Arduino Uno. Owners don't have to add parts or wires; they just remove the shield once they've learned enough to create their own masterworks. The shield kit won't be cheap when it arrives on May 2nd for $60, but it may prove the real bargain for tinkerers who want a full-fledged Arduino board as soon as the training wheels come off.
Pebble 1.9.1 firmware update arrives to resolve shutdown woes
Some Pebble owners were understandably perturbed when their smartwatches seemingly went dead after a shutdown -- that's not the best first impression of an emerging technology. Some credit is due for a rapid turnaround, however, as the Pebble team just delivered a 1.9.1 firmware upgrade that should tackle the problem. It fixes a bug that occasionally prevented the microcontroller from reconfiguring itself before the watch went dark, leaving the buttons unresponsive on wake and the Pebble more of a paperweight. You'll still have to swap out for a replacement if your watch has already fallen ill and won't recover, but the experience should be more reliable for already functional watches from here on out. Let fellow owners know how well the upgrade worked in the comments. [Thanks, Daniel]
Freescale fashions world's smallest ARM-powered microcontroller
If you're looking for an exceedingly tiny ARM-based microcontroller, Freescale says it's just cooked up the world's smallest. Dubbed the Kinetis KL02, the piece of kit is 25 precent smaller than the previous record-holder and measures up at a 1.9 x 2.00 x 0.56 millimeters. Having trouble visualizing exactly how small that is? Just take a gander at the photo above. A 48 MHz ARM Cortex-M0+ processor has made it onto the wafer-level chip-scale package and it's paired with 32KB of flash memory and 4KB of RAM. The outfit reckons it'll be a good match for 'internet of things' devices that are tight on space, and says it beats its older L Series kin in power efficiency. Manufacturer sampling for the KL02 is slated for March, while wide availability is penciled in for July, and it'll set buyers back 75 cents a piece when purchased in 100,000-unit loads. Hit the jump for more details in the press release.
Insert Coin: Arduino-compatible Pinoccio microcontroller sports battery, WiFi
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. It's been said that imitation is the sincerest form of flattery. Improving on a good idea, however, is truly the ultimate homage, according to the makers of the new Pinoccio microcontroller. Inspired by the Arduino, the brain trust behind the Pinoccio decided to take the stuff they liked about the popular platform -- ease of programming and low cost -- and add some features to make it even better. These include a rechargeable battery, a temperature sensor and a built-in radio that allows one Pinoccio with a WiFi shield to communicate wirelessly with other Pinoccios. The microcontroller also delivers performance that stacks up well with an Arduino Mega but at a smaller size -- the Pinoccio only measures a couple of inches long and an inch wide. The project is currently trying to raise $60,000 at Indiegogo, with supporters netting the standard Pinoccio by pledging $49 and a microcontroller with a WiFi shield for $99. For more details, feel free to check out the video after the break or peruse the project's Indiegogo page by clicking at the source link.
Arduino Esplora helps you learn microcontrollers without the pesky breadboard
Arduino is the go to board for most folks looking for an introduction to microcontrollers. That's largely thanks to its sizable community, ease of use and surprising versatility. But, there is one small stumbling block for those just looking to dip their toes in the ATmega-powered waters: you'll need to provide your own sensors, components and breadboard. (At least you will unless you're satisfied just making the built-in LED blink.) The Esplora bakes some of those essential bits and pieces right on to the board. It's crafted around the same core as the Leonardo, but adds an accelerometer, microphone, analog joystick, four buttons, a light sensor, temperature sensor, linear potentiometer and a buzzer to the mix. While the gamepad-like layout means you wont be able to connect to any of the dozens of Arduino shields out there, it does have a pair of TinkerKit inputs and outputs for expanding the Esplora's capabilities. There's also a place to connect an upcoming LCD module. The Esplora is available now direct from Arduino for €41.90.
Netduino Plus 2 offers four times the speed, full round of futureproofing (video)
The original Netduino Plus was a welcome alternative for Arduino developers that had its limits -- even networking was almost a step too far. Secret Labs doesn't want any of us to bump our heads on the ceiling with its just-launched Netduino Plus 2. The networkable, .NET-friendly developer board runs a four times faster 168MHz processor with double the RAM (over 100KB) and six times as much code space (384KB) as its two-year-old ancestor. Having so much headroom lets the team build common OneWire and Time Server code into the firmware; Secret Labs reckons that there's enough space that the Plus 2 can easily grow over time. The ports are just as ready for the future with four serial ports, software control of any add-on shields (including Rev C Arduino shields) and a new header that lets programmers debug both managed and truly native code at once. If the upgrade is sufficiently tempting, project builders just need to spend $60 today to enjoy some newfound freedom.
Arduino Micro shrinks your favorite DIY platform down to ridiculous proportions
With the Arduino Leonardo, everyone's favorite hackable microcontroller turned a new page. Now it's time to bring that simplified design and slightly expanded feature set to the rest of the family, including the itty-bitty Arduino Micro. The tiny, embed-friendly board was designed with help from Adafruit Industries, one of the biggest players in the DIY market. At the heart of the Micro is the same 16MHz ATmega32u4 chip that powers the Leonardo, which means all the necessary USB controls are baked into the processor. Obviously, the layout here is different, so you wont be mounting the Micro to any shields, but with 20 digital I/O pins, 12 analog input channels and seven PWM channels, there's plenty of room for wiring up your own expansions. Amazingly it crams all that capability in a package just 48mm long and 18mm wide. The Arduino Micro will be available exclusively through Radio Shack and Adafruit first before becoming more widely available next month. The board is available with headers for €21 (roughly $27) and without headers for €18 (about $23). For more, check out the PR after the break.
Butlers, lunar rovers, snakes and airboats: the best of Carnegie Mellon's Robotics Institute
How was your week? We got to spend a couple of days trekking around the Carnegie Mellon campus in Pittsburgh, PA to check out some of the latest projects from the school's world renowned Robotics Institute -- a trip that culminated with the bi-annual induction ceremony from the CMU-sponsored Robot Hall of Fame. Given all the craziness of the past seven days, you might have missed some of the awesomeness, but fear not, we've got it all for you here in one handy place -- plus a couple of videos from the trip that we haven't shown you yet. Join us after the break to catch up.
Hummingbird is a 'pre-Arduino' for kids (video)
It's an Arduino -- you know, for kids. Or, as BirdBrain Technologies' chief robot design Tom Lauwers put it, a "pre-Arduino." It's never too early to get kids into robot building -- or so goes the thought process behind this nectar-loving kit. At its center is a custom controller that can be used to manipulate a slew of different sensors, motors and lights, a number of which are included in the box. Getting started is extremely simple -- don't believe us? Check the video after the break, in which Lauwers connects two wires to get the whole process underway. The kit's also reasonably priced at $199 a piece. On top of the controller, you get a handful of LEDs, two vibration motors, four servos and light, temperature, distance and sound sensors. The kits are currently available through the company's site (click on that source link). Lauwers tells us that his company (which you may remember from last year's MakerFaire NYC) is working on a slightly more affordable option priced at around $130, which scales back a bit on the in-box components. Check out a conversation with Lauwers -- and a pretty awesome cardboard dragon -- below.
Ben Heck builds Arduino-based automatic sunglasses, beats David Caruso to the punch (video)
CSI: Miami might be out of production, but that doesn't mean we'll be deprived of casual eyewear flipping. Not if Ben Heck has a say in the matter, at least. His latest DIY project automatically swings a pair of clip-on sunglasses into view whenever it's too sunny outside: a photocell attached to an AT Tiny microcontroller checks the light levels and, through an Arduino-based AVR MKII language, tells a rotor to spin the glasses into place. No one will be labeled a fashionista with the requisite battery pack strapped to their heads, but the construction doesn't require CNC milling and won't destroy a favorite frame. We're only disappointed that the sunglasses won't play The Who on command... yet.
Researchers take full control of cockroach's movement, turn it into a wireless sensor
Built-in power supply? Check. Ability to survive anything? Check. Easy to control? Okay, anyone who's had a cockroach as an uninvited houseguest knows that's not the case. So, rather than re-inventing the biological wheel with a robotic version, North Carolina State university researchers have figured out a way to remotely control a real Madagascar hissing cockroach. They used an off-the-shelf microcontroller to tap in to the roach's antennae and abdomen, then sent commands that fooled the insect into thinking danger was near, or that an object was blocking it. That let the scientists wirelessly prod the insect into action, then guide it precisely along a curved path, as shown in the video below the break. The addition of a sensor could allow the insects to one day perform tasks, liking searching for trapped disaster victims -- something to think about the next time you put a shoe to one.
Back in the BBS days: how-to helps newbs navigate to a pre-internet playground
The web has an origin story, one that predates any cozy trip in the wayback machine. That's because where we're going, there is no internet -- at least, not as you now know it -- only Bulletin Board Systems. And to help guide curious digital natives on this journey back to the time tech forgot, a programmer by the handle of Proppelerpowered has whipped up a how-to that leverages nothing more than a microcontroller-based microcomputer and BASIC knowledge. The brief step-by-step, listed over on Instructables, requires intrepid geeks to build a Pocket Mini computer, which purportedly takes only "an evening," after which they'll have to tinker with some low-level coding to complete the connection setup, hitch a ride online via PC and then link up with any number of active BBSs around the world. For the purposes of this beginner guide, you'll have instructions for access to a Canada-based Commodore 64 clearly laid out. But the more adept are encouraged to swap out the standard setup for an ANSI terminal and wade into serious retro-gaming waters (Trade Wars, anyone?). Hit up the source below to peek the blow-by-blow and see if this hack's made for you.
Cornell students build spider-like robotic chalkboard eraser out of Lego, magnets, fun (video)
While you were trying to pass Poetry 101, Cornell seniors Le Zhang and Michael Lathrop were creating an apple-polishing Lego robot that automatically erases your prof's chalkboard. A final class project, the toady mech uses an Atmel brain, accelerometers for direction control, microswitches to sense the edge of the board, magnets to stay attached and hot glue to keep the Lego from flying apart. As the video below the break shows, it first aligns itself vertically, then moves to the top of the board, commencing the chalk sweeping and turning 180 degrees each time its bumpers sense the edge. The duo are thinking of getting a patent, and a commercialized version would allow your teacher to drone on without the normal slate-clearing pause. So, if designing a clever bot and saving their prof from manual labor doesn't get the students an 'A', we don't know what will.
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?
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.
Kinetis L Series MCUs use ARM Cortex-MO+ to sip least power, cost 49 cents each per 10K order
Freescale aims to drag 8- and 16-bit manufacturing into the modern era with a 32-bit MCU that's cheaper than a cup o' Joe. The ARM Cortex-MO+ based Kinesis L series MCU is now available in alpha to interested parties, it's capable of sipping a scant 50 µA/MHz of power and will cost just $0.49 when you buy 'em in lots of 10,000. While the cheap chips will no doubt go on to help power the internet of things, the associated debut of a $12.95 development board coming in August will also be a boon to developers and hobbyists. The platform will allow "quick application prototyping and demonstration" according to the company, and provide a GUI tool for generating start-up code and device drivers. So, if you've gotta have that new beer dispenser mock-up running at a full 32-bits, check the PR after the break.
