Adafruit's Circuit Playground show to teach kids about electronics with cute components
Adafruit already welcomes newcomers to do-it-yourself device culture, but it still assumes a certain amount of comfort with coding and soldering. The shop now wants to accommodate the most basic of beginners by starting a children's web series that teaches electronics. Circuit Playground will provide activities, songs and stories that put a friendly face on engineering, in some ways very directly: many of the shows will involve big-eyed characters (and, naturally, corresponding toys) like Cappy the Capacitor. Although the series doesn't start until March, it could be vital to a generation of kids growing up immersed in technology -- and ultimately create a larger customer base for Adafruit in the process.
Cambridge researchers translate graphene into printable circuitry material, bring basic 'Skynet' factory to you
Yes, graphene is amazing and possesses many useful / otherworldly properties. The ability to use graphene itself to print flexible, transparent thin-film transistors via an inkjet printer is just another one of them. Over at the University of Cambridge, researchers have discovered that it's possible to print standard CMOS transistors using a graphene component. Provided the graphene is chipped off a block of graphite using a chemical solvent and the larger (potentially print-head blocking) chips are removed, it can be turned into a polymer ink which can then run through a conventional inkjet printer. The potential result of this is flexible, transparent and wearable computer circuitry coming from ordinary printers as opposed to several multi-million-dollar machines in a factory, which has long been the historical standard. Besides, who wouldn't want to print their own circuitry on a PhotoSmart MFP rather than whatever report might be due the next day?
How Arduino got its start: a behind the scenes revelation
Plenty of tales have cropped up through the years focusing on the roots of Arduino -- a tiny circuit board that holds a special place in the heart of every modern-day DIYer -- but a recent expose from the folks at Ieee Spectrum has a behind-the-scenes look that'll impress even historians. Massimo Banzi is the name, and Bar di Re Arduino is the place. The former is hailed as an Italian cofounder of the project he dubbed Arduino in honor of the latter, and in time, four more folks would join him to create what would become a complete gamechanger in the universe of homegrown electronics. We've covered initiatives built on Arduino for years here at Engadget. Everything from sigh collectors to early warning systems for pastry chefs has been built around the platform, and the story of how we got to the place we are now is a fascinating one. We won't introduce any spoilers here -- tap that source link below to enjoy at your own pace.
Researchers wed quantum processor with quantum memory, quaziness ensues
Quantum computing has a long way to go before becoming truly mainstream, but that certainly hasn't stopped us from indulging in dreams of a qubit-based existence. The latest bit of fantasy fodder comes from the University of California, Santa Barbara, where researchers have become the first to combine a quantum processor with memory mechanisms on a single chip. To do this, Matteo Mariantoni and his team of scientists connected two qubits with a quantum bus and linked each of them to a memory element, capable of storing their current values in the same way that RAM stores data on conventional computers. These qubit-memory links also contained arrays of resonators -- jagged, yet easily controlled circuits that can store values for shorter periods of time. The qubits, meanwhile, were constructed using superconducting circuits, allowing the UCSB team to nestle their qubits even closer together, in accordance with the von Neumann architecture that governs most commercial computers. Once everything was in place, the researchers used their system to run complex algorithms and operations that could be eventually used to decode data encryption. The next step, of course, is to scale up the design, though Mariantoni says that shouldn't be too much of a problem, thanks to his system's resonators -- which, according to him, "represent the future of quantum computing with integrated circuits."
SparkFun intros IOIO for Android, a hack-free breakout box to get your mind spinning
Meet any seasoned techie, and they'll likely spin whimsical tales of computing's early days, and the challenge of finding a practical use for a device with seemingly limitless potential (you know, like feeding your cat while you sleep). A new product from SparkFun promises to bring this old-school awesomeness into the smartphone age: introducing IOIO (pronounced yo-yo), a breakout box that enables any Android 1.5+ device to control electronic circuits from within Android's applications. Designed in collaboration with Google, Spark's PCB connects to your phone over USB, working its magic through a Java library that hooks into your apps. This DIY paradise will begin shipping in a few weeks, and can be yours for $49.95 on pre-order. We've already witnessed some clever mods with IOIO, and when it sent a real alarm clock ringing, we couldn't help but smile. Crack one yourself after the break.
Toshiba outsourcing semiconductor production to rival Samsung
'Tis the season for manufacturing deals? Sure seems it. Merely hours after Sony announced its intentions to buy back Cell chip fabrication facilities from Toshiba, it looks as if Tosh is about to enter into yet another agreement. In this case, it'll be outsourcing the unprofitable production of semiconductors to rival Samsung, which will be responsible for churning out the brains behind a number of smartphones, televisions and digital home appliances. Numerous sources have explained that Toshiba is interested in realigning its focus onto the blossoming memory chip business, and moreover, its hoping to evade costly facility upgrades that would be necessary to remain competitive in the system LSI business. In other words, the company is dodging investment costs and placing a greater emphasis on a sector that's already profitable (NAND flash production, for those curious), and after the Oita plant is handed off, it'll be used to make image sensors in digital cameras. The Nagasaki plant, as we heard earlier, will be handed over to Sony. Toshiba's stocks were sent northward after investors welcomed the news, but of course it remains to be seen what kind of consumer impact this will have. Whatever the case, we certainly hope Toshiba never runs into any trouble with Sammy -- it's not like its top brass can be touched, regardless of infraction.
Researchers develop programmable molecular circuitry for living cells
Researchers at the UCSF School of Pharmacy's Department of Pharmaceutical Chemistry, led by Christopher A. Voigt have just published a paper which promises to get your circuits moving. The team has been working with E. coli bacteria to build logic gates like the ones found in computers directly into cells, making it possible to rewire and program them. The simple logic gates used in the experiment were built into genes then inserted into E. coli cells. The logic gates then acted as the communicator between the separate strains, allowing them to be connected together.The use of logic gates in cells could make it possible to tackle more complicated processes, so that science can begin to use cells at the molecular level for biomedical advances.
Squirt water gun robot pesters raccoons, takes orders from Android (video)
It's not uncommon to see Mr. Android and Sir Arduino team up in the world of homegrown robotics, but Squirt has managed to hop out of the me-too crowd with a downright charming control scheme (and even more charming looks). Put simply, this water gun robot was designed to "water plants and chase away raccoons," but from a broader perspective, the creator was looking to demonstrate how robotics could be used in small irrigation and well systems. Better still, this is far more than just a robot that's controlled remotely via smartphone; if you switch it into 'guard mode,' it'll search and destroy -- pelting anything "that moves" with a blast of water. And yeah, it can also be controlled via SMS, so even the cats can't celebrate too quickly once the owner heads out for work. Hit the source link to find out more on how this masterpiece was constructed, or head beyond the break for a quick demo vid.
SuONOIO synth takes soundgeeks from zero to tweaking in fewer than 60 cycles (video)
We'll admit that sometimes it doesn't take much to get our engines running here at Engadget HQ. If you can throw a couple of knobs, exposed circuitry, a 9v battery, and a sense of adventure into a semi-coherent package, we'll be pleased as punch. The SuONIO synthesizer, therefore, makes us very happy indeed. SuONOIO is the band of former Nine Inch Nails keyboardist Alessandro Cortini, and SuONOIO is a pint-sized slab of silicon that comes bundled with a digital copy of the band's latest album. Delivered bubble-wrapped in a hand-stamped cardboard box -- if you've ever had the pleasure of unboxing an Arduino kit, you'll know the feeling -- it's pre-loaded with two banks of samples that were used to create the album. Although it's a sample-based instrument, it's the user's job to create new noise using an array of jumper-activated effects and mixing techniques. It's not quite as expansive as an MPC, but as any good experimentalist knows, there's a lot to be gleaned from limitations and new interface paradigms. Read on for our impressions of the noisebox and a tour of its inner workings! %Gallery-107941%
High tech smoke signals: a luddite's dream (or nightmare?)
"For Those Who Can See" is an art project by Daniel Schulze. Using smoke machines, speakers, and a 7 by 7 grid of concrete slabs, the speakers are programmed to pulse at specific intervals, triggering the smoke when they do. The slabs of concrete have been drilled with holes, resulting in 'modern smoke signals.' Schulze's project is not yet fully realized, and a complete installation is set to debut at DMY Berlin. Below is a video mockup of the project.
Bleep Labs builds Arduino-based Nebulophone, wants to sell you one
What do you get when you mash together an Arduino-based synth with a Stylophone-like keyboard? A month ago, even we wouldn't have known, but now that Handmade Music Austin has come and gone, we're happy to say that this beautiful concoction leads to the creation of a Nebulophone. Unfortunately, there's no video (yet) to showcase what this musical wonder can do, but we're told that it has "adjustable waveforms, a light controlled analog filter, LFO and an arpeggiator that can be clocked over IR." Hit the source link if you're looking for all the code, schematics, and instructions necessary to give yourself a weekend project, and feel free to drop the guys / gals there a line if you're interested in just buying one.
NEC's fancy new wiring technology could lead to slimmer LCD HDTVs
While it's pretty much a given that HDTVs are going to slim down from one CES / CEDIA to another, you probably wouldn't think that wiring schemes would be the catalyst for making it happen. NEC Electronics has just revealed a "next-generation connection technology for the circuitry in large LCDs" that will enable big screens to get all the more thinner. Essentially, the tech is "specific to the wiring used to transfer signals from the image processing board to the driver chips that are fitted to the periphery of the LCD panel and control the pixels." Currently, a Full HD 37-inch LCD TV requires right around 21 wires to make the magic happen; with NEC's approach, just 8 would be needed. The company expects to have a "practical version" ready to roll sometime in 2009, so we're totally expecting credit card-thin LCDs in January 2010.
DeepNote Guitar Hero bot reveals its secrets on video
Don't even try to deny it -- you've been holding one mean grudge against that ridiculously accurate DeepNote bot ever since you saw it dominate Guitar Hero in mid-July. Really though, all that pent up aggression is completely unnecessary, and if you've been fruitlessly aiming to concoct one of your own, we've found the perfect place to start. The video posted up after the jump gives a fantastic overview of how the device actually works, and while it's far (very far) from simple, it's nothing the seasoned DIYer couldn't handle on an extended weekend. Give it a look if you're head over heels for PCBs and flashing LEDs (oh, and shameless rock 'n roll).[Thanks, Jeremy]
Another breakthrough purportedly brings us closer to quantum computing
In reality, quite a bit of time has passed since we've heard of the next great leap in the (seemingly) never-ending journey towards quantum computing, but we're incredibly relieved to learn that at least someone is still out there, somewhere, pressing on. An international team of researchers have reportedly shown that they can "control the quantum state of a single electron in a silicon transistor, even putting the electron in two places at once." Essentially, the team is using tiny semiconductor transistors to "control the state of a quantum system," but there is still a long ways to go before any of this is meaningful. The crew managed to discover a few things by chance, yet to create a quantum computer, they would need to "position atoms of arsenic (or some other material) in the transistors more reliably." For those of you way too geeked out, fret not -- we'll let you know when all of this technobabble finally amounts to something.[Thanks, Chris]
Machine Collective reveals modular prototyping platform
While Bug Labs may have brought modular gadget kits to the forefront, you won't find us kvetching about yet another formidable opponent. Machine Collective has just launched a website to showcase its modular prototyping platform, which essentially consists of a number of interchangeable I/O modules "designed to work with development platforms such as Arduino and Wiring." Needless to say, the possibilities for DIYers and electrical engineers are pretty much endless here, though you'll have to "wait a few weeks" before excitedly beaming in your order and credit card information.[Via MAKE]
An effortful DIY alternative to a rumbling DS Lite
Those with loads of disposable income probably wouldn't mind ponying up for the relatively inexpensive rumble cartridge made specifically for Nintendo's DS Lite, but the frugal (and engineering) sets will certainly appreciate Xyzzy's efforts. After dissecting a Pokemon Pinball GBA game and ripping the rumble motor from a salvaged Nokia 5100, he put his circuitry knowledge to work and conjured up a rumble device that fit flush in the DS Lite and cost him nothing more than a little blood, sweat, and tears. Be warned, however, that this guide isn't for the faint of heart (or those who don't natively speak in 1s and 0s), but feel free to tag the read link and get busy if you dare.[Via Joystiq]
Printed organic RFID circuits set to collect statistical data
In order to truly judge the effectiveness (or lack thereof) of a newfangled technology, we all know trial by fire is the only way to go. Hence, it follows logic that about 1,000 printed organic RFID tickets will be tested at the Organic Electronics Conference this September in Frankfurt, Germany. The badges will be converted by Bartsch and are "set to be used to monitor the flow of attendees during the two-day conference and exhibition." Deemed the "first ever printed, low-cost organic tickets," these devices will be trialed in order to judge their data collecting abilities and to show whether or not these would be good candidates for use in "public transportation and logistics" applications. So, for those of you heading over to this here event, make sure you're packin' some sort of RFID jammer when waltzing through the door -- you know, just to give these newb tags an unexpected challenge on their first day at work.
DIYer concocts homegrown GSM-GPS tracking device
As we've seen time and time again, the desire to really know what's going on behind the scenes seems to be a growing trend, and while there's a number of pre-fabricated methods to keep track of your vehicle, mischievous offspring, or straying SO, why not take a little initiative and build an alternative yourself? Thankfully, a crafty DIYer has done just that, and has spelled out the details in order for you to replicate his work. The homegrown device is built around the Telit GM862 GSM-GPS module, and all told, he spent around $286 to scratch the mobile GPS itch. The device is small enough to be crammed into nearly any nook or cranny, and can transmit its position via text message to the owner. So go on, give the read link a visit and bust out your credit card -- just be sure to not let the soon-to-be-tracked individual know what you're up to, capiche?[Via NaviGadget]
Researchers develop scalable circuit printing technique
As if there weren't enough "almost theres" in the world of printable circuits, now we've got yet another team developing their own iteration of a printing press for electronics. The group, which includes scientists from DuPont and Organic ID, has reportedly "fabricated a printing plate used to print the source-drain level of an array of thin-film transistors," essentially solving some of the low-resolution constraints seen on prior competition. The goal is to eventually posses the ability to "print large, flexible circuits using machines similar to printing presses," and while it seems to be a ways from commercialization, initial testing and comparisons to more traditionally-created transistors have produced glowing results.[Image courtesy of HowStuffWorks]
Wii circuitry changed to thwart modchips?
Reports are coming in from Taiwan and Germany that Nintendo has updated the Wii's motherboard with its latest shipments of the console. According to MaxConsole, one of the solder points has been removed from the altered board, shutting out quicksolder modification chips like WiiKey. Other similar tools that don't use the missing solder point should not be affected. DigiTimes suggests that these changes to the circuit layout were made with the sole intent of preventing piracy by blocking these warranty-voiding installations. If that's the case however, why did Nintendo only take steps to block just the WiiKey, a modchip that was released only several weeks ago?There were similar concerns in the past about Mario Kart DS updating the Nintendo DS' firmware as an anti-piracy measure, but it was quickly discovered that the handheld was only saving its WiFi settings. It seems far more likely that Nintendo has had the Wii's revised motherboard planned for months, and that locking out any modification methods was an unintended result.
