DIY'er makes his own conductive ink, teaches you how to do the same
There are DIY projects that you should do at your own risk, and then there are DIY projects that you should do at your own risk. This conductive ink concocted by Jordan Bunker falls into the latter category, but it should be relatively straightforward for those who know what they're doing (or those with proper supervision), and it results in a product that's markedly cheaper than existing off-the-shelf alternatives (Jordan spent around $150 for a decent-sized batch). That can then be used for any number of electronics projects, of which you'll have to discern your own degree of danger. Jordan's promising a video soon, but you can find the complete instructions for making your own at the source link below in the meantime.
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?
Scientists make magic auto-origami using ink and light (video)
We've seen nano-origami and robo-origami, but nothing quite as rapid and simple as this. Researchers at North Carolina State University have figured out how to neatly fold plastic using infrared light and an inkjet printer. Deep black lines are printed onto the plastic sheets, which then absorb the light and cause the material to fold without anyone having to touch it. The wider the line, the greater the angle of each fold, so it's possible to set, say, a 90-degree bend for a cube or 120 degrees for a pyramid. What's more, by giving the lines different patterns, folds can be made to work in specific directions, potentially producing the most perfect, most hygienic bento box that's ever contained your lunch.

Gold Capped: Cataclysm glyph addons
Every week, WoW Insider brings you Gold Capped, in which Basil "Euripides" Berntsen aims to show you how to make money on the auction house. Email Basil with your questions, comments, or hate mail! The glyph market has spawned quite a few of the important modern auction house addons. It's a uniquely challenging market, as there are hundreds of different products, each with their own balance of suppliers, buyers, and materials. The challenges faced by early glyph producers were met by a hodgepodge of fairly complex addons and macros, and only recently have unified solutions began to appear. I remember that at one point, I had addons to: Keep track of how many glyphs I had on the AH, in various characters' banks and in their inventories. Allow me to queue a list of glyphs and build a materials list (that allowed me to buy the vendor mats with one click). Automatically queue enough glyphs in the second addon to assure that I kept stock levels at my desired level. Automatically post every glyph I made onto the AH. The tasks needed for this market are not unique, and so the most important tool that can trace its origin to the glyph market is certainly TradeSkillMaster. TSM is an addon that I've covered before, and it's built from the ground up to be perfect for glyphs. It's also perfect for a lot of other markets, but mostly those you can treat like glyphs.
Gold Capped: Selling glyphs in Cataclysm, part 1
Every week, WoW Insider brings you Gold Capped, in which Basil "Euripides" Berntsen aims to show you how to make money on the auction house. Email Basil with your questions, comments, or hate mail! When Cataclysm launched, it came with a design change for the glyph system. Whereas players who wanted to change glyphs previously had to buy a new one to overwrite an existing one, they could now use Dust of Disappearance to overwrite their glyphs with any of their learned glyphs. I split markets in WoW into two segments: Items that players will only buy once per character Items that are bought multiple times per character While glyphs are now firmly in the first category, honestly, they seemed as if they were there anyway. The vast majority of glyph demand, throughout Wrath of the Lich King, was not generated by elite raiders or PvPers keeping stacks of commonly used glyphs in their bags so they could micro-optimize, but rather from people leveling new characters. The demand for glyphs remains strong, and that means someone is making money.
E Ink develops flashing displays for cloth and Tyvek, experiments with color FMV (video)
Yesterday, we found out that E Ink Holdings won't be releasing a new electronic paper display until 2012 and now, we know why. Turns out, the Pearl manufacturer has been busy refining its screen tech acumen, and extending it to a variety of different surfaces. The Digital Reader recently caught up with Sriram Peruvemba, E Ink's VP of global sales and marketing, who confirmed that his company has developed a SIRF display that can be printed on cloth, effectively turning any t-shirt into a flashing, black-and-white billboard. E Ink's engineers have taken a similar approach to Tyvek cloth, creating a display that could make your vanilla postal envelopes a little more dynamic. And, as you might expect, the company has been experimenting with an e-ink screen capable of supporting colorful, full-motion video -- though it looks like E Ink still needs to smooth out some of the grainy kinks in that one. All three demo videos are available for your viewing pleasure, after the break. [Thanks, Nate]
New silver-packing transparent conductive film could mean more durable touchscreens
We first heard of the wonders of silver ink back in 2009, but it wasn't until earlier this year, with talk of 3M's new capacitive touchscreens, that we experienced its real-world potential for display technology. Well, it looks like 3M's not the only name in the Ag game, in fact Tokyo-based Toray Industries recently announced the development of a transparent conductive film that ditches the traditional ITO (indium tin oxide) for silver wire. In order to produce this new material, a layer of Ag wires, measuring several hundred nanometers, is applied to a polyester (PET) film by way of a wet method. The result, the company said, is a more flexible, durable, and transparent film that is well suited to touchscreens of just about any size. There's no word yet on when the film will appear on real-deal devices, but we'll definitely keep an eye out for the silver screens. Full PR after the break.
Visualized: Overturned ink-carrying tractor-trailer paints the town red... literally
What you're looking at in the psychedelic photograph above is the result of an overturned tractor-trailer in Peabody, Massachusetts that was carrying a load of -- you guessed it -- printer ink. Fortunately the spillage isn't believed to cause any environmental damage, but unfortunately you can't just take your empty cartridges down to Peabody for a quick fill-up. No word on how this may affect HP's bottom line, but since the markup on ink is absurd, we're sure they'll have enough dough to cover the loss. Bonus shot after the break. [Image: Boston.com]
HTC launches 1.5GHz, 7-inch Flyer into the tablet wars (update: hands-on video!)
Boy oh boy, HTC is entering the tablet arena with quite a bang. The company has just taken the wraps off its brand new 7-inch Flyer Android tablet, which touts a 1.5GHz single-core CPU, 1GB of RAM plus 32GB of flash storage, an aluminum unibody construction, 1024 x 600 resolution, a tablet-optimized version of Sense, and... what's this, a pressure-sensitive stylus! The HTC Scribe trademark we saw floating around in legal waters turned out not to be the branding for a tablet, it's actually the name HTC gives to the technology enabling what it calls a "groundbreaking pen experience." Other details include a 5 megapixel camera on the back paired with a 1.3 megapixel imager up front, a 4000mAh battery rated to last for four hours of continuous video playback, and memory expandability via a microSD card. The Flyer will ship in Q2 2011 with Android Gingerbread 2.4 on board. HTC says it'll be indistinguishable from 2.3 as far as the end user is concerned, though we all know it won't be quite as good as the 3.0 stuff. We're told not to worry, however, since the new version of Sense being introduced with the Flyer will be the focal point of the company's software offering. As far as HTC is concerned, Sense matters more than the underlying platform, and the reason Honeycomb isn't the shipping OS here was explicitly stated as HTC not having enough time with the latest Google code to customize it to the full requirements of Sense. Guess that settles that. There are a couple more software enhancements, both marking the introduction of the fruits of HTC's recent deals: OnLive cloud gaming will be coming with the Flyer in the form of an app you open up to access the web-connected bored-relieving service, while that Saffron Digital acquisition has turned into an HTC Watch app for movie streaming and downloading. We spent a bit of quality time with a Flyer unit recently, although we weren't allowed to turn it on, and our early impressions are rather mixed. On the one hand, we do appreciate the ruggedness and durability that's afforded by the one-piece aluminum shell, but on the other, the Flyer is quite the chunky beast in your hands. We'd imagine strapping in such an extra-speedy processor is the main culprit for its extra girth, though the Flyer is, ironically enough, not terribly light either. We found it heavier and generally a lot less polished from a design perspective than Samsung's Galaxy Tab. Anyhow, HTC should have functional units for us immediately following its MWC presser this morning, and we'll be delving in deeper with this super-specced device. Hang tight! Update: Pictures of the Flyer can now be explored below and we have video awaiting your audience just past the break. Update 2: HTC has tweeted that the Flyer will be updated to Honeycomb in Q2. %Gallery-116694%
Plextronics rolls out next-gen OLED ink, promises bigger, better OLED displays
A bottle of ink may not exactly seem like the key to bigger, better, and cheaper OLED displays, but that's just what Plextronics is promising will result from its new "next generation" Plexcore OC NQ ink. That's particularly notable because it's a non-aqueous, inkjet-printable ink, and is intended specifically for use with so-called solution-processed, phosphorescent OLED technology (as opposed to the vapor processing now commonly used), which at least some folks are betting on as the next big thing for OLED manufacturing -- recent tests have also shown significant advances for the technology, including a lower operating voltage and boost in lifetime over previously tested systems. What's more, while it's still in the testing phase now, Plextronics says it expects the ink to be broadly available to manufacturers sometime next year, which should mean that actual OLED displays using it will follow sometime thereafter.
Pseudomorph dress is just begging for your pocket protector (video)
We're not going to pretend to understand haute couture. But when Anouk Wipprecht hooks up a nine-volt battery to a dress for the purpose of dribbling ink down the front from a pneumatic udder octet, well, you've just caught the attention of card-carrying nerds everywhere.
Used ink cartridges repurposed as sci-fi movie mementos
We've seen ink cartridges enlisted to provide light and as the basis for a bike path, and so many other things that it makes us wonder if we missed the boat by using them to, you know, print stuff. Apparently the kids at the Ink and Media Blog feel the same way, so rather than throw out the used cartridges, they handed 'em off to an artist named Faith Pearson, who used 'em to recreate scenes from her favorite sci-fi movies. They look great and sure as hell beat the C-SPAN re-enactments that we did last summer using Popsicle sticks and a broken Lego Mindstorms kit. Hit the source link to see for yourself.
The HP eStation Zeen, the Zeus printer, and everything we know about them
We've been flooded with a deluge of tips about the HP Zeen ever since we posted those first FCC images of the tablet device this morning, and it's actually a little surprising at how perfectly everything aligns. We've now had multiple tipsters confirm that the Zeen is an e-reading-focused Android tablet with the unique ability to connect directly to an HP printer and function as its interface without the need for a computer. But that's not all -- here's everything else we know: The Zeen is a capacitive tablet running a HP skin on top of Android 2.1 -- it won't get shifted to webOS, and it's not clear if it'll get upped to Froyo before launch given the development time required. It has capacitive touch buttons, a SD card slot, video support, and at least some prototypes have cameras with a special webcam app installed. The goal is for the HP home screen and skin to be the only home screen available, but that hasn't been fully implemented yet. E-reading is a major focus, and the Zeen has "significant" integration with the Barnes & Noble Nook bookstore and ecosystem. Makes sense, as the Nook itself is based on Android, and being able to print e-books from the Zeen would be a huge differentiator -- and a great way for HP to sell more ink. The Zeen will come in two configurations: a $399 bundle with a new printer called Zeus and as a standalone unit for an unknown price. The Zeus has its own "basic" control setup, but when the Zeen is docked it provides a rich interface to the printing functions -- presumably a web-connected interface like the one HP's been moving towards with other printers. Despite the CQ model number, the Zeen is a straight HP product, with a laser-etched logo on the back. So that's what we know about this enigmatic product. It certainly adds up -- HP has long said one of the reasons it bought Palm was to use webOS as a consistent interface to other connected devices like printers, and it only makes sense that the company was working on executing that strategy with an OS like Android long before Jon Rubinstein and company joined the team. Besides, how better to sell more ink than by making it easy for consumers to hit Facebook and print pictures without having to use a computer at all? It's certainly interesting -- we're waiting patiently to see when and where the Zeen next appears.
Recycled ink cartridges used to build bike path in Australian National Park
We've certainly witnessed one too many ink cartridges perish at the hands of a crushing radial, but those instances all stemmed from fighting the good fight with frustration. Australia's National Park Service is giving those fed up with paying far too much for far too little ink another, more reasonable method of extinguishing their anger with the creation of a 17 kilometer long bike path connecting Alice Springs to Simpsons Gap in West MacDonnell National Park. 'Course, recycled ink cartridges are just part of the eco-friendly solution, but it's not too far-fetched to think that another couldn't be built entirely from what your own corporation trashes in a single month, right? On a related note, that guy looks like he's having an insane amount of fun. Jealous. [Image courtesy of Centralian Advocate]
Will we pay more for magazines on the iPad?
Business Insider has a post up from AdAge about magazine pricing on the iPad, and they've got bad news for anyone planning to transfer all of their magazine subscriptions to Apple's magical device: It'll cost ya. While a year's worth of Popular Mechanics goes for $12 from the publication's website (or even cheaper if you can pick it up from Amazon or that random kid wandering your subdivision selling subscriptions), the iPad subscription will cost $29.95; that's over twice as much. You can buy a year's worth of Wired on Amazon for just $10, but one issue on the iPad costs you half of that. Why? At first, the cost seems like a ripoff; publishers don't have to pay for paper, ink, or postage, so you'd think the content should actually be cheaper. Then you calculate in the cost of interactive designs and features, researching new technologies, and creating new workflows, and creating an iPad version of the magazine starts to get more expensive. Throw in that publishers are wary of pricing their content too low, and you get a higher price than a print subscription -- which plenty of readers will probably pay anyway. That's a pretty fragile pricing state, though; e-books are already cheaper than their print versions, and while comic books are the same price in the store as they are on something like the Marvel application, you have to think that those prices will drop too. As usual, early adopters will pay the most, but I wouldn't be surprised to see the price of "e-magazines" drop as publishers and consumers alike even out the rough edges of the transaction.
Stanford wants to roll its own paper batteries
It was only a couple of months ago that MIT was wooing us with the energy-preserving properties of carbon nanotubes, and in a classic act of oneupmanship Stanford has now come out and demonstrated paper batteries, which work thanks to a carbon nanotube and silver nanowire "ink." We've seen this idea before, but the ability to just douse a sheet of paper in the proper magical goo and make a battery out of it is as new as it is mindblowing. Battery weight can, as a result, be reduced by 20 percent, and the fast energy discharge of this technology lends itself to utilization in electric vehicles. The video after the break should enlighten and thrill you in equal measures.
Some new WoW-related tattoos in our gallery
Time once again for us to update our WoW tattoo and license plate galleries with submissions from you readers. This time around, we've got a few new updates to the tattoo gallery, including Raevyndra of Rexxar's new arm ink above, these two pieces sent in by Tonya, and Sean J.'s pretty elaborate Horde crest. If tattoos are your thing, there's definitely some cool WoW-related ink to check out in there. This is the only new license plate addition at the moment, but if you happen to have a WoW-related plate on your car that we haven't seen just yet (or can grab a picture of someone else's -- just stay safe if you happen to be driving at the time), be sure to send us a note on the tipline. Stay tuned for more tats and plates when we see them. %Gallery-40471%
Apple's patent application for pen-based computer remembers fingers can't write
Uh, um, ok... remember how Steve Jobs called the finger, the "best pointing device in the world" while chiding the stylus? Well, guess he wasn't lumping handwriting capabilities in with his lambasting if there's anything to this patent application for recognizing and processing "ink information" from a pen-based computer system that went public today (filed in July 2009). Naturally, the patent app makes liberal mention of tablets as the most recognizable pen-based computing systems; something that will certainly fuel speculation about the much rumored (it is still a rumor right?) Apple tablet possibly sporting a, gulp, stylus. Now go ahead and check the video after the break and listen to Steve Jobs describe the insanely great "pointing device we're all born with" (1:54) in addition to how Apple "invented a new technology called multi-touch" (2:03) with the patents to prove it (2:27 and 6:19). Oh MacWorld 2007, isn't there anything you can't do?
Xerox announces silver ink, keeps printable electronics dream alive
Here comes Xerox, huffing and puffing its way back from obscurity with what it believes is a revolutionary new advancement. Its brand new silver ink and related printing technologies promise to make it possible for the lazy or breadboard handicapped among us to print their own circuit boards atop plastics, film, and even textiles. The wizardry of it lies in the company's development of a metallic ink with a melting point lower than that of plastics, which allows the former to be laid (in liquid form) atop the latter. It's all very neat, and the potential for flexible, lightweight, disposable electronics is well and good, but haven't we heard this all before?
Empty ink cartridges repurposed as glorious lamps
We all know that those ink cartridge refills never really function perfectly as advertised, so rather than paying too much to have a lackluster printing experience, boxlightbox has decided to repurpose his empty Epson boxes into prepossessing lighting instruments. The simple (albeit masterly) lamps maintain the iconic presence of an ink cartridge while still fitting into the overall feel of an art deco home. At $350, the sensational Ink-Cartridge Chandelier shown above certainly isn't the cheapest of fixtures, but for those who spend entirely too much time at Kinko's, it's totally worth the investment. Hit the read link for more ways to spend money that you don't have -- or, you know, to just get a few ideas for scratching that DIY itch. [Thanks, David]
