Sharp to Introduce 4K Professional Display with IGZO Panel

Sharp to Introduce 4K Professional Display with IGZO Panel: Sharp Set to Release 4K IGZO Display for Japanese Market

Sharp Corp. this week announced a new professional display for CAD works that not only features 4K-class resolution (3840*2160), but will also be based on a panel based on Sharp’s promising IGZO technology. The new professional display has large 32” diagonal and is currently among the largest PC displays on the market.
The PN-K321 is Sharp's latest 32” ultra-high-definition (3840*2160) display and features smaller transistors (TFTs) in the LCD panel compared to conventional displays, thereby increasing the amount of transmitted light per pixel. Because 4K displays enable clear, crisp display of large amounts of information ranging from small text to detailed images on one screen, they boost operational efficiency by sparing users the need to scroll frequently.

Burglar suspected of using Arduino-Onity hack to rob hotel rooms

Burglar suspected of using Arduino-Onity hack to rob hotel rooms:

Can anyone argue against this being the least-secure hotel room lock on the market? Regular readers will recognize it as an Onity key card lock. A few months back a glaring flaw in the security was exposed that allows these locks to be opened electronically in less than a second. So we are not surprised to hear that a series of hotel room robberies in Houston are suspected to have been performed using this technique.
The image above is from a demonstration video we saw back in October. That hack used an Arduino-compatible chip inside of a dry erase marker as an end-run around the lock’s electronics. It reinforced the warning sound by [Cody Brocious] when he presented the exploit at this year’s Blackhat conference. The barrel jack on the outsideof the door lock doubles as a 1-wire communications port and that is how an attacker can gain access. Investigators can find no other means of entry for these thefts.


We applaud one…

Staples to get in-store 3D printers

Staples to get in-store 3D printers:
Some Staples stores in Belgium and the Netherlands will have MCOR color 3D printers that will print out model-files uploaded to a store website for in-person pickup. MCOR printers use plain pulp paper as build material, so the resulting models will be essentially cellulose, dye and glue, and should be easy to recycle.


Staples’ Easy 3D will offer consumers, product designers, architects, healthcare professionals, educators, students and others low-cost, brilliantly coloured, photo-realistic 3D printed products from Staples stores. Customers will simply upload electronic files to the Staples Office Centre and pick up the models in their nearby Staples stores, or have them shipped to their address. Staples will produce the models with the Mcor IRIS, a 3D printer with the highest colour capability in the industry and lowest operating cost of any commercial-class 3D printer.The press release promises that this technology will be made available in other S…

Android VOIP phone and Raspberry Pi mate for an intriguing PBX setup

Image
[Ward Mundy] has found something great by combining a GXP-2200 phone with Raspberry Pi to create a private branch exchange. So the idea behind a PBX setup is kind of like a company intranet. All of the phones in the system are assigned an extension number and have access to the internal system functions like voice mail, and sharing phone lines to the outside world. We’ve talked about using an RPi as a PBX before, but the high-tech phone he’s using this time around pulls everything together remarkably well.
The GXP-2200 is available for under $200. It runs Android and has a full color touch screen pictured above. It is marketed as a multimedia phone and indeed it brings Skype and Google Voice to the party. But it also offers six SIP lines. The hardware even seems to be planned for this type of use as the phone offers a second Ethernet port to which the RPi board can be connected. In this example [Ward] simply screws the RPi to the phone’s plastic stand and connects the two using a six-i…

Google Books team open sources their book scanner

Google Books team open sources their book scanner:

It’s no secret that Google has been scanning hundreds of thousands of books in the hope of recreating the Library of Alexandria. Publishers and authors really didn’t like that idea, so the Google books team is doing the next best thing: they’re releasing the plans for a very clever book scanner in the hope others will pick up the torch of creating a digital library of every book ever written.
Unlike some other book scanners we’ve seen that rely on an operator manually flipping pages, this linear book scanner turns the pages automatically with the help of a vacuum cleaner and a cleverly designed sheet metal structure after passing them over two image sensors taken from a desktop scanner.
The bill of materials comes in at around $1500, but according to the official design documents this includes a very expensive scanner, something that could be replaced in true hacker style with a few salvaged flatbed scanners.
After the break you can chec…

Emulating a student clicker with an Arduino

Emulating a student clicker with an Arduino:

When schools and universities have hundreds of students in a lecture course, they need a way to tell alumni and other potential benefactors that faculty/student relations are just as good as they were in the 1960s, when enrollment was just a fraction of current levels. Technology solves all problems, apparently, so administrators of these universities turn to ‘clickers’ – radio frequency remotes used to take attendance and administer quizzes.These clickers have absolutely no security, so it’s no surprise [Taylor Killian] was able to emulate one of these clickers with an Arduino allowing anyone with a laptop to cheat on a quiz, or have an entire class show up with only one student in the room.
Previously [Travis Goodspeed] (thanks for sending this in, [Travis]) tore apart one of these clickers – a TurningPoint ResponseCard RF – and discovered it uses a Nordic nRF24L01 wireless transceiver, commonly available on eBay for about two dollars.

Controlling a quadcopter with a Leap Motion

Controlling a quadcopter with a Leap Motion:

A few folks over at National Instruments going under the name LabVIEW Hacker have gotten their hands on a Leap Motion dev kit. The Leap is an interesting little input device designed to track fingertips in 3D space, much like a Kinect but at much higher resolution. Needing something to show off their LabVIEW prowess, these guys controlled their office AR Drone with the Leap, making a quadcopter controller that is completely touchless.
Building on their previous AR Drone hack, the LabVIEW team spent the better part of a day adding wrappers around the Leap SDK and adding in control for their RC quadcopter. Now, simply by moving their fingertips over the Leap sensor, they can control their office quadrotor using a very high-resolution 3D scanner.
Video after the break.

Philips L-Prize Bulb

Philips L-Prize Bulb:


This is the best household LED bulb at the moment. It runs on only 10-watts, gives off the light of a 60-watt tungsten, delivers a soft white light, with the even distribution of the old bulbs. It’s dimmable. And it is promised to last 22-years.  I can confirm all these claims except the last (too early to tell). It is exactly the same shape and size of a 60-watt tungsten bulb, which many other LEDs are not. This makes it easy to swap out. Also, this one is brighter than most other LED replacements that I’ve used, including the previously reviewed Lemnis 40-watt LED bulb. It is more energy efficient than other 60-watt LED equivalents. Believe it or not, at $40 it is among the cheaper hi-powered LED bulbs — although the price is still too high for me to swap all my household bulbs (most of which are compact fluorescents).
Beside the price, two minor caveats. The bulb is heavy. It seems to be made of solid ceramic. It may not work in a counter-balanced fixture like …

Samsung to Start Making Bendable Displays for Smartphones in First Half of 2013.


Samsung Display, a producer of display panels that belongs to Samsung, is in the last phase of development of flexible displays for mobile devices, which are expected to be released in the first half of next year, a person familiar with the situation revealed to the Wall Street Journal. Bendable displays are virtually unbreakable and naturally provide a lot of opportunities when it comes to creation of innovation shapes of smartphone.
Even though Samsung has already demonstrated flexible displays and mobile phones at Mobile World Congress trade-show, it does not mean that that the actual devices on their base will be as weird as technology showcases. The main advantage which they will like provide will be added crash-worthiness as well as improved usability. While the screens themselves will be able to bend, other electronics components inside smartphones, such as printed-circuit boards or chips, will not b…

LG Introduces 23" Display with Touch for Windows 8-Based PCs

Image
While I know that Win 8 Works better in a touch-based environment,
I'm not so sure this would be as widely adopted as LG might think.

If it were mounted flush with a desktop surface, it might be useful as a
desktop implementation of a tablet experience....

LG's Touch 10 Display Brings Touchscreen Experience to Desktops



LG Touch 10 is a 23” monitor with touchscreen functionality and 1920*1080 resolution. The display utilizes an in-pane switching (IPS) pane with advanced color and clarity. LG did not release full specs of the new monitor, one should probably expect advanced high performance IPS (AH-IPS) panel with improved colour accuracy and greater light transmission as well as lower power consumption compared to several years-old display. According to LG, the monitor’s setup is hassle-free and the full touch functionality is available as soon as the monitor is connected, no extra software is required.
