TI-84+C-Silver Edition: That C Stands For Color

December 19th, 2012 12:32 admin View Comments


skade88 writes “Do you remember those large TI-8X line of calculators with a BW display from when you were growing up and learning all about math? Yeah well, you can still get them because TI has yet to update or change their line of TI-8X calculators from their 96×64 display, processors designed in the 1980s with just a few kilobytes of user accessible memory. They still cost in the $100.00 to $150.00 range. That is all about to change now that the TI-8X line of calculators is 22 years old. Their new TI-84+C-Silver edition will come with a 320×240 16-bit color display, 3.5MB of flash ROM, and 21KB of RAM. Ars has a good preview of the device along with speculation on why it took so so so very long for TI to finally bring calculators up to a level of technology that could have been delivered a decade ago.”Last month some photos and a few details of the new TI-84+C were leaked.

HP Sues Over LCD Price Fixing

December 4th, 2012 12:21 admin View Comments


angry tapir writes “Hewlett-Packard has filed a complaint against display manufacturers Chunghwa Picture Tubes and Tatung Company of America, seeking to recover damages it claims it suffered as a result of their involvement in a price fixing scheme. In November 2008, Chunghwa pleaded guilty to participating in a conspiracy together with other display manufacturers, including LG Display and Sharp, to set the prices of Thin-Film Transistor-Liquid Crystal Display (TFT-LCD) panels to predetermined levels. The company agreed to pay a US$65 million criminal fine at the time. A jury found AU Optronics, another display manufacturer, guilty of participating in the same conspiracy and was fined US$500 million in September by a judge of the U.S District Court for the Northern District of California. In October last year, 10 LCD makers, including Chunghwa Picture Tubes, were fined $176 million in South Korea for allegedly holding secret meetings to keep the prices for flat screen displays artificially high.”

Kickstarted Oculus Rift VR Headset Shipping In March/April

November 28th, 2012 11:05 admin View Comments


An anonymous reader writes “After an amazing Kickstarter campaign garnering over $2.4M in backing, VR headset Manufacture OculusVR has announced manufacturing details and also a shipping delay until March or April 2013. Oculus says that due to the number of backers, mass manufacturing would be required. ‘All together, preparing the factory for mass production of a product like the Rift takes approximately 90 days and the factory can’t begin until design and feature set has been locked down. Our manufacturer is already underway with the first tooling (T1), which takes roughly 50-70 days. Once the primary tooling is complete, we’ll do a series of pilot runs for minor tweaks and adjustments before mass production. Simultaneously, we’ll be testing and certifying the device for public use.’ Additional details are included on their 1000hz 9DOF head tracker and 7″ screen: ‘Ultimately, we selected a modern, 1280×800 7’’ display for the developer kit. The bright side is that the new display beats the old display in almost every key area including response time, switching time, contrast, and color quality. The improved switching time of the panel actually alleviates most of the motion blur people saw in earlier prototype demos. The downside to our new 7’’ is the weight differential: approximately 30g more than the 5.6″.’ It looks like the VR revolution will have to wait a little bit longer.”

The Explosive Growth of 3D Printing

October 1st, 2012 10:17 admin View Comments


MojoKid writes “If you’ve ever attended a World Maker Faire, the first thing that strikes you is how organic the whole scene is. Inventors, creators, and engineers from all walks of life have their gadgets, science projects, and creations on display for all to see. Some of the creations you see on display range from downright amazing to completely bizarre. One of the big attractions, a technology area that has experienced explosive growth, is the land of 3D Printing. MakerBot took the open source RepRap 3D replicator project mainstream back in 2009 with the release of the Cup Cake CNC machine, then came the Thing-o-Matic and then a little bot called Replicator. With each iteration, improvements in process and technology are bringing better, more capable 3D printers to market, from MakerBot’s new Replicator 2, to new players in the field like Solidoodle, Up!3D, Ultimaker, and Tinkerines. To watch a 3D printer in action is like witnessing art, science and engineering all working together in glorious unison.”

CowboyRobot writes “Dr. Dobb’s reviews an alternative to Google Glass and goes through the steps of coding your own Android-based Heads-Up Display. ‘By tucking their 428×240 pixel WQVGA heads-up display in the lower right corner of ski goggles, Recon has effectively created an unobtrusive HUD with a decent 600 MHz ARM Cortex A8 processor running Android 2.3.3 (Eclair). Network connections can be made via a Bluetooth-paired Android smartphone.’”

Thoughts On the iPad Mini

August 15th, 2012 08:12 admin View Comments


John Gruber at Daring Fireball has a thoughtful piece about the design of Apple’s smaller iPad, which the company is expected to announce on September 12. Simply shrinking the current iPad’s dimensions to a new form factor is unlikely, he says, and the bezel surrounding the display is more likely to be a cross between an iPad and an iPhone. He also discusses evidence of Apple’s PR team getting the rumor mill going immediately after the announcement of Google’s Nexus 7, and how Apple has probably bet on having a thinner and lighter tablet than Google, rather than worrying about a better display. Quoting: “Apple product designs are true to themselves. Each thing has proportions suited to its own nature. Consider how the iPad doesn’t look like a blown up iPhone. They share a few similar design elements — a family resemblance, if you will — but the proportions are different. The iPad has a thick bezel surrounding all four sides of the display; the iPhone does not. Why? Because you need a place to rest your thumbs while holding an iPad. … Should not the iPad Mini fall somewhere in between? Not as close to the aspect ratio of its display as the iPad-as-we-know-it, but also not as far away from its display aspect ratio as the iPhone. You might need more thumb-rest room on the sides than you do on the iPhone, but not nearly as much as you do on the full-size iPad. If that assumption is right, the proportions of a 7.85-inch 4:3-aspect-ratio display iPad Mini are likely not the same as the proportions of the 9.7-inch 4:3-aspect-ratio display iPad.”

MIT Develops Holographic, Glasses-Free 3D TV

July 12th, 2012 07:10 admin View Comments


MrSeb writes “Engineers at the Massachusetts Institute of Technology (MIT) are busy working on a type of 3D display capable of presenting a 3D image without eye gear. What you’ve been presented with at your local cinema (with 3D glasses) or on your Nintendo 3DS console (with your naked eye) pales in comparison to what these guys and gals are trying to develop: a truly immersive 3D experience, not unlike a hologram, that changes perspective as you move around. The project is called High Rank 3D (HR3D). To begin with, HR3D involved a sandwich of two LCD displays, and advanced algorithms for generating top and bottom images that change with varying perspectives. With literally hundreds of perspectives needed to accommodate a moving viewer, maintaining a realistic 3D illusion would require a display with a 1,000Hz refresh rate. To get around this issue, the MIT team introduced a third LCD screen to the mix. This third layer brings the refresh rate requirement down to a much more manageable 360Hz — almost within range of commercially produced LCD panels.”

Asus Joins High Density Display Club With New Transformer Tablet

June 25th, 2012 06:05 admin View Comments


crookedvulture writes “The new iPad has received a lot of attention for its high-density display, but it’s not the only tablet with extra pixels. Enter Asus’ Transformer Prime Infinity, which has a 10.1″ screen with a 1920×1200 resolution. The display doesn’t look as good as the iPad’s Retina panel, which has crisper text and better color reproduction. However, the Android-based Transformer has perks the iPad lacks, like an ultra-bright backlight, a Micro HDMI port, a microSD slot, and more internal storage. The Infinity is also compatible with an optional keyboard dock that adds six hours of battery life, a touchpad, a full-sized SD slot, and a standard USB port. The Transformer’s tablet component is definitely no iPad-killer. When combined with the dock, though, the resulting hybrid offers a much more flexible computing platform.”

Web Developers Brace For the MacBook Pro’s Retina Display

June 25th, 2012 06:01 admin View Comments

The Web is about to get uglier – that is, if you’re eager enough to plunk down $2,200 for the new MacBook Pro with its ultra high-resolution “retina” display. The new laptop, which Apple unveiled last week, already has Web designers and developers trying to figure out how they’re going to create sites and Web apps that look good on the new machine without leaving the rest of the Web’s population behind.

Graphics and Typography Need to Change

At the heart of the issue are graphics. The backgrounds, buttons, banners and gradients peppered across the Web were created with a certain maximum resolution in mind. As hardware evolves, so too must the Web itself. 

It’s one thing for iOS developers to update their apps for retina devices such as the iPhone 4 or the newest iPad. The desktop, however, is a much more open, mature environment, with software created well outside of Apple’s guidelines. Then there’s the Web. It’s much older and bigger than the iOS ecosystem, which may lead to user experience issues and challenges for developers.

As soon as Apple announced the new MacBook Pro, the designers and developers at the mobile strategy firm Fueled started brainstorming about how this might affect their work.

“There’s a lot of interesting concerns,” says Fueled Director Ryan Matzner. “One is that a lot of screens aren’t going to be retina anytime soon, so we still need to worry about those guys. How do you serve images or graphics?”

Another issue, as Fueled designer Rob Palmer points out, is typography. One of the key advantages of these high-resolution displays is their crisp, highly readable rendering of text. That particular buck stops with the Web browsers, which are much more varied on the desktop than on mobile devices. Naturally, Safari supports retina-friendly text, but Chrome is still working on it, and other browsers will presumably follow.

Balancing Beauty and Page Loading Time

Creating bigger graphics is easy enough, but that raises a new issue: increased page load times. Outside of audio and video files, images are already among the largest assets a Web browser has to call up when loading a Web page. For image-heavy sites, swapping out higher-resolution images can have a substantial impact on page load, which in turn affects user experience and even search engine rankings. 

To deal with this issue, Web developers can borrow from some of their tried-and-true methods. For years, websites have used browser detection to deliver different CSS stylesheets to different browsers. A similar approach is used to craft responsive designs – when sites load different layouts depending on the device being used to view it. Likewise, this sort of tactic could be used to handle graphics, Matzner says. 

That’s exactly what they’re doing at O3 World, an interactive agency based in Philadelphia. To account for different screen resolutions, they’ve begun creating multiple sets of graphics, which are delivered dynamically, depending on the user’s screen resolution.

“This takes additional time from a planning and development standpoint and also from a QA point of view,” says Michael Gadsby, creative director at O3 World. “This in turn hits the client from a cost perspective.”

All of this thinking and planning is, for the most part, pre-emptive. The MacBook Pro with Retina display has barely begun to ship and isn’t exactly priced or even intended for widespread adoption. Still, this won’t be the last Apple device to launch with a retina display, and the company’s competitors are watching closely.
