Test-approved app could kill off the graphing calculator
Math students have a love-hate relationship with the funky, expensive TI-84 graphing calculators, but thanks to a new deal, they'll soon get a free option. Starting this spring, pupils in 14 US states will be able to use the TI-like Desmos online calculator during standardized testing run by the Smarter Balanced consortium. "We think students shouldn't have to buy this old, underpowered device anymore," Desmos CEO Eli Luberoff told Quartz.
Texas Instruments has a gold-hued graphing calculator
Want to prove that you're a cosine champion at your next math exam? Texas Instruments thinks it has the answer. It's trotting out a limited edition version of the TI-84 Plus CE graphing calculator that comes in a gold-hued (as TI puts it, "Golden Ratio") metallic shell -- yes, you can show some swagger while you're visualizing functions. There's also a special "Bright White" model (below) if you're not quite so ostentatious. Both calculators should arrive this summer without a price premium (existing models sell for $108 on Amazon), so you won't have to pay extra to bring some flash to your calculus class.
TI's super-slim graphing calculator shows that math can be stylish
Who said that graphing calculators were dead in the smartphone era? Certainly not Texas Instruments -- if anything, it's showing that there's still plenty of life left in dedicated math machines. Its new TI-84 Plus CE is 30 percent thinner and 30 percent lighter than the regular Plus, making for a surprisingly sleek-looking way to crunch numbers. It has six times the memory, too, so you can store more color graphs and images (and, let's be honest, a fresh copy of Drugwars for goofing off mid-class). TI hasn't divulged pricing for the Plus CE, although its new design and advanced feature set hint that it'll be relatively costly when it arrives in the spring. Look at it this way, though: you might just be the envy of your fellow students when you take this svelte plotter out of your backpack.
Mod turns your graphing calculator into a selfie camera
Your graphing calculator may not be getting much use these days now that other mobile devices can do the job, but it still has a few tricks up its sleeve if you're willing to do some tinkering. Christopher Mitchell's latest project, ArTICam, lets you turn a TI-83 Plus or TI-84 Plus calculator into a selfie-oriented camera. The mod mostly requires a Game Boy Camera and a programmable Arduino board like the Uno. After a little bit of wiring and some (thankfully ready-made) code, you can snap self-portraits with a calculator command. The 128 x 123 grayscale pictures you take won't win photography awards, but that's not the point -- this is more about having fun with gadgets that might otherwise sit in the closet gathering dust. Hit the source link if you have the gear and want to give ArTICam a whirl. [Thanks, Christopher]
TI-Nspire rethinks the graphing calculator for the iPad (video)
With tablets slowly working their way into the classroom, it wasn't a huge stretch to realize that Texas Instruments would bring a graphing calculator app to the table, but would you believe its solution is just hours away? The company has revealed TI-Nspire for the iPad, which is currently available within the App Store for those in Australia. Beyond problem solving, the product is said to provide an interactive experience that should be helpful for reinforcing mathematical concepts. Depending on your needs and curriculum, you'll find numerical and symbolic (CAS) versions of the TI-Nspire app, both of which cost $29.99. Yes, the app's a bit pricey, but it's not surprising given the insane profit margins of TI's graphing calculator biz. Hop the break for a better peek of the app that might just become required within classrooms.
Unlike the cake, Portal on a TI calculator is not a lie (video)
People have been using scientific calculators as math class distractions for years, from gunning down Nazis in Wolfenstein to hunting demons in Doom. But our jaws dropped in amazement when we discovered that an enterprising fellow that goes by Builderboy from Omnimaga has ported over Portal to the humble number cruncher. Dubbed Portal Prelude, the monochrome game is built only for the TI-83 Plus and TI-84 Plus series of graphing calculators and was based on the Flash clone of the popular video game due to the two-dimensional nature of the platform. Sure, it's not as engaging as the genuine article, but seeing as it's the only portable version of the game we know of, we'll take it. Indeed, you can go ahead and download it right now if you have a compatible calculator. In the meantime, we're eagerly waiting to see how this could be rejiggered to take advantage of the color display of the TI-84+. You can take a peek at the demo video after the break.
Casio's touchscreen graphing calculator arrives in 2013, makes the TI-84+ look dated
Everything's a battleground these days, isn't it? Even the makers of humble graphing calculators can't resist a scrap. Casio is now throwing down the gauntlet, announcing that its fx-CP400 will arrive shortly after rival TI's color-screened TI-84+. Casio's offering comes with a 4.8-inch, 320 x 528, stylus-driven display and can switch from vertical to horizontal modes at the touch of a button. If you're planning on some illicit classroom movie-watching, however, then you should know it only has around 30MB of storage -- but hey, that might be good enough for one thing.
Texas Instruments confirms color TI-84+ calculator is on track for a spring 2013 release
You've seen the recent rumors of a TI-84 calculator with a color screen, and now Tech Powered Math has gotten the official word from Texas Instruments that such a device is indeed coming, finally bringing the popular line of calculators out of the monochrome age. As those earlier reports have suggested, however, you'll have to wait until sometime in the spring of next year to get you hands on one, and pricing has yet to be confirmed -- the site says the MSRP "could" be in the neighborhood of $150, though. Apparently, one reason for the lack of specificity with a release date is that the apps from the older calculators aren't compatible with the new TI-84+ C, so Texas Instruments has been focusing on rewriting the most popular ones in time for the calculator's release, with an eye towards releasing more over the course of the summer. TI assured the site that the new model is "not replacing anything," though, and adds that it has no plans to discontinue the standard TI-84+ or the TI-84+ Silver Edition. Those interested can find plenty more details on the calculator and TI's plans at the source link below.
TI-84 calculator with color screen surfaces, geeks giddy with anticipation
Texas Instrument's TI-84 makes quick work of graphs and equations like nobody's business, but it's done so for years while clinging to an outdated black and white screen. Now, however, it looks like that'll change for at least one flavor of the souped-up digital abacus. Cemetech forum user 0rac343 posted a photo of a TI-84+ C Silver Edition, claiming that it was one of 24 provided by TI for in-classroom testing and that it's slated to launch next spring. Tech Powered Math reports that a contact who's worked with Texas Instruments has confirmed that the calculator is the real McCoy. In fact, the firm's website has a page where visitors can sign up for updates about the number cruncher in question. With the help of the refreshed TI-84, we might finally be able to tell if Blinky, Inky, Pinky or Clyde is the ghost chasing us down in the hardware's Pac-Man clone.
Texas Instruments TI-83 Plus review
The year was 1999. I was pondering all too carefully what kind of threads I'd be wearing come the new school year. But all I could really think about was exactly how much of my styling budget would be blown on some antediluvian piece of technology that -- in my mind -- was no longer necessary due to the invention of the internet. That hunk was Texas Instruments' TI-83 Plus. So far as I could understand it, the "Plus" meant that it had a few extra megabytes of RAM; why you needed loads of RAM in a graphing calculator, I had no idea. At $119.99, it was the most expensive purchase I made leaving middle school, and now that I've had well over a decade to toy with it, it's about time I sat down and gave it a proper review. Join me after the break, won't you?
Google brings graphing calculator functionality to search, still can't play 'Snake'
Well, Google's gone an done it, turning the Internet into one giant graphing calculator. The software behemoth has brought graphing capabilities to search, letting users input a mathematical function into the engine -- or multiple functions, separated by commas. And, this being Google, users can explore the graphs more closely by zooming in and out and panning across. According to the company, it "covers an extensive range of single variable functions including trigonometric, exponential, logarithmic and their compositions." If you know what all of that means, we're guessing you're pretty psyched about this news.
Retro gadget orchestra nails House of the Rising Sun, puts your garage band to shame (video)
YouTube user BD594, also known as James Cochrane, is no stranger to pushing retro tech to its musical limits. Back in 2009 he coaxed a scanner, an Atari 800XL and a host of other antiquated gadgets to perform Bohemian Rhapsody. The results, while certainly enjoyable, were a tad tone deaf. Well, in the years since he's tweaking his "musicians" and his orchestra has just issued its second single -- a stunning rendition of House of the Rising Sun, in the style of the Animals. Seriously, this staple of '60s high school rockstar wannabes is absolutely nailed by the assortment of hard drives, oscilloscopes and the scanner. Cochrane isn't alone in his quest to turn obsolete tech into musical magic. Christopher Mitchell managed to hack a Ti graphing calculator and floppy-disk drive into a monophonic media player. While his accomplishment is impressive, he loses this round for wasting his skills on the saccharin stylings of Cold Play. Check out both videos after the break.
Graphing calculator web browser lets you visit your favorite sine wave fan sites (video)
Graphing calculators: essential tools for math education or low-res Game Boys? The debate rages on. Advocates of non-mathematical applications for the devices have scored a major victory with the introduction of Gossamer, a new web browser for various TI graphing calculators, which lets users visit some very basic versions of webpages, using the CALCnet and globalCALCnet protocols. The 1.0 version can request, display, and scroll pages. Logging in will bring you to a portal with links -- the application's developer has promised to add the ability to directly enter URLs in a future version, however. There's a demo video after the break, though you may want to wait until after math class to check it out.
TI-Nspire CX graphing calculator now shipping, color officially 'in'
It may have been hard to believe when it was announced back in February, but you can rest assured that Texas Instruments' new color TI-Nspire CX calculator is indeed real, and shipping right now. Assuming you're ready to make the jump from monochrome, the $165 asking price will buy you a 3.2-inch 320 x 240 display, 100MB of storage, 64MB of memory, and TI's new version 3.0 operating system that comes complete with 3D graphing capabilities. Of course, TI isn't completely breaking new ground here -- Casio's had a graphing calculator with a "high res" color screen since way back in 2010. [Thanks, Michael]
TI-Nspire graphing calcs get full color displays, 3D, WiFi, and new OS
It's been a good year or so since the TI-Nspire line of graphing calculators got a refresh, but that was nothing compared to what the company's planning for this year. Possibly responding to changing times (or the Casio Prizm), the new Nspire devices are getting a WiFi dongle for communication with TI-Navigator workstations, a 16-bit (320 x 240) full color display, and a number of new functions, including the ability to load images and analyze images for such things as curve fitting functions and regressions. Perhaps even more exciting, the new Nspire OS 3.0 features 3D functions -- and, yes, the original grayscale TI-Nspire models will be able to upgrade to the new OS when it becomes available this spring. Tech Powered Math is reporting a mid-April release date, for an MSRP of $165. Totally psyched? We bet you are! See the PR after the break for more info.
TI-Nspire calculator: yes, it plays Doom
Sure, folks have ported games over to the good ol' number cruncher for ages, but getting a fully rendered classic like Doom to run on a calculator is a different feat altogether. The folks over at omnimaga have successfully moved a beta version of nDoom (a reworked version of the original id Software's FPS) over to a Texas Instruments TI-Nspire and -- with all things considered -- the game runs shockingly smooth. As of right now, the only proof of concept is the video you see above, with a tragic crash bringing all things dangerous to a dismal halt. We're looking forward to a fully working version of nDoom because, you know, video games and calculators are two things close to our nerdy hearts.
Casio debuts Prizm graphing calculator with 'high-res' color screen
Texas Instruments recently rocked the graphing calculator world by adding a touchpad to its TI-Nspire calculator, and Casio has now come back with a technological revolution of its own: a high-res color screen. Of course, a 3.7-inch, 384 X 216 display may not be much by smartphone standards, but Casio insists that the "Blanview" LCD will let equations and text be "displayed just like they appear in textbooks." The rest of the calculator's specs aren't too shabby either, and include USB connectivity, 16MB of flash memory, and a promised 140 hours of battery life. You'll still have to stick to your cold, hard black-and-white world for a while longer, however, as the Prizm won't be available until sometime in January, when it'll set you back $129.99.
DIYer constructs 4.3-inch Open SciCal graphing calculator, puts your TI-83+ to shame
What's 4.3-inches diagonally, costs $200 to build and has absolutely no reception issues when held as shown in the image above? Why, the Open SciCal! Matt Stack, the genius who pieced this gem together, relied on a 1GHz ARM Cortex A8 CPU, 8GB SD card, WiFi module and a spartan web browser in order to concoct what's likely the most desirable graphing calculator this side of Pluto. The handheld device weighs about 1.6 pounds, runs Linux as well as the statistically inclined R, and is reportedly capable of doing roughly twice as much crunching as Texas Instruments' Nspire. Skeptical? Considering that this bad boy sucked down stock data from Yahoo! Finance and ran auto-correlation on the numbers in order to near-instantly report current trends, we're guessing TI (or any other graphing calculator company, really) has no room to argue. Hit the source for more details, and don't worry -- that feeling of insignificance wanes with time.
Ask Engadget: what's the best graphing calculator for under $200?
We know you've got questions, and if you're brave enough to ask the world for answers, here's the outlet to do so. This week's Ask Engadget question is coming to us from Brian, who just can't help but think about the dreaded back-to-school season already. If you're looking to send in an inquiry of your own, drop us a line at ask [at] engadget [dawt] com. "Hello Engadget. I'm currently scouting a calculator for school. What's the best calculator to buy for around $200 dollars?" We're going to guess this guy's majoring in poetry, but those blasted math courses that "they" make everyone take is driving this need. It's funny to think how slowly graphing calculators have evolved (and how prices have fallen at an even more lethargic pace), but there's just got to be something better out in 2010 than the tried-and-true TI-83. Right? Let the man know in comments below.
TI-Nspire graphing calculator gets a new touchpad, nerds swoon world o'er
Texas Instruments has been making graphing calculators for twenty years now, and things look pretty much the same as they were in that bygone era of Amy Grant and C&C Music Factory. The company's latest, TI-Nspire with Touchpad, features -- you guessed it! -- a touchpad above the keypad for scrollin' around, as well as a letterpad (apparently they had to forgo QWERTY to make this compliant with tests like SAT and ACT). And, like its precursors, it comes with a snap-in TI-84 Plus keypad so your old dog won't have to learn any keystrokes. Available now from your fave e-tailer, look to pay around $140.
