Make: Arduino — Hooking up a 7-Segment LED Display

Posted: 10 Mar 2011 03:01 PM PST


As part of our Make: Arduino page, Riley Porter has posted a project that shows you how easy it is hook up a 7-segment LED display to your Arduino projects. This is the first, simplest method he explores. In a future project, he’ll show you more elegant solutions that don’t hog so many I/O pins.

And as with the RFID Reader project Riley posted, this is really a project stub. We’re hoping others who have used such displays on their ‘Duino projects will add their experiences, tips, images, etc. to the project. Make: Projects are living documents. Help them grow!

How Big Data Justifies Mining Your Social Data

Posted: 10 Mar 2011 02:52 PM PST

GMGruman writes "Paul Krill reports that one of the big uses of the new "Big Data" analytics technology is to mine the information people post through social networking. Which led him to ask 'What gives Twitter, Facebook, et al. the right to mine that data?' It turns out, users do when they sign up for social networking services, even if they don't realize that — but less clear is the ownership of other information on the Web that these tools also mine."

A Barbecue You Can Sling Over Your Shoulder [Desired]

Posted: 10 Mar 2011 02:40 PM PST

I pretty much hate the beach, the woods, or anywhere else I'd have use for a portable barbecue, but I love this Element grill by Fuego, not only for it's folding design, but because it still looks really, really good. The gas-powered grill puts out 8,000 BTUs, and weighs less than 15 pounds. When you're not using the grill, it has a big rubber band that holds everything in place, also giving it a bit of visual flare. The Fuego Element will cost $150 when it starts shipping on March 28.

How to solve iOS 4.3 syncing issues

Posted: 10 Mar 2011 02:30 PM PST

iOS 4.3 software update

If you're having issues syncing your iPhone, iPad or iPod touch after updating it to iOS 4.3, this tip is for you. It turns out that many people have seen a bug where, after updating any iDevice to the latest version of iOS, syncing with iTunes will stall at step four of four on syncing photos. The stalling is accompanied by a message that the sync could not be completed because "the required file cannot be found". Does this sound familiar?

Well, it turns out that the solution to this bug, that apparently keeps intermittently appearing, is quite simple -- if rather time-consuming. The culprit for this particular issue is your photo library. And the way to fix it is to uncheck photo syncing in iTunes, then sync. Afterwards, check photo syncing, and sync again. This will cause the second sync to take a long while if you have many photos in your library, since iTunes needs to re-optimize your photos and copy them back to your iDevice. However, it does work.

Microsoft taking 'extra time' to make sure Windows Phone 7 copy and paste update is solid, targeting late March

Posted: 10 Mar 2011 02:12 PM PST

Eric Hautala -- the cog in the Microsoft machine responsible for Windows Phone 7's update mechanism -- has taken to the company's official Windows Phone blog today to deep-dive on some of the concerns, problems, and delays that have dogged the platform's updates so far. In brief, Hautala says that the glitches that hosed the small February update for a few customers has brought the company to pause and take the time to make sure everything's rock solid before proceeding with the so-called NoDo update -- which includes copy and paste, performance improvements, and CDMA support -- and had originally been scheduled for the early part of March. Now, they're looking at "the latter half of March," which lines up with what Microsoft France had reported yesterday. He goes on to say that the problems have zero effect on the timeline for awesome new features previewed at MWC last month, which would seem to allay fears that the Mango update had been pushed to 2012. Needless to say, Windows Phone's still got some catching up to do -- so that's good news.

Ask Slashdot: Data-Only Phone, Voice Over WiFi?

Posted: 10 Mar 2011 02:01 PM PST

enFi writes "I want to pay one ISP (only!) for data (only!), and use it for my smartphone and my computer; and until they catch up, I want not to inconvenience the rest of the world — still let them call a phone number. (We all want this, right?) I'm most of the way there: my plan is to get a Clear Spot (their 4G WiMAX coverage is good for me) to use with my unlocked Nexus S (which will only ever use WiFi). I could just use Skype and an Online Number, but talk of Sipdroid+pbxes.org+GV and the recent Google Voice / SIP article make me think I'm only starting to untangle the mess of services and options. Is there a good (not to mention best) way to do this?"
