Air-Blowing Robot Makes Ping-Pong Balls Jump Through Hoops

Sure, you can make a ping-pong ball float just by blowing at it through a drinking-straw, but wouldn’t a ball-levitating robot be so much more fun? Luckily for us, University of Illinois grad students Aaron Becker and Robert Sandheinrich answered “yes” to this question, and built this incredible machine:

It’s called the Robo-Air Blower, and while the principle is pretty simple, the physics behind it are complex. A gimbaled nozzle fires compressed air at 620 kPa of pressure. This jet creates a fast-moving, low pressure area around the ball, trapping it. The jet is powerful enough to lift balls of between 24mm and 194mm in diameter, and up to 188-grams of mass.

But the tricky part is control. Fluid dynamics are a chaotic thing, and the programming of the robot control multiple balls, as well as non-spherical objects, like the water-bottle in the video, is complex. The robot’s brain is fed by two stereo cameras which track the balls’ movements and adjust the jet based on an algorithm.

Despite this somewhat dry explanation, the results are spectacular. The robot can push the balls sideways and diagonally, and make them jump through hoops. It looks like some kind of iPhone or Android video-game brought to life, or an up-to-date version of the old loop-and-live-wire game we played in school.

Pen Clip Clips Pens to Moleskine Notebooks

You got a brand new Moleskine notebook or diary for Christmas. You also got a fancy new pen. And if you’re really lucky, Uncle Pete gave you just over $13 (or €10) to spend on anything you like. Generous old Uncle Pete.

Might we suggest you pick up the Pen Clip, designed for Authentics by Stefan Diez. It’s a metal tube that clips into the spine of a notebook and lets you slide in any pen, be it a write-anywhere space-pen, or a cheap-o Biro. It’s a handsome way to keep pen and paper together.

It will be useless, of course, if your pen already has a clip (clipped pens can be forced into the Moleskine’s spine, like an epidural into a human’s vertebrae, but the spine will crack after a while). The Pen Clip can also be clipped to posters, calendars and anything else.

The $13 is for the small sized clip. If you received a large pen for your gift, then you’re out of luck: the large clip costs €13, or $17. Uncle Pete doesn’t look so generous now, does he?

Video of Google Earth 4.3 in Action

This article was written on April 16, 2008 by CyberNet.

Yesterday we quickly mentioned that Google was set to launch Google Earth 4.3 sometime in the evening and we outlined some of the features that it was going to have. The new version has launched and now that we’ve seen it in action, we decided more needed to be said. Google has really done an amazing job with this version, particularly with the lighting effects, the new navigational gadgets, and the way they implemented Street View.

The Google Earth Blog put together a great video which demonstrates these features, so if you want to see what it’s all about but you don’t want to download Google Earth quite yet, definitely take a look.

If you go to about 8 seconds into the video, you’ll see a great demo of the lighting effects which allow you to see the current position of the sun. You can drag the time slider back and forth to see how the sun progresses across the Earth. Zooming into the Earth will allow you to see the effects of the sun on the terrain.

Another great section of the video goes over Street View which does work different in Google Earth compared to Google Maps. You’ll find that section at about 3 minutes and five seconds into the video.

Take a look, I think you’ll be impressed!

Nintendo 3DS escapes production line, strikes a pose with Yoshi

No, not that Yoshi, but the real, officially licensed critter with a penchant for chomping Goombas and dropping eggs. Nintendo’s 3DS handheld has, according to 3DS Buzz, been stolen from a Chinese manufacturing factory and leaked all over the Internet. This version is a little different than what we saw at E3 and even the “official” version from the September 29th announcement, the Select, Home, and Start buttons having been made flush into the screen bezel. Also, a 1300mAh battery is confirmed, as is 96MB of RAM. We have another picture of it below, showing it’s size compared to everything from a Game Boy Micro to a DSi XL, nicely demonstrating that Nintendo’s new hotness is a little bit smaller than even a standard DSi. That’s progress for ya, folks.

Update: David T. wrote in with a video of the thing in action — well, in non-action, really. It’s embedded below, and as you can see the poor backless 3DS is decidedly non-functional.

Nexus S overclocked to 1.2GHz, runs too damn fast for its Bluetooth to work

Even at its default 1GHz speed, Samsung’s Hummingbird is one of the finest mobile processor around, but are you really going to complain about getting the option to crank an extra 200 milion clock cycles out of it? Morfic over on the xda-developers forums has delivered a kernel permitting Nexus S owners to achieve just that, although he still has to fix an issue that disables the phone’s Bluetooth capabilities.Still, if you value ludicrous speed over wireless peripherals, the source link is your friend.

Apple’s New Year’s Resolution Should Be to Fix the iPhone Alarm

As the new year was rung in, iPhone alarms remained curiously silent.

Apple has confirmed an iOS bug that left the iPhone without functioning alarms on the first of January. Multiple tests on the iPhone alarm showed that it failed to go off when the digital calendar rolled over from Dec. 31, 2010 to Jan 1, 2011.

Apple spokesperson Natalie Harrison told Macworld that the the bug had been officially recognized, and would fix itself on Jan. 3.

“We’re aware of an issue related to non-repeating alarms set for Jan. 1 or 2,” Harrison said. “Customers can set recurring alarms for those dates and all alarms will work properly beginning Jan. 3.”

However, some iPhone customers in Asia and Europe said they were still experiencing alarm malfunctions as of Jan. 3, according to Reuters. Also, some U.S. customers said on Twitter this morning that their alarms weren’t working.

“This is why I missed the gym this morning,” tweeted Rik Nemanick, a Saint Louis resident.

Apple claims the alarm issue has only affected non-repeating alarms — meaning if your alarm is set to go off at the same time “every Monday,” for example, it should have worked today. However, for those who set a one-time alarm for this morning, some may have experienced the malfunction.

If you’re paranoid about sleeping in late, the quick fix for the issue is to set recurring alarms. To set repeating alarms, launch the Clock app, hit the + sign to create an alarm, then tap Repeat and choose the day(s) you want this alarm to go off regularly.

The alarm code in iOS seems to be pretty buggy. This latest problem follows a bug that caused alarms to sound an hour late when both Europe and the United States flipped over from daylight saving time at the end of the summer.

An unreliable alarm clock is a frivolous bug, but it’s particularly embarrassing for Apple, a company that prides itself for fine details of its products. Here’s hoping that Apple issues a complete rewrite of its clock app whenever it releases the next iPad or iPhone.

Today is the third, and judging by the fact that The Lady made it out of the house on time this morning, iPod Touch alarms are working fine. On the other hand, she has a curious habit of leaving recurring alarms running on my iPod Touch, waking me at all sorts of odd hours, so it could be that.

iRobot unveils super-compact Scooba 230, new Roomba 700 series

Our friends at iRobot have shrunken its hardwood cleaning child — not Roomba, the other one — to about half the diameter of its predecessors (6.5 inches). The Scooba 230 is maintains the same 3.5-inch height and, more importantly, is just as programmable as every other model (in an unfortunate twist of irony, it’s now thinner than a Kinect sensor). Speaking of Roomba, the company’s also unveiling the new 700 series with a number of cleaning and detection improvements. All autonomous cleaning discs will be available in the Sprint from iRobot’s online store with the prices ranging from a penny under $300 for Scooba 230 and $450 / $500 / $550 for the Roomba 760, 770, and 780.

Samsung reaches goal: 10 million Galaxy S phones sold worldwide

Can’t say we’re surprised — after all, last time we checked in the tally was hovering around 9.3 million — but now Samsung has officially met its goal of 10 million Galaxy S phones sold around the globe. That’s less than seven months since the device first hit the market, which by Sammy’s fuzzy math averages to about one unit for every two seconds it’s been on sale. According to Samsung Tomorrow, North America contributed the most with 4 million in sales, followed by Europe at 2.5 million. Let there be cake, and once that’s over, let there be progress on those Froyo updates.
