Wi-Fi Extending Robot: Not the Hero We Deserve, But the One We Need

A group of students from Boston’s Northeastern University have built a robot that should become every gadget lover’s best bud. Why? Because this unnamed hero is a mobile Wi-Fi hotspot. It can even extend its network by dropping wireless repeaters.

We have Glen Chiacchieri and “seven other computer and electrical engineers” to thank for designing and building the robot. Except for its treads, all of the robot’s parts were custom made from aluminum. It’s quite tough; as you’ll see in the video below it can even ferry an adult human. But adult men can’t connect you to Facebook and Twitter, so Chiacchieri and company installed a router on it instead, along with a webcam, a GPS module and two routers converted to repeaters.  The robot can be controlled on the very network that it deploys, using a web interface that Chiacchieri coded.

All that’s missing is a USB charger and a six pack of your favorite beverage, and that’s good enough to be called Man’s Best Friend 2.0. I highly recommend that you read Chiacchieri’s blog post to learn more about the project and the robot’s capabilities. He does swear quite a lot in the post, so be warned. Although I would too if I built something this awesome. I wonder if these engineers can build a drone version of the robot.

DIY Google Glasses Provide Translation via Subtitles

The first time we featured programmer Will Powell, we learned how he was able to make a crude version of Google’s Project Glass augmented reality glasses. It turns out that Powell has made another version of his hack that is capable of translating spoken language and displaying the translation in subtitles.

project glass translator will powell

Like with his earlier project, Powell used a pair of Vuzix STAR 1200 glasses as the base of the hack. If I understood what Powell said on his blog, a Jawbone Bluetooth microphone picks up the audio and sends it to a mobile device, which then processes the words using translation API made by Microsoft. The translation is then passed on to a Raspberry Pi, which sends a text of the translation to the Vuzix display and a transcript of the conversation taking place to a TV. Below is a shot of the subtitle being displayed on the glasses’ monitor:

And here’s a shot of the transcript on the TV:

Finally here’s a demo of the hack in action. Note that there is a significant delay in the translation, which according to Powell occurs mainly when the audio goes through the translation API.

The sheer number of gadgets needed plus the fact that the Raspberry Pi is physically connected to the glasses via an S-video connector means that this is not a portable system, but I am still amazed at what one man armed with off the shelf parts can do. Besides, all devices – including the ones Powell needs – get more powerful and smaller in time. The time when we’ll be able to reenact Casa de mi Padre is closer than we think.

Trash Can Chases After Garbage, Renders an Office Game Obsolete

If you thought the remote-controlled trash can was neat, wait ’til you see this ingenious invention. It actually catches anything you throw in its vicinity, aim be damned. It wasn’t made in Soviet Russia though – this one’s a Japanese hack.

robot kinect trash can

You can skip to about 2:24 in the video below to see the trash can in action, but I suggest you watch the entire video to see how it “works.” Apparently the trash can is equipped with three wheels that can be wirelessly controlled or activated. A custom program uses a Kinect to detect the path of a thrown object in order to activate and direct the wheels. I have to say that this is all conjecture on my part. For all we know this could be just like the Wipeout toy video, which was awesome but fake.

That looks sooo much fun to play with. I hope this is legit and someone makes a retail version of it. It did make me realize one more thing – robot athletes will be boring, because they’ll be perfect. Imagine a game of baseball with accuracy like this.

London Eye to Become Giant Twitter Sentiment Meter

I’ve always thought one the most interesting landmarks in England was the London Eye. I would call it a ferris wheel, as I think most people from the US would, but it’s simply known as the Eye in the UK. A former British Olympic athlete named Daley Thompson has come up with a plan to help use the massive ferris wheel to promote the London Olympic Games kicking off soon.

london eye

Working with EDF Energy, the wheel’s sponsor, an algorithm will sort through positive and negative tweets sent with the tag #Energy2012. The wheel will be lit up depending on the portion of positive comments sent with the tag. The algorithm was designed by experts on sentiment analysis. For example, if 75% of the tweets are positive, 75% of the wheel will be lit. The more positivity, the more lights.

The wheel will also be lit up in various color patterns to celebrate major sporting moments of the day. If you want help control how much of the massive wheel is lit, you need to start tweeting when the games kick off. The last show will be held each night at 2100 BST that the Olympics are underway.

Embedding an RFID Transit Card Inside Your iPhone

After seeing Dhani Sutanto from London embedding a RFID Transit Card into a ring, Becky from Adafruit thought that it would be a cool idea to try and embed one into her iPhone.

The process is pretty straightforward. First, you need to dissolve away the plastic of the card in acetone. Then you need to extract the antenna and chip. This needs to be installed under the iPhone backplate. You’ll probably have to experiment with paper and tape in order to insulate the chip from the guts of your phone.

The result is that you can carry around your transit card without actually carrying around your transit card. Of course, as NFC technology continues to come along, chances are that someday you’ll be able to pay for public transit just by holding your phone up to the reader anyhow. But for now, this is a clever hack and works with today’s systems.

Gauntlet Keyboard: Your Hand is the Keyboard

A team of young engineers have invented a wearable keyboard. They’re calling it the G.A.U.N.T.L.E.T. – the Generally Accessible Universal Nomadic Tactile Low-power Electronic Typist. I can’t decide which is more awkward, the acronym or the G.A.U.N.T.L.E.T. itself.

gauntlet keyboard

The glove was conceptualized by Jiake Liu, who was inspired by sci-fi movies Children of Men and Minority Report. The glove pairs with devices via Bluetooth, which makes it convenient. What doesn’t make it convenient is the position of the letters, which are scattered all over the glove.

It appears that Liu and his peers invented G.A.U.N.T.L.E.T. as part of a school project, so even though the device itself isn’t that practical I am still thoroughly impressed. Liu imagines a future where the glove can be used to operate almost any device: “Need to microwave something? Touch the microwave oven with GAUNTLET (version 10), and through NFC (near field communication) you are paired with the oven, whose interface will pop up on your glasses, and you can use GAUNTLET to set the cook time.  Need to print something? Touch the printer, and now you can control the printer. Etc.” But if you need to type something? Stick with your phone’s keyboard.

Zorro Macsk Adds Touch Capability to iMac: Rapier Stylus Not Included

With Lion and the upcoming Mountain Lion operating systems, Apple is continuously integrating features from its mobile OS to the desktop experience. Does it mean that a touchscreen iMac is a good idea? I still don’t think so, but you can decide for yourself with the help of the Zorro Macsk attachment.

zorro macsk imac touchscreen

The Zorro Macsk is a frame that is placed over the iMac and plugs in via USB. It has no screen of its own, rather it uses infrared sensors to detect input. While it won’t turn your computer into an expert swordsman, it does support the same multitouch gestures that you can pull off on the Magic Trackpad, so it is a bit practical.

I think it’s nice to be able to use it to switch between Spaces, but other than that I don’t see any great benefit for a touchscreen iMac, unless you happen to like the look of greasy fingerprints on your screen. The Zorro Macsk is currently only available for the 21.5″ iMac., and you can order it on Amazon for $199 (USD).


Ben Heck’s Raspberry Pi Keyboard Computer: BBC Micro-inspired, DIY All the Way

Do you love 80s computer tech? Well then you’ll love Ben Heck’s BBC Micro-inspired Raspberry Pi keyboard computer. He managed to put the $35 DIY Raspberry Pi computer into a nice keyboard that definitely has some retro style.

Ben Heck thinks that the possibilities with the diminutive Raspberry Pi are endless. His keyboard computer features a vintage enclosure, cartridge slots and an add-on experimenter kit. The keyboard has a lot of wood in it, which comes as no surprise. The retro keyboard computer opens up like a desk drawer when the keyboard is lifted up. It’s possible to add an on/off switch, Ethernet connectivity, video/audio composite, DC 5V input and a USB hub. C++ programming was implemented to run tests via the experimentation kit.

iPhone 4S Wireless Charging Mod Goes Well With Wireless Syncing

Even though I’m not a fan of current wireless charging technology, I’m still impressed by YouTuber tanv28, who modified his iPhone 4S to support wireless charging. Pair this with the wireless syncing feature in iOS 5 and you can ditch your charge and sync cables. If you can pull off the mod, that is.

As tanv28 warns in the video, this is not an easy project and it will void your warranty. Such is the price of convenience. You’ll need soldering tools, a thin gauge wire, a spare charger port assembly, a spare iPhone 4S back cover and the wireless charging receiver and circuitry from Powermat. You can skip to about 1:00 in the video for the steps:

Proof that Apple runs in his blood, tanv28 even made a commercial for his customized iPhone:

Tanv28 didn’t mention if his iPhone can’t be charged via a cable anymore, but judging from his thorough guide I’m betting that it the dock connector still works, otherwise he would’ve mentioned it. Now all he needs to do is make his iPhone float.

White Silence PC Casemod Wants to Suck Your Blood

We’ve featured some crazy casemods here over the years, but I can honestly say this is the first one I’ve seen that has blood coursing through its veins. Ok, there’s not actual human blood flowing through the cooling lines of this PC, but it’s still pretty awesome.

vampire pc 1

The White Silence casemod features a stark white case with clean modern lines, accented by cooling lines filled with blood red fluid and matching red cables. Of course, not all of the blood could be contained, and a bit of it has splattered into the case, for an extra gory effect. If Dexter Morgan had a PC instead of a Mac, this would be his computer. Well, the Authority on True Blood could always go for it.

vampire pc 3

It turns out the system was built about two years ago, so under the hood is a Core i7 920, a GeForce GTX 295, 6GB of DDR3-1333 RAM and plentiful storage, with two 500GB Samsung SpinPoint drives, two 150GB VelociRaptor drives, and an 80GB Intel SSD.
