Graphene Antennas to Increase Wifi Performance
Science has given us this substance known as graphene which is far too technical to understand for us laymen. It’s essentially a sheet of pure carbon 1 atom thick. So what does it have to do with wifi performance? Well, according to Dr. Ian F. Akyildiz, director of the Broadband Wireless Networking Lab at Georgia Tech, quite a bit.
His group is working on making wireless router antennas out of graphene which they claim can move electrons with almost no resistance; 50–500 times faster than silicon. According to their calculations, at a range of about 1 meter graphene antennas can shepherd data wirelessly at 1 terabit per second. And at a few centimeters? A whopping 100 terabits per second.
The challenge? Manufacturing. They note that when graphene comes into contact with other materials its properties change.
So the logistics are a little sticky, but the concept is pretty awesome. Good luck, Ian and team. Bring on the data-transfer heat!

Information Society’s Secret Encoded Song
This is an absolutely fascinating story of advanced technology.

In 1988 the band Information Society released their record “Peace and Love, Inc.” which afforded the 80s with one of its more popular songs, “What’s on Your Mind (Pure Energy).” The final track on the record, “300bps N, 8, 1 (Terminal Mode or Ascii Download),” which sounded like silly noise to most people, was actually an encoded text file that could be accessed by following the song title’s instructions:
- Configure a 300 baud modem to no parity, 8 data bits, 1 stop bit.
- Use a telephone to dial into the track.
- Play it through the phone, which in turn plays the track into the modem then the computer.
This is a very arduous process for most people. And those with the knowledge and patience to complete the task would, today, have to find a modem in an attic or antique-electronics website. Thankfully for the curious, the nameless mystery (wo)man over at Noise Made Me Do It dirtied his/her hands and tapped into the file. Following is my cleaned up version of his/her transcription. The story, while likely fabricated or at least highly-elaborate, is entertaining all the same.
So we’re supposed to play in Curitiba in 18 hours, but our bus is being held hostage by the local promoters. They’ve formed some unholy alliance with the Brazilian counterpart of ASCAP:,the PRS. Recently the PRS has the legal power to arrest people, and they want a piece of the national tour promoter’s money. The local security force, “Gang Mexicana,” has been bought out for 180 Zados and a carton of marlboros each. The only faction still operating in our defense is “Big John,” our personal security man, and he’s hiding in his room because a local gang is out for his blood because of a 1982 knifing incident in which he was involved. Our 345-pound road manager, rick only had this to say “you wanted the life of a rock star!” Paul, Jim and I real That this was one situation we were going to have to get out of ourselves.
We convened a hasty conference in the hotel lobby. Paul suggested contacting our national tour promoter in São Paulo, but we remembered that he was in Recife with Faith No More, who had just arrived For their Brazilian tour. We thought about contacting our Brazilian record company in Rio, but they weren’t home. Our ever-diligent American manager was arranging help of numerous forms, but he was in new york, and just too far away to get anything moving in time.
And there were 6000 kids in Curitiba who just wouldn’t understand.
We knew it was time for action. Paul went up to the PRS guys and invited them into the bar to discuss it like civilized men over a few Brazilian drinks, offering each of them a cigar on his way. Amused PRS heavies seemed to like the idea of a few free drinks, even if they knew they would never give us our bus back. When Paul winked at Jim and I on his way in, we went into action.
I stole off to my room to prepare while Jim went into action. Creeping carefully through a service duct, he managed to gain a vantage point some three meters above the bus, and dropped carefully the roof. After using his all-purpose swiss army knife (affectionately known as the “skit knife”) to jimmy open the roof hatch, he went through the darkened inside of the bus and removed the inside engine service panel. Using some spare electronic parts he found while on an island in the amazon, he wired the entire bus for remote control, not unlike a remote control toy car.
At this point, he asked himself “now how shall I get out of here?!?”
Paul was having difficulties of his own. “Couldn’t you see your way clear to letting us fulfill our contractual obligations in Curitiba? Think of the kids!”
Through our translator, Fabio, the PRS man, Aldo, said “no, you Americans think you own the world. Hah! We’ll burn down our rain forest if we damn well please. We need room for cows!! We want a McDonald’s on every…oh, sorry, yes anyway, no. Ed 40% of your concert receipts to give to david bowie,” he said, winking to the local promoter, Phillipe.
As Paul continued this elaborate distraction, Jim effected an escape from the heavily guarded bus by crawling down into the cargo bay, cutting a hole in the floor with the swiss army knife, slipping into the manhole cover situated under the bus, and walking up to the hotel’s basement from there. Jim called up to me in my room and gave the signal. We were now to meet at the Bac Rance, with our tech guys. But first, Paul would need some help getting away from his unwelcome guests, as things were getting ugly.
“He says he has lost his patience, and that he can think of other ways of extracting payment from you Kurt and Jim physically,” our trembling interpreter said.
The moment had come. Jim began operating the bus from his back entrance vantage point. As the remote-controlled bus lurched towards the parking lot exit, the superstitious security youths fled. Paul was pulling anxiously on his collar as the PRS man began describing his collection of World War II Nazi ceremonial knives when a sudden crash split the tableau.
Jim had purchased me the gift of a complete black ninja stealth assassin outfit in Aracaju. I had been gearing up and crawling through the air conditioning ducts all this time. As I crashed through the cheap imitation-styrofoam hung ceiling tiles, skates first, I flashed ninja stars all about me. In the ensuing panic, Paul escaped to the pre-arranged bus pick-up point. Unfortunately, my ska era shoes were a poor choice of foot gear for escaping over the broken glass of the table I had landed on. Were it not for the confusion and the ninja-star-inflicted-wounds delivered to the bad guys, I would’ve been set upon while floundering on the glass-strewn carpet. As it happened, however, I leapt through the open door of the careening bus as it departed the city of Maringa forever.
If only we had managed to get our equipment in the bus, too…
Every word of this story is true.

The folks at Digital Kitchen have created a player piano that plays requests, and they call it Stanley. It works like this:
- Requests are sent via the @StanleyPiano Twitter account.
- A computer by the name of Stanford (apparently there is a lot of motherly love over there at DK) filters and queues up requests.
- When songs are ready to play, RT tweets are published back to the @StanleyPiano Twitter account.
- Songs are delivered via a custom MIDI interface to a custom-built key controller.
- Stanley rocks the house.
Stanley will be playing requests at the 2012 Capitol Hill Block Party. And they’ll be streaming the performance on the website.
Now that’s innovation. I applaud you, Digital Kitchen.

So everyone’s eyes are on touch-screen and mobile devices. Then along comes LEAP Motion which may create a fork in the road. It’s a remarkable technology that’s been hinted at for decades in science-fiction arena: human computer interaction using mid-air gestures.
Proprietors David Holz and Michael Buckwald say they’re going to change the world with this. And they’re probably right. I simply can not wait to get my hands on one of these. Or, not on one of these, which is precisely the point.

This is absolutely fascinating. I have pondered the technology behind digital photography but never acted on my impulses to research it. This video is 4 minutes of pure gold for anyone wanting to know how it works.
Thank you, Bill Hammack (a.k.a. “The Engineer Guy”), for sharing this insightful video about how charge coupled devices (CCD) work.

Ninja Blocks: Environment-Aware Computers
While I’m not completely following the pitch, I do understand the concept. Ninja Blocks are mini computers with sensors which make them environment aware. They sense light, motion, and temperature. And they can be programmed so that upon sensing something they take action.
They can perform familiar tasks such as turning on lights and more advanced tasks such as emailing you when a package arrives at your door or posting tweets on your behalf via pre-defined triggers.
There are two things I love about Ninja Blocks that differentiate them from other comparable products:
- Its basic tasks are plug-and-play for the layperson.
- Its hardware is open source, enabling the adventurous to build custom sensors and internal components.
The proprietors began their journey on Kickstarter like a lot of startups these days. And they received $103,000 while asking for $24,000. The public is certainly ready for these little ninjas. Congratulations, Maddy, Marcus, and Mark!
