Pen Draws Working Circuits With Silver Ink

Professors Jennifer Lewis and Jennifer Bernhard at the University of Illinois have come up with a way to draw circuits with a pen.

Not circuit diagrams. Any old pen can do that. No, the pen is a rollerball with silver ink that can actually draw real, working circuits. The ink dries to leave silver trails behind on the paper, and these are tough enough to survive bends and folds and still conduct electricity. And it doesn’t need to be paper. You can write on anything that will hold the ink.

Thus you can sketch a circuit, hook up components with crocodile clips and do anything you could do with a breadboarded circuit or even a proper circuit board. You’re only limit is how small you can scribble.

Next up in the project is the loading of other conductive materials, but the tech has already been co-opted for use as art. A sketched copy has been made of a painting by artist Jung Hee Kim. The lines of the drawing — a house and trees — becomes the wiring to connect an LED on the house’s roof.

In a Rush to Get Hitched? Insert Coins in the Marriage Machine

AutoWed Wedding Machine by Concept Shed from Conceptshed on Vimeo.

By Alice Vincent, Wired UK

It’s always nice when bonkers design concepts become a reality. Like a parking meter vending machine that will “marry” you and your buddies for jokes.

Concept Shed’s AutoWed Wedding Machine offers just that. This meticulously built 2.5-meter-tall [8-foot] creation started out as a joke until an American museum commissioned the Cornwall-based creative team to make it a reality.

AutoWed inventor Sam Lanyon explains to Wired.co.uk: “About a year and a half ago we were playing around with an idea about the bastardisation of a traditional wedding by crossing it with a parking meter. We stuck it into the sketchbook and it just sat there as an idea.”

Marvin’s Marvellous Mechanical Museum in Detroit, in the U.S., liked that idea. Thus, over 300 bespoke parts, made from materials ranging from plywood towaterjet-cut aluminium detailing were gathered and the Cadillac-pink love machine was born.

As the video above shows, the AutoWed machine mimics the ceremony used to unite couples in matrimony to produce a beautifully printed, if totally unofficial, certificate for a dollar or U.K. pound. Following the insertion of your spare change, you can enter the details of you and your partner or best-friend-forever on a fancy steampunk-inspired keyboard and enjoy the robotic voice reading out your respective names. In true vending machine style, the AutoWed also pops out a pair of rings in plastic eggs to complete the faux ceremony.

Lanyon has been amazed by the impact the super-cute machine has had. “Within three days of linking it on the website we’ve had 34 pages of Google results about it. It’s quite crazy.”

Indeed, such is the interest in bringing more AutoWed machines to a bar near you, Concept Shed is simplifying it for more profitable fun for the venues which choose to install it: “We’re going to be designing a simplified version. This one looks great but the custom-built keyboard and other details means that it’s quite expensive. So we’re producing a cut-down version for other bars to appreciate the payback.”

We don’t envisage any serious happily-ever-afters romances as a result of the AutoWed machine, but Concept Shed are pleased with the fact it exists: “It’s just a fun vending machine. We come up with crazy ideas and it’s great to be able to have the opportunity to make them.”


PossessedHand Takes Control of Your Hand, Freaks You Out

It’s creepy and it’s kooky, mysterious and spooky, it’s all together ooky…

If technology by researchers at the University of Tokyo ever ends up as a commercial product, then you could have the terrifying experience of your hand being possessed, moving itself without any commands from your own brain. You would, for all intents and purposes, become Bruce Campbell’s Ashley ‘Ash’ J. Williams in The Evil Dead.

The experimental device is actually called the PossessedHand, and controls your digits by shooting small electric currents into your wrist via electrodes strapped to your forearm. The PossessedHand runs on an Arduino micro-controller, and can auto calibrate itself to make sure it is twitching the corrects fingers and muscles inside your hand.

The theory is that the PossessedHand could be used to teach people to play musical instruments by training their fingers to move correctly. I’m not sure that this simple, mindless repetition would actually work without involving the brain. After all, “muscle memory” doesn’t actually reside in the muscles.

It could have medical benefits, teaching patients to use their hands again after strokes or accidents, and it would make a great gag gift to freak people out at parties.

Just make sure that the controls don’t get into the wrong hands (pun intended). Otherwise you, like Ash, could end the being strangled by your own hand.

Ren Ng Shares His Photographic Vision: Shoot Now, Focus Later

After buying his first digital camera, Ren Ng tried to snap a shot of a family friend’s vivacious 5-year-old daughter. Like many young, active children, it was incredibly difficult to focus the image properly and capture her fleeting smile in just the right way.

And then it came to him — what if you could take a picture, and then adjust the focus later?

That’s the story behind Ng’s startup Lytro and its revolutionary plenoptic camera, which lets users adjust the focus of a photograph after the fact thanks to an array of micro-lenses over the camera’s sensor. The result is a remarkable “living picture” (an example of which is included below. You can click around to change the focus of the image).

“There’s something about light field photography that’s just magical,” Ng says. “It very much is photography as we’ve known it. It’s what we’ve always seen through cameras — we just had to fix it. We’ve had these kind of pictures floating on our retinas, for as long as we’ve been humans.”

The implications for light field technology are very broad; they’re not just limited to consumer photography and picture taking. There are medical and scientific applications, for instance with microscopy, which is currently being studied at Stanford. It could also be used in industrial settings. “Anywhere that you need to take a picture and you have a lens in front of a sensor, you can do new things,” Ng says. Of course, 31-year-old Ng loves how light field photographs can capture a bigger picture of an event than conventional cameras. Not in the size sense; in the informational sense.

Ng was doing theoretical research at Stanford University in light fields at the time he tried to photograph his friend’s daughter. After sitting in on a research meeting discussing the design of a light field camera (which was formerly composed of an array of about a hundred digital cameras attached to a supercomputer when the technology was first introduced in the 90s), he thought to himself, “That sounds really cool, but that’s not going to be very practical.”

So Ng was prompted to switch his emphasis to cameras, specifically how he could shrink light field technology down into a commercial-size package. He spent time studying optics and working with electrical and mechanical engineering professors to put the camera together, since as a computer science student, he didn’t have that training.

After getting his Ph.D. (and receiving honors like the ACM Doctoral Dissertation Award in the process), Ng set out to put his research to use by starting a company that would produce light field cameras that everyone could enjoy. Four years later, Ng’s solo endeavor has expanded to over 45 employees, and his “competitively priced” camera will be available to consumers later this year.

Ng explains that these light field photographs are the same as what we had in the past, but now they have a bit more life, and this opens up all new kinds of creative avenues. The picture can tell a story.

“I just love taking pictures,” says Ng.

Light field cameras provide higher performance at a lower cost than could ever be possible in the past. However, details like the exact megapixel count and storage size of photographs taken with Lytro’s camera (and its exact price) are still under wraps until the product officially launches.

A Lytro camera, hidden under the furry shell of a stuffed animal shark, snaps images of guests and circus performers at the company's launch party.

“The megapixel war in conventional cameras has been a total myth,” Ng says. “It’s taking us all in the wrong direction. Once a picture goes online, you’re throwing away 95 to 98 percent of those pixels. Light fields can use all that resolution, those megapixels, harness them, and drive them into the future.”

Light field technology simplifies the hardware of a camera, since the processing is all done with advanced software. But the resulting interactive images don’t require any dedicated software. Lytro integrates HTML5, Flash and other native app technologies to create a simple, unified experience that anyone can view or work with. The company does have a Facebook app coming out soon, though.

So will we be seeing Lytro’s light field technology anywhere else soon, say in smartphones?

“Smartphone technology is very important and is directly applicable to light field technology, but as a startup, our focus at this stage is just on our own camera for now,” Ng says.

Although partnerships with existing camera or smartphone manufacturers is potentially quite a ways off, at least we can look forward to Lytro’s camera later this year.


How to Make a Clock Run for 10,000 Years

Jeff Bezos

High on a rocky ridge in the desert, nestled among the brush, is the topmost part of a clock that has been ticking for thousands of years.

It looks out over the ruins of a spaceport, built by a rich man whose name was forgotten long ago.

Most of the clock is deep inside the mountain, below the ridgeline. To get there, you hike for days through the heat; the only sounds are the buzzing of flies and the whisper of the occasional breeze. You climb up through the brush, then pass through a hidden door into the darkness and silence of the clock chamber. Far above your head, in the darkness, a massive pendulum swings slowly back and forth, making the clock tick once every 10 seconds.

‘In the year 4000, you’ll go see this clock and you’ll wonder, “Why on Earth did they build this?”‘ — Amazon CEO Jeff Bezos

No one knows who built it, or why. They built it well, and even now it keeps perfect time. All we know of these strange people is that they were obsessed with the future.

Why else would they build something that had no purpose except to mark time for thousands of years?

The rich man is Amazon.com founder Jeff Bezos, and he has indeed started construction on a clock that he hopes will run for 10,000 years.

For Bezos, the founder of Amazon.com, the clock is not just the ultimate prestige timepiece. It’s a symbol of the power of long-term thinking. His hope is that building it will change the way humanity thinks about time, encouraging our distant descendants to take a longer view than we have.

For starters, Bezos himself is taking a far, far longer view than most Fortune 500 CEOs.

“Over the lifetime of this clock, the United States won’t exist,” Bezos tells me. “Whole civilizations will rise and fall. New systems of government will be invented. You can’t imagine the world — no one can — that we’re trying to get this clock to pass through.”

To help achieve his mission of fostering long-term thinking, Bezos last week launched a website to publicize his clock. People who want to visit the clock once it’s ready can put their names on a waiting list on the site — although they’ll have to be prepared to wait, as the clock won’t be complete for years.

It’s a monumental undertaking that Bezos and the crew of people designing and building the clock repeatedly compare to the Egyptian pyramids. And as with the pharaohs, it takes a certain amount of ego — even hubris — to consider building such a monument. But it’s also an unparalleled engineering problem, challenging its makers to think about how to keep a machine intact, operational and accurate over a time span longer than most human-made objects have even existed.

Consider this: 10,000 years ago, our ancestors had barely begun making the transition from hunting and gathering to simple agriculture, and had just figured out how to cultivate gourds to use as bottles. What if those people had built a machine, set it in motion, and it was still running today? Would we understand how to use it? What would it tell us about them?

And would it change the way we think about our own future?

The idea for the clock has been around since Danny Hillis first proposed it in WIRED magazine in 1995. Since then, Hillis and others have built prototypes and created a nonprofit, the Long Now Foundation, to work on the clock and promote long-term thinking. But nobody actually started building a full-scale 10,000-year clock until Bezos put up a small portion — $42 million, he says — of his fortune.

Last year, contractors started machining components, such as a trio of 8-foot stainless steel gears and the Geneva wheels that will ring the chimes. Meanwhile, computers at Jet Propulsion Laboratories have spent months calculating the sun’s position in the sky at noon every day for the next 10,000 years, data that the clock will use to correct itself. This year, excavation began on the Texas desert site where the clock will be installed deep underground.

And just last month, the Smithsonian agreed to let the Long Now Foundation install a 10,000-year clock in one of its Washington museums, once they can find someone to fund it.

It seems that the time for millennium clocks has arrived.

The Project

Making a clock that will run for 10 millennia is no small undertaking. In Texas, the builders have started drilling a horizontal access tunnel into the base of the ridge where the clock will live. They’ll drill a pilot hole, 500 feet straight down from the top of the ridge, until it meets the access tunnel. Then they’ll bring a 12-foot-7-inch bit into the bottom and drill it back up, carving out a tall vertical shaft as it goes.

Afterwards, they’ll install a movable platform holding a 2.5-ton robot arm with a stonecutting saw mounted on the end. It will start carving a spiral staircase into the vertical shaft, from the top down, one step at a time.

The clock, with massive metal gears, a huge stone weight, and a precise, titanium escapement inside a protective quartz box, will go deep into the shaft. A few years from now, the makers will set it in motion.

Some day, thousands of years in the future, when Bezos and Amazon and even the United States are nothing more than memories, or less even than that, people may discover this clock, still ticking, and scratch their heads.

Bezos says, “In the year 4000, you’ll go see this clock and you’ll wonder, ‘Why on Earth did they build this?’”

The answer, he hopes, will lead you to think more profoundly about the distant future and your effects on it.

Here are some of the people who are creating the most temporally ambitious mechanical engineering project in human history.


5 Robots That Can Get Their Groove On

In case you haven’t heard, Rebecca Black pulled her “Friday” video from YouTube this week. Now what are we going to be “so excited” about?

Over here at Gadget Lab, we’re so excited about robots.

We’ve seen robots that can crawl and walk, ones that can climb walls using electroadhesive film, and some that are a bit less talented, but just look darn good.

Today, we focus on bots that have one thing in common: These guys can dance.

Check out everything from the HRP-4C’s uncanny valley-straddling popstar-style moves (above), to the cute, cheerful bouncing of the squishy yellow Keepon.

I wonder how long we’re going to have to wait for a Saturday Night Fever cast entirely with robots. I give it two years.

Above:

Pop Sensation HRP-4C

HRP-4C is half fembot, half stormtrooper, and all talent.

Over 30 motors in HRP-4C’s humanoid form allow her 5-foot, 2-inch frame to move like a human. She was developed by the National Institute of Advanced Industrial Science and Technology in Japan.

The video above is from the 2010 Digital Content Expo, which took place in October. Her voice is that of Kaori Mochida, a Japanese pop star, after being run through AIST’s synthesizer software called VocalListener.

Her most recent escapade, below, is performing at Yamaha Motors’ booth at the 2011 Jisso Protec show. Maybe we’ll get to see her stateside at CES 2012. I can only hope.

Pulseless Artificial Heart Never Misses a Beat

This artificial heart pumps blood continuously using propeller screws. Photo Texas Heart Institute

55 year old Craig Lewis lived for a month without a heartbeat or a pulse. If you had listened to his chest, you would heard silence. If you had hooked him up to an electrocardiograph, you wouldn’t have heard the familiar beep, beep, beep. You would have seen a flat line.

Lewis heart was replaced with a pair of pulseless pumps. Cobbled together from existing ventricular-assist implants and “a moderate amount of homemade stuff,” by Dr. Billy Cohn and Dr. Bud Frazier of the Texas Heart Institute, the artificial heart continuously pumps blood using screw-shaped propellers. Hence, constant blood flow without a beat.

Cohn says that the beat is there only because that’s the way the heart works. When they swapped it out for their contraption, “none of the other organs seem[ed] to care much,” he told NPR.

Unfortunately Lewis died a month later due to his disease, but there is another artificial, pulseless heart in action. Abigail is a calf with one of Cohn and Frazier’s hearts, and she is doing fine.

Cohn sees this heart as the future. He likens artificial pulsing hearts to flying machines with flapping wings — mimicking nature is not always the best solution for a machine.

With its single moving part, Cohn and Frazier’s device certainly seems to make a lot of sense. The only problem might be social. After all, without a pulse or a heartbeat, how do you tell if somebody is alive or dead?

Tiny Rotary Engines Could Power Gadgets with Gasoline

This artist’s rendering shows how Clarian’s hybrid battery could be put together

Clarian Lab’s new generator is a gas-powered battery. That might sound backward in today’s world of hybrid cars, but it actually turns out to be a pretty clever device.

The Hybrid Battery is small, ultra-simple rotary engine with just two moving parts. Rotary engines — like the famous Wankel — are highly efficient and do away with pumping pistons an instead use a spinning rotary piston.

Clarian’s model runs on gasoline, kerosene, propane, natural gas, ethanol, methanol or hydrogen. In short, pretty much any hydrocarbon-based biofuel you can get your hands on. Since fuels like gas have much higher energy densities than electrical batteries (20-30 times better, according to Clarian), it makes for longer operation and — if you use fuels cells — instant recharging.

The trick that makes Clarian’s engine different is that it uses electricity to spin the piston inside the engine and draw in, compress and then ignite the fuel. The subsequent explosion then occurs as normal and the movement is converted to electricity and siphoned-off. The big difference is in using electricity to control the speed of the piston, and therefore control the timing and efficiency. And because the piston itself spins, there’s no need for a separate drive shaft to power a generator. This keeps things very small.

It’s unlikely you’re ever going to put one of these into your laptop, and you’d poison yourself with carbon monoxide if you ever did it indoors anyway. But this could be an efficient and powerful way to replace generators, and even to power cars. Clarian’s prototype outputs 5kW of power from its 125cc engine, and weighs around 10kg including the fuel. In the future it actually could be small enough to fit inside handheld gadgets.

Camera Reads Fingerprints From a Distance in Seconds

Your Jedi mind tricks will not work on me

In the future (or distant past?), Obi Wan Kenobi might not be quite so cocky about which droids you are looking for. If the Empire had equipped its weak-minded Storm Troopers with the AIRprint Fingerprint scanner, it would have seen his arrogant hand wave and recorded the prints of each of his self-important fingers.

The AIRprint may sound like something from Apple (actually, it sounds exactly like something from Apple), but is in fact a box that can read fingerprints from over six feet away. It uses two 1.3MP cameras which are each tuned to a different plane of polarized light, one horizontal and one vertical. The box sends out a beam of polarized light and while one camera sees peaks, the other sees valleys, effectively upping the resolution greatly. This allows it to photograph your prints from afar in around one second per finger.

The main use would be building security, speeding up scans and making them easier to do. Future versions of this experimental tech will be faster and able to scan a whole hand’s worth of fingers at once. When that happens, George Lucas may have to rewrite the famous scene.

Obi Wan: “These are not the droids you’re looking for. Move along.”

TSA Storm Trooper: “These are not the… Wait. Sir, please follow me.”

Obi Wan (waving hand): “You will not perform a body cavity search on me.”

TSA Storm Trooper: “Sir, please stop that. You’re embarrassing yourself.”
