Chris Selley on the disproportional sentences handed out by the “court of public opinion”

Filed under: Law, Media, Technology — Tags: , , , , — Nicholas @ 09:59

People can be idiots. Some of them are idiots all the time. Others are only idiots every now and again. When the idiotic events happen to co-incide with fluctuating public opinion, the sentence for public idiocy can often vastly exceed the impact of the original idiotic action:

It has been a tough week for notorious, misbehaving young people — well, outside of Quebec anyway. On Monday in a New Jersey courtroom, Dharun Ravi was sentenced to 30 days in jail for having briefly spied, twice, via webcam, on his Rutgers University roommate’s romantic encounters. He was 18 at the time. And on Tuesday, Swansea University, in South Wales, made it clear that 21-year-old Liam Stacey is forever unwelcome on its campus, where he was nearly done studying biology. Mr. Stacey just served half of a 56-day jail sentence for publishing some flamboyantly racist tweets. “Go suck a ni–er d-ck you f–king aids ridden c–t,” one read.

Both individuals are unredeemed pariahs. Yet on either side of the Atlantic, and across the political spectrum, their cases have sparked an interesting debate over whether criminal justice was the proper means through which to express polite society’s revulsion at their actions. I think it was not, for the simple reason that the charges bore little relationship to the true nature of the outrage.

[. . .]

The context of Mr. Stacey’s crimes is less tragic. On March 17, before a television audience of millions, Premier League soccer player Fabrice Muamba collapsed of a heart attack. (He has since made a remarkable recovery.) In response, an admittedly soused Mr. Stacey Tweeted the following: “LOL. F–k Muamba he’s dead!!! #Haha.” That astoundingly insensitive missive was what elicited society’s outrage; it is still quoted at least 100 times in the media for every mention of the torrent of racist abuse that followed, when fellow tweeters complained.

Twitter is not, generally speaking, a racism-free zone; earlier in this year’s NHL playoffs, it hosted some jaw-dropping invective against Washington Capitals forward Joel Ward. And British white trash can match or exceed anything their North American counterparts are capable of. So here it is even clearer: Mr. Stacey’s problem wasn’t “inciting racial hatred,” the charge of which he was convicted, but doing it at the wrong time and getting noticed.

In the end, while two months was a remarkably harsh sentence for mere words, it’s hard to feel sorry for Mr. Stacey. One can argue for unfettered free speech, and equal application of the law, without defending this particular oik.

SpaceX Dragon launches successfully

Filed under: Space, Technology, USA — Tags: , , , , — Nicholas @ 09:10

Brid-Aine Parnell reports on today’s launch of the SpaceX Dragon:

History is just days away from being made as SpaceX’ Dragon cargoship finally blasted off successfully on its Falcon 9 rocket this morning on its way to a rendezvous with the International Space Station.

Elon Musk’s private space firm has had a number of setbacks with the latest test flight of the Dragon, delaying again and again to make sure the software that will put it within spitting distance of the ISS was working properly. And just when it seemed there was no stopping the takeoff last Saturday, the computer held the ship on the ground.

The engines were already firing when the computer “saw a parameter it didn’t like” and aborted the trip. SpaceX engineers later replaced a faulty pressure valve.

However this morning at 08:44 UK time (03:44 US Eastern) there were no problems and the Falcon 9 rocket lifted off on schedule to place the Dragon capsule into an orbit which will carry it to a rendezvous with the station on Friday if all goes to plan.

The first hurdle in the commercial company’s maiden berthing with the ISS has been jumped, with the Dragon out of Earth’s atmosphere, but there’s still a lot to prove before Houston will give the go to attempt a docking.

SpaceX Dragon launch aborted, rescheduled to Tuesday at the earliest

Filed under: Space, Technology, USA — Tags: , , , , — Nicholas @ 09:13

Lewis Page at The Register on the scrubbed launch this morning:

The Falcon 9 rocket from private space company SpaceX, intended to launch this morning and send a Dragon capsule loaded with supplies to the International Space Station, has failed to take off. The rocket’s computer aborted the launch automatically at almost the final possible moment, when its engines had already ignited but the vehicle had not yet been released from the pad.

“The computer saw a parameter it didn’t like,” commented launch controllers after the abort, which saw the Falcon’s 9 main engines flare briefly into life as the countdown reached zero before cutting out again.

The rocket is not thought to have been damaged by the aborted launch, and controllers announced a provisional plan to check the craft, refuel it and make another launch attempt on Tuesday morning at 03:44 AM local time (08:44 UK time).

SpaceX Dragon smuggling secret cargo to ISS

Filed under: Space, Technology, USA — Tags: , , , , — Nicholas @ 08:35

At The Register, Brid-Aine Parnell gets all conspiracy theorized:

Just to add some icing to the SpaceX Dragon launch cake, the cargoship may be carrying a secret payload that nobody knows about.

The first ever commercial spacecraft to dock with the International Space Station, due to go up tomorrow, will already be carrying nonessential food, student science projects, clothes and other supplies for the ISS crew, but Elon Musk’s firm has also hinted there could be something else aboard.

On the last test flight of the Dragon, the craft carried a Top Secret cargo SpaceX refused to reveal to anyone until after mission, which turned out to be a lovely big wheel of cheese in an homage to the classic Monty Python sketch in the cheese shop.

On a slightly more serious level, Jonathan Amos has this report at the BBC News site:

Although billed as a demonstration, the mission has major significance because it marks a big change in the way the US wants to conduct its space operations.

Both SpaceX and another private firm, Orbital Sciences Corp, have been given billion-dollar contracts to keep the space station stocked with food and equipment. Orbital hopes to make its first visit to the manned outpost with its Antares/Cygnus system in the coming year.

Lift-off for the Falcon is timed for 04:55 EDT (08:55 GMT; 09:55 BST). It is going up from Cape Canaveral Air Force Station.

The ascent phase should last a little under 10 minutes, with the Dragon capsule being ejected just over 300km (185 miles) above the Earth.

The conical spaceship will then deploy its solar panels and check out its guidance and navigation systems before firing its thrusters to chase down the station.

A practice rendezvous is planned for Monday when Dragon will move to within 2.5km (1.5 miles) of the station.

If Nasa and SpaceX are satisfied that the vehicle is performing well, it will be commanded to fly up and over the outpost in preparation for close-in manoeuvres on Tuesday.

The sickly Raptor spawns another concern

Filed under: Military, Technology, USA — Tags: , , — Nicholas @ 07:59

As if the F-22 hadn’t already had enough issues, there’s a new concern called the “Raptor cough” (acceleration atelectasis) showing up among F-22 pilots:

Increasingly desperate to find out what is causing its F-22 (“Raptor”) fighter pilots to get disoriented while in the air, the U.S. Air Force is now investigating what appears to be excessive coughing by F-22 pilots. It’s being called “Raptor Cough” and is actually a known condition (acceleration atelectasis) for pilots who have just completed a high speed maneuver. But it appears to be showing up more frequently among F-22 pilots. That may be the result of months of tension over the reliability and safety of the aircraft. The F-22 pilots are perplexed and a bit nervous about their expensive and highly capable jets.

The air force believes that something, as yet unknown, is getting into the pilot air supply and causing problems. Despite this, the air force continues flying its F-22s. The decision to keep flying was made because the air supply problems have not killed anyone yet and they are rare (once every 10,000 sorties).

The 14 incidents so far were all cases of F-22 pilots apparently experiencing problems. The term “apparently” is appropriate because the pilots did not black out and a thorough check of the air supply system and the aircraft found nothing wrong. There have been nearly 30 of these “dizziness or disorientation” incidents in the last four years, with only 14 of them serious enough to be called real incidents. Only one F-22 has been lost to an accident so far and, while that did involve an air supply issue, it was caused by pilot error, not equipment failure.

Disruptive technologies and naval warfare

Filed under: Military, Technology — Tags: , , — Nicholas @ 09:28

Naval warfare has seen several revolutions as new technology disrupts the status quo. The pace of innovation has meant shorter spans of time between revolutionary developments, and this is a serious problem for naval powers as ships take so long to build and have to serve for lengthy periods of time.

Last year, I posted an article about how the Royal Navy had attempted to ride the technological changes during the Victorian era, with varying levels of success:

Fifty years later, the stasis is being broken technologically. Wind power is giving way to steam. Solid shell cannon are starting to give way to both larger and more complex weapons. Iron is starting to supplant oak as the material of choice for shipbuilding. The renowned duel between USS Monitor and CSS Virginia (formerly the USS Merrimac) sets all the major navies of the world busy considering how to protect their existing fleets and merchant vessels against the new threat of the ironclad.

The English government is suddenly faced with the stark reality that their entire fleet has become or is about to become obsolete. Neither Monitor nor Virginia are ocean-going ships, but the message is clear that no wooden vessel has a prayer of survival against the modern steam-powered ironclad. And even the greatest economic power in the world can’t replace an entire fleet overnight.

The Admiralty couldn’t depend on past experience for guidance, as everything they’d done for hundreds of years was now undecided: what kind of ships do you need to build? How will they be armed? How will they be armoured? How will they be propelled? Bureaucracies are, by nature, not well equipped to face challenges like this. The Royal Navy, from the late 1860′s until the late 1880′s struggled with finding the correct answer, or combination of answers, to meet the needs of the day.

It’s not just a single change — like the switch from sail to steam power — it’s multiple changes, each with their own array of materials, training, support, and maintenance changes that force organizations to adapt. This runs directly into the problem that it takes years to design, build, arm, equip, and crew a new ship. The pace of change was so brisk in that period that ships could literally be obsolete before they were commissioned into the fleet. And bureaucracies are by their very nature, ill-suited to cope with disruptive change: they thrive on routine and predictability.

Today, the US Navy finds itself in the same relative situation as the Royal Navy of Queen Victoria: the most powerful fleet in the world, but facing uncertainty due to technological changes. Strategy Page has a brief run-down of the potentially disruptive developments we may see in the near future:

The 21st century is barely underway, and much unknown technology is yet to be invented. Many of the key warship technologies were unknown in 1912. But we can already see some new stuff which is leading revolutionary changes in how navies will operate this century. Here some of the more obvious ones.

Unmanned vehicles. Unlike aircraft, which were a new vehicle, UAVs (Unmanned Aerial Vehicles), UUVs (Unmanned Underwater Vehicles) and USVs (Unmanned Surface Vehicles) are radically new technologies. There are already examples of all three in service. There will be more and they will change everything by incorporating more powerful AI and new weapons. That said, UUVs were first developed in the 19th century (the modern torpedo) and 20th (guided missiles). But these two weapons were not flexible enough to change as many aspects of naval warfare as unmanned vehicles will be doing.

Super Sensors. Sonar (using sound to detect objects underwater) appeared during World War I (1914-18) while radar (using radio signals to detect objects in the air) was developed during the 1930s and widely used during World War II (1939-45). Widely recognized as the first electronic sensors (although the earliest sonars were all-acoustic), their 21st century descendants are much more capable. More powerful computers and transmitting technology has since produced several generations of cheaper, more reliable and more powerful sensors. This is continuing and the power of new sensors will make it much more difficult to hide. Stealth is still important for spoiling the aim of long range guided weapons. But the super sensors make it much more difficult to achieve surprise by coming out of nowhere.

Other items on this list include artificial intelligence (AI), all-electric ships, stealth technology, networking, composite materials, space-based services, nanotech, and laser weapons. Lots of ways for admirals to lose sleep over the next few years.

Nerd politics: problems and opportunities

Filed under: Government, Liberty, Politics, Technology — Tags: , , , , , , — Nicholas @ 00:08

Cory Doctorow in the Guardian on the current state of “nerd politics:

In the aftermath of the Sopa fight, as top Eurocrats are declaring the imminent demise of Acta, as the Trans-Pacific Partnership begins to founder, as the German Pirate party takes seats in a third German regional election, it’s worth taking stock of “nerd politics” and see where we’ve been and where we’re headed.

Since the earliest days of the information wars, people who care about freedom and technology have struggled with two ideological traps: nerd determinism and nerd fatalism. Both are dangerously attractive to people who love technology.

In “nerd determinism,” technologists dismiss dangerous and stupid political, legal and regulatory proposals on the grounds that they are technologically infeasible. Geeks who care about privacy dismiss broad wiretapping laws, easy lawful interception standards, and other networked surveillance on the grounds that they themselves can evade this surveillance. For example, US and EU police agencies demand that network carriers include backdoors for criminal investigations, and geeks snort derisively and say that none of that will work on smart people who use good cryptography in their email and web sessions.

But, while it’s true that geeks can get around this sort of thing — and other bad network policies, such as network-level censorship, or vendor locks on our tablets, phones, consoles, and computers — this isn’t enough to protect us, let alone the world. It doesn’t matter how good your email provider is, or how secure your messages are, if 95% of the people you correspond with use a free webmail service with a lawful interception backdoor, and if none of those people can figure out how to use crypto, then nearly all your email will be within reach of spooks and control-freaks and cops on fishing expeditions.

[. . .]

If people who understand technology don’t claim positions that defend the positive uses of technology, if we don’t operate within the realm of traditional power and politics, if we don’t speak out for the rights of our technically unsophisticated friends and neighbours, then we will also be lost. Technology lets us organise and work together in new ways, and to build new kinds of institutions and groups, but these will always be in the wider world, not above it.

Dragon flight now scheduled for May 19

Filed under: Space, Technology — Tags: , , , — Nicholas @ 09:24

Brid-Aine Parnell at The Reg updates us on the SpaceX flight schedule:

The flight of the Falcon 9 has once more been rescheduled, with a new launch date of 19 May, as Elon Musk’s SpaceX decided to tweak the software one more time.

The first commercial craft to restock the International Space Station, a Dragon capsule strapped to a Falcon 9 rocket, has seen more than its fair share of push-backs for the test flight, but it will all pay off if the cargo ship can dock with the station.

SpaceX has already shown it can release and retrieve the Dragon, but getting it to motor alongside the fast-moving ISS and accurately berth with it is no mean feat and the firm has tested and retested the necessary software in the hopes it won’t end up with egg on its face.

[. . .]

Providing this test flight is successful, the Dragon will start to fulfil the contract for a minimum of 12 flights to resupply the ISS. Since the ship is reusable, it will be the only spacecraft capable of bringing cargo back with it as well. And, ultimately, SpaceX hopes that a version of the Dragon will be its first manned spaceship as well.

The military trade-off between protection and mobility

Filed under: Military, Technology, USA — Tags: , , — Nicholas @ 10:55

Strategy Page on what’s weighing down American infantrymen now:

There is a rebellion brewing in the U.S. Army and Marine Corps. It’s all about the protective vest. This lifesaving bit of equipment has saved thousands of lives in the last two decades, but has, because of political grandstanding and media distortions, become too heavy and restrictive. The troops want lighter body armor, even if it does increase vulnerability to bullets. Marine and army experts point out that the drive (created mainly by politicians and the media) for “better” body armor resulted in heavier and more restrictive (to battlefield mobility) models. This has more than doubled the minimum weight you could carry into combat.

Until the 1980s, you could strip down (for actual fighting) to your helmet, weapon (assault rifle and knife), ammo (hanging from webbing on your chest, along with grenades), canteen and first aid kit on your belt, and your combat uniform. Total load was 13-14 kg (about 30 pounds). You could move freely and quickly like this, and you quickly found that speed and agility was a lifesaver in combat. But now the minimum load carried is twice as much (27 kg) and, worse yet, more restrictive.

While troops complained about the new protective vests, they valued it in combat. The current generation of vests will stop rifle bullets, a first in the history of warfare. And this was after nearly a century of trying to develop protective vests that were worth the hassle of wearing. It wasn’t until the 1980s that it was possible to make truly bullet proof vests using metallic inserts. But the inserts were heavy and so were the vests (about 11.3 kg/25 pounds). Great for SWAT teams, but not much use for the infantry. But in the 1990s, additional research produced lighter bullet proof ceramic materials. By 1999, the U.S. Army began distributing a 7.3 kg (16 pound) “Interceptor” vest that provided fragment and bullet protection. This, plus the 1.5 kg (3.3 pound) Kevlar helmet (available since the 1980s), gave the infantry the best combination of protection and mobility. And just in time.

US Postal Service develops a lithium allergy

Filed under: Military, Technology, USA — Tags: , , , — Nicholas @ 08:34

The United States Postal Service has announced that they will no longer allow shipments that include lithium batteries, as of May 16th:

If you want to send an iPad, a Kindle Fire, an iPhone, a laptop, or a similar device overseas, now is the time to send it, because as of next week, the U.S. Postal Service will be banning all electronic gadgets that contain a lithium battery.

The reason? Those lithium batteries can potentially explode or catch fire when devices are shipped with a full charge, improperly stored, or improperly packed. Lithium battery related fire incidents have occurred 17 times on passenger flights since 2004, and have been implicated in at least one major crash of a UPS plane.

As a result of the ban, people who want to ship electronic devices to troops or to family overseas will have to use a private delivery service, such as UPS, DHL, and FedEx, which are pricy alternatives.

[. . .]

USPS’s refusal to ship devices with lithium batteries will have the greatest impact on military serving overseas (DHL and UPS do not deliver to APO or FPO boxes) and commercial resellers, who will have to increase shipping costs and rely on FedEx, DHL, and UPS, which still have challenges in countries like Russia.

Britain’s government websites under attack

Filed under: Britain, China, Government, Technology — Tags: , , , — Nicholas @ 09:06

Perhaps I’m just cynical, but I had expected that any government website would need to be “hardened” against attack. The British government’s many official websites have indeed been undergoing attacks for quite some time:

The British Ministry of Defense has admitted, for the first time, that it is under heavy attack by hackers. It was also revealed that some of these attacks had succeeded. The good news is that the military is becoming more aggressive and imaginative in dealing with Cyber War defense. China was not directly accused of being behind any of these attacks, but it was mentioned that there are now discussions underway with the Chinese on the matter. All this is an old problem.

Last year, Britain went public to report a higher number of Internet based attacks. The report noted that the emphasis was now on economic assets. This included technology and business plans. For example, the Foreign and Commonwealth Office was under heavy cyber-attack for several months, apparently in an effort to obtain secret details of government plans and techniques for supporting British exports. Government Internet security officials were making all this public to encourage British firms to increase their Internet security.

All this was nothing new. Two years ago Britain’s domestic intelligence service, MI5, went public with numerous charges of Chinese Internet based espionage. MI5 accused China of using both agents and hacker software, to obtain secrets from specific companies and government organizations. This approach had Chinese personnel approaching specific British businessmen at trade shows, and offering gifts, like a thumb drive loaded with hidden hacker software that will load itself on to the victim’s PC and seek out valuable information. Internet based attacks, traced back to China, continue to send real looking email that has an attachment containing another of those stealthy hacker programs that seek out secrets, or even quietly take over the user’s PC. Three years ago, MI-5 sent alerts to major corporations warning them of similar attacks and advising increased security of their data.

Royal Flying Corps, 100 years on

Filed under: Britain, History, Military, Technology, WW1 — Tags: , , — Nicholas @ 10:25

April 13th was the 100th anniversary of the founding of the Royal Flying Corps (RFC), which was merged with the Royal Naval Air Service (RNAS) to become the Royal Air Force in 1918. BBC Magazine has an interesting article about the early days:

In most accounts of WWI, mention of the Royal Flying Corps goes hand-in-hand with stories of the fighter aces, men like Albert Ball and James McCudden, who downed dozens of enemy planes.

The romance of gladiatorial combat in the air — initially firing revolvers at one another from the cockpit, and then shooting machine guns through the propellers of the aircraft — makes their adventures against such legendary foes as the Red Baron some of the most stirring tales of the Great War.

But as a division of the British Army, the main role of the Royal Flying Corps, with its hundreds of pilots and thousands of ground crew, was very different.

It was the eyes of the army.

For the first time in history, it was possible not only to get a detailed view of the enemy lines from above, but to see what was going on behind those lines — the trench systems, the support routes, the railways and road vehicles that manoeuvred troops and weaponry into position.

The real heroes of the war in the air were the pilots and observers who flew in all conditions to maintain British air superiority, and to keep the ground troops aware of everything that the enemy was doing.

During the First World War, Canada hosted a training unit for British aircrew, the Royal Flying Corps Canada (Wikipedia link), from 1917 onwards. It operated the following air stations in southern Ontario:

  • Camp Borden 1917–1918
  • Armour Heights Field 1917–1918 (pilot training, School of Special Flying to train instructors)
  • Leaside Aerodrome 1917–1918 (Artillery Cooperation School)
  • Long Branch Aerodrome 1917–1918
  • Curtiss School of Aviation (flying-boat station with temporary wooden hangar on the beach at Hanlan’s Point on Toronto Island 1915–1918; main school, airstrip and metal hangar facilities at Long Branch)
  • Deseronto Airfield, Deseronto 1917–1918 (pilot training)
  • Camp Mohawk (now Tyendinaga Mohawk Airport) and Camp Rathburn — located at the Tyendinaga Indian Reserve near Belleville 1917–1918 (pilot training)
  • Hamilton (Armament School) 1917–1918
  • Beamsville Camp (Aerial fighting)

List sourced from the Wikipedia page on the RFC.

[Lt Col (later Brig Gen) Cuthbert] Hoare made several agreements with U.S. Brig Gen George O. Squier (US Army Signal Corps) and the US Aircraft Production Board. Squier had overall responsibility for the US Army’s air service, which was short of flight instructors. The RFC released five experienced American pilots to the US Army, where they became squadron commanders. The US Air Board acquiesced in the British opening a recruiting office in New York City, ostensibly to recruit British citizens, but in fact also soliciting US citizens, of whom about 300 were successfully signed up. The RFC would also train many US Army flight personnel: 400 pilots; 2,000 ground-crew members; and 20 equipment officers. These Americans would then collect aircraft and equipment from the UK, before coming under RFC control in France. Ten American squadrons would train in Canada during the summer of 1917, while RFC squadrons were allowed to train during the winter in Fort Worth, Texas.

During the last two years of the war 3135 pilots and 137 observers trained in Canada and Texas for both the RFC and the new Royal Air Force (RAF). Of these trainees, 2,624 went to Europe for operational duty.

Technology is not the panacea

Filed under: Education, Health, India, Technology — Tags: , , , , — Nicholas @ 10:06

I’m generally very pro-technology, but the One Laptop Per Child (OLPC) effort always struck me as putting the technology cart in front of the educational (and cultural) horse. A report at The Economist has examples of technological fixes that haven’t actually “fixed” the problems they were intended to solve:

The American charity has an ambitious mission — transform the quality of education in the developing world by giving every poor student a laptop. Targeting a $100 laptop, OLPC succeeded in creating a usable computer at a very low price point (the actual number was closer to $200). Unfortunately most of the attention in the project was focused on the technology and not enough on its efficacy. In the first rigorous evaluation of the programme, the Inter-American Development Bank (IDB) found little evidence that the laptops influenced educational outcomes. The study, conducted in Peru four years after the programme was launched, found no improvement in math or language. While the computers did lead to some gains in cognitive skills, the authors concluded that access to a laptop didn’t improve attendance. Neither did it motivate students to spend more time on their homework.

There is similarly disappointing news on cooking stoves. The World Health Organization estimates that indoor pollution from primitive cooking fires contributes to 2m deaths annually. One solution is to use clean cooking stoves. At a cost of $12.50, these stoves are an inexpensive way to reduce respiratory ailments and improve air quality. The Global Alliance for Clean Cookstoves (GACC), a public-private initiative, is making a big push for 100m homes in the developing world to switch to clean stoves by 2020. But a new NBER paper by Rema Hanna from Harvard University and Esther Duflo and Michael Greenstone from MIT, questions the long-term health or environmental benefits from this programme. The authors evaluated a clean-stove programme in eastern India, covering 15,000 households over five years. Their study found that after the initial year, enthusiasm for the stoves waned and households didn’t make the necessary investments to maintain them. As a result, the programme had very little effect on respiratory health or air pollution.

Both these projects highlight some common misconceptions in using technology for development. For one, solving intractable social problems requires fundamental changes in the target population. It also needs a supportive institutional framework to reinforce the right behaviour. Technology can complement this process, but it is no substitute for the human element. In Peru, simply adding laptops to the classroom, without investing in teachers who were proficient in computer-aided education, meant that the academic impact was limited. The IDB paper rightly points out that in poor countries where wages are low, development money may be better spent on labor-intensive education interventions than on expensive tools.

Printed electronics: from gimmick to gizmo

Filed under: Technology — Tags: — Nicholas @ 07:45

Bill Ray looks at some companies working in the printed electronics field:

“Printed electronics” is one of those terms one sees being bandied about without really knowing what it means or why it’s important. The premise of using printing techniques to create electrical circuits isn’t hard to comprehend, but not everyone agrees on what comprises a “printing technique” or why you might want to use one, so El Reg chatted to three companies at the forefront of the field.

According to these firms, the new printing technique is going to change the literal fabric upon which the electronics industry rests. That’s important as it’s not the electronics which change as a result of the printing process, but rather the material on which those electronics rest. So instead of being etched on silicon the circuits can be laid onto steel, plastic, or even paper, and it’s that change of substrate which links all the various techniques and makes printed electronics so exciting.

[. . .]

This is in contrast to Silicon Valley’s Kovio, which steps away from standard printing equipment but still uses ink-jet techniques to lay down working RFID chips onto a flexible steel substrate.

The mechanism is the same as a desktop ink-jet, only instead of ink the jets squirt out ca conductor into wires as little as eight microns thick, making up chips which will run up to 40MHz or so. But Kovio can print a lot of them very cheaply and hopes to get the Near Field Communications (NFC) standard extended to include its vision of printed RF barcodes, powered by induction from the reading device and able to respond with a standardised serial number.

[. . .]

Such a step is taken by PragmatIC, another Cambridge-based company and one we’ve mentioned before thanks to their light-up beer bottles and induction-powered screens. PragmatIC doesn’t so much print electronics as imprint them, creating a sandwich of materials and then, using a pre-cut die, press down and carve out the shape required.

That might be taking the concept a long way from printing, though PragmatIC reckons it takes printing back to its roots. Imprinting is also the process used to stamp out CDs and Blu-Ray disks, and so is known to work within very strict tolerances. PragmatIC reckons it can get down to 100nm objects placed with 10nm accuracy, leading to transistors around a square-micron in size which (PragmatIC claims) is comparable to silicon technologies.

That means chips can be made cheaper, but more importantly they can be laid onto any surface (there’s no baking in the PragmatIC process) so electronics can be dropped onto the back of polypropylene labels to create the flashing beer bottle or similar, assuming one can find a battery to power it and an LED to light up.
