Love low-fi? 3D-print your own vinyl records

I can't bear to part with my record collection. It's got gems like Steely Dan's "The Royal Scam" that sound better on a turntable and amplifier than on MP3.

Maybe analog sound can feel better because we're analog creatures. Whatever the reason, vinyl's recent popularity has led to events like Record Store Day and DIY projects like Amanda Ghassaei's 3D-printed records.

An editorial staffer at Instructables.com, Ghassaei managed to lay down digital audio files on 3D-printed 33 rpm records that she played on a standard turntable.

The results, as heard in the video below, sound about as clear as phonograph cylinders from the 1880s. The audio output has a sampling rate of 11kHz and 5- to 6-bit resolution, but tunes like Nirvana's "Smells Like Teen Spirit" are easily recognizable.

Ghassaei went to TechShop in San Francisco and created the records on a large-scale Objet Connex500 printer, which has a particularly high 600dpi X and Y resolution and a print layer accuracy of 16 microns.

It produced records with grooves that are wider and deeper than factory-made vinyls, so each side can only fit five or six minutes of sound. Check out a video of Ghassaei removing the white resin records from the printer, pizza-style, and scraping off the residue here.

She notes that her 3D-printed copy of Daft Punk's "Around the World" had such a heavy bass sound that it threw the needle off and forced her to revise the conversion algorithm. Meanwhile, you can download her other printed songs like New Order's "Blue Monday" here.

"The Objet still at least an order of magnitude or two away from the resolution of a real vinyl record," Ghassaei writes. "My hope with this project was that despite the lack of vinyl-quality precision, I would still be able to produce something recognizable by approximating the groove shape as accurately as possible with the tools I had."

Her homespun records are only prototypes and who knows how good they'll get. Could this lead to a DIY K-tel?

Get 'em While You Can? Gun Sales Soar

The National Rifle Association may still get its way and defeat the lawmakers calling for a ban on the sale of assault ridles, but some gun store owners say it seems their customers aren't taking any chances.

"We have never seen anything like this," said Larry Hyatt, who owns a gun shop in Charlotte, N.C. "We have the Christmas business, the hunting season business, and now we have the political business.

"We have seen a lot of things, but we have never seen anything like this, this is probably four times bigger than the last time we saw a big rush," he said.

Some of the customers in his store said it is the talk of stricter gun control in the wake of the shooting at the Sandy Hook Elementary School in Newtown, Conn., that is driving the rush.

"The way they are trying to approach it, they are just making people who have never thought about buying a gun, now they want to come in here and buy a gun," one customer said.

At NOVA Firearms in Falls Church, Va., there have been "skyrocketing" sales following the Newtown shooting, chief firearms instructor Chuck Nesby said.

"They've been off the charts. Absolutely skyrocketing," Nesby said. "If I could give an award to President Obama and Senator Feinstein would be sales persons of the year."

He was referring to Sen. Dianne Feinstein, D-Calif., who said she will introduce an assault weapons ban in January.

Sales are up 400 percent, he said.

"We're completely out of the so-called assault weapons, semi automatic firearms that are rifles," Nesby said. "Forty percent of those sales went to women and senior citizens. We can't get them now. Everybody, nationwide is out of them the sales have just been off the charts nationwide."

National Rifle Association News Conference Interrupted by Protesters Watch Video

The horrific shooting, when 20-year-old Adam Lanza broke in to the elementary school and killed 20 children and six adults with a semi-automatic rifle, has even some former NRA supporters saying it's time to change the rules on assault weapons.

Those guns were banned from 1994 until 2004, when the ban expired and was not renewed.

Now it's not just lawmakers who have traditionally advocated stricter gun control talking about the need to act.

Republican Sen. Kay Bailey Hutchison of Kansas suggested today on CBS' "Face the Nation" that new regulation should be considered.

"We ought to be looking at where the real danger is, like those large clips, I think that does need to be looked at," Hutchison said. "It's the semi-automatics and those large magazines that can be fired off very quickly. You do have to pull the trigger each time, but it's very quick."

Virginia Sen. Mark Warner, a Democrat but a long-time opponent of gun control who like Hutchison has received an A rating from the NRA, has also come out in support of strengthening gun laws.

NRA chief Wayne LaPierre said Friday that more gun control is not the way to stop such shooting from happening again: the answer is more guns, in the form of armed guards in every school.

After being criticized for two days for the proposal, LaPierre today stuck by his guns.

"If it's crazy to call for putting police and armed security in our schools to protect our children, then call me crazy," he said on NBC's "Meet the Press."

"When that horrible monster tried to shoot his way into Sandy Hook school, that if a good guy with a gun had been there, he might have been able to stop [it]," LaPierre said.

LaPierre and the NRA said that the media, the entertainment culture and lack of proper mental health care are to blame, not the proliferation of guns in the United States.

Asa Hutchinson, the former congressman who will lead the effort by the NRA to place armed security guards in schools across the country, said today on "This Week" that gun control efforts would not be part of the "ultimate solution" to gun violence.

Sydney Harbour floating heliport plan on hold

SYDNEY: A plan for wealthy executives and tourists landing in Sydney to flit directly to the city's famous harbour via a floating heliport has been put on hold after fierce public opposition.

The company that was set up to run the operation, providing for quick transfers to and from Sydney airport and scenic flights over the harbour, said it wanted to further consider the operation's "feasibility".

"It is Newcastle Helicopter's intention to address the relevant concerns and queries with thoroughly considered and accurate information, and is taking the appropriate steps to do so," it said in a statement late Saturday.

It followed rising public anger over the New South Wales state government giving the go-head last month to unlimited flights from a barge anchored on the harbour, which is popular for yachting and close to residential areas.

According to reports, the Roads and Maritime Services (RMS) issued the licence without consulting the community, doing an environmental impact assessment, testing for noise, or putting the project out to tender.

The Sydney Morning Herald also claimed approval was given two weeks before authorities asked about air safety or air traffic control regulations.

New South Wales Deputy Premier Andrew Stoner last week insisted all usual procedures had been followed.

"As required by RMS, the proponent wrote to relevant councils in October outlining the proposal and inviting feedback but received no responses," he said in a statement.

Federal MP Malcolm Turnbull led the campaign against the heliport and said the decision had descended into farce.

"If you put this into an episode of 'Yes, Minister', nobody would believe it," he told reporters, referring to the satirical British comedy show, which revolves around the inner workings of government.

Industry leaders have long called for a heliport based in the city, which last had one in the late 1980s operating from the Darling Harbour tourist precinct.

Pictures: Fungi Get Into the Holiday Spirit

Photograph courtesy Stephanie Mounaud, J. Craig Venter Institute

Mounaud combined different fungi to create a Santa hat and spell out a holiday message.

Different fungal grow at different rates, so Mounaud's artwork rarely lasts for long. There's only a short window of time when they actually look like what they're suppose to.

"You do have to keep that in perspective when you're making these creations," she said.

For example, the A. flavus fungi that she used to write this message from Santa grows very quickly. "The next day, after looking at this plate, it didn't say 'Ho Ho Ho.' It said 'blah blah blah,'" Mounaud said.

The message also eventually turned green, which was the color she was initially after. "It was a really nice green, which is what I was hoping for. But yellow will do," she said.

The hat was particularly challenging. The fungus used to create it "was troubling because at different temperatures it grows differently. The pigment in this one forms at room temperature but this type of growth needed higher temperatures," Mounaud said.

Not all fungus will grow nicely together. For example, in the hat, "N. fischeri [the brim and ball] did not want to play nice with the P. marneffei [red part of hat] ... so they remained slightly separated."

Obama, Congress Waving Bye-Bye Lower Taxes?

The first family arrived in the president's idyllic home state of Hawaii early today to celebrate the holidays, but President Obama, who along with Michelle will pay tribute Sunday to the late Sen. Daniel Inouye at the National Memorial Cemetery of the Pacific, could be returning home to Washington sooner than he expected.

That's because the President didn't get his Christmas wish: a deal with Congress on the looming fiscal cliff.

Members of Congress streamed out of the Capitol Friday night with no agreement to avert the fiscal cliff -- a massive package of mandatory tax increases and federal spending cuts triggered if no deal is worked out to cut the deficit. Congress is expected to be back in session by Thursday.

It's unclear when President Obama may return from Hawaii. His limited vacation time will not be without updates on continuing talks. Staff members for both sides are expected to exchange emails and phone calls over the next couple of days.

Meanwhile, Speaker of the House John Boehner is home in Ohio. He recorded the weekly GOP address before leaving Washington, stressing the president's role in the failure to reach an agreement on the cliff.

"What the president has offered so far simply won't do anything to solve our spending problem and begin to address our nation's crippling debt," he said in the recorded address, "The House has done its part to avert this entire fiscal cliff. ... The events of the past week make it clearer than ever that these measures reflect the will of the House."

Senate Minority Leader Mitch McConnell echoed the sentiment while lamenting the failure to reach a compromise.

"I'm stuck here in Washington trying to prevent my fellow Kentuckians having to shell out more money to Uncle Sam next year," he said.

McConnell is also traveling to Hawaii to attend the Inouye service Sunday.

If the White House and Congress cannot reach a deficit-cutting budget agreement by year's end, by law the across-the-board tax hikes and spending cuts -- the so called fiscal cliff -- will go into effect. Many economists say that will likely send the economy into a new recession.

Reports today shed light on how negotiations fell apart behind closed doors. The Wall Street Journal, citing unnamed sources, reported that when Boehner expressed his opposition to tax rate increases, the president allegedly responded, "You are asking me to accept Mitt Romney's tax plan. Why would I do that?"

The icy exchange continued when, in reference to Boehner's offer to secure $800 billion in revenue by limiting deductions, the speaker reportedly implored the president, "What do I get?"

The president's alleged response: "You get nothing. I get that for free."

The account is perhaps the most thorough and hostile released about the series of unsuccessful talks Obama and Boehner have had in an effort to reach an agreement about the cliff.

Unable to agree to a "big deal" on taxes and entitlements, the president is now reportedly hoping to reach a "small deal" with Republicans to avoid the fiscal cliff.

Such a deal would extend unemployment benefits and set the tone for a bigger deal with Republicans down the line.

In his own weekly address, Obama called this smaller deal "an achievable goal ... that can get done in 10 days."

But though there is no definitive way to say one way or the other whether it really is an achievable goal, one thing is for certain: Republican leadership does not agree with the president on this question.

Of reaching an agreement on the fiscal cliff by the deadline, Boehner said, "How we get there, God only knows."

Football: Barca battle on without Vilanova for time being

MADRID: Barcelona will have to continue their march at the top of La Liga without Tito Vilanova after it was revealed the coach has suffered a relapse of a tumour on which he was operated just over a year ago.

The 44-year-old who took over from Pep Guardiola at the beginning of the season was thought to have fully recovered from surgery last November to remove the growth on his parotid gland, and he was back at work within 15 days.

However after an operation on Thursday it is thought he will have treatment for at least six weeks and he may or may not be available to return to work at some stage during that time.

Until then, Sporting director Andoni Zubizarreta confirmed on Thursday, the side will be led by Vilanova's assistant Jordi Roura.

"Without going into too much detail about the sporting side today and whether we win or not at Valladolid on Saturday, just to say we'll continue with our coaching staff and our way of working, we'll be in extraordinary hands and Tito I'm sure will be watching us on TV," he said.

Barca president Sandro Rossell added "the most important thing for the club at this moment is the full recovery of Tito".

Vilanova has led Barcelona to the most successful start to a season in La Liga's history, with 15 wins and one draw in 16 matches so far.

With the final round of La Liga games of 2012 brought forward to allow the players an extra day of Christmas holidays, Barca will make it a great finish to the year, on the pitch at least, if they take three points at Valladolid.

Last weekend's win over closest rivals Atletico Madrid increased the Catalan side's lead to nine points and with Real Madrid's surprise draw with Espanyol leaving them 13 points back in third, for some La Liga title is already destined for the Nou Camp in May.

That win was followed with the news on Monday that Carles Puyol and Xavi Hernandez will stay at Barca until at least 2016 and Lionel Messi until 2018, and it was all looking positive until Wednesday's shock news.

Last Sunday's clear dominance over their closest rivals Atletico Madrid, especially in the second-half of the 4-1 win, left most observers concluding that it is the Catalan side's title to lose.

Meanwhile, Real Madrid face a tricky trip to fourth placed Malaga less than a week after manager Jose Mourinho said the title was "almost impossible now".

Defeats at Getafe, Sevilla and Betis, followed by the draw with Espanyol last Sunday, have left Madrid far adrift from table-toppers Barca.

One player the 'Merengues' missed last Sunday was French forward Karim Benzema.

Benzema is closer to a return than colleague Gonzalo Higuain, but could still miss the trip to Malaga with a foot injury. However he has pledged his future to the club this week, despite his name being linked with Paris Saint-Germain.

Malaga come into the game with the best defensive record in the league having conceded only 10 goals in 16 games and full-back Nacho Monreal is confident.

"We're going to be up for the Madrid match, we're doing well, we're at home and we know that Madrid is not going too good, but they're a good team and it will be difficult. I just hope we can take our chances and get the three points," he said.

In this week's matches already played, Rayo Vallecano beat Levante 3-0, Real Sociedad edged Sevilla 2-1 and Espanyol defeated Deportivo La Coruna 2-0, on Thursday.

On Friday, substitute Adrian Lopez hit an important winner as Atletico Madrid beat Celta Vigo 1-0.

Their win, Atletico's ninth straight victory at home this season, moves the club from the capital to within six points of Barca, in second position.

Earlier on Friday, Valencia beat Getafe 4-2 at home to make it two wins out of three for new manager Ernesto Valverde.

Saturday's fixtures:
Betis v Mallorca (1500 GMT), Valladolid v Barcelona (1700 GMT), Osasuna v Granada (1900 GMT), Malaga v Real Madrid (1900 GMT), Athletic Bilbao v Zaragoza (2100 GMT)

Why does my external hard drive only show 2.2TB?

External hard drives are exceptionally useful for expanding storage capabilities for both backups and data management. While external hard drives are often sold in preconfigured packages by manufacturers, another popular option is to purchase an external hard-drive enclosure and then use any drive of your choice in it. This is beneficial because as your demands for storage increase, you can replace the enclosure's drive with a larger one.

These days, the availability of hard drives with 4TB of storage are enticing for people to swap into their existing enclosures; however, when doing so they may find that the system will only recognize 2.2TB of the drive, regardless of how they partition or format the device.

While modern file-system formats such as HFS+, NTFS, and ExFAT ought to handle volume sizes of between hundreds of gigabytes to zettabytes, and though operating systems like OS X have increased the maximum volume size from 2TB to 8EB (exabytes) over the years, there are hardware limitations that may limit the size of the volume that can be used. If you are using an older drive enclosure for your large hard drive, then the controllers on it may not be capable of handling over 2.2TB, regardless of the software environment being used around it.

This problem happens because of the use of LBA (logical block addressing) in modern hard-drive controllers coupled with a hardware-based limit of how many blocks can be included in the LBA scheme. Early LBA controllers used 32-bit (or lower) addressing coupled with a maximum supported block size of 512 bytes. This means they support up to 2^32 or 4,294,967,296 blocks for a device, and with each block being 512 bytes, this translates to a maximum of 2,199,023,255,552 bytes, or 2.199TB.

Unfortunately in many cases these limits are hard-coded in enclosure's firmware, so even though modern drives use 4,096-byte sectors, the system will still only address these sectors as 512 bytes in size, resulting in both a waste of space and degraded performance.

The only way around this problem is to replace your drive enclosure with a new one that has proper support for both 48-bit (or greater) LBA and 4,096-byte sectors in hard drives. Luckily most enclosures on the market today do support this, so if you run into this problem, you should be up and running in no time.
