Hobbyist Gives iPhone 7 the Headphone Jack We've Always Wanted (engadget.com) 194

intellitech shares a report from Engadget: For those of you who miss the iPhone headphone jack, you're definitely not alone. But Strange Parts creator Scotty Allen missed it so much that he decided to add one to his iPhone 7. He just posted a video of the project's entire saga, with all of its many ups and downs, and in the end he holds what he set out to create -- a current generation iPhone with a fully functional headphone jack. It turns out, real courage is adding the headphone jack back to the iPhone. The project took around 17 weeks to complete and throughout it Allen spent thousands of dollars on parts including multiple iPhones and screens and handfuls of lightning to headphone adaptors. Along the way, Allen bought a printer, a nice microscope and fancy tweezers. He had to design his own circuit boards, have a company manufacture multiple iterations of flexible circuit boards and at one point early on had to consult with a chip dealer that a friend hooked him up with.

The final product works by using a lightning to headphone adaptor that's incorporated into the internal structure of the phone. However, because the headphone jack is powered via the phone's lightning jack with a circuit board switching between the two depending on whether headphones or a charger are plugged into the phone, you can't actually listen to music and charge the phone at the same time.

How LEDs Are Made 93

An anonymous reader writes "The SparkFun team took a tour of a factory in China that manufactures LEDs. They took lots of pictures showing the parts that go into the LEDs, the machines used to build them, and the people operating the machines. There's a surprising amount of manual labor involved with making LEDs. Quoting: 'As shipped on the paper sheets, the LED dies are too close together to manipulate. There is a mechanical machine ... that spreads the dies out and sticks them to a film of weak adhesive. This film is suspended above the lead frames ... Using a microscope, the worker manually aligns the die, and, with a pair of tweezers, pokes the die down into the lead frame. The adhesive in the lead frame wins (is more sticky), and the worker quickly moves to the next die. We were told they can align over 80 per minute or about 40,000 per day.'"

Electronic Tweezers Grab Nanoparticles 13

MTorrice writes "A beam of electrons can pick up and carry nanoparticles, according to a new study (abstract). The so-called electronic tweezers could help scientists in diverse tasks, such as building up new materials nanoparticle-by-nanoparticle, and measuring the forces between nanoparticles and living cells, the researchers say. In the past, scientists have manipulated microsized particles, including single cells, using a beam of laser light called optical tweezers. But the force required to trap a particle with optical tweezers increases as the particle gets smaller, making grappling with nanoparticles difficult. Researchers at Lawrence Berkeley National Laboratory developed an alternative to optical tweezers by modifying a transmission electron microscope, which produces images by passing a stream of electrons through a sample." Reader Sven-Erik adds news of a tractor beam generated with laser light that can pull microscopic particles over distances of 30 micrometers (abstract).

NASA Wants To Make Tractor Beams a Reality 91

intellitech sends this quote from a NASA news release: "Tractor beams — the ability to trap and move objects using light — are the stuff of science fiction, but a team of NASA scientists has won funding to study the concept for remotely capturing planetary or atmospheric particles and delivering them to a robotic rover or orbiting spacecraft for analysis." Reader Bob the Super Hamste adds, "The article along with the BBC's coverage discuss briefly three methods of how this can be done with lasers. The first method called 'optical tweezers,' in which a molecule is trapped where two beams cross (PDF). However, it requires an atmosphere to work. The second method using solenoid beams has already worked in the laboratory (PDF). The third method using Bessel beams has yet to be experimentally proven."

Tractor Beams Come To Life 127

Jamie is helping bring our childhood fantasies/nightmares to life with a link that says "Andrei Rhode, a researcher involved with the project, said that existing optical tweezers are able to move particles the size of a bacterium a few millimeters in a liquid. Their new technique can move objects one hundred times that size over a distance of a meter or more."

Frank Zappa's Influence On Linux and FOSS Development 195

Roblimo writes "Zappa's 'Dinah-Moe Hummm' is totally about Linux, at least in spirit, while the song 'Montana,' with its talk of zirconium-encrusted tweezers and dental floss, 'is obviously about Mac users.' Not only that: In the early '70s Zappa wrote a song called 'Penguin in Bondage,' an obvious foretelling of the anti-Linux lawsuits and threats from SCO, Microsoft, and other evildoers. Zappa was also a heavy user of the Synclavier, an electronic music machine that was a precursor to today's 'studio on a computer' recording and sound editing software. According to an article on DevX, today Zappa would no doubt be using Linux and Ardour for most of his recording and composition."

High-Speed Robot Hand Shows Dexterity and Speed 133

An anonymous reader tips a blog posting that begins "A few blogs are passing around videos of the Ishikawa Komuro Lab's high-speed robot hand performing impressive acts of dexterity and skillful manipulation. However, the video being passed around is slight on details. Meanwhile, their video presentation at ICRA 2009 (which took place in May in Kobe, Japan) has an informative narration and demonstrates additional capabilities. ... [It] shows the manipulator dribbling a ping-pong ball, spinning a pen, throwing a ball, tying knots, grasping a grain of rice with tweezers, and tossing / re-grasping a cellphone!"

Miniaturized DNA Sewing Machines 75

Roland Piquepaille writes "Japanese researchers have found a way to build long threads of DNA using miniaturized hooks and bobbins. In fact, they've demonstrated how to manipulate delicate DNA chains without breaking them. They've designed these laser-directed microdevices to pick up and manipulate individual molecules of DNA. The scientists have used optical tweezers to catch and move these microdevices, which could be used in the future to detect genetic disorders such as Down syndrome." Here's a link to the journal article.

'Laser Tweezers' Used to Sort Atoms 92

luckyguesser writes to tell us that Physicists at the University of Bonn are claiming to have knocked down one more quantum computing hurdle. Utilizing what they term "laser tweezers" they were able to sort and align seven atoms while capturing it on film. The plan is to construct a quantum gate using atoms imprinted with data.

Holographic Laser Tweezers To Manipulate Cells 22

SteamyMobile writes "How do you move things as small as single cells? Using tweezers, of course, but not just any tweezers. These tweezers must be holographic laser tweezers, developed at the University of Glasgow and Oxford University. These tweezers use a hologram to structure a light source in such a way as to exert just enough gentle pressure to move a cell. First, they use light to move water, and now this. I can think of some applications, too."

Micromachines Powered by Light 4

Chris writes "Hungarian researchers succeed in controlling the rotation of micromachines that are powered by light. They have succeeded in reversing the rotation of a micro-rotor trapped in optical tweezers. The crucial element of this system is an oil-immersed objective lens with a very high numerical aperture. Changing the position of the objective lens controls the direction of rotation. The team now hopes to make complex integrated systems where all the components of a micromechanical system are integrated. This could find applications such as measuring the properties of large biological molecules and making components such as miniature pumps and actuators for lab-on-a-chip devices."

How Can You Straighten HDD Pins? 66

racerx509 writes: "I just did something thats probably going to cost me much. I was reinstalling my hdd after trying to ghost the partition for another pc, when I jammed the cable in wrong. The cable is keyed and the keyed side was in correctlty, so I figured that it was going in right. However, I have severly bent several of the pins. The HDD will no longer detect even after I attempted to straighten the pins. Pin #11 has receded into the aperature and pins #15 and #16 are seriously bent. I've straightened them out with tweezers as much as I can, but it looks like this drive is gone. I would replace it, but i have some very important data on it. Does anyone know of a way I could straigten the pins and pull receded ones? If not, what about a good data recovery service in the Atlanta area?"

Tweezers Of Light 7

jasonripp writes: "Seems those wacky scientists have discovered a method to use light to easily move tiny particles of matter with a high degree of precision. This has applications in biotech, computers and more. The article is here." It's one of those cool low-tech inspirations, too -- the "light tweezers" these scientists have devised were inspired by cheap laser-pointer accessories.
