Taking macros of your monitor or American Apparel hoodie with your iPhone is so last year.

A Make Magazine tutorial shows you how to make a powerful microscope with up to 375x magnification using just your iPhone, a clear plastic panel, a piece of plywood and some inexpensive hardware.

If you’re a DIY-er that knows how to drill holes and take apart a laser pointer on a keychain, you could be taking super up-close pictures of cricket legs and your cat’s tongue before you know it.

There are millions of asteroids in the Solar System and relatively few astronomers to track them. They’d hate to miss that one dangerous rogue headed on a collision course with Earth.

So NASA has made it easier for the amateur stargazer to record and compare their discoveries and put extra eyes on the asteroid belt between Mars and Jupiter.

NASA and Planetary Resources Inc. have developed a computer program that is based on an algorithm that analyzes images for potential asteroids. The new asteroid hunting application, available for free download here, was announced Sunday by NASA at the South by Southwest Festival in Austin, Texas.

New snail species is so punk, it’s named after Joe Strummer

This deep sea snail is covered in spikes, has purple blood and lives in the most extreme ocean environments. So of course the scientists that discovered it had to name it after their favorite punk rocker, Joe Strummer of The Clash.

In a study cleverly named “Molecular taxonomy and naming of five cryptic species of Alviniconcha snails (Gastropoda: Abyssochrysoidea) from hydrothermal vents,” researchers at the Monterey Bay Aquarium Research Institute detail five new species of snails, one of which gained the scientific name A. strummeri to honor The Clash frontman.

An iPad filled with apps weighs more.

Which weighs more? An iPad filled with media and apps, or an iPad with no media or apps installed?

It sounds like a trick question — the digital age equivalent of “What weighs more, a pound of feathers or a pound of rocks?”

But surprisingly, an iPad without anything installed on it does weigh less than an iPad that is full.

RoboRoach Lets Kids Turn Real Cockroaches Into iPhone-Controlled Cyborgs

By

roboRoachGoRight

 

Robots are pretty cool, but have you ever wanted to create your own iPhone controlled cyborg? Backyard Brains is banking that a lot of kids are interested in cyborg technology and neuroscience (ethical dilemmas be damned), so after three years of R&D they’ve come up with the RoboRoach – a small electronic surgery kit that lets you turn a real-life cockroach, into an iPhone-controlled cyborg for a few minutes.

The kit comes with a backpack that contains a battery and receiver you superglue to the cockroach after sanding down a patch of shell.  You have to jab a groundwire into the cockroaches thorax, and then after that you carefully trim the antenna so you can stick some small electrodes onto both of them and receive signals from your iPhone. Don’t worry, the iPhone app and the cockroaches come free with the $99 kit, so you don’t have to go hunting for some behind your supermarket’s dumpster.

Usually when we mention a Kickstarter project it’s with a mixture of excitement (because it’s like a totally cool product) and disappointment (because it will usually be at least half a year before we see a product, if ever).

However, some of these products make it into stores. The Vaavud is one. It’s a no-power wind-meter which you can buy today.

Scientist Transforms iPhone Into A Microscope Using Lens That Only Costs 7 Bucks

All it takes is some double sided tape and a $7 lens to turn your iPhone into a microscope

Add microscopes to the list of things your iPhone can replace. A group of scientist visiting Tanzania were able to convert their iPhone 4S into a microscope using nothing by a $7 lens, some double sided tape, and a torch.

After macgyvering the iPhone 4S into a microscope, the scientest then used it to take pictures of stool samples to determine the presences of eggs in some schoolchildren. Amazingly, the iPhone picked up 70 percent of the infections.

Question: What’s the only (non-gimmicky) photographic filter that can’t be duplicated in software? That’s right, you smart genius you! It’s the polarizer. A polarizer will do two things for your photography: it’ll increase the saturation of the colors in your pictures, and it’ll cut out unwanted reflections from glass and water. And Photojojo will now sell you one that’ll clip right onto your iPhone.

New From Microsoft: Multitouch In Mid-Air

Wave your hands in the air like you just don't care

Researchers in the UK have put together a prototype wrist-worn sensor that turns your own hand into a 3D movement controller for almost any device you can think of.

Experts from Newcastle University and the Cambridge-based Microsoft Research used off-the-shelf parts to assemble a sensor that straps to your wrist and detects movement of your arm, hand and fingers. There’s no need for any external sensor, nor for line-of-sight to the device you’re controlling. Everything’s done using the technology you wear.

Here’s a video that explains more.

How Super Algorithms Will Make Future iPhones & iPads Charge Twice As Fast

By

0243.iPadCharging_77FC8044

Plug in your iPhone or iPad and charge it up, and you’ll notice that while the first 80% or so will go by pretty fast, they actually kind of suck at charging up that last 20%, taking a lot more time to do so than it feels like they should.

There’s a reason for this. Charging batteries up to “full” is a complicated process. There’s no real way to tell if a battery is completely “full” so all you can do is measure the voltage, which (and this is a vast simplification) tells you how much resistance is being met when you try to put more electricity into the battery.

That’s why it takes so long for an iPhone to charge that last 20%. It charges full blast until it measures a certain voltage, then goes into what’s called “trickle mode” to slowly allow small sips of electricity into the battery until it thinks, based upon some software calculations, that the battery is more or less full. But a new algotihm could make the time it takes to charge your iPhone or iPad go by a lot faster.

Neatomo Turns Your iPhone Into A Weather Station

When I was a cub scout, I made my own backyard weather station. It was to get my science badge, or weather nerd badge, or whatever, and it mainly consisted of counting the millimeters of rain in a jamjar with an oversized plastic funnel perched on the top. And there was always rain: This was England.

If I’d had access to the wonderful technology of today, though, I could have stayed in watching TV and let the Netatmo do the work for me. The Netatmo is a weather station for both indoors and outdoors, and is sold as something that will stop you from worrying about your children and — therefore — the future.

10,000 PPI Image Makes Retina Look Like Mr. Magoo’s Wallpaper

This is the highest-resolution image that could ever be made.

What resolution is Retina resolution? 220 ppi (like the new MacBook Pro)? 264 ppi (like the iPad 3)? Or the amazing 326 ppi found on the iPhone?

What about 10,000 ppi? That’s the resolution of an image printed by researchers at the Agency for Science, Technology and Research in Singapore. It’s the picture you see above which, at just 50 x 50 microns, is the same size as a single pixel on an Apple Retina display.

MIT Video Tech Could Turn iPhones Into Real Life Tricorders

Imagine that you could just point your iPhone’s camera at your baby and it would immediately tell you his vital signs: heartbeat and so on. Or that you could fire up an app and it could pick out tiny, invisible movements from what looks like a still video. Using a process called Eulerian Video Magnification, boffins at MIT are doing this already.

MIT Students Create The Future With An iPad And A Glove

By

Collaboration

You’ve seen Stephen Spielberg’s film, Minority Report, right? Tom Cruise’s character stands in front of virtual screens, puts on a pair of gloves, and manipulates the data and the memories without touching a thing. Well, the super brains at MIT’s media lab have taken the first step toward that reality, using Apple’s magical device as a display screen and a special glove/attachment combo to interact with it.

The video the group has released shows some pretty fancy stuff, drawing objects in 3D real time, and then manipulating them in collaboration with others. There’s even some slick Minority Report-style interface there, with researches moving red and blue rectangles around in the virtual space they’ve created on the iPad.

This iOS App Blows Your Mind In Four Dimensions [Review]

Watch out for the cuboid shadow of the 4D object later on

If, like many people, you find Mondays just too much to cope with, you might want to avoid today’s app. It’s not the sort of thing that’s going to make your Monday feel any better, and in some cases it will just fry your brain until next Monday. Which would be a shame, because you’d miss out on a whole weekend.

Be forewarned, then: The Fourth Dimension is an app which will mess with your head. Deliberately. Even though the aim is education and expansion of knowledge, it will still mess with your head. You will emerge from the experience only fractionally the wiser, and quite a lot more confused than you were at the beginning. Don’t worry, this is perfectly normal.

Analog Joystick Works Via iPhone Camera

The Fling controller from TenOne Design (soon to be reviewed) is a great way to add a physical to your iPhone or iPad, just by suction-cupping it onto the screen. This means that it works with any game on your iOS device that uses an on-screen “joystick.”

The downside is that it moves at the worst moments: I have wiped out in more than one GTA car chase this way. But designers at the Keio University in Japan have come up with another idea. A joystick which uses the iPhone’s camera as a controller.

If you’re frustrated that your app was rejected from the App Store, you are in good company.

Scott Virkler, senior vice president of eProducts at global science and medical publishing behemoth Elsevier, had a few choice words about Apple’s approval process – and getting rejected by it.

Virkler, speaking in San Francisco at Appnation Enterprise, said his company had three apps rejected by Apple just last week, “because they don’t get our business.”
