OlloClip iPhone 4/4S Lens Review

OlloClip iPhone 4/4S Lens Review
One of the iPhone 4/4S camera’s shortcomings is its fixed lens with narrow field of view and mediocre macro capability. That’s where the OlloClip comes in! This little guy packs three lenses into one: A 180-degree Fisheye, Wide-angle that doubles the iPhone’s field of view and a Macro that offers a 10x magnification and can shoot from a mere 12mm away from the subject. Not only does the OlloClip look badass and will score you dates, but it comes in a nifty little carrying sack and two different colors. Did the OlloClip survive my ruthless digital imaging tests? Read on to find out.

OlloClip Design
The OlloClip is a niftily engineered little contraption. First off, it comes in black or a red/black two-tone scheme, and I think red is the sexier of the duo. With that out of the way, the OlloClip fits iPhone 4/4S models and nothing else–sorry Androidians! True to its name, the OlloClip is actually a plastic clip sandwiched by two lenses–a wide-angle and larger fisheye. However, unscrewing the wide-angle lens reveals a third lens, the OlloClip’s Macro glass. The clip slides onto the top right corner of the phone, naturally fitting over the iPhone’s built-in lens.
Here’s the thing about the OlloClip. Its design prohibits the use of the Lockscreen button. This could have been remedied by adding a spring-loaded external lock button on the clip portion of the apparatus. But, we don’t get that luxury and must remove the OlloClip in order to wake the phone up or put it to sleep. That’s okay though, for any devout photographer is accustomed to a few extra steps with interchangeable lenses, memory cards and battery packs, so this is a minor issue.
The OlloClip comes with two lens caps and a carry sack. It’s fairly compact, but not something that would fit comfortably in a pocket. I kept the OlloClip in my backpack or jacket pocket and that did the trick. Luckily, the OlloClip sack’s microfiber fabric doubles as a lens wipe, which is essential since the smaller optics risk inadvertent fondling and fingerprints during repeated iPhone application.

The Fisheye Lens
Let’s buckle down the specifics of each lens. The Fisheye is the most aggressive of the trio, converting that conventional iPhone lens into a 180-degree field of view piece of spheric optic goodness. The Fisheye is ideal in tight situations like a cramped store or packed corner, but its striking globe-like effect is best suited for taking artistic images. I loved the Fisheye lens for its ability to transform the iPhone’s lens into a completely different set of optics and its range was so great that I actually had to keep my fingers off the back of the phone or else they’d end up in the shot.
Now for the wide-angle. This lens will approximately double the wide-angle capability of the iPhone’s lens, allowing you to pack a lot more into your shots without stepping back. Wide-angle lenses are traditionally geared toward family portraits, landscapes and depth manipulation. Objects in the foreground will look closer and larger than they actually are, therefore the wide-angle lens can be used in artistic situations as well as the Fish-eye, though the field of view on the wide-angle is not nearly as drastic.
Last up we have the Macro lens, which can be accessed by unscrewing the Wide-angle lens. The Macro lens was by far my favorite member of the trio, courtesy of its superhero strengths. We’ll start with its 10x magnification multiplier, which enables the OlloClip’s Macro lens to focus from a mere 12-15mm of the subject. It was scary how close I was able to focus–it was like taking pictures with a microscope. Check out the image samples taken with the Macro lens. They are insane.
OlloClip Quality
Here’s the deal. The OlloClip is as freaking fun as the day is long on a double shift. The Macro lens is by far the OlloClip’s strongest performer with its flabbergasting 10x magnification. The image quality is fantastic, along with the Macro’s ability to adequately define an amoeba. If you’re curious as to what certain materials look like under a small microscope, use the Macro lens.

How to turn your iPhone into a microscope eyepiece

How to turn your iPhone into a microscope eyepiece
Sometimes people ask me to look at frightfully exciting things.
These normally come via the incomprehensible medium of the press release. However, sometimes I get sent things (in this case, via an e-mail from my louche engineer friend George) describing a new invention that seems positively useful and even vaguely comprehensible.
This thing is called the SkyLight. It allows you to take your iPhone, Android phone, or any other that might still exist and turn it into a microscopic eyepiece for the world.


Its creator is medical designer Andy Miller. He has already designed the Global Focus microscope, a light, cheap fluorescent microscope for developing countries.
However, as he describes in the Kickstarter presentation I have embedded, his aim with the SkyLight is to allow trained medical practitioners to remotely view images from microscopes.
Miller says that almost any microscope--however old--can benefit from having a SkyLight attached to a smartphone in order to transmit excellent, and possibly even life-saving, images.
The device itself seems simple--in the way that comprehensible things often do. It clamps the smartphone camera over the microscope's eyepiece in order to capture the vital (or merely educational) images.
The SkyLight comes with various attachments so that it can be adjusted to any size of eyepiece.
Miller shows in the Kickstarter video that the images can be shared via Face Time or other video conferencing apps.
He has already raised almost $4,000 of the $15,000 he says he needs in order to go into production.
To my layman's eyes, this thing--unlike so many inventions--seems absurdly useful. What's most powerful about the idea, though, is that it's useful to those who might not have the benefits of modern medical technology at their disposal.
If something this simple can capture just one disease in time--thereby saving a life--it will truly make any Jesus phone, well, a little more saintly.

Family under the microscope

Family under the microscope
In choosing primary schools, parents take many things into account. If educational success is prioritised, then the calibre of the head teacher and the proportion of children in the school from low-income homes (and without English as a first language) are important. Unfortunately, these latter tend to need more help, eating into the time devoted to other pupils. But perhaps the most significant single issue is class size, not social class.
This is not simply a matter of measuring teacher-pupil ratios. Some classes are small because low-performing pupils have been clustered together to give them a better chance. Experimental studies are a better test; the best being one done in Tennessee.
Pupils and teachers in the same school were randomly assigned to three class types. One class had 17 pupils, another had 23, a third had the same number but with the addition of a teaching assistant. The children in the small classes did significantly better in maths and reading, with those from ethnic minorities benefiting the most. The children were returned to normal classes from grade 4 (year 6) onwards, but the improvements were still evident three academic years later.
Other evidence comes from a longitudinal British study that tracked more than 10,000 pupils in 300 schools from entry to the end of primary. Care was taken to measure factors other than class size that could influence outcomes. Small classes (under 25) had a significant effect on literacy and maths in the first year. This effect endured for literacy (but not maths) in the second year. However, the literacy effect disappeared by the third year, as many of the pupils moved into larger classes.
Tellingly, the effect of first year small classes carried over into the second year more when children moved into a similar or smaller class. Moving to a larger class had a negative effect.
The study also showed why small is beautiful. Teachers spent more time with pupils, individually; the classes were easier to control; and more time could be spent in planning and marking work. Consequently, pupils are better behaved and are more engaged in the process of learning. They asked more questions, discussed subjects with teachers, and were more inquisitive. While bad teachers are not made good by small classes, and while there is a danger that teachers with small classes sometimes fail to adapt their techniques to individualise the pedagogy (having been trained to deal with large ones), particularly for the early years, small is definitely best.
Interestingly, there is little evidence that teaching assistants improve educational outcomes. While they do free up the teacher to provide more individualised attention, they do not have the same effect as simply having smaller classes: results in maths and literacy are not improved by having teaching assistants.
Arguably, class smallness is the main educational asset you buy for your child by going private. It is deeply regrettable that the last government did not take the evidence on board.
Rather than saving money by injecting teaching assistants into schools and by squandering billions on private sector partnership building programmes, they could have increased the number of teachers and reduced class sizes. With Cameron cutting education, it is hardly likely he will be splashing out on this. So, alas, it means that if you want the best for your child, you have to seek out the state school nearest to you with the smallest class sizes and, I am sorry to say, the most other middle-class children. That's always assuming you reject the private sector on principle or for financial reasons, or cannot face the idea of home education.

Spy pen: an object of fun and usefulness

Spy pen: an object of fun and usefulness
What more can be done to make a normal pen become extra ordinary? The question can be answered by the phrase "spy pen."  What is a spy pen? A spy pen is a gadget with capability of digital camera, video-audio recorder, music player, and FM radio. All of this technology is compress in a pen unit or placed in a pen like casing. It is truly impressive and amazing.
