Sometimes, gadgetry doesn’t have to be cool or sexy – or expensive – to be must-haves. ARTHUR GOLDSTUCK chooses the most practical new gadgets he tried out in 2015.
The most useful or practical gadgets are not the ones that will grace the covers of magazines or compete for product placement slots in movies. They tend to skulk unobtrusively in the background, or enhance high profile devices like laptops, tablets and even action cameras.
Some have been around, as product categories, in various formats for years. However, they are coming into their own via improved technology or design or both. For example, I had little faith in range extenders due to dismal performance delivered in the past. So dramatic was the performance delivered by a new variation on the theme, however, it leapfrogged the rest to hit number one on the list.
1. TrendNet N300 High Power Wireless N Range Extender (TEW-737HRE)
A regular frustration of home or office Wi-Fi is the dramatic drop-off in signal strength once the user is on the opposite end of the building from the access point, or even a few rooms away. A range extender works on a simple principle: it looks like a regular adaptor plug that fits into a regular power socket, and synchronises with the WiFi router to extend its signal, often to double the original range.
The TrendNet version is similar to many alternatives, including options from Asus and Linksys. But, as its name suggests, it packs high power into a small package. No installation is needed, and a single button is used to synchronise via a sync button found on most WiFi routers. While it may bother the securrty conscious by automatically adopting the router’s password and encryption, it also supports advanced wireless encryption for data protection.
As pervasive connectivity becomes an ever-greater need, range extenders like the TrendNet device will become common household accessories.

2. ErgoProp laptop stand
The laptop computer remains the preferred working tool for serious computer users, offering more productivity options and versatility than a tablet. The downside is that these very benefits result in the user typically being hunched over the device when hard at work. This invariably results in neck and shoulder pain, and even repetitive stress injury (RSI).
The Ergoprop is a deceptively simple approach to addressing this problem, allowing a laptop to be propped up to a more comfortable angle – and keeping it cooler by allowing air to pass under. It has a foldable foot so that it can be slipped into a laptop bag – although requiring slightly larger than average bags – to be available on the road as well.

3. Brydgeair Keyboard
This aluminium keyboard for the iPad Air and Air 2 is not unique and it’s not cheap, but it pairs better with an iPad Air than any other Bluetooth keyboard I’ve tried. It transforms an iPad into something very close to a small MacBook Air, with synchronisation options so seamless, it has the feel of being made by th4 same company.
Brydge is an independent iPad accessory company that started as a Kickstarter crowdfunding project and, like the company at which its accessories are aimed, is focused on design excellence. It should come as no surprise, then, that the keyboard integrates superbly with the iPad, both visually and technically.
It offers passable built-in speakers, backlit keys as on the MacBook Air, a 180 degree hinge for flexible viewing angles, and up to 3 months of battery life.

4. Gatekeeper Wireless Computer Lock & Tracker
Another low-cost gadget from a start-up, the Gatekeeper comprises a tiny USB jack that makes up the lock, and a small metal fob that acts as a remote key. The key links to the computer via Bluetooth, automatically locks the computer as the user moves away from it, and unlocks it or signs in when the user returns. The lock distance can be set for user preferences, although the setting is not very accurate, with a scale from “near” to “far”.
It’s not exactly plug and play, as it requires software to be downloaded and set up before its ready to run – or let you run.
It doubles as a location tracker, helping to locate devices and allowing users to set an alarm when a device is out of range. However, it’s ultimate benefit is as a security and privacy protector for computers used in workplaces, student study areas and other areas where unwanted access may occur as the user steps away from the computer.

5. World Panel SunStream
Portable power banks have become essential accessories for smartphone users in South Africa, as they find diminishing battery life not often balanced by access to charging points. But these, too, depend on plug points to get the power into the bank in the first place.
WorldPanel CEO John Anderson started off providing solar power for homes in Africa, but quickly realised there was as much of a need for solar smartphone chargers. The result is the SunStream, which converts sunlight into electricity that is streamed directly into the phone.
It is claimed to charge phones at the same speed as a wall plug, but does not provide quite the same consistency of throughput. Nevertheless, if one can “simply point the handheld panel toward the sun and plug in a device to stream electricity”, as the package states, it plugs a gaping hole in the handset ecosystem in Africa.
An optional PowerStream 3000 mAh power bank allows solar power to be converted into stored energy for later use – and is enough to provide a full charge for most smartphones.

6. RED-E 4000mAh PowerBank & BikeBar Mount Combo
This one is a little more specialised, aimed at keen bikers, particularly those who record their antics with GoPro and other action cameras. The downside of most of these cameras is limited battery power, sometimes offering as little as half an hour of recording.
The Red-E 4000mAh PowerBank and BikeBar Mount Combo attaches securely both to the bike’s handlebars and to the GoPro camera. The benefit of the dedicated secure connection is that vibration is minimised, but the overwhelming plus is the hours of extra recording time it offers, at a price that won’t stress the wallet.
The battery can be bought separately – meaning spares can be carried on a long trip – and delivers the established quality of RED-E power banks to action users.

Prepare your cam to capture the Blood Moon
On 27 July 2018, South Africans can witness a total lunar eclipse, as the earth’s shadow completely covers the moon.
Also known as a blood or red moon, a total lunar eclipse is the most dramatic of all lunar eclipses and presents an exciting photographic opportunity for any aspiring photographer or would-be astronomers.
“A lunar eclipse is a rare cosmic sight. For centuries these events have inspired wonder, interest and sometimes fear amongst observers. Of course, if you are lucky to be around when one occurs, you would want to capture it all on camera,” says Dana Eitzen, Corporate and Marketing Communications Executive at Canon South Africa.
Canon ambassador and acclaimed landscape photographer David Noton has provided his top tips to keep in mind when photographing this occasion. In South Africa, the eclipse will be visible from about 19h14 on Friday, 27 July until 01h28 on the Saturday morning. The lunar eclipse will see the light from the sun blocked by the earth as it passes in front of the moon. The moon will turn red because of an effect known as Rayleigh Scattering, where bands of green and violet light become filtered through the atmosphere.
A partial eclipse will begin at 20h24 when the moon will start to turn red. The total eclipse begins at about 21h30 when the moon is completely red. The eclipse reaches its maximum at 22h21 when the moon is closest to the centre of the shadow.
David Noton advises:
- Download the right apps to be in-the-know
The sun’s position in the sky at any given time of day varies massively with latitude and season. That is not the case with the moon as its passage through the heavens is governed by its complex elliptical orbit of the earth. That orbit results in monthly, rather than seasonal variations, as the moon moves through its lunar cycle. The result is big differences in the timing of its appearance and its trajectory through the sky. Luckily, we no longer need to rely on weight tables to consult the behaviour of the moon, we can simply download an app on to our phone. The Photographer’s Ephemeris is useful for giving moonrise and moonset times, bearings and phases; while the Photopills app gives comprehensive information on the position of the moon in our sky. Armed with these two apps, I’m planning to shoot the Blood Moon rising in Dorset, England. I’m aiming to capture the moon within the first fifteen minutes of moonrise so I can catch it low in the sky and juxtapose it against an object on the horizon line for scale – this could be as simple as a tree on a hill.
- Invest in a lens with optimal zoom
On the 27th July, one of the key challenges we’ll face is shooting the moon large in the frame so we can see every crater on the asteroid pockmarked surface. It’s a task normally reserved for astronomers with super powerful telescopes, but if you’ve got a long telephoto lens on a full frame DSLR with around 600 mm of focal length, it can be done, depending on the composition. I will be using the Canon EOS 5D Mark IV with an EF 200-400mm f/4L IS USM Ext. 1.4 x lens.
- Use a tripod to capture the intimate details
As you frame up your shot, one thing will become immediately apparent; lunar tracking is incredibly challenging as the moon moves through the sky surprisingly quickly. As you’ll be using a long lens for this shoot, it’s important to invest in a sturdy tripod to help capture the best possible image. Although it will be tempting to take the shot by hand, it’s important to remember that your subject is over 384,000km away from you and even with a high shutter speed, the slightest of movements will become exaggerated.
- Integrate the moon into your landscape
Whilst images of the moon large in the frame can be beautifully detailed, they are essentially astronomical in their appeal. Personally, I’m far more drawn to using the lunar allure as an element in my landscapes, or using the moonlight as a light source. The latter is difficult, as the amount of light the moon reflects is tiny, whilst the lunar surface is so bright by comparison. Up to now, night photography meant long, long exposures but with cameras such as the Canon EOS-1D X Mark II and the Canon EOS 5D Mark IV now capable of astonishing low light performance, a whole new nocturnal world of opportunities has been opened to photographers.
- Master the shutter speed for your subject
The most evocative and genuine use of the moon in landscape portraits results from situations when the light on the moon balances with the twilight in the surrounding sky. Such images have a subtle appeal, mood and believability. By definition, any scene incorporating a medium or wide-angle view is going to render the moon as a tiny pin prick of light, but its presence will still be felt. Our eyes naturally gravitate to it, however insignificant it may seem. Of course, the issue of shutter speed is always there; too slow an exposure and all we’ll see is an unsightly lunar streak, even with a wide-angle lens.
On a clear night, mastering the shutter speed of your camera is integral to capturing the moon – exposing at 1/250 sec @ f8 ISO 100 (depending on focal length) is what you’ll need to stop the motion from blurring and if you are to get the technique right, with the high quality of cameras such as the Canon EOS 5DS R, you might even be able to see the twelve cameras that were left up there by NASA in the 60’s!
How Africa can embrace AI
Currently, no African country is among the top 10 countries expected to benefit most from AI and automation. But, the continent has the potential to catch up with the rest of world if we act fast, says ZOAIB HOOSEN, Microsoft Managing Director.
To play catch up, we must take advantage of our best and most powerful resource – our human capital. According to a report by the World Economic Forum (WEF), more than 60 percent of the population in sub-Saharan Africa is under the age of 25.
These are the people who are poised to create a future where humans and AI can work together for the good of society. In fact, the most recent WEF Global Shapers survey found that almost 80 percent of youth believe technology like AI is creating jobs rather than destroying them.
Staying ahead of the trends to stay employed
AI developments are expected to impact existing jobs, as AI can replicate certain activities at greater speed and scale. In some areas, AI could learn faster than humans, if not yet as deeply.
According to Gartner, while AI will improve the productivity of many jobs and create millions more new positions, it could impact many others. The simpler and less creative the job, the earlier, a bot for example, could replace it.
It’s important to stay ahead of the trends and find opportunities to expand our knowledge and skills while learning how to work more closely and symbiotically with technology.
Another global study by Accenture, found that the adoption of AI will create several new job categories requiring important and yet surprising skills. These include trainers, who are tasked with teaching AI systems how to perform; explainers, who bridge the gap between technologist and business leader; and sustainers, who ensure that AI systems are operating as designed.
It’s clear that successfully integrating human intelligence with AI, so they co-exist in a two-way learning relationship, will become more critical than ever.
Combining STEM with the arts
Young people have a leg up on those already in the working world because they can easily develop the necessary skills for these new roles. It’s therefore essential that our education system constantly evolves to equip youth with the right skills and way of thinking to be successful in jobs that may not even exist yet.
As the division of tasks between man and machine changes, we must re-evaluate the type of knowledge and skills imparted to future generations.
For example, technical skills will be required to design and implement AI systems, but interpersonal skills, creativity and emotional intelligence will also become crucial in giving humans an advantage over machines.
“At one level, AI will require that even more people specialise in digital skills and data science. But skilling-up for an AI-powered world involves more than science, technology, engineering and math. As computers behave more like humans, the social sciences and humanities will become even more important. Languages, art, history, economics, ethics, philosophy, psychology and human development courses can teach critical, philosophical and ethics-based skills that will be instrumental in the development and management of AI solutions.” This is according to Microsoft president, Brad Smith, and EVP of AI and research, Harry Shum, who recently authored the book “The Future Computed”, which primarily deals with AI and its role in society.
Interestingly, institutions like Stanford University are already implementing this forward-thinking approach. The university offers a programme called CS+X, which integrates its computer science degree with humanities degrees, resulting in a Bachelor of Arts and Science qualification.
Revisiting laws and regulation
For this type of evolution to happen, the onus is on policy makers to revisit current laws and even bring in new regulations. Policy makers need to identify the groups most at risk of losing their jobs and create strategies to reintegrate them into the economy.
Simultaneously, though AI could be hugely beneficial in areas such as curbing poor access to healthcare and improving diagnoses for example, physicians may avoid using this technology for fear of malpractice. To avoid this, we need regulation that closes the gap between the pace of technological change and that of regulatory response. It will also become essential to develop a code of ethics for this new ecosystem.
Preparing for the future
With the recent convergence of a transformative set of technologies, economies are entering a period in which AI has the potential overcome physical limitations and open up new sources of value and growth.
To avoid missing out on this opportunity, policy makers and business leaders must prepare for, and work toward, a future with AI. We must do so not with the idea that AI is simply another productivity enhancer. Rather, we must see AI as the tool that can transform our thinking about how growth is created.
It comes down to a choice of our people and economies being part of the technological disruption, or being left behind.
