Aside from the adventure of the drive, an important focus of The 2015 African Solar Drive is to raise awareness and promote green technology.  By showcasing Ilanga II and hosting public lectures, the UJ Energy Movement aims to educate schools, researchers and people that are interested in pursuing a career in the fields of science and engineering, specifically relating to alternative energy.  The lectures will be taking place in Kimberley, Upington, Windhoek and Gaborone.

During the 4 160 km educational road trip, engineering students will also be collecting and analyzing data to optimise the performance of the vehicle.

Mechanical Engineering Science lecturer and the UJ Energy Movement Programme Manager, Nickey Janse van Rensburg says “The UJ Energy Movement programme was established in 2010 to help promote skills development, energy conservation and sustainability through technology innovation. We are really excited to be taking Ilanga II on its longest trip yet and introducing the programme to our neighbours across Africa.”

Spectators can look forward to seeing Ilanga II along the route and at specific pit stops; the solar powered electric car was awarded the Technology and Innovation Award at the 2014 Sasol Solar Challenge and is one of the most advanced solar powered vehicles produced by UJ students and industry partners to date.

Team and Technology Manger of the Energy Movement programme, Warren Hunter, explains that there are a lot of logistical arrangements behind The 2015 African Solar Drive. “A team of engineers and academics has been involved in the technical planning of this twelve day road trip to make sure operations run as smoothly as possible. We are also happy to announce that Mitsubishi is the official transport partner of the ground patrol team.”

Low-cost wireless sport earphones get a kickstart

Wireless earphone brands are common, but not crowdfunded brands. BRYAN TURNER takes the K Sport Wireless for a run.

Published

on

As wireless technology becomes better, Bluetooth earphones have become popular in the consumer market. KuaiFit aspires to make them even more accessible to more people through a cheaper, quality product, by selling the K Sport Wireless Earphones directly from its Kickstarter page

KuaiFit has an app by the same name which offers voice-guided personal training services in almost every type of exercise, from cardio to weight-lifting. A vast range of connectivity to third-party sensors is available, like heart rate sensors and GPS devices, which work well with guided coaching. 

The app starts off with selecting a fitness level: beginner, intermediate and advanced. Thereafter, one has the ability to connect with real personal trainers via a subscription to its paid service. The subscription comes free for 6 months with the earphones, and R30 per month thereafter. 

The box includes a manual, a USB to two USB Type B connectors, different sized soft plastic eartips and the two earphone units. Each earphone is wireless and connects to the other independently of wires. This puts the K Sport Wireless in the realm of the Apple Earpods in terms of connection style. 

The earphones are just over 2cm wide and 2cm high. The set is black with a light blue KuaiFit logo on the earphone’s button. 

The button functions as an on/off switch when long-pressed and a play/pause button when quick-pressed. The dual-button set-up is convenient in everyday use, allowing for playback control depending on which hand is free. Two connectivity modes are available, single earphone mode or dual earphone mode. The dual earphone mode intelligently connects the second earphone and syncs stereo audio a few seconds after powering on. 

In terms of connectivity, the earphones are Bluetooth 4.1 with a massive 10-meter range, provided there are no obstacles between the device and the earphones. While it’s not Bluetooth 5, it still falls into the Bluetooth Low Energy connection category, meaning that the smartphone’s battery won’t be drastically affected by a consistent connection to the earphones. The batteries within the earphones aren’t specifically listed but last anywhere between 3 and 6 hours, depending on the mode. 

Audio quality is surprisingly good for earphones at this price point. The headset style is restricted to in-ear due to its small design and probable usage in movement-intensive activities. As a result, one has to be very careful how one puts these earphones, in because bass has the potential of getting reduced from an incorrect in-ear placement. In-ear earphones are usually notorious for ear discomfort and suction pain after extended usage. These earphones are one of the very few in this price range that are comfortable and don’t cause discomfort. The good quality of the soft plastic ear tip is definitely a factor in the high level of comfort of the in-ear earphone experience.

Overall, the K Sport Wireless earphones are great considering the sound quality and the low price: US$30 on Kickstarter.

Taxify enters Google Maps

A recent update to Taxify now uses Google Maps which allows users to identify their drivers, find public transport and search for billing options.

Published

People planning their travel routes using Google Maps will now see a Taxify icon in the app, in addition to the familiar car, public transport, walking and billing options.

Taxify started operating in South Africa in 2016 and as of October 2018 operates in seven South African cities – Johannesburg, Ekurhuleni, Tshwane, Cape Town, Durban, Port Elizabeth and Polokwane.

Once riders have searched for their destination and asked the app for directions, Google Maps shares the proximity of cars on the Taxify platform, as well as an estimated fare for the trip.

If users see that taking the Taxify option is their best bet, they can simply tap on the ‘Open app’ icon, to complete the process of booking the ride. Customers without the app on their device will be prompted to install Taxify first.

This integration makes it possible for users to evaluate which of the private, public or e-hailing modes of transport are most time-efficient and cost-effective.

“This integration with Google Maps makes it so much easier for users to choose the best way to move around their city,” says Gareth Taylor, Taxify’s country manager for South Africa. “They’ll have quick comparisons between estimated arrival times for the different modes of transport, as well as fares they can expect to pay, which will help save both time and money,” he added.

Taxify rides in Google Maps are rolling out globally today and will be available in more than 15 countries, with South Africa being one of the first countries to benefit from this convenient service.
