In the recent decade, Virtual Reality (VR) has become more common through a range of systems including computer-powered head-mounted displays (HMDs) and smartphone-powered headsets. It has presented both designers and developers alike with a new field filled with unexplored potential. In this article, a new and inexpensive approach to VR is explored, allowing entry-level smartphones to run powerful computer-based VR experiences wirelessly through Bluetooth with relative high levels of performance. The project was recognised as a European and African Finalist in the Google Science Fair 2015.
There are many parts of the modern world that seem to run on a strange type of magic – a sorcery based on doped silicates and rare earth metals. With a little attention, this magic looses it’s sheen and the sufficiently advanced technology behind it is revealed. In this article I will cover how some of the most fundamental parts of modern computing can be demystified.
Multiple webcams were streamed live via the use of a Raspberry Pi, a credit card sized computer. Four webcams attached to the Pi was not possible which may be due to the Pi having an insufficient number of CPUs, however, three webcams was possible and were streamed live via the local network. The latter has applications in research where one needs to view different parts of an experiment at the same time, including different parts of a laser beam in order to check for alignment.
