Animal Soundscapes: Monitoring Biodiversity In The Jungle
Tropical forests are noisy places, the air filled with the sounds of a wide diversity of birds and animals. They are also rather physically taxing thanks to daily thunderstorms, intense midday heat, and mountainous terrain. It makes it difficult for ecologists to perform manual field studies, which are thus prone to a high failure rate. So research postgraduate Sarab Sethi – along with his supervisors Prof Rob Ewers, Dr Nick Jones, and Dr Lorenzo Picanali – have devised a real-time ecosystem monitoring device based around a Raspberry Pi. “Our particular interest was in recording audio to capture the soundscape – or the combination of all the vocalising animals – as this is a rich data source that can be used to track birds, mammals, frogs, and more,” Sarab tells us. For this, the scientists required a device that could continuously record, compress, and upload huge amounts of data from the field while exploiting a patchy mobile signal to remotely transfer data to a server. “The Raspberry Pi was ideal as a low-cost, relatively low-power device with a usable amount of computing power and large support for a wide range of sensors,” says Sarab. This is the view from underneath the solar panel, with everything firmly strapped or taped into place Jungle sounds With their field site in Sabah, Borneo, in mind, they set about creating a system that could monitor the effects of oil palm plantations and logging on the region’s biodiversity by listening out for the sounds of animals. It involved using a Røde smartLav+ microphone to provide high-quality audio recordings, along with an external USB audio card, solar energy, and a 3G dongle to connect to the internet. The ultimate aim is to use artificial intelligence to pick up on the audio and make sense of the data. For now, however, the Python-programmed software runs two threads concurrently: one continuously records data from a sensor and stores it in uncompressed files, and the second compresses this data and robustly uploads it using FTP to a remote server. “It is important that the device is networked to minimise the amount of times a scientist or research assistant has to go to visit the device to manually collect the data – freeing up time to be better spent on other more efficient and less exhausting tasks,” explains Sarab. “Large animals also love to play with (or more likely destroy) any…

Model Lighthouse built with Raspberry Pi
When Dave knew that he would be getting married in a unique London lighthouse, he decided to make some very original wedding table centrepieces: working models of the Trinity Buoy Wharf Lighthouse in which the nuptials were taking place. Not only that, but he resolved to make ten of them – quite an undertaking. As Dave explains, “With my love of 3D printing, Raspberry Pis, and needlessly complicated projects, recreating the lighthouse as a working model seemed like the way to go.” Trinity Buoy Lighthouse Model: quick facts Trinity Buoy Wharf is the site of London’s only lighthouse The lighthouse model was designed in Autodesk 123D Dave used his Prusa MK2.5 to 3D-print components A jam-jar is used for the glass light casing Dave gave most of the models to wedding guests – one is now in Australia Trinity BuoyLighthouse Buoy oh buoy! Over a three- to four-month period, before his August 2018 wedding, Dave designed, 3D-printed, and completed the models with, unsurprisingly, “the last month being pretty non-stop.” A time-consuming project, modelling the lighthouse necessitated a lot of work, and Dave used many photographs of the real-life lighthouse to guide his progress. In addition, as he explains, “The software I used on the Pi was pretty simple, although I tweaked it a few times. The two most challenging parts were fitting in all the printing time, and the mechanism for the rotating light. I went through a couple of major versions of that, a lot of minor versions, and still never got it 100% reliable – turns out rotating and maintaining a circuit is quite hard!” The 3D printing time was indeed considerable, as each model required 44 hours of printing in order to produce the six key pieces: outer, inner, railing, cap, base, and base lid. In terms of function, the models include an 18650 battery (in a shield), a Raspberry Pi, and an LCD display in the base. At the top is a warm white LED light on top of a stepper motor. “Wires run up the middle and when you turn on the battery, it powers on the light and the Pi,” reveals Dave. “The Pi then starts turning the motor (and light) and displaying various messages on the display.” Concealed in the base are a Pi Zero, battery, motor board, and LCD; the wiring proved challenging Building a model lighthouse Understandably, the project was far…

Steam Link on Raspberry Pi
Steam Link Raspberry Pis have been something of a dream for many years. While there are DIY, hacky methods to make one, Valve has now released the Steam Link software directly for Raspberry Pi. Steam Link on Raspberry Pi is very important It’s currently in beta, and available right now as a package you can install in Raspbian. Valve recommends using a Raspberry Pi 3 or Raspberry Pi 3B+ for it, and early reports suggest it’s already working extremely well. Pi-based replacement? Gone, but not forgotten It’s interesting timing now that the original Steam Link hardware is being discontinued by Valve. Does it hint towards a software future for their streaming solution? Maybe even a Steam-branded Pi solution? We’ll definitely be keeping an eye on what they do. The post Steam Link on Raspberry Pi appeared first on The MagPi Magazine.

National Centre for Computing: Raspberry Pi in £78m education boost
Computing education in England is about to get a much-needed jolt of funding with the help of the Raspberry Pi Foundation. The money will found a new National Centre for Computing. The welcome computing cash injection comes a year after The Royal Society reported that there was a ‘once-in-a-generation opportunity’ to transform the way computing is taught in schools and colleges. Commenting on the report, Raspberry Pi Foundation CEO Philip Colligan noted that “there’s a long way to go before we can say that young people are consistently getting the computing education they need and deserve in UK schools.” See also: Coolest Projects comes to the UK Pi 3 makes ‘ultimate education list’ for engineers BBC Computer Literacy archive The best Python websites and resources A Royal Society report last November drew attention to the scale of the challenge in transforming the way we teach computer science in the UK Raspberry Pi helps secure £78m for STEM education The Raspberry Pi Foundation is one of the organisations that, jointly, have secured £78 million in UK government funding to make this vision a reality. The Foundation is part of a consortium that also includes STEM Learning and the BCS (British Computer Society). Google has also pledged £1 million to support free online computing and computer science courses accessible to anyone. While existing computing and ICT (information and communications technology) teachers are being directly targeted, the scheme will also upskill existing teachers in other disciplines to teach GCSE Computer Science. Philip explains that the money will be used “to make sure every child in every school in England has access to a world-leading computing education.” Teachers will get resources, training, research, and certification as part of the programme The consortium will found a new National Centre for Computing – with a network of computing hubs where existing primary and secondary school computing teachers in England will be able to take part in fully funded CPD (continuing professional development) courses. Teachers will also have access to free resources enabling them to teach computing to students from Key Stage 1 right up to A-Level. As part of an all-hands-on-deck approach to overhauling computing teaching in England, the Raspberry Pi Foundation and its consortium have more than 60 organisations signed up to offer practical assistance and expertise. Businesses, universities, and non-profit organisations are pooling their expertise and resources to provide the support that educators and schools require. You…
