I still remember unboxing my Raspberry Pi for the first time. My first encounter with this single-board computer was daunting to say the least. I got the keyboard, mouse, and operating system set up, but didn't get much further. It wasn't until six months later that I got around to building ‘Tyres’, my first beloved Raspberry Pi robot. He's still trundling around here somewhere. What made the difference was a good guide. And that's what we want Start Your Raspberry Pi Adventure (page 40) to be! This feature will walk you by the hand through setting up Raspberry Pi and starting out on a maker's journey. We hope you'll forgive PJ's puns, but isn't Sam's artwork lovely! Rob has also crafted a great Beginner-Friendly Projects guide (page 72). If anybody…

MAKER Dr Tom Wilkes is a lecturer in volcanology at the University of Sheffield, where he has used Raspberry Pi for several monitoring projects. volcanotech.org I celand is currently on standby for imminent eruptions, while Sicily's Mount Etna gave off stunning emissions in late summer. However, most volcanic activity takes place in lesser-known, less touristy and often poorer nations, where preparations for a big blowout are far harder to facilitate. Furthermore, their remote locations can make installing equipment to track seismic activity an expensive challenge. “UV cameras provide invaluable data for both monitoring and research,” explains University of Sheffield volcanologist Dr Thomas Wilkes, “but funding in volcanology, particularly for monitoring organisations, is often limited, prohibiting their widespread adoption.” For his PhD thesis, Tom set about designing low-cost ground-based remote sensing…

MAKER Lee is a technology enthusiast covering Raspberry Pi singleboard computer projects. magpi.cc/leepspvideo L ee, of the Leepspvideo YouTube channel, was having a whale of a time testing out Raspberry Pi 5 using the Dolphin emulator (dolphin-emu.org), as well as running his dualscreen setup (magpi.cc/dualscreensetup). So far, so impressed – but then his mind wandered and landed on the question: “Will a Raspberry Pi 5 fit inside SunFounder's RasPad 3?” RasPad 3 is a tablet designed around Raspberry Pi 4, which has an Ethernet port on the opposite side of the board to Raspberry Pi 5. There were also questions around whether RasPad 3 could power the more powerful Raspberry Pi 5. You can watch the ‘First Raspberry Pi 5 tablet’ build on YouTube (magpi.cc/5tabletYT). Tight fit The project began…

MAKER Csaba's extensive interests cover technical and artistic domains including programming, hardware development, 3D printing, photography, and filmmaking. github.com/CinePI Canadian creative maker Csaba Nagy spent hours during his university course immersed in the world of camera sensors and computer vision, nicely complementing his degree in computer science. Raspberry Pi's ability to connect with so many other devices, plus the possibilities of the camera module, piqued his interest. He subsequently developed CinePI – an open-source project that was “a direct result of the intersections between my passions for programming and filmmaking” – to add cinema camera features to Raspberry Pi. In early 2023 Csaba launched version 2, based around a Raspberry Pi 4 and 12.3 megapixel HQ Camera (magpi.cc/CinePI). Now he's back, with CinePI XL. Big ambitions Csaba says that CinePI…

MAKER Karl is a PhD student at Trinity Hall Cambridge. magpi.cc/piartframegit This excellently simple fractal art display (magpi.cc/piartframe) by Cambridge student Karl Mose is perfectly pitched as a beginner project for someone looking for a geeky desk trinket. What are fractals? Fractals are shapes that contain complex detail however closely you look at them, or however far you zoom in. Often, they are self-similar: if you zoom in on the small-scale detail, you find it resembles the overall shape. Some of the most familiar forms that have fractal features are ones found in nature, like fern leaves and frost patterns, and we bet we're not the only ones who call Romanesco “fractal cauliflowers”. They are also beautiful. Fractal art can be created algorithmically by software, with the results usually represented…

THE FINAL WORD I've definitely written before in this column about setting goals for a new year and what I had planned. Problem is, I'm very good at not always doing them. Yesteryear's goals become half of this year's goals – like perpetually saying at new year you'd go to the gym more, but based around hobby stuff. I've learned to live with it. On the one hand, stuff happens and life can be unpredictable. I might have had time to work on a script or a model one evening, but then a friend hits me up to hang out or a parent calls or I'm very sleepy and need a nap. Should probably work a bit on that last one, to be honest. I'm lucky that I get a…

MAKER Rob is a professional computer programmer, VR flight/space/ racing SIM enthusiast, amateur videographer and general lover of gadgets, including old ones. magpi.cc/robfisher Buying a used Amiga 1200 – a computer launched by Commodore in 1992 just two years before it filed for bankruptcy – is sure to leave a dent in your wallet. The 32-bit machine in its most basic form tends to sell for upwards of £300. Add a hard drive, memory expansion or an accelerator card and you may want to arrange a meeting with your bank manager. You may then need to splash out more replacing the capacitors which are prone to leaking, potentially causing damage to the circuit board.

Tanay is an undergrad student pursuing a bachelor's degree in Software Engineering. He's enthusiastic about hardware and software technologies. magpi.cc/verticalfarm MAKER Farmers always need lots of land, right? Well, not necessarily. There is a practice called vertical farming which involves cultivating crops in stacked, tower-like layers. When using this method, the environment is carefully monitored and controlled, lending factory-style precision to the process of growing plants. It has the potential to revolutionise food production, but it's also quite expensive. Recognising the costs involved, Raspberry Pi enthusiast Tanay has produced his own version. In creating a smart vertical farming system powered by a Raspberry Pi 4 computer, he's enabling plants to be monitored and precisely watered with minimal human intervention while taking into account numerous environmental factors to optimise their growth.…

MAKER Rusty started out with a solar-powered surfboard trying to autonomously head from LA to Hawaii and Blue Robotics grew to develop hundreds of low-cost marine components. bluerobotics.com BlueROV2 is an underwater ROV that surveys the darkest depths – well, the really very gloomy depths anyway – with the help of a Raspberry Pi 4 wearing its bespoke Navigator Flight Controller as a HAT. What is an underwater ROV? If you're not sure what an underwater ROV is, the short answer is: a Remotely Operated Vehicle you chuck in the sea. But if you're our favourite kind of geek and wish to feast on a much longer answer, Blue Robotics has shared a short history and explanation of how they work, including the excellent tidbit that the first ever ROV…

PROJECT SHOWCASE A visual artist, musician, and engineer whose art explores obsolescence, nostalgia and rebirth by deconstructing, enlarging and twisting the forms of early handheld gaming systems. connorg.ca MAKER There have been a discussions for decades now on whether or not video games can be considered art. The short answer in our minds is; yes, they can be. Unfortunately the longer answer isn't really relevant to this magazine, but what is relevant is three-foot-tall Game Boy (and other handheld) replicas powered by Raspberry Pi that are displayed as fine art themselves. “I had been working building large format fine art using canvases, paint, and paper and had just started exploring using Coroplast [corrugated plastic – Ed] to add a three-dimensional element to my work,” creator Connor Gottfried tells us. “I…

MAKER An engineer and electronics hobbyist who likes to experiment with the latest hardware and technologies, he also builds retro gadgets around 1980s tech. magpi.cc/fixgalaga When you get to your early 40s like 1981’s Galaga, you may find that everything doesn't quite work as well as it used to. Maker Nick Bild's mini Galaga arcade machine is significantly younger than the original cabinets, but still found itself in a position for repairs. They wouldn't be easy, so Nick came up with a very creative solution. “I came up with an elaborate way to ‘fix’ it involving robots, Raspberry Pis, computer vision, and more,” Nick tells us. “I first created a first-person view robot that streams data to a Raspberry Pi 4 that I put in the arcade cabinet. Using the…

Ben's house is slowly being taken over by 3D printers. He plans to solve this by printing an extension, once he gets enough printers. Most microcontroller programming environments have a way of making beeps, and even if there's not an in-built method, it's a pretty simple thing to do – just flick a pin on and off quickly (but not too quickly) and you have an audio signal that you can send to a speaker, headphones, or other audio devices. CircuitPython, however, has just gained a complex audio synthesis module called synthio. This lets you not just create beeps and boops, but control these sounds in a variety of ways. Let's take a look. You'll need a board that supports synthio. RP2040 boards, such as Pico and Pico W, are…

INTERVIEW > Name Allie Weber > Occupation Student, content creator > Community role Content creator > URL @RobotMakerGirl Allie Weber is 18, which means that she was about seven years old when Raspberry Pi came out.
