Innehållsförteckning för #139 från Raspberry Pi Official Magazine

Raspberry Pi puts you at the forefront of computer experimentation. It's an exciting place to be, albeit a tad precocious. That's why our Troubleshooting feature (page 42) is such a vital read. It's packed with information on how to overcome any snags you might encounter. Not only will this make your Raspberry Pi experience more enjoyable, but you'll also become a better computer expert. This month sees the welcome return of #MonthOfMaking (page 68), where we all get together to show off the big builds we've been working on. We've also got two cases that support the new PCIe drives: NVME Base (page 76) and Argon ONE V3 M.2 (page 78). Both will vastly speed up your Raspberry Pi 5. Whatever you make with Raspberry Pi, be sure to share…

MAKER B-AROL-O Team The talented international team consists of Gianluca Tetri, Gianpaolo Macario, Pietro d'Agostino, Davide Macario, Andrea Podo and Orso Eric magpi.cc/freisa Real dogs tend to be fluffy and cute. Robodogs rather less so. But when you meet FREISA, a robotic dog created for a recent competition, you'll still want to give it a pat on the back and heap it with praise. For, just like its living, breathing canine counterparts, this impressive little thing is intelligent and skilled. It's capable of spotting a thirsty plant and making sure it gets enough water. FREISA – an acronym for Four-legged Robot Ensuring Intelligent Sprinkler Automation – is the brainchild of the B-AROL-O Team. This group won the popular vote of the OpenCV Spatial AI Contest in 2022 by creating a…

MAKER Pegor Karoglanian An embedded software engineer who likes to take on a variety of projects in his downtime. His goal is to get others excited to make something. github.com/PegorK Warning! Build & Climb Safely If you plan to recreate this project, it should only be attempted by people well versed in building (and climbing safety) magpi.cc/powertools During the various lockdowns at the start of COVID, people picked up various hobbies. Baking sourdough bread, setting up a new island in Animal Crossing, and getting some home exercise. Instead of deadlifts and HIIT, however, one maker helped a friend out with a special piece of equipment. “[It's] called the PeggyBoard,” Pegor Karoglanian tells us about his creation. “It's an interactive climbing wall powered by a Raspberry Pi that allows the user…

MAKER Dean Woodyatt Dean Woodyatt hails from Wales but now lives near Sydney. Having studied electronics, he describes himself as a tinkerer and a hoarder of any old tech. magpi.cc/thea500 Fans of Commodore's Amiga range of computers were overjoyed when a miniature version of one of the machines was released in April 2022. THEA500 Mini, as it's called, is a plug-and-play reimagining of the Amiga 500 but, while it's capable of playing thousands of games and comes with a mouse and joypad, there's a little problem with the keyboard. It doesn't work. Try as you might, you'll never be able to bash those keys because they're a solid, non-moving, unconnected block of plastic. That, however, hasn't prevented one Amiga enthusiast from dreaming of an alternate reality. Rather than plug in…

MAKER PJ Evans PJ is a writer, software engineer and tinkerer. His Play:1 now plays endless Rick Astley. mastodon.social/@mrpjevans Danger! High voltage. Many Sonos products have direct mains input which means residual charge can be present on the circuit board. magpi.cc/dischargecap Upcycling and the right to repair are hot topics right now. Just because an electronic device has failed, or is no longer required, it shouldn't mean instant landfill. When we came across a sad Sonos Play:1 that was more of a ‘Silence:1', we decided to investigate the possibility of repurposing the high-quality speaker and enclosure. The result was a new lease of life with plenty of options within its capabilities. This tutorial shows how to do it and is not just for a Play:1, but more of an example…

Even if you don't know the term for them, you very likely have seen a Rube Goldberg machine in cartoons, movies, or splashy adverts. They refer to elaborate, automated machines that perform a task – usually a simple one – with over the top chain-reaction mechanisms. Think a candle burning through a piece of string that releases a hammer to strike a ball into a tube that deposits the ball on a pulley system to lift up a blind. They're named after an American cartoonist, famous for the weird and wonderful contraptions in his comics, though British cartoonist W Heath Robinson did the same thing earlier. In an era before everything was part of the Internet of Things, weird gizmos that could turn on a light remotely or put your…

AUTHOR Mustafa Suleyman Price: £25 / $33 magpi.cc/comingwave The Coming Wave Artificial intelligence is the current buzzword thanks to the recent arrival of impressive online tools such as ChatGPT, Google Gemini and Meta Llama. You may well have played with these chatbots, but AI can do a lot more and has the potential to change all of our lives – for good or bad. This brave new world is explored in The Coming Wave by Suleyman, the co-founder of the DeepMind AI company (now part of Google). On the one hand, he argues, AI has great potential to diagnose diseases and discover new drugs. It could also transform agriculture, solve the climate crisis, and lead to greater prosperity. On the downside, AI may also be used for nefarious purposes to…

RAM check How do you check the RAM size of a Raspberry Pi, and what were the RAM variations released for Raspberry Pi 3 Model B+? Mahender via email You're in luck, for Raspberry Pi 3B+ only the 1GB version was released. Multiple RAM types started with Raspberry Pi 4, however there are also a couple of variations on original Model B hardware. On Raspberry Pi 5 it will say on the board how much RAM it has (there's a little resistor soldered next to the number) and on other Raspberry Pi boards you can check by opening the terminal and using: This will give you a revision code, which you can check against this list: magpi.cc/revcodes Image captions We really enjoy our MagPi subscription - thanks for all the…

01 FREISA utilises its camera and a machine learning algorithm trained using Roboflow (roboflow.com) to tell the robot's navigation system where the plants are located. It will analyse the state of the leaves and work out which plants require watering. 02 If it identifies dried-up plants, the robot will then ready itself. It will use its legs to get into position so that the robot's pelvic-located 3D-printed water sprinkling system (which includes a reservoir) is able to best target the thirsty plant. 03 At this stage, the sprinkling system bursts into action thanks to servomotors and a syringe that is able to draw up 10ml of water. The water is then dispensed on to the plant, and this is confirmed to the plant's owner, keeping a log of the event.…

MAKER Ambrogio Galbusera Ambrogio is a keen paraglider and “a true enthusiast who finds joy in the blend of technology, creativity, and the exhilarating freedom of the skies” magpi.cc/ambrogio There's plenty of interest in the 1980s: from Ghostbusters, The Goonies, to Back to the Future; whether riffing on cultural references and storylines a la Stranger Things or recreating props and costumes for cosplay and Halloween. In fact, so prevalent are such remakes that creator Ambrogio Galbusera named his Marty McFly and Doc Brown prop YAFC (yet another flux capacitor): magpi.cc/yafc. Ambrogio was keen to create a replica of the iconic flux capacitor that appeared in the Back to the Future film series and which Doc Brown reveals to Marty “is what makes time travel possible”. However, he wanted to design…

MAKER Gavin Chang An engineer at WIZnet who likes IoT and using it to solve problems in life. magpi.cc/gavinchang Be careful when using laser pointers in your projects and don't aim a laser pointer at a person's head. magpi.cc/lasersafety There are many ways to 3D scan objects, all of which seem to have been done with Raspberry Pi at some point. They're usually done to create 3D scans, however WIZnet engineer Gavin Chang is doing something a little different with laser scanning. “I wanted to make a radar application based on a two-degrees of freedom laser module,” Gavin tells us. “Through the actions of two servos, the laser module can scan in 3D to form distance information of all points in a space. This can be rendered through an algorithm…

MAKER Alasdair Allan Alasdair Allan is a scientist, author, hacker, and journalist. In the past, he has mesh-networked the Moscone Center, caused a US Senate hearing, and contributed to the detection of what was – at the time – the most distant object yet discovered in the universe. magpi.cc/docs Top Tip Update first At the time of writing, to get touch support on the 7-inch Touch Display you will need to use rpi-update to get a newer kernel. The CSI and DSI ports found on previous models of Raspberry Pi have been combined into two dual-purpose CSI/DSI (MIPI) ports on Raspberry Pi 5. These now use a denser connector pinout, previously only found on Raspberry Pi Zero and the CM4IO board. You can connect two displays, two cameras, or one…

INTERVIEW > Name Tim Stenning | > Occupation Shop Floor Manager > Community role Customer help | > URL raspberrypi.com The Raspberry Pi Store in Cambridge's Grand Arcade recently celebrated being open for five years – quite a feat for a store that started off life as a popup. One of the keys to its success was bringing in experienced electronics retail staff from the recently defunct Maplin, including Tim Stenning. “Not too long after Maplin closed I was approached by my manager [Oli Wilkin], who I had helped with the closing of the stores in Cambridge,” Tim tells us. “Remembering not having the chance to look at Raspberry Pi at Maplin, and [it] being a tech-centred experience, I took the opportunity and joined the team. Now, just over five…

THE FINAL WORD D id you notice a difference in the magazine this month? We've made a big change in how we make The MagPi as of this issue, as we had the incredibly talented art and design team at Raspberry Pi put together the mag. They've been doing the cover for us for a while now (it's a very important and involved step in magazine production) and I'm really happy with how this issue is turning out thanks to the efforts of Sara, Nat, Jack, and Brian! These are the folks that put together all the packaging and printed materials you see with official Raspberry Pi products, which I always think is fantastic. To have that expertise here on the magazine makes me think we come off as just that…

MAKER Ivan Kuleshov Ivan loves taking apart different devices to improve them, or learn how they work, and can't resist a hardware challenge. magpi.cc/uptimelab Self-confessed “hardware hacker” Ivan Kuleshov really likes making things. He's adept at using tools covering everything from microscopes to lathes, builds and flies drones and has won three separate hackathons. As long as he can remember, he's been beavering away on various projects related to hardware, from PC modding to the creation of homemade devices, racking up more than nine years on 3D printing and modelling. This aspect briefly became a business venture, but his day job is as a systems engineer in Munich with a string of certifications. His computing, coding and design skills also came in handy for his Mac Mini KVMac16 project, for…

MAKER Arnov Sharma Arnov is a microcontroller enthusiast and a maker from India. magpi.cc/arnovsharmer SNES XL is a gigantic Super Nintendo controller built by Arnov Sharma.

Button management Every button on SNES XL controller has its own custom PCB, created using PCBWay (pcbway.com) an online service for producing PCB prototypes. Each board is shown fully working by Arnov on YouTube (magpi.cc/snesxlyt). Tactile switches on the custom boards are positioned just below the 3D-printed buttons, such that pressing a button toggles its switch. Each of the switches is wired up to a pin on a XIAO SAMD21 (magpi.cc/samd21) development board from Seeed Studio (see Figure 1). When…

With a new model of Raspberry Pi comes change. The advancement of this little computer's amazing capabilities bring necessary changes to its operating system and in turn compatibility with older (and sometimes current) software and hardware. Since our original troubleshooting guide (The MagPi issue #60: magpi.cc/60), there's a lot that has changed and it's only right that we revisit the guide and bring it up to date for the newest member of the family: Raspberry Pi 5. So, if you're confused, perplexed or downright frustrated with a Raspberry Pi project, maybe some words of wisdom (or at least a clue) can be found in these pages. My Raspberry Pi will not power on! Raspberry Pi gone a bit nihilist? No life to be found? It can be more than a…
