Editor Lucy Hattersley Lucy is trying to coax a virtual environment with a swapfile to install a frankly ludicrously large model and is loving every minute of it. rpimag.co Artificial intelligence is at the heart of the modern tech industry. Through cyclical processes of training and inference, this remarkable technology helps us understand masses of data, make decisions much faster and at scale (if not necessarily better), and make our devices smarter and more intuitive. The engineers at Raspberry Pi have been busy helping our favourite computer get ready for this remarkable new generation of technology. Alongside a bulkier 16GB Raspberry Pi 5 model with extra RAM to contain larger AI models, we have custom accelerator hardware like AI HAT+ and Raspberry Pi AI Camera with Sony IMX500 Intelligent Vision…

Maker Théo, who goes by the internet names tzvc and Rootkid, has a master's degree in computer science and says he has been tinkering with machines since the age of mythology. rpimag.co/whisperwires When Théo Z V Champion visited a vintage market in London, he noticed that shoppers were rather intrigued by a rotary phone – the type that needed callers to choose a number by inserting their fingers into the relevant holes of a dial before turning the wheel in order to initiate a telephone call. It was disconnected, but that didn't prevent many people – acting out of curiosity or feeling pangs of nostalgia – from lifting the handset and placing it against one of their ears. In each case, they were met with silence. They'd place the handset…

Maker PJ is a writer, software engineer and tinkerer. Working at home for so long, he's learnt to open a window now and again. mastodon.social/@mrpjevans YOU'LL NEED • Badger 2040 W rpimag.co/badger2040w • SCD41 CO2 sensor rpimag.co/scd41 • LiPo Amigo rpimag.co/lipoamigo • 1200 mAh 3.7 V LiPo battery rpimag.co/1200lipo • 4-pin JST-SH cable (50 mm) rpimag.co/jstsh There's something in the air. Well actually: there's lots of things in the air, not just good old oxygen. We exhale carbon dioxide (CO2) and that means that in an enclosed space containing one or more people, the amount of CO2 can increase unless there's good ventilation. When CO2 goes over 1000 ppm (parts per million) in a room, it can start to have consequences for your clarity of mind. At 2000 your cognitive…

Maker Nicola is a freelance writer and sub-editor. Her load of flannel this month is very much intended to be used with some soap. @holtonhandmade We'll take a look at soap bar making, with an eye on 3D-printing your own soap mould too It's a daily necessity and common household substance that we all use in some form or another as, not only does soap cleanse, but it also sanitises and destroys bacteria. Following the Industrial Revolution, alongside a growing awareness of sound sanitary practices and advertising to encourage bathing with soap, soap bars became popular and mass production swiftly followed. Today, we don't think twice about buying bars of soap with our groceries, and may sometimes opt for slightly fancier soap bar versions (perhaps a certain French brand that this author…

Name Nicola King Occupation Freelance writer/sub-editor Community role Crafter and maker URL @holtonhandmade Nicola is a name you'll have seen grace the pages in the various publications by Raspberry Pi for a long time now, and currently she's our resident craft tutorial expert. Nicola covers everything from making paper to computer-programmed embroidery – and this month she's making soap with a tech twist. “My mum taught me to sew when I was maybe six or seven, and I remember handsewing dresses for my Sindy doll (that dates me!),” Nicola says. “I learnt to knit shortly after that, and it's just something that sticks with you, even if you don't knit anything for a while; it's like riding a bike. I taught myself crochet around ten years ago using YouTube, and…

On the bookshelf Is there a plan to update the Bookshelf app now that The MagPi is Raspberry Pi Official Magazine? Thanks in advance. Jack via the blog The Bookshelf app on Raspberry Pi OS was technically updated the moment the new issue with the new name was released! As the PDF doesn't appear on the app until three weeks after launch, it will take a little while for the changes to be apparent, though. Of course, if you'd like the PDF earlier, making a contribution on the RPOM website (rpimag.co) will grant you access to the PDFs from day one, and print subscribers also get day-one access to the PDFs. Link retention With the change to the magazine URL, I hope something has been put in place to make sure…

Maker Adam is an Apple software specialist who focuses on interaction design, animations, gestures, and reverse engineering. rpimag.co/mclarencarplay How to trick the car into thinking his Raspberry Pi was an iPhone In a scenario that is somewhat outside our own range of experience, software engineer and car enthusiast Adam Bell recently became the brand-new owner of a McLaren 720S. The car is resplendent in McLaren Orange and “amazing in every single way… except for the lack of CarPlay”, having launched (in 2017) just before the in-car entertainment system became prevalent. Despite being the very proud owner of a supercar (and sufficiently skilful to handle the corkscrew at Laguna Seca), Adam missed the way CarPlay automatically connects and streams audio wirelessly from his iPhone, especially as he drives the car on…

1. A database created using artistic works pulls narrated poems from the Poetry Foundation website. An AI model called WhisperX creates word-level accurate transcriptions of those poems and a large language model strips them of any intros and outros. 2. When someone picks up the handset, the phone will automatically and immediately pull a random poem from the database. It will begin to play the audio through the earpiece, complete with an authentic phone audio grain for added nostalgia. 3. When the poem is finished, the poet ‘hangs up’ and this leaves the listener with a disconnect tone. All the listener has to do is put the handset back on the phone's base and pick it up again. The phone will then pull another random poem from the database.…

Maker A software engineer by day who has been building open-source robots for five years, logging the build process as he goes. makerforge.tech A robot companion is a bit like a pet, but without the muss or fuss as a Tom & Jerry cartoon once put it. While this one stands on two legs, it currently cannot walk; for maker Dan Nicholson, however, that wasn't the point of his long ongoing project. “It includes an easy-to-learn, custom software framework that supports functionality like object and face detection, animation, voice recognition, text-to-speech, AI integration, and much more,” Dan explains. “I've focused heavily on documentation, and made design choices to keep the project accessible to as many people as possible. The goal is to make an autonomous desktop buddy that others can…

rpimag.co/FA18C To many readers, ‘F/A-18C Right Console’ will look like a bunch of letters and numbers thrown together. To aviation enthusiasts, though, those letters and numbers clearly refer to the McDonnell Douglas F/A-18 Hornet, a fighter plane developed in the 1970s for the US Marines and US Navy. This replica control console by ValeNoxBona was apparently the maker's first ever build using the Arduino microcontroller, which is used to control the addressable RGB LEDs that light this project. The build uses a 3D-printed enclosure with a laser-cut and engraved acrylic top, backlit with WS2812 addressable RGB LEDs mounted on a custom PCB and controlled by the Arduino. The lettering is engraved into the acrylic, which makes the material thin enough for the lights underneath to shine through. Apart from the…

Maker K.G. is a writer, game developer and musician who not only owns a CRT TV, but has to be actively prevented from buying more when they visit charity shops. twoot.space/@owlbear Retro games just don't look the same on modern LCDs. Computer game pixel art of the 1980s and 1990s was designed to benefit from the fuzzy edges, bleeding colours and low resolutions of PAL, NTSC and SECAM CRT TVs and monitors. The phosphor dots that make up a CRT TV's pixel grid appear rounded, as compared to the hard edges of pixels displayed on LCD and OLED monitors. Artwork that takes advantage of every limitation of the system and screen Casting shade Computer game artists were familiar with these limitations and took advantage of them to create pixel art…

I'm looking at a Raspberry Pi 500 on my desk. In many ways it's a throwback: like a time machine disguised as a keyboard. It could become my holy trinity of childhood computing: Spectrum, Commodore 64, or the Amiga 500 with which it shares its name. I've turned it into all three at one point. The design isn't nostalgic, though: it's purposeful. Placing the ultra-powerful Raspberry Pi inside a keyboard produces a modern computer that's supremely hackable. It can be anything I want. A modern Linux desktop, a coding powerhouse, and a platform to experiment with the cutting edge of electronics and software. Sony's use of Raspberry Pi AI Camera on its production line proves this isn't just nostalgic tinkering Raspberry Pi isn't – for me – a nostalgia engine.…

Makers Finland-based software engineers Michael and Marcos regard firmware as their bread and butter. inputlabs.io Software engineers Michael Przybilski and Marcos Diaz set up Input Labs in late 2022 with a mission of enabling “people with disabilities such as arthritis, who have difficulties holding and operating traditional pointing devices, such as computer mice, to comfortably work with computers”. Now based at the renowned Maria 01 startup campus near Helsinki, Input Labs’ founders are passionate about open-source hardware and the mutually supportive communities that help drive innovation and improvements. A year into their journey, Marcos and Michael announced a 3D-printable version of a traditional gaming controller that “enables the user to aim comfortably, with two hands, while making the interaction with the computer very precise”.

Maker Finnley became an avid electronics fan and maker thanks to his Dad's interest in Heathkits and through TV shows such as The Secret Life of Machines. rpimag.co/rpiclock Television has a lot to answer for! Mr Wizard was one of the earliest TV science shows, debuting in the US in 1951 and running until 1965. The programmes comprised practical demonstrations to children using everyday objects. Presenter and educator Don Herbert (whose Mr Wizard shows can still be seen at mrwizardstudios.com) caught the imagination of children such as Finnley Dolfin. The maker credits the show and the influence of his electronics-mad father for sparking his own lifelong interest in how things worked. The Raspberry Pi Zero W-based Voltmeter Clock Boxes combine Finnley's interest in old electronics with modern components. Sparking an interest…

Maker Jaeheon is a computer science student currently studying for his bachelor's degree at Georgia Tech. In his free time, he likes to make cool projects, both on the computer and in the real world! rpimag.co/inkydashboard If you've got a busy schedule, then it's all too easy to become overwhelmed. Without a good system in place, you'll find deadlines slip, appointments are missed, and you're constantly playing catch-up. It's why there are so many calendar and task management apps on the market and, crucially, why Jaeheon Shim decided to take his scheduling to another level. “As a student, staying organised is crucial for keeping up with the demands of college life,” he says. “I found myself relying on productivity apps like Google Calendar, Todoist, and Notion, but they weren't enough.…

Artificial intelligence is the buzziest of tech topics. And (for better or worse) this is the year that it is seriously being deployed into the world. Ready or not, businesses and governments are swapping out workers for trained models, artists are pushing back against generative adversarial networks trained on their work, and writers are pushing back against generative pre-trained transformers. Meanwhile, autonomous car-driving technology is rapidly going through approval processes in various territories. We live in interesting times. But you never know what the future will bring, so let's not get bogged down with worry. All this stuff is fascinating to learn, and the mental reward is huge. It's great to know how this stuff works. This month we built an AI technology stack using Raspberry Pi technology. Raspberry Pi…

Maker With a house and shed full of lathes, milling machines, 3D printers, and more, Jo is a constant tinkerer and is passionate about making. Obsessed with rockets and robots and much more besides, he often releases designs and projects as open source. concretedog.blogspot.com We've looked at the Meshtastic project before, back in HackSpace issue 80 (rpimag.co/hs80), which is a great read that you should definitely check out if you are unfamiliar with Meshtastic: it would serve as a great introduction for these articles. As a brief introduction, Meshtastic is an open-source project that uses affordable LoRa-equipped hardware to create off-grid communications networks (Figure 1). Beyond that, it's a capable and fun platform for experimenting with different hardware and antennas and other technical areas. In the first part of this…

Maker Andrew is a specialist fabricator and maker, and is the owner of the Andrew Lewis Workshop. lewis-workshop.com Warning! Fire Flame polishing should take place in a controlled environment, away from children, pets, and other flammable materials rpimag.co/fire Life is very seldom as precise or fair as we would like it to be. This is particularly true when we're machining or 3D-printing parts. There's often a trade-off between precision and some other factor like clamping, and very few machines in the real world are perfectly calibrated. Materials, too, are not perfect objects. Plastics and metals all stretch and shift when they're being machined and it's not uncommon to feel a nasty burr when you remove a part from a machine chuck or 3D printer bed. There's an entire universe of…

Is it a bird? Is it a plane? Is it a tired cliché? No, it's a Raspberry Pi and/or Raspberry Pi Pico flying high up in the sky! These projects defy gravity and send your electronics soaring – sometimes you control it, sometimes you track it, and sometimes you have to get a telescope out to see the vessel it's located in. Grab your aviator goggles and let's take off. 01. Pico 2 Drone Miracle flyer rpimag.co/pico2drone Created by maker intern Louis Wood, who also made the LEGO card shuffler, this drone started with a 3Dprinted body before moving to a less-brittle CNC-routed carbon fibre.
