Robots are a true passion here at The MagPi. Few things you make with computers have the same potential to impress as a walking, wheeling, or even talking 'bot. The real skill isn't just building a robot that rolls around, but creating a smart rover that can sense its environment and react accordingly. These rovers are sent into hazardous environments, or even to other planets. Our robot explorer feature (page 40) has everything you need to get rolling. Have fun building your robot, and don't forget to give it a name. And when you're done check out the new AI Kit (page 8). This new Raspberry Pi kit offers the potential to vastly speed up artificial intelligence projects. We can't wait to start making with it, and I know our…

MAKER Arvind Sanjeev Arvind is a design technologist who loves to experiment between the boundaries of the physical and digital. magpi.cc/spin Danger! Mains Electricity This project involves disassembling a mains-powered record player. magpi.cc/electricalsafety “My idea was to remove AI experiences from black boxes and put them into the physical world,” says Arvind Sanjeev. “It's an open invitation for people to forget about the digital world and to try to create something with AI.” His previous project was Ghostwriter, a typewriter which he converted to use text generator ChatGPT. Humans type their messages and Ghostwriter types its replies onto the same sheet of paper. He wanted to create a family of devices and was thinking about where else AI has been disruptive. “The latest music AIs have become so good that…

MAKER Matthew Allard Puttr CEO Matthew has worked on mobile software and for AOL on smart home development. This is his first Raspberry Pi project. puttr.co Executive boardrooms up and down the land are (according to urban myth or business tropes) stuffed to their expensive gills with bag after bag of golf clubs; their owners while away the working week so they can head off to the fairway and execute some impressive swings and putts. What joy to learn of a miniature putting mat that puts those otherwise idle clubs to good use mid-week too. Puttr (puttr.co) makes excellent use of Raspberry Pi 4 and an HQ Camera to determine whether a putt is made or missed, logging results on a linked app. Like many great ideas, Puttr came about…

We've done a couple of kitchen-y cookery sorta tutorials and features in the past because, well, there are many expensive cooking gadgets and it would be cool if you could make something similar for a fraction of the price. This is where Raspberry Pi comes in, with these ten excellent projects. OnionBot Perfect caramelisation Using computer vision, this project keeps an eye on your food while you're otherwise distracted, controlling the power of an induction hob. It was originally made to help create perfectly softened onions. magpi.cc/onionbot Food burning detection Pico smoke detector Instead of using cameras to detect how your food is cooking, this Pico project uses various gas sensors. You really shouldn't step away from a lit hob though. magpi.cc/burning Raspberry Pi Microwave QR cooking 'Food should have a…

FIND OUT ABOUT NEXT MONTH'S EVENTS AND POP-UPS ON PAGE 92 Held at Leicester Hackspace, this event focussed on camera projects, with members of the hackspace old and new (and lapsed!) coming along to see some cool projects. Here's a small report from the event organiser Steve Gale. “The All Sky camera was popular, with images from Leicestershire, plus some photos taken in South Australia with an identical device, We were all jealous of the photos of the milky way! We also had a Raspberry Pi 5 controlling a servo using gestures, based on one of “Kevs robots” projects, plus a USB controlled arm. Another member set up retro-pie. Our youngest member Anna showed off her nature cam using a Raspberry Pi Zero W.”…

It looks like a game controller but for visually impaired people this dice-rolling device is actually a game changer as David Crookes discovers MAKER Christopher Hall Christopher Hall is a Senior Network Engineer from Pikeville, KY, USA. He's a maker at heart and lover of all things geeky. magpi.cc/dm2000 Chris Hall enjoys playing board games and he's part of a local gaming group. He attends with his best friend and the pair have had many happy times but a medical condition affecting his pal's vision has threatened to spoil the fun. “About a year ago, my best friend was diagnosed with a degenerative eye disease,” says Chris. “So when his birthday was coming up, I wanted to do something special for him.” Most of the games played by the group…

MAKER Divya Chandana A Texan senior software developer who also loves to collect rocks and crystals, build LEGO, and explore technology magpi.cc/mathgpt The uses of LLMs with Raspberry Pi have been quite staggering – many of which we've covered here in the magazine. From recipe bots to interactive story tellers, and compliment givers to fortune tellers, the uses seem endless. Maker Divya Chandana has brought us a new one: an educational toy that helps children learn maths. “Unlike traditional math exercises, this interactive game transforms equations into relatable scenarios, such as 'two candies + three candies,' and can dynamically change objects with each question to maintain engagement and curiosity,” Divya tells us. “The game utilises ChatGPT to generate questions, seamlessly adjusting difficulty as children progress in the game and featuring…

Dr Andrew Lewis Dr Andrew Lewis is a specialist fabricator and maker, and is the owner of the Andrew Lewis Workshop. QUICK TIP If you want to delete the last item scanned, use the BACKSPACE key. If you have text in the register's buffer, it will delete the last character typed. If the buffer is empty, it will delete the last line item added to the current sale. The world of the future is a largely cashless society, but the world of today still uses metal tokens and paper promises to facilitate transactions. In an urban store you'll probably find an electronic point of sale (EPOS) system that handles the shopping experience, but when you're on a market stall away from regular power, the conventional EPOS experience isn't as easy…

MAKER GurgleApps Amelia, Caleb, and Zivya are the three-person team of GurgleApps, a STEM YouTube channel focusing on electronics that has been going for years. They're also siblings. magpi.cc/colwordclock Gurgle Apps has been making fun electronics projects (and tutorial!) videos for years now, and we've included what they've made in the mag several times. The three siblings Amelie, Caleb and Zivya are back again in these pages with a kit that you can actually build yourself – the Colour Word Clock. “One of our first ever projects was a tiny 8×8 LED matrix word clock using a Raspberry Pi,” the siblings explain to us. “At that time we were too young to do it on our own, our Dad made it to teach us a bit of Python and electronics.…

MAKER David Edwards David Edwards has been tinkering with electronics from a young age and he presents insightful videos for Element14. magpi.cc/retromirror Many hobbyists have used Raspberry Pi to create a magic mirror or a retro games console. But, as David Edwards has shown, it's possible to do both at the same time, taking the concept of a magic mirror and a console to a whole new, playful level. “I have long wanted to build a magic mirror,” David says. “It's a great way to access common information that would otherwise be locked on a smartphone. I have also liked wall-hanging small arcade machines, but I have neither the space or permission to install one! The solution, for me, was to combine both concepts into one device.” With that in…

MAKER Nate Contino Nate is a retrofuturist and writes documentation for Raspberry Pi. lambdalatitudi-narians.org The M.2 HAT+ adapter board converts between the PCIe connector on Raspberry Pi 5 and a single M.2 M key edge connector. You can connect any device that uses the 2230 or 2242 form factors. The M.2 HAT+ can supply up to 3A of power. The M.2 HAT+ uses Raspberry Pi's HAT+ specification, which allows Raspberry Pi OS to automatically detect the HAT+ and any connected devices. The included threaded spacers provide ample room to fit the Raspberry Pi Active Cooler beneath an M.2 HAT+. The M.2 HAT+ is only compatible with the Raspberry Pi Case for Raspberry Pi 5 if you remove the lid and the included fan. “Ensure your Raspberry Pi runs the latest…

INTERVIEW > Name Brian O'Halloran | > Occupation Brand Manager > Community role Raspberry Pi visuals | > URL raspberrypi.com We've been working with Brian ever since he joined Raspberry Pi as a photographer and videographer – both for covers, photos, and fun videos. We should get back to those videos one day, but his creativity and expertise have not only elevated the magazine but also everything you see out of Raspberry Pi. “My career was born out of utter post-school indecision,” Brian admits. “I studied multimedia at uni, and even though it involved studying things like web development and data science, I decided that messing around with a camera was surely the most fool-proof way to make a living. I moved to Vancouver to ply my trade, and was fortunate…

Upgrade worries I'm worried, and maybe others are too. Or have I misunderstood something? I have a nice Raspberry Pi 5 8GB with M.2 HAT+. I'm booting from the M.2 and took out the microSD card. So I've loaded up Apache and MySql and some web pages and various other software and lots of MP3s, and am about to play with AI. I'm running Bullseye… but what happens when I want to upgrade to Bookworm? The recommended route seems to be to use Imager… but won't I lose everything I installed? I'm not sure I'm up to a manual update – possibly rpi-update – but I'd feel safer doing that and a backup with you holding my hand. Can you show me (and others) how please? Paul via email Updating…

THE FINAL WORD If you've been reading the financial papers over the last few months, you'll have been aware that Raspberry Pi was looking to float on the stock market. This is, understandably, quite a big deal, so when I got the email sent around to staff asking if they'd want to go to the London Stock Exchange for 7:45 AM on a Tuesday morning for the launch, I gracefully… declined. Unfortunately, my car was due to be returned to me after some repairs (hit and run on the motorway at 70; I was fine, my car not so much), and also, I didn't really fancy getting up at 3am to get to London in time. Lucy went though, so there was The MagPi representation there for the big moment…
