Artificial intelligence is blazing hot at the moment. Raspberry Pi has gone from having not one, but two incredible AI products in the space of a few months. In issue 143 we revealed AI Kit; this month we're proud to cover AI Camera. AI Camera looks like a regular Camera Module but has a Sony IMX500 Intelligent Vision Sensor that runs neural network models on the camera. It connects to Raspberry Pi using the ribbon cable, which leaves the board free to control hardware. Meanwhile, your AI Camera provides object and pose detection, and you can train AI models. To celebrate we've gathered together some of the best AI projects from the community, and put together a how-to guide to using your new AI Camera. Raspberry Pi is a whole…

MAKER Our Maker In Residence intern, Louis, has spent the summer making all sorts of cool Raspberry Pi builds. magpi.cc/louiswood This project was inspired by Nixie tubes, an old technology used for displaying digits. The trouble with Nixie tubes is that they are quite dangerous, requiring 170 volts to produce their characteristic glow, and very expensive, since they are no longer mass produced. A safer, more modern approach is using LEDs to light the edges of engraved acrylic. Electronics The electrical design of this project is simple and uses a single 300-LED-long strip of NeoPixels, a Raspberry Pi 4, and a 5V power supply. To provide ample current to the Raspberry Pi and the pixels, I went with an 8A supply. While there are only a few electrical components a…

HackSpace | TUTORIAL Nicola King is a freelance writer and sub-editor. ‘Buttony' is officially her new favourite hobby, and buttons will now be added to everything she makes! Try to imagine, for a moment, where we would be without buttons and other textile fastenings. How would we keep our bags secure, our clothing and coats fastened against the elements, or our shoes on our feet? There are countless types of fastening to hold textiles together, and we cover some of those later in this article. They clearly have an important functional use, but buttons and fastenings don't just connect things. Many also provide a non-utilitarian decorative flair to clothing, for example, enhancing the look of a garment or a bag. Deeper than that, though, is the history, the heritage that…

▶ Pineboards ▶ magpi.cc/hatdrivenano ▶ £9 / $10 SPECS FEATURES: Power and activity lights; 25mm PCIe FPC cable; 3A buck converter SSD SIZES: M.2 2230, M.2 2242 Verdict An inexpensive, smaller M.2 HAT with no loss in performance. 8/10 Big doesn't always mean better, as proven by the HatDrive! Nano, which at 55×34mm is about half the size of most M.2 HATs. This means it'll fit inside the official Raspberry Pi 5 case, albeit with the fan section removed. The good news is that, elevated by a couple of standoffs, the Nano can work alongside an Active Cooler. Some other M.2 HATs can do likewise, but this smaller board leaves most of the Cooler's fan unobstructed so cooling performance should be slightly improved. The GPIO pins and camera/display ports are…

Every Monday we ask the question: have you made something with a Raspberry Pi over the weekend? Every Monday, our followers send us amazing photos and videos of the things they have made. Here's a selection of some of the awesome things we got sent this month – and remember to follow along at the hashtag #MagPiMonday!…

“The AI Camera is built around a Sony IMX500 image sensor with an integrated AI accelerator” People have been using Raspberry Pi products to build artificial intelligence projects for almost as long as we've been making them. As we've released progressively more powerful devices, the range of applications that we can support natively has increased; but in any generation there will always be some workloads that require an external accelerator, like the Raspberry Pi AI Kit, which we launched in June (magpi.cc/aikit). The AI Kit is an awesomely powerful piece of hardware, capable of performing 13 trillion operations per second. But it is only compatible with Raspberry Pi 5, and requires a separate camera module to capture visual data. We are very excited therefore to announce a new addition to…

MAKER A Miami highschooler and YouTuber, Connor competes in robotics competitions and also runs cross country. magpi.cc/garagerobots We've all been there. You see a tough dirty spot and think ‘ah, if only a robot could do it for me'. Or is that just us? Well, the thought did occur to Connor at least: “I first thought of [my project] because of a dirt patch on the concrete in my backyard,” Connor tells us. “Initially, I wanted to just use a regular old pressure cleaner, but then I thought how much easier and less time-consuming it would be if I could relax and watch a robot do the job for me.” Over the course of a few months, Connor built that robot, a device to automatically clean a space measuring two…

MAKER Data scientist Noah Kasmanoff is fascinated by technology to make people's lives easier and was drawn to Raspberry Pi due to its very accessible applications. magpi.cc/picardgit As an astronomy and physics student, Noah Kasmanoff ran Python simulations to help design scientific instruments. As a data scientist, Noah is interested in how technology makes our lives easier, and recently set about creating an AI assistant to he lp us spend less time on our phones. The result, Pi-CARD, is far from the only Raspberry Pi AI assistant, but it's the first one we've encountered whose name pays tribute to the legend that is Jean-Luc Picard. Noah's aim with Pi-CARD (Camera Audio Recognition Device) was to see how useful he could make an AI assistant that runs entirely on a single…

Let there be light! Whether you want to create mood lighting for areas of your home or add some blinkenlights to projects, LEDs are the key ingredient. They come in many different types and form factors, from long flexible strips to matrix grids – also good for digital signage – and a range of shapes. In this Best of Breed, we're throwing a little illumination on LED lighting options. While flashing a solitary LED is the Hello World of physical computing, there are far more interesting things you can do once you have a bunch of LEDs to play with. Single-colour LEDs have their uses, but for the best results you'll want some RGB (or RGBW) ones that can light up in any shade. Ideally, each LED should be individually…

It's nice to dress up, even if you're a microcomputer like Raspberry Pi 5. There are many options to choose from too - from traditional cases that keep Raspberry Pi 5 suitable for your desk or under your media centre, to retro console look-alikes and all-in-one screen/tablet cases. Here are ten we like, some of which you can make with a 3D printer. Official case Eben approved A simple yet stylish and effective case, this layered plastic enclosure also includes an active cooling fan and also comes in black. magpi.cc/case I £10 / $10 3D-printed case 3D simplicity This 3D-printed case even comes with a button you can use with the actual Raspberry Pi 5 power button, space for the Active Cooler, and plenty of ventilation. magpi.cc/rpi53dcase I Free Swap Pi 3Dprinted…

Identified flying object I was very interested in David Miles' joystick article in Issue 146 (magpi.cc/146). I flew the Panavia Tornado F3 as a Royal Air Force navigator in the 1990s, and also spent time on the aircraft in the service software maintenance team. So, I'm sure that the two joysticks are working replicas of the pilot's control column and the navigator's radar hand controller (used to steer the radar scanner and perform other radar-related functions). The equipment is clearly not from an actual aircraft, and neither myself nor former colleagues that I've asked are sure where it was used. My best guess is either the crew training simulator or a ground test rig. Will you please congratulate David on his ingenuity, share this information with him, and tell him…

THE FINAL WORD Next year, I have the feeling I'm going to be doing a lot more long-distance travelling, and that always gets me wondering about how I am going to entertain myself during these journeys. I actually have a pretty good system down – a tablet with books loaded on, a console with a game backlog (sometimes this does mean a 3DS), and hoping there are some cheesy movies I've not seen if I'm flying. I've got a new tablet recently which actually has a decent amount of storage too, so I can finally download shows from streaming services. A revolution. This recent change got me wondering how else I could mix up the travel tech and, of course Raspberry Pi came to mind. In fact, Raspberry Pi could…

MAKER Swedish embedded systems engineer Anders uses Linux daily and enjoys restoring gadgets and old computers to working order. magpi.cc/brstester Anders Sandahl loves collecting old computers: “I really like to restore them and get them going again.” For this project he wanted to build a kind of a component tester for old DEC (Digital Equipment Corporation) Flip-Chip boards before he embarked on the lengthy task of restoring his 1966 PDP-9 computer – a two-foot-tall machine with six to seven hundred Flip-Chip boards inside – back to working order. His Raspberry Pi-controlled DEC Flip-Chip tester checks the power output of these boards using relay modules and signal clips, giving accurate information about each one's power draw and output. Once he's confident each component is working properly, Anders can begin to assemble…

MAKER High school student Andrew Zhang has been programming since 6th grade, and has a passion for creating cool software and using hardware to bring it to life. magpi.cc/smartpillvid Every year, the Raspberry Pi Foundation runs and helps judge Coolest Projects, a competition in which young coders and makers from around the world are encouraged to use technology in innovative ways. Among the hundreds of entries to this year's Coolest Projects challenge, 15-year-old Andrew Zhang's Smart Pill Dispenser stood out for the considered approach to solving a problem he'd encountered first-hand – his grandmother sometimes forgets to take important medications, and Andrew's informal research among her peers indicated it was a fairly common scenario – as well as the way he went about designing a means of solving it, using…

MAKER Nate is a retrofuturist and writes documentation for Raspberry Pi. lambdalatitudinarians.org You'll Need > Raspberry Pi > Raspberry Pi OS Instead of the BIOS found on a conventional PC, Raspberry Pi devices use a configuration file called config.txt. The GPU reads this file before the Arm CPU and Linux initialise. Raspberry Pi OS looks for this file in the boot partition, located at /boot/firmware/. You can edit this file using Nano (magpi.cc/nano). Open a Terminal window and enter: … or to use Vi (magpi.cc/vi): In this tutorial we'll take a look at some of the configuration settings you can adjust in the default config.txt file. There are many further configuration settings available. For more detailed information on settings see our Raspberry Pi documentation page (magpi.cc/config.txt) You can edit config.txt directly…

Rob has been playing with hardware and software since almost before there was hardware and software. robmiles.com. This project lets you create the unique experience of being hounded by the paparazzi. It uses CircuitPython code running in a Raspberry Pi Pico to control servos that make a camera notice you when you walk into the room, then track you. This project started when the author acquired 15 broken point-and-shoot 35mm cameras which were purchased to obtain just one camera which was part of the package. However, once all the cameras had been received, tested and found to be properly broken thoughts turned to what to do with them. The original plan was to use nine of them to create an installation in which all the cameras followed you around the…

With a house and shed full of lathes, milling machines, 3D printers and more, Jo (AKA Concretedog) 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. A CNC lathe is something I've always wanted. I've operated manual lathes a fair amount, and I've used CNC mills and routers, but I've always pondered how CNC lathe operations work. As I had no project in mind for it I didn't want to spend a fortune on a pre-built CNC lathe, so I set out to convert one. The lathe in question is a small hobby lathe called a Unimat 3, seen in Figure 1. Unimat, part of the larger EMCO company, produces lots of…

Being able to anthropomorphise an automaton so that it looks more friendly, and in this case very cute, can really help with interaction. While Pibo is not the first bipedal Raspberry Pi robot, there aren't many of them and none as advanced as it. Pibo comes in two versions – an AI assistant version that you can talk with and interact, and one more suited…

INTERVIEW > Name Kari Lawler | > Occupation Tech entrepeneur and consultant > Community role YouTuber | > URL magpi.cc/kari Kari Lawer has a passion for retro tech – and despite being 21, her idea of retro fits with just about everyone's definition, as she collects and restores old Commodore 64s, Amiga A500s, and Atari 2600s. Stuff from before even Features Ed Rob was born, and he's rapidly approaching 40. Kari has been involved in the tech scene for ten years though, doing much more than make videos on '80s computers. “I got my break into tech at around 11 years old, when I hacked together my very own virtual assistant and gained some publicity,” Kari says. “This inspired me to learn more, especially everything I could about artificial intelligence.…
