I’m a big fan of inquisitive people. Especially when it comes to messing around inside computers. After all, being inquisitive about computers is a big part of the Raspberry Pi experience. I’ve just spent the last couple of days overclocking the Raspberry Pi Zero 2 W computer (page 52). With a cooling case and a couple of lines of code; an intrepid editor can get it running from 1GHz to 1.4GHz. A pretty nifty upgrade. Zero 2 W is an incredible new computer. We’ve scoured every project from the last couple of years that involved Raspberry Pi Zero. The result is 40 incredible projects in our Make & Build with Zero 2 (page 34). The last twelve months have been a wild ride on The MagPi magazine. We’ve had Raspberry…

MAKER Simon Richardson A senior electrical engineer at The Little Car Company, who learnt Python on Raspberry Pi. thelittlecar.co One of the most iconic cars in cinema history, the Aston Martin DB5 remains extremely cool to this day – even without the many enhancements that Q installed into James Bond’s vehicle. A real Aston Martin DB5 will set you back an unimaginable amount of money, and won’t even have changing number-plates as standard. If you’re happy with something a little smaller, cheaper, and a bit more eco-friendly, The Little Car Company has a solution for you: the Aston Martin DB5 Junior No Time To Die Edition – which uses some Raspberry Pi magic behind the scenes. “As we needed to control two screens, Raspberry Pi 4 was a logical choice…

01 A user writes a robot command as a message in the livestream chat. This is received by the Droiid Server, parsed as a JSON object, and sent to Raspberry Pi. 02 If it’s a ‘say’ command, Raspberry Pi sends it to a speaker; if it’s a ‘move’ command, it relays it to the Arduino that controls the robot’s motors. 03 Alternatively, Droiid can be controlled manually using the W, A, S, and D keys via a remote web interface that includes the view from its on-board camera.…

MAKER Brankly Brankly is an inventor and entrepreneur. He grew up in Germany and worked as an IT consultant for years before following his passion for inventing full-time. magpi.cc/dogball Dogs love to play fetch and it’s a wonderful way to exercise your pooch. Trouble is, constant ball throwing isn’t half exhausting for human arms, which is perhaps why there’s a growing number of automatic ball launchers on the market. Rather than buy one of those, however, seasoned maker Brankly has created one of his own. “My dog loves to play with blue toy balls and I wanted him to have a little more fun,” he tells us. “I also want him to be able to play fetch when we are busy by encouraging him to load the balls himself.” While…

MAKER Lucy Hattersley Lucy is editor of The MagPi and is taking a much needed break from DIY with actual bricks. magpi/cc Last month we introduced the new Raspberry Pi Build HAT. This new hardware enables you to quickly prototype and build interesting projects with LEGO bricks. The sensors and motors in the SPIKE™ portfolio work fantastically well with Raspberry Pi. Sitting between the LEGO components and Raspberry Pi is the all new Build HAT. This has four connectors used to attach sensors and motors, bringing your builds to life and enabling sensing input and movement. We’re going to be covering LEGO builds in the following editions of The MagPi, and this month we’re going to show you how to get started with Build HAT and perform basic motor control,…

MAKER PJ Evans PJ is a writer, software developer and tinkerer. He keeps several clones of himself in storage just in case. twitter.com/mrpjevans If you’ve been following our home server tutorials over the past months, you should now have a pretty sweet Raspberry Pipowered server up and running, with file sharing, media streaming, remote access, and more. In this final part of our Ultimate Server tutorial, we’re going to look at protecting both your hard work and all that data you have entrusted to our favourite little computer. We’re going to cover the three key pillars of server management: Backup, Reliability, and Monitoring. Luckily, these are not hard to achieve, even for a home setup, and you never know: there may come a day when you’re really glad you took…

> Name Paul Fretwell > Community role Maker > Occupation Software engineer > Twitter @drfootleg Like a lot of great nicknames, Dr Footleg is so named because of a simple mishearing of his surname, resulting in a letter addressed to Mr Footleg. After getting his PhD in Chemistry, he upgraded to Dr Footleg. “I studied science academically, but computers were a hobby right back to my early teens when we got a C64,” Footleg tells us. “When I graduated, I thought working on computers would be something I would enjoy, so I bought a ‘teach yourself to program in 21 days’ book and started applying for jobs 21 days later! I’ve always enjoyed designing and making things. It used to be electronics, before creating designs using computers became a thing.…

MAKER Hendrik Ohrens Full stack software developer Hendrik enjoys playing lacrosse, and making things in his spare time. magpi.cc/robotarminsta Like many of us, 33-year-old software engineer Hendrik Ohrens likes to combine the technical skills he uses for work with those he’s picked up through his hobbies, to come up with something creative. “I love working on projects that involve electronics, mechanics, and software,” he says of his enthusiasm for making things. With a background in scientific research and mechanical engineering at the University of Hannover, plus a few Raspberry Pi builds under his belt, he decided it was time to challenge himself to design his first robot. He decided on a robot arm, since it seemed relatively simple to design but “still has some degree of flexibility”. When Hendrik’s existing…

18 Wearable Time-Lapse Camera This step-by-step walkthrough doesn’t just result in a camera you can use to create a series of time-lapse images – it’s a wearable device that you can attach to glasses or wear around your neck to automatically capture your day. You can either stream them online wirelessly or create a fancy GIF. magpi.cc/timelapse “Capture how a plant grows over time” 19 Time-Lapse Animations Watching paint dry or grass grow are usually given as examples of incredibly dull ways to waste time. Time-lapse animations give the lie to this: train your Raspberry Pi Zero 2 W and HQ Camera to capture how a plant grows over time. Seeds growing, clouds moving, and sunrise to sunset are all rewarding examples. magpi.cc/timelapseanimations 20 LAMP Web Server Mythic Beasts uses…

MAKER Phil King Long-time contributor to The MagPi, Phil is a freelance writer and editor with a focus on technology. @philkingeditor In this series, we are exploring some of the most commonly available sensors and their use cases. Following last month’s fire and gas safety alarm, this time we’ll use sensors to build a different kind of alarm: one to detect intruders. While there are many possible ways to sense the presence of a person nearby, including a PIR motion sensor or camera, we’ll be using a laser beam and sound sensor. When either is triggered, a visual and audible alert will go off. 01 Connect laser sensor Think of all those movies where a secret agent or thief has to get past some lasers guarding an object: break the…

Media centre URL: magpi.cc/102 MAKER: Rob Zwetsloot COST: £10 / $10 minimum, and a spare Raspberry Pi Media centres are mostly software-based, and the simplest ones only require a Raspberry Pi and a case to put them in. The guide we wrote in issue 102 allows you to play retro games, watch movies and TV, and stream shows all in one little box. The cost of parts for that build is around £50 / $60; however, you don’t need everything we used, so pick and choose as your budget allows. For an extra-special treat, make sure it has the info for the recipient’s WiFi network so they can get using it straight away.

▶ The Pi Hut ▶ magpi.cc/epaperpico ▶ From £24 / $28 E-ink displays have long proven useful for portable Raspberry Pi applications with low power requirements where the display doesn’t require rapid updates. Combined with the lower-power usage and tiny footprint of Raspberry Pi Pico, an e-ink display makes an ideal combination for projects like a name badge or weather display. This 3.7-inch Waveshare e-ink display features two female headers on the rear so that you can simply plug in a Pico (equipped with soldered male headers). The graphic on the board makes it clear which way round to orientate Pico to avoid getting the wrong connections. The board also features an eight-pin SPI interface, so can be wired up to a Raspberry Pi computer, Arduino, or another microcontroller. Four…

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’ve 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!! 01. This little fake Tamagotchi is probably a lot more powerful than one of the originals02. Hedgehogs are Features Ed Rob’s favourite animal, so he was very excited to see this03. Raspberry Pi Tower – a place where Raspberry Pi folk work, and also this cool tower of Raspberry Pi04. Flight trackers are a fun way to use Raspberry Pi05. This little handheld will be a great way for students to test their own…

MAKER Eben Kouao Eben builds DIY prototypes based on new technologies. From smart mirrors to delivery robots, you can find more of his projects at smartbuilds.io. magpi.cc/ebenkouao Inspired by the likes of Amazon and Starship, two companies that have both created six-wheeled delivery robots (magpi.cc/amazonscout and starship.xyz), UK-based Eben Kouao wondered if he could possibly build a similar vehicle. As powerful mini-computers become more accessible, Eben started building his own version with a Raspberry Pi and an Arduino, and the result of his labours is Droiid, a clever robot that can be controlled from anywhere in the world. Direct Droiid “Droiid came through the inspiration of recent innovations going on within the delivery market,” Eben tells us. “As online consumer demand increases, to keep up with growing demand, the idea…

MAKER Yoel Nasi A high school student whose team share their passion for programming and making in their community. magpi.cc/pomelogit Robot pets have been around for a long time. Raspberry Pi-powered ones, not so much though. While there are currently no Aibo-a-likes walking around people’s houses, that is probably not too far off. Pomelo is a look at what might be, albeit with an educational leaning. “Pomelo is a dog-shaped educational toy robot that is suitable for primary school classrooms, with the goal of promoting strong algorithmic skills in younger students,” Yoel Nasi – part of the student team that made Pomelo – tells us. “Pomelo can be programmed to move in desired patterns and directions through physical code blocks. The blocks are similar to the regular ‘ABC’ blocks that…

MAKER Jordan von Mulert Jordan is a violin luthier turned mechanical engineer. His passion is learning and making things. When not with his wife and kids, you’ll find him in his workshop or exploring in the woods. We’ve seen a few railway-themed Raspberry Pi projects before, including mini departure boards, but Jordan von Mulert has gone one step further by creating a whole railway map – of Chicago’s ‘L’ elevated railway – lit up with LEDs to show the positions of trains at stations in real-time. Jordan was inspired to make the map after moving away from the Chicago, where he’d lived for ten years with his wife. “Since moving away from the city, we have missed the days of being able to ride the train,” he reveals. “Creating this…

01 Raspberry Pi PC Challenge With a 1GHz quad-core processor, Raspberry Pi Zero 2 W’s CPU is every bit as powerful as a Raspberry Pi 3 (albeit with 512MB RAM). Pair your Zero 2 W with a keyboard, mouse, and screen and it can be used as a capable home computer. For a complete rundown of how to use your tiny new Raspberry Pi as a replacement for a much more power- and space-hungry desktop computer, check out our Raspberry Pi 3B+ PC Challenge in The MagPi issue #59. magpi.cc/59 02 Start coding One big reason many people buy a Raspberry Pi is to pick up some coding skills. And Raspberry Pi OS is packed with programming languages, tools, projects, and tips. Beginners should start with Scratch, a visual language…

29 PolaPi Zero Instantly printing the photos you take allows you to share the memories with those who were in the picture with you. This Raspberry Pi Zero W build additionally lets you send a copy of the shots you snap to an online photo site, so you can retrieve them whenever you wish. magpi.cc/polapizero 30 Dride Zero Dashcam footage is now commonplace, providing drivers and cyclists with eye-witness footage if there’s a prang or unexpected incident. Dride sells ready-made dashcams, but there’s also a build-your-own option if you prefer to put your Zero to good use. magpi.cc/dridezero 31 DIY Hardware Password Keeper So many sites we visit these days require passwords and personal details, that it’s tempting to use the same login for them all. A far safer option…

MAKER Lucy Hattersley Lucy is editor of The MagPi magazine and eggs her little Raspberry Pi to run at ever faster speeds. If only she could run this fast! magpi.cc Raspberry Pi Zero 2 W has a powerful Cortex-A53 quad-core processor running at a default speed of 1GHz. It is possible to give this a boost up to 1.2GHz, or even 1.4GHz. The extra speed makes Raspberry Pi OS more snappy, and comes in useful when setting up Zero 2 W projects that are a little more demanding and could use a little push (such as image processing or retro gaming). There is a chance, however, that Raspberry Pi Zero 2 W will start to overheat and throttle back the CPU, keeping it safe but making Raspberry Pi OS slower.…

One of the goals of the magazine is to inspire people to build things using Raspberry Pi. There’s so much you can do with the various Raspberry Pi computers and Raspberry Pi Pico, and we hope that just one idea lights a spark. Lots of people get a new Raspberry Pi for Christmas, but what if they got some inspiration too? Building something unique and amazing might just be the way to get someone interested, and it makes for an incredibly personal gift as well – especially if they can start using it day-to-day. So, grab some wrapping paper in one hand and awkwardly balance a 3D printer in the other, and let’s get festive.…

More OS Just for your information, as I could not find any mentioning in the recent [operating system] article in The MagPi 111, there is yet another Debian derivate for the Raspberry Pi: Q4OS (magpi.cc/q4ospi). Bernhard via email For those not in the know, Q4OS is a distribution of Linux that aims to offer a classic user interface and only simple accessories and apps. It’s great for cloud development as it has low hardware requirements – something Raspberry Pi can be great at. There are likely other Raspberry Pi operating systems we missed – some are tricky to track down and others aren’t aimed at English-speaking audiences, so are much harder for us to review. If there’s an OS or spin for Raspberry Pi you think we should know about,…

I’ve spent the last few days working with the new Raspberry Pi Build HAT and some bumper packs of bricks kindly supplied. Like most makers, I loved LEGO® as a kid. Either when following instructions to build Technic trucks or working free-form to build planes, houses, or ‘abstract sculptures’. LEGO hadn’t quite become the modern iteration: with its movie tie-ins and themed sets. And it’s been interesting to pick up LEGO again at a later age, and discover just how much of it has changed. Mostly for the better. One thing I love about Build HAT is that it bridges the gap between Raspberry Pi the computer, and learning to code with Raspberry Pi. This is the intersection where The MagPi sits. Many people don’t know that Raspberry Pi is…
