Innehållsförteckning för #151 från Raspberry Pi Official Magazine

rpimag.co This is an incredibly important edition of the magazine formerly known as The MagPi. We've now got full official status and are now known as Raspberry Pi Official Magazine. I love change, but it's important to remember where you are from. So we're keeping everything else familiar to those of you who see this as the 151st edition of The MagPi. If you appreciated our old magazine, you'll love Raspberry Pi Official Magazine. It looks different but is packed with the same amazing Raspberry Pi projects, tutorials, and features. We've got a huge troubleshooting guide updated for Raspberry Pi OS with Debian Bookworm. Armed with this guide, you'll be a better Raspberry Pi maker and builder. We tapped into the Raspberry Pi engineering team for advice and feedback so…

rpimag.co/arnovsharma When you venture outside and take a deep breath, you expect to be inhaling a heap of fresh air, particularly if you're in the countryside. But in truth, you're just as likely to be filling your lungs with pollutants from dirt, dust, pollen spores, gases, and even lead. There's just no getting away from the fact that a good percentage of air can be deemed unhealthy so being able to monitor it on-the-go with a flick of a switch is almost certain to be welcome news. Arnov Sharma has created a handheld air quality meter which can use a Raspberry Pi Pico 2 connected to a gas sensor to display the current levels of a host of hazards. “My Air Quality Meter was created with the intention of measuring…

rpimag.co YOU'LL NEED • Raspberry Pi computer (any 40-pin model) • Raspberry Pi Sense HAT V2 rpimag.co/sensehat A Raspberry Pi single-board computer (SBC) can do a lot of things thanks to its size, portability, and ability to connect to the internet easily. With the GPIO ports you can control electronics and interact with the world. One of the best ways to get started with interaction is by using an add-on like the Sense HAT V2. The Sense HAT is a very sophisticated add-on board for the Raspberry Pi. While 'HAT' is an acronym (Hardware Attached on-Top), it does act in a way like a hat for your Raspberry Pi. The Sense HAT contains a suite of sensors that allows the Raspberry Pi to sense the world around it, along with…

concretedog.blogspot.com In the first part of this two-part mini series, we set out designing various parts for a custom CNC machine that is intended to act as a carbon filament winding machine for making custom carbon-fibre tubes. We got as far as creating a machine bed and frame from aluminium extrusions and then created a sliding bed that would travel the length of the machine on V-slot wheels and also designed a rudimentary tail and headstock idea to create a spindle. The principle of the machine is that carbon tow (a small ribbon made up of thousands of carbon fibres) will be wrapped off a reel onto a mandrel (a small tube) with epoxy applied. The tow will be applied to the mandrel in patterns of movement where the mandrel…

Safety Tips Here's how to help protect yourself and others 1. Safety goggles Eye protection is important! Flying shards and splashing chemicals can be really damaging. 2. Proper space Make sure you have plenty of suitable space for your project, along with safety gear for anything that might catch on fire. 3. Do your research Read the manual, read the reddit, make sure you know how something works and the dangers it may represent before using it.…

3D printer accessories Spudgers, nippers, scrapers, brushes, tweezers, files, and more are very helpful for getting your 3D print off the bed, and then cleaning it up ready for use. You can get sets anywhere you can buy a 3D printer, and also on Amazon. 3D software Designing prints yourself can be fairly simply depending on what you're trying to make. Free web-based software such as Tinkercad (tinkercad.com) is quite powerful. If you need to make something more elaborate, Fusion 360 (rpimag.co/fusion360) is a popular option. Models need to be sliced as well – a process of telling the printer how to print the model – and 3D printers usually have slicing software recommended for the model. PLA printer Price range: £300-£2000+ / $400-$2500+ This traditional type of 3D printer…

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. This issue we're saying goodbye to #MagPiMonday, and welcoming in the new #MakerMonday, so remember to follow along at the hashtag #MakerMonday! 01. The train set gets yet more upgrades, thanks to a bit of experience 02. The electronics in a game like Operation may be simple, but that doesn't make the buzzer any less scary 03. It's so powerful it's emitting lightning! Wow! 04. An interesting new take on a voice assistant 05. A nice, more robust, and probably cheaper alternative to the Sony frame, we say 06. We love truly autonomous robots, and they're only getting more powerful. 07. As usual,…

As well as being features editor of Raspberry Pi Official Magazine, I've recently taken on a new role: tech support. Unpaid tech support to my parents, that is. They recently had a computer fail on them, and were about to buy something grossly over-specced and over priced to replace it. I kid you not, they even asked me whether I'd recommend a Mac. Of course, as they already had a mouse, and a screen, and a load of cables, there was no need to spend ridiculous sums of money on a machine destined to word processing, email, and web browsing. They've now got a perfectly functional Raspberry Pi 500 doing the job, which for them also comes with free tech support including home visits. All this goes to illustrate the…

shapingthesilence.com Musical instruments are dependent on physics and maths for their sounds. A guitar string changes pitch when its physical properties change, be that string thickness, tension or length. A note from a saxophone, or any wind instrument, changes according to the length of the instrument that the air is vibrating through. Any physical instrument needs to have some physical property that the player must interact with in order to play music, and this naturally limits who can play, and what can be played. At least, that's how it always was. With MIDI and computers, this no longer has to be true. The instrument that you play is nothing more than an input device, like a keyboard and a mouse, and as such, it can be any shape or size…

rpimag.co/piboard California high school student Tamerlan Goglichidze has been coding and building projects since he was 11, teaching himself essential skills using online videos and tutorials before progressing from virtual to physical creations once his knowledge base gave him the confidence. This early focus would be impressive enough in itself, but Tamerlan was also busy taking on all-comers as a chess player who travelled extensively to compete in International Chess Federation matches. His Raspberry Pi Chess Board combines the two interests. Winning strategy He chose Raspberry Pi 4 as “the brain of the system, bridging the digital chess world with physical movements on the board”, noting its ability to handle advanced and complex systems as well as the versatile OS and accessible GPIO pins. Tamerlan felt it “was the best choice…

rpimag.co/WhisperingWires Here's a true work of art: a build designed to be useless; to do nothing other than bring beauty into your life. The maker was looking around a flea market one day, came across an old telephone handset, and wondered to himself: “What if those silent wires could whisper again?” Thus began this wonderful project, called Whispering Wires, which takes a phone and uses a Raspberry Pi Zero W to add poetry. Maker Rootkid (aka Théo Z V Champion) started with a Socotel model S63, which was the standard issue phone in France in the '60s. This model was built to last and, crucially for our purposes, built to be repaired, so everything can be taken apart and put back together again. He needed the phone to be connected to…

@mrpjevans YOU'LL NEED • Private cloud server  rpimag.co/144 rpimag.co/145 rpimag.co/146 rpimag.co/148 • Domain name • Static IP (or DuckDNS setup) There's been a lot of talk about centralised services on the Internet. Companies such as X or Facebook have closed systems and hidden algorithms that control what you see. The Fediverse, backed up by the ActivityPub protocol, was designed as a true decentralised system that no one organisation can control. Mastodon, the Fediverse microblogging platform, has come to the fore as a real alternative for those who take their privacy seriously. In this final part of our private cloud server series, we invite you to join the Fediverse. We'll use CasaOS (casaos.io) from the previous instalments and use Docker to create our instance. 01. Introducing GoToSocial Although Mastodon is typically the server people…

@holtonhandmade Dehydration as a food preservation technique is as old as the hills, a way of extending the life of foods because, if the moisture is removed, this obviously inhibits the growth of bacteria, mould, fungi, and all those microorganisms that can cause decay when a food is left uneaten for too long. Dehydrating foods is very easy to do, and you can create some lightweight and portable snacks – great for when you are out walking or camping, for example. The dehydrated form of the foods we will consider still holds a high percentage of its nutritional value. It's also a way of reducing food waste when you have bought (or grown) too much of a particular food, with the added benefit that the taste of many dehydrated foods…

Kevs Robots kevsrobots.com With regular appearances in Raspberry Pi Official Magazine, Kev is well known in the community for tons of great robotics projects using a Raspberry Pi computer or Raspberry Pi Pico. He includes videos and write-ups for his various builds – including tiny turtle robots, moving robot faces, and a robot that will give you a high-five when you need one. Raspberry Pi Projects site rpimag.co/projects The Raspberry Pi Foundation's project site is full of great tutorials for people starting out, covering a broad range of programming, building, robotics, and even 3D modelling in Blender. Several of the projects work as a series, allowing you to build up your skills as you go. Raspberry Pi forums rpimag.co/forums Got a burning question about an error and not sure how…

Adafruit > £17 / $18 | adafruit.com As used in the Photon 2 Lander project showcased last issue, this lovely little LCD has vibrant colour. The only caveat is that since the LCD was designed to be used in smartwatches, you should add your own plastic or glass overlay to protect it. While the EYESPI port on the rear is for an FPC ribbon cable, there's also a breakout header for connecting it to Raspberry Pi or Pico using seven individual pins and the SPI protocol. Since the display has a built-in frame buffer, it works well even with smaller microcontrollers with little memory of their own. The LCD itself is of the TFT (thin-film transistor) kind and uses IPS (in-plane switching), which means the viewing angles are great: up…

downingsbasement.com For the past 15 years, Chris Downing has been part of a community that takes old TV console games and turns them into portable versions using original hardware wherever possible, posting details on his site, Downing's Basement (downingsbasement.com). Raspberry Pi had “always been in the scene”, with many hobbyists using it to make portable emulation handhelds, “which in its own right was very cool”, says Chris, even though it was against the group's “purist original hardware culture”. Nonetheless, when it came time to create his own Doom-playing Mini Air Hockey Table and scoreboard, he instinctively turned to Raspberry Pi. Multicoloured swap shop A change of company gave Chris access to bigger and more robust CNC routing tools and large flatbed printers, while a Yankee swap at the office party netted…

rpimag.co/fruitbox It's always good to come across a project that you can really make a song and dance about. And, in the case of this awesome, authentic-looking jukebox based around a Raspberry Pi 4 computer, that's exactly what we've been doing. Maker Jeremy Childress has harked back to the 1950s for his first Raspberry Pi project, producing a machine that makes great use of a popular customisable MP3 player called Fruitbox. He's done so at a fraction of the price it would cost to buy and fix up a retro jukebox while having lots of fun in the process. “My mom has always wanted a vintage jukebox and several years ago, my parents bought an old Seeburg DS160 that never worked right,” Jeremy says. “I tried messing with it a…

rpimag.co/dungeonsynth Continuing from last month's guide to setting up an acoustically treated recording space at home, it's time to get to the hardware. Quieter than an actively cooled Raspberry Pi 5 setup in most cases, Raspberry Pi 500 is a great studio computer (other Raspberry Pi 4, 400 and 5 models also work well, if you use a silent case or no fan), but you'll need a little more equipment than that. Audio interfaces You'll need an external audio device. For basic voice recording, we've successfully used a pocket-sized consumer USB DAC (AudioQuest DragonFly Red, £135) and a USB microphone. This is enough, with the right software and driver setup, to handle vocal and spoken word recording, editing, and mixing without any quality or latency issues. More sophisticated productions require…

Making is one of the most fun hobbies in the world, even if we do say so ourselves. It also encompasses so many things – from simple circuits and humble sewing to futuristic 3D printing and postapocalyptic metalwork, you can express yourself in so many physical ways. If you're new to the hobby, it can be tricky to know where to start – so we've put together a guide to help you get started on your maker path with some universal (and some less universal) tools and resources. What will you make?…

Workmate An indispensable alternative / addition to a workbench with holes and a split so you can drill through things without drilling into a desk, or saw through things without cutting into your workbench. G clamps When you need to hold two pieces of anything together firmly, and it would be two awkward in your vice. Great for woodwork and for allowing glues to set and cure overnight. Hacksaw Need to cut some metal? A hacksaw is suited for the task over a regular saw, especially when you don't have access to a big mitre saw. Saw When you need to cut some wood, a classic wood saw will see you through. Mitre boxes that help with cutting at specific angles are a great addition to a saw as well…

Some projects require an on-board display to show data, especially when it's not practicable or desirable to hook the device up to a full-size monitor or larger touchscreen. There are countless mini displays available, coming in various sizes, types, price ranges, and even different shapes. Some are HATs that mount directly onto a Raspberry Pi computer's GPIO pins; others are designed to be mounted on a Raspberry Pi Pico. Many displays are connected via individual pins, using protocols such as SPI or I2C, offering greater versatility as they can be used with a range of devices. You can even get mini displays with a standard HDMI connector. As mentioned, there are several technology types for mini displays, including LCD, OLED, and e-ink. Adafruit even used to sell a couple of glowing…

Waveshare > £11 / $10 | waveshare.com An alternative to an LCD screen is an OLED (organic light-emitting diode) one. Based around an organic compound film that emits light when an electric current is passed through it, this results in a bright display without the need for a backlight. That's why the tech is also used in many high-end TVs. This 1.3-inch example is monochrome and limited to a 64×128 resolution, but offers great value for money and is fine for showing info like sensor and weather data. It's designed to be mounted onto a Raspberry Pi Pico (with pin headers attached), so is fairly easy to set up and program with MicroPython, C/C++, or Arduino IDE. It uses the SPI protocol by default, but can be switched to I2C…

Name Chuck Keith Occupation UC engineer Community role YouTuber URL rpimag.co/networkchuck YouTubers can come from anywhere. In Chuck of NetworkChuck's case, he sold toilets. However, growing up he'd been a bit of a tech kid. His dad was in IT and would being back old hardware that both would tinker with. “I got back into tech – partly out of necessity and maybe a little bit of survival,” Chuck says. “My wife and I had just had our first daughter, and the pressure to provide was getting real. In between sales calls, I would crack open my CompTIA A+ study guide, hoping to earn my first IT certification and land my first job in IT. And that's exactly what happened. I started as a junior helpdesk support specialist (I didn't…

Raspberry Pi Official Magazine As one can see on pages 128 and 129 of The MagPi magazine issue #150 (magpi.cc/150), starting with the next issue, 151, The MagPi will now simply be named Raspberry Pi Official Magazine. This raises some questions: What will happen to MagPiMonday? Will the magpi.cc domain still work in the future? Is it safe to rename a magazine in times where print magazines are on a decline? Stl1988 via the forum We really enjoyed the vibrant chat that you sparked on our forums (rpimag.co/forums) about our new name. And we hope you are enjoying the new magazine now that you have a copy. In answer to your questions, we are going to use #MakerMonday. And yes, the old magpi.cc link still works, and we are using…
