MAKER Aula Jazmati Aula has a doctorate in electronic engineering and uses her Raspberry Pi projects to inspire other makers magpi.cc/aulaj Syrian electronic engineer Aula Jazmati was amazed when she encountered her first Raspberry Pi in 2014. “It was like a miracle in a country suffering from difficult circumstances”, so much so that Aula set about sharing the joy with students and children as a means to inspire their love of making. Many Raspberry Pi and Hexabit projects later, Aula decided to take on a more whimsical creation – a Pico Bubble Machine – figuring “soap bubbles have always fascinated children and adults alike. They bring joy and excitement, creating beautiful floating spheres that reflect light in mesmerising colours.” This DIY project also offers an exciting opportunity for children to…

MAKER Levi Maaia A researcher, film-maker, and educator, Levi likes to tinker with tech and learn about the people who tinker with it too pathwaystoinvention.org I f you’ve ever lived near the sea, you’ll know that it never gets old to walk along the beach, especially when the weather is good. For Levi Maaia, it turned out the weather wasn’t the main problem. “I live 200 feet above the Pacific on an ocean cliff,” Levi explains. “I try to make it a weekly ritual to walk down the cliff to the shore. However, it’s disappointing to reach the seaside stairs, expecting a nice sandy walk, only to find waves lapping against the base of the bluff.” For us landlubbers, tides aren’t always something we have to think about, although Levi…

CAMJAM EDUKIT 3 PRICE £20 / URL magpi.cc/edukit3 This is our go-to recommendation for a robot kit for beginners – it’s low cost and easy to program, and the coding and components can be used in future, bigger robot projects. It works with just about every kind of Raspberry Pi (and probably with Raspberry Pi Pico if you’re a bit more experienced) and there are a few 3D printable chassis for it if you’d rather not use the cardboard box it comes in as its frame. AUTONOMOUS ROBOTICS PLATFORM FOR PICO PRICE £41 / URL magpi.cc/autorobot If you have a Raspberry Pi Pico and you’re interested in robotics, you can’t go far wrong with this kit from Kitronik.

MAKER PJ Evans PJ is a writer, software engineer and tinkerer. He once pranked a colleague by using VNC to randomly change his desktop image. You should not do this. mastodon. social/@ You’ll Need > Raspberry Pi > Raspberry Pi OS Bookworm > Computer with TigerVNC Viewer tigervnc.org As is so often the case in computing, a new version of an operating system brings advancements but also some compatibility headaches. The old X11 window system that is the underlying engine of the Raspberry Pi desktop has grown too restrictive, so Raspberry Pi OS Bookworm has moved to the new whizzy Wayland engine. Wayland is a great and necessary step forward, but If you want to remote control your desktop using VNC, you need to move to a service that understands Wayland and…

Every time a new Raspberry Pi is released, there are questions about thermal control of the new board. People want to Know whether it's necessary, and if so, what you'll need to do to make it happen. For normal usage of your Raspberry Pi, adding cooling is entirely optional. The idle performance of a Raspberry Pi 4 and a Raspberry Pi 5 is about the same, and under typical loads, Raspberry Pi 5 will run cooler than a similarly loaded Raspberry Pi 4. However, a heavy continuous load will mean that the board could potentially go into thermal throttling. Throttling happens as there are software controls to limit CPU speeds if things get start to get too toasty. Although, even when fully throttled, a Raspberry Pi 5 is still going…

MAKER Dmitry Grinberg Dmitry is a tinkerer from Austin, TX who specialises in squeezing every cycle out of microcontrollers magpi.cc/repalm You can’t run Raspberry Pi OS on a RP2040 microcontroller, but that doesn’t mean Raspberry Pi Pico is too underpowered for an operating system. As Dmitry Grinberg has shown, it’s capable of running a port of the classic PalmOS 5 – the mobile operating system unveiled in 2002 – although it’s not been without considerable effort. PalmOS 5 was the first version of Palm’s operating system to support ARM devices. Before that, the OS, which dates back to 1996, ran on the Motorola 68K processor line. “The move to ARM was a bit more interesting,” Dmitry says. “There were rumours about the large internal re-architecting of the OS at the…

MAKER Thomas Ackermann A software engineer since the ’90s, Thomas started his career writing C on Unix systems. magpi.cc/pihome In the current climate, saving money on heating is something a lot of people are interested in doing, so it’s no surprise that someone decided to tackle this head on using Raspberry Pi Pico W. “I’m using temperature and humidity trend data for optimising my heating systems and monitoring individual room temperatures and humidity,” Thomas Ackermann tells us. He lives in Bavaria, which has a similar climate to the UK with distinct seasons and a temperature ranging from freezing in the winter to too hot (25-30°C) in the summer. “Up until now I have had three systems running: two systems for room monitoring which I am using for rooms which are…

FEATURE CHOOSE A 3D PRINTER With so many 3D printers to choose from, its best to ask the experts, which in our mind is our colleagues on our sibling publication HackSpace magazine. Issue 59 (hsmag.cc/59) has a guide on building an open source 3D printer, as well as reviews of 3D printers throughout its other issues, such as the new Prusa MK4 in issue 67 (hsmag.cc/67). FIND 3D PRINTS There’s an absolutely massive community of 3D printers sharing their files on the internet, and mostly for free! If you have an idea for a part or print in general, you should look on Thingiverse (thingiverse.com) or Printables (printables.com). We’ve also seen files on Etsy for sale of great items, so don’t forget to look around for prints. MAKE YOUR OWN…

MAKER Lucy Hattersley Lucy is editor of The MagPi magazine and enjoys computers and her cat. Overclocking the cat is probably a bad idea though. Probably? magpi.cc You’ll Need > Raspberry Pi 5 magpi.cc/raspberrypi5 > Raspberry Pi OS (Bookworm) magpi.cc/software > Active Cooler or Fan Case recommended magpi.cc/activecooler By default, Raspberry Pi 5 offers a huge speed increase over previous models. Having said that, more is always a bonus and it’s possible – if not always desirable, or necessary – to push the speed pedal a little harder. With some Raspberry Pi devices, you can make the clock speeds run even faster, a process known as “overclocking”. Overclocking Raspberry Pi 5 via Raspberry Pi OS isn’t dangerous, but it isn’t supported either (and not all Raspberry Pi 5 boards respond…

If you didn’t react fast enough, then it was quite easy to crash the robot. Adding an ultrasonic distance sensor means that the robot can automatically stop before colliding with a wall or other object. The sensor used is similar to those found in car parking sensors. The robot senses the distance to objects in front and automatically stops forward movement when an object is too close. With additional code, this…
