Reading Time: 2 minutesROS (Robotic Operating System) is the OS installed on Raspberry Pi for Mini Pupper, and Mini Pupper includes OpenCV, SLAM (Simultaneous Localization and Mapping), and other navigation technologies. It will create a map of an area, much like a Roomba so that it can navigate it better. Pupper in the window Our Mini Pupper came […]
Reading Time: 3 minutesOld timer “We bought a railway station clock from a flea market and were a bit crestfallen when nothing happened when we plugged it in,” explains Martin. “The nice man who sold it seemed adamant that it worked, so after a bit of reading, I found out that it was waiting for a signal from […]
Reading Time: 3 minutesSuper Simple Robotics Rolling a wheeled robot around with code is a cool thing to do with Raspberry Pi. Turning a jumble of wires and wheels into a controllable critter is much easier than you’d imagine. This month’s cover feature explains how motors, servos, and sensors all work together. Plus we look at some of […]

Reading Time: 3 minutesWhile Emilio says he’s in good health, he feels his sleep quality has degraded over the years: “I have been trying to understand why and what could I do to improve it. There is nothing better than waking up in the morning feeling fully recovered and energised!” Bedroom eyes The concept for the tracker came […]
Reading Time: 3 minutesLooking at Dan Beimborn’s Mac SE/30, you’d think it was worth the outlay. Photographs suggest it’s running fine 33 years on, but that’s not actually true in this case. Instead, this model has been stripped of all its innards and it is running entirely on a Raspberry Pi 4 computer. “I thought it would be […]
Reading Time: 3 minutesThe hardware from which SpiderPi is constructed is similar to that of its Hiwonder sibling, TonyPi, reviewed back in The MagPi 111 (magpi.cc/111). Controlled by a 4GB Raspberry Pi 4, SpiderPi’s legs are made from 18 servos – three for each of its six legs – fitted into hinged aluminium frames, giving it a Meccano-like […]
Reading Time: 3 minutes “As a kid during the 1980s, I was a big fan of Knight Rider and I remember watching it thinking KITT was the coolest car ever,” says Fred Arias. “I even remember going to Universal Studios in Hollywood, where I got the opportunity to sit inside KITT and talk to him directly. That experience […]
Reading Time: 3 minutesWith that in mind, he got to work on a device that could calculate the sun’s position based on a person’s longitude and latitude. Aside from showing the angle of the sun relative to where the viewer is on Earth, he wanted it to show the position of the Earth in relation to the star, […]
Reading Time: 2 minutesA pair of reset pins are linked to a handy reset button on the top, where there’s also a boot button – held to attach the board as a USB drive to a computer – and a programmable button linked to GPIO pin 20. Other connections include a micro-USB port (for power and connecting a […]
Reading Time: 3 minutes“Super Make Something is a YouTube channel that aims to teach people about 3D printing, electronics, robotics, and other STEM topics through step-by-step DIY project videos,” Alex explains. “The source code and design files for all of my projects are always released for free alongside my videos, and while it is always cool to see […]
Reading Time: 3 minutes“Chris Croft, a friend of over 40 years is not only the world’s most watched project management trainer, but plays saxophone in a band (lost-at-sea.co.uk) for fun,” Keith explains. “He had someone design a light for his saxophone to illuminate it based on the note he was playing. It’s a great piece of electronics, but […]
Reading Time: 2 minutesYou’ll also need to flash Pico with Pimoroni’s custom MicroPython UF2 firmware. This includes the MicroPython module for the Pico Unicorn, which you can import at the top of your programs. While not as sophisticated as the Python one for Pimoroni’s Unicorn HATs for Raspberry Pi computers, it does enable you to set individual pixels […]
Reading Time: 4 minutes“The telescope is designed to achieve the highest sensitivity for wide sky observation, with a continuous high rotation speed of 120°/s to suppress atmospheric fluctuations,” explains Mike Peel, part of a team of astronomers from Japan, Korea, Spain, and The Netherlands who developed and work on the GroundBIRD project. Achieving precise observations with the telescope […]
Reading Time: 2 minutesRaspberry Pi Pico W Pico W brings a whole new element to Raspberry Pi’s RP2040 development platform. Our in-depth feature covers the specifications in detail, and shows you how to set up Raspberry Pi Pico W with the new firmware, and connect to your local network. Plus we chat to the hardware and software engineers […]

Reading Time: 2 minutesOther features include a standard micro-USB port (for 5 V power or connecting to a computer), two tiny push-buttons (including a handy reset), an on-board status LED, and six debug pins. Plug and play? That standard 40-pin GPIO header means you can connect any standard Raspberry Pi HAT, pHAT, or other compatible add-on board. The downside […]
Reading Time: 3 minutesToy camera The Raspberry Pi High Quality Camera can be used with the CS mount and lenses, but it’s not the only option. As maker Volzo explains, S-mount lenses (ideal for machine vision and infra-red photography) can also be used, which is what he chose for this Raspberry Pi Zero build designed to add zany […]
Reading Time: 2 minutesThen there’s a host of input and output options, including three analogue inputs (connected to Pico’s ADC channels) for connecting external sensors, a ZIP socket to add more LEDs, a three-pin servo connector, and two high-power outputs (screw terminals) with a max draw of 1 A. In addition, there are solder pads for 3V3 power, GND, […]
Reading Time: 2 minutesIt’s built like a regular home weather station, with sensors that can track local conditions. Combining those with the ozone concentration and online data in the training model adds that extra sauce to the project. Arduino and Raspberry Pi Data is fed to Raspberry Pi from an Arduino Nano 33 BLE for analysis.“I decided to […]
Reading Time: 3 minutesAnyone now wanting to get their hands on a Vectrex will find themselves hugely challenged, because this unique games system is extremely rare.
