welcome to the magpi 113

I still remember picking up my first Raspberry Pi computer like it was yesterday. I built a small two-wheeled robot and got all the likes on Facebook. One thing led to another, and here I am editing this incredible magazine. Everybody has to start somewhere, and this month we’ve put together a Get Started with Raspberry Pi feature (page 30). This article helps newcomers put together a Raspberry Pi, install the Raspberry Pi OS operating system, and discover basic electronics with GPIO. It’s perfect for Raspberry Pi newbies. We’ve also got the best Starter Kits (page 82) and some great beginner-friendly tutorials. Whether it’s creating Pong controllers (page 40), building a binary clock (page 58), or using sensors to build your own Weather Station (page 50), there are some great ideas here…

old school minitel laptop

Prior to the development of the World Wide Web, France had a hugely popular telecommunications service called Minitel. It allowed the country’s citizens to book train tickets, check their electronic mail, search the telephone directory, and access online banking among other things, attracting an estimated 25 million users and offering around 26,000 services at its peak. Launched in 1982 and remaining in use for exactly 30 years, it was far ahead of its time. Anyone who wanted a terminal to connect to Minitel could get one for free from what became France Télécom, and this led to 9 million sets being installed in homes by 1999. But since Minitel closed, many have ended up being sold. “It’s easy to find a terminal on sale for below €10,” says French maker Gautier…

mini-guide to revitalising a minitel

01 The bulk of the electronics are behind the Minitel’s screen and need to be removed. A new screen is fixed using printed parts. STL files of these are provided by Gautier. 02 A Minitel contains a simple matrix keyboard. The matrix is constantly scanned, allowing it to detect when a key is pressed and a circuit is closed. It must be mapped. 03 Now the case can be kitted out with Raspberry Pi (in a 3D-printed case), a battery, a light indicator, and power supplies. Hot glue is used to affix the components.…

picolight

As active members of the open-source hardware community, Bucharest-based makers Alexandra Covor, Constantin Craciun, and Mihnea Stoica regularly post project tutorials for the wider community. Impressive images of their projects are essential in order to ignite interest. However, finding the right light to shine on their endeavours was becoming a challenge, so like all good makers, the team decided to make their own. PicoLight is the result – a Raspberry Pi Picobased, minimalist adjustable light which is perfect for low-light photography, as project lead Alexandra shares: “Studio lights are great, but they are often too big and too bright for our tiny [hardware] projects, so this is where PicoLight comes in, being ideally sized.” Small but mighty Alexandra describes PicoLight’s user experience as “pretty simple”. It’s made up of two fully customised PCBs…

big boxes

For communities affected by man-made or natural disasters, web access provides a critical lifeline. Not-for-profit organisation Jangala provides internet access for displaced people. The organisation was born out of its founders’ involvement in humanitarian relief efforts. These included the Amatrice earthquake in central Italy in 2016 and supporting refugees living in Camp de la Lande, Calais. Jangala’s ruggedised Big Boxes provide web access in challenging environments and, with a recent Raspberry Pi upgrade, are now capable of offering connectivity to multiple users via almost any wireless means. Their mission is to connect every school, clinic, and community resilience project worldwide. In 2019, the project won a Tech4Good Africa award, having supplied internet access to 50 students at a refugee camp in Kenya, enabling them to complete their diplomas. The Big Easy Jangala co-founder and…

virtual birthday cake

While some (us) might argue that the best part of a birthday cake is the cake itself, there’s definitely something to be said for an interactive model cake that does stuff in Minecraft. Also, there is a real cake underneath it all after you’ve finished with the virtual stuff. “The virtual cake consists of a looping video of a cake created on Minecraft with nine candles that can be blown out by spinning miniature wind turbines on a matching physical model cake,” Stephen Thompson, the creator of this cake, tells us. “Once all the candles are blown out, the birthday child can lift the model cake to reveal an edible cake which is mercifully free of children’s saliva.” Sounds a bit more tasty and clean when you put it that way. “I have…
