    Celebrating 10 years of Raspberry Pi with a new museum exhibition

    Reading Time: 2 minutes

    Ten years ago, Raspberry Pi started shipping its first computers in order to inspire young people to reimagine the role of technology in their lives. What started with a low-cost, high-performance computer has grown into a movement of millions of people of all ages and backgrounds.

    A group of children and an adult have fun using Raspberry Pi hardware.

    Today, Raspberry Pi is the UK’s best-selling computer, and the Raspberry Pi Foundation is one of the world’s leading educational non-profits. Raspberry Pi computers make technology accessible to people and businesses all over the world. They are used everywhere from homes and schools to factories, offices, and shops.

    Visit the history of Raspberry Pi

    To help celebrate this 10-year milestone, we’ve partnered with The National Museum of Computing, located at the historic Bletchley Park, to open a new temporary exhibit dedicated to telling the story of the Raspberry Pi computer, the Raspberry Pi Foundation, and the global community of innovators, learners, and educators we’re a part of.

    In the exhibit, you’ll be able to get hands-on with Raspberry Pi computers, hear the story of how Raspberry Pi came to be, and see a few of the many ways that Raspberry Pi has made an impact on the world.

    Join us for the exhibition opening

    We know that not everyone will be able to experience the exhibit in person, and so we’ll live-stream the grand opening this Saturday 5 March 2022 at 11:15am GMT. Keep an eye on our social media channels for the link to watch the video feed. If you’re able to make it to the National Museum of Computing on Saturday, tickets are available to purchase.

    We’re delighted to celebrate 10 years with all of you, and we’re excited about the next 10 years of Raspberry Pi.

  • Remote teams ring office bell with Raspberry Pi and Slack

    Remote teams ring office bell with Raspberry Pi and Slack

    Reading Time: 3 minutes

    Bustling offices… remember those? It feels like we’ve all been working from home forever, and it’s going to be a while yet before everyone is back at their desks in the same place. And when that does happen, if your workplace is anything like Raspberry Pi Towers, there will still be lots of people in your team who are based in different countries or have always worked from home.

    This office bell, built by a person called Alex, is powered by a Raspberry Pi 3B+ and is linked to Slack, so when a milestone or achievement is announced on the chat platform by a remote team member, they get to experience ringing the office bell for themselves, no matter where in the world they are working from.

    Kit list:

    Integrating with Slack

    To get the Raspberry Pi talking to Slack, Alex used the slackclient module (Python 3.6+ only), which makes use of the Slack Real Time Messaging (RTM) API. This is a websocket-based API that allows you to receive events from Slack in real time and send messages as users.

    With the Slack RTM API, you create an RTM client and register a callback function that the client executes every time a specific Slack event occurs. When staff tell the @pibot on Slack it’s ‘belltime’, the Raspberry Pi tells the servo to ring the bell in the office.

    Alex also configured it to always respond with an emoji reaction when someone successfully rings the bell, so remote employees get some actual feedback that it worked. Here’s the script for that bit.

    Alex also figured out how to get around WiFi connectivity drops: they created a cronjob that runs a bash script every 15 minutes to check if the bell ringer is running. If it isn’t running, the bash script starts it.

    At the end of Alex’s original post, they’ve concluded that using a HAT would allow for more control of the servo and avoid frying the Raspberry Pi. They also cleaned up their set-up recently and switched the Raspberry Pi 3B+ out for a Raspberry Pi Zero, which is perfectly capable of this simple job.
