Experience AI with the Raspberry Pi Foundation and DeepMind

via Raspberry Pi

I am delighted to announce a new collaboration between the Raspberry Pi Foundation and a leading AI company, DeepMind, to inspire the next generation of AI leaders.

Young people work together to investigate computer hardware.

The Raspberry Pi Foundation’s mission is to enable young people to realise their full potential through the power of computing and digital technologies. Our vision is that every young person — whatever their background — should have the opportunity to learn how to create and solve problems with computers.

With the rapid advances in artificial intelligence — from machine learning and robotics, to computer vision and natural language processing — it’s increasingly important that young people understand how AI is affecting their lives now and the role that it can play in their future.

Experience AI is a new collaboration between the Raspberry Pi Foundation and DeepMind that aims to help young people understand how AI works and how it is changing the world. We want to inspire young people about the careers in AI and help them understand how to access those opportunities, including through their subject choices. 

Experience AI 

More than anything, we want to make AI relevant and accessible to young people from all backgrounds, and to make sure that we engage young people from backgrounds that are underrepresented in AI careers. 

The program has two strands: Inspire and Experiment. 

Inspire: To engage and inspire students about AI and its impact on the world, we are developing a set of free learning resources and materials including lesson plans, assembly packs, videos, and webinars, alongside training and support for educators. This will include an introduction to the technologies that enable AI; how AI models are trained; how to frame problems for AI to solve; the societal and ethical implications of AI; and career opportunities. All of this will be designed around real-world and relatable applications of AI, engaging a wide range of diverse interests and useful to teachers from different subjects.

Experiment: Building on the excitement generated through Inspire, we are also designing an AI challenge that will support young people to experiment with AI technologies and explore how these can be used to solve real-world problems. This will provide an opportunity for students to get hands-on with technology and data, along with support for educators. 

Our initial focus is learners aged 11 to 14 in the UK. We are working with teachers, students, and DeepMind engineers to ensure that the materials and learning experiences are engaging and accessible to all, and that they reflect the latest AI technologies and their application.

As with all of our work, we want to be research-led and the Raspberry Pi Foundation research team has been working over the past year to understand the latest research on what works in AI education.

Next steps 

Development of the Inspire learning materials is underway now, and we will release the whole set of resources early in 2023. Throughout 2023, we will design and pilot the Experiment challenge.

If you want to stay up to date with Experience AI, or if you’d like to be involved in testing the materials, fill in this form to register your interest.

App note: Small, simple, PWM buck controller can replace high current LDOs

Low dropout, linear regulators, or LDOs, are typically used for post−regulation because they are easily implemented and provide a relatively noise−free power source. However, for higher currents, such as 1.0 A and above, LDOs take up a great deal of space and can dissipate too much power and thus heat. For low dropout applications where you need another voltage rail, and you already have a 5.0 V or 3.3 V rail, a simple PWM buck converter provides a more efficient choice than a linear regulator.

Astro Pi Mission Zero 2022/23 is open for young people

via Raspberry Pi

Inspire young people about coding and space science with Astro Pi Mission Zero. Mission Zero offers young people the chance to write code that will run in space! It opens for participants today.

A young person takes part in Astro Pi Mission Zero.

What is Mission Zero?

In Mission Zero, young people write a simple computer program to run on an Astro Pi computer on board the International Space Station (ISS).

Participation is free and open for young people up to age 19 in ESA Member States (eligibility details). Everything can be done in a web browser, on any computer with internet access. No special hardware or prior coding skills are needed.

Participants will receive a piece of space science history to keep: a personalised certificate they can download, which shows their Mission Zero program’s exact start and end time, and the position of the ISS when their program ran.

All young people’s entries that meet the eligibility criteria and follow the official Mission Zero guidelines will have their program run in space for up to 30 seconds.

Mission Zero 2022/23 is open until 17 March 2023.

New this year for Mission Zero participants

If you’ve been involved in Mission Zero before, you will notice lots of things have changed. This year’s Mission Zero participants will be the first to use our brand-new online code editor, a tool that makes it super easy to write their program using the Python language.

Thanks to the new Astro Pi computers that we sent to the ISS in 2021, there’s a brand-new colour and luminosity sensor, which has never been available to Mission Zero programmers before:

Finally, this year we’re challenging coders to create a colourful image to show on the Astro Pi’s LED display, and to use the data from the colour sensor to determine the image’s background colour.

The theme to inspire images for Mission Zero 2022/23 is ‘flora and fauna’. The images participants design can represent any aspect of this theme, such as flowers, trees, animals, or insects. Young people could even choose to program a series of images to show a short animation during the 30 seconds their program will run.

Here are some examples of images created by last year’s Mission Zero participants. What will you create?
