Previous PA Raspberry Pi Competition award winners

Our annual PA Raspberry Pi Competition promotes STEM education by challenging schoolchildren to invent systems that could benefit society using their engineering and coding skills. 

Here's a look back at the ingenious projects that have won the competition in past years. 

2022: Innovations to save the planet

For our tenth anniversary, we put the year's theme to a public vote, asking teachers, students and our partners what they think would be most inspiring. And they chose: innovations to save the planet.

As the UN shares a bleak outlook on climate change, the need to act quickly on sustainability has never been more apparent. So, for the 2022 PA Raspberry Pi Competition, we challenged 8- to 18-year-olds to design technology that would help make the world a more sustainable place.

The winners of 2022's competition were:

Years 4-6: Raspberry Turtles from King Edward’s Junior School, Bath
Recycling stations which help to inform, educate and raise awareness about environmental issues
Years 7-9: Project Polar Bear from Belhaven Hill School, Dunbar
An automatic bin opener that sorts different rubbish using AI
Years 10-11: The E-consumer team from Richard Hale School, Hertford
A project to reduce the volume of greenhouse gases released into our atmosphere every year by the transportation of food
Years 12-13: Team Tera from King Edward VI Grammar School, Chelmsford

2021: Creating a positive human future for everyone

For the ninth competition, we challenged 8- to 18-year-olds to design technology to help create a positive future for everyone as we come out of an unprecedented period of uncertainty.

COVID-19 has been a once-in-a-generation challenge, but we’ve seen inspiring examples of where it’s catalysed the best of humanity and unlocked our inherent ingenuity. So, we asked the teams to imagine a world where we can:

  • Develop a cleaner, most sustainable world
  • Be better prepared for the unexpected
  • Interact safely and effectively, whether at work, study or leisure
  • Support the health and wellbeing of everyone
  • Get urgent supplies into the hands of those who need them most.

The winners of 2021's competition were:

Years 4-6: St Mary's CE Primary School
An intelligent cane that communicates with other devices to inform blind, partially sighted or deaf-blind people of nearby hazards
Years 7-9: Priestnall School
