This year marked the 10th anniversary of Coolest Projects Belgium. The meticulously organised event was held in April by our partner CoderDojo Belgium, at Technopolis in Mechelen. Themed ‘On the move’, the event invited young creators to interpret movement however they liked – which they did in an impressive number of ways, creating projects ranging from mobile robots and Scratch animations to AI tools, health tech devices, and a musical drink maker.

With 52 inspiring creations showcased by 71 young people, there were too many awesome projects to list individually in this blog post. Here are just a few of our highlights from a day filled with big ideas and brilliant builds.

Rune | IINTS (Insulin Is Not the Solution)

Rune, who has type 1 diabetes, built his own open-source insulin pump powered by Raspberry Pi Pico W and featuring a custom motor-controlled delivery system designed in Autodesk Fusion. Rune’s pump calculates insulin doses based on carbohydrate amounts entered – all with the goal of empowering people, raising awareness, and making medical technology more accessible.

Amir | AmirAI 

Amir might only be 10, but he is already experimenting with chatbots and AI in creative and playful ways. His self-coded AI assistant could respond live to visitors’ prompts, producing jokes and answers to questions. Amir’s project was a great demonstration of how accessible complex technologies can be when you give young people space to explore them.

Jules | Operatie Mocktail

This Arduino-powered machine blends mocktails based on your music choices. Pick a song, and the machine mixes a custom drink to match the song’s mood. It is a joyful combination of engineering, flavour science, and artistic flair. Jules described it best: “I want to create a unique drinking experience that connects taste and music in a surprising way.” We think it’s just right!

Mona | On the Move

Mona’s project is a reimagination of Michael Rosen’s poem On the Move created in Scratch, featuring animation, sound, and voice-over. It is a wonderful example of how digital storytelling can give new life to spoken word, and how creative coding platforms like Scratch provide space for emotion and expression.

Digital making: more than just a skill

Beyond these projects, the showcase included creations such as autonomous robots, arcade games, imaginative interface devices, and even a computer-controlled magic wand factory made of Lego bricks. Whether it was a creator’s very first Scratch project or a hand-built automaton, the range of work on display showed that coding and digital making are not just skills – they’re tools for self-expression, exploration, and change.

We would like to say a massive thank you to CoderDojo Belgium for hosting such an incredible event, and to the young creators, families, volunteers, and judges who made it such a success.

We are already looking forward to seeing what participants will create next!
