Cheng-En, Ko-Hsin and Zi Qing realised that rapid climate change was contributing to rising water levels, putting birds who previously relied on the river for their habitats in danger. Using the micro:bit, the ‘Best birds guardian’ senses rising water and pulls the birds' nest to safety on the river shore.
Jingyu Xiao liked seeing plant walls in his city but wanted to protect them from the frequent typhoons that hit. He created a smart living wall that could automatically retract and extend according to the weather forecast. He also added a soil moisture sensor to ensure the plant wall was appropriately watered.
Theo, Harry, and Timofei wanted to create an efficient and affordable solar panel to make reusable energy more appealing. Using the micro:bits light sensors and servos, their solar panel moves to always face the sun, improving productivity and efficiency.
Arieh and Samuel built a prototype to work towards achieving Global Goal 13: Climate Action. Together they created a 3D printed solar-powered electric boat. They created 2 prototypes and tested them on the water before choosing the most effective elements of each one for their final design.
Mustafa and Mand created the ‘Angry Tree’, a device that monitors trees and alerts humans to issues such as dry soil, high heat, and attempted tree felling. They recognised the importance of trees in the battle against climate change and created a complex solution to the problem of tree destruction.
Clara built the innovative ‘Hermes’ shoe that charges your phone as you walk. The shoe encourages people to exercise and increase their step count by charging their phone at the same time - improving mental health and generating renewable energy!
Kenna and Margot created a portable filtration device, dedicated to achieving Global Goal 6: clean water and sanitation. In their creation, a micro:bit controls UV LEDs that work to sterilize drinking water. The device is also solar-powered - making it affordable and portable.
8-14 year olds, paper prototypes
In this category, we asked young people to create a paper prototype to explain their idea.
Rajunor, Theophania and Jinelle thought up a solution to alert people to environmental changes that could cause asthma attacks. The team discovered that asthma patients suffered more in cloudy seasons and so came up with the idea that uses a temperature sensor and alert system to solve the problem.
Asia and Pacific
Indiana wanted to help her family members who struggled with severe anxiety. She created ‘Total Relax: Massage box’, a wearable solution that measures your heart rate and reminds you to relax.
Brodie, Charley and Zoey created a paper prototype for ‘The Healthy micro:bit’. This device reminds you to go outside for some fresh air and vitamin D every 90 mins. The solution records how long you have been outside and suggests activities you could take part in.
Emily, Melanie and Valentina created a huge model to illustrate how their idea, a safe environment for bees, would work. The device measures temperature and humidity and counts the number of bees visiting.
Jana drew plans for a reusable, virtual facemask. Our do your :bit judges were impressed with the amazing creativity and innovative thinking Jana brought to her entry to solve the very real problem of disposable mask waste.
Zong was inspired by the tentacles on an octopus to create his paper prototype for a soft drain cleaner. A micro:bit would control four motors that can delicately move around intricate spaces. The device was designed for cleaning drains but Zong thought it could also be used for medical surgery.
15-18 year olds, micro:bit solution
15-18 year olds were challenged to design and make a solution using the micro:bit.
Ghassen created an innovative solution that uses braille to allow visually impaired people to share text messages. The do your :bit judges were impressed with the well-constructed prototype and solution for people who would not be able to participate in an activity that many of us take for granted.
Asia and Pacific
Ahmad, Mifzal and Muhammad invented an ‘Oxygen Percentage Analyser’ to detect deforestation in a more efficient way than using satellite images. The creation uses two micro:bits - one placed in the forest, and one with the forest ranger who will be able to constantly monitor the oxygen levels of the forest.
Aoife and Emma built a micro:bit creation to encourage physical activity and limit screentime. ‘Exercise is the key’, which makes use of the micro:bit accelerometer rewards physical activity with 15 minutes of screentime. The girls identified that using the micro:bit allowed them to make their creation small, and therefore more practical for the user.
Sebastian wanted to create something to help people stay healthy and hydrated. The ‘Smart water bottle’ uses micro:bits for two functions - one to measure the intensity of the sunlight and remind you to shelter and stay hydrated, the other checks the water level in your bottle and reminds you to take a sip.
Mahmoud and Yasmina worked together to create ‘G.A.N.T - Gas and Noise Trapper’. The device protects people from noise and air pollution. G.A.N.T uses sound and gas sensors attached to the micro:bit to measure smoke and noise levels. If it detects dangerous levels the micro:bit triggers a servo to shut the window.
Ali devised a large-scale automatic tree farm that uses a network of micro:bits to control and maintain the trees’ growth. He envisaged that the farm could be used to grow trees to replace those lost in bushfires.
Alicia and Esmée created ‘Micro:Calm’, an all-in-one micro:bit device that provides users with multiple coping mechanisms to deal with anxiety. This included a fidget toy, emotion check-in, box breathing and a game. The girls hoped this could be used by people of any age and work towards achieving Global Goal 3 - Good health and well-being.
