Year 13’s Muhammad Shah has won The Big Bang UK Young Technologist of the Year title for 2025.
His winning project, Icarus, is a decentralised telecommunication system designed for low-cost and effective emergency communications in remote areas: it was inspired by his love of the outdoors and of trekking.
Muhammad was one of 11 QE pupils to reach the finals of The Big Bang Competition.
Mark Wood, Social Sustainability Lead at sponsor Siemens GB&I, said: “Muhammad stood out with his decentralised communication system, which avoids reliance on cellular or satellite networks and has great opportunities for search and rescue, leisure and other business uses.
“Muhammad demonstrated independent learning and great communication and presentation skills and is a worthy winner of the prize!”
The Big Bang Competition, run by the EngineeringUK charity, is open to young people in the UK aged 11-18 who are in state-funded education, are home-educated or who enter as part of a community group.
The Big Bang UK Young Technologist of the Year award recognises innovation in digital and sustainable technology. It highlights the importance of technology in various sectors, including search and rescue, leisure, and business.
Muhammad describes himself as an aspiring engineer who enjoys 3D printing, CAD modelling, printed circuit board (PCB) design and other electronics.
His project was inspired by the communication difficulties people experience in remote areas, and particularly by the need for better communication when people out trekking get into difficulty. Its decentralised approach avoids reliance on cellular or satellite networks.
With Muhammad unable to attend the Big Bang Fair at Birmingham’s NEC because of an A-level examination, the prize was instead presented at the School’s Technology Design Showcase by EngineeringUK’s Director of Communications, Beth Elgood, and Siemens’ General Manager and UK Country Lead, Hannah Winstanley. The two also agreed to serve on the judging panel at the QE event.
Tech spec: how Muhammad solved the problem
Icarus uses a custom Meshtastic PCB based on ESP32-S3 N8R8, L76K GPS and LoRa RA-01SH, designed to be fully assembled by the online PCB service provider, JLCPCB.
Meshtastic is a decentralised, off-grid network that lets users send and receive messages using affordable, low-power devices. Icarus also makes use of LoRa, a long-range radio protocol, which is widely accessible in most regions without the need for additional licences or certifications (unlike HAM radio). These radios are designed to rebroadcast messages they receive, forming a network. This setup ensures that every group member, including those at the furthest distance, can receive messages.
				
									
The one-day event gave pupils the chance to hear from leading doctors across a range of specialisms – several of whom are involved in medical research – and to talk to current medical students.
“This was achieved through a series of insightful talks delivered by some of the most inspiring doctors and medical students we could have asked for, followed by a vibrant networking session in our atrium.”

Soham added: “Organising and hosting this event was a huge learning experience. From coordinating speakers and logistics to dealing with last-moment changes under pressure, it has pushed me to grow as both a team-player and a communicator. It also reaffirmed my passion for Medicine – not just as a career, but as a field built on human connection and constant learning.”
									
Although entrants compete as individuals, they are placed in national teams. Harik was part of a five-strong UK team, all of whom won medals. Three took bronze, while one was another silver winner, albeit with a lower score and ranking than Harik’s. Medals were awarded to the top 208 competitors.
									
									
									
The four, who were competing against 71 other teams, took second place overall in the final, held at the Royal Horticultural Halls in central London.
The event consisted of five demanding rounds: the Group Circus, Shuttle, Crossnumber, Relay, and Poster rounds. The rounds are designed to test mathematical thinking, teamwork and resilience.
