Each week explores a new domain of digital fabrication and embedded design.

Capstone Work

LoRa Walkie‑Talkie System

A LoRa-based walkie-talkie system designed to control multiple nodes remotely using an ESP32-based Heltec module. The main controller switches communication frequencies to target specific nodes, sending commands that trigger pre-recorded audio messages stored on SD cards.

Each node includes an ESP32, speaker, and control buttons — allowing it to play received messages or respond when prompted. The system leverages LoRa's long-range communication for reliable, low-power operation.

François Dei

Electronics and Telecommunications graduate with strong experience in embedded systems and digital fabrication — over four years of hands-on practice building IoT and hardware solutions for developing communities.

Professional certificate from FabLab Rwanda in Embedded Systems and Hardware with Digital Fabrication. Projects span agriculture, energy, and smart monitoring — always focused on practical problem-solving and technology for social impact.

Engaged in robotics and STEM education through EdTech — building educational robotics kits aligned with Rwanda's national curriculum and training schools across the country.

Research · Mining
Smart Mining Helmet
Curiosity about monitoring life and providing communication under mining tunnels led to this innovation — accessed the Open Skies Fellowship.
Research · Wearables
UNPOD — Smart Jacket
Extended research from the helmet concept into a smart jacket system — winner of the UNPOD competition.
