IEEE UCT is excited to launch the IEEE STEM HARVEST Challenge⚡️!
🎯 What’s the Challenge?
A LEctenna uses a Schottky diode connected to an LED to convert and visualize harvested electromagnetic energy from a mobile phone’s Wi-Fi antenna.
• Record: 14 LEDs lit simultaneously
• Your Goal: Light at least 14 LEDs simultaneously using a mobile phone!
🏆 Prizes & Showcase:
• Cash Prizes: Total pool of ~6,000 ZAR for top 3 teams.
• IEEE RADIO 2026: First 3 teams to light >14 LEDs get invited to present live at IEEE RADIO 2026 (Oct 26–29)!

Starter Kits & Rules:
• Free Kit: 10 Schottky diodes + 10 Red LEDs per registered team.
• Custom Tuning: Feel free to use extra *passive* components like capacitors, inductors, or diodes to boost power and improve your design.
• Extra Stock: More diodes/LEDs available upon request. 🗓️
