Watch Elektor Lab Talk #38

Elektor has released a new episode of its popular Lab Talk series, offering engineers, makers, and students an inside look at innovative wireless projects, behind-the-scenes lab developments, and upcoming opportunities to sharpen technical skills. In Lab Talk #38, Elektor editor Brian Tristam Williams is joined by Senior Engineer Saad Imtiaz and guest Sebastian from Baltic Lab, a specialist in RF and wireless design. Together, they explore the latest in community-driven innovation while highlighting trends shaping the future of electronics.
 

The episode includes with a roundup of standout wireless and IoT projects from the Elektor Labs community. Highlights include a low-noise dual-channel linear power supply designed for analog testing, an RTTY weather receiver that blends vintage radio concepts with modern ESP32 decoding, and a wireless scales project using load sensors and ESP32 modules to calculate weight across multiple points. Each example demonstrates how today’s makers are pushing boundaries with accessible microcontrollers and creative problem-solving.

Beyond community contributions, the Elektor team shares updates from their own labs. Saad presents a newly designed LoRaWAN Sense Node PCB, an all-in-one board featuring GPS, ESP32, solar charging, and ultra-low-power timers for long-term IoT sensing. He also walks viewers through his experiments with an ESP32-based energy meter paired with Edge Impulse machine learning to detect household appliance usage—an ambitious project that reveals both the promise and challenges of AI at the edge, particularly when working with unbalanced datasets.

Guest engineer Sebastian adds depth to the discussion by focusing on electromagnetic compatibility (EMC). Drawing on his expertise in wireless systems, he explains how switch-mode power supplies create RF interference, why inductor orientation matters, and how hobbyists can begin tackling EMC issues with accessible tools like near-field probes and entry-level spectrum analyzers. His insights highlight the growing overlap between power electronics and RF engineering, an area increasingly relevant for IoT and embedded developers.

The session also shines a spotlight on new products and training resources. Williams presents the just-launched Raspberry Pi 500+, which is positioned as the most advanced Pi yet. 

Rounding out the episode are magazine updates, including the September Wireless & Communication edition of Elektor Magazine and a digital bonus issue packed with additional projects. As always, the Lab Talk concludes with a live Q&A and a giveaway.

With its mix of practical engineering advice, project showcases, and industry insights, Lab Talk #38 delivers real value for anyone working in wireless, IoT, or embedded systems. Whether you’re an experienced engineer or a curious maker, this episode offers both technical takeaways and inspiration for your next build.
