The latest episode of our monthly Lab Talk is here! If you missed it live, check it out below. As usual, we discuss upcoming articles, current projects and interesting topics we came across. If you’re into microcontrollers, audio processing, Raspberry Pi, or if you’re curious about getting started with FPGAs, there's something for everyone.
Our Senior Engineer Saad Imtiaz shares updates on his ESP32 energy meter, now compatible with MQTT and Arduino IDE, offering alternatives for data handling. I also took the opportunity to say a few words about a very simple, beginner-level FPGA project, where I made a clock in VHDL on a DE10-Lite board from Terasic, with help from ChatGPT for code generation—a real-world example of AI-assisted design. We also discuss an interesting audio project, the DSP FX Processor board from Clemens Valens. It combines an ESP32 and ADAU1701 DSP chip, supporting real-time audio effects for custom sound synthesis and filtering. This makes it a very nice project for audio enthusiasts interested in high-performance, programmable sound processing!
Brian shares insights from the recent Raspberry Pi event, featuring the new Raspberry Pi touch display, AI hat with a Hailo AI accelerator, a USB3 hub and more. Saad also talks about his AI-based security system using a Raspberry Pi to process CCTV streams, with real-time alerts via Telegram and improved thermal management. Then I mention a few ongoing product reviews that I’m currently preparing. Finally, you’ll hear a few details on Elektor’s plans for Electronica 2024! Watch the episode below:
