A 3-Phase Energy Meter with Multicore Support Using an ESP32 MCU with Voltage and Current Sensors
To continuously monitor energy consumption in his home, and store and communicate the data wirelessly, Gamal built a 3-phase energy meter, using a single ESP32 MCU with dual-core architecture, and voltage and current sensors. In his novel design, one core senses voltage and current and calculates consumed energy, while the other, long-forgotten core handles the user's web requests, logs measurements on an SD card, and displays current, voltage, and cumulative power consumption.

Adopting Test-Driven Development in Embedded Systems
Embedded software development has long been characterized by unique constraints such as limited resources, strict real-time requirements, and complex interactions with hardware. As a result, traditional software development methodologies often fail to translate smoothly into the embedded space. However, modern embedded development is evolving, and techniques like Test-Driven Development (TDD) are no longer just for web and enterprise applications: they're essential for building reliable and maintainable embedded systems.
