Step-by-step tutorials on embedded systems, SBCs, Raspberry Pi, Arduino, and IoT. Practical guides for engineers, students, and makers.
The Raspberry Pi CM0 is designed as an ultra-compact, low-power compute module targeting makers and embedded developers in the Chinese market. Its stamp-hole (castellated) form factor allows seamless integration into custom carrier boards, making it ideal for DIY hardware projects, AIoT edge devices, and minimalist smart gadgets. Compared with compute modules that rely on industrial […]
This open-source smartwatch project is built around the ESP32-S3 platform and provides a complete hardware–software development workflow, including schematic design, PCB layout, firmware development, and system debugging. The watch integrates wireless communication, environmental sensing, motion detection, distance measurement, and customizable user interaction, making it suitable for a wide range of engineering applications such as IoT
The Nintendo WaveBird wireless controller—released in 2002—was widely regarded as the gold standard for untethered gameplay in the GameCube era. Using a proprietary 2.4 GHz RF system rather than infrared, it offered an official range of 6 m and real-world performance exceeding 20 m, with up to 100 hours of playtime from two AA batteries.
Thermal imaging no longer has to rely on high-end, expensive equipment. With an ESP32 and an affordable infrared sensor, hobbyists and engineers can build a compact thermal camera capable of visualizing temperature patterns, identifying hotspots, and troubleshooting thermal issues in everyday applications. Thermal imaging is invaluable in industrial inspection, electronics debugging, outdoor navigation, and safety
