Several motorized sliders usually mean extra drivers, feedback wiring, and GPIO use. FaderBuddy puts that work on a modular board for 60 mm faders, with an ATtiny1616 handling motion locally. One I2C bus can serve multiple boards, while ESPHome connects the controls to Home Assistant with a little YAML.

One inexpensive ESP32 Cheap Yellow Display can become a music dashboard, F1 notifier, game system, video player, graphics demo, or 3D-printer panel. This community directory gathers links and flashing tools in one place, while reminding readers to check each project’s parts, documentation, wiring, and installation steps first.

Thermocouple feedback and PID control give this ESP32 hot-air station a measured way to heat surface-mount parts. Its custom PCB, MicroPython firmware, and programmable airflow make it more than a loose collection of modules, while the high-temperature hardware demands careful insulation, grounding, cooling, and power handling.

OOMWOO treats a robot vacuum as a complete maker-built system: 3D-printed parts, LiDAR, Raspberry Pi computing, microcontrollers, ROS2, and Home Assistant work together without required cloud services. It remains an early-development project, though, with full build instructions planned for Fall 2026 rather than a ready-made weekend kit.

A Raspberry Pi, RetroPie, custom controls, and a 3D-printed case become a portable game console in this detailed build. The guide covers setup, GPIO wiring, screen mounting, battery power, assembly, and testing, while honestly describing the soldering, programming, fitting, and troubleshooting skills the project demands.
