Welcome to luigi-hw, a curated GitHub organization dedicated to hardware, embedded systems, and electronics projects developed and maintained by Luigi C. Filho.

This organization serves as a hardware engineering portfolio, showcasing design experiments, embedded systems, and practical electronics projects with a strong engineering mindset.

The goals of luigi-hw are to:

• Showcase hardware and embedded systems projects
• Demonstrate engineering fundamentals and design trade-offs
• Explore interactions between hardware and software
• Document experiments, prototypes, and learning processes
• Serve as a technical portfolio for hardware, embedded, and IoT-related roles

Projects here are intentionally selected and documented to reflect engineering reasoning, not just final results.

Projects in this organization may involve:

• Embedded systems and microcontrollers
• Digital and analog electronics
• Hardware prototyping and experimentation
• Firmware development
• Hardware–software integration
• System-level thinking and trade-off analysis

Whenever applicable, repositories may include:

• Schematics and diagrams
• Bill of Materials (BOM)
• Firmware source code
• Setup instructions and notes
• Design decisions and limitations

Common technologies and tools used across projects include:

• Microcontrollers: PIC, Arduino, ESP32, STM32
• Programming Languages: Assembly, Embedded C
• Hardware Description Languages: Verilog, VHDL
• Electronics: Sensors, actuators, power regulation
• Design Tools: CAD, schematic capture, datasheets
• Debugging: Logic analyzers, serial debug, oscilloscopes

Some repositories in this organization explore experimental ideas and prototypes created for learning, validation, or curiosity-driven engineering.

These projects:

• Are not necessarily production-ready
• Do not aim to replace certified or industrial solutions
• Exist to deepen understanding of hardware behavior, constraints, and system interactions

This distinction is intentional and reflects responsible engineering practice.
