6ElctrC is the final progression from 6ElctrA and 6ElctrB, giving students the opportunity to design and prototype an original audio‑electronics device of their choice. Working individually, students develop a complete project from proposal to prototype, integrating research, schematic design, component selection, and practical construction on protoboard.The project is student‑driven but supported through structured supervisory check‑ins, including a proposal presentation, two formative debrief sessions, and a final summative presentation. Throughout the process, students refine their design, respond to feedback, and demonstrate their ability to apply audio‑electronics principles to a real‑world circuit.The capstone concludes with a functional prototype, full schematics, and a written report documenting the research foundation, design process, measurements, and analysis. The module prepares learners to apply their technical skills independently and confidently within audio‑technology and electronics‑related fields.
