From the project
Collection of electronic circuits I designed, tested, and documented using KiCad
A beginner-friendly educational non-contact wire detector project using a copper sensing connection, three C945 transistor stages, and an LED indicator.
This project demonstrates a simple non-contact hidden wire detector concept. The KiCad schematic shows a sensing connection labeled copper, three C945 transistor stages, and an LED indicator.
The circuit is intended for electronics learning and supervised demonstration. It must not be connected directly to mains voltage, must not be treated as certified safety equipment, and must not be used as the only method to decide whether wiring is…
