The Smart-Fault-Detector is a specialized diagnostic device engineered to detect actuator faults and failures in high-stakes systems like rockets and robotics. By monitoring the "pulse" of an actuator through electrical and mechanical sensors, it identifies anomalies before they lead to catastrophic system failure.
The system is built around the GLYPH-C3 (ESP32-C3) microcontroller. The architecture is divided into modular blocks for power management, sensing, and user interface.

| Feature | Implementation | Purpose |
|---|---|---|
| Voltage | Opto-isolated (PC817) Divider | Safely measures high-voltage rails up to 12V with optical isolation. |
| Current | Copper Trace Shunt | Cost-effective and efficient current measurement via voltage drop. |
| RPM | IR Sensor | Non-contact measurement of rotational speed. |
| Vibration | Piezoelectric Sensor | Monitors mechanical impacts and high-frequency wear. |
The Smart-Fault-Detector ensures data is never lost, whether you are monitoring it live or analyzing it after a flight. Preview
