Electronics Unit
AssemblyThe shaft-mounted module that generates transmit pulses, amplifies and samples the receive signal, and runs the detection and ground-compensation algorithms. A full specification article for this item is being written. Meanwhile its bill of materials and connections are below.
Electronics Unit parts and their functions
6 top-level parts · 289 parts in total · full bill of materials below
| # | Part | Qty | What it does |
|---|---|---|---|
| 1 | Pulse Driver 3 parts | 1× | Power stage that switches several amperes through the transmit coil and clamps the hundreds-of-volts flyback at turn-off. |
| 2 | Receive Front-End 3 parts | 1× | Low-noise amplifier and gated sampler that digitizes the eddy-current decay curve microseconds after each pulse. |
| 3 | DSP Board 4 parts | 1× | Processor that fits decay curves, subtracts the soil response, and maps target strength to audio pitch and volume. |
| 4 | Control Panel 3 parts | 1× | Sealed membrane keypad and indicators for power, sensitivity, and ground-compensation balancing. |
| 5 | Electronics Enclosure | 1× | IP67 polymer case clamped to the shaft, shock-mounted to survive parachute drops and -30 to +55 °C. |
| 6 | Connector | 3× | Mating plug-and-socket pair that joins two lengths of wiring or a cable to a board so a circuit can be assembled, serviced, and separated without soldering. |
