SCANNER-v0.1 · named unit

Stachelschwein DDS Scanner v0.1

A Raspberry Pi 5 on a roof, two ears, a cable into the house, detections to the Wunderglobe monitor.

01 · Not four cameras

Two ears in v0.1. Four capsules on one of them.

Ear 1 is Remote ID, one radio. Ear 2 is sound, four microphones as one array. Broadband RF and the camera wait for v0.2.

The four mics are not four data streams. They are four capsules that add up to one acoustic picture: louder signal, a rough direction. Fibre-optic FPV has no radio. That is why the array exists. Remote ID is a different ear. It hears the legal plate the EU made drones shout since 1 January 2024.

Ohr 1 · RID
ESP32-S3 with an antenna outside the box. Hypothesis 400 to 1500 m in open field.
Ohr 2 · Sound
ReSpeaker 4-mic. Vendor speech range 5 m. Rotor hypothesis 80 to 250 m on a quiet roof.
Brain
Raspberry Pi 5, 4 GB, 5 V / 5 A. Packs DETECTION and POSTs it to the central.
Central
Wunderglobe, for now. A Germany map, blinking nodes, later verification. Anyone with a unit can plug in.

The range lever is the antenna outside the shell, and the roof height. Putting the ESP32 inside a metal box with its PCB antenna is how you buy 12 euros of silence.
