Field notes
The described node combines a Raspberry Pi 5, a four-microphone array, and a Remote ID receiver; the page gives a parts estimate of about $230 before optional field-use equipment. Its detector requires agreement in two of three half-second windows, while audio is described as staying in a one-second buffer rather than being stored. The dashboard description includes node temperature, disk space, uptime, and a 15-second check-in.
