Could you build this?
No An acoustic drone detector on a $15 edge device requires physical microphone hardware, embedded digital signal processing, and a custom micro-ML classification model tuned to drone acoustic signatures.
What it would actually take: Built on microcontrollers like the ESP32 or Raspberry Pi Pico with an I2S MEMS microphone array running FreeRTOS. The critical engineering challenges are low-power edge digital signal processing (FFT, Mel-frequency spectrograms), training an audio classification neural network on sparse drone acoustic data, and quantizing it (via TensorFlow Lite for Microcontrollers or Edge Impulse) to fit micro-SRAM limits.

Same idea, different domain
Nobody's really built a hardware & robotics tool for Horizontal yet.
