Batear is a high-performance, community-driven framework designed to detect and track drone activity using affordable, off-the-shelf hardware. By combining FFT-based acoustic signature analysis with LoRa mesh networking, we are building a decentralized "Acoustic Shield" for privacy and security.

Our goal is to bridge the gap between expensive military-grade sensors and accessible maker technology. We focus on high-fidelity edge computing to provide real-time alerts without the need for cloud processing.
- Real-time Analysis: Optimized FFT signal processing running on ESP32-S3.
- Decentralized Mesh: Long-range notifications via LoRa and Home Assistant integration.
- Professional Standards: Transitioning from prototypes to industrial-grade All-in-One (AIO) PCB designs.

We are currently moving beyond development boards. Our HCB-supported roadmap includes:
- Acoustic Precision: Integrated MEMS microphones (MSM261D35) for superior SNR in field conditions.
- RF Engineering: Validating internal FPC patch antennas for 2km+ range with 3D-printed enclosures.
- Low Barrier to Entry: Providing a standardized hardware platform for our 300+ active cloners.
Batear is a non-profit open-source project. We are currently applying for HCB (Hack Club Bank) support to accelerate our hardware manufacturing and community outreach.
The name is a fusion of "Bat" (nature's master of acoustic sensing) and "Ear". Much like a bat perceives its environment through sound, Batear listens for the subtle mechanical signatures of drone rotors amidst the digital noise.
