I modified a No-Face model from Printables and scaled it up to max out my EufyMake M5 build volume. I customized the face area to act as a parabolic microphone cone to help direct and amplify bird calls toward the mic. I put some foam in the cone to prevent wind noise and covered the face of the cone with white cloth.
The Pi is running BirdNET-Pi, with both a GPS module and MEMS microphone wired to GPIO of the board for autonomous bird monitoring and geotagging. BirdNET-Pi runs bird detection entirely on the hardware, no internet needed, but it's pushing the limit of the Pi 02W and has reboot problems in extreme heat.
Hardware:
- Raspberry Pi Zero 2 W
- GPS: Doudou GT-U7 GPS Module (NEO-6M compatible)
- Microphone: INMP441 Omnidirectional MEMS I2S Microphone
- PSU: 15W 5V 3A Micro USB Power Supply
