How do you transmit the audio once captured?

My setup took maybe ~4-8h of initial work. All with the help of Codex: code, configuration, even figuring out which equipment to buy.

I tried that with my Aqara camera. The mic there has no windshield, though; wind noise was terrible. Also I couldn’t get Aqara support to enable higher sampling rates in the firmware than 16kHz; BirdNET expects 48kHz audio samples.

Ended up installing a better microphone attached to a RPi3A+ and using a RaspberyPi 4 which I already owned for hosting BirdNET-Go https://maciejb.me/posts/birdnet-go-setup/

Much better sound quality now!

I had plenty of fun reverse engineering a 433.92 MHz protocol curtain motors at my house use. Once that was done and I taught first my Flipper Zero, then a RPi with a C1101 to actuate the motors, the Flipper is sitting idly in the drawer.

Next time I see a plane coming, I’m going to lie on the floor to see if the whoosh sound does it fact change.

Great story! Thank you for sharing your experiences!

I'm curious how did you find out about the event in the first place?
