Not the most conventional application for self-hosting, but thought it might make for a fun weekend project for someone.
BirdNET-Pi is built off the back of Cornell University’s BirdNET Sound ID neural network model (https://birdnet.cornell.edu/). It can be used to classify what birds are in your vicinity by listening to their calls.
BirdNet-Pi is awesome. Highly recommended for anyone who likes birds. The BirdNet app for phones is also nice.
Btw, BirdNet-Pi also works fine on the non-plus Raspberry Pi 3.The default install instructions explicitly prevent installation on a Pi3 or Pi3+. If you have armv7l cpu architecture, the script just exits. I banged at it for a bit, but the tensorflow lite runtime install tripped me up. Going to look into the docker project mentioned elsewhere in this thread instead.
