After putting up a bird feeder outside our kitchen window we wanted to know if any birds were actually visiting.
The "tweeatery" is project to monitor the bird feeder. A cheap wifi enabled camera board - ESP32 CAM - is used to run a program that checks if the current time is between sunrise and sunset, if it is the board stays awake and photographs the feeder at predefined intervals. The photos are later loaded into a custom program which detects the presence of birds, only keeping images in which a bird is present.
