Paparazzi Bird Feeder
The Paparazzi Bird Feeder detects the presence of a bird, takes its picture and posts the picture to Dropbox, Twitter or Flickr.
The hardware consists of a Raspberry Pi camera module, a 38 kHz demodulating IR sensor (similar to those used in remote-control receivers) and an IR diode. The entire setup can be powered for hours from a power pack, but is designed for tethered operation.
- Don't take pictures after dusk or before dawn (but record events in the log).
