tweety-pi
A Raspberry Pi Camera project that automagically snaps wildlife photos and tweets the images to your chosen Twitter account.
How it works
The project uses modmypi.com's HC-SR501 PIR Infrared Motion Sensor, the Raspberry Pi Camera board (using Dave Jones' excellent picamera pure Python library) and Tweepy (Twitter for Python!). When the PIR senses motion a picture is taken and posted to Twitter.
Simply set the project up by your bird table, or window box and leave tweety-pi to do all the heavy lifting while you work, rest or eat a Mars Bar. Just make sure you've got plenty of bird seed!
I recommend commenting out the update_twitter() function until you've tweaked the sensitivity of your PIR motion sensor so you don't inadvertently abuse the Twitter API.
