David Pride wondered one day whether or not he could show that pigeons are intelligent animals. To do this, he created the SmartFrank 3000 (TM) which uses a Raspberry Pi 3B, a motor controller board from PiBorg and a stepper motor to control the release of bird food in response to a button press. The button part has been built to have a very “light touch” so it should react to a pigeon (or other bird) stepping on it.

You can read about the project, and follow along with the results, by keeping an eye on David’s blog.
