I was fortunate enough to get access to a prototype of Pi-Pan from www.mindsensors.com during their kickstarter.
The kickstarter has finished and they reached their goal. However they will be selling Pi-Pan from www.mindsensors.com at a future date.
Pi-Pan provides Pan and tilt movements for your Raspberry Pi Camera.
Pi-Pan can pan 180 degrees (from left to right) and tilt 110 degrees (top to bottom).
Pi-Pan comes with two servos, a controller board, screws, a mount and instructions. It also comes with some python code that shows how the device can be operated.
(The controller board in the image below is a prototype and the production board will be a lot smaller.)
