I’ve recently taken a job at Ansible working on the enterprise offering Tower. In case you don’t know, Tower is a front-end for your Ansible playbooks w/ enterprise permission management.

Create your own face tracking, pan and tilt camera on the Raspberry Pi! This tutorial will demonstrate use of the OpenCV (computer vision) library to identify and track faces on the raspberry pi using two servos and a USB webcam.
