The Raspberry Pi is a credit card size low powered compute board with Ethernet connection, HDMI video output, audio, full Linux operating system run from an SD card, and more, all for $45. With cables, SD card, etc., the cost is about $70. Originally designed to help teach computer science principles to low income children and students, the Pi has taken on a life of its own, with many online resources and projects that cover most everything one would want to do with a small low monetary cost and low battery power computer. This paper/session will present the Raspberry Pi and provide ideas of what it can do and how one can get started using it. The author has used Pi's for Internet data acquisition/monitoring, cluster processing using more than one Pi, email notifications, and power monitoring. The particular focus example will be on UPS power monitoring and status using off the shelf Open Source software. The main software for the purpose of power monitoring is NUT, Network UPS Tools, whose goal is "to provide support for Power Devices, such as Uninterruptible Power Supplies, Power Distribution Units and Solar Controllers." Some background in the theory and practice of electrical power, surge protection, uninterruptible powers supplies, etc., will be provided. [For full proceedings, see ED571297.
