When the Raspberry Pi is connected to a car ignition or the USB port on a TV, you run the risk of data loss with a hard shutdown. The Pi UPS bridges short lapses in the power supply and shuts down your Rasp Pi safely when the power remains off.
The Raspberry Pi GPIO interface offers the perfect starting point from which to control devices, such as turning lights on and off, starting the coffee machine in the morning, or turning on the TV and playing your favorite movies at scheduled times.
Your Raspberry Pi comes with many powerful components, but it doesn't have a built-in clock. If your project needs to keep time, and you don't have a reliable Internet connection for NTP updates, you'll need a real-time clock.
In the not too distant future the Raspberry Pi will take off from its humble beginnings on this planet and make a voyage into space. We review the CubeSat Project and talk to Patrick Stakem, an educator and pioneer of open source in space.
