This project focuses on a common area of power usage in the home- the humble PC. Sure, laptops are more efficient- but sometimes only a PC will do. Many of us leave a PC on just in case we need to log onto it remotely. If we’re not using it, it’s just sitting there using electricity- and usually quite a bit of it. The most efficient desktop PCs still use around 35-45 watts when idling. Gaming PCs with big video cards can easily top 200 watts!
The PiSwitch solution lets you hook up a Raspberry Pi to your PC to control your power and reset buttons. The Raspberry Pi only uses about 1 watt of power when on, so it’s more economical to leave it on all the time. In this article, I’ll walk through how to set up the Raspberry Pi from start to finish to do this.
