Arduino Power Strip

For those of us that keep servers at home, for whatever reason, the jump between consumer grade and professional grade hardware can be significant. While it has gotten much cheaper in recent years to build a server, things like networking equipment and power management remain fairly expensive. One of the most useful tools in a server admin’s arsenal when trying to remotely manage hardware are power strips that can force a server to power cycle by cutting power to the outlet. It’s not something you do often, but it’s can come in handy. Recently Alberto Panu released the details to a project that takes an Arduino and turns it into a Telnet-capable power strip.

Like any Arduino project that requires playing with electricity, this is not for the casual enthusiast. The project details a DIY method to build a box that allows you to connect up to six items to mainline power and control them by logging in to the microcontroller in the box and issuing commands to either cut power entirely or cut power and then restore ita connected device. This same project could be easily adapted for a much simpler power strip that used residential outlets, but that is very different from what was done here.

Once the box was built, all you would need to do in order to use it would be to log in via Telnet. For example, if you had a terminal client installed on your phone you could login and control the power from anywhere.

While this implementation is certainly a bit more industrial than what an average tinkerer would build in their free time, it is undeniably cool to see Arduino used in such a way.
