Two sets of simple to follow instructions to turn a Raspberry PI into a web server from Instructables and WikiHow. The total power consumption for a Raspberry Pi over the course of a year is roughly £3.50 (400 milliamps per hour), so it’s ecologically friendly too.

Other uses for a Raspberry Pi include:

A Minecraft server.

An OpenVPN (from Remi Bergsma’s blog) or private VPN – perfect to create a secure connection to the internet from a non-secure location (let’s say, Azerbaijan).

A BitTorrent server.

A web cam server.

A personal cloud. And here is an interesting file storage idea.

PingBin has some more outlandish ideas too.

Or, you could even send your Raspberry Pi into space.
