If you have not heard of the Raspberry Pi yet – or just Pi or rPi for short – you really should learn about it. Soon!

Kids learning computers

The Raspberry Pi is a very small computer that was designed to help children learn about computers and how they work. Although it can be used as a platform for kids to learn programming skills, it can also be used to learn about robotics, remote sensing, and almost anything a computer can be used for. Because of its low price and small form factor, the Pi is also extending the ways in which computers are being used.

One of the amazing things about the Pi is its $35US price tag. Of course by the time you add a small case,, keyboard, mouse, and display, the cost is a bit more, but $35 is very low for just the computer itself. This provides access to computers for low-income students and the schools they attend in a way never before possible.

Grown-up uses

But the Raspberry Pi can be used for much more than that. Many of us hackers have found important real-world uses for our Pi computers.

I personally have two Raspberry Pi’s performing firewall duties for my network. These Pi’s replace two much larger and more expensive computers that used to perform the same functions. They do this easily and quietly, running day after day to protect my network. And sometimes I have hundreds of individual attacks on my network in a single day so it is an important function.
