THE
ONLY
PI MAGAZINE WRITTEN BY THE READERS, FOR THE READERS
Welcome
WELCOME TO
THE OFFICIAL
PI MAGAZINE!
L
ife can be hectic, can’t it? At times like this,
it’s the little things that suffer. You forget to
record your favourite TV show, you miss the
weather report, or – worst of all – you end up drinking
cold coffee. As our features editor Rob Zwetsloot
explains at the start of this month’s cover feature,
while technology has advanced to a point that we can
navigate the globe with a tiny monolith stored in our
pockets, there’s still too much to do and too little time
to do it. There’s tons of great technology out there –
all we’ve got to do is find new and interesting ways to
make to work in our favour. The Raspberry Pi is the
perfect example and we’ve put together five projects to
demonstrate how you can use it to power up your life.
You can get started today on page 20 – and, if you’re
inspired by our ideas, do let us know what little life
hacks you have in mind using the Raspberry Pi.
For our other big feature this month, we’ve put
together a top-secret dossier of James Bond-inspired
hacks that Q himself would be proud of. Get started on
page 66 and see what top-secret intel you can gather
with these rather mischievous Raspberry Pi projects.
Enjoy the issue!
