screens, and never think to ask what’s going
on behind the glass. We want computers we
can hack, make, and break (and for it not to matter),
and that’s exactly why we love the Raspberry Pi.
The Raspberry Pi is about GPIO pins and wires, and
the Linux OS. It’s about making something, and
messing up everything, and it not mattering because
there’s always another chance.
We love it.
But what would it be like to use all the time?
Would using a Raspberry Pi every day of the week be
digital heaven, or computing hell? That’s the task
we set our intrepid Features Editor Rob Zwetsloot.
Spend a week working with a Raspberry Pi – nothing
else allowed. And let us know what it’s like: warts
and all. You can read all about it on page 16.
The Raspberry Pi is a glorious piece of kit, and
it’s a shame to keep it in the shade. It is perfectly
portable and ideal for aerial balloons, outdoor
cameras, weather stations, and all manner of
fresh‑air projects. We have twelve amazing summer
projects for you, starting on page 68.
So whether you’re installing a Raspberry Pi
permanently in your home, or taking it outside
to play, what’s important is that you’re using the
world’s most interesting computer. And let us know
how you get on.
