WELCOME
to issue 75
T hank you so much for helping us get all the way to issue 75.
We often say it, but The MagPi is a community magazine.
Many articles are written by the Raspberry Pi community;
all our amazing projects are built by the community,
and every penny we make is ploughed back into ensuring
The Raspberry Pi Foundation can train the next generation of
Raspberry Pi makers.
We truly couldn’t make this magazine without the Raspberry
Pi community. You are stars, each and every one of you.
In honour of this massive milestone, we have been working
with the community to choose the 75 Greatest Raspberry Pi
projects (page 14).
It’s an absolute honour to edit The MagPi, but we really
couldn’t do it without our readers. So let’s all raise a glass to
issue 75, and look forward to many more issues to come.

THE WORLD OF PI
Coolest
Projects 2019
Projects 2019
dates announced
A showcase for young innovators,
Coolest Projects is simply inspirational.
Rosie Hattersley reports
B ack in 2012, when Raspberry Pi was merely
a great new idea garnering lots of positive
praise, another excellent innovation
aimed at inspiring young creators was also in
its infancy.
Coolest Projects (coolestprojects.org) began
in Ireland as a science fair and forum for like-
minded inventors to meet and show off their
ideas. Founded by CoderDojo volunteers Noel
King and Ben Chapman, the event has gone from
strength to strength, with thousands of young
scientists and technologists attending Dublin’s
annual Coolest Projects showcase each year.
The event is not just about
the creativity, innovation,
and sheer effort that
everyone puts in, but the
sense of community
This year, Coolest Projects came under the
wing of The Raspberry Pi Foundation, with
events in Ireland, the UK, and North America.
These locations will be hosting Coolest
Projects fairs again in 2019, according to The
Raspberry Pi Foundation CEO Philip Colligan.

Coolest Projects North America will be held
at The Discovery Cube, Orange County on
Saturday 23 March, while RDS in Dublin takes a
turn to host on Saturday 5 May. Ahead of both
these showcases will be the UK event, now in
Manchester at The Sharp Project on 2 March.
Philip says, “Coolest Projects is where
thousands of young people showcase amazing
projects that they’ve built using digital
technologies. If you want to meet the innovators
of the future, this is the place to be.”
For him, the event is not just about the
creativity, innovation, and sheer effort that
everyone puts in, but the sense of community.
If that doesn’t sound like the sort of event a
Raspberry Pi fan might be involved with, we’re
not sure what does.
Registration for all three events opens in
January. Milan, Belgium, and Bulgaria will also be
holding community events that will run roughly
concurrently with the Coolest Projects science
fairs next spring.

PROJECT SHOWCASE
4D Arcade Machine:
Can’t Drive This
A Raspberry Pi-powered arcade display with hidden
interactive controls won over the crowds at Gamescom.
Rosie Hattersley and Rob Zwetsloot got the inside scoop
Machine creator Pixel
Maniacs usually makes
PC and console games
I f you’re going to add a little something extra to
wow the crowd at the Gamescom video games
trade fair, a Raspberry Pi is a surefire way of
getting you noticed. And that’s the way Pixel Maniacs
went about it.
The uremberg-based games developer retrofitted
an arcade machine with a Raspberry Pi to showcase its
intentionally silly Can’t Drive This precarious driving
game (magpi.cc/TphZao) at Gamescom.
Complete with wrecking balls, explosions, an
inconvenient number of walls, and the jeopardy
of having to construct your road as you negotiate
your way, at speed, across an ocean to the relative
safety of the next lump of land, Can’t Drive This
is a fast-paced racing game.
