uilding a Raspberry Pi project sounds so simple.
Take your
favourite single-board computer, add a few parts, sprinkle some
code, and share your creation with the world.
With a few components, you can turn a Pi into a weather station,
EDITOR
or a camera, or a wheeled robot. Building projects is what
The MagPi
magazine is about; it’s what the Raspberry Pi community is about. It’s
what brings us together.
The challenges in project building are as much psychological as
physical. Where do you get good ideas from? How do you get started?
What makes for a good project look? And how can you make sure it
solves a problem (and does so well)?
This month, we look at the nuts and bolts of project planning,
building, and execution (page 26). We’ve asked some of the
community’s greatest makers to share tips and tricks. What makes a
really great project; what kit should you have; how to plan and execute
a project for maximum effect.
The result is a classic tutorial that gets right to the heart of what
it means to be a maker in the
modern world. We’re delighted
with this month’s feature and
found it remarkably helpful. We
hope you do too.
