EDITORIAL
Editor
Welcome to
HackSpace magazine
If you’re reading the paper version of this magazine, you
might notice that it feels a bit lighter in your hand. There
are two reasons for this. The first is that we’re using slightly
lighter paper than in previous issues, and the second is that
we’re now 116 pages per month, rather than 132.
It’s no secret that the print media business is tough and has
been getting tougher for over a decade, but I don’t think even
the most pessimistic forecasters predicted the challenges of
the last few months. At 116 pages, we can ensure that we’re
building a sustainable future for our magazine, so you’ll
continue to get the best makes, hacks, tutorials, and features
every month.
This month, we’re focusing our attention on smart
homes, which is one area makers can have a real impact
on the quality of their personal environment. Whether it’s
monitoring the temperature, controlling the lighting, or
ensuring you’ve got a perfectly brewed cup of coffee ready for
when you wake up, a smart home can make your life better.
Turn to page 36 to find out how.
