Editorial
Something for everyone
There’s a pleasing variety of material in this month’s issue
of Practical Electronics. From fixing ancient amplifiers and a
fascinating visual trip down Memory Lane to building and using
the latest microcontroller technology. So let’s dive into a more
detailed look at this month’s magazine.
tekkiepix.com
It’s always a pleasure to read Barry Fox’s eponymous column,
and this month I asked him to write a little more about his new
website devoted to saving and archiving important images related
to the history of electronics, especially consumer products. For
those of you unfamiliar with his work, Barry has been a leading
UK electronics, IT and technology journalist for decades. Through
his work he’s created an important archive of images that need
preserving and has launched a website to do just that. Please do
pay a visit to tekkiepix.com, click on the Stories link and enjoy
the material. If you are able to support his work and make a
contribution, however small, then all the better.
Projects
Some audiophiles look down on graphic equalisers as an
unnecessary, signal-damaging link in the Hi-Fi chain. I’ve always
thought that was rather unfair; they do have their place and can be
very useful in challenging acoustic environments. So, if you’re in
the market for a high-quality, low-cost design then this month we
have just what you need. Even better, it comes in mono and stereo
flavours, so why not give it a try?
Plus, we have the second and final part of our DIY Reflow Oven
for those of you who make your own SMD PCBs and a fun Digital
Altimeter especially suited to use in cars.
Digital fun
Where to start? Our authors really are excelling themselves this
month. We have Max’s wonderful ping-pong ball array playing
Conway’s Game of Life, Phil Boyce’s must-read column on using
the Micromite with the Internet and the latest from Mike Hibbett’s
exciting PIC18F Development Board. Truly, a feast for all fans of
digital electronics and microcontrollers.
You want more? Well, naturally we have in-depth analysis from
the word of electronics courtesy of Ian Bell’s Circuit Surgery, and
the start of a super high-quality Microphone Preamplifier from Jake
Rothman in Audio Out.
Truly, something for all tastes!
Keep well everyone
