Technical enquiries
We regret technical enquiries cannot be answered over the
telephone. We are unable to offer any advice on the use, purchase,
repair or modification of commercial equipment or the incorporation
or modification of designs published in the magazine. We cannot
provide data or answer queries on articles or projects that are
more than five years old.
Questions about articles or projects should be sent to the editor
by email: pe<at>electronpublishing.com
Projects and circuits
All reasonable precautions are taken to ensure that the advice and
data given to readers is reliable. We cannot, however, guarantee
it and we cannot accept legal responsibility for it.
A number of projects and circuits published in Practical Electronics
employ voltages that can be lethal. You should not build, test,
modify or renovate any item of mains-powered equipment unless
you fully understand the safety aspects involved and you use an
RCD (GFCI) adaptor.
Component supplies
We do not supply electronic components or kits for building the
projects featured, these can be supplied by advertisers. We
advise readers to check that all parts are still available before
commencing any project in a back-dated issue.
Advertisements
Although the proprietors and staff of Practical Electronics take
reasonable precautions to protect the interests of readers by
ensuring as far as practicable that advertisements are bona fide,
the magazine and its publishers cannot give any undertakings
in respect of statements or claims made by advertisers, whether
these advertisements are printed as part of the magazine, or in
inserts. The Publishers regret that under no circumstances will
the magazine accept liability for non-receipt of goods ordered, or
for late delivery, or for faults in manufacture.

Editorial
Getting the balance right
‘Time flies’ – I know, this is not news, but still, I find it hard to
believe that this issue is my 24th as publisher. The last two years
really do seem to have just flown by. Although anniversaries are
largely arbitrary, this does seem like a good opportunity to ask
you for your opinion of what you like (and dislike) in PE; in other
words, what you’d like to see more of, and what you skip over.
Probably the toughest editorial task has been getting the balance
of the magazine right. There are many conflicting demands and
requirements from readers who range from absolute beginners to
seasoned professionals and educators. Some of you are diehard
analogue fans, others enjoy adding a microcontroller to every
circuit imaginable. We have project builders who each month
order an impressive number of PCBs, and there are others who
simply want to read and learn how things work.
Everyone’s background is different, and impressively, we have
many subscribers for whom English is not their first language.
Understanding electronics can be challenging enough without
having to wade through a foreign tongue – so we do appreciate
all the extra effort made made by our many subscribers from the
distant corners of the globe.
Wherever you are, whatever your level of training, education
or interest, we want to hear from you. It is feedback that lets
me and our talented writers get a feel for what you want to read
in Practical Electronics. Do please let us know if you have any
comments or ideas. We can’t accommodate every suggestion, but
when we can, we do – this month’s Circuit Surgery being a nice
example of a reader making a suggestion which became the focus
of a whole article.
Ideas, comments, criticism are always welcome – just send us an
email: pe<at>electronpublishing.com
Is it too early to mention Christmas… again?
Well, it’s clear you like LEDs and Christmas trees! We ordered
several hundred little PCBs for last month’s LED Christmas Tree
project, and we sold them all. More are on their way, so if you
fancy something inexpensive, fun, festive and electronic then do
see the special offer on page 33.
Keep well everyone
