Keep calm and solder on!
These are strange and unnerving times, but we have to make the
best of it. Doubtless, each of you has your own coping mechanisms
for staying sane, and I hope PE is playing a small part in helping
you pass the time productively. Electronics is a great way to engage
the brain and keep occupied.

With that in mind, I’m grateful to reader Alan Macdonald for
pointing out that last year we carried the perfect project for the
current situation – I mean of course Jake Rothman’s Theremin.
As Alan quipped in an email exchange with me when discussing
the project – ‘it seems like a good way of spending time during
lockdown, with the added bonus that since you don’t touch it, you
don’t have to clean it!’

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 maga ine. 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.
Transmitters/bugs/telephone equipment
We advise readers that certain items of radio transmitting and
telephone equipment which may be advertised in our pages
cannot be legally used in the UK. Readers should check the law
before buying any transmitting or telephone equipment, as a fine,
confiscation of equipment and or imprisonment can result from
illegal use or ownership. The laws vary from country to country;
readers should check local laws.

This issue
As always, we have something for everyone in this month’s
magazine. From an RF Signal Generator for radio enthusiasts to a
Mini-organ for the musically inclined, I’m sure you’ll find material
that will keep you inspired and entertained. I particularly enjoyed
Ian Bell’s explanation of class-D, G and H amplifiers, and Phil
Boyce’s Micromite Robot Buggy is just the kind of original project
that makes PE special. Read on and enjoy!
The PE PCB & PIC Service
I was hoping for a loud fanfare of trumpets for our new PIC service
– but so far it is quite a modest affair, so I’ll settle for a quieter
announcement. The good news is that it is up and running, and
if you want a programmed PIC for a project that has appeared in
PE then look for it in our online shop in the PCB section – soon
to be renamed the PE PCB & PIC Service. Not all possible PICs are
available yet. Those that are, sit alongside the relevant PCB for a
particular project, arranged by issue month and year. At first, we
will stick to the most common PICs – all DIP packages – and then
slowly expand to cover other devices and package types.
Thank you!
Last, I would like to thank the many businesses that are working
hard with us in very difficult circumstances. Quite simply,
without them you would not be able to read these words. PE
is very fortunate to have great support from our printer (Acorn
Web), distributor (Select Publishing Services), partner magazine
in Australia (Silicon Chip) and the numerous postal services in
the UK and around the world that have helped keep our magazine
going – thank you one and all.
Keep well everyone
