We regret technical enquiries cannot be answered over the

All reasonable precautions are taken to ensure that the advice and

it and we cannot accept legal responsibility for it.
A number of projects and circuits published in Practical Electronics

modify or renovate any item of mains-powered equipment unless
you fully understand the safety aspects involved and you use an
RCD (GFCI) adaptor.

projects featured, these can be supplied by advertisers. We
advise readers to check that all parts are still available before

Editorial
The PIC series we’ve all been waiting for
Probably the question I am most-often asked by readers is, ‘how
can I learn to use PICs?’. It’s not an easy question to answer
because PICs cover a huge range of devices. Nevertheless, I have
always wanted to provide an easy-to-understand, comprehensive
guide to using these vital devices.
Well, the big news in this issue is the start of a brand new
series in PIC n’ Mix devoted to mastering the PIC18 family of
microcontrollers. You can read all about Mike Hibbett’s plans for
this hands-on educational project in this month’s column.
The PIC18 family is made up of sophisticated 8-bit devices that
offer flexibility, power and enormous interfacing opportunities.
The series will teach you how to add Wi-Fi, USB and much more
to PIC-based projects. I’m really looking forward to reading it,
and I’m sure you will enjoy finding inspiration to build your own
PIC18-based projects.
Calling PE Gemini builders
We recently received an email from reader Steve Moreham:
‘Back in December 1970 I started building the PE Gemini, which
I still have and want to get going again. Do you have the back
issues? I do have some very tatty and faded photocopy pages (but
incomplete). I built this amp as the issues came out when I had
just started an electronics degree at Newcastle Poly.’
As always, Alan Winstanley, our Net Work guru / online editor /
senior PE archivist came to the rescue, and we were able to send
Steve a complete set of the five articles in PDF format. Are there
any other Gemini builders out there who can offer some advice
on building/running/tweaking this Hi-Fi pre-/power amp from 50
years ago? Just send me an email and I will be sure to pass on any
assistance to Steve.
Keep well everyone
