Ring, ring!
I’ve had a mobile phone for 25 years and the changes over that
period in terms of cost, functionality and convenience have
been phenomenal. My iPhone is always at hand, and when I
carelessly lost it earlier in August I’m embarrassed to say it
was quite a trauma! That said, I still have a landline, partly
because it’s part of the package that Virgin Media supply, partly
because I get a better ‘signal’ and don’t drop calls, and partly…
well, simple nostalgia. I’m old enough to remember when a
corded rotary dial phone was all there was, and I like having a
phone on my desk. True, no Bakelite is involved in my current
device – it’s a nice Panasonic DECT cordless model – but it
still feels like a landline… sort of. Anyway, the reason for this
ramble is that for those of you who have an unused old phone
lurking under your desk or in your workshop then we have the
perfect project for you this month. The Tele-com lets you build
a sophisticated intercom with ‘proper’ phones that ring the oldfashioned way. Good fun and well worth a read.
SMD tweezers
The other project I particularly enjoyed in the current issue
shows you how to build a pair of clever, useful and inexpensive
SMD Test Tweezers – simple but elegant DIY instrumentation for
all you SMD fans.
Please!
Most of the communication we receive from readers is via email
– pe<at>electronpublishing.com – and this is undoubtedly the best
way to contact us. However, from time to time we also receive
traditional paper letters, and these are of course welcome too.
But, for those of you who prefer to use ‘snail mail’ I have one
simple request. If you are making an order or expect a reply
then please, please include at the very least your phone number
and better still your or a friend’s email address. All too often
we find that hand-written orders can be hard to decipher or you
forget an important item (eg, your postal address!) and we can’t
proceed with an order or even let you know that your order is
never going to arrive. Just adding your phone number means we
can easily contact you and sort out any issues. Thank you!
