Editorial Viewpoint
128 Pages: our largest issue ever!
We have a huge issue this month with 128 pages.
There are a few reasons for this.
The first is to celebrate a successful twelve months
as the new publisher of S
ILICON
C
HIP.
My intention
was for the transition to be seamless, keeping up
the same high quality of content and service to our
readers. From your many comments, I believe we’ve
achieved that.
I haven’t made any major changes to the magazine since Leo retired.
It has been around for over thirty years and so must have been doing
something right. As the old saying goes, “if it ain’t broke, don’t fix it”. We
have made a few minor stylistic tweaks, just to freshen up the look and
improve consistency here and there. But that’s it.
I am happy with the quality and variety of our content (and I believe
our readers are too). The only way that I thought we could improve the
magazine was to run more of the same great content. And that’s what
we’ve been doing.
It is obviously more work to produce these larger issues, and it costs a
bit more too. But I feel the result makes it worthwhile. I hope you have
been enjoying the extra content.
As I wrote in response to a letter in the Mailbag section last month,
despite the extra expense involved, the magazine price has not changed,
and I will keep it the same as long as possible. The intention is to give
you, the reader, the best possible value for your money.
Another main reason for the larger issue this month is that it coincides
with this year’s ElectroneX exhibition in Melbourne and we have plenty
of information on what you can expect to see if you attend.
If you’re a Melbournite, or can spare the time to fly down for a day or
two, it’s well worth attending. You will meet lots of interesting people,
see some great technology and you will probably learn something too. I
wish I could go, but publishing a magazine is time-consuming. We are
represented by Glyn Smith, our Advertising Sales Manager, on stand
D18. Call in and say hello! Next year, ElectroneX will be back in Sydney;
hopefully, I will be there in person.
The popular HRSA Vintage RadioFest is also on this month in Canberra,
and we have an article on an interesting ‘farm radio’ in this issue. We also
have some substantial Vintage Radio features coming up later this year.
The final reason for having so many pages in this issue is the monster
article on building a four degree-of-freedom gamer’s seat by Gianni
Pallotti, starting on page 26. Normally we would run such an enormous
article over two or even more months, but there’s a lot to this impressive
design, and it would be difficult to split up.
You need to be confident in your mechanical construction skills to take
on that project, especially welding. But the result is a very impressive
piece of equipment. Even if you don’t think you have the ability to build
it, it’s still interesting to read about how he designed and made it. So
when I saw what he’d done, I realised that we had to publish it.
Dr David Maddison’s article on Cyber Espionage is quite fascinating, but
I won’t go into any details about it here; you will have to read it and see!
So I hope you enjoy this bumper issue. While we can’t promise to do
this very often, I can promise to make S
