PUBLISHER'S LETTER
Going for the big clean-out
Are you reluctant to throw out old electronic components? If you are anything like me,
you are. I hate to see electronic equipment or
components being junked. However, while
this may be a good and worthwhile attitude
and may often save you money in the long run,
there is the other side of the coin to consider.
After a while, you get too much junk.
About a year ago I moved house and there
was a lot of stuff that I didn’t have time to
sort out at the time so it all went into boxes
“to be looked at later”. Now I am slowly wading through it. I have to face up
to the fact that I have “electronic stuff” that I haven’t touched for 20 years or
more. Much of it, and I am talking about all sorts of small components here,
is probably still as good as the day it was made. But I’ll never use it; not ever.
I’ve had to bite the bullet. Some stuff I’m saving and some I’m giving away
but a good deal of it has to go in the bin – there’s just no way that anybody
would use it. Some of the components I’ve had so long that the leads have
corroded; that’s a hazard of where I live, close to the sea. Inevitably too, there
is stuff that I didn’t know I had and some that I thought I’d lost or given away
years ago.
I am sure that there are many readers who are in a far worse situation. Instead of half a dozen boxes of junk, they have a shed, a garage or even rooms
full of it. Like me, they will probably never use it. And sooner or later they
will have to face up to doing something about it, especially if they ever have
to move to a smaller house. If you are one of these people, why not attack the
problem this evening? You will feel a lot happier when it is sorted out. You
will probably find that you have so much more room to move as well and
you will be able to accommodate all that new stuff you want.
You have to be ruthless about it. If you find something that you have had no
use for in the last five years, it probably should be given away or pitched out.
Any components which look corroded or discoloured in any way should be
tossed as well. If you can find an electronics club that wants your electronic
bits, so much the better. In fact, if electronics clubs thought about taking
small classified ads they would probably end up with a lot of good material.
While you’re in clean-up mood, why not sort out all those floppy discs
around your place? Reformat them and put them back into general use. You
can do the same with all your VCR tapes. You’ll probably be amazed at how
many you have lying around.
So have a look around you and see if you’ve been hit by the “hoarding
virus”. It is curable and most people live happily thereafter.
