This month, we have a range of interesting projects for readers to build
but two are especially noteworthy. The first is the "Woofer Stopper" which
may have a whimsical name but it is intended to help solve the very
common problem of barking dogs. It is a great pity that so many people are
bothered by barking dogs, particularly as the dog owners either are oblivious to the problem or deny that their little darlings ever bark.
As presented, the "Woofer Stopper" can be very effective against dogs
that are close to your home, say within 20 or 30 metres. In that situation, it
can work like a charm and without the offending dog owner even knowing
that you have taken action. On the other hand, the "Woofer Stopper" is a
partial solution to what is really a sociological problem. In the long term, I
hope that people and municipal councils will come to recognise that unless
dogs are properly disciplined and are not left alone for long periods every
day, they do become a nuisance.

Our second project which is worthy of note is the "Remote Volume
Control" which is based on a 68HC 705C8P microprocessor. At first sight,
this may seem like a complicated alternative to the remote controlled
motor-driven volume controls now seen in many domestic hifi systems.
However, it solves the problems of having to obtain special volume and
balance pots and is a superior solution as far as performance is concerned.
It also represents a step forward for us in that we can now present dedicated
microprocessor projects and we will be supplying the programmed microprocessors to kit sellers and individual readers.

And finally, we have some news of an even bigger step forward . In the
near future, SILICON CHIP will be published in the United States and
Canada. Gernsback Publications, Inc of New York, who presently publish
Popular Electronics and Electronics Now (formerly Radio Electronics), will
initially be publishing four issues a year of SILICON CHIP and most of the
editorial will be reprodllced from Australian issues.

will give us a boost both locally and overseas. To our knowledge, it is the
