OATLEY ELECTRONICS - take note of
our low prices and some May 1988
specials on kits and ready made items.
FM Stereo Transmitter: yes, this unit
transmits the complex FM multiplexed
stereo signal to any conventional FM
stereo receiver! And it's not a kit - it's
ready made, housed in a small enclosure
(72 x 38 x 21 mm) and powered by just
one 1.5V AAA battery with a life of 100
hours. Unit transmits on 90 .35MHz and
is tunable from 89 -91 MHz; automatically
switches on when an audio signal is applied to its input and automatically switches off about two minutes after the input
signal ceases . Input impedance is 32
ohms, range is about 15 metres (less
than 15mV/metre at 100 metres), and
the unit has a mono-stereo switch. Input
signal is obtained via a standard 3 .5mm
stereo plug which can plug directly into
the headphone outputs of your hifi
equipment, stereo TV, " Walkman"
cassette player, compact disc player etc.
For example , you could use it to transmit
a stereo signal from your house hifi or TV
to your Walkman or car stereo. Great for
people with hearing problems and people
who like loud music without disturbing
their neighbours. During May, we will supply the Stereo FM Transmitter for an
unbeatable price of only $59.95 plus $2
p&p - and we'll include two 1.5V AAA
alkaline batteries in the price.
Remote Controlled Ultrasonic Car
Burglar Alarm: this is not a kit - it's a
complete commercial alarm. Unit is
remote controlled by a small keychain
transmitter, has a self-contained untrasonic movement detector which
mounts on your dashboard, and a
siren/alarm unit which would normally be
mounted in the engine compartment. Installation is made simple by employing a
pre-wired loom which includes connectors! Even the pin switches (eg , for bon-

net/boot protection) and the alarm
stickers are provided . Features include
ultrasonic movement detection , digitally
encoded UHF remote control (8-metres
range) , 60-second exit delay, no entry
delay. Armed with ignition key, auto reset
after a 1-minute alarm, LED status indicator and panic button on ultrasonic
movement detector. Suits 1 2V negativeearth vehicles. Compare this unit with
other commercial alarms and realise that
this unit is a true bargain at only $129.95
plus $5 p&p.
Car Battery Isolator: you can easily add
back-up battery operation to the above
alarm or to any other alarm with our car
battery isolator. Isolates the car's battery
and charges the back-up battery. All you
need to add is a 1 2V rechargable battery
(read on). The back-up battery isolator is
priced at only $5.50 plus $1.00 p&p.
Satellite Siren (Sept.87 EA): perhaps
this unit is better referred to as a Back-Up
Siren. Add the protection of this complete second alarm system into your
existing alarm system. Automatically gain
the benefit of back-up battery operation
and a complete and remotely placed
second alarm system . This unit is simple
to install; it only requires two connections
to your existing alarm system. It comes into action when the main alarm is vandalised, the main alarm power is interrupted or the vehicle battery is
disconnected. For the month of May we
are offering a complete kit for the Satellite
Siren at a very special price. What's in
this kit? - PCB and components, battery holder, barrel key switch (with two
keys), a su itable plastic box, four
rechargable nicad batteries (penlite),
and a 12V mini piezo siren (that's
everything you 'll need). Add up some of
the normal prices for the items listed and
realise that this project is a May bargain at
only $44.95 plus $2.50 p&p.
Ignition Killer: let's the burglar get away
with your car for a few seconds only. The
car then stops and is able to be restarted
after a few seconds , then it stops again
and so on. This kit also includes the
required external hidden switch . The
design is almost identical to the very
popular one published in EA except that it
uses an economy heavy duty relay. The
complete PCB and components kit for
this project is available during the month
of May for a giveaway price of only $9.95
plus $1.50 p&p.
