Smart Electronics is synonymous to High Quality electronics since
1980.The company is well known to generations of professional,
educational, and hobby enthusiasts all around the world.
There are thousands of people who learned electronics using our kits
and today are electronic engineers and well known professionals.
From Island to S.Africa and from USA to Hong Kong , Smart Kits are
exported in many countries and they are famous for their quality and
well known as best value for money products.
During last year we worked very hard to improve our range.We
created new kits -some of them using of microcontrollers- and we
redesigned some others.The majority of the kits now have the CE
approval and its a matter of time to get the approval for all the rest.
We also paid the proper attention to offer you the right information. In our site at Internet
www.smartkit.gr you will find all the info about Smart Kits in English, German, Dutch, Danish,
Swedish, Italian, Spanish, Portuguese, French, Hungarian and Greek.The most of the kits have
already multilingual instructions in 8 languages.This catalogue is also among our efforts to provide
you the info that you require to make the right selection.Try a Smart Kit!
WHAT IS A SMART KIT?
It is an easy way to build an electronic device such as:A.F. amplifiers, F.M. transmitters, alarms,
power supplies, instruments, light modulators bugging devices etc.Apart from that, there is a great
fun in building electronic circuits, you can also feel very proud for your creativity and of course
you have a chance to learn a lot!
Furthermore you can save a lot of money because kits cost less than assembled devices.
A Smart Kit pack contains everything that you need to build the circuit.All the components,
printed circuit boards and instructions -usually in your language- are included in the package.All
you need is, just a soldering iron!

components of the kit, even the solder, are included in the pack.A
careful reading of the instructions and a soldering iron are all you
need, and you your kit will be ready use.
ñ If you wish your kit to look professional, the only thing you need is
using a smart box.All the boxes are silk printed, drilled and are the
ideal housing for smart kits. In order to choose the right box, you just
have to remember that they have the same code number as the
corresponding kit.The only difference is that the first digit from the
P/N of the kit «1» is replaced by the number «2». (e.g. smart box 2014
for the kit 1014).
ñ Do you wish to buy a popular kit as a ready made electronic
apparatus? You can select any one from our 5000 line.All the units are
professionally assembled and cased in a smart box, fully tested,

MOTORBIKE ALARM
A project that protects your beloved motorbike. It uses
a simple vibration sensitive contact that detects the
slightest movement of the motorbike (the sensitivity is
adjustable) and triggers the alarm.When the alarm is
triggered the output relay closes and its up to you to
connect across it a siren, (e.g. 1003) the motorbike’s
horn or any other warning device.The circuit has a preset
alarm time.When that elapses it resets automatically.
