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

through a telephone pick-up coil (included in the kit)<br />
and will let you follow a telephone conversation<br />
without having to hold the telephone receiver in your<br />
ear. It is also very useful when more than one person<br />

PROTECTION FROM MALICIOUS CALLS<br />
A simple and useful circuit that will ensure your<br />
protection from malicious calls, with an easy and<br />
certain way that you are able to change at any<br />
moment.The heart of the circuit is the PIC<br />
microproccessor 16C56, that cuts off the first rings<br />
(adjustable from 3 to 12), thereby the caller will hang<br />
up thinking that you’re absent.You are going to hear<br />
the call after the rings that you chose to cut off.<br />
TELEPHONE LINE RECORDING<br />
A very clever device that will activate a cassette<br />
recorder when the telephone receiver is lifted. It is<br />
very useful for the recording of commercial orders<br />
over the telephone, conversations, security etc. It<br />
draws its power from the remote control line of the<br />

TOUCH DIMMER<br />
This is a very modern dimmer that only needs a light<br />
touch to operate.A light tap on its sensor will turn the<br />
light ON or OFF.A longer touch will either increase or<br />
decrease the light level.The circuit incorporates a<br />
memory and switches the light on at exactly the same<br />
level it was before switching it off.Very safe and stable<br />
operation. Max. current: 3.5 A.<br />

AUTOMATIC DIMMER<br />
It is a circuit that adjusts the lighting of a room<br />
according to the environment lighting.The more the<br />
outside lighting lows down the more the room lighting<br />
raises and vice versa, thanks to a sensitive<br />
photoresistor.The circuit is used to poultry-farming,<br />
design studios as well as child room.<br />

MINI DRILL SPEED CONTROLLER<br />
An easy to build stabilised special power supply for all<br />
the hand mini drills.A useful project that lets you<br />
adjust the speed of your mini drill according to the job<br />
at hand.The speed is not affected by the hardness of<br />
the material you drill.The output voltage and sensitivity<br />
can be adjusted by two potentiometers.The circuit is<br />
built around the well known regulator IC L200. Output<br />
voltage: 4-26VDC. Output current: 3-5A.<br />

8CH TIMER CONTROLLED BY P.C.<br />
Using this <strong>Kit</strong> you can control 8 devices.The kit is<br />
connected to the serial port of your computer and<br />
defines when will turn on or off each one of the 8<br />
devices. For example you can turn on/off the lights, the<br />
air conditioning or the alarm at the desired time.There<br />
are 3 options - manual, periodic, automatic - for the<br />
handling of the <strong>Kit</strong>. Power handling up to 500 Watt<br />
/channel.The software is also included in the same<br />
package.<br />
ADC COMPUTER INTERFACE<br />
A circuit that will expand your horizons for more<br />
efficiency in your PC. It is about an A/D converter<br />
build around the ADC0804.The circuit is provided with<br />
the software for best processing from the PC and is<br />
connected to the parallel port giving you by this<br />
connection three digital outputs. It can also coopertate<br />
with microcontrollers. Power supply 5 VDC.<br />

Looking at the <strong>catalogue</strong> you will notice the existence of<br />
the following signs:<br />
The meaning of each of the signs is explained in the<br />
following lines:<br />
The kit has the CE approval accdording to the<br />
EC regulations (European Directive 89/336/EEC).<br />
The kit operates/produce 220V or a High<br />
Voltage.Therefore must be constructed by skilled<br />
technicians following safety standard as described by<br />
international specs and regulations.<br />
The kit transmits radio frequencies.The operation<br />
and use of such devices may be controlled by regulations<br />
that differ from country to country.The compliance with<br />
the corresponding legislation of each country is obvious,<br />
The kit must be connected to the network of<br />
PTT.The operation and the use of such<br />
devices may differ from country to country.The<br />
compliance to the correspponding legislation of each<br />
country is obvious.<br />
Beside each kit you will find useful information<br />
quick form.There you can see at a glance the<br />
required voltage (V), the suitable kit to use as a<br />
power supply (P.S.), the required transformer (T)<br />
and the PCB dimensions (PCB).<br />
