<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 />

produces six different patterns: horizontal lines, vertical<br />

lines, horizontal and vertical lines (cross hatch), white<br />

dots in a black raster, grey scale, and black raster. Ideal<br />

for TV service, and adjustments.The patterns are<br />

selected by a six position selector. Power dissipation:<br />

MICROPHONE PREAMPLIFIER<br />

A small and useful circuit that amplifies the microphone<br />

signal to line level. It accepts dynamic and condenser<br />

microphone with internal supply. It also operates the 3<br />

pole-condenser microphones. It has two inputs with<br />

different sensitivity.The circuit is based on the<br />

integrated circuit LM833 that ensures low noise, low<br />

distortion, high sound quality and reliability.The gain<br />

can be adjusted by a trimmer to avoid overloading and<br />

distortion.<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 />

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 />
