Build your own lab
By: Karim El-Rayes
Build your own lab Do you want to build some electronic projects
at home ???
Do you want to have a small homemade lab for your academic experiments ???
What do you will need to start building your own circuit ???
Tools and equipments you will need
Small digital Multimeter
DMM.
Bread board
Bread board to build your prototype circuits and test them.
AC/DC 12v adaptor
This adaptor convert 220v AC to 12v DC to be your power supply
for your circuit.
Resistors
You will need some
resistors with different
values, these values are
commonly used in
beginners circuits.
Values
330 Ω
1 KΩ
4.7 KΩ
10 KΩ
22 KΩ
47 KΩ
100 KΩ
1 MΩ
100 KΩ variable
Capacitors
You will need some
capacitors with different
values, these values are
commonly used in
beginners circuits.
Values
0.01 µF
0.1 µF
1 µF
4.7 µF
10 µF
47 µF
100 µF
220 µF
40 nF variable
Inductors You will need some
inductors with different
values, these values are
commonly used in
beginners circuits.
However the values
available in the market are
dependable on the market
demand, so no values will
be mentioned.
Diodes
You will need some diodes and full wave rectifiers to use in your circuits.You can use these types of diodes in your circuit: 1N4001 and 1N4004.
Full wave rectifiersThey are the four rectifying diode bridge circuit in one package.Inputs are the ~ terminals and the outputs are the + & - terminals.Bridge part number W005 will be suitable but there is variety in this part so choose what you like to use. Get datasheets for other bridge parts from:www.datasheetcatalog.com
Zener diodes
You may need
zener diodes in
your circuit, use
zener 5v and
zener 12v diodes.
LEDSure you will need some LED’s as indicators in your circuit, but take care to connect a 330Ω or 1KΩ resistor in series with the LED to protect it from over current and voltage.LED has no part number.
Transistors
You will need some
transistors to work on them.
I recommend two types to
work on them.Get datasheets of these
transistors from:
www.datasheetcatalog.com
TIP41 power NPN BJT transistor
2N2222 NPN BJT transistor
Voltage regulatorsVoltage regulators are cheap IC’s used to regulate input voltage by lowering it from higher voltage to a lower constant voltage level, used for protecting electronic circuits.They look like power transistors.Terminals connection:1: input voltage.2:ground.3: regulated output voltage 5v or 12v.Get there datasheets from:www.datasheetcatalog.com
IC#: 7805 5v regulator and781212v regulator
741 Operational amplifier Operational amplifier or shortly called Op-Amp is the basic building block for analog electronic systems, op-amp can perform many functions like amplifier, voltage summer, integrator, buffer and many other applications.use Op-amp IC# : 741, get its data sheet from:www.datasheetcatalog.com
555 timer/oscillator 555 is one of the famous IC in the electronics field, sure will use it in you circuits. It can function many tasks but the most famous function is square wave oscillator.Get 555 datasheet from:www.datasheetcatalog.com
Logic gates If you are interested in digital
electronics you ’d like to use
logic gates.

Wires and connections
You will wires to connect your circuit on the breadboard, I recommend to use Ethernet cable cause it little bit soft and be easily bended and reconfigured inside the circuit.
These wires
Tools you will needWire cutter
Soldering iron
Screw drivers
Plier
Soldering wireSoldering flux
Example #1: simple power supply
5v power supply circuit
Example #2: LED flasher using 555
