Build your home electronics lab: For beginners

• 
  
•  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 equipment you will need  are as follows:
• 1. Small digital Multimeter DMM.
• 2. Bread board Bread board to build your prototype circuits and test them.
• 3. AC/DC 12v adaptor, this adaptor convert 220v AC to 12v DC to be your power supply for your circuit.
• 4. Resistors, you will need some resistors with different values, these values are commonly used in beginners circuits. Values 330 1 K 4.7 K 10 K 22 K 47 K 100 K 1 M 100 K variable
• 5. 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.
• 6. 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.
• 7. Diodes You will need some diodes and full wave rectifiers to use in your power subcircuits. You can use these types of diodes in your circuit: 1N4001 and 1N4004.
• 8. Full wave rectifiers They 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
• 9.. Zener diodes You may need zener diodes in your circuit, use zener 5v and zener 12v diodes.
• 10. LED Sure you will need some LED’s as indicators in your circuit, but take care to connect a 330 or 1K resistor in series with the LED to protect it from over current and voltage. LED has no part number.
• 11. 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
• 12. Voltage regulators. Voltage 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 and 7812 12v regulator
• 13. 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
• 14. 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
• 15. Logic gates If you are interested in digital electronics you ’d like to use logic gates. Mentioned in this table 74xx TTL logic family part numbers. Part number Description 7400 NAND 7402 NOR 7404 NOT 7408 AND 7432 OR 7486 XOR 7474 D-flip flop 7476 J-K flip flop 7448,7447 7 segment driver 7407 Open collector buffer
• 16. Some other digital modules Mentioned in the table some other digital modules you would like to use. For more information get there datasheets from: www.datasheetcatalog.com Part number Description 74154 4x16 decoder 74151 8x1 Mux 7490 BCD counter 74393 Binary counter 74373 Tri-state latches 74245 Octal buffers
• 19. 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
• 20. Tools you will need Wire cutter, Soldering iron, Screw drivers, Plier Soldering lead.
