WEEK 4

TITLE OF ACTIVITY : Search and buy the component.

OBJECTIVES : 
-Finding paths shop that provides the necessary components.
-Meets the necessary components.

METHODS :
-After identifying the components needed, we moved to Jalan Pudu market because there are readily available electronic components.


RESULT :
-We managed to get the required components.

COMPONENTS LIST
Resistors:
R1 = 15kΩ
R2 = 22kΩ

(Wima)
Semiconductors:
D1 = LED, red, low current
D2 = 1N4148
D3 = 1N4002
D4 = 18V 1.3W zener diode
D5,D6 = BYV27-200
IC1 = LM393N
IC2 = SG3526N
T1,T2 = IRFP054N (IRF)
Miscellaneous:
X1-X6 = AMP spade terminals, PCB mount
PCB, order code 020435-1 (see Readers
Services page)
Toroidal mains transformer, see text, e.g.,
Aixcon 230V /12-0-12 V / 200W


ANALYSIS :
-Not all parts store sells the things we need. We have to try to ask the stores that sell our requirements. We need a long time to come across as too many shops but without the requisite components are all complete.

CONCLUSION :
-We are still working on to get all the necessary components and finally succeeded.
