WEEK 11


Title:
Final Year Project briefing. 



Objective:
To gain knowledge from the briefing.



Contents / Procedures: 
For this week, there is Final Year Project briefing at TTL 1. The committee is Dr  Mohd Khairil bin Rahmat and Mr Shamsul Zahari bin Shahidin. Some point of the briefing is on the T-Shirt, claiming budget and submission of the report for FYP Sem 2 and Diploma students. Plus, to reminds the students on the presentation day for Degree Sem 1 and Engineers Day for Degree Sem 2 and Diploma students.

WEEK 9

Title: Troubleshooting all circuit


Objectives:
To analyse the circuit performance.


Content / Procedure:
All circuit have been  brazing.
Do a component test. Collect an old component that have been used in order to reduce a cost.
Try to do some test towards circuit to analyse the performance.


Result and Analysis:
Have some circuit have problem because of some component burn or damage.

WEEK 8

Title: Construct the circuit.


Objectives: 
> To make a circuit PCB etching and drilling.
> To Test a PCB Inverter circuit.
> To analyse the circuit performance.


Content / Procedure: 
> Prepare a material to do circuit etching.
> Do a component test. Collect an old component that have been used in order to reduce a cost.
> Try to do some test towards etching circuit to analyse the performance.


Result and Analysis:
I'm done a construction for  High Current Inverter Circuit. The circuit is fly-back converter and using 555 timers as an controller.
This testing part was done by using my old equipments that have been used during my studies.
The circuit PCB design and the pictures during etching the inverter circuit.

WEEK 7


Title:
Final Year Project briefing and further research relay.




Objective:
To gain knowledge from the briefing.
To search the related information of the relay.




Contents / Procedures:
For this week, there is Final Year Project briefing at TTL 1. The committee is Dr  Mohd Khairil bin Rahmat and Mr Shamsul Zahari bin Shahidin. Some point of the briefing is on the T-Shirt, claiming budget and submission of the report for FYP Sem 2 and Degree students. Plus, to reminds the students on the presentation day for Degree Sem 1 and Engineers Day for Degree Sem 2 and Degree students.
Internet research has been done in order to know more on the relay.






Results:
Relay







Relay is an electrically operated switch. Many relays use an electromagnet to operate a switching mechanism mechanically, but other operating principles are also used.
Relays are used where it is necessary to control a circuit by a low power signal or where several circuits must be controlled by one signal.
Current flowing through the coil of the relay creates a magnetic field which attracts a lever and changes the switch contacts. The coil current can be on and off so relays have two switch positions.
The coil of a relay can passes a relatively large current, typically 30mA for a 12V relay, but it can be as much as 100mA for relays designed to operate from lower voltages.
Relays are usually SPDT or DPDT
