We are Presenter

This is our last memory after all of us completely done our project presentation with Miss Noey. There is Mariatul Qabtiah and Nuratikah Anees from the other group, and also the another group member Sazuan Zaim and Fikri in this picture. All of us is under one supervisor which is Miss Nurul Fazlin, so that we also got a same assessor Miss Noey and Sir Razif. But sadly sir razif is not in this picture because he already leave first after he done accessing  his students. Just to say that overall of the industry day is fun and we thankful a lot once again to our supervisor Miss Nurul Fazlin, also to our assessor and other friends or anyone that had help us a lot this while. Praise to Allah, the presentation is completely done and run smoothly. 

Our FYP Assessors

There is our fyp project assessor, Miss Nurolhoda (Miss Noey) and Sir Razif. Both of them are lecturer for subject Electric Circuit in Electrical Department. The first assessor that come to our table is Sir Razif. He asked me and my partner to introduce our self and explain about our project. He asked us to see our project magazine then he asked me and my partner a few questions regarding the project schematic diagram. For an example question that he asked is the function of the IC's in the circuit, the function of the diode and so on. He also asked another question about a bridge rectifier and asking us to draw the waveform. On my opinion, he is kind of a simple person which is he does not like to make something too complicated. The reason why i am saying this because i see the way he doing his job during the presentation day. He asked me and my partner to explain about our project as simple as it. 

The same thing with miss noey. She only take a short time with us since our group is the second last group to be present. She sit and listening to our project explanation then asking us to do some demonstration about our project hardware. However since our hardware not fully function, so that she asked us to explain the reason why it happen and what is the real problem in the circuit. Since she is the electrical lecturer, so that it is very sure that she is knowledgeable about anything that relating with electrical. Before she leave us, she also give some opinion and suggestion to be improve on our project. As our thank, we give some little gift to both of the assessor. 

FYP Presentation

08 November 2012, the industry or engineering day for all Final Year students. This is the day that most of FYP candidates  feel so shacking and nervous. After almost 3 years been study in BMI, finally the final day coming. Truly to be honest, we feel very nervous waiting for the presentation day. In fact, we get Miss Nurolhoda (miss noey) and Sir Razif as our project assessors. Too much thing that need to prepare a day before the presentation. Furthermore for this semester, the presentation was start early at 9am comparing to the previous semester which is they start at 2pm at noon. 

During the presentation, me and my partner Nurul Nadiah firstly setup our table/booth first. We register for the table number 28 and 29 which is 28 is me and 29 is Nadiah. The things that we done is setup the project prototype, the project poster and do some last revision about our project circuit as a preparation for the Q&A session with assessor later. We waiting or the assessor for a few minutes until the first assessor that first come to access us is Sir Razif then followed by Miss Noey. Both of them take about 7 - 10minutes to stay at our table to asking some question and listening for our project presentation. 

Alhamdulillah and praise to Allah, finally we completely done the Final Year Project Presentation. Even though our project hardware just partly operate but we still glad and thankful because we can finish all it up. With help and guide from our supervisor Miss Nurul Fazlin, we finally manage to done it all. Last but not least, we want to thank to everyone that help and co-operate with us in order to done our project. Not forgetting to our friend name Afdal, he is the most important person that responsible to help us this while. To those who keep support and help us, a million of thanks we wish for all of you. 

Our Body Detector Prototype

Here is our Body Detector prototype, we design it as simple as that. We only using a cardboard, ribbon, baby doll, teddy bear, watch and some manics. The purpose we do this kind of prototype is to show the assessors and people that we are doing 'Body Detector', a project that dealing with a sensor to detect a presence of human body. Since our hardware itself only partly operate, so we decide to demonstrate our project by using a doll as the prototype. we put the hardware of the Body Detector against the doll with distance less than 80cm of length. Then, we put a clip at the doll body as a metal to be a input sense of the metal sensor. The concept just simple but the idea is there to be demonstrate.   

FYP Poster and Brouchers

This is our FYP poster. We used it during the FYP presentation at level 4. The important things that must we have in this poster according to our supervisor Miss Nurul Fazlin is project introduction, aim and objective, possible application, methodology, schematic diagram, result, conclusion and reference. This eight items is important since we not using any slide show to present. All the things that have written here will be the guideline for us during the presentation session. It is important to understand each thing of it, so that it will make the presentation session run smoothly. 

Before the presentation day, me and my partner already divide the tasks that we will take to presenting. So that each one of us will have for tasks to present which is me, i got task of introduction, possible application, schematic diagram and conclusion. While my partner got task aim and objective, methodology, results and reference. Since we already divide the tasks equally, so that we need to study each of it properly as the preparation. The presentation session is contribute for 30% of marks and it is important to get highest marks if we can present with well prepare. 

This is our project broucher during the FYP presentation day. We give it to our assessors and anyone that want to take it. The purpose of this broucher is to give some simple explanation regarding our project. It consist of the project hardware figure, the introduction, description, limitation, and aim and objectives also. 

Our Body Detector Hardware

 

This figure above is the prototype and hardware of our project "Body Detector". Body detector is built for the  purpose of security by detecting the presence of human body in actual distance. It detect metal that attached to the human body and metal sensor will be the input to detect the presence of human body. Our objective to built this project is to study on the possible sensors that involved in this circuit and also to develop, built and test an electronics circuit involved. The actual hardware of this project supposedly have two part of circuit board, however we changed it become one part only to make it easier to construct. Therefore, the hardware come up with the small size of casing and hardware. 

From the figure of the hardware above, you may see the design which is it look like a 'music box'. At the middle of the casing top, there is two l.e.d and one coil. The green l.e.d is function as indicator lamp which is to indicate the current flow. It will turn On once the supply is ON. The red l.e.d is function to alerting people once the metal sensor sense any human body approaching it. It will work together with buzzer, the piezo with trigger and the red l.e.d will turn ON. Meanwhile, at the middle of the casing is a coil. The coil is our metal sensor, it function to sense any metal that approaching it. Then, at the left side is the power supply battery 9v and a switch of the red l.e.d. At the right side is potentiometer 200W-500W. It function is to adjust the buzzer sensitivity. It work together with variable resistor (VR2). 

Troubleshooting Circuit

After we completely done all the hardware of the Body Detector circuit, we found that the project did not function well as what we expect the result. Even though the circuit connection seem right from outside view but we cannot find the real problem which part that did not work proper since the circuit already completely done constructing and soldering. It is hard to troubleshoot the circuit that already completely done because at this stage the circuit already combine with other parts, so that any error or signal that occur in the frequency will be quiet difficult to detect. 

Therefore, it is better if we construct the circuit first on the breadboard before directly construct it on the PCB board. The reason why it is necessary to constructing the circuit on the breadboard first because by using breadboard, we can directly check it part by part using multimeter or other tools. However if we already construct it on PCB board with complete soldering it, then it be difficult for us. First we need to suck the solder ion first, then we need to take it off one by one to check each part of the circuit. That is why we have to do the proper preliminary test and calibration before completely the complete circuit. 

For this circuit, the possible reason why it did not fully function may be because of the DIP switch that we changed. Even though supposedly the real function is once the metal sensor sense any metal approaching it, it will automatically switch On the buzzer to trigger and at the same time the red l.e.d also will turn On. However, the real function just partly operate not like what we expected for the result. We make the troubleshooting lab level 2 with the guide of the technician Abg Shahrul, however we cannot find the real problem either. So that, we just assuming that the result as partly operate only.
