~Week 14~ Industrial Day

This week was very important week for FYP students because we need to present our projects and the assessor need to judge us. During that time, we feel so nervous because a lot of criteria assessor that have been shown up. Our assessor was En Azlan and Pn. Nulida which is FYP coordinator. 

When we shown up to the hall, we set up the booth with our poster. Besides that, we also test our project while waiting for the assessor to come. When we testing the project, sometime it functional well and sometime it not accurate. We become more nervous and pray to Allah that everything will work well when the assessor test our project. 

Alhamdulillah, thank to Allah that we manage to present our project well and the project function perfectly. When the assessor announce then first winner of fyp project for diploma student, we was do not believed what the assessor announce because the first winner was us. We are very thankful to Allah for giving us the moment that we wont forget in our life. We would also like to thank to our supervisor which is Pn. Norhaslinawati Binti Ramli that have guide us and give a lot of motivation while doing this project. However, do not forget to our family and friends that have given us a lot of support and motivation during making this project. Finally, thank also to our reader that frequently visit this blog and we love you so much. muahhhh <3 

~Week 13~ Poster

In this week, we need to prepare poster for our industrial day. We need to gather the information what need to put into the poster. We also check what the best suitable theme for our poster that related to our product. Beside that, we also meet Pn. Norhaslinawati which is our supervisor to check our poster detail. Finally, after she check and agreed with our poster, we print out the poster and save it for industrial day. 

InsyaAllah we are going to do our best for Industrial Day ^_^

~Week 12~ FYP Briefing and Draft Report

This week, we need to attend the FYP briefing at TTL so we can get the information about incoming event which is Industrial Day. Beside that, we also be informed that we need to prepare draft for our final year project report. We also need to prepare the report immediately because the due date for draft report in week 15.

~Week 11~ Casing and Prototype Installation

After all of our circuit is completely functional. we install the casing and prototype to our product. We keep find idea and survey from internet how to make our prototype looked. Finally, we manage to think the best idea for our prototype.

(Prototype Installation)

This week, we also testing if either our circuit functional in prototype or not. We hope the circuit will work on prototype. 

~Week 10~ Combined with GPS tracker

After troubleshooting and our circuit completely functional. we combined our transmitter with GPS tracker. We also need to test our GPS tracker if it functional or not.

~Week 8-9~ Troubleshooting Circuit

In week 8, we troubleshooting the circuit because our circuit do not function at all. We trying our best to study the circuit and finally we manage to solve buzzer receiver circuit which  before this it not sound at all but after the troubleshooting we manage to make it sound. However, we did not manage to solve another problem which is transmitter and receiver signal. The receiver still make a sound when near the transmitter. In week 9, we refer to lecturer and technician to guide us solve this problem. Finally, after referring to them, we manage to solve this problem.

~Week 7~ Construct Transmitter And Receiver

"Transmitter"

The circuit diagram for a single transmitter units is shown below, current is the supply to the circuit from a 3V "coin" cell B1, via on/off switch S2 and diode D1. The diode provide reverse polarity protection.

It is best to use the specific schottky device which introduce a smaller forward voltage drop, and therefore loss, then a conventional silicon diode(0.2V rather than 0.7V approximately). Capacitors C2 provide a small reverse of energy and prevent the supply voltage from fluctuating. This stabilises the operation. 

A low power 7555 timer, IC1, is setup in a standard astable (pulse generator) configuration while switched on, this produces a continues train of on-off pulses at its output, pin 3. 

This Choice of resistor R1, R2 and Capacitors C1 provides one pulse per second for one of transmitter (Unit A) and one pulse every 1.2 second for the other one (unit B). In fact, the timing are slightly longer but it help to consider them as above. 

Beside that, The on time are much longer than the off one in each case. The purpose of these will be explained presently. 

(Transmitter Schematic Diagram)

"Receiver"

The complete circuit for the receiver section is shown below. This draw approximately 3mA, so a most substantial battery pack is needed than for transmitter. While the buzzer WD1 is sounding, the current rises to sound 6mA. 

The battery pack use in the prototype consist of four AAA size alkaline cell. If AA size cell could be accommodated inside the case, these would provide a doubling of operation time.

~Week 6~ Survey and Buy Component

In week, 6 we went to jalan pasar to survey component that needed for our project. We also survey the best price for our component. We also buy component from internet. Below is the list picture of our component:

~Week 5~ Find Information About IC

In week 5, we search the information about our Integrated Circuit(IC) Datasheet through internet. Below is the picture of our Datasheet. We use IC HT12E 18 pin, HT12F 18 pin, and NE7555 Low Power Timer 8 pin.

~Week 4~  !!Planning Schedule for our Final Year project!!

       

~Week 3~

Mass media often report crimes such as snatch thefts often happen in our country lately .Snatch that often, so is a crime that is shocking for our community. The frequency of this crime proves that there is something wrong in our society today. The mass media describe the various factors that led to this incident together measure to deal with it but the amount of thefts continues to rise year by year teenagers are the main pillars of the country in the future, thus rise and fall of nations will be determined by the youth of today. However, adolescents who were supposed to be at school has been involved in various criminal activities such as murder, robbery, drug abuse and so forth. This phenomenon is alarming everyone because it can hinder the country's aspiration to produce human capital that has the credibility and responsibility for the country in the future. Thus, a variety of factors that cause adolescents fall into the mire of crime. 

However we come solution with our project Development Smart Security System From Snatch Thief to prevent this problem.The Project consists of two type approval transmitter unit and a receiver. If either transmitter becomes separated from the receiver, a buzzer in the latter part will sound. The receiver is fitted with a switch to allow the use of only one transmitter if required. This system was originally designed as a two channel child alarm (to protect either a single child or two children at the same time) but many other application springs to mind. For example, one transmitter could be placed inside a briefcase and another in a coat pocket. If the user forgot to pick up either of these items and walked away, the buzzer would sound in the receiver. The receiver must be carried on the person in a way that would make it practically impossible to lose it. This could be done using a belt clip, for example. Beside that, it will not be possible to use this system if either the transmitter or receiver where placed inside metal containers or if there were substantial metallic “screening” objects between them.
