Today is our last workshop for ESE in this semester and we has lectured by Dr. Kamal. Dr. Kamal show us a slide show about our next semester's one subject which is Analog and Diginal Signal. Digital Signal is contributed by binary number. It can store the information of analog signal into binary number then make the analog signal can be transfered far away. Then some electronic device convert the binary number information of the digital signal into analog signal again make other people can get the information wherever the person is.
Go back to the slide showed by Dr.Kamal, the slide has a video i think is get from YouTude make us more easily to understand. The video had said that the digital signal is based on logic level. It is represented by the voltage ranges representib '0' and '1'. 1 is represent the circuit is close and 0 is represent the circuit is open. 1 and 0 can represent all the information since binary number can be any length. More information will need more longer binary number to store it.
Then, Dr.Kamal assign 2 paper to each of us. The first paper is binary number exercise. For this exercise, I can do the addition and subtraction of binary number by just add and minus the 2 binary numbers to a binary number without define the upper and below binary number into decimal number first to find the answer in decimal number. I found the method to do in this binary numbers exercise.
The second paper is communication code worksheet. Finally, we can solve the problem by leading og Dr. Kamal. Then, we are finished our first semester ESE subject. I write the self evaluation form in high mark because I feel that I have learned so much of skills in this subhect. Thank you.^^

ESE COURSE IN 19 DEC 2011
Finish our mini project, we had a lecture about electric today. First, we devide to 2 person 1 group. Then we get from En. Redzuan the fluorescent light tube, wires, plug, and toolkit. We learn how to make a plug extension and how to install the fluorescent light.
Then, En. Redzuan show us the methods to do the above said. He explain all the method clearly and show us also some wrong method to aware us where is the student always will do wrongly, especially the positive and negative end and electric short checking. After he built the two things, he supply electric current to test the two things and surely has success.
Then we start to do with our partner in a time interval because it will be calculated as mark of this subject. I with my partner Jeffler divide the work to do it faster. We complete the extension first. Then we make the fluorescent light tube. After this when we try the light, it works. Then we try the extension, it cannot function. Finally found the mistake is the screw is not tight enough.
After that we appreciate to En. Redzuan because he is teach us a lot. And tomorrow is our last lecture for ESE.

ESE COURSE IN 13 DEC 2011
Today, we continue the mini project. We need to bring toolkit and soldering apparatus come to workshop lab. We start our lecture early at 8:30am because we want to finish our mini project today. When we arrive the workshop lab, we just continue our soldering without any lecture.
Some people already do the soldering in KSJ. I'm also, but still do not complete yet. I look the sample again to make sure my soldering is not wrong. The soldering need the experience to do it. Why I say like this? This is because I slowly know how to soldering well that may be because of I already got the experience yesterday and I have mentioned somewhere that I need to be careful.
Then, some people already finish their circuit but I still not complete. They go test their circuit by using power supply and some have success. But some of them are fail because their LED is not coruscate. After two hour I also complete my circuit. I go to test it and it is work. I feel so sastified after do this all.
Then, I write my name on the circuit board and pass up to En. Redzuan. We return back the toolkit and the soldering apparatus. We clean up the table. One of my friend still do not have finished his circuit board, so we wait for him. Meanwhile, we talk a lot of crabs. After he finished his circuit and pass up, we go to other lecture.^^
ESE COURSE IN 12 DEC 2011
Already long time we do not have ESE lecture. This is because the public holday and factory visiting last week. This make our ESE lecture is lacking of time to complete it. What I heard from my friends from session 2, they already complete their mini project. But, my class just want to begin our mini project today.
In the beginning of the lecture, En. Redzuan show us a slide show about how to prepare a board. Actually this slide show En. Redzuan already showed us before, so I tell my friends about this problem, but my friends say it is okay, do not need to tell. So, I just keep quite and see the slide show again. I was found that something small information I already forget. It is good for us review again the slide show.
After see the slide show, we go to take our toolkit and soldering apparatus. We also need to bring our components to do this mini project. En. Redzuan assigns the original board to us. We use tape to stick the transparent circuit draft on the board. We be careful to stick the plastic because it make the tracks of the circuit. After that, we exposed the board to UV light for 90 seconds. And then, we take out the board and clean it by using sodium solution and acid. This is the dangerous step because acis is corrosive. Then, I take the board to be cutted by using a cutter to make the board in a suitable size. Then, I drill the holes for through hole components.
Then, En. Redzuan show us how to solder components on the board. He also make some sample for us to follow the sample to do. I take out the components and look on the schematic paper to know where are the correct position of components. After I totally understand the position, I begin to solder. I am very carefully because I know a bit fault will make my circuit board mulfunction.
It take a long time for us to do the soldering. We spend a lot of time until we already exceed the ESE lecture time which should end on 5pm, but we do until 5:45pm. Then, En. Redzuan tell us to tidy up the table. We bring the components, toolkit and soldering apparatus back to KSJ. We will continue our mini project tomorrow morning.

VISIT TO CANON OPTO MALAYSIA IN 6 DEC 2011
Today my course SMJE go to visit Canon Opto Malaysia sdn bhd at Shah Alam. We have arrived Canon Opto Malaysia at 9:00 am. After that, we take a course’s photograph with Canon factory as background.
Then, we are invited to a room. We listen a talk about safety in workplace. The lecturer tell us about the safety method that practised in Canon company. The most important thing is the fire alarm and the route to escape from the factory when the workplace fire is occur.
After that, there is a lecture about the history of Canon. We look a slide show which contain a video that tell the information of Canon. I can know that Canon is begin from early of 20th century. This company is begin by a brothers who learned the optic precision science. I am also surprice that the photocopy is invented by Canon. I can see also the film technology is replaced by digital technology.
After that, we go to see the production process of the camera. First, we need to wear a shoe plastic to reduce the dust. This because a dust in a len can be a very large shadow on the screen to take picture. We also have go through a way that blow off the dust on our body. Then, we can the production process. There are many section to admnistrate the worker to produce camera. What I can see is a production need many robotic machine to make the production time faster and make more profit. The robotic machine is based our course electronic system to build it up and can do the process that human cannot do. For example, machine can solder the component that very very small and fast. Human is cannot do it accurately and fast.
The circuit of the camera is designed by Japanese engineering. The technology of Japanese is so high level and they do not share with Malaysia partner. The worker just follow the instruction and test the camera by machine. I can see a camera can be fast to built when I walking straight. The worker is already very expert to do the process because they are already trained. I think the communication between workers is essential to reduce the conflict. In a company, tolerance is very important to complete a work more efficient. Not just company, a country also very need tolerance.
I can see also there are a lot diagram to tell some information about safety way, introduction to the camera and some perfomance chart. Canon company encourage the worker to be do the work faster. When a worker is do fastest, the chart on the board will show his/her name to praise him/her. This can make the production more better in quality.
After that, we go to visit the lens production section. In this section, we can just see a few things only since we cannot go more far and deep to see the production. In this section, the technology is more based on machanic. However, there are still have many robotic machine to do the process. Then, we have a lunch at the cafeteria in Canon company.
Then, we have a Q&A section for give chance for us to more understanding the process to make camera. After that, we atart to go back to KSJ by bus.
I can a production of a camera need a lot of technology, especially electronic system. This is the most important part in a camera. Japanese engineer have this knowledge and make their technology and science is more higher level. I hope in one day, we Malaysian can also make a camera with out brand that can compete to foreign country.^_^

ESE COURSE IN 29 NOV 2011
We begin to start our project today. Before start the class, En. Redzuan want me and my friends Zhi Jie, Chin Yap go to MJIIT office. We need to bring various of equipments such as wires, light tube, and a box of components from MJIIT office.
When we bring to worshop lab, there are already have some equipments on every students' tables. We put down the things we carry. On out table have a tool kit, multimeter, and a bettery. Everything are new things. Now each student have their own multimeter, don't need to share the multimeter like before.
We set up the multimeter by put the bettery inside the multimeter. The toolkit inside has various of apparatus, such as screw driver.
Then, En. Redzuan show us how to begin the project. First we need to learn how to make a new board. There is a lot of steps to do to make a new board. En. Redzuan show us a slide show that teach us the steps. We have to prints a blue print of circuit schematic, then exposed to UV light, clean the unused chemical composition on the board's surface.
After that, En. Redzuan give us the components and want us to keep these all ourself. We return back the toolkit and multimeter to En. Redzuan.
I so excited to begin our proiect. I need to wait for a week to do the project in next week. There must a lot of skill can learned from this project.^^

ESE COURSE IN 22 NOV 2011
Today, we have a test for multiboard and ultiboard. Firstly, En. Redzuan give us a test paper. The test paper contain the schematic diagram of two circuit. En. Redzuan explain to us what the question ask about. Then, our test is started.
We open the multiboard to draw the two circuit diagram. When I do the test, I found there are something very hard to do. The most difficult thing is En. Redzuan want our traces must be 40 mil. This is very difficult, because before that we never try to change the size of traces. When I enlarge the traces, there will occur a lot of problem. The traces will overlap.
Even though I try to fixed the problem, I still cannot find the cause of the problem. The computer also is not very good and always be hang. En. Redzuan tell us to press the escape key. When the test is time is up, I still cannot overcome the problem, so I just pass up my saved file.
Actually, I already very lucky because some of my friends, their computer is suddenly shut down and they did not save their file. So, they cannot pass up their work.
What I feel after test is my face very ‘warm’ that may be because of I very focus on the test and the test is very hard.
ESE COURSE IN 21 NOV 2011
Today, En. Redzuan continue to teach us about Ultiboard. En.Redzuan teach how to change the size of the traces and pad. We also learn how to change the position of the components and the traces.
The Ultiboard got a switch that can let the computer to find the best way to route the traces which is called autoroute. This will make us more easy to the work even though I just simply place the component on the board, but the computer still can find the route.
What I about tha Ultiboard is this is a software that make the work more easy to complete. Now, I already know actually what we can learn from the engineering course of university, the most important is software using skill.
For example, when we learn about mathematic, we can use scientific calculator. When we want to design a circuit, we can use Pspice of Multisim. When we want to design a shape, we can use Autocad. So, in university we are exposed to these all thing. What the thing that common people cannot become engineering, just because they do not know these all software.
For me, before I learn multisim, I cannot imagine how to build up a television or just simple electronic device. Now, with these all software, I feel that is no more so terrible difficult to design a circuit. I love my course very much.

ESE COURSE IN 15 NOV 2011
Today, we continue to learn multisim. The electonic circuit tha that haven't done yesterday we continue draw it at the begin of the class. But because of many people do not saved the drawed circuit, so En. Redzuan want us to do a new circiut by using multisim.
The new circuit has two IC so I feel it is more complicated to draw it. En.Redzuan also mentioned us the different of electronic and electric.

After this, En.Redzuan tell us so many funcrion switches at the right handed side of the Multisim window. There are multimeter, oscilloscope, function generator and many otherelse. This all features have 3D look, just like the real apparatus. This software designer is very good guy because he design this software by insert a lot real things that make me feel this software is interest and funny.
Then we learn about Ultiboard. First we need to make all the component that we had contributed becomes real. Because the component that we draw has two types which are real and virtual. After that, we can transfer all the component to ultiboard. In Ultiboard, we have to design the shape of the board first. Some was design a Mickeymouse shape , robot shape, animal shape. My one is a round circle shape with some different size of circle hole. And then we can the component on the board in 3D view. I can rotate the board in all direction.
For the ultiboard, we just can learn a little bit only because lack of time. I am vey excited for the coming ultiboard lesson.
ESE COURSE IN 14 NOV 2011
Today, we has the first lesson to the workshop.Before begin of the class, we need to tick the survey which states the condition of our study. First we learn the software which called Multisim. This sotware help the user to analys their designed circuit. En. Redzuan tell us the history of the Multiasim. Multisim have alot of version. Now is already version 11.The version thaat we can from the computer in the lab is version 10.
After that, En. Redzuan tell us the switches on the multisim. First we learn how to insert the component inside the shematic. When we switch to insert components, we can choose many typesof components. There has diode, basic, transistor, mixed and so on. En. Redzuan give a shematic graf of a circuit and then want us to draw it. Sometime it is so difficult to find the wanted component. En. Redzuan us a lot to find the components.
After we draw th circuit, we can test the circuit function or not. Just click run, then the LED on the circuit will ligthed. The most interest thing is that when we connect the LED with a high voltage, the LED will burnt out. This software is funny.
We also draw a new circuit which contain a buzzer. When we click run, the component will give out sound of the buzzer. We can also adjust the frequency of the buzzer, when we set high frequency, the computer give a high tune.
A lot of things can learn from ESE course. I feel interesting.

Today, the new lecturer teaching us. His name is En. Rasli. He show us a powerpoint slide about of electronic compounds. We are exposed to a lot of things. First, we see about OLED(Organic Ligth Emitting Diode). It is future technology which can bended because it is flexible. And also can be cut a piece of it, the remaining screen of OLED still can function.
We also see about FPGA.Its full sentence is field programmable gate array. It is RAM based and programmable. It can applied on digital signal processing, software-defined radio and so on.
Then, there is slide about power electronics. It is combinationengineers between power and electronics. It is concerns in power level rathan than signal level. PE component have a ot of types. For e.g. SCR, BJT, GTO, IGBT, JFET, and otherelse. It can be applied in many sector like residental, commersial, industrial, transportation, utility system and else.
The last electronic component introduced todayis IC chips. It can minimize the number of electronic component in a electric circuit.
I hope that later En. Rasli will teach us more detailed about these all electronic components.tq^^

Today we have lab test that has take mark of our this course mark. We were divided into 3 types of test to make sure we can not copy other person answer. First, we have to prepared our apparatus. After that, we need to wait for the test begin.
Then, we were called out to take the electronics components. We need to use the apparatus like multimeter, component analyser, and data sheet to test the electronic components. We need to write down all the properties of the components into our answer paper.
We have take a long time to done this lab test. Actually, this all things I have do it before but when I testing, I will found that something Ihave already forget. So, I need to try to remember the prosedure. Even though, this is test, but I feel interesting also^^

ESE COURSE IN 18 OCT 2011
Today we learned about transistor and integrated circuit (IC). The function of transistor are as a switch, amplifier, deflector and so on.We have learned transistor have two types which are PNP and NPN. We also learned how to find out the different pin of transistor which are base, emmiter, and collector by using multimeter and component analyser.Then we learn about IC. En.Redzuan show some modem of computer to show us the IC. We can find the first pin of the IC by see the appearence on the surface of th IC.
Then we also learn how to use function generator and oscilloscope. This is very interesting since we can make a lot of types of wave. We can make zigzag wave, rectangle wave and sine wave. We also can control the frequency, wavelength, zoom of the wave. En. Redzuan also teach us some formula about wave. These formula is needed when we are using function generator. I waiting for the day we can actually use the function generator to do project>_<
ESE COURSE IN 17 OCT 2011
The electronic component what we learn is diode. Diode has many types which are ligth emitting diode(LED)and zener and so on. Diode has many function. For example, diode can make sure the direction of the current flow. Diode can also be emitting light by using LED.
We have learned how to use apparatus to test the diode. We also learned how to diffretiate the positive and negative pin of diode. En. Redzuan also show how the number that we can see on daily life like elevator that tell you which floor are you is make up by diode. This number function diode is called 7 segment diode which composed by 8 diodes. It has a common cathode or anode and the other pin are opposite charge pin.

ESE COURSE IN 11 OCT 2011
Today we learn about some electronic components. First, we learn about resistors which is the most simple one electronic component. The resistor has the colour code to determine its resistance. The first bond is the first number and the second bond is for second number, The third one is the multiplier and the fourth is the tolerance. We also learn how to use mutimeter to determine the resistance of a resistor.
The second electronic component we learn is capacitor. There are different types of capacitor and the shapes of the capacitors are different. Some has colour code, some is flat and some is cylinder shape. We have learn how to determine the capacitance of different capacitors.
En. Redzuan also tell us the capacitor cannot be charge in reversed pin. He has showed us by charging reversely a transistor. A few seconds later, the transistor was exploded. Somes fumes was come out and smelly. This is so dangerous if we don't differentiate the component rigthly^^
ESE COURSE IN 10 OCT 2011
This is the first day we attend to the ESE workshop. Actually, first day will only introduce about learning outcome by En.Redzuan. We also discuss about the planning of ESE workshop in whole year. In this year, we will learn 4 section of the ESE. First, we will exposed to electronic component, test instrument, practical test. Then, we will learn about PCB by using software multisim and ultiboard. Then, got a mini project to do. And the last is the electrical application.
After that, we are given to back more early. I need to prepared myself for the future learning of the ESE. Hope I can study well^^

ESE COURSE IN 4 oct 2011
First, Dr. Kamal is talk about how to use application in the forum. Before that, we had advised to send our blog post link to the forum, but everyone cannot do this. We also discuss about the topic of oral presentation for the application of electronic system.
After that, Dr. Kamal also show us some video about electronic system engineering. The video that talked about semiconductor is most interesting. Silica that make sand is the important material to build up the semiconductor.
I also expert for the next lecture of electronic system engineering.

ESE COURSE IN 27 SEP 2011
Today we learn a lot of things. We had talk about the essence of belief that are faith, workshop, monetary affairs, social conduct, and good conduct. Thenwe were asked about learn to serve or learn to earn.In my opinion, I think that I am learning for serve because we as people, we are serve to each other. This is call one for all, all for one.
After that, we have such a question:In your opinion, why and how good conduct is related to electronic system?
After that, we have such a question:In your opinion, why and how good conduct is related to electronic system?
· In present time
· Future time
· Everydaly life
So, I think that good conduct is very important when we are using the electronic system. The power of science is used to heip people. We should not using electronic in such evil thing just like weapon. In everyday life, people should use electronic properly.For engineer, they should create electronic system in good conduct.Don't be cheating, use cheap and unsuitable material to make electronics.Good conduct in electronic is needed for protect people life and should be maintain untill future.

Introduction To Electronic System Engineering
Last wednesday is the first day we learn the ESE lesson. We had look some youtude video about Japanese language learning. Gen ki des ka? Gen ki des. Dr. Kamal was showed a slide that about electronic system.That was a lot of information that I can get. For example, all product of electronic is begin from a simple electric ligth bulb circuit . I was admired that last time people was having the mind that electric science can change the world. I also interest in the video that talk about study style.
