Presentation

    On Tuesday which was 25. Oct. 2011, we were having a presentation in ESE class about the electronic system. Our group which was Chin Zhi Jie, Chong Chee Hwa and me presented a topic named fiber optic. Just before the presentation, we had already prepared an article and the minute of meeting about the topic that we were going to present.
    We were nervous while presenting that day. I could see that the other groups were just as nervous as we were. Although the comments from the lecturers were not very good, I think we were doing a great job that day as I know the hardship that everyone had gone through during that week which had many test and presentation.
    Next time, I will do the presentation better and more focus on the operation of the component in the electronic system. I will GAMBATEH!!!

Practical Test

     On 24. Oct. 2011 (Monday) , our ESE class was having a practical test. The test could be said quite easy for us as everything in the test was taught by Mr.Redzuan before. All we have to do was just to memorise the colour of the code of the resistor and capacitor. The time given for the test was also enough for us to conduct the test although the instrument that required for the test was not enough.
    The test included the test for resistor, capacitor, diode and the transistor. Each of us was provided nine electronic component that consist of the component I mentioned above. I think this kind of test is good as we can remember the lesson that taught before and revised it.
    That day is actually the most suffering day I had as our class had three test in one day which were programming test (morning), ESE practical test (afternoon) and math test (night). I hope that I can score three of them with flying colour...

Transistor (Test Instrument)

Continued of Monday's Lesson


                  I was impressed by the usage of the transistor... Never thought that transistor is a multi-function electronic component before until being asked by Mr.Redzuan.

      Function of transistor

• Act as a switch
• Amplifier
• Increase/decrease current, voltage, amplitude
• General purpose
• Audio driver
• Current mirror (produce branch current)
• Filter
• Deflector

Also learned that there are two types of bipolar junction transistor) : NPN and PNP

By using digital multimeter and component analyzer, we are able to know that the emitter, base and collector of a transistor. On Monday, we also taught that how to use the oscilloscope. It is just like a TV to show the wave form that were being set in value of voltage and current.

Everything seem like piece of cake for Mr.Redzuan but I wonder that whether I can do it well and remember all the things that had been taught in the practical test. Start to worry now..... 

Diode (Test Instrument)

Fun Diode

Type of Diode:

• Rectifier diode

-Allow current to flow in one direction  only.

• Zener diode

-Stable voltage 

• LED (light transmitting diode) 

-Emitting light

    Nice Monday lesson that learn about the diode. Information above is part of the lesson that conducted by Mr.Redzuan. We all have fun  and enjoy ourselves that day especially when testing the diode by using multimeter and component analyzer. We also know about the material of the diode which are germanium and silicon. The minimum voltage which can be pass through them are differ from each other. The range of LED is 1.73V-3V. I really know about many characteristic of the diode through this workshop. FANTASTIC!!!

Recognising The Electronic Component ^ ^

     Really enjoy in this session today in ESE, taught by Mr.Redzuan. This is my first time to use the multimeter to test the electronic components. It's been a long time that I didn't touch the resistor and capacitor since the Kemahiran Hidup in Form 3. We had been taught to know the value of the resistors and capacitors too. It was a nice talk by Mr.Redzuan about the introduction of these electronic components.

    

        We also experienced the charging and discharge of the capacitors by using the power supply and the voltmeter. I thought that the capacitor is only used for charging and discharging, now I know that the capacitor can also be used to filter the disturbance in electronic system. The most interesting part today is the consequence when we connect the terminal of the capacitor wrongly during charging. It eventually explode!!! The desciption of capacitor by using water tank is really suitable as the less capacity of the capacitor, the less electricity it can store.

   
    I am looking forward the next workshop. Hopefully it will be as fun as today > <

                                                                                                                         

 

                                                    

First Workshop

   Today, we are introduced the lesson of workshop that coming soon about the multisim and ultiboard. I am so looking forward to have the class tomorrow to experience the workshop of electronic system. I feel burden too as our classes are obviosly not enough if we want to be pro in electronic system. Yet, I will try my best to follow the steps and instructions of Mr.Redzuan. According to Mr.Redzuan, our new facility in the new building seem to be some kind of awesome technology. I wish we can use the buliding as soon as possible so we all no need to rush back to campus for lesson. I need to work harder and harder to fulfil my wish to work or further study in Japan. Buck up Buck up!!!

*P/S for Mr.Redzuan: Sorry to come late in class today... Promise that no next time :(

Multisim Example:

  

Fun Learning

On 4th Oktober, I have learn about some knowledge that mean a lot to me.

I hear and I forget,

I see and I remember,

I do and I understand.

This exactly show that HOW IMPORTANT the role of practical in our life. That's why the workshop and ningen ryoku( HUMAN SKILL) are required in our course in MJIIT. We also learned that active learning is a good conduct that are needed for every student and people in order to achieve success in our life. Futhermore, the chip making video is interesting and make me more interested in ESE. I anticipate the next lesson about ESE. Hopefully I can do well in this subject and manage to get the result in flying colour. Here is the exampe video about making electronic chips.
