Test 2

   On 22/11, our class was having the test 2 of the ESE. It was all about the lesson that Mr.Redzuan taught about which were multisim and ultiboard.
  
   After giving the test paper and some briefly instruction, we then tried our best to do the multisim and ultiboard in th computer for 2 hours.

   After struggling in the multisim and ultiboard very hard, I submitted the products to Mr.Redzuan. Hopefully I can get a good result for them...

Ultiboard (continue)

       Back to the ultiboard lesson today. Today we learned more about the design of our circuit in the ultiboard.
      
       After we put the electrical component in all around of our board, we learned that it is not enough. We have to arrange our components. The autoroute function in the ultiboard allowed it to find the suitable way or route for the components to connect to each other. When the yellow line appeared, it show that the position of the component we put is not suitable and have to arrange it to other place.

      After all the route is complete, then it will show all green line, means the route is ok already. Then, we also had been taught to play around the position of the route and components, whether to decide it to be top of the board or bottom of the board. We also can lock the route up , so then the route will not being move when we move the components to other place of the board.

     Next, the properties of the routes that represent the wire that have to be connected can also being adjusted such as changing the width of the wire. But, if we do that, there will be a problem too. As the wire become thick, the wire designed on the board will overlap if two or more of the wire are close together and it need to be adjusted again.

    Besides that, we also learned pac and jumper in the design of our board. The hole for the component to be inserted which known as pac have to be large enough to being soldered. If not, the solder will mix to another pac that close to the previous one and whole of the circuit will be ruined.

    Furthermore, we also can design the name of our board on the board to make it nicer. The size, width and type of the word can be adjusted easily.

    Lastly, the board that had been completed have to be printed out. We had been taught to see the preview of our board in 2D before we print out the board. Here, we can list out the page that need to be print and seperate them in different papers.

    Before we were going back, we also watched the video about the match of the robots. It is so interesting that I almost wish to design my own robot now after watched the video.

   I wish I have the good luck and good memory  for the test tomorrow. Hopefully it will be not so difficult...

Multisim 2

      Continued our lesson of yesterday, we were also doing multisim for today. We were asked to do more circuit design for today and Mr Redzuan trained us to do in a faster way.

     After that, Mr Redzuan also taught us to use the instruments given in the bar on the top of the multisim program which include multimeter, oscilloscope, measurement probe, agilent multimeter, agilent oscilloscope, function generator and others. By using these kind of instruments, we were able to measure the value of the voltage, current, resistance and others of different electrical components existed in the circuit easily. Also, we were also can get the waveform by using the oscilloscope and adjust the frequency of the voltage source to see different kind of waveform. They are just like the real instruments and it is very convenient when using them to design a circuit.

   Next, after we played around the multisim, we also had been taught to transfer the circuit that had been designed to the ultiboard. In the previous lesson, we only had been taught to transfer the circuit designed to the ultiboard and looked them in a 3D way. Today I just realised that we need to arrange the component and connect it first before we transfered them to the board!! But due to lack of time today, we were not able to do that today...

   For the ultiboard part, we had been taught that how to design our board. By clicking the function on the top of the ultiboard program, we managed to play around the shape of our board and how to make a hole on the board. The components that had been transfered also can be dragged and placed anywhere on the board. But, we need to make sure our board designed is a complete board and not a seperate board. Otherwise, the wire cannot connect the components together.

   That's all I learnt for today. Very satisfied and thanks to Mr Redzuan. Looking forward the next class!!

Multisim

     Today, Mr Redzuan taught us for three hours again in the afternoon like the plan go on. Our class had learned an important thing in electronic system which is multisim. We are lucky that we have the multisim software in the computer provided in the workshop. Although I have little disappointed when Mr Redzuan mentioned that the audio system was not prepared in the computer, but later we can get the sound while simulate the circuit in the multisim.

    Besides that, we also had been taught to find the components in the multisim software and design the circuit. And very sorry that I am dozing off while Mr Redzuan was giving the talk about the multisim as it is very tired to have the class in the afternoon and I am not enough sleep in the field trip too...

   However, when we were told to practise to design the circuit as shown, luckily I managed to complete the work that asked by Mr Redzuan and not feel so tired anymore. I guess that I am not a good listener but probably can be a good practitioner.

   The ultiboard that manage to see the circuit designed in multisim in 3D is also very awesome! Also, the buzzer that make the sound is also very fun. The pitch of sound is getting higher when the frequency of buzzer become higher. In short, it is a good lesson for today >.<

Ex for multisim:


P/S:  Mr Redzuan, thanks for the sweet ^ ^

Lesson by Mr. Rasli

   On 1/11 (Tuesday), we have the first lesson taught by Mr. Rasli. The information shared by Mr.Rasli with all of us was fantastic!
   We had learned about power electronic is a combination engineers between power and electronics. It concern in power level rather than signal level. It also divided into many fields such as solid style physic, electronic theory, electronics, power systems, electronic machines, stimulation and computing and the others. In addition, the PE components had been taught by Mr. Rasli. For example diodes, SCR, BJT, GTO, IGBT, FET, JFET, UJT and the others.
    Next, OLED is also a part of lesson that attracted me a lot. The OLED stands for Organic Light Emitting Diode. Here is the structure of OLED.

    We also learned FPGA that is Field Programmable Gate Array. It contains large digital designs and compile the logic using software to create binary file, then download it.
    PE application is also introduced by Mr.Rasli. Now, we know that PE can be used in several categories such as in residential area, commercial, industrial, transportation, utility system, aerospace, telecommunication,  electro-technical application and the others.
   We also learned that IC which means integrated circuit is a huge of discrete elements that are compressed in one single chip of silicon.
