Title: Design Schematic Circuit

Objective: To design the circuit by using Proteus

Progress:
                This week, I started to design the full circuit of my project. This circuit will be the guideline of what components that I will be using for this project. This circuit will contain all the small circuits that I will combine to produce the full circuit. I design the circuit using Proteus 8. This version of Proteus can interface with the Arduino board by simulation.

Conclusion: 
 By the end of this week, I finally managed to get the full circuits of my project.

Title: Project Budget.

Objective: To estimate the project costing of this project.

Progress:
                 This week, I survey the price of the components at the mudah.com and  electrical shop at Jalan Pasar. I produced a table of the main components that I will be using for this final year project 2. These main parts is the important parts of my project. The price is a little expensive but I consider this project's budget is still in budget and not over budget. Below is the list of the components and the main components that require in The Development of Portable Charger Using Wind or Water.

                

Conclusion: 
 As the conclusion, I managed to calculate the estimation of this final year project. Although I have not listed yet the other components such as the hardware to put the circuit but it  is not that expensive. So, I listed the main components first.

Title: Block Diagram

Objective: To finalize the block diagram

Progress:
                This week, I decided to finalize my block diagram of this project operation. I will be using the same block diagram as the previous semester during my final year project 1. I decided the system that I proposed during final year project 1 is good and I need to proceed with the block diagram that I have already designed.

The system of my operation starts with the LM35 to detect the temperature. The fan  will turn on when the temperature reach 31 degree celsius. After that, the peltier cell will turn on when the temperature reach 32 degree celsius. Then, the fan and the peltier cell will turn off when the temperature drop below 30 degree celsius. For the LCD, the temperature will display at the LCD.

Conclusion: 

As the conclusion, by the end of this week I finally understand the concept and operation of my project based on this block diagram.

Title: Flow Chart


Objective: To finalize the flow chart of this final year project.


Progress :
                 For this week, I need to finalize the flow chart operation of how my project's system going to work. The flow chart is the same as the flow chart I designed in the previous semester. 

Rechargeable Battery: 12v rechargeable battery are use. The battery can be charged and discharged many times. The battery act as accumulator and store energy through reverse electrochemical reaction

Peltier Cell: Thermoelectric device which can be a cooler by generating the electricity towards the Peltier. The Peltier consist of NPN semiconductor inside the Peltier and the process of heat transfer occur when the electricity are generated to it. 

Arduino Uno: This micro-controller type will read the speed of the generator based on the output given by the generator. This Arduino Uno will read the output voltage of the generator and converts it into speed of the rotor. There is some calculations for this type of method.

LCD Display: Then, The LCD display will be use to display the speed (RPM) of the rotor.

LM35: The LM35 is an integrated circuit which output voltage are perpendicular to the temperature. In addition, the temperature sensor are calibrated in degree kelvin. 

12V DC Fan: 12V DC fan that are used for the development in order to absorb all the heat and to remove the cool air which are been converted by the Peltier. The material use for the fan are plastic which can withstand a high temperature.

Conclusion: By the end of this week, I managed to design the final flow chart flow chart of this final year project. The use of this flow chart is to make sure the operation of this project can be seen clearly.

Title: Journals Revision

Objective: To do research and review on journals selected for this project

Progress:
               For this week, I review again each of the journals that I selected for the previous semester during final year project 1. The total of journals are 3 journals and 3 previous project that related to my final year project this semester. These literature review are very important because it helps me to do some more development on my project. I also used these journals to get the idea and inspiration to design my own portable cooling system. For the previous semester, I managed to go through all the journals and previous project reports but this semester, I reviewing deeper into these journals. I also consider of adding more journals to my literature review to help me with the construction of my final year project.


Conclusion: 
                    By the end of this week, I decided that the journals that I selected for the previous semester is good enough so that I can proceed with my final year project.
