WEEK 22 (FYP SEM 2)          28 OCTOBER 2012  

Title : Changing to a new motor

Objective : The existed motor is being replace by the new capable one

Content / Procedure : 

The existed motor cannot run the blade smoothly as required. This due to quantity of foods that need to withstand when running the blade. The existed motor cannot withstand the weight and thus the dropping process of foods did not achieve the target. 

Analysis/ Result

Thus, the motor has been replace with the new one which is DC Geared Motor as shown below. The DC Geared Motor has high value of torque as compared to the existed one and thus can withstand the weight and when being tested, it run the blade smoothly and perfect the requirement. 

DC Geared Motor

Conclusion

As a conclusion, the high torque motor can withstand the weight better.

WEEK 21  (FYP SEM 2)            19 OCTOBER 2012

TITLE: Designing stand for the container


OBJECTIVE: To design a stand that act as base for the container


CONTENT/ PROCEDURE:

For this Pet Auto feeder, the stand is needed as to place the food container and allowing the dropping process of the foods. Besides, as the motor is being attach at the bottom of the container, the stand is needed to ensure the motor to be running smoothly.

motor attach to container

The rod attach at the motor has been modified to have the screw features in order for it to be attach to the blade. Using this way, the motor will run the blade smoothly and more efficient.

ANALYSIS/ RESULT:

The stand of the container has been design like a tripod stand. This way is chosen in order for the stand to become more balance and can withstand the weight of the container.

CONCLUSION:

When the blade is attach, the blade did not run smoothly with the motor due to the food's weight factor. Thus, I need to design a new way of dropping food to overcome this problem.

WEEK 20 (FYP SEM 2)               15 0CTOBER 2012

TITLE: Testing and Record Result of Solar Panel

OBJECTIVE: To test and measuring the Voc and Isc of Solar Panel

CONTENT/PROCEDURE:

As I am using Solar Panel for my project, I need to record the performance result of my solar panel regarding the voltage and the current measured. For my project, I am using 20Watt solar panel.

solar panel

The solar panel has been located at the field where there is maximum intensity of sunlight. The solar panel has been connected to multimeter in order to measure the voltage and current reading.

measuring voltage and current

ANALYSIS/ RESULT:

The data has been collected at different degrees starting from horizontal, 15, 30, 45, 60, 75 and vertical. For this purpose, the reading is measured from 0900 a.m to 0300 p.m. The reading at 1000 a.m as shown:

reading measured at 1000 a.m

                      
                            

CONCLUSION:

The highest reading obtained at 0100 p.m which at that time the sun expose highest sunlight intensity.

WEEK 19 (FYP SEM 2)               15 0CTOBER 2012

TITLE: Construct and Testing Solar Charger Circuit

OBJECTIVE: To construct and testing Solar Charger Circuit

CONTENT/PROCEDURE:

Solar charger circuit is one of the essential part in this project. The function of Solar Charger is to regulate the power flowing from a photovoltaic panel into rechargeable battery.Other than that, it's also help in limiting the energy supplied to the battery by the PV array when the battery becomes fully charged. It is very important as it prevent battery from overcharge or over discharge. For this solar charger circuit, I get the circuit diagram while doing some research on the internet.

Solar Charger Circuit Diagram

ANALYSIS/ RESULT:

The circuit is constructed based on the above diagram. The component involve are heat sink, circuit terminal connector, potentiometer, schottky diode, Lm317T, resistors and capacitor. The circuit constructed as shown below:

Circuit constructed

Unfortunately, as I am testing the circuit, the circuit did not functioning well. In other words, this circuit cant be used and I had to design another solar charger. I try to do some troubleshoot to this circuit and maybe it happen due to the problem while soldering the circuit.

CONCLUSION:

The remaining days is passing really fast and I must finish this solar charger matter within this week.
