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.

WEEK 18 (FYP SEM 2 )             2 SEPTEMBER 2012

TITLE: Feeder circuit

OBJECTIVE: Designing Feeder circuit

CONTENT / PROCEDURE:

Feeder circuit is the main role in this project. It control the operation of the whole project. I still in designing my feeder circuit. As for now, I has some problem regarding the programming. I now working for C++ programming. For the alarm setting, after undergo a few meeting with my fellow programming lecturer, Sir Tan, he suggest me to use timer interrupt. The program is still under discussion.

ANALYSIS / RESULT :

As for the circuit, it not being construct yet. I bought some component regarding this feeder circuit. At first I trying to construct a simple timer circuit using 555 IC but still it does not finish yet. For another feeder circuit which using real clock display on LCD, it still under discussion as it need detail wiring and I still on researching. But of course, the basic component that it have are: diode, Led, LCD, capacitor, voltage regulator, resistor, mini slide switch, IC, buzzer, button and so on. 

simple timer circuit using 555 IC which 50% finish

CONCLUSION :

I hope I can finish this within this few weeks and thus can start running the whole program as soon as possible.

WEEK 17 ( FYP SEM 2)              2 SEPTEMBER 2012

TITLE: Blade for the feeder

OBJECTIVE: To design the blade for the feeder

CONTENT/ PROCEDURE:

In this project, the blade play the significant role to drop the food. The design of the blade must withstand the weight of the amount of foods. Besides, the timing of the blades to move need detail attention as it will result the overall operation of the feeder. At first, I design the blades by using perspex as shown below, but then it broke into pieces.

RESULT/ ANALYSIS:

So, as for now, I choose to design a blade using plastic pipes as shown below. It has screw on each end of the blade which can be use to adjust the balance of the blade. For now, the blades move pretty fast when supply being fed to the motor, thus, I need to setting the timing of the motor to ensure the blade moves like desire.

CONCLUSION: 

As conclusion, the blades needs details design construction and programming to ensure it moving smoothly.

WEEK 16 (FYP SEM 2)             1 SEPTEMBER 2012

TITLE : DC Motor design

OBJECTIVE : To design a holder for DC motor

CONTENT / PROCEDURE:

For my project, I had buy a DC motor 92H with maximum voltage 24V and  high torque which can withstand some weights. In my project, this DC motor will be attach together with the blade under the container. In order to ensure the motor will move the blade smoothly, it must be grip and deeper attention is needed to handle this problem.

motor need a holder

RESULT / ANALYSIS:

As for now, the holder for the motor need to be done by welding it to the base of the container like shown below.  But then, its not finalize yet as the design is still being discuss as I am working to create the stand for the project.

the holder design for now

CONCLUSION:

I hope I will finish this matter as soon as possible as there a lots of things to be done regarding the project.

WEEK 15 (FYP SEM 2)                  1 SEPTEMBER 2012

TITLE     : Buck Converter

OBJECTIVE : Designing a buck converter 12V to 5V

CONTENT / PROCEDURE:

From Wikipedia, a buck converter is a step-down DC to DC converter. For my project, I need a 12V to 5V DC Converter as the circuit for my feeder operate with 5V while the supply being fed is 12V. 

RESULT/ ANALYSIS:

Before building the circuit, I had run a simulation of the circuit using multisim software. The result come out really suit well.

simulation of 12V to 5V buck inverter

After the simulation has provide the result, I then proceed in constructing the circuit. Like in simulation, the circuit is functioning well.

12V to 5V converter

CONCLUSION: 

Alhamdulilah, this circuit run perfectly. The supply after being step down can be use to run my feeder circuit.

WEEK 14 (FYP SEM 2)                         29 AUGUST 2012

TITLE : Project hardware design

OBJECTIVE : To design and implement project hardware design

CONTENT/ PROCEDURE : 

For the cat food container, I have been decide to use the usual food container in plastic material. There are two of them which one is used to store food and other used to place the blade for food dropping purpose.The container is carved ¼ from it base.

RESULT / ANALYSIS :

The food store in the first container will fill the space of the container within the blade which locate in second container. When motor is running, the food within the blade will be drop off through second container.

the containers with food and blade

CONCLUSION: 

For this purpose, the upgrade design of blades is needed in order to ensure it can move the foods. The above container need to be grip to ensure the blade did not affected by the foods weight above it.

WEEK 13                                               20 APRIL 2012

TITLE: Presentation is over, ALHAMDULILAH

OBJECTIVE: Improve project

CONTENT/PROCEDURE:

The scariest day of this semester was end.Alhamdulilah, all praise to ALLAH, I satisfied with my presentation except for some small matters. Both of my accessor give their comment and suggestion regarding my project. One of the comment is to replace the step down transformer with other devices as step down transformer normally use for AC voltage.  

RESULT/ANALYSIS:

This is my full slides presentation :

CONCLUSION: 

 Marks has been released, alhamdulilah
