week 14(presentation day)

Industry Day!!!
This week is industry day.Where my project will be demo to the assessor. My assesssor are Sir Ismail Bin Adam from electronics section and Sir Ahmad Sabri from Medical electronics sections.
Unfortunately,my projects is not working as I hope due to the technical problems. Thanks to my supervisor,Sir Hisham Mohd Desa because help me a lot. I am sorry because my projects is not working as do you aspect.
Thank you also to my assessor on the industry day,both of them give positive comment although my projects is not working.

On this week, I was continue for report chapter 4 and 5.In chapter 4, the result were come out and chapter 5 the conclusion.

Chapter 4(result)
Real result

figure 14.1

figure 14.2

Both picture is the result of my projects. Why not working??

Why this project is unsuccessful?

This is because the flexi sensor is not suitable to attach on the bent ruler. The properties of the flexi sensor is bent when the force were applied to it. But, before  attach on the bent ruler,the flexi sensor was bent first. So that, the range of the sensor are run out. Moreover, when I was attached the flexi force, the bent of that sensor was in maximum bent.

Why use bent ruler?

This is to get the real force that bite by mouth of the people. Moreover, to get force, the properties of the device must be hard and flexible to the mouth of people.

Chapter 5(conclusion)

This final year project “mouth assessment” is the very simple project and easy to understands. It has been designed to make the benefits to the people and the doctor as well. The people will buy this device and will bring at home and the doctor will check the data from this device and know how to treat their jaws.

Based on this whole report of this project can conclude that the main objectives were unsuccessful achieved. This project is unsuccessfully function such as it is required. The system is not complicated as it only requires the basic components for overall project. The errors occurred in the system are difficult to identify due to the unwell organized in the circuit implementation.

For the overall, one day this project will successfully done in Malaysia and will help the people that experienced injured on the mouth jaws.

week 13

On this week,I was doing poster and report for chapter 1,2 and 3

figure 13.1: poster for industry day,next week.

I put here,just the summary report for chapter 1,2 and 3.

 Summary of Chapter 1

“Mouth Assessment” is a system that can help the patient by detecting his/her force of human’s jaws. Moreover, the doctor also will know how to treat his/her patient by using this device. By using the microcontroller of Arduino had been design to process the data and display the result.

This chapter describes the background of the project. It include research about the problem we facing nowadays and how this device can solve the problem. This chapter also discusses the requirements need in completing the device.

Summary of Chapter 2

In this chapter, learned about the basic knowledge of component electronics and the types of devices electronic that can use also the application of it generally some of them also used many things in circuit electronic.

The previous project is very interesting. Although it is not exactly the same but it gives some ideas on how to start my project. This example can help in constructing circuit and testing result. But, in Malaysia does not yet this device. By the way, I was trying to do simple device to the Malaysians.

Summary of Chapter 3

The methodology is an important part to making a project becomes more efficient and extremely proper. The methods used are intended to provide an extremely good impact to the project. With this working method, the system is a way to make the project better than no method. With the flow chart and block diagram, will better understand the project and facilitate us in this project. The methods often can help us in arranging the project became better and more proper.

For the development of software state the main controller and the programming language that have been use. Before write the program, need to develop a flow chart. This is to know how the project function using the software. The break down is clear and very easy to understand, the method is simple and most importantly the step is neat and tidy.

week 12

figure 12.2: the circuit is applied to the pcb board.

figure 12.1: the sensor attach to the bent ruler

When the sensor was attached to the bent ruler and connected to the circuit of pcd board,this project are not working. May be the connection in the pcb board.

week 11

figure 11.3: flexi sensor when bent

figure 11.1: this is circuit that I was set up.Flexi sensor with arduino and LCD

figure 11.2: the flexi sensor without bent

week 10

figure 10.2: circuit flex sensor with arduino

figure 10.1; this is basic flex sensor

week 9

Activity: Create mechanism of mouth assessment!

Fisrt : Find material like iron such as ruler.
Then, make two hole like this picture(Figure 1and Figure 2).

Figure 1

Figure 2

Then,bent at the end of both side of ruler.(Figure 3)

Figure 3

The purpose of that hole is to put a screw.

Figure 4

Figure 5

But, I need more length than on these pictures.Maximum 3 inch.So, I must find it in wherever hardware shop.

One more things,I need a few spring anymore.Now I just have two spring.It is not enough for the lenght of my screw.

Figure 6: springs.

week 8

Final sensor!!!
Flexi sensor...

Figure 1 : This is flexi force.

What is flexi force??
 unique component that changes resistance when bent.

Figure 2: Flexi force can be bent.

 An un-flexed sensor has a nominal resistance of 10,000 ohms (10 K). As the flex sensor is bent in either direction the resistance gradually decreases. They convert the change in bend to electrical resistance - the more the bend, the more the resistance value.

 On MyDuino,have 2 length,those are "4.5" and "2.2" with different prices.

Figure 3: Flexi force "4.5" in length with RM65.00

Figure 4: Flexi force in length "2.2" with RM45.00

Application :
 gaming gloves, auto controls, fitness products, measuring devices, assistive technology, musical instruments, joysticks, and more.
