Week 25

Title: Final Assembly for the Project.

Objective:

1. Complete the project to be ready to present.
2. To make sure everything going to work without problem.

Method:

1. Assemble the hardware and the circuit.

Result:

Conclusion:

After all the hardware and circuit is assemble, the product still can produce the output and produce the energy.

Week 24

Title: Assemble hardware and Piezoelectric.

Objective:

1. Completing the staircase structure.
2. Place the piezoelectric at the hardware.

Method:

1. Place the cover to make the staircase look nice.
2. Solder the connection and place the piezoelectric at the staircase.

Result:

Conclusion:

The staircase structure and piezoelectric connection are done and ready to use.

Week 23

Title: Construction of the Staircase

Objective:

1. To build the staircase that stable and able to stand a person.
2. Able to place the piezoelectric disc

Method:

1. Find the suitable material at the hardware shop.
2. Design and construct the staircase.

Result:

Staircase structure and plywood for the base.

It can withstand the maximum weight of the person around 75kg.

Conclusion:

The staircase is construct carefully and hardly so pedestrian can step on it.

Week 22

Title:  Circuit Construction for Energy Harvesting Circuit and step-up voltage circuit.

Objective:

1. To make sure the circuit working smoothly
2. To detect any problem occur.

Method:

1. Solder the circuit into donut board.
2. Testing the circuit.

Result:

The energy harvest circuit is construct by using the circuit diagram provided from the data sheet.
http://www.linear.com/docs/28909

Conclusion:

The circuit is working properly and it give the output of 3.5V, and its the same value with last testing procedure.

Week 21

Title: Testing Piezoelectric with IC (LTC3588).

Objective:

1. To measure the output from piezoelectric.
2. Stabilized the output for further use,

Method:

1. Connect the pieze-disc by soldering to the piezoelectric.
2. From the piezoelectric, make a connection to IC (LTC3588).
3. Measure the output with multimeter.

Result:

The result show in the video.

Conclusion:

The output from the piezoelectric through the IC is 3.5V and its stable.

Week 20

Title: Soldering the Energy Harvest IC on PCB board.

Objective:

1. Solder on PCB for protection to IC.
2. Prevent the IC from damage.

Method:

1. Find shop that can solder IC that use blower.

Result:

Before the IC solder to PCB.

After the IC has been solder to PCB.

Soldering is completed.

Conclusion:

By completing the solder of energy harvest circuit (LTC3588) IC, next testing with piezoelectric can be done for next stage of the project.

Week 19

Title: Meeting With Supervisor to Show List of Hardware

Objective:

1. To get confirmation about suitable material to buy.
2.  To discuss the material need to use in the project 

Method:

1. Show the specification of the hardware based on the project needs.
2. Show all hardware listing to supervisor that need in your FYP project.

Result:

List of item:
1. Piezoelectric (20pieces)

2. Plywood

3. Steel (L-design)

4. Energy Harvesting Circuit.

5. Step-up voltage circuit

Conclusion:

By listing the component that need to buy, the project can start to be build for first stage.
