Made a full list of the components needed. Searched the material for the floater.

Components list

27th August 2019

Continue to search for the floater material. A pool noodle might be suitable to be used as the floater.

28th August 2019

Searched for battery. Found lead acid battery which can be charged and can supply 12V as needed. The size and weight are suitable with the design of the system. However, the battery cannot be charged in a closed container or an airtight container. This is a big problem as the system will be placed in the ocean.

29th August 2019

Continue to search for battery and material for the top and bottom platform. An A4 sized HDPE plate might be suitable to be used as the platform as they are light but sturdy.

30th August 2019

Still have not found the right battery type for this project. Continue to search for the beacon light and materials for the magnet casing and coil casing.

Materials found:

19th August 2019

Searched and listed some of the materials needed for this project. Enameled copper wire will be used as the coil for they are used in the construction of transformers, inductors, motors, generators, electromagnets and other applications that require tight coils of insulated wire. Also searched for magnets, floater and beacon light.

Data collection for Anthropometric project at Sekolah Kebangsaan Putrajaya Presint 9 (2) and visit Edaran Marine Centre Sdn. Bhd., a marine supply store in Puchong , Selangor.

Data collection at SK Putrajaya Presint 9 (2).

Visit to Edaran Marine Sdn. Bhd.

21st August 2019

Data collection at Sekolah Kebangsaan Putrajaya Presint 9 (2) and visit Malaysian National Hydraulic Research Institute (NAHRIM).

Visit to NAHRIM.

Based on previous calculations, the number of turns of coils is unreasonable to be applied to the design. By using Neodymium magnets, this problem can be solved. Neodymium magnet is a permanent magnet made from an alloy of neodymium, iron and boron. There are many grades of neodymium magnet. The strength varies according to its grade. It is extremely stronger than industrial magnets. For example, N40 neodymium magnet has the strength of 4000T, N50 neodymium magnet is 5000T and industrial magnets are only 1T.

23rd August 2019

Made some calculations to find the number of turns of coil if N40 and N50 neodymium magnets were to be used in the system. It is proven that the number of turns of coils has decreased dramatically. Thus, proceed to searched where to purchase neodymium magnets online.

12th & 13th August 2019

14th August 2019

Did an AutoCAD drawing of the latest design and preparing PowerPoint presentation for MJIIT supervisor, Dr. Ooi Chia Yee's visit on Friday.

15th August 2019

Mock presentation with Dr. Khairi. Some additions must be made to the PowerPoint presentation.

16th August 2019

Visit by Dr. Ooi Chia Yee. Presented what the project is about and the progress so far.

5th August 2019

Progress meeting. Some  updates on the design.

6th August 2019

Made some preparations for the Anthropometic project data collection.

7th to 9th August 2019

Data collection as Sekolah Kebangsaan Putrajaya Presint 11 (2) and Sekolah Kebangsaan Putrajaya Presint 9 (2).

Data collection at SK Putrajaya Presint 11 (2)

Data collection at SK Putrajaya Presint 9 (2)

29th July 2019

Did some calculations to find induced current produced based on the target power range. Using the formula:

P = IV

Where:

P = Power (W)

I  = Current (A)

V = Voltage (V)

If the power desired is between 5W to 10W, the current will be between 416.67mA and 833.33mA.

30th July 2019

Found the approximate magnetic strength for various types of magnet and equipment.

31st July 2019

Did some calculations by varying the magnetic strength and area of coil. The magnetic strength was of a refrigerator magnet and industrial magnet. The industrial magnet has a strength of 1T. The area of coil was varied from 2cm to 4cm. It was found that to produce 12V, stronger magnet will require less number of turns. Also, if the area of coil increases, the number of turns decreases.

In addition, did some rough sketches of the design ideas of the system.

1st & 2nd August

Visit from Thailand and Indonesian partners for the anthropometric project.
