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

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.

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.

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.
