surFABoard is a citizen science platform that gathers oceanographic data to monitor the ocean health.
Here is a brief description of my final project.
I designed a 3d model of a surfboard in week 3 and machined styrofoam in week 8.
After removing tabs and sanding the surface, I applied a cloth (Jute) and a resin (two-part epoxy resin) onto the top and bottom surface of it. I also installed finboxes at the bottom of the board.
I installed fins which I designed and made in week 10.
I glued LED strips on both surfboard rails with a waterproof silicone sealant in final development.
microcontroller board: Junino (satshakit)
sd card module
K-type thermocouple converter module
power supply board
interconnection universal board for MISO and SCK, and a simple voltage divider (5.0 V to 3.3 V) for logic input of GPS module.
wirings
I put it in an enclosure and connect all wirings including wiring from a surfboard through a tube.
I walked around my Lab, and I confirmed that temperature and GPS location data was logged in an SD card as comma-separated values (.csv) successfully.
I opened the CSV file with google spreadsheet, then uploaded GPS data (latitude and longitude) to GPSVisualizer to draw my GPS data.
I think I've achieved my evaluation criteria for my final project.
