Week 18. applications and implications
Assignment
propose a final project that integrates the range of units covered, answering:
- what will it do?
- who's done what beforehand?
- what materials and components will be required?
- where will they come from?
- how much will it cost?
- what parts and systems will be made?
- what processes will be used?
- what tasks need to be completed?
- what questions need to be answered?
- what is the schedule?
- how will it be evaluated?
projects can be separate or joint but need to show individual mastery of the range of skills covered where possible, and you should make rather than buy the parts of your project
final project proposal
what will it do?
surFABoard is a surfboard with various sensors which will collect oceanographic data. Surfers can contribute to environmental monitoring by just surfing and having fun. It's a kind of an ocean version of Smart Citizen.
who's done what beforehand?
Bouys are being used to monitor ocean data.
Here and there says that oceanographers need data on shallow water conditions because bouys have been unable to measure them. Smartfin, which has been an inspiration to my final project to a great extent, is one of the solutions to the problem.
