Overview of Status of Analysis, Design, Fabrication, Tests, etc.

We cannot recognize the dead plankton in image processing, working with SIO to see if it is within the scope of our system
Primary goals completed: test object controlled in test fluid
Improving error by implementing integral control
Can recognize small fragment of plastic balls
Demonstrate at SIO

Accomplishments from Previous Week

Goals for Next Week (list names after each item). Use specific and measurable objectives.

Make smaller, non-sphere objects from HDPE to use since actual plankton may not be feasible with our camera/system
Lasercamm the diffuser
Reduce controller error
Update simulation of flow
Finish Poster
Finish Final Report Draft
If time permits, obtain larger organisms from Jessica (~0.5 - 1mm) to test since plankton are not working well
Recalibrate pump

Use CNC to machine the diffuser
- Not possible according to Ion. This is because the CNC machine constantly pushes the drill bit. Drill bits are highly likely to break considering its extremely small size(0.75mm diameter).
Laser Cut diffuser
