Overview of Status of Analysis, Design, Fabrication, Tests, etc.
We presented our clock mechanism to our sponsor and explained the major challenges we were encountering with this design, namely the Gear ratio
We have abandoned the mechanical clock due to the impracticality of the design
We have begun more in depth research on Electrical components: including microprocessors, actuators, timing crystals, batteries.
We are narrowing designs for programming the device (aka encoder vs. potentiometer vs. buttons
Researching how to design a rotary and linear seal (Parker)
Accomplishments from Previous Week
Constructed balance wheel that could oscillate
Decided to move forward with electrical design
Created simple arduino circuit that could count time.
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Continue electrical alternative analysis; determine components that would be necessary for a microprocessor + timing crystal design (Alan, Denis, Calvin)
Order electrical components to build circuit (Alan, Denis, Calvin)
Create CAD of Rotary Seal and / or Linear seal (David, Colin)
Determine programming Interface of Device (David, Colin)
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments
The Sponsor did not have many comments, but he agreed with our conclusion to move forward with the electrical design after we should him of Proof of Concept Prototypes.
The Sponsor also gave us documents that outline how he has timed electronically in the past
Instructor Comments from Last Meeting and Actions Taken to Address these Comments
Start building the Electrical Proof of concept as soon as possible
We created a simple arduino timing circuit and are in the process of choosing the specific electrical components we will need.
Risks and Areas of Concern
Power management of the electrical system. We need to have the device be able to last a season ~100 uses or it needs to be rechargeable.
Programming of the Device that is quick and simple enough to satisfy the fisherman’s demands
Resources or Information Required but not Available
Schedule
Determine the specific electrical components we will need and ordering them as soon as possible, ideally by Wednesday of Week 6.
Design all seals and order O-rings by Friday Week 6
Budget (list amount spent and amount remaining)
Plastic Gears for gear train: $6.99
Metal rods for gear train: $7.99
Amount remaining: $4,271.03
Progress on Report and Webpage
Completed the First Draft of the Report and Webpage
