Work Night 12.3.19

Work Night

Date: 12.3.19

Location: Logan HS

Time: 4:30-6:00 PM

Students: Abie, Thomas, Clara, Sam and Jacob

Goal: Research both project ideas and decide on one to take to the prototype stage.

Students researched both topics and had a discussion on the merits as well as which project would give us the greatest likelihood of success. Our engineering consultant (Mr. Foye) suggested that the hydration bladder project might be a better one to do because the charging system would take a great deal of time to test and even then we may not have success.

After the decision was made to go with the hydration bladder monitoring system, students were asked to define exactly what the goals/outcomes for this project would be. Questions were form and placed in a Google doc for the next time we meet. We want to answer those questions to define the parameters of our project.

Questions:

1. What is the range of volumes we are interested in? List 6 major manufacturers with some variation in size (example: Camelbak 1-3 liter).

2. How is the "hydration bladder" used?  (We want to describe how a person will use the hydration bladder everyday use, running, hiking, military, places where water is scarce, etc...)

3. How do we want to communicate the output to the user? (Be creative here…cellphone app, monitored on the hydration bladder with a flow meter, etc...)

4. Do we need to monitor water quality? (Water quality/safety. We need to define this and what to measure or if this means incorporating a filter.)

5. Do we need to monitor water volume? (What is useful to the user?)

6. Should we include monitoring user hydration levels to see if they are hydrated?

7.  Is temperature of the water important? (What is the impact on the user in terms of preferences and health?)

8. What are some good candidates for software and hardware to help us solve this problem? (Battery powered? How often to read sensors? Is operation only on demand possible?)

Clara and Rebecca researching the problem.
