Work Night 12.17.19

Work Night

Date: 12.17.19
Location: Logan HS
Time: 4:30-6:30 PM
Students: Clara, Abie, Tommy, Sam and Ella
Goal: a) Facilitate discussion on solutions to the hydration bladder monitor problem.
b) Begin to create an organizational diagram to assign jobs responsibilities for the project. 

Tonight we discussed possible job responsibilities and who might want to do what on the InvenTeam. We began to define some of them below:

Sustainability Lead (dual role)
Software Team -Sam B.
Hardware Team
Engineering Design (Inventor)
Project Manager (Dual Role)
Public Relations/Finance- Ella L.

We also discussed the t-shirt design and possible project name. We decided we needed more time to work on these so for now the name stays as hydration bladder monitoring system. Mr Foye then facilitated a discussion on the experimental platform and will work on possible sensors that we can use. We spent the last 45 min. getting a equipment ready for a bench test using an Arduino Uno. Students tested potentiometers to see if they can vary voltage levels to simulate sensor input on the Arduino.

Notes from our discussion are below:

Design consideration

-        Volume

-        Weight

Measured with sensor

Pressure is candidate to measure

Optical height

Measure strain on hydration bladder

            Strain gage measuring system

Measure water volume, temp, water quality, flow

Be consistent with voltages

Need a paragraph to describe how data outputs will function.

Contact Austin Sather about code from last year

Cell phone app/watch

Pros:

-        App could be more user friendly

Cons:

-        More work/time to do watch and app and is it convenient to check your cell phone when hiking and running.

-    

Does there need to be user input? On/off switch and do we need a beginning volume measurement?

Which measuring system? Relative or absolute or incremental

-        Weight or containment volume – most accurate

Current tasks:

Clara: Write user scenario paragraphs

Sam: List of software functions and display functions

Abie, Clara, Tommy started working on the breadboard

Tommy: Flow sensor application and mounting location

Future tasks:

-        Selecting sensors

-        Mounting locations and containers for electronics

General task

-        Volume measurement strategy

Group Task: name ideas, visuals, t shirts, slogan/marketing line

Team members working on getting potentiometers ready for breadboard.

Clara soldering a wire on a potentiometer.
