Worknight 1.28.2020

Logan InvenTeam Worknight
Date: 1.28.2020
Location: Logan HS
Students: Sam, Abie, Clara and Tommy
Goal(s)
1. Decide on t-shirts (name) Hydration Bladder Monitoring System
2. Software- work on new Bluetooth modules
3. Hardware- Hydration bladder water volume and measurements - Measurement strategy and manometer introduction.
4. Create a list for ordering any new parts/components we need for the next meeting.
5. Wrap up

Discussion topics on future direction:

System Theory- Use basic physics principles, experimental data, and software/logic AI to make a reasonably intelligent, and reasonably reliable system. Need logic capability and non-volatile memory
Functional-Sam/Software/ Processor Hardware

• Startup and software development system
• A/D operation
• Wireless communication/Bluetooth
• Wire communication/display
• At his point don't be concerned with power conservation
• Water volume calibration routine and software operating logic
• Intermittent data and results
• Calculation of water volume remaining

Team Functional and Hardware Work
• Hydration bladder water volume and measurements
• Measurement strategy
• Sensor operation and calibration (pressure measurement- manometer)
• Explore differential bladder measurement, vertical position only

Outline software operation logic
• Perform careful calibration to develop form of data for software interpretation
• Refine software logic
• Team- develop AI algorithm for software interpretation.
• Implement and demonstrate.

Work Night 1.21.2020

Date: 1.21.20
Location: Logan High School
TIme: 4:30-6:30 PM
Goal: Decide parts to order, collect data on hydration bladder flow rate.
Students: Tommy, Abie, Clara, Sam, Rebecca, Ella


Today we talked about what parts we need to order and looked at a couple of sensors that have been purchased already.

We decided to focus on one size of hydration bladder, a 3 liter one. This helped us figure out what hydration bladders to purchase. We are going to get two 3 Liter Camelbaks, one male edition and one female, and then one smaller bladder. A spreadsheet was made to record data from the experiments we started tonight. Using a hydration bladder we already have, we started experimenting with different water measurements. These measurements will help guide next week’s work night. We also looked at possible t-shirt designs.

Summary:
Collected data
Pressure changes on volume of water in the hydration bladder
May need to look at the data more to interpret it better, establish connections
Working on software component, bluetooth connection
Made a rough decision on t-shirt designs
