week 2 update

Creating my To Do list:

  • organize my goals
    • Simple single cell BMS
    • Under & Over current protection
    • Fault protection
    • Step-up
    • Battery level monitoring
    • Thermistor 
    • PMIC
    • Unpluggable battery
    • One on each esp
    • Might need another for the camera
    • Mini drone batteries 
    • Run time calculations
    • Clip on, using parametrically modeled spline to facilitate batteries of different sizes.
    • Off board charging (do we really want to charge the batteries with the glasses or have a standalone charger
  • I think I’m going to do more research on existing BMS
  • I have some Onshape project the I have made in the past that I think will work well for holding the battery, they can be quickly replicated this week
  • a major thing I need to do with my team is figure out spacing for parts of the project
  • I need to set up a development environment for prototyping the code and hardware for the BMS
    • dedicated file system
    • insure access to repositorys
    • learn lab resources
    • I have a bread board to use
    • pick up esp from team
  • I need to take the boards to the lab and get an idea of the power draw.

my only concern is not really a concern, but I’m sad because I don’t think we will have a near eye display.

week 1 update

I was mostly learning about how the enterprise operates. I meet my enterprise team and got caught up in the project.
