  • Things we liked this year:
    • Zero to a close to functioning IMU 
    • Messed around with lots of sensors
  • Things we want to change next year:
    • Better organization
    • general coherience of a sensing subteam 
  • Things we feel need to change next year:
    • Sensing needs to happen
  • Random Ideas:
  • IMU:
    • Function: Accelerometer, Gyroscope, 6 Axis Sensor
    • Inputs: BMI 088 (current sensor being used) 
    • Outputs: movements and rotations in 6 degrees of freedom; I2C or SPI 
    • Left to implement: Code
    • Needs to be positioned very close to COM

Talk with Lucky (Adi & Lucky 6/11/19):

  • Things we liked this year:
    • Strategy - Hoppe's idea for how we assembled the wiring harness
      • We had a lot of extra length
      • We didn't sleeve the wires together before cutting and crimping
        • Issues with sleeving are junctions, we aren't good at that
        • We always ran the sleeve too far to the end of the wires, we struggled to get the right length without putting strain on wires
        • A method of sleeving we can do is use wire wraps
    • Less tension for wiring on the cars - lots of extra length on ampseals, especially in LV box
    • Great use of Busmaster - get it up and running with CAN address space earlier
      • Make sure everyone knows how to use it
  • Things we want to improve next year:
    • We have to read the rules this year
      • Really hurt us the last couple of years
      • Submit rules clarification for everything we don't understand
    • Figure out whats going on with BSPD ground short detection
      • We never fixed it, but bypassed it
    • Fix onboarding
      • Issues: majority of people are put in a position beyond their ability
        • They're responsible for something critical
        • It's fine, but in the past we haven't had enough people to help out
        • People have to have a greater working knowledge (usually only the electrical lead)
    • We need to make the overall system design - high level to low level
      • It needs to be more of a collaborative process than it has in the past
    • Change the way we interact with people when we're in a position of mentoring/teaching/being in charge
      • Get rid of condescending tone - maybe not intentional, but not a good attitude
      • Usually happens when we catch someone else's mistake
  • Random Ideas:
    • We didn't consider something for the AIR control board know we were charging the accumulator 
    • Since the AIR control board can sense the final shutdown voltage - we can detect that on air control instead of on bspd (faster)
      • The existing circuitry already can do this
    • Rather not have all the little dashboard stuff in the front
      • Put enclosures on the side in a panel
      • Figure out a way to have the dashboard have a robust way to connect into some wires
    • We have to put a spot on the Master switch panel for the BSPD test switch
    • Include MC fault, etc. 
      • We can find waterproof super low current switches to use
    • Find some drop in sensing solution to use on MKIV - Urgent
  • Advice:
    • No matter how much you think you can manage on your own, you'll do better with the help of others
      • Don't be afraid to ask for help
    • Move together when making early design decisions - keep everyone on board
    • Go to all mechanical design reviews
      • Ideally, everyone goes to design reviews
    • Kickoff meetings won't understand everything at the beginning, but it's good for them to see that process
    • Never cut corners - things can still work even if they're ratchet. Don't fall into laziness
      • Everything, even as simple as a crimp, should be held to the highest standard
    • Follow Hoppe's example for making everything a good as it can be
    • Go through the PCB design checklist religiously 
    • Fall back on others at times of low energy
    • Tell people how they can be helpful
