Build Log

Week of January 8, 2024

Planning

  • Questions for first meeting:
    • Create a separate page for build log?
    • Power source during capstone symposium?
  • Tasks for everyone
    • Adrian: frontend + mobile (ios OR android)
    • Adam: backend + desktop (windows)
    • Cameron: embedded (NFC)
    • Jonah: build door (machining, 3D printing, power management)
    • Allen: assembly + testing of handle and integrated systems (electrical + mechanical)
  • Machine handle (by first week of february)
  • 3D printing enclosure, a lot of the internal components
    • SLA or SLS

Week of January 15, 2024

Hardware

  • Finalized CAD and BOM for the lock (@AllenZhang2989)
  • Started manufacturing and procurement of parts (@AllenZhang2989)
  • Test door designed and constructed (@jonahbelman)
    • Next steps are to route out cavities for lock faceplate and strike/power in

Software

Embedded

  • Experimented with I2C protocol for PN532 (@CameronKinsella)
  • Discovered the PN532 breakout board is unresponsive with both primary communication protocols (@CameronKinsella)

Week of January 22, 2024

Hardware

Software

  • Implement table & modal functionality for frontend admin dashboard (@AdrianJendo in #3, #4. #5)

Embedded
