Project Beaver Marsh: Digital Odometer

Project Beaver Marsh aims to create an innovative, fully digital odometer leveraging a CMOS chip to accurately track the movement of a rotating wheel. The device will display measured distances on 7-segment LCD screens, benefiting anyone needing to measure short linear distances. The team's progress includes initial design specifications and meetings with advisors for parts recommendations. Future plans involve further design refinement, testing, and sourcing necessary components, with ongoing concerns related to sensor compatibility and parts sourcing.
