Our team worked on finalizing our proposal (slides) and ironing out the schedule for the upcoming weeks. In doing so, we saw that some of the significant risks for our timeline include delays in getting our PCB back from fabrication. In addition, delays in getting our microcontroller and other hardware components could significantly impact our progress. From a design perspective, the PCB, 3D printing, and user interface don’t pose immediate risks. However, our choice of microcontroller (Daisy Seed) could prove to be a risk as none of us have previously used it (in contrast to other microcontrollers like STM32 or Raspberry PI). Our preliminary research indicates that this risk should be minimal, but our contingency plans involve using an FPGA or microcontroller from the school inventory that meets the specs that we desire.
Our decision to go with the Daisy was the only design “change” that we made over the past 1-2 weeks. This “change” was more of a narrowing of our options to a singular implementation. No changes in cost are to be accounted for as purchases have not been made.
The initial schedule was finalized this week. The schedule will be updated as needed in future status reports.
Our group looks to wrap up the research phase of our project and begin making order requests in the next few weeks.
