Risks

Embedded: The biggest risk we have is that the C++ hardware interface will take a while to make; this would delay the start of writing the C++ firmware. To mitigate this risk, Melodee and Eric will write a C++ tile simulator (similar to the Python tile simulator), which should be quicker to write. It will allow Melodee to write and debug the firmware earlier.

Tile Enclosures: A risk we foresee with the tile construction is that the slight differences in tile thickness might affect the readings of the reflective sensors. We noticed that with a thicker top, the readings between black and white paper are less discrete. Originally, we were planning to sand down our wood pieces to make them less thick, but to make readings more consistent from tile to tile we might skip the sanding. That way, the differences in our sanding won’t affect our pad readings.

GUI: No forseeable risk with the GUI.

Changes

No significant changes have been made this week.

Schedule

Embedded: We added an item in the Gantt chart to refer to the hardware interface that Eric and Melodee have been working on. Everything else is relatively unchanged.

Tile Enclosures: Since we had to change our wood, the construction of our first 5 tiles are slightly delayed.

Circuits: Eric held off on buying the remaining components, because we are discussing how many tiles we ultimately want to complete (given time/budget/etc).

GUI: Aarohi had other midterms and projects last week which she accounted for in the Gantt chart, so the GUI progress is on track. She will be making a bare-metal working GUI by the end of the weekend.
