This week, our team focused on final integration and testing. Continuing from my work last week, I finished building the housing. After all the electronics were positioned in the box, I took measurements of the top surface to laser cut. I cut the 81 individual squares for the user to interact with the capacitive touch grid and a hole for the numpad to fit through. The laser cutter had difficulty cutting through the entire material even with multiple passes, so I ended up finishing the cut with a boxcutter.
Other than the housing, I also worked on bug fixing our software program to communicate with the MPR121s. We had been iterating and testing on a computer for some of our newer features, but once we integrated it again with our hardware, the capacitive touch grid failed to properly communicate with our Raspberry Pi. Our newer code had some changes to the behavior of the selected cell, so I had to adapt the code to allow for the touches to interact with the selected cell. I plan on working on some minor changes to game functions to improve the user experience before our final demo.
