I spent this week working some on the physical holder for the dev boards/handle attachment. I worked on making a new design that is more user friendly. I made it have a better fit so that it doesn’t move around on the handle. This allowed us to collect data without needing to use tape to secure our dev boards to the racket. The dev boards are currently just hot glued onto the 3d printed part, this is working much better than the previous method which was sub-par double sided tape. Next I will begin working on a design that does not need to use hot glue and instead just has mounting holes and press fit solutions. I have begun testing this in parts (fit holds for the IMU dev board), but there is still additional work to be done on this. I expect to finish this next week. I also worked on making visualizations of the swing path. I wrote some code using matplot lib that visualized the IMU movement in a 3d graph. I also spent a bit of time getting the battery to work, I wrote some simple code that reads out the battery voltage level and also had to change the pins in the battery header as they were incorrect.
My progress is on schedule, but the data collection needs to be moving at a faster rate. We were able to collect some initial data, but need to spend more time collecting data so we can train our model.
Next week I hope to finish the physical holder for the dev boards and also start looking into bare component & PCB fab.
