Baseline Demo Recap

Demoed our baseline dry prototype today and we only had a few small hiccups. Our current shield configuration is very hard to connect to the external buttons and LEDs because there isn't much space in the shield for extra wires and the short wires from the lid essentially require us to connect everything to the mbed upside down. Also, because our paddle pulls so much current with the bluetooth and SD card reader, our LiPo batteries kept dying in relatively short amounts of time. We think they weren't fully charged before the demo though. They have a current rating of 1000mAh so we should have about 5 hours of charge for fully charged LiPos.

Our reach goals for next Wednesday/Thursday:

• Use machine learning and data analysis tools to identify catch, pull, and recovery within the stroke - information that could be used for swimmers to make better sense of their individual acceleration curves.
• Refine our vibration actuation so that the feedback is meaningful for the swimmer.
• Incorporate waterproof pressure sensor data.

Super reach goal:

• Inductive (wireless) charging!
