Our design closely resembles a standard swim paddle with holes for surgical tubing to keep the hand in place. We added many of these for maximal customization. The four smaller holes will be where we screw our electronic shield onto the underside of the paddle. Tomorrow, we will be designing this shield for our components that we will be 3d printing out of high density polymer material.
We kept fighting with bluetooth today. In short, we've learned that Bluetooth is really annoying. We've tried working with about 4 different chips now and only one even pairs successfully with our MacBooks. The one that pairs (Bluefruit EZ Key HID) is really buggy and disconnects very easily. We have a feeling it has something to do with the baud rate and how our serial ports are set up. We'll explore this more tomorrow as well.
Getting our gyroscope to work is a task we've been working on in parallel with everything else because all the code is in Arduino... again.
We're still waiting on our pressure sensor, flash RAM breakout, and coin cell battery breakouts to come in, but we did get all of our water proofing supplies and surgical tubing in today!
Hopefully, in the next week, we'll have a semi-working device that we can start water testing with. Stay tuned!
