Today we really started to jump into working with our mbed and IMU to start developing, in Dr. Mangharam's words: our "quick and dirty" prototype. We've collected a number of useful parts from Detkin storage already. We're using a 9-DOF IMU (inertial measurement unit) by Adafruit with an L3DG20H gyroscope for measuring hand pitch and orientation and an LSM303DLHC accelerometer/compass to measure hand acceleration. We're working on one of the LPC1768 M3 mbeds given to us in lab. Aadu also found us a couple potential bluetooth chips we can start testing with. We got a 3V LiOn batter from Dr. Mangharam to use, but we're going to need to get another to supply at least 4.5V of input power to the mbed.

We attached the mbed and IMU to one of my own, personal, swimming hand paddles. The result looks pretty sketchy, but at this point in our design process, looks are far less important than functionality.

Fun fact: the key to the Detkin office with all the extra supplies got locked inside, so we can't ask for any extra parts tonight. Tonight, we're going to focus on writing more code so that we blow everyone away on Friday. Stay tuned!
