Weekly Update: Week 9

With the deadline quickly approaching we have reached our goals that we set in the beginning of the term. As you saw in the Memorial Day update, we had a working SD card shield. We were also able to make the valve on the new bladder connect to the tube from the CO2 canister. As you can see in the following video, that the whole system is integrated and working!



Since we have a SD card we started doing some tests with the device on our bodies. We conducted several tests including walking, jogging, sprinting, and then walking and sprinting on stairs. The following video captures one of the test. Along with the video is a line graph of the acceleration data recorded.




If you compare this data to the data from the graph on the last post (Memorial Day), you can see that there is only one line instead of three. The previous graph had three lines because it was recording the x-, y-, and z-axises. The new graph only has one line because the data from the accelerometer is going through a low-pass filter first.
