Weekly Update: Week 8

The majority of the project is complete, and only the last 10% remain. By week nine we want the device within a water proof case for testing in water. In preparation for testing in water, we have been ordering components that we deem are important.

We ordered a SD card shield over the weekend, and I arrived this week. We will use the sd card to log data from the accelerometer when it is being dropped in the water to get a better understanding of what goes on when the device is in the water. From the data, we can also try to optimize when the bladder gets inflated.

Since our original bladder was not meant to keep a person afloat, we ordered a new inflatable bladder. The bladder came in on Monday, but there was some bad news. Not only was it a bit small but it also had 3 different valves for air intake. This would not be feasible. Therefore we ordered a new inflatable bladder. We ordered a new inflatable bladder, ones that are used during snorkeling. It's inexpensive and effective. It is pictured below:
