Taylor Holmes, Jason Partin, William Rody, Malcolm StaggGoals From Milestone 1Create an effective strap for the thermistorIntegrate all the systems with the microcontroller (Coding)Solder all systems and test themCreate a smoother, more space-efficient enclosure

Smoother, More Space Efficient Enclosure

Solar CellKXOB22-12X1Each device will have 4 solar cells.Solar Cells will be connected in series.

110mAhLi-Ion BatteryEach device will have 2 Li-Ion batteries.Batteries will be connected in parallel.

Thermistor TestingContact Not much of a problemResistance Rises Rapidly over large gap Slower over smaller gap (6 Seconds/10mV)Not affected by any likely strap materialNew Formula Approximation to find Temp

New Enclosure

Heartrate Sensor

CodingFinished interfaces to heartrate sensor, thermistor, accelerometer, LCD, and flash memoryFinished USB MSC (15MB flash drive) for storing data filesFinished USB HID for live data transferUsing this instead of Virtual COM Port for better compatibility (and no custom drivers needed)Pedometer, temperature and heartrate algorithms are basically workingAbout 99% of the microcontrollers memory currently is in use, so this has required a lot of optimizationCodingRemaining items:Finish user interface (menus, etc) on the deviceFinish computer interface to a MATLAB executableMore optimizations and cleanup to make space for any additional changesTest accuracy and performance of the sensors
