Elderly Asset Tracker

I realized after watching my semifinalist video that it was difficult to see the phone screen which displayed truncated GPS coordinates, I have provided a screenshot of my text messages for reference.

GitHub repository has been updated with the most up to date firmware, as displayed in the semi finalist video.

I spent some time of the last few weeks learning SketchUp and have designed a simple case to house EAT. The case has cutouts for antennas (not necessary but doesn't hurt and saves on material), USB and battery connectors, as well as the speaker and microphone. There is enough space in the case to hold a 1Ah lithium ion battery. A loop is made on one side of the case to allow for a lanyard to be attached so the user can wear the device around their neck, .stl files can be found in the GitHub repository. The case has been printed by Shapeways and is currently in transit, cost was approximately $18 for both pieces.

TI wrote a blog post on my project!
