My group and I discussed three possibilities for our final project. The first is a general GPS tracker to learn more about the transit infrastructure in New York. We could develop a simple GPS module and move through the city with it, gathering location data that could then be visualized on a map. Another possibility is developing a low-cost, throw-away version in order to track things that we cannot physical be a part of.
The second idea is a randomized messaging system, wherein the user "rolls dice" or somehow uses probability to send a message to another person. If the messages were all pre-established, it could be a fun way to add unpredictability to the social text message scene.
The third idea is a goTenna-inspired project in which we try to create a way for two people to communicate off of the commercial networks. This one is less developed and would require significant hardware skills, which is why it might not be best suited to two-week timeline.
