Switch Project: 1st Iteration
A switch which is embedded into a running jacket will enable a GPS tracking device that passively tracks a users distance. Once connected, an LED will turn on as a feedback loop so the user knows the device is working. Enables easier activation of a GPS system for runners as opposed to carrying a phone and programming a tracking application. After a run is complete, the user will plug the GPS tracker into their computer for analyzation.
After hearing feedback from the class on the mock-up of the running jacket, I made some design changes prior to construction of the first iteration.The most significant change is the placement of the button that is attached to the slim piece of fabric (which also acts as a reminder). Originally it was affixed at the bottom and in order the turn on the switch, the button would cross the zipper, however this posed an issue because it interfered with unzipping the jacket.

In order to keep the ‘reminder’ aspect of the button, but without having it interfere with the zipper, I chose to place the connecting button inside the jacket just below the chest. This will not interfere with any other functionality of the jacket and still accomplish the task of turning on the GPS accompanied with LED feedback. Below are some sketches of this process.

I documented the process of constructing the first iteration. Materials used were conductive string, a 3V battery holder, Velcro, and an LED light board.
