Following are the most recent design ideas and other sketches.
In the last meeting it was thought to use gyroscope sensor with a main board to trigger three seperate set of lights (left turn, brake, right turn). Device willl be usedby tilting the head to different directions (front for brake, left and right for turns). This interaction is still to be tested but it suits the conditions of a cyclist in theory and it would contribute to the ridicilous themeof the overall design.
Hardware for the setup is still in the research process. I will order soon when the optimal setup is decided.
