Bike Computer – Build18 Project

This custom, functional bike computer was built for Build18, a weeklong hackathon at Carnegie Mellon University.

For Build18 2016, my group and I built a bike computer using the Light Blue Bean BLE microcontroller. We used a hall-effect sensor to sense a magnet mounted to the front wheel of my bike. We used this data to calculate the current speed and the distance traveled, and we then displayed this on a daylight readable screen. Two buttons were used for a basic user interface allowing for the units and the featured information (speed or distance) to be changed.

I assisted my group mates with the hardware and software of the device, but my primary role was as the designer of the enclosure for all of the electronics.
