Bike Buddy – sonic bike computer
Bike Buddy is a bike computer that uses sound to generate its data. Made using minimal components, Bike Buddy uses a simple contact mic that plugs directly into your phone for maximum convenience. All data processing and display is then done with a custom Android app.
The code for the app is on github: https://github.com/arathorn593/Bike-Buddy
