Project Description

Working Title: BikeSpace

Goal: A bicycle mounted computer sensor system to detect and log the motion and proximty of passing and nearby vehicles.

Technology

  1. LV-MaxSonar-EZ4 Ultrasonic Range Finders
    Product page and datasheet
  2. Freeduino USB Host Boards

    schematic
  3. Android 2.3.4 powered handsets
    Nexus S, HTC G2/Vision w/CyanogenMod 7.1
  4. bicycles, roads and cars
    lots of these in the world

Software

  1. Project code repository and issue tracker
    Android git repo
    Arduino git repo
  2. Android SDK & ADK

Notes, issues, etc.

  • The writer of the Arduino playground document claims analog input from the MaxSonar sensors is less accurate than pulse width
  • Someone claimed that for the analog output from the sensor noise can be reduced with a capacitor and resistor, I'll have to find the details again though if needed.
