This project involves creating a Persistence Of Vision (POV) device for mounting on a bike wheel. There are a few of these devices already on the market (and we've bought a couple to experiment with); this project differs in that it combines a basic bike meter with the POV readout. The device will display speed and total distance travelled. Unlike standard bike computers, this information isn't displayed for the cyclist but broadcast to other people in the street. By making this information public we give the cyclist's activities greater 'visibility' within the urban environment.
The project will be built from open source resources based around the Arduino microprocessor.
The project is documented in the following pages:
- Trial of Bike POV devices
- Moving to the Arduino
- Adding a Sensor
- Counting Revolutions
- Storing Data
- Conserving Power
- Doubling the LEDs
- Designing an Enclosure
- Using an LED array
- POV Resources
