Introduction
Bicycle LED POV is an electronic LED bar to attach on bicycle wheels. When riding the bicycle, the LED bar will draw with light, text messages and image animations.
Custom text messages and animations will be drawn on a PC software and downloaded using an USB cable.
Goals of the project
- create a Free/Open hardware, firmware and software LED POV for bicycle wheels;
- easy to use for non electronics technician people;
- find some company that wants to sell PCBs, kits or final assembled product;
- use only Free Software tools as possible, like CAD software for PCB design, C compiler for MCU firmware, etc;
- open to improvements and new ideas from community.
Your participation
Because hacking is fun and projects are like life, always evolving, If you have any ideas, If you think you can improve the project, If you want to say something, please leave a message on the discussion group. This project is a work in progress, It's an effort to improve actual bicycle LED POVs as the SpokePOV from Ladyada. There is room for a lot of improvements as the project involves a few different areas as:
- mechanics;
- electronics;
- software;
- visual LED art;
- art animation.
Description
Bicycle LED POV is an electronic LED bar to attach on bicycle wheels. A magnet is also attached on a fixed part of the bicycle (as example, the fork), so the hall effect sensor mounted on the Bicycle LED POV can detect each full rotation of the wheel.
Bicycle LED POV consist of mainly three different parts: Hardware; Software and Firmware.
Hardware
HaRdware consist of an electronics printed circuit board with LEDs and a few components as a microcontroller unit, a memory to hold the text messages and image animations, an USB connector and 2 NiMh cells.
See more information on HaRdware page >>
Firmware
FiRmware is the software that will be inside the MCU, it will configure the hardware system to work as needed.
See more information on FiRmware page >>
Software
SoFtware is a PC Free Software program to send text messages and image animations to the HaRdware.
