[More] 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 projectcreate 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 participationBecause 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 different areas as: mechanics; electronics; software; LED art; animations; demos. DescriptionBicycle 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 >> FirmwareFiRmware 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 >> SoftwareSoFtware is a PC Free Software program to send text messages and image animations to the HaRdware. See more information on SoFtware page >> [Less]

OctopusUSB offers many different Interfaces from the world of microcontroller over an easy USB interface. So you can use IO-Ports, AD Converters, I2C, RS232, SPI, CAN (opt.) easy in your own pc ... [More] application. The functions can be called in different languages (C, C++, Java, Python, ...). Because the software is a completely open source, and the components for the device simple and cheap to get, Octopus is the ideal companions for tests, handiwork or as a tool for development. Important change The pin configuration has been changed lately. [Less]
