Raspberry Pi trail signs

Question

As a biker, I have noticed that many people do not realize that trails are often split into sections for pedestrians and bikers. Many people put others in danger by straying onto the wrong trail without warning, and causing accidents. What if there were electronic signs that warned of oncoming bikers or pedestrians so others could get out of the way in time. There is no "dominant race" on the trail, but there are some simple rules of ettiquete that could be helped along by this simple device. I suggest an led matrix and an infrared sensing system powered by a Raspberry Pi. Any suggestions?

3dprinterwannabe The more I think about this project the better it feels/sounds. I would take the suggestion made by Dimitios and investigate Arduino. It would be an excellent project to introduce you to Microcontrollers, Sensors, LED Matrixes, Wireless communication, Solar power and power management. If you have access to a 3d printer you could print an enclosure to house the components. The finished product could be tie wrapped to a gate post and operate autonomously. I would take Michaels comments onboard, and design the unit in such a way that it doesn't turn the countryside into a disco. This project could easily be broken down in to a series of small challenges that will eventually come together as a finished product. If you would like some help, myself and the rest of the community would be more than willing to assist you
