Hi everyone. I'm new to the open source development world and am not even sure where to start. I have some background in electronics and design, but it has been many years since I even attempted to do design anything. I actually have something I'd like to design for personal use, and after suggesting it to a few friends, they'd like one as well. So I figured I'd start my research and if things work out well, maybe even bring it to market.
Any suggestions on how to proceed? Good tutorials? My project is a car mp3 player, using a laptop HDD or flash memory with a few more additions if possible.
