Hey Ben I think a good project to build/sell would be a raspberry pi gps system for automotive situations because I would like to have the video go to a separate screen (for example a tft screen in the visor) I would love to watch the project be built and it would help people that don't want things left in the open like a gps module attached to the window because I would like to keep things looking stock but have the sneekey gps system I would love it if you could respond back to me
