This is a video from one of my favorite publications, Make Magazine. In it, host Bre Pettis joins up with a hardware hacker to create a circuit using an LCD display and a GPS system. They first show the coding and creation of the LCD screen to make it say whatever you’d like, and then they move into integrating it with the GPS unit. The video shows clear directions on how to do this, as well as an application of the finished hardware.
