In this video we reverse engineer a mechanical sign from 1985 and lean how to get it working again. The radar unit it was designed to work with no longer exist so we will interface it with an Arduino. Along the way we learn about CMOS digital logic and how the books by Don Lancaster were used to create our modern digital world.
