How (analog) traffic lights work

Craft & Design

MAKE subscriber Joe Kerman sent us a link to this video about how mechanical controllers for traffic lights work. This is from a Canadian kid’s TV show from the late 80s (I think), called the Acme School of Stuff. I watched a number of other episodes on YouTube and found them pretty engaging and educational. [Thanks, Joe!]
