I built the brachiograph a few years ago. I wanted to show my kids (8 years old and 6 years old) cool things the could build by plugging a raspberry, some servos and readily available materials. We were impressed on how good we could reproduce one of those shopping mall cartoons of my daughter. It was a fun build.

What were the most challenging parts, and what kinds of problems did you run into and have to resolve?
