braile swivel pin ruler! (Incomplete)

pinshape

This is an unfinished ruler that features a swivel gauge mechanism. As you slide the gauge along the ruler's length, it triggers pins that pop up over each inch. This allows users to read measurements in braille. Unfortunately, this project has been a challenge, and I'm forced to leave it incomplete for now. Maybe someone else can pick up where I left off and finish the job, making these rulers available to everyone who needs them.
