Making Holes in the Board Book

A project log for Notable Board Books

How alert and happy my mother (with Alzheimer's) became when she heard familiar songs! Lift the book, turn the page--the book does the rest.

Making clean holes in the correct spot for the photoresistors can be a challenge. I 3d printed a "punch jig" to make this process a bit easier. First, line up the the punch jig with the upper right corner of the page to be drilled.

Use a drill punch to mark the place for the hole.

Use hollow core drill bits to create the hole.

I had to gently start the hole with a normal drill bit, then use the hollow core bit. 

The first hole goes through five pages, the second through four etc.
