[Blindmath] anyone heard of 3-D printing?

[Haden Pike]

We did this a few semesters ago in Electrical Engineering.  It was a great resource for helping me to understand Karnaugh maps.  I can minimize a circuit faster without one now, but it helped me to gain the insight necessary.

We have managed to use braillle to print on the diagrams to list angles and etc. It takes about an hour plus print time to create an actual image. We will be presenting our work in a few weeks with some information in the hopes that this will help someone in the future.
