Primer
This is an open hardware project based on the Michael Peshkin Lightboard from Northwestern University:
...
The project progressed through two stages where a small prototype was built to test various concepts while providing an example instructional development teams could use in designing course concepts and material.

NOTE
Thank you to all who have built a version of our design, the support and feedback has been overwhelming. It has been a while since this project was executed. We have received correspondence from several people recently saying a few of the links we refer are now discontinued. In chasing down a few of these notices, we have found that most of the items are still available and unchanged but under different model numbers that reflect cosmetic packaging differences. We encourage our community members to help. When you find a dead link and research the current component, please edit this page with the current part.
