Lightboard Transparent Dry-Erase Board: Show & Tell

 |  |  |  |  |  |  November 27, 2013


The advent of cheap cameras and free online streaming services means teachers can stream or even pre-record their lessons so students can watch them at their own pace and even in advance. But using conventional blackboards or whiteboards means the teacher is often facing away from the camera. That’s why Prof. Michael Peshkin of Northwestern University made the Lightboard.

The Lightboard is a 4 x 8 ft. pane of architectural glass lit by 8 ft. strips of white LEDs at the top and bottom of the frame. The transparent board lets Prof. Peshkin write and look at the camera at the same time. He uses fluorescent markers and a black background to make his notes and sketches more vivid. He also uses the board to superimpose images from a projector.

When he’s recording his lessons, Prof. Peshkin shoots himself and the board through a mirror to correct the orientation of his notes and sketches.
