Ingenious Dry-Erase ‘Lightboard’ for Video Lectures Allows Presenter to Face Camera While Writing

To create more engaging video lectures, Northwestern University engineering professor Michael Peshkin created Lightboard, an ingenious transparent dry-erase board that allows him to face the camera while drawing notes and diagrams in front of him. The board consists of a double pane of glass that is lit from within by LEDs. Peshkin uses fluorescent dry-erase markers which are highly visible on the lit glass. If you’re wondering how his writing is not backwards, it’s because he films his lectures through a mirror. Peshkin has posted instructions on how to make your own Lightboard.
