A prelecture video can be made more engaging with a lightboard. With this method, an instructor presents material in a video while directly facing the camera and writing on a transparent screen in front of them. We present instructions for constructing an inexpensive removable desktop lightboard that can be stored as smaller pieces. We share tips for basic lightboard video editing (notably flipping the visual right-to-left) that results in visually striking, engaging videos for students, personalized by the instructor.
