The LightBoard project was developed to assist faculty using whiteboards for drawings and demonstrations who had the need to capture the information for short video lectures. While lightboards are currently commercially available and plans for construction posted online, these designs are expensive and time consuming to produce. A low-cost, rapidly deployable, lightboard was needed to simplify the capture of sketches, notes, and equations to support on-demand video content.
Using the baseline design created under a Creative Commons license by Peshkin (2013), a portable, low-cost, easily assembled lightboard was conceptualized and tested for creating lectures for online biology courses. They were successfully piloted in two online biology courses. The Radlab created three prototypes. The first one was made with glass, was heavy, and expensive. The second prototype used acrylic for the screen which reduced both weight and cost. The third and final prototype incorporated the changes made in the second one and added larger tires and wheels for easier transport across campus. The original prototype is in biology, the second one is in the Health Sciences Library and the final version is in Harper and available for faculty and staff.
The lightboard consists of a metal frame containing clips designed and made on a 3D printer. The clips encase LED light strips. Additional 3D printed material was used to create a tray to hold the fluorescent markers that are used on the lightboard. The lights highlight the text and drawings from the markers. With the clear screen, the presenter can be recorded facing the audience, the video flipped for correct orientation and the videos placed on BlueCast or embedded in courses hosted on BlueLine.
