How to Build a Project Light Box & Buzzer
Light boxes are light bulbs contained within an open-faced box. A screen decorated with patterns of opaque and translucent materials is fitted across the open face and illuminated by the light bulb placed behind it. Light boxes can be used to display lit signs in storefronts or for nameplates in game shows. For the use in game shows, a buzzer built into the light box may also be useful.
