This video gives instructions on how to build an illuminated sign. This project began in 2010 with the initial build of the sign using pllexiglas and a 2x3 frame, along with some scrap plywood and 1x2's. This video touches on the original build but shows how I converted the signs from 110v to 20 RGB modules. A total cost of $7 was spent for the conversion, making this the least expensive item used in the display.
