Clement Wong: Motivational Sign

My final project is a three-dimensional sign that lights up and presents the motivational statement, “Make Today Count!”. The sign is an assembly of 1/4-inch plywood that was laser-cut to allow for the plywood to interlock and form a box. In order to make the plywood interlock, each side of the box is comprised of rectangular tabs on its perimeter. The rectangular tabs were made using the Linear Sketch Pattern Feature on SolidWorks. Inside the box, there is a strip of LED lights that is programmed with an Arduino. The program allows the LED lights to show a specific color with a “dissolving” effect. The “dissolving” effect was created by having the color’s brightness follow a sine function. The sine function allows for the rate of change of brightness to be similar to a “dissolving” effect. For more details about the program, the program is submitted to Autolab. In addition, there are pieces of frosted acrylic placed behind the letters to allow for the LED lights to be presented more distributed around the letters.
