Finished Project:

This project was made as a Christmas/birthday gift to a friend, the basic idea behind the project is that I engraved an acrylic sheet with text and then when RGB light is shone through it, the engravings are highlighted.

The sign is powered by a regular USB-A connection and the colour of the sign can be controlled, allowing for either randomly changing colours or a fixed colour that can be set using trimmer pots on the bottom of the sign.

All of the woodwork was done by hand, with hand tools only and the RGB LED’s are controlled by an Arduino and a small circuit board.
