PIC Based Laser Display

The main objective of the project is to obtain a 2D image file and project it using a laser pointer on a flat surface.

The design of the project utilizes two mirrors, two motors to move the mirrors, a laser pointer, and a PIC microcontroller with serial input to receive the image from the host computer and control the mirrors and laser. The Processing will condition and transfer the image and the result will be an image similar to a red or black old style computer display.

The mirror is a five-sided type which can be found on a laser printer and was mounted to a motor that is used to reflect the laser and draw each line. The laser diode on this type of printer should not be used because it can produce an invisible laser beam that could cause blindness. The fan blades were removed and an access hole is cut into one side for the laser to create the X mirror. To produce a complete image, the Y mirror needs to be setup to move the line up or down which can be done by using a hard drive read-write head.
