An impressive persistence of vision laser projector built using an Arduino and a hard drive case has been demonstrated by a DIY enthusiast. The device uses a circular array of rapidly spinning mirrors to produce horizontal scan lines, with the laser rapidly switching on and off to create line segments that form an image. The device can project one line of text with a maximum of 20 characters and is limited to a distance of about 90 feet.
