Ravioli – the Arduino-powered Laser Painter Project

And now for something completely different is the “Ravioli” Laser Painter. In summary, a laser pointer is fitted to a tilt/pan head controlled by two servos via an Arduino. The laser beam is then controlled to draw words on a wall. The text to display comes from a PC running a Python script. Furthermore the Arduino also controls the exposure time of a digital camera – when set to a long time, it can capture the entire writing of the laser pointer. For example:


This is a very inventive project and would be a lot of fun to make party or event souvenirs, or just as another form of random interactive art. For more information including code and design, check the project page. When creating projects with external circuitry to work with anArduino-compatible project – consider our range of ProtoShields. From the tiny LeoStick to the Mega range, we offer a complete range for you to work with
