Open source persistence of vision (POV) light for bike wheels, pendulums, or hand waving. Multiple sensors to trigger the animations.

This POV light was developed with low cost and flexibility in mind. An Atmel 328 forms the core of the system, based on the Arduino Pro Mini architecture. TI TLC5940 LED drivers drive the LEDs. An Analog Devices 3 axis accelerometer, or a reed switch can be used to trigger the animation. A TI inductive sensor is also on the board layout, but is not yet supported. The various sensors allow the POV light to be used in a bicycle wheel, a pendulum, or just waving by hand on a stick. A TI boost regulator runs from one or two AA batteries and provides the 5V necessary to drive the LEDs at full brightness.

The boards can also be chained together to fill a bike wheel completely. There is an image converter tool that allows you to convert any image 10 LEDs high by 360 LEDs long (one for each degree of a circle). To make a larger image, chain multiple boards together with different images loaded onto each.

The hardware and software, including the image converter tool are all open source. The source files will appear on this page. We've built and tested several revisions of the design, and the current revision is running well.
