Earlier this year we showed you how an LED POV staff could be used to visualize network data. This build takes it to another level and allows you to imprint entire words and images into photos.
Gavin, a hardware hacker from Sydney, built an open-source POV (persistence of vision) staff after the Wi-Fi visualizer inspired him to begin playing with large POV builds. He built his POV staff using LED strips, wireless controllers, and a laptop to send the signals at the proper intervals to the staff. He can write words, create images, and even send Pac-Man racing across the frame.
