Our eyes continue to see light for a fraction of a second after the light goes off, and we can leverage this into fun blinkenlight toys like POV staffs. Sure, you can buy POV staffs and other devices, but they&#8217;re pretty expensive and you won&#8217;t learn anything that way. Building something yourself is often the more expensive route, but that&#8217;s not the case with <a href=\"https:\/\/www.instructables.com\/Persistence-of-Vision-LED-Staff\/\" target=\"_blank\" rel=\"noopener noreferrer\">[shurik179]&#8217;s excellent open-source POV staff<\/a>.<\/p>\n<p>There&#8217;s a lot to like about this project, starting with the detailed instructions. It&#8217;s based on the ItsyBitsyM4 Express and Adafruit&#8217;s Dotstar LED strips. You could use the Bluetooth version, but it&#8217;s already quite easy to load images to the staff because it shows up as a USB mass storage device. We like that [shurik179] added an IMU and coded the staff so that the images look consistent no matter how fast the staff is spinning. In the future, [shurik179] might make a Bluetooth version that&#8217;s collapsible. That sounds like quite the feat, and we can&#8217;t wait to see it in action.<\/p>\n<p>As cool as it is to wave a POV staff around, there&#8217;s no real practical application. <a href=\"https:\/\/hackaday.com\/2020\/08\/14\/abused-hard-drive-becomes-pov-clock\/\" target=\"_blank\" rel=\"noopener noreferrer\">What&#8217;s more practical than a clock?<\/a><\/p>\n<p>source <a href=\"https:\/\/hackaday.com\/2020\/10\/25\/pov-led-staff-takes-art-for-a-spin\/\">https:\/\/hackaday.com\/2020\/10\/25\/pov-led-staff-takes-art-for-a-spin\/<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The human body does plenty of cool tricks, but one of the easiest to take advantage of is persistence of vision (POV).
