Blinky POV, $19.99
Persistence of vision (POV) displays have been around for a while. They use sequential blinking lights to create messages that appear to float in mid-air. While there are several several kits out there so you can build your own, there’s only one Blinky POV. What makes the Blinky POV different you ask? The way you program it! Most kits require a computer connection or microcontroller for programming. Not the Blinky POV. Just build the kit, go to a website on your smartphone or computer, and enter your message. Then hold your kit up to the blinking squares on the screen and the new program will be uploaded to your kit. It’s a simple project that’s easy and fun to use. Perfect for concerts, parties, parades, or anywhere you want to send a visual message.
