There’s still enough time to at least -start- getting/ordering the parts for this MAKE weekend project before the weekend is over – in this video Jake McKenzie, Matt Dalton, and Bre Pettis show how to put together a persistence of vision gadget that you can put on your bicycle. Persistence of vision is a perceptual process where your brain holds an image in it’s head for a moment. This process is what lets us think that movies have people moving in them instead of seeing all 24 frames a second as individual pictures. This project programs LEDs to flash and appear to make words in the air. Watch the video to learn more and make sure to check out the instructions! – Link & get it on iTunes – Link.
