The "Pocket Pixie" is a miniature air writer that leverages persistence of vision (POV) technology. This compact device can easily fit inside any pocket, making it an ideal companion for anyone on-the-go. By simply pressing a button and waving the unit, text appears effortlessly in mid-air. To input your own custom text, all you need to do is modify the attached Arduino file and upload it to the ATtiny chip. For ease of use, place your text within Excel or jot it down on a piece of paper, then fill in the corresponding LEDs. If designing a PCB proves too daunting, consider using a piece of perfboard instead. To ensure reliable contact between the battery pins and their openings, gently bend them inward before inserting.
