Introduction The Light Messenger is a Persistence of Vision accessory for the Flipper Zero, allowing users to "paint" text and images into the air. It has a companion Flipper App that includes a fully-featured bitmap editor (for creating sprites without a computer), a text editor, light and animation controls - and even a flashlight function. The Light Messenger can also be used for light-painting, allowing you to create incredible images that slips into your pocket. Naturally, everything is open-source - and with 16 fully-addressable RGB LEDs, an accelerometer, and a feature-complete App, the Light Messenger was made to be customised and extended. Want to make colours change according to how you move the device? Totally possible. Want to show a different sprite with every swipe? Hack it in! Persistence of Vision Swipe the Light Messenger back and forth, and your designs will appear to float in the air like magic! Pocket-sized Light Painter With infinite light, colour and animation options, your Flipper Zero is now a fully-qualified light-painting device! How does the Light Messenger work? The Light Messenger has an on-board accelerometer, and can calculate its position in real-time. As you wave your hand back and forth, the device calculates the limits of each "sweep", and then triggers the 16 LEDs to paint "pixels" of light across the arc - which your eye determines as a floating image! The smoother you swipe, the more stable the image is - it only takes a little bit of practice to become a pro! 1 2 3 4 1.

HOWTO: LightMessenger The LightMessenger is slightly different / more powerful than other Persistence of Vision devices, because it can display images & text of varying lengths and varying distances. For example, if you're showing a text message, you might do longer, slower swipes - and the LightMessenger will calculate how big your swipes are to take advantage of the "full swipe" to show your message. Alternatively, if you're doing smaller, faster swipes, it will ensure that the message or image fits into your swipes. To perform these calculations, the device needs three swipes to calibrate.During these first swipes, it will calculate the distance of your swipes, and the speed of your swipes. Once these are calculated, the message will show. Speed is not the most important factor - it's being consistent. Try to make your swipes as uniform as possible. Don't worry - if you change the swipe speed or distance during use, the LightMessenger will recalculate. It might take a few tries to get the hang of it - but if you remember: 1, 2, 3 - Go! - this should help you get great results faster!
