Light painting is an artistic medium combining light, motion and long-exposure photography. For as long as a camera’s shutter is open, a single point of light in motion will create a continuous streak in the final photograph. Digital technology takes light painting to the next level…dozens of point lights, with color and brightness individually under computer control, weave a swath of awesome across the completed frame. Adafruit’s NeoPixel strips, combined with the Arduino microcontroller and a supporting cast of parts, make highly refined digital light painting achievable!
Wear some space on your face and be a constellation for Halloween! This galaxy makeup is inspired by the Cassiopeia constellation and uses five FLORA NeoPixels to light up the night sky across your forehead, affixed with liquid latex. GEMMA and a coincell battery back reside on a hair clip and run the pixels in any color you choose.
These LED panels take care of all the work of making a big matrix display. Each panel has six 8x8 red matrix modules, for a 16x24 matrix. The panel has a HT1632C chip on the back with does all the multiplexing work for you and has a 3-pin SPI-like serial interface to talk to it and set LEDs on or off. There are a few extras as well, such as being able to change the brightness of the entire display, or blink the entire display at 1 Hz.
The NeuroDreamer Sleep Mask by Cornfield Electronics is a meditation device that flashes colored lights at your eyelids and plays brainwave beats for your ears to help you fall asleep, have lucid dreams, or for meditation.
